i was wondering what the highest compression i could run with using premimum gas i am planning to do je pistons 11.9:1 compression eagle rods and an eagle crank.. then a little later on i am planing to do skunk 2 stage 2 cams, valves, springs, retainers, and prob cam gears and an intake manifold i was wondering if that set up would be good to run off of pump gas. i know regular woulndnt cut it cause it would detonate but do you think super would be good for a daily driver with out detionation thanks,

oh yeah its a 98 gsr swap too i forgot to add that

 

You should be good on premium and 11.9 with some light tuning for ignition timing. With the cams, you will lose some of that compression, so you should be fine. Just get something to tune the car with, though. You'll most likely also have to run a little richer. Get some 440s and maybe an EMS or E-manage (preferrably EMS). Or at the least, get some dyno and wideband time and a VAFC.

 

you should be good...people with 12:1 compressiong run 91 octane with no problems...

why not do the head work first???thats where all the power comes from..

Block has got to hold, winding to 10k means nothing if you throw a rod .

but then again...s2s2 cams dont make power up to 10k do they??? no they dont...so theres no point in reving that high...

you build a block first cause its better so when you wanna up your head, its easier. and you should be okay with 11.9 compression. you really dont need a new crank also, your stock crank should be fine. just go the cheap way and save money. just get itr or b16 pistons and use your stock rods and stock crank with arp rod bolts. and dont use a vafc, there are way better tuning software like crome and hondata

 

it would make it easier but not needed since he really isnt going really big with his setup...theres alot of people that have bigger builds with stock bottom end...take a look...

yeah look on there and my chart is on pg 4. it was for my old 1.8 ls vtec on 91 octane daily driven. basically a comnplet oem bottom end. dont really need anything crazy to make good power

exactly....and with his headwork that he's doing, no need to spend the money on the crank and rods...he aint even gonna rev to 9krpm cause theres no power there...unless he wants to blow..

nice #'s BTW...im plannin on sending my stuff to redzone as well...

Stock bottom end with some arp rod bolts will hold just fine for a street car like the OP is trying to build. I have a good friend that has a gsr with pct pistons (approx 13:1) and some arp rod bolts in his stock rods. It revs to 9400rpm daily, and its been around for almost 2 years now with no issues.

BTW: 96gsrhatch8230, that ~13:1 motor runs on pump gas with no detonating issues either. You will be fine with 11.9:1 compression as long as you have a reputable tuner to tune your car
