i would try the forced induction thread you prob get a lot more help

mrharmonic

sounds liike my old b20 lol

Sure you can, you won't be able to run much and you'll need a tuner who's confident at what he does, but it can be done. It's all about where you want your power... if you want more top end you'll have to drop the compression a little.

i would def be careful with that 12.1:1 is really high compression but talk to a really good tuner

D16SiHatch

a thick hg would raise the compression not lower it. do you have any idea what compression you're actually at? how did you come up with 12.1? not to say it can't be done, but it'd be a lot easier to boost and tune it if it were like 9:1 or there abouts.

Deetz

To the OP, with what you have listed there...depending on the HG, your compression should be about 11:1

Not sure where you figure out the higher number from!

K7-1Ktrevor

what? you mean a thick headgasket will lower compression not raise it..

Eviltek1989

the shop that it was done at they had told me that the compression would be around 12.1 i know i sound like a fool but ive always went stock b20b with high boost and a great tune but now i just wanna try somethn else after i threw a rod in my old b20 so thats y i hav no clue wats goin on or wat to do sorry guys and thanx for tryn to help me out tho... so if u say it sounds like its a 11.1 comp i guess thats better for me cuz i was about to go another route and start over but that would be a pain in the *** for me

is this jose?

ask around on nolimit, Javi ran a supercharger on his car.

Jimster480

yes it will because its increasing the size of the compression chamber.

D16SiHatch

yes that is what i meant. it came out bass ackwards lol. it raises how high the cylinder head sits and how much volume is in the combustion chamber though. i think that's how i managed to confuse that lol.

Eviltek1989

i would but i rarely see people with jrsc in reno other than my boys? but there not ls.vtek they are built swaps...whos this tho???

90RENOsedan

its logan. i hangout with robert. used to roll the ef sedan on si's.
you should hit up javier on nolimit. elguapo is his name on there. he had a jrsc on his del sol.
