Re: need some advice (building my motor up)
 

Definately go with 9:1. D series compression calculator put my car at 8.8:1 with vitara pistons, then i had my block decked .026" Turbo spools just where it used to, but i probabaly only dropped a half a point of compression.

jon ever since you turboed your car you havn't been very nice to the nublets

Re: need some advice (building my motor up)
 

Don't ---- around with thick/thin headgaskets if you're buying pistons, you're spending money on this thing, spend it right.

There's no doubt that sleeves/rods/pistons make a good combo for high boost, even just piston and rods are good to 500WHP if you can find someone who knows how to tune. The problem becomes making the rest of your setup work together properly to hit those numbers with some degree of efficiency and thus reliablility.

Re: need some advice (building my motor up)
 

can someone than direct me to where i can find info on building engines? because i thought all u needed were, APR headstuds, some head work to match up with the sleeves, copper headgasket, new darton sleeves, low comp pistons, TT's rods, new main bearings, what else do you need? do i necessarily need to beef up my valvetrain if i am going to stick with the stock redline?

You can leave the head alone if you want. But with a LS being such a shitty flowing head, you probably won't want to. If you want to take it eas at first and do no machine work to the head if it's no neccessary, just do cams and gears. Depending on your cam decides whether you need better retainers and springs. Normally if your not revving higher you won't but if you cam has a HUGE lift you will.

When mine goes under the knife, which is right now, it's getting just some re-grind cams, JG Gears, and a Intake Manifold. I might Port match the head, but I heard toss ups on whether you can do this with the Vavles in or with them out. I don't want to dissassemble my head this far. So if anyone can clear up this please do!

Re: need some advice (building my motor up)
 

I wouldn't say the LS is a "shitty flowing head", but a nice set of cams/springs benefit it nicely in keeping the powerband up in the higher rpms. VTEC is for faggot ricers and people who like a nice idle.

Just copy this guys setup and like Evans says in it, get bigger injectors and a good clutch.

Really, that's all 99% of people do, look at HMT, 90% of the setups are the same, because people see what works and use it. Can you do it all a better way? Probably. Can you do it copying somebody else's setup? Definately.

Ha, a lumpy idle is way nicer then a smooth idle!!

Re: need some advice (building my motor up)
 

Right on

Re: need some advice (building my motor up)
 

Lol, judging by this thread this build is never going to ------- happen. I'd say do some darton sleeves, with a blockguard and some block filler.

Nah, at that level you might as well fill it with cement!!!!

But ya, I sort-of have te same feeling as Whitey
