ur on the right track

 

ok, i just went to zealworks and used b16b pistons and it said ill have a 14.2 compression ratio. wont my motor blow fast?

 

what kinda of compression am i shooting for?

 

arp rod bolts.. shot peen the rods.. balance balance balance

 

I'm lead to believe that those are some pretty high compression pistons in that setup. You may want to get something a little smaller or go get some way bigger cams, a good intake manifold, some big injectors and plan on running race gas all the time. But other than that you sound like you're on the right track. As said before balance balance balance lol. Rod bolts are a must if your are sticking with stock rods. I don't know how important shotpeening is in your case. I've heard the stock rods hold pretty good power. But better safe than sorry.

 

14.2:1 is on the right track?????????no way to much compression. im not using race gas so if i bump it down to b16a pistons my compression drops to 13:1. will i be safe on 94 octane?

I would probably be shooting for no more than 11.5:1. It would run good on pump gas without having to retard the timing so much you won't make power.

 

im going to shoot for 12:1 and get a good tune larger injectors.

who makes an ls/vtec headgasket for a 81.5mm bore? all i can find is 81mm

 

I think the mr. gasket ones are 82 and 84.

 

I'm running 12.7:1 compression on my ls/vtec 93 octane, daily driven, putting down 186 whp, its all in the tuning~

 

would you go 13:1 with 450cc injectors? and a professional tune? on 93 octance that is?

What are you talking about 93 octane is plenty good gas for my compression, you know the old muscle cars, the reason they made such high numbers is because they had high compression ratios, 13:1 compression can easily be done on the street with pump gas.

i dunno man that seems pretty high. it looks like most people are running around 11.5:1 on 93 octane

</TD></TR></TABLE>What old muscle cars are you talking about? the 500hp limited edition corvettes that ran 12:5:1 but had to run 100+ octane and still had detonation problems? Given the fact that they had cast iron heads and were carbureted. But that's not what I'm talking about. I'm talking about junk gas we have today meaning you have to run 11.8:1 AFR and 30 degrees of timing just so this 13:1 motor runs ok. That's a lot of lost horsepower. But I'm not gonna argue with you anymore.

I don't wish to argue, i will admit i dont know a whole lot in the tuning area, i just know that my motor is running 12.7:1 compression on pump gas, the motor runs strong, and don't have any knocking problems, and it put down really good numbers, so i know its possible.

 

shot peening is cheap.. and a really good idea..chains only as strong as the weakest link..

 

everything looks good.. But while you have the motor out, i'd suggest getting the rods shot peened, get some ARP rod bolts as well. and have the crank micropolish and balanced, its worth the extra money for the reliability.

and 13.1 compression can run off pumped gas, but you have to get it tuned real good.. I have a family friend who's runing about 13.1 in his built B20vtec. he uses pump gas (the highest octane we have around here is 91 some places have 92.. no 93).. his car is tuned real good. hes been running it for the last 2 years..

I've seen other people run 13.1 on pump gas.. its all in the tuning.
