bolt pattern...

i have a 1991 eclipse gs...what are all the bolt pattern specs? also, i bought my 2.0 eclipse car used, and it has a turbo, and I know the guy didnt do any engine swaps, but the backend emblem says GS. It doesnt say gs-t, just "gs", with the "16 valve turbo" emblem right next to it. everyone i talk to sees the gs emblem and tell me that its not a turbo, until they look under the hood.. I can plainly see the stock turbo and all the stock parts. whats goin on? thanks lol

The GS-T as a model wasnt introduced until the 2Gs. All FWD turbo 1gs are just called a GS Turbo. Yours is a stock 1g FWD turbo.
