any reasons why exactly you recomend the 40s? im just interested to learn any advantages behind them

 

^^^ The larger the diameter of the pistons, the more displacement the engine has. More displacement=more air flow=more power. You will be able to spool up a big turbo faster with more displacement as well.

Check out importperformanceparts.net for pauter rods, wiseco pistons, ferrea valvetrain components and all other engine build necessities.

 

i would think 40 over vs 20 over vs stock bore would be like so little you wouldnt notice

 

.20 over is great. it gives little change to strength, and it opens up the combustion chamber a little more. .40 over is too much in my opinion unless you are using a thick walled block. What compression ratio are you shooting for. Also a stoker kit would be great for the number you want.

 

^^^This is a solid decked block!

All you people saying that .040 is too big, have you actually done it on a Beta? Thought not.

 

jon,

I know you more about engine building than i do but is .040" over really needed for a daily driver?

well, haha, neither is 500WHP, but that is another topic.from hearing everything about 600 to 900 whp cars over in korea I really wonder just how many of them are drove to the grocery store or to work on a daily basis.

 

ill check that site and have been looking into the stroker kit a little. im thinking about writing rpw about it.
i think the wisecos are 8.8:1 if i remember right. is there any better pistons?

 

Ya same here.I have had Weisco 20 overbore and paurter Rods for about 2 years and no problems..Make sure you take it to a good machine shop that does this to ensure a good job.
After a few runs when you install it do a compression test and make sure you have high numbers smile.gif
I got about 195 psi across all 4 cylinders

 

what about the crank guys? it is in really great shape but do you recomend doing anything to make the motor stronger as far as the crank?

 

If you plan on going past 6,500rpm's. I would get the crank balanced, and possible cryotreated.
