[Warriors1994]

Ok I have a second gen 4g63 and had a 1 gen gave to me are there any differences? And will the first gen work in my 98? if so what do I need to change

If the motor you got has the turbo on it, the 14b, put it on the 2 g, and have a fun daily

Alright killer since you haven't explored the almighty Google yet, i will drop a quick compare and contrast for you.

1g's 90-93 1/2 ................. 2G's 93 1/2-99

Stronger rods .................... Stronger pistons
Stronger bottom ends .................... Arguably better heads
Better turbos .................... Better Sensors
Arguably bigger Fuel Rails ................... Better coil packs
Adjustable CAS ( advance/retard timing) ................
Bigger intake manifold ports ...............

"for the most part everything is interchangeable with or with out modifications.

My suggestion rip out the 1g 6bolt tear it down and build that bad boy up (with your choice of either gen head) and get it ready either for your 1g body or 2g body. and Bud dont shy from using un-measurable power of your search engine !!

I'm laughing at myself because I was just gonna say that I thought that the 2g fuel rail was bigger. Then I see that you put arguably before it.
