i have a 95 gsr with a b20 block & b16 head, And down low lots of torque, but in vtec its really not pulling how it should, Ive raced si's and pulled by 3 lengths at the start then had them almost pass me, its not the way i shift, i often take it to 8k when i race, people are telling me its because i need headers & intake mani, both are b16 as of now think it would be improve alot with headers/intake manifold ? any other suggestions ?

 

a properly built b20/b16 combo pulls all the way to redline.

 

fuel?

 

did you break in the motor correctly? fuel?

 

is that like downgrading parts?

from b18 heads to b16?

isny downnngrading always bad?

 

are you running the stock compression? high end power is laced with high compression and the B20 block doesnt have either (unless built)

 

no a b16 head has a better top end.....better for the b20 setup

 

not necessarily true. a B16 is better with higher lift cams, especially if its if its ported and polished. take a look here

I'm having the same problem. I have a jdm b20b/b17. b16a and b17 shared the same head, just different cams. My car's absolutely a dog at high end, but it might be my LS tranny or it might the PS, AC, and ABS.

a vtec tranny is a must when dealing with fully built all motor setup. the ls tranny's longer gears will take longer for ur engine to reach the higher rpms where the vtec head shines.

 

good god man! lose that LS tranny. your car will haul once u get a b16 or ITR tranny

 

People tell me i should get an ITR Intake Manifold, what do you think ?

 

as of now its b16

 

what other mods are on your car? have you had it dyno tuned? what kind of tranny are you running?

 

no other mods, havent had it dyno'd & b16 tranny

 

the PS, AC, and ABS shouldn't have that much effect on your top end.

 

get a VAFC and then some dyno tuning. try importbuilders in fullerton.

 

ok thanks, but for the time being could anything bad come out of buying the itr intake mani ? i know where i can get a really good deal on one

 

nothing bad could happen...but it would be wise to rectify the problem first before adding different upgrades.

 

yea thats true, alright thanks, dyno's are around 70-80 bucks on average right ?

 

yes but more with tuning. give importbuilders a call and explain the situation, theyll give you a price.

 

go ahead and get the ITR mani. its cheaper than the skunk one and its pretty much the same

 

here are a few pics, there are a few things that could really use some replacin, but right now the funds arent exactly rollin in, maybe this will give you guys a better idea

 

try to get rid of the stock header first. that's really choking ur setup right now.

 

oh c'mon! You're telling him the solution to the problem is getting a header or a new tranny? The problem is your fuel curve is way off. You need to go to the dyno!
