i have a stock b20 motor just got it with less than 60,000 miles i want to swap it into a 91 civic si hatchback. i want to know what is everything i need to turbo it, what type of piston, rods, ect. basicly i want the b20 to handle atleast 30psi. anybody let me know pls and thanks.

check out the k20 forums on hybrid-racing.com . basically similar, theres quite a bit of people on there and they sell all the stuff you'd need for the swap.

he has a bseries motor not a K and they are not similiar at all. K-cost 6k plus for a complete swap. He can swap his b less then 1k.

What year is the b20?
basic list...
chipped p28 or whatever ecu you have I can't remember.
axles, bseries tranny ls,gsr,itr,ctr,si plenty of opitions, convert everything to obd1 so you'll need a new dizzy modified wiring harness, also motor mounts for the b to fit in the civic. Hasport makes a good kit/ thats just some basics. Google it plenty of info out there, if you have any more questions ask.

turbo
ic piping, ic, bov,manifold,turbo, wg.

you will not ever get 30psi don't even shoot for that. You know nothing about honda's start at 7psi. No one is going to spoon feed you there secrets on a honda motor to hold that much psi. You talking about 30k plus in a honda motor/turbo/tranny to even hold that much. Plus setting up your civic to even hold the power its going to make.

you do not need to convert to obd1. and you do not need a p28 because a stock b20 isnt vtec. you will need an integra ls intake manifold. you can use the ls distributor as well to run obdo.

read what I said chipped p28 or whatever you have. Even if he has a p28 vtec ecu can be turned off in the tune. And not convert to obd1 I didn't say he did, its adviced. There are plenty of tunning software for 0bd1 cars thats why people convert.

Would you rather him run a [censored]ty FMU and his car still runs like [censored]?
