Ok. I am doing some things to my engine and was curious if anyone else has done this and what the results were. Ok first of all before anyone asks its out of a 2000 civic SI and it is all factory. Its going with heavier valve springs/retainers, bored to 81.5mm with no sleeves, PC forged pistons, eagle connecting rods, turbonetics T3/T4 hybrid turbo kit, 550cc injectors, stage 3 ACT 4 puck clutch kit, stock cams, stock crank, head studs, copper head gasket, 3 inch spoon sports exhaust w/ resignator instead of cat, driveshaftshop lvl 2.9 axles, obd II - obd I conversion harness with a chipped and tuned obd I ecu. Thats all i can thinnk of for now but just ask if you can think of anything i may have left out.

Thanks

Forgot we also have installed an OBX LSD in a GSR tranny for it

What information are you asking for exactly? If someone has the exact same build as you and what their dyno looked like? Too many variables, you didnt even say what car its in, what psi you plan to use, it could vary from the tune, you didnt mention the compression ratio nothin. Just put it together and let us know how it goes and dont ask people to guess what your setup is gonna produce.

You're forgetting the catalytic converter. It's a needed part.

Also, why not go with a JDM B16 lsd trans? The obx lsd isnt that great from what i've heard. I also hate my GSR trans...and that's with a B18C1. I would much rather have my JDM B16 trans that was...on...my JDM B16


edit: nevermind, i see that you're going with boost. Ignore the transmission part, then.

Im going to run about 15 psi of boost. My tuner said i should easily get 350HP which is my goal. Sorry for not being specific ive just heard some things about unsleeved blocks and was just wondering if anyone had any problems with them. I know i cant run too much boost with it but i plan on getting a sleeved block, probably a b18 gsr or ls and make an ls vtec and use my head on either one. Again i appologize for not being specific.

ghettoSi

It wont need to be sleeved if your only going to run that much boost

A B16 Tranny is definitely the way to go.. The OBX LSD isn't all that great unless you rebuild it.. The ratios on the GSR Tranny aren't as nice as the final in the B16.. Only a 18.5mm bore is okay with stock sleeves.. And you better get a real good tune

you should be cool with those pistons, but in the end it's all in the tune

orangecivicsi

sweet, my tuner is good. Im still waiting on my engine though but when its done ill post some pics of it.

mikeycivic

you can go as high as 500 whp on no sleeves. I am building itr block with 81.5mm bore and shooting for 400+

orangecivicsi

sweet but the gas around here is only at 91 octane and race gas is hard too come by around here.
