I have a 92 DA with an xsi b16 swap. I recently put CTR cams, Tru-time cam gears and dual exhaust springs in my motor. Now I'm having some very strange problems. I have had it tuned, its runs strong all the way to 9k. Then as I was leaving the shop, I punch it and vtec would hit and sputer out starting at 5.5(where its set) and it sometimes wont even hit or should i say sputer until like 6k-7.5k rpms.

I have already checked my timing, i have reset cam gears to 0 degrees, i have checked valve adjustments, check the plugs and wires, check that the dizzy was ok, and made sure i maintain fuel pressure through the pulls on the dyno.

I am now buying a .16 thickness head gasket and head studs to hopefully solve this puzzle.

I am at wits end here, any suggesting would be appreciated.

sorry far asking but is XSI the AWD one? if not correct me please

 

VTEC sputtering can be cause by low oil

 

now by sputtering do meen like a missfire kinda feeling? like you give it full throttle and it jerks a bit

yea, i couldnt have said it better.

well i got a .030" mls cometic head gasket and arp head studs, so i hope a lil boost of the compression will help.

 

heres another question

does anyone know what the compression difference between and XSI b16a and a CTR b16b?

That might help a lil to know those numbers

 

The XSi is just a second gen b16 that came in the DA Integras over on Japan. Basically a second gen b16 with a cable tranny stock.

The CTR b16b has more aggressive cams, a slightly ported head, and revs higher. It is OBD-2, and came in the Japanese only Civic Type R.

this same thing happend to my car on my way to my boys ( 1bad-eg) house turned out to be the ignitor in the distributor.

exactly. thats why i was asking if it was missfiring. because i had a bad connection to my igniter and it did the same thing. go to g2ic.com and in teg tips they tell you how to fix it.

 

so the ignitor would cause the on again off again vtec?

 

anyone else got any other explainations?

 

well not necessarily vtec, it just starts doing it at a certain rpm. mine did it at 5500 or around there.

mine isnt happening at the same rpm everytime, its very random to be honest. the first pull i can go through 4th w/o any problems, then the next i could sputter at 6k(without vtec hitting), then the next is could hit vtec at my set cross over then sputter one second later

i just wanted to clear that up b/c it seems like you think that this is occuring ONLY at a certain rpm.......mines not

 

there is a filter where the oil enters the VTEC thing (i dont remember what its called but its on the head) that enables the secondary lobes, if this filter is clogged or there is soemthign in it it would cause sputtering

 

BUMP

Now that would prevent VTEC engaging altogether. VTEC is either on or off. No inbetween. It can't kick in harder, or with more or less power all at once, unless the tune is bad. It can't half way kick in either. Its definitely a tuning problem, or ignition problem. I can almost guarantee that the filter is not the problem.

EDIT: I almost forgot... I mis-read the question earlier about the compression between the b16a, and b16b. I thought he meant the difference between the motor, and I totally didn't see he was asking for the compression difference. According to hmotorsonline.com, the second gen b16 (XSi) has 10.4:1, and the CTR b16b has 10.8:1. I also checked c-speedraing's compression calculator, and it says that the b16b has 10.8:1 compression.

 

well i swapped out dizzys today, no change, that rules out the ignitor in the dizzy as the problem. i also checked the 2 screens on the vtec soleniod, both are clear and working. i checked the see if the soleniod was still good as well by grounding it and giving it power to hear it click and stay clicked until it lost the power.

now i really dont know WTF is going on. i really dont think that the tune is whats going on with it because i was there when the car was tuned and it pulled fine on the dyno.

what the flip.........

 

I was having a problem with my misfiring/bogging down while I was in VTEC and it turned out the fule pressure was to high, but seeing as how you just got it tuned you shouldn't have that problem but worth checking.

 

well i got the new head gasket in last night, now my compression should be 10.8

same problem though, i think im going to put the stock cam gears back on and see if that has any affect on things.

this is really pissing me off.....

 

bump

 

Are you sure your ecu is hooked up correctly? I had the same problem you did, and come to find out my ecu was hooked up incorrectly by the last person that owned it. Rewired the pins(a B16 in a civic dx) and it worked perfectly.

Do you have a check engine light or anything like that on?
