RITE.......................!
Need some "sensible" advice on wich engine to use.
Plan is I have an 2001 model MX5 on the way, lots of front end damage, but nothin I cant sort out.
At first I was planning to put a chevy 350 short block in there, but after the last one i ballsed up, im not gana bother!
Choices are,
Fairly standard sr20 or
Rb25de with performance throttel bodies conversion, high lift cams and mappable ecu upgrade.
Both engines are the same money, but wich will perform better?
not usin the car sor drag or drift or anythin, just a fast as fcuk street racer.
Always wanted a 2 seater monster, had an mr2 and cant afford a TVR so this is totaly my own thing.
Susspension setup is sorted one the engine is finished so the extra weight will be counter acted with the susspension package.
Another concern is the reliability of the engines,
SR20 is prone to bottem end nock, expensive to upgrade, and the extra heat of the turbo and fitting of the intercooler could make life extremly difficult.
RB25de is slightly bigger (understatement) and weighs more, but the upgrades i have on the shelf and I dont have the problem of the heat and intercooler, plus a 50bhp shot on Nos will see it fly!
Or would I be better of with throttel bodies on the SR20? better low end torque is a must in this project, Ive had turbo's and i have an RB30 R32 project on the go so this is purely for fun!
Any suggestions welcome!
