Addicted2Boost

Ok so another few weeks pass and its close to 2 months now after payment and still no response... Basically its like ive been the victim of theft of $1300 from this guy. Still no answer to any of my calls or emails. One time he picked up but hung up straight away, calling him again and again, as usual no pickup. Paypal is absolutely useless aswell and dont see the point, as after escalaing to them and them deciding in my favor, told me they cannot recover any of the funds.... great, so what now??? I dont have any other choice but to report this to the authorities?? And something like this im sure its going to be a very long winded process.... Looks like he said thank you very much to my $$ and there is not much i can do about this............ SO WARNING TO ANYONE WHO IS GOING TO PURCHASE FROM JSAI.... ESPECIALLY IF UR NOT IN AUSTRALIA... SIMPLY DONT. HE WILL ANSWER UR CALLS AND RESPOND TO EMAILS ON A DIME BEFORE U GIVE HIM UR $$ BUT AFTER YOU PAY HIM, SILENCE... NOT A WORD BACK.... Almost 2 months from payment and he said items should arrive within a week... yeah right.

That would be helpful thanks mate! Im just very very curious why he wud dodge my calls etc... i mean any communication is better than dead silence...

OK Guys, I really didnt want to post this about JSAI and wanted to give every benfit of doubt to Josh at JSAI, but i dont know what else to do really.... Basically i had concerns about the service as alot of ppl were complaining about JSAI, but after his very prompt emails back to me on shipping costs and picking up his fone regularly i was thinking it was ok to make the payment etc... and that he finally sorted out his business practice etc... So i make the payment of almost $1000AUD on the 5th of may. He says he will get everything sent out first thing monday and going through air frieght will be arriving to New Zealand within a week... 5 days go by so i ask him if he has sent it and if i could get the tracking number.... which he asks for my contact number?? (Which i supplied in Paypal and in my initial emails) anyways, i provide this. Another few days go by and ask for an update. No reply.... 1 week passes and another email... no reply. A further 10 days go by and email him again for update... no reply. During this whole time of various emails to him, everyday i have been on the fone trying to get a hold of him and leaving him voicemail messages. It gets full at one point, (obviously with other VM from customers as well) then a few days later i can again leave messages, which means he is available to clear these messages... still no reply and still no answer of his phone or reply... Wat can i do now?. I mean, whatever the reason, wouldnt you think to update your customer on what the hell is going on? But total dead silence?? I think this would be the worst business practice ive come across.... Has anyone else dealt with JSAI and DID NOT RECEIVE the parts? Basically taking ur $$ and not sending you the parts at all? Whats the next steps i can take as i am in NZ. I have now reported to Paypal regarding the transaction...

UR a clown, thats all it is. haha, What are you worried about the result, of a rolling dyno as i posted above might get a similar power to a hub? Falling back on me going to the strip?? That is you whole point from the start, dont go and start changing it and falling back on the strip 1 - Other people in rolling dynos have posted 300kw @ wheels on THIS forum using stock setup. 2 - There are 11sec GTRs on STOCK setup 3 - THat is the whole point about accuracy. Im saying hub dynos are more accurate and used widely and is passed on as "@ wheels" you are saying only a rolling dyno is (but as everyone knows, too many variables get in the way of a result) Why dont u hassel everyone else and say only way to measure power is on an engine dyno then? 4 - 1/4 doesnt interest me that much. That was early and mid 2000s. Frankly its for numb nuts. GTR wasnt made for drags and also If you get a 4wd controller and get the launch better you can get better times anyway. 60ft times on a GTR is not as great as an EVO (street tires) etc... So 1/4 doesnt prove jack. Look at R35, heavy as, "only" 500hp posting mid-low 11s. So i should be doing 10s then?? I havnt heard of street 300kw GTR doing 10s. Even a light RWD GTST making 300rwkw on street tires will have a hard time posting up 10s or 11s for that matter. So again, its all varied. 5 - You say stupid shit like "you cannot make any more power on cams with the same turbo size at same boost which = flow rate of turbos. Then try go back on ur words. 6 - Already shown you the hub dyno used on my car, R35 making 297kw @ wheels (hub) which is pretty dead accurate and is what rolling dynos are recording. So yeah watever, im done with this thread. The only thing you have to fall back on is me running the strip... yeah good one. Why dont you start blabbing to everyone that the dyno readout is shit and say only tru power is getting it on an engine dyno? Or hassel a RWD 300kw gtst on street tires running low 11s?

