Re: cheap turbo 3.0 using a factory ECU

For how long?
Would it run 8lbs with a motor with 160k?
Would I need a prf. Clutch?
I saw somewhere that after 6psi you'll need a better clutch
Thanks for the help

Re: cheap turbo 3.0 using a factory ECU

well believe it or not I have seen 3.0's with close to 200,000 miles and be boosted up to 18lbs!!! with the wear on the cylinders it will increase the ring gap and help with heat expansion on the piston. a better clutch would be nice. I got mine from centerforce. but a good clutch will make your day!!!

Re: cheap turbo 3.0 using a factory ECU

8lbs is more than enough boost to have fun with a 3.0!! i dont suggest 18lbs lol without heavy modding

Re: cheap turbo 3.0 using a factory ECU

Means that it is mounted on the exhaust crossover tube. The exit of the rear manifold is plugged to force exhaust through the turbo.

Re: cheap turbo 3.0 using a factory ECU

How much power are you looking for?

8-10 psi should have you over 300hp I believe. Ondonti ran low 20's for boost and put down over 500whp, so it's all based on what you are trying to achieve.

Not to dissuade you from your high power goals, but there are a few other things you might want to consider in your high-power build

the 500hp range can be undriveable at times, Ondonti was getting wheelspin with slicks in 3rd at speed on the road.

A few things you may want to look into
1) an LSD, at 500HP, is probably a necessity
2) a not worn-out suspension
2A) better yet, rbryant has a full coilover setup from BC available with selectable spring rates, along with polybushings EVERYWERE
3) 500HP would be best served with some kind of aftermarket ECU (AEM, Megasquirt etc)
4) Upgraded fuel system (255lph pump and larger feed/return lines, with a Standalone, you should be OK with a stock FPR
5) BRAKES!!! - going fast is easy, stopping is the hard part. upgrading to bigger better 4-wheel disc brakes would be a VERY good idea
5A) TIRES - Brakes only do so much if you have crap tires
6) essential gauges are also a good idea, oil pressure, oil temp etc. Don't want to lose an engine due to oil pressure loss and the like

Re: cheap turbo 3.0 using a factory ECU
