2.2L Sonoma

Hey everyone...I am interested in doing my own custom turbo setup for my 99 GMC Sonoma. Its got the Vortec 2200 motor in it and I am planning on keeping the internals stock. The compression ratio is roughly 9:1 and ive heard that sort of compression is good for a turbo and my stock internals can handle up to 7 or 8 psi boost. Before I go into any more details and making more of an *** of myself by spouting out falsities of what i think i know about turbos...has anyone done a custom job on the Vortec 2.2 motor? Things like fuel system mods/custom exhaust manifolds/best suited turbos...?

Thanks in advance to anyone who replies!

Do a search. I remember someone did a turbo S-10 awhile back. This was at least a year ago. If you can't find it using the HMT search, use google to do a site search for it.

Alright, thanks for the maps platanazo64...CRX...i did a search yesterday and saw a thread about the guy who set up his turbo on the s-10...but he didnt say what kind of turbo he had on it...it was just about his fuel managment. Speaking of fuelmanagement...my stock injectors are high-impedance 14lb. injectors and ive heard of guys just slapping on high-imp 28lb GM 3800 series injectors and running OK...but idleing like ---- (flooding out). What do you..or anyone else..think would be a good fuel managment system that i can just piggyback or tap into my existing system with? (I will most likely go with the 28lb. injectors+ a fuel managment program...)

Thanks,
A.J.

allright..i found that guy who put the turbo on his gen-I s-10 with the 2.5L motor. LOL sounds like he screwed some ---- up though. Thanks for your help guys.

Do a search on here and Honda-Tech for AFC Hack. That would probably be your best bet unless your ECM can be re-programed, I'm not familiar with Chevy ECM's though.

K cool....anything as to what kind of turbo might work the best for my truck? I am a novice at reading alot of these values. Like i said...a turbo with an internal wastegate that allows about 7-8psi is what im looking for...i know that they used to put some sort of mitsubishi turbo on the cyclones and typhoons (suped up gen-I s-trucks) but that was on the 4.3 i beleive...

thanks,

Try looking at old Ford Thunderbird turbos; if I were you I would be looking for a turbo from a car with similar displacement as yours. I think they are gated at 7-8 psi also.

that motor will handle hella more than 8psi and some internal gates are good up to 15psi. For a turbo, it depends on how much you want to spend. Is that motor a 4 or 6 cylinder?