This has made me look into rolling dynos a bit more actually. Found this http://www.gtr.co.uk/forum/14053-dynapack-...d-straight.html So even with NISMO, APEXI,TRD, Trail etc... using it, like i said these days its commonly referred to as @ the wheels. As its more accurate. Dispite this have found numerous examples of power measured at the "wheels" on a rolling dynometer with the kind of power equating to mods i have been standing by. http://www.gtr.co.uk/forum/109582-449-9hp-...ard-turbos.html Making 260kw @ wheels without even an aftermarket ECU or boost controller or cams etc.. Factory turbo and injectors @ 1.1bar. Been through 2 pages of the RB26 thread on here and already found 2 that are running almost or just on 300kw @ wheels on a Dyno Dynamics a rolling dynometer. End of the day mate, i have enough information provided by various sources to base my beliefs and obviously you do aswell. But I dont think im wrong at all (backed up by the thread you pointed me to) and I believe you are wrong on many counts throughout this thread on lots of points. I dont need to run on the strip as i dont have anything to prove. Whatever the result theres no convincing someone like you. You go on believing what you will. About the turbo, im not putting words, that is in-affect what you are saying. No more power at same boost levels. Whats the differnce to the same turbo at its airflow limit as opposed to airflow at 1.2bar. Was i running them at like 2 bar outstripping its efficent operating airflow? Like i said i ran the same boost level of 1.2-1.3bar. Can you not read? Its the same AIRFLOW. There are heaps of ppl running 1.3-1.4 bar on stock turbos with upgraded steel shafts or N1 turbos. So it certainly is not way past its efficiecny/airflow limit at 1.2bar. Its about air efficency getting into and out of the engine. Again a rolling dyno has too many variables (even tire pressure and or alignment can give a differnt power figure) and a hub dyno will be closer to the wheel figure. But just for my interest i will run my S14 on the hub dyno at ST HITEC to see the differnce. It made 210kw@wheels on a Dyno Dynamics rolling dyno a few years back... So you are saying i should expect around 250kw@hubs? It perhaps will be more, but not by 40-50kw....

No no, dont go back and changing it. You said u cannot make more power on same turbo size and same boost levels... = WRONG It was 40kw and wasnt cams alone. Like i said, he leaned out the af/r a bit more and also i had adjustable cam gears. Also the twin turbo pipe was modified so air from turbo 2 and 1 joining is going the same direction. UK guys have confirmed about 4-5kw @ wheel increase alone on standard boost (confirmed by ST-hitec) by doing so. And FYI i have also read other people using TOMEI 260 9.15mm cams and gears getting 50hp+ increases. Again you are wrong for saying that only 1 reason for people quoting higher is because they are new. The 34s boost higher from the factory 1bar as opposed to 0.8bar on the r32. Manufacturers always put in some 'acceptable" leeway for reliability and i dont see any reason why the R34 would had less. Why would nissan make a turbo thats about to break on FACTORY boost setting? If anything they addressed shortcommings of the 32 such as they did with starvation etc... As you know the 34s are Ball bearing, meaning easier to spin up. Less force is required to get it boosting, perhaps thats why you find the shafts snapping on the earlier models. So other than your basic knowledge that it breaks because its ceramic, why does it break? ultimate spin speed, spindle/shaft acceleration? which the ball bearing will no doubt help. Anyways, yes i did check out that thread... looks like most are R32/R33, but theres one R32 using a R34 engine on pretty much similar mods as me, but importance on him having STANDARD INJECTORS, STANARD AFM, INTERCOOLER etc, making 300kw @ wheels on 18psi (1.2bar) on a Dyno Dyanamics. IF you dont know already, its a ROLLING DYNO... hahaha... Mate, the thread you were pointing me to just proved you wrong.

