Which block should I start with?

[Deadmoans]

Guys - I'm going to throw my 2cents in.

I had similar problem with my 98 GSX, blew balance shaft bearings.

I did some pretty good research on crank walk. And that is really the debate between 6 and 7 bolt blocks.

Here's what I found out - nobody really knows what causes it. I talked to speed shops across the country - ones that build racers too. The 98 and above 7 bolt is better because they changed the design of the thrust bearings. I also got a lot of negative feedback about the ACT clutches especially the older ones in relation to crank walk.

Check my specs on my car. I did the wiseco pistons +20 and eagle rods and crank, used a centerforce dual friction clutch, new oil pump assembly, stock head ported, 1g intake extrude hone. Had a machine shop hot tank, deck, clean, bore and assembly the engine.

I have the Super 16G turbo rebuilt to an 18G.

I love my set up!!!!

Oh, and to change over a 2g to a 6bolt there are some other small things that have to be converted. I can't remember but there's a web page out there that has a list. Roadraceengineering.com can help too.

I got my parts for my build from Jackson Auto Machine.

You will have to enlarge the head bolt holes in the 2g head to fit the larger 1g head bolts.

yeah, from 11mm to 12mm, i know about the head stud sizes, also need to trim the motor mount braket, one of the cover's corners, etc, i've read the magnus pdf 1gina2g. Havent put any thing in stone yet. Its hard in my area because no one around here wants to work on a Mitsubishi, even tho its a talon , you say mitsu or 4g63 at these shops around here and tell you to junk it, so i have to relie on outside help, like overbore, or Jackson Auto Machine.

Thanks for the input keep them coming.
