I have a super clean car finally, in the colour I wanted and am super happy! The car is modycoddled and will never be anything but a road car never likely to see a track either. Anyway my theoretical engine rebuild would be a car with circa 300ft/lb and I want it at 2000rpm and a flat tourqe curve from there. The TTrs engine delivers 330+ at 1700rpm with an extra 500cc and a borg warner I know, but any suggestions please clever people!!!
Opinions on engine spec please people?

Good luck, the 2.5 TSFI has a CGI block, direct fuel injection, variable valve timing and a static compression ratio of 10:1. It'll take some serious re-engineering to make a 10 year old SR20DET perform like that, well outside the scope of a normal rebuild.
What sort of power output would you be after? I could suggest a build that would easily hit your requirements but would feel restricted at the top end and limit top end power.

Gas is cheating, so is E85

High compression,advanced cam timing,ported and polished exhaust ports, 5 angle valve job,small hybrid turbo on custom made manifold with small primarys to keep gas speed high,have crank massively lightened, aluminium flywheel,
I have gone for bottom end like your asking and very happy with my results so far. I went with the Turbine tech manifold from Canada with a custom Evo turbo. My engine builder has also set the cam timing to help it come on sooner as well as porting the head. I haven't got the dyno sheet yet but my tuner said its coming on very hard very early and has great drivability

Buy a diesel.
You getting old and sensible?
Nah! lol. He just seems to want the spec of a diesel engine from a petrol engine. I never understand why people want mid range torque so badly. Stop being lazy and use the gears. It's got a redline, use it.;-) I once tried changing at 7000rpm instead of 7500rpm on the strip and it was slower over the 1/4, so I'm guessing 6500 will be slower still.
Plus I've been in Dave's diesel and it pulls like hell.

That sounds like a comment from somebody that hasn't got any :lol:
I know what you mean about modern diesels though, my mate has got a 335d with a remap and its over 500ft/lbs :shock:
