Everyone who is running lsvtec in their car i would like to know what compression you are running.I had an lsvtec with pr3 b16a pistons in it but want to go for higher compression. however i don't want to run on race gas because its my daily driver.Im in the process of building another lsvtec and would like your input on what to get.

 

Mine is not complete yet, but I had the pr3 pistons before I switch to .25ITR slugs.
pr3 net about 11.4:1
p73 net about 11.1:1

over bore will add slight bumps but not much. I've been told the pr3 slugs aren't good for high altitude because of the compression, unless you use race octane. But other wise 93 is good on the street.
Hope that gave you some answers.


Oh yeah, the next step up is CTR or aftermarket, but not streetable.

So you swiched out to lower compression?What setup do you have and what kind of numbers are you putting out?

 

It's not done yet. I keep running into funds problems. Almost done though. I only switched to ITR slugs because my cylinders had an oval in them. So it got bored.

I have b18a block
pr3 head
gsr tranny(not sure on code)
other misc crap.
p28 ecu with DOHC mugen program
I have some pr3 slugs for sale if anybody wants them. along with the rods too.


I saw a dyno chart of an ls/vtec
HIgh compression, gsr head, stock ecu and ctr cams-208hp, 141lb-ft at wheels

anyone

 

In a nutshell I have a b16 head with ITR pistons in a B18a block with b18b rods the head is milled 40 thou and I cannot race without 100+ octane gas. I retard the timing and run 270cc injectors with a custom Ericks racing PR3 ECU and I can drive around town but I don't dare jump on the throttle. I guess it can be a good thing less speeding tickets.
