ok i need to know a couple things and i know im gunna sound like a tard but what is the difference between 6bolt and 7bolt, besides the notorious crank walking in the 2g 6bolt. plus will a 6bolt head mount up to a 7bolt block. what all am i going to need to do a 1g swap? this is going to be my first 4g63 so im clueless here. someone help me out.

i believe the 6 bolt has better oil squiters

2g 4g63 are not 6 bolt, they all are 7. 1g heads will work on a 7 bolt block, but they are not a direct bolt on, i believe the holes for the studs have to be opened up or changed. compression is different, head and intake manifolds are different, 2gs manifolds, o2 housings, and throttle body elbows flow better stock than 1gs. No cas on 2gs? i believe. someone who likes 2gs chime in. lol, these are some of the things. theres a writeup somewhere about all the differences.

heres whats needed for the swap...

"What is a 6-bolt engine?
What is a 7-bolt engine?



A 6-bolt engine is one that has a 6-bolt flywheel - that is, there are 6 bolts holding the flywheel to the crankshaft. A 7-bolt motor has 7 bolts there.

Along with the flywheel change, there are many other internal changes between the two engines. The crankshafts are different sizes, as are the rods and crankshaft seals. 6-bolt motors have 'big' rods, while 7-bolt engines have 'small' rods. The journal and bearing widths different, although the bearing diameters are the same. There may also be other changes between the two engines, and the parts are not interchangeable. "
I got that from vfaq.com

ok so what engine do i want. i know it has to be a 1g but 6 bolt or 7 bolt?

1g 6 bolt

EclipseGuy

how much should i expect to spend on it and would do i need to buy a 1g tranny aswell or can i still use a 2g tranny?

EclipseGuy

oh and i was reading about the oil lifters on the 1g and seems the lifters on the 2g have larger ports. can i use the 2g lifters in the 1g motor?

7 bolt engines are better .......... btw 6 bolts can crankwalk too

JR.
