its your car do whatever you want with it..you can always start out by gettin intake, headers, exhaust for starters..

crazyguy

stock sir 2 and gsr have similar short gears..and both of them have optional LSD

but im not to sure what companies to go with that perform better with the b series. cuz im comming from a Dseries motor...lol just not too sure what I/H/E perform better or what not with a b16a2.

so then they are the same tranny pretty-much? and neither one is better than the other?

Go with your stock SiR tranny, it has the shorter gear ratios that go along with the B16 engine. Dont know why you would pick a GSR tranny, maybe if you wanted a slower car

i run CTR intake cam gsr exhaust cam I/H/E and tune on my b16a2 and i put down like 157 to the wheels

injen sri/greddy header/apexi ws2 with test pipe.

just to give you an idea about power range...

SOHCcivic97

what were the tq gains? any??
so when i change the cams etc.. i can go get it tuned?? and see/feel a nice amount of power out of it.

get an lad tranny....a lil more $$$ but worth it

and my friend put about $1,000 worth of bolt on on his civic and only got around 30hp gain...
but then he spent $300 and got his head ported and polished and ended up with 80 hp gain in the end....

bolt ons are good but think of it this way...if you get a BIG intake manifold, and a nice set of headers....its not going to make a diffrence if the holes in your head are still small oem....

get it ported then work from there

***LSD GSR tranny

SOHCcivic97

so then what would be a good bore size to go with?

justinrl613

well im not sure how much bigger he went....
i know it depends on how much you want to spend....the bigger, the more time it takes, the more money..

take it to your local machine shop and ask what they think.

Your telling him to get a GSR tranny for his B16? What are the benefits for that?

justinrl613

just about the same gear ratio's,
but from experiance the gsr trannys last longer...and are better if you can find one

Gear ratios are not the same, the B16's are shorter which help that torqueless motor. Last longer? I dont think he'll be driving the car for 200K miles all these transmissions have the same reliability. Their not just better, a B16 tranny will be suited best for his motor.

How long have you "driven" a LSD gsr tranny? You must of had it for quite sometime.

I'm gettin a B18 next week if all goes well and I'm gonna stick with skunk2 for most of my bolts on. I haven't looked into any other companies much but skunk2 know what they're doing.
