I drive a b20vtec 89 hatch and i now want to go turbo. I am working on a 93 rx-7 at the same time so money it tight. I am wantin to know what is the best way you make 300whp without building the bottom end. I need the whole set up please, fuel, electrical, which turbo ect. anything will help. The civic will be my daily driver. Something to play around town in.

 

300hp only? i don't know much about the sleeves of the b20, but i know LS can handle 300hp stock block. just need a decent size injectors like 550s or even 440s, hondata ecu programming, and a stronger fuel pump, fuel pressure regulator. a t3/t4 turbo can handle that power, get a good manifold not like spark or some weak sauce ****. there's more but i don't know for sure, i'm learning how to tune in a month or so i'll tell you more, because my goal is 350hp also, undecided engine for my eg.

 

**** for 300, just buy like a drag kit and run uberdata or the hack. 300whp isnt **** compared to what most want you could make that easy with the t3/t4 that comes with the kit. I dont think you could make it with the fmu and stock injectors but you could try.

I haven't seen too many people making 300whp with the hack or uberdata...not dissing them but i personally haven't seen the dyno's..

Ive seen plenty of people make over 300 with the hack. With Uberdata you definitely could as long as you tune it on the dyno and burn the chip there

 

ya, only 300whp, i have a 93 rx-7 and looking for 500whp out of it. The civic is my everyday toy

 

t3t/t4 turbos can give u over 100hp on low boost settings, so with a b20vtec = 200+100.. easy.

 

and this is with stock bottom end? The head is ported and polished all ready with type r cams. Would that be enough.

 

stock bottom end is risky....

 

even with hondata? I though it would be ok. I really don't want to spend the money on a build up right now, but at the same time i don't want to blow the motor.

 

you can make 300hp with a stock bottom end easily

 

i have always heard that the b20s have the weakest sleaves out of the b series.

Exactly what I was thinking.

You can't just say oh, b20vtec 200hp and turbo 100hp more.
