Listen to Troy. :domokun:

Having a motor that I spent quite a bit on leaves one worrying that it will break. :blush:

$500 cheap RB20 and then building your rb23 up on the side yourself for cheap is definitely the way to go. So so much more enjoyable.

Pistons - I'm a bit stumped with these atm(and the crank and rods for that matter). Had a quick squizz then, they also have 'UNISIA' and an outline sorta thing of the Nissan symbol.

I'm pretty stubborn when it comes to using jap only parts. Unless there is a clear advantage I would much prefer keeping it all jap. Old bearings look like standard Nissan.

Forced induction is by a full HKS T04e kit. Hence I would rather go with the combination now that will help with response in any way. Labor cost for the entire build is a couple of bottles of bourbon.

Cams - Read through the 'RB26 camshafts in RB20' thread. Aftermarket seems like much less hassle. Will be keeping a look out on Yahoo.

Be aware that that thread talks about using stock rb26 cams in an rb20 engine which no one has proven it to work.

Reground rb26 cams (to suit a hydraulic lifter application) has been proven to work.

Grab a 3071 on the HKS TO4E kit...throw in some Tomei pistons, or if you can wait some custom Cosworth or Arias pistons that are 83mm. Stick with your current bottom end.

Also, dont go too big on the cams. Look at the duration of the RB20 cam to start with...remember its only a 2L. At best grab some baby 256 etc cams and get what increase in lift you can. STD RB20 cams in my experience are no bad thing. Bigger cams may help, but my experience was that it took more fiddling then your new 17yr old girlfriend to get decent action from :thumbsup:

Match porting and cleaning up std gear is cheaper and possibly the better route.

Cheap RB20 has been acquired! Makes alot more sense to research and slowly build the 23/24. Maybe I'm stupid but now I'm kinda looking forward to no boost below 4k.

Power Enterprises F1 Black metal bearings sound good?

Reground RB26 cams I will have to look into further.

After seeing a pic of GTR pistons I'm certain the ones removed from the stroker are stock Nissan. Why Nissan would release pistons in that size I don't know.

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      Yeah, that's when. I guess you could say I'm as patient as I am foolish(or just a masochist?🤔). I've strongly considered throwing in the towel and calling it all quits many times, and have almost done so. It's a first-world problem for sure, but I've had a pretty rough go of it, as well as other factors; hoping something good comes of all this; it has to. It definitely is half the price of the ATS and performs great, but I'd like to try something different for once. I've sampled the ATS in a friend's 32 and it's solid👍

      I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!