LOL... no of course i dont believe everything in a mag, but when the journos in it tune and race cars themselves yeah i tend to believe it over other sources. LOL, dont just say because i was using a HUB. And you've totally ignored what i said about the R35 KW figures on that hub. Also again according to you, there is NO way you can make more power on same turbo size and same boost levels by adding high lift camshafts. Because you are a "person with knowledge of things" right? And you can set everyone straight here? Im sorry but thats just bollocks. Because that is your whole point at this stage. I would have thought the same as you did, and I also havnt seen an R32 or R33 making 300kw on stock turbo and injectors setup, i admit that. On hubs or whatever. The R34s although ceramic, everyone seems to have a higher boost level quoted for them compared to the 32/33. Even at the same tuning shop he was pleasently suprised and said that is very good power, but everything maxed. FPR, FPR... you keep going on like its a power making mod? Injectors, FPR and pump are all just supporting mods and not power mods. Like i said most people do the turbo route and support mods and do the cams at the same time instead of adding cams to a standard setup like ive done. So to validate your comments, show me another R34 example with the same mods running 1.25-1.3bar and rolling dyno figures. Just because most examples with standard setup show under 300kw you refuse it and just put it down to "oh its just a hub figure". Also its down to the tuner. He did mention that he did lean out the A/F ratio even further, so im always keeping an eye on the knock levels. Every car is also differnt. The same day i was getting mine tuned for the first time, another black R34 Vspec with same mods, Power FC and exhaust, I was getting 270kw @ 1.2bar consistently while he only managed 245kw @ wheels @ 1.3bar, which is the normal figure everyone sees. The guy was sorta complaining to the tuner asking why mines making so much more on same mods. Anyways get used to it, everyone knows its more accurate than a rolling dyno.

I know all dynos are different, goes without saying, but thats a pathetic excuse in trying to back up your stuck idea. Yes a rolling dyno vs a hub dyno.... i know the hub will show more in most cases. However a hub dyno is far more accurate as most people accept and some even going as far as to say "real" dyno. With the rolling dyno there are too many variables to consider and even your alignment of ur wheels to wheel weight, slip etc.... At the above tuning shop that i take my GTR to, they had a factory R35 GTR making 297kw @ wheels. (or HUB should i say...) which equates to pretty much what most guys on rolling dynos are getting and is in line with what the engine should be making too. (Funny thing is, guys on rolling dynos are posting higher figures than this hub figure for standard GTRs and yet to see a lower figure than 297kw....) Also, how do you explain that aussie GTR making "271kw @ wheels" on power FC and exhaust in SPEED mag? Perhaps they were also using hub dyno???? Whatever the case, it is commonly and widely accepted as "wheel" figure. That power is exactly what i made on same boost levels with the same mods. Yeah the turbos rated at a certain HP and cannot flow more... so just because of this fact are you telling me an engine cannot make any more power whatsoever beyond that? After my second stage of mods, it ran on EXACTLY same boost levels, spiking up to 1.3 before settling to 1.25. There is more power everywhere across the entire rev range peaking at 310kw. But according to you that is impossible if the same size turbos are flowing the same boost it CANNOT make any more power?

Mind you, maybe cos the route i took with the mods is slightly different? Cos most ppl do the turbos, injectors, AFM, Pump first instead of CAMS and the turbo outlet has only recently being modded. (Adding a divider plate where turbo 2 joins turbo 1) Cos when i was posting about doing cams etc, i DID get a bit of flack saying its sorta taking a wierd route in doing mods, and should be done after the turbos. And yes alot of ppl recommended i dont skimp on fuel. But my budget was small so really couldnt do that. But was very happy with the end result and the route i did take.

