not suprised, being auto...my 4294 with a .91 T6 housing wasn't any laggier than a 3540 1.06 on a RB30 single cammer really with a auto

only a split second was a 3540 better and then the 3540 got fiercely trodden on...

The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

agreed that drag+auto = a totally different ball game when it comes to response. its got very little in common with response on a street or circuit car.

have had a 3076 on an old school 4 pot feel as responsive as a T25 SR with the right cam and stall combo. easy to do, just useless around a bend.

I had a 35r on a 6boost mani, I changed to a new 6boost mani and 7175, and it is more responsive In every way, makes more power earlier, power doesnt drop off, and builds boost on the tbrake significantly faster....

Must be moving on from older technology that did it...

Tossing up between a 6262, 6266 and 6466 on a stock capacity RB26... Looking for good response and 400-450rwkw on moderate boost 20-25psi

T4 0.82 divided rear... Want most of the boost all in by 4000rpm

Also is everyone just going journal bearing or running the ball bearing? I don't mind the extra cost if it's worth it

Well after Jez's result on his standard 26, it'll be hard to go past the 6262. He made 402 at just over 20 -21 psi IIRC.

I've seen some photos of the 66mm cea turbine next to their older stuff... I'd be highly tempted as the aero looks great.

Question in my mind is 62 vs 64 compressor in terms of lag. Id be tempted to just go a 6466 for the headroom, coz u know u will end up with a dirty 30 lol

When I was comparing my 6466 to a 6262 a few weeks ago, the angle on the blades looked a little different but also the gap between the blades on the intake were signicantly more of the 6466. Both were CEA's

Hmm thats indicating its more than just a change in trim, the 64mm comp must have a way bigger exducer than the 62mm so its more or less an entirely difference turbo.

Like comparing a 3076 and 3082 I guess. Same stuff, different application entirely.

A link to a page with comparison to old tech 65mm wheel (I think the 62mm turbine is same tech) and compared to new 66 CEA turbine:

FYI both 6262 and 6266 are rated as 700HP items. I'd be chasing that 66 CEA item, better tech is where its at.

Finally got the 5558 in today, can I use any 3" v-band flange off ebay (exhaust/dump side), and what oil line/fitting did you guys use - do I just go to Pirtek/Enzed or get an ebay jobbie - re: Kando lines fit? I am not sure if you just connect the oil line to part way in the existing line or get rid of existing and new one straight to block? thanks :)

      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.
