lets say that we have a 87-88 TII engine.if we decide to swap the stock turbo with a garret t04 fitted on hks manifold,also fit a RacingBeat exhaust system and a hks fcd,what could be the result?

can the stock ecu afford the upgrade and how?

 

you would need bigger injectors, and then a new ecu to run the new injectors...

 

if you got a pretuned ecu might be able to run low boost

 

The result, more than likely, a blown engine.



You need more fuel for all the extra air you'd be pumping into the engine.
