I read alot about swapin motors but I have a simple question I have 92 civic dx d15b7 4 dr i want to drop in a b16a(sir2) or b18c1
both jdm but which motor is better from a dead stop with there stock trans or should i swap the trans or what plz post your option

[CivicSpoon]

The b18c1 because it has more torque. Stock tranny is good, you could change it out for the Type R tranny that comes with closer gearing and stock LSD. The LSD alone will help you get better traction from a stop.

[wako528]

what if your cruizin which is better

[CivicSpoon]

the stock GS-R one

[wako528]

anyone else

[Ace$nyper]

GSR civicspoon is correct.

[CivicSpoon]

The reason I say get the GS-R tranny is because the early Integra Type R ('96-'97) have the same gear ratio as the B16a and Civic Type R. And the GS-R tranny has slightly higher gearing so you won't have to shift quite as much. The other option is the LS tranny that has the longest gears, but it will suck for acceleration when you're at the track; but be good for cruising and for gas mileage. So I figure go with the one in between (GS-R) for good acceleration and decent gearing for crusing. And it also had an option for LSD as well.

thx civicspoon what if I want to go trubo with would be the best

[GScivic7]

b18b...has most boost friendly compression

[wako528]

b18c1 or b16a(sir2) and why

[GScivic7]

b18C1, it has oil squirters and a block girdle. Makes it a little safer to boost. The best thing to do would use a B18C block with a B16A head. That's basically a poor man's Type R motor there.

[wako528]

should i replace the internals on the b18c1

yes and yes to that.
even though you run less PSI on it it'll make more WHP then a LS boosting at the 2 or so more PSI they can take.

i'm doing poormans type R allmotor cause i'm teh sex.

how much $$$ and what are you goals depend on if you want to replace insides.

5 grand I want 300hp 250tq what about the stock axles u think the can take it

[Ace$nyper]

i'd rather not find outh the hard way with stock axles but i've seen stock guts GSRs push 300WHP before.

god forbid i can find you dnyo graphs to back it up sorry mate.

Tuning thicker headgasket good turbo set up and tuning good exhaust set up.


*i know tuning is listed 2 times thats cause its important enough to repete.*
