ok i bought a 98 rs 420 with a spun bearing so the motor is all apart i want to know how i should build for around 15 psi what piston cams exc the more info the better

i'm not trying to be a dick but asking questions like this will get you OWNED around here bro. every person that replies to this thread will tell you exactly the same thing...search. this site contains all the info you need but you have to go find it yourself. good luck...chris

just search like 2.4 said...
there are over 100 threads relating on how to rebuild and get ready for high boost.

My friend, we have 5+ years of info stored on this sight in 10's of thousnds of posts. You simply cannot come on here and ask us what you should do. we will not help you in that regard, you need to search and LEARN for yourself. if you get stuck on something then thats a different story, but to just ask a generic "what do i need" post wil ge tyou flamed. If we wanted to build cars for other people we would open up a shop and make money!!!!

Search and learn!

what makes this worse is this is his first post!!! this thread should be deleted or locked.

SEARCH!!!!!!!!

It's all about the cheese. The cheese, man, the cheese.

mmmmmm cheese :9

i did search after every thing i read i can find any thing about the top end i lower i going to do with 8:8:1 forged piston get the block 20 over all bearing exc what about for cams i cant find any thing on them

wow, the biggest freakin thread ever in the advanced tuning section is all about cams, its like 130 posts long, try that

check 'Advanced Tuning' section, or the 'Turbo/Nitrous' section. Plenty of info there. But as far as a quick answer, lots of people have said that the stock cams are good for a turbo in low-boost, Crower twos seem to be good for mid boost range (7-12), and higher boost levels like Crower 3's or the similiar Cranes (I forget which). Top-end is PT lifters and lash adjusters, aftermarket srings (stiffer), 1mm or 2mm oversized STAINLESS STEEL valves, port and polish it, I don't think there's too much secret to it.

No. There is far too much overlap in those cams for a boosted application. Not all aftermarket camsd play well with a turbo application, whereas the stock cams always play nice. For the money, the stock cams will get you very, very far.
