Hey all. Have a NEO 25DE head going on a 30 block. Looking at buying a Plazaman intake. The plenum i'm looking at is the "top half" that bolts onto the factory runners.

Is there a difference in the design of the manifold/runners? I am guessing that this plenum would bolt onto both. Can anyone confirm please?

Thanks Chris

i have not got one here to compare though.

Ps the KU plenums from ebay are quite good too (used a few now with excellent results), might save you some coin. :)

Interesting. Guess i might shoot over to the rb30 forum and see what others have done before.

Talking to the bloke from plazmaman, and he says that most people buy a set of turbo runners and bolt them on.

I just had to buy a whole turbo Neo motor to get this guy the proper head. The original head I sent him came out of a non-turbo R34 4 door. I thought it would be the same from information I read on this website. That information was wrong.

I notice that in that thread there was a reference to casting numbers on the heads themselves. Dont suppose you ever worked out which casting fitted which manifold at all?

Got a feeling i am up for an expensive and rather shithouse custom job now...

We are still working that out right now. I've got a head packed up and ready to ship as soon as we find out. I think I might wind up sending him the intake gasket to see if it fits.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      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?

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      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.
