i want to do a b18b swap on my civic. i looking for like 400hp i getting arp head studs, darton sleeves, cp pistons and eagle rods, crower stage two turbo cams, 750cc injectors, walbro 255lph fuel pump, and i was thinking a gt3076r but idk if that will spool up fast enough what would spool up fast and still make 400 hp

 

Whats your budget?

 

1500 for the turbo i budgeting everything out seperatly i got all the parts i listed except the turbo

 

lol sleeves?

 

holset hw40 will do the job. seriously sleeves for a 400hp? ditch the 402-t2 for 404 you will be happier.

 

i ordered darton mid wet sleeves i sending my block to a local engine shop to have them put in

 

i putting in sleeves to be on the safe side so i know that wont be a failure point

 

holset hw40 what rpm will that start to build boost
also will a t70t3 spool fast it says it will support up to 500hp

 

If its 1500 for just the turbo then I'd look into the GT30 or GT35, or like go journal bearing which is cheaper and get a 60trim. The sleeves is good insurance, I mean if he had a goal of 300whp it would overkill, cause he would eventually get sick of it and turn up boost maybe then have 400. But starting with 400 when he turns it up hes allready built for 500+. Most people would just throw a B16/B18 vtec head and see better gains then cams alone. There are a lot of LSVtecs with stock heads making big power. The holsets are hard to come by in good condition (ive looked) and there kinda expensive to rebuild.

 

about what rpm would the gt30 start to build boost bc i really hopeing for something that starts to build at like 3500 or 4000rpm
and i thought bout ls vtec but i think ill just stay non vtec be different than all the ppl i personally know with built hondas

 

It would be closer to 4000rpms on a straight LS. Its a good turbo to use for this goal

 

what valves and springs would be good to go with for this power goal and higher

 

The cams are going to the be the "kicker" (A set of Crower 404s should do it), but otherwise, Supertech, Skunk2, Portflow, for valvetrain will work. Changing the valves themselves will not be necessary.

 

precision 5431E will work perfect for spool and make more than your power goal

 

another q what ecu should i use for this build

 

what trans would i use for this build that would be cable clutch. i heard longer gears were good if you have a turbo engine, so i was thinking about a trans from a b18a. but then i was told by a friend to us a b16 trans. so idk what i should use, any thoughts?

 

try both and make up you mind...i did. but most say gsr trans is better
