hey an ls vtec with 250 fuily built and tunned with high compression pistons forged for nitrous and on c16 gas how long you think it would last sleeved of course compression high 12.5:1-13.1. idk i meant get forged 11.5:1 pistons

 

well first off 250whp is a LOT harder to do than you might thing...unless you meant AFTER the nitrous. That has a LOT to do with prosepected life.

if you run nitrous EVERYDAY....you're gonna have a considerabbly shorter engine life span.... If you turn the car to 9000+ daily, you're gonna have a considerably shorter life span.....and if you aren't tuned properly, you'll bave a VERY short enigne life span.

it's all about the tuning and the way you drive. Drive with sense and you'll be fine for about 40-50k miles. drive like you're in a race car everywhere you go and it'll probally be much less than half that.

but seein as you're saying it's on C16, i can only assume this IS, in fact, a race engine and NOT a street engine. There's no point in running that compression on the street, anyways. SO it'll come down to the tune...you could last a whole season of weekly racing with it......just take care of it and keep the tune up to date with whatever conditions you're facing and you should be good to do for several hundred race miles.

 

thanks the engine priced it as cost me sadley is around 10g and not really a daily driver but im doing drag races at night

 

cant i get even a few more thouseand miles if i change the bearings every month?

 

To make 250 all motor, you are going to end up with cams that are way to big for nitrous.

 

yes i know but i can overlap the out with tunning, jun 3 cams...im not even useing longer than a sec or 2

heres my setup
b16 Dh-racing head Port and Poilsh
-ericking racing 68mm throttle body
-ib spec dual springs
-ferra valves
-ferra retainers
-ferra rocker arms
-jun 3 cams
-toda cam gears
-arp head bolts

-je or wiesco ? high compression pistons

-hondata

what compression should i use to use nitrous but it still has to be high and im be on c16 fully tunned

 

bump cause im reatard y0!

 

Get A Portflow Head...

 

2nd that.. GET anyother head but the DH-Racing head.. Portflow would be a good choice..

 

whats wrong with the dh head?

 

There is nothing wrong with high compresion and nitrous.

And the big cam wasting nitrous thing is overrated.

If this is track only and C16 only go 13:1 and hit it with a 100 shot direct port. You will be fine if tuned with a dedicated system.

I will have a 100 shot DP on my 12:1 85mm LSVTEC very soon.

 

how do i tune the lift oiut?

 

You can't tune lift out. Lift is a physical paremeter of your cam.

You can tune cam overlap out by adjusting your cam gears. If you retard the intake and advance the exhaust you will reduce valve opening overlap.

 

thanks thats what i was asking

 

bump

 

bump to the top

 

morning bump

 

bump

 

i guess you will just have to try it and report back. its not a question anyone can truly answer. there is to many variables. good luck

 

ok i guess so thanks guys....
