I’ve got my car – a Civic B18C1 in the shop right now getting parts fitted. The guys there are having a real problem getting the car to idle without screwing the adjustment up the stops and say it now runs worse than standard. Since they have put on several parts at once they don’t know where to start to find a problem and aren’t prepared to waste valuable time playing around until they know what to check. They are a well known race shop and have set up my chassis very nicely but are not true Honda specialists.

The engine has a standard bottom end and head, the CAI is an AEMV2, the throttle body is a 65mm Edelbrock, the inlet manifold is Skunk2, the cams wheels, retainers and springs are also skunk2, the cam is a Pro race stage1. There is also an adjustable fuel pressure regulator fitted and a full Supersprint manifold 4-2-1 and cat by pass system. All the gaskets and head bolts were replaced with new genuine Honda standard parts, the ECU is also standard - All that remains to go on is the Apexi AFC Neo.

I had hoped that this set up would take the engine from its standard 170bhp to ITR figures and still be street drivable with a good top end pull but apparently the mechanic describes it as flat as a pancake!!

To get my car back in a drivable state I need to give them an idea of what to change, adjust or throw away!

Will getting the NEO on help cure any fuel issues or have I chosen a load of crap parts which I’ll have to sell on ebay and go back to standard!!!

Experienced help or advice would be much appreciated. Otherwise any short cut to a similar, previous post is a plan B

 

I havent seen a car that has aftermarket cams and idles like shit.
i'd put the stock cams on if you have em

 

you need something better than a vafc to tune with

 

So... when you took it in there did it run ok? If not, remove/revert what was done... seems kinda obvious to me. :dunno:

 

if the cams are agressive you're idle is bound to suck. the cams are probably stage 3's and meant for track use, IE not just sitting around idleing, but making powe till 11k

 

the guys doing the work for me are falkland performance who are well known in scotland. they have a rolling road on site so i had thought the skill and equipment was there to complete the job.

all the parts should be a straight forward bolt on but its causing a lot of head scratching and they had the car in for the past 5 days.

prior to going in only the CAI and exhaust system where fitted, the car ran fine and felt quick but I want a bigger kick out of it without going forced induction or getting a re-mortgage

i'll check out more info on the pro 1 cams set up, all i know is the intake has a 12.6 lift at 1mm and a duration of 264, the exhaust is 11.9 and 264

 

sounds like you need to tune it. you need something programmable like hondata to tune with. a vafc wont get the job done. it's probably falling flat on its face cause vtec is way too low for those cams.
