VTEC Problem after a full engine rebuild. HELP needed please. Thanks.

[danny_2132]

Hey guys

I've just recently rebuilt my 1998 integra vtir with a b18c2 engine.

Whilst doing the rebuild I have add the following modifications:
-Blox b series cams
-Blox Valve springs
-Skunk2 intake manifold
-Skunk2 adjustable cam pulleys'
-Full head service
-New bearings, piston rings

I ran it in for a few hundred kms, and tonight I taught I'd like to finally hear the new crossover rip.

So I've revved it up slowly in first gear and when it crosses over I hear a very loud crossover but there is no power going to my wheels and the crossover sounds like the cams are spinning but there is no power.

Would any of you know what could be the problem? I am thinking it could be timing the cam gears and timing belt.

Thanks.



arite so lately ive replaceed the dizzy bushes, and it has gone more quiet but there was still a rattle,

found the rattle from the bottom end again,,, :(

pulled out the bearings from the bottom end,,, one of them are chewed abit,,,, :(

have you checked your clutch? it could be slipping

[danny_2132]

yer im sure its not the clutch because its under a year old, im hoping its the timing belt and timing, checking it tomorrow...

[xntrik]

maybe vtec isn't all you though it would be :P

tuned? checked your ecu?

[Super-DA9]

have you engaged it in second? third? maybe the difference isn't as significant in first?

lol i dunno just chipping in for ideas. :)

[danny_2132]

yep tired second and third... same deal makes a cross over and no power :(

[joe.teg]

i had the same problem when i did my head. i did the same mods with almost the same parts except i used blox cam gears. when i hit vtec it felt like the car was loosing power, almost like it was bogging down. is this the same problem as you? if it is, give the car a few more runs as the ecu needs to adjust to the extra load of air and dump more fuel into the motor to compensate. once you get the car tuned the problem will go away. is the car an R or VTiR

[aaronng]

What ECU are you running? You can't just change cams and use the same stock ECU. You need a programmable ECU and a tuner to tune it.

[danny_2132]

Hey its a stock ecu... So will my ecu adjust to the current setup after a ffew runs?

[danny_2132]

Ay joe yer ive seen ur setup im mates with peter larsen,,goes to ur uni...

[VTECMACHINE]

Hey its a stock ecu... So will my ecu adjust to the current setup after a ffew runs?

Definately not!

[danny_2132]

ahk thanks. umm so for the new tune will i need a hondata? could you set me out some options? thanks.

[aznstyler]

Try resetting your ECU for now

[danny_2132]

yer already retryed still has the same problem...

or mabi i didnt reset it properly... i removed two fuses from the top left hand side of the box, left it for a bit then put them back in... and plus my batttery on my car was off for like two weeks so wouldnt it have reset when i put it all back together?

[RandyRhydah]

just get a stand alone ecu... or swap heads with me

[danny_2132]

can you help me out, do i go hondata or other?

[GSi_PSi]

you need to tune it , sounds like my cousins b20 when he first dropped it in, with no tune

[danny_2132]

can you suggest me some places i can go to? or what ecu to use... etc thanks.

or im just going to go hondata s300...

thanks

More likely you are LOOSING power everywhere dude. Because your camshafts are allowing more air for longer there needs to be more fuel and timing adjustment etc etc. You need an tuneable ECU to benefit

[RandyRhydah]

hondata / power fc / neptune / anything like that will do.. i picked up a mint power fc with hand controller for 600 bucks on ebay.. just keep searching you will find a bargain.

[dc2r-0636]

power fc is old now but still very good and reasonable price !

[VTECMACHINE]

Get bigger injectors, fuel pump, and a Power FC. PFC are good bang for buck standalone ECUs.

[danny_2132]

ahk thanks ill do some research on pfc's.

guess ill just let it wear in for now...

[VTECMACHINE]

You just built a brand new engine, and want to just let it be for now?

[joe.teg]

hahahaha na mate i dont go to uni, im an apprentice mechanic but yeah you will need a hondata either s100 or s300 as they dont make the s200 anymore. but imo the s100 is good if your not gonna use data logging etc. im running s100 and its awsome for what im using the car for :D

[danny_2132]

well i just spent around 5k, i go to uni and work, i think you can see my problem in throwing another 3-4k to work on it...

its gona be a few weeks before it gets done....

ahk ill look into that... thanks do you know anyone that tunes them and where i can pick up a s100?

cheers

If you are in Sydney, give Adrian at Toda Au a call. He is a dealer on this forum: http://www.ozhonda.com/forum/forumdisplay.php?69-TODA-Performance-Australia-Pty-Ltd
Best to call him and discuss over the phone.

[joe.teg]

i agree with aaronng

[GSi_PSi]

didnt the engine builder advise you to tune the car with a tuneable computer

[danny_2132]

na he didnt :(

pulling out the engine again 2moz :(
