i've only been boosting about a month now and i already have a slight problem. I recently did another compression test on my ls and it came up 125, 170, 170, 165. I havn't been pinging the rev limiter but i'm sure my friends have so i'm guessing i probably have a bent valve. I figure if i'm gonna fix that and if the head is already off, should i just do a ls/vtec conversion or modify the current head for better flow. Save some money on some machine work and head gasket i guess...

Current setup:
-my own built kit with a revhard mani and t3/t4 turbo
-38mm tial pushin .5 bar (no boost controller yet...)
-fmu, walbro 255 fuel pump (was saving up for hondata w/boost but...head first)
-3" all the way back

Engine: stock ls with about 100k on it [i've been the only owner, i baby it but my friends beat it up ]

Goals:
-eh...nothing high. 250whp with reliability(does this mean no ls/vtec turbo?).

if i do go ls/vtec, i got a really nice moroso valve cover for sale!

 

BUMP...any advice is good. specially from the Expertz ;P

 

Everyone is going to tell you to go w/ the VTEC head but, I am a non-vtec lover so, NON-VTEC all the way .

Relaibility is in the hands of the builder and tuner in either situation. If you don't want to spend a ton of money just get the valve(s) fixed and 250 WHP should be a realistic goal w/ your current setup.

I respect the ls(had 2 ls turbos). Before I joined this site I thought you can get high horsepower with only vtec. I see doing all that machine work to the head probably end up costing me more than a vtec head. Which teh vtec heads are already good flowing from the factory.

 

thanx for your input, but hmm...vtec or no vtec?

 

yes it would be better with the vtec head
