Hi guys, need some advice, i just recently got my skyline through a good friend of mine. Problem i am running into is bad boost creep as the revs go up. I put a manual boost controller on to see if it would help to maintain it but no luck, and it plays around with the ecu as it try to adjust so it getting slow spots through the rev range. If i put the standard solenoid back on, will it sturdy the boost as it was designed to do, or is there another issue, i have checked for boost leaks and replaces lines, but still the same. The line running the wastegate is one that the charcoal canister usually runs too. any help would be great on the topic

Thanks

Josh

Get a decent boost source.

teeing a line from the evap canister is not a good way to control boost, and is most likely the source of your problem.

Use the nipple off the compressor housing or get a hose barb welded into your intercooler piping.

I didnt realise the stock turbos had a nipple?

What kind of dump pipe do you have?

If its a splt dump, it could be the issue. I had alot of problems with boost creep on my R33 with the split design. Even after having it ground down and fixed with the old wategate flapper issue. I put the stock one back on and it went away immediately.

Ended up having a custom bellmouth style made up instead and its still fine.

Do you lose much power by putting the stock one back on, and what's the bellmouth one, how is it different. Still new to turbo car. This is the setup that came on the car. I'm not bothered about running standard boost, I would put standard solenoid on if I new it would work, or ebc.

check out just jap here, youll be better off getting a 3" bellmouth then going back to the standard item. also a good ebc helps aswell, i am a big fan of the jaycar item its cheap and has some great reviews.

    • 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.
