B16A in CRX '88 running slow any ideas?

[skiiboy90]

Hey Guys,

I recently purchased a CRX Gen II 88 with a b16a engine swap.

I have been told that the engine came out of a 98 civic vti, so i was wondering what type of b16a do i have and how much kw/hp should it have?

i looked on the engine, it simply says 'b16a' not a2 or anything like that.

Also, i have an apexi vtec controller, but i get the feeling it isnt tuned right, as the car is getting molested by my mates dc2 vtir. My crx is completly stripped, and we both know how to drive. I should be walking away yeah?

Any reason why my car would be running so slow...what should i check out and fix to isolate the issues?

Many thanks,

skiiboy90.

whats actually happening??? is vtec engaging? theyre a pretty quick motor
and being in a CRX you shouldnt be getting left too far behind if anything at all...

i suggest either removing the vtec controller as theyre basically pointless unless
your hardcore worked and/or see the track at least once a month...

Get I/H/E done all so perhaps??

check compressions
check plugs
check leads
check timing
use only PREMIUM fuel i.e V-Power, Caltex Vortex, BP Ultimate...

im interested in this topic as a mate of mine has a b16 but aus spec A2 but it doesnt pull it hit vtec on first switch but after that it feels the same...... and it revs up to 9400 but is useless, ive checked the ecu.. its a standard ecu...

get rid of vtec controller and check out plugs do service etc and check for cel codes (cel codes in crx is on passenger side under the carpet jst pull it bak if theres codes should be blinking then jst check it out on the diy section its a sticky should find the problem .

Standard ECU with a revcut at 9400 lol?

yes i know very weird aye?

[string]

Real rev limit is probably 8500 or 8700; I don't think it's too far fetched to say the stock tacho could be out by 5-10%.

Check your plugs, base timing, all the usual "tune-up" things.

compression test it.

What dose the Block serial number start with?

Cable clutch?

Build dates stamped on the head anyway

I have the SiR ll out of an 93 EG6 170hp/125kw and she feels very punchy

Hydro clutch
Block Serial start with 5xxxx
Transmission: S4C

Ready this http://hybrid.honda-perf.org/tech/b16a/

And for gods sack loose the VTec controller!!! Honda knows exactly where the VTec crossover point should be...

[skiiboy90]

if i get the vtec controller profesionally tuned, will it be better than the stock ecu guys?

very good link

if the engine is internally stock,ie no big cams,head work,compression changes,etc,then the best place for the vtec xover point is where the stock ecu will do it in any case.

the vtec controller setting/wiring,etc could be causing the problems u describe,so the first thing i would be doing is taking it out to eliminate that as a possible fault.

if engine is stock,u dont need it & really shouldnt have it anywhere near your car if u value it.
