R34 GTT automatic (Tiptronic) that previously had 150rwkw stock and 199rwkw with basic bolt-ons, a bit of boost and Nistune.

The setup:

  • Hypergear ATR43-SS2 internally gated on stock manifold
  • Stock airbox and snorkel
  • K&N panel filter
  • Z32 AFM
  • Scotty's 3" intake pipe
  • Trust turn flow intercooler
  • Turbotech V2 manual boost controller
  • Yellow Jacket coil packs
  • NGK BKR7EIX spark plugs regapped
  • Deatchwerks 800cc injectors
  • Walbro 255 LPH fuel pump
  • JJR 3" bellmouth front/dump (modified)
  • X-Force high flow cat
  • 3" HKS Super Drager cat back (modified)
  • Davies Craig Hydra Cool 678 auto trans cooler
  • Nistune


Result: 257rwkw @ ~17psi, BP 98 Octane
Installed and tuned by Chasers

This is a fairly conservative tune. For some more power, the car needs a better boost controller, possibly a pod intake, and a shift kit.

Had the Torana retuned on the 25/10 by EFI at Southport on the Gold Coast.

Eng RB 25 NEO std bottom end

Head ported stage 1 pom tom cams lighterned flywheel and 6 puck sprung button clutch.

Manifolds Std Manifolds

Turbo op6 rear housing Hi flowed steel wheel fitted

Injectors Bosh 550cc

Coil packs Spit fires

Exhaust 3" turbo back 100 cell cat straight thorough muf

Nistune chip

Fuel BP98 with C5 fuel additive mixed at 1 can of c5 to 30t of bp98.

Boost spike to 18 psi to get out of the hole drops back to 14 psi for top end (actuator not holding needs upgrade)

Made 285KW@W or 381HP@W depending witch way you want to look at it.

So to have the same power to weight ratio you have to make around 480+ hp@w in a skyline. 2.88hp to every kg the car weight.

Is lots of fun to drive and can make 100ks in just over 3 seconds. 60-170 and back to 0 in 250m.

S1 R33, Tuned by Shaun @ Boostworx

Rebuilt RB25 - CP Pistons, ARP Hardware, GReddy Head Gasket

Apexi Pod/Z32 AFM

Greddy TD06l2-20g 10cm Turbo/GReddy SUS Highmount Manifold/Tial MVR44 Wastegate/Turbotech Bleeder

HKS FMIC, Plazmaman Piping kit

Nismo 550cc injectors/Nismo Adj. FPR/Nismo Fuel Pump

APEXi Power FC ECU

3 inch exhaust

270 rwkw @ 19 psi, tapers off to 16 higher in the range, We think the cat (Unknown) might be causing a restriction, so will replace with decat pipe, and remove turbotech and switch to Power FC boost control to maintain boost levels a bit more, but seems turbo is pretty much at it's limits on pump fuel.

May entertain E85 later on, But very happy with the outcome. Midrange is ridiculous, and destroys 235's with ease.

HI All!! just though i would share with everyone my Car and what she made and mods! post what you have , i would like to see what others are running!

im from WA Bunbury

Got it dyno tuned yesterday (Monday)

Mods are

Garret High Flow GT3076R from Adelaide Turbo Service with Factory Rear and front housing

Nismo 740CC Inj

Exeedy Heavy Duty Clutch

Walbro Fuel Pump

Custom Stainless Intake with Cold air induction

Autobahn88 front mount intercooler

Spitfire coil packs

Iridium spark plugs gapped to .08

Full turbo back split dump HKS 3 inch Exhaust with hot dog and streight through rear (Milo Tin)

HDI Electronic Boost Controller with high and low settting

Haltech Platium Pro ECU

It was a very hot day yesterday! outside temp was around 32 Degrees, the dyno room was 38.5 so it was hot!!! so that would effect the tune a litte bit..

on 19psi i made 359.2 RWHP , took it for a drive and it was nice but didnt like it very much to much wheel spin, so wound it back to 17 PSI which was the sweet spot between good traction and no traction for Final Run and it pulled 337.3RWHP on 17PSI i was happy with that, i can wind it up have a little play if i want as it was tuned to 19PSI

on 10PSI LOW Setting i made 278RWHP

Thanks!!

Cant wait to get it on E85!

Next is upgrade clutch and change rears then up boost

Back again with E85.

1000cc injectors

unopened rb25.

R33 21U hypergear hiflow (new revision) touching 20psi, back down to 17-18ish top end

splitfires

FMIC

walbro GSS341

3 inch turbo back exhaust with quiet-ish muffler

3 inch intake from scotty. Pod filter

Z32 AFM. Z32 ecu nistune.

etc

Wheelspinning on the dyno with soft 235's made 281rwkw but the power curve was up and down when the wheelspin kicked in. We upped the ramp rate to 35km/h/s and had 2 blokes sitting on the boot and it made 306rwkw but Toshi reckons that's a bit high, more like 290-295 realistically . anyway here are both dyno sheets make of it what you want.

E85 is pretty amazing. So much knock protection

    • Slimline sub on the rear parcel shelf is doable. Pioneer TS-WX140DA is only 70mm high.   
    • People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.
    • What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
    • Easiest way to know is to break out the multimeter and measure it when cold, then measure all the resistances again once it gets hot enough to misfire. Both the original ignitor and the J Replace version. Factory service manual will have the spec for the terminal measurements.
    • Yes that sounds right. Cars currently in the shop for the engine work. Will need to remeasure .. but yes I think I must be targeting 45cm from fender.
