Hey ppl,

Ok heres the scenario, I took the turbo's and all associated pipework connections off my engine on my R32 GTR to get completely rebuilt, steel wheels etc. That has been done so now its time to put everything back together. First question, is the exhaust manifolds different front to rear? I know the dump pipes are different. Without knowing if the manifold/turbo combination is apparent I bolted both turbo's up to manifolds and dumps. Installed rear turbo then front and all associated oil/coolant lines, then the exh front pipes. When it came time to install the intercooler pipe between turbo's (bit with TWIN TURBO on it) they dont meet up properly. As in the pipe at the rear is about 20mm too close to the rocker cover as in bends up from the turbo. Second question, are they turbo's aligned differently? My thoughts are, i've put the wrong turbo on front to rear, or ive put the wrong exh manifold on front to rear or Both. The other is the rear turbo compressor housing was not put back together in the same alignment. When looking at it from the front of the car, the rear intercooler outlet on the turbo is about 10mm closer to the block than the front. Thus making the pipework not meet up. SO, does any one know if the turbo's and manifolds are different front to rear. The manifolds do have markings on the top of them. Any help or input is greatly appreciated..

5 mins spent marking things is 5 hrs work saved

I know :D i marked everything else! dump pipes, inlet, i/cooler, oil/coolant lines but forget or just thought the turbos and manifolds were identical. Oh well, better get undoing everything again. Hope the new tomei exh manifold gasket didn't get too 'crushed' so I can use it again..

manifolds are different, turbos are the same.

R33 GTR manifolds are exactly the same as each other.....are you sure the R32's are different ?

I had exactly this problem on my GTR turbos after re-building them. I just needed to re-allign the compressor housings slightly in relation to each other.

Problem was fixed, rear turbo compressor housing just had to be rotated around a little..A lot of effort taking them damn turbo's off again dammit :) oh well..the cars back going again after a few months which im very very happy for.

    • 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.
