Im start to plan my rb26dett build an would like to get some input on what i was thinking for the build. I have a 98 R33 rb26dett motor and want to do a full build on it. ill be building it in two stages and dont want to do any thing twice. what im looking for is 650 to 700HP and 9000rpm and as much response as possible this motor will be in a custom car im building from the ground up check out my other thread for the car build. THE TOP END I was thinking Brian crower 1mm over sized valves, BC stage 2 cams, BC valve springs,BC keepers,BC valve guid Greddy intake manifold, injector dynamics 1000cc. Tomei turbo manifolds, custom dump tubes 3" GARRETT GT2860r 5, all greddy piping and intake piping, the head will get a stage 1 port job and port match everything, as well as clean up the oil returns. Greddy timing belt, Mines cam Baffle plate, head drain kit

i dont think ull get 650-700hp out of 2860r -5s, im running them with ported manifold, ported head, stock intake manifold and greddy piping on 22psi and am getting 485hp at wheels.

With e85 and larger exhausts i would get about 550-600max on 25psi i was told.

Only a stage 1 port job? Dude, there'll be danger to the manifold with a stage 1 at over 9000!!! RPM.

Use the search.

how do you mean danger to the manifold ? i haven't heard of a good rb26 head porter that i would trust that lives with in 500 mile of me plus in my experience head porting is a art and very few are really good at it plus is it really worth 2 or 3 thousand dollers to get a little more power out of your motor when you can just turn the boost up a few pounds

Can be done, but it takes alot of coin to get there.

Nah. 150hp shot of NOS. It'd be easy.

You can probably get a package deal for some NOS and stage 2 cams.

And delivered overnight!

What are stage 2 cams?

It is possible with -5's but I'd rather go a hta 3586r and save on the head porting and just give it a tidy up.

Cheers Josh.

Well people are mercilessly taking the piss for the F&F style reference to those & the head works but they are supposedly these..

i don't mind going with a little bigger turbo but I'm trying to keep it as responsive as possible i might just have to see how much power i get out of the -5s and if I don't get 650 HP or so ill try the GT2871r-10 just afraid i would have to much lag. O and the cost yeah its a lot Ill pry be right at $28,000.00 US all said and done

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
