Upgrades for 4g63t

Ok my buddy is parting out his 1997 eclipse GST and he is giving me any parts that will fit my 1990 GST. So i was woundering what parts off the car can i use as a upgrade to my motor. Im not sure what works i know the tb elbow. And please no "the whole motor is an upgrade or turbo" nothing stupid like that.

Ha ha, actually the 2g motor is a definate down grade from your 6 bolt. This is kinda hard to answer not knowing what his mods are, but if it were me, I would take his exhaust manifold, o2 sensor housing, 2g MAF with filter and hard pipe if he has all that, any aftermarket guages, MBC, aftermarket FPR, and aftermarket BOV if he has it.

The only mod it has is full turbo back dual exauts Im probably going to get that. I just thought that some intake parts of exaust parts flowed better on a 2g.

Yup, the 2g exhaust mani and o2 sensor housing are much better than 1g shit, but I doubt that exhuast will work. IIRC, the exhaust exits different sides 1g to 2g. The intake side of things is far inferior on the 2g. If you ever get a chance look at a stock 2g intake mani compared to a stock 1g. Huge difference.

Oh yeah, you should try to make clearer titles for your threads. "4g63t upgrades" is vague as hell for what you are asking.
