hey all, my r32 with rb20DET is getting harder to start, i have to pump the accelerator to get it to start, when its warm its fine, any ideas? btw plugs have been regapped to 0.8, ive got a fmic, HKS evc, apart from that its stock as a rock.

theres a cold start valve on the r33. i think the 32 has one, and its easier to access. that could be your problem. it opens up to allow more air to the intake until it gets warm, then shuts.

if your idle is steady once started, i would assume your aac valve is working ok.

well thats what i thought lol, guess it just needs more air??, had a knock sensor trouble code and it just sounds normal when starting, cant really describe any odd sounds, just my fuel pump turning on and it cranking lol

really???? most cold start setups are richer.

check that the TPS is setup correctly

hold on. do you mean pump your accelerator before cranking it? or when you start it, it needs gas to bring the revs up or it stalls?

hey mate my car has being doing this. If i don't pick the revs up to about 1500rpm as soon as I start it it will stall any ideas what is causeing this only happens when the car is cold.

Just a thought, but could it be over fuelling? maybe almost flooding of sorts. I know whenever I rejetted a carby & went too far I would have to hold throttle open-not an efi I know but you have changed the amount of fuel going in it may be messing with cold start map

Ive had this problem with my 32 and my main factor was the afm ( air flow metre ). Its running good now besides from the pumping of the gas when car is on, try the AAC valve, give it a clean, its located at the back of the plenum near the firewall kinda, cant miss it.

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
