Yes.

Tomei were my start point but I couldn't find a reference to an 86mm piston, only oversize ones.

Didnt look at ACL or Nitto (Not that the NItto list has an 86mm size anyway) because I didnt want to use them.

Have CP pistons currently and given the issues I have dont want to go back there either.

Despite all available evidence being to the contrary I am not a complete idiot. I understand cps reputation. None the less I would still like to establish who makes forged pistons in 86mms because from what I can see it is a much smaller number than for oversized pistons for obvious reasons.

I'm not sure who's insinuating you're an idiot but it's certainly not me! I'd love to know what went wrong though. I've got 2 RB's with forged CP's so keen to know what could potentially go wrong.

Are the slugs going in a brand new engine? The reason I ask is most of our 12-21 year old RB's are pretty much due for re-sizing by the time their due for new pistons.

Sorry for deflecting from your goal!

My quick Google search brought up-

Arias

Wossner (??)

HKS

CP

JE

ACL

Gong Chang (holy crap, the Chinese are on board the forgie train!!)

Apexi

Pretty good choice really..

I would also line to know what went wrong with CP pistons.

I believe that information may be more valuable that the current display of attitude. Particularly to us CP users who have put their hard earned into big builds.

Attitude? FFS.

I said I had engine issues.

I said I didn't want to use CP's again.

I did not say the cause of the issues were the CP pistons or that there was anything wrong with the brand.

Happy?

    • 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.
