TRUST 88mm forged pistons (2700cc) R34 crank, HKS cams(unsure of spec) and conrods, HKS 2540's turbos and actuator kits, Apexi power FC ECU, Nismo twin plate clutch, HKS turbo elbows, uprated downpipes, Greddy titanium exhaust, Nismo fuel pressure regulator with 800cc injectors, SARD alloy rad with Earls connectors, braided hoses on water lines, HKS Induction, Super Magtune on fuel line, HKS hardpipe kit, trust Intercooler running 1.7bar of boost and ment to be about 700bhp.

If this was the same spec but only a standard rb26, what would happen? Would it take awhile to blow up or would it just not be possible to run that sort of boost in the first place?

Cant run that boost on a standard RB26 to start with.......and those 2540's would be horribly laggy........Tony (M19GTR) used to have a set on his R33 and it was laggy as ****!!!

so basically it's the increased displacement that is required to push the bigger turbos? what's a good match for a 2.8l setup (twins)?

Gordon and Incubus were both running 2540s on a stock bottom end although only pushing them to 1.4 bar from memory.

Both were running mid 11 quarters and very quick cars...

would running 1.4 bar in a standard block feel very similar to running 1.4 bar on a 2.7 then? or would it feel alot less laggy?

Driving the car wouldn't let you determine if its a 2.7 then?

Is there anyway except for taking the engine apart to find out if it's running a 2.7 on the spec mentioned? e.g it would show a higher knock on the fc commander if running standard block etc(sorry if thats a stupid eg)

2540's on a STD RB26 will come on 1bar boost at around 4300rpm thats what mine used to anyway, as for boost on a std RB i wouldnt run more than 1.4bar and thats still pushing it, basicly the more you run the quicker it will go POP.

sounds like the car that was for sale at gtcars? am i right
laggyt turbo's just need to get it remapped
take your plugs out at check for markings on your pistons, a 2.7 engine should be less laggy mind you big cams for the 2540's
