Ha ha. All done!!!! YAY!!!

Finished off all the little crappy stuff in the engine bay and under the car then at 4:30pm finally ran it on the starter to get oil flowing. Could hear every cylinder, nice.

Then started it for real, fired into life after 3 seconds : )

Drove to the servo and loaded it up on the way there and back, with the waste gates free so no boost to help bed in rings.

Came back, dropped the oil and put more mineral oil in and changed filter and hooked waste gate rods back up. Went for another drive, nice! Good to be driving her again.

Only problem may be that I need a new idle control valve :( as the engine revs (flares) by itself continuously at idle.

Sounds throatier than before too.

Thanks :(. In the end I think I owe myself 5K+ lol. Great experience, and knowing the fact you built it yourself!

Well, on the stock bottom end it was putting out 350RWKW on 17psi. So I'd be happy with the same amount (read 500hp atw). Mainly due to he stock gearbox, and I built it to handle the power reliably without worrying about what the bottom end is like.

Went for a drive tonight, and it's really smooth and sounds gutsy lol. I'm only taking it to 4500 to 5000 at the moment at part throttle. Put 110k on it lol.

I'll book it in for a tune once it's got some kays under the belt........we'll see.

great work sean!

looks nice. and i love ur display pic. car looks smooooth as!

cant wait to see the dyno results. sounds promising!

Cheers. They really like taking your money lol.

Unplug it. Need to meet up for a cruz soon when i get my car back.

I'll try it out Brad. I also need to make another dummy load for the hicas solenoid I pulled out of the engine bay to stop the computer thinking theres a fault.

Cruise, for sure. I'll do the Putty cruise in October now :banana:.

Damn Sean, very nice and very fast work - fkn great effort!!

going to bug you for a ride in it soon if i get a night out i'll bring the SLR and take some shots!

Thanks Chris. The engine covers you did for me look awsome with the polished stuff so kudos to you. When we get a chance (read time off from busy schedule) for sure.

unreal sean. ive booked the gtr in for tune weekend after the long weekend at uni group. so will all have to go for cruise very soon. i just need front bumper now!!!!!!!!!!!

I'm glad it's done. Now done over 200k, and it's smooth as. Will be great when you get yours tuned.

I'd also like to thank everyone who gave some advice and imput on how to go about doing this project. 3 months seemed forever to me but it was pretty quick in the end.

Okay! Put 1200km on it so far, changed oil and filter again at 1000k and check up and tune on dyno is booked for tomorrow morning (only good thing about shift work lol). Gonna check a/f ratios etc, to make sure it's happy when I use the upper end of the rev range :P .

It has a pretty beaty, cammy idle, only using 12psi to be safe lol. I guess I'll have to check nuts and bolts are tight too etc. Twin plate clutch is great compared to the triple I had for the street.

Also the engine has no slap or rattles when started and warming up. Engine builder I took the block and pistons to, recommended running piston to bore clearance at 3.5thou so I'm happy.

Congratulation Sean..

Amazing how quick the build was done mate specially with work space..

Looking forward to updates.

Cheers :(

Okay, got it dynoed and cleaned up this morning. Found a couple of things. The fuel reg might need changing as it's a bit sus when revs are high at full load, more fuel was added to compensate but not too bad as it's on min 11 PSI boost anyway. Ordered in one from nissan. It idles at 1400RPM, idle control valve is letting too much air through(o ring inside is non existant), and I cleaned the throttles :D even though I read a topic about not to do that years ago!! It takes the sealing coating off the inside of the butterfly to bore seal.

Other than that, all good and since cam timing is sweet the gaph is great. It'll go back to the dyno in 2000km to get a high boost tune lol.

      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.
