Ok, I've been searching these forums for quite a while now researching a +T conversion for my 1984 245 (B23F w/ M/T so 9.5:1 compression ratio, LH 2.0) I've got a turbo w/ header, intercooler, green top injectors, 3.0 FPR, but now I think its going to be a little more involved because my car has LH 2.0.
It appears the reccomended way to acheive my goals (stock turbo level boost, nothing more nothing less... but if it has to be more OR less, let it be more ) is to get rid of the LH 2.0 completely, and replace it with the LH 2.2 (and not 2.4 becasue of crank position sensor?) from a 85-89 740 turbo (local pick and pulls are full of '87 740 turbos at the moment...) before I go about doing this and buying more parts from the pick and pull I want to make sure this is the way to go for my year/setup.
How easy is replacing the entire harness with 2.2? (I probably should do it anyways before my stock one biodegrades on me... ) Should I take everything and anything connected to the harness? Is it a complete plug and play process? Should I just grab the whole intake manifold/fuel rail/TB as one piece and just replace mine? And will the down pipe from a 740 work with my 240? (going to need to be welded in anyways, my exhaust line has been cut and welded together by so many shops in the past 20 years I dont think there are any more bolt together parts on it...)
I have a T cam, I read a post where some here say its not much better than the M, but if Im just looking for stock like turbo performance, is this what I should put in?
My last question for now... I pulled my turbo a long time ago (a year or 2), I know what the oil intake and drain holes are, but what are the 2 threaded holes on the sides of the turbo for? I know they use the banjo (?) fittings (the screws with holes for liquid to pass through) Do those go to an oil cooler? I havent been able to find a good pic or description online to remind me what they went to...
Thanks in advance for any answers/ encouragement you can give me about the +T project, and Im sorry if these questions have been asked before, I really have been searchign for hours and hours.