LOL, thats nice... perhaps you know alot to say something like "there is no way" instead of just enquiring to get more info.... The GTR.CO.UK guys never have questioned that power level for the mods... neither has infamos RIPS in NZ. Have you heard of ST HITEC? He is pretty much 'the' guy here in Auckland to take GTRs to. He done most of the work on my car. Dispite NZs low number in GTRs, everytime i go there he has atleast 2 GTRs hes working on. Also has had 2-3 R35 GTRs there already. He does a blog and tunes alot of cars. Even had a Lambo diablo V12... haha, but only made 250kw @ wheels. I dont think the numbers are wrong at all, becuase the cars he tunes aswell as GTRs (EVOs, STIs, S2000) produce and corresponds to numbers that other people are reporting based on the mods. FYI, Speed magazine which i prefer over fast4s etc... had an article a few years back comparing EVO7, STI, and R34 GTR doing basic mods, all exhaust and ECU and the 34 made 271kw @ wheels. Funny enough, i made 270kw. Since then, ive done Apexi power filter in factory air box, modified the twin turbo outlet pipe (dyno proved in UK and in NZ to make 4-5kw @ wheels on factory setup) and added Tomei PonCams and adjustable tomei gears. Clutch never slipped at 270, and started to on my next stage of mods, so ended up having to get a NISMO twin plate with NISMO lightened flywheel etc... An R33 GTR in the UK that has exactly the same mods as me is also making a tad over 300kw @ wheels with the above setup (using R34 turbos).... Check his site out, interesting reading... if u dont mind the broken english haha. http://www.sthitec.co.nz/ http://sthitec.blogspot.com/

Thanks Terry, Yeah i still remember your car from last year! You sent me an email of pics of your car and yes they are nice. But they were just sideskirts, really wanting to see how large surface areas will come out as such as a front bumper or the z-tune guards. U done anything else? Oh just an update on my car, added tomei cams and gears and modified the twin turbo pipe... made 310kw @ wheels all on factory turbos and injectors. They are pretty much maxed out of course, but very good response from factory turbos boosting 1bar below 3000rpm... makes me sorta turn away at the idea of so called "response" 2530 turbos when it comes to my next engine mods.... seen some charts and it needs extra 1500-2000 rpm to get 1bar... same goes for power, up to 5000rpm factory turbos make more power...

Hey Guys, I dont come on here much as im in NZ, and even NZ has hardly any GTR owners, so im usually on the GTR.CO.UK fourms.... Anyways, i wanted to do a quick search on Google on the quality of parts that JSAI produce before i made my order, and i found several threads of questionable business practices by them. Now being in New Zealand, that would be an important consideration given the distance etc. Late last year, I experianced some of the concerns that skyline owners in Australia were having.... Even enquires were given back with 1 line replies and further enquiry's just ignored... So i sorta left it trying to get some parts here. But since NZ is so damn small, looks like i might need to order from JSAI. Wanting to get a host of parts like carbon bonnet, rear pods, front diffuser etc for my R34 GTR Just weighing up if i shud just get a front diffuser for my GTR or get an entire replacement with Z-tune front bar. For large parts like a bumper, how is the quality, cos i know that fibreglass seem to be very "lumpy" and not as smooth as plastic/genuine OEM parts. Can someone post up pics of JSAI parts like front/rear bumper. Seems like issues of not replying, long wait times, mis match of ordered parts, etc have been ongoing since mid last year and into this year... has any recent guys on here experianced a turn around? As this is a big concern for me... Also the quality of parts. I would love to see some parts in person, but well...

Thanks! Yeah i need to definitly need to get a front diffuser tho, everytime i look at it, its like something is missing! And some rear skirts... and might go for the agressive look at stick on a Z-tune bonnet

Thanks J Spec, i will contact you guys sometime directly to discuss further
