Turbocharged 2.8L??

[Ortie666]

Does anyone know of a computer/manifold used in the old ironhead 2.8L's that can reconize boost? If so witch cars did it come in??

[sharkey]

none of them came boosted, but that doesnt mean you cant boost one. you could use a tgp ecm. it will run a 2.8l with a 2 bar map for boost.

tgp?? little new to fuel injection with these engines...

TGP = Turbo Grand Prix, available in the early 90s.

Only problem I see with running the TGP code is it runs off of DIS, no distributor. I'm not saying that it can't run off a dist, but I don't think it is ready to stock. You can just get a chip burnt for a 2-bar map sensor for a Fiero ecm. That should also work well for your setup. That is what I ran for about 8 months till I went with a stand-alone ecu.

you should get into it, once you stick with the ecu/code you want to use, youll figure out what does what. there are only a handfull of things to adjust in the code. and ya got us for all your questions

i saw a superchager for sale on i bay that was on a 2.8 s-10 with a 2bbl carb that would be a direct bolt on wouldnt it ?

[Ortie666]

ya the 2bbl supercharger would work, but im goin for reliability this winter, not knocking superchargers or carbs.. I want somthing that I can bag all winter and a turbocharged m.p.f.i. sounds like the ideal winter engine in my mind..

So who burns these chips for the fiero ecu's and how is it done?? Im electronicaly inclined I so would asume I could do it myself.. also is it olny the fiero ecu or can u do it to any of the mpfi ones??

[Ortie666]

Anyone Anyone?? goin to the junkyard tomorow, and wanna see if there is any ecu's that reconize boost or can be perswayed into reconizing it.. besides a fiero??

89-90 pontiac grand prix 727
some sort of jbody 730 ecu

ones behind glovebox and the other is in the engine bay
depends how ya wanna go
both will run 8f code

[Ortie666]

Sweet, Thanks alot budd!!

Probably a little late, but you don't neccesarily need a map based ecm to run boost on these engines, the maf system that came with many iorn-head engines can be used with a turbo setup. Tuning is mandatory nomatter which route you take, but if you wanted to go the maf route you'd have to place the maf sensor before the turbo to read actual airflow. Placing the maf after the turbo would give false readings because of the heat turbocharging produces (the housing might leak too). Another benefit of using a maf system is that theoretically you're not restricted to how much you can boost your engine, map systems can only read pressure up to a point (2bar rating=2x atmosphere). Food for thought.

Then get a 3 bar. Thats almost 30LBS limit which is alot for most cars runing pump gas on the street.
