Simonster, could you please tell me how much those Arias forgies set you back by?

Joel, what about forged piston + conrods... last quote I found was quite murderous... 666DAN, how much would it cost to get it shipped into Australia though? I heard that the customs/freight people are quite mean...

But 666Dan, thats what i mean though, i don't want to spend 3k - 4k + to get forgies if i could find a DET neo head for about 1k.....

perhaps experienced people who has access to these things (sydneykid?) could clear these questions up for us? a head would be a much easier and cheaper thing to replace than pistons and rods for me.. plus i could probably replace the cams at the same time...... hmm.... maybe I would take a trip down to the traders and ask their sales to let me take a peek at their catalogue? any chance of that happening?

Hi guys, been following this thread (and 666dan's conversion) with much interests as I am trying to find a 4 door R34 as well. Currently I am trying to choose between a RB25DET neo and a RB25DE neo. The non-turboed car is newer (by a year), comes with tiptronic controls and costs substantially less than the turboed car. However, since ultimately I am interested in getting a truboed car, a turbo conversion on the RB25DE is guaranteed should I choose to purchase it. 666DAN's comment on the NEO engines nearly having the same internals had me very excited. The reason being I currently have in possession all the neccesary components for turbo charging the car (intercooler, turbo, exhaust manifold) and it would work out cheaper for me to turbo charge the N/A car than to purchase the RB25DET car. I have found the following information on the two engines while researching: RB25DET NEO (GTT) 24-valve turbo EFI straight six Capacity 2498 Bore x Stroke 86.0x71.7 Compression 9.0:1 Power 207kW @ 6400rpm Torque 343Nm @ 3200rpm (auto 333Nm) Kerb Weight 1410kg (1440kg auto) 0-100 in 6.0 sec flat 0-400m in 14.2 (tested by reviewer) RB25DE NEO (GT25) 24 valve EFI straight six Capacity 2498 Bore x Stroke 86.0x71.7 Compression 10.0:1 Power 147kW @ 6000rpm Torque 255Nm@ 4000rpm Kerb Weight not stated 0-100 in 8.7 sec 0-400m covered in 16.3 Can someone clarify just exactly how "nearly the same" are the two engine internals? From the bore x stroke and the compression ratios its clear that the pistons between the two engines are not of the same size if both engine blocks are the same. Are the engine block the same? What about the crank, conrod (length and strength) and cams?

ppl... if you have an engineering related quesiton... why not read the RB30 sticky?
