hey guys,i got b20 vtec on my integra n i got hondata s200 that still lock so i cant pass 4000rpm. Im switching it to hodata s300 so it will tune better(after i change this hondata, can it go all the wat to 9000rpm?). so wat the cheapes way to get my car up to 230 to 250 whp (i want all motor)?? pls help me out here. oh i need jdm lip for my car.

 

you most likely have a distributor problem that doesn't allow you to rev past four. Any cels?

 

cels??? well i just buy s300 hondata so it will tune well. i have s200 on it now buy is still lock so i just figure it will b better if i have a newer one so it will tune well n easy.

 

wat

 

if you type in english with proper spelling and grammer we might be able to help you out.

 

What have you done to the motor? any upgrade on the head and block. Its pointless if the motor is stock and you want it to rev to 9,000rpm.

 

yup stock b20 and 9k = boom

 

alright. well the engine is still stock. all i have done to it is put in a s300 hondata. (that was a mistake cause i'm sure my s200 will work just fine.) and also i'm going to put in stage 2 camshafts. do i have to rebuild the head to go up to 9000 rpm?

 

Yes.

 

It never stop's. Use common sence. Does any B series head in stock form rev that high safely? NO

 

so from this point what do i have to do to make the engine to go up to 230 or 250 whp? with out turbo?

 

the S3 wont make a differnece if you still cant go past 4k rpm. either have a dizzy problem or teh ecu is just no good. i had the same problem before and it threw a code about dizzy not firing correctly, but after i switched ECU's, it ran fine again. so try a different ecu first before replacing the dizzy

 

yup get your car running right before swapping cams, tune etc. etc.
if you want a fast car that never runs right, buy a dsm.

 

haha... im not in a hurry to make my car all fast. i still have alot to learn about b20 vtec. i use to have talon tsi, the engine blew on me. im just going to take this one nice n slow.

 

Read the FAQ that is stickied at the top of the forum. There are several B20VTEC build ups in there in the 230-250hp range to give you an idea of what it takes to make that kind of power. If you dont have any parts right now, be prepared to drop around$5-6k.
