1g head on a 2g motor

[abelpescado]

hello ther guys, ive looked around but havent found my answer.

I need to replace the head on my car, and i was wondering if a 1st gen head would fit on a 2nd gen motor.

if it does, would it bolt straight on or would i have to do some work to it? if it doesnt work, does anybody know where i can get a 2g head for a good price? thanks for the help

The heads will interchange, however the 1G head will not work in place of a '95/'96 head where the CAS bolts to the head behind the cam gear.

Read all you need to know here.

Use the Search, this is definitely covered.
You can use it but not without modifications. There will be some wiring to do as well as the head bolts/studs are different sizes between the two as well as intake ports are different sizes requiring a 1g intake

i can be done but it's not simple replacement ...

RRE has a detailed how to on their site
RRE's Eclipse 2g Turbo to 1g Head Swap Tips

i am in the process of doing this myself (i bought the car with it already but incorrectly)

Its well worth the work. 1g intake ports are massive compared to a 2g.

Well what are your goals for the car 1st before you set off on this adventure of swapping the head? If you are not planning just to make the car an all out drag car i would leave the 2g head on there. That was my plan at first to make massive amounts of power but now the goals for my car have changed so now I have done what i could without having to switch the heads again to keep lots of low end power and tq
