Are you talking killowatts? What on earth are you going to do with 580kw @ the wheels??

"Drag Me" runs a RB25 at around 520kw @ wheels with nitrous if i remember correctly and im pretty sure it still runs a standard block (obviously with extremely strong internals) with just some extra oil squitters. So with that stroker kit and a massive turbo and a engine worked to an inch of it's life.....yeah its possible. Hope you can afford to sell both of your kidneys and maybe a friends kidney.

Once again.....what on earth are you going to do with 580kw??

Tomei 2.8 litre stroker.

Same kit for both RB25 and Rb26 motors

77.7 mm stroke

119.5 mm rods

either 86.5/87/87/5 mm pistons with either non cooling or cooling channel pistons.

I've never been able to find out the true use of the cooling channel pistons?

Well In my car, R33 GTR with the Tomei stroker kit with NON cooling channel pistons running GT-RS's at 1.6 bar and ive never had a problem. It was built by another member off this forum who happens to be a very close mate of mine. So unless you looking for over what the RS's can produce power wise I cant see you needing them. The car to date has run a 11.2 @ 130 MPH so it aint no slug!

Is this used for race work? like longer circuit work?

It's primarily a street car but i did take it to wakefield once. Ran without any problems at all, even after 25 laps @ 1.6 Bar and oil temps reaching 120 degrees.

Motor has been built with 2 thou clearences.

if you want that much power (im going to assume its hp) go for a local 3 litre bottom end. shit load more toqure for every day driving, probly cheaper to build than a tomei kit, and more reliable IMO than an RB26 (25/26 whatever you wanna call it)

yeh its hp not kilowatts. 3lt bottom end with 25 head i wont do bcuz there is alot of mucking around that i would have to do with manifold to intercooler pipe heights and exhaust height cuz the 30 block is slighty taller well it sat higher in my mates gtr when he had a 3026 with a t51r. plus the fact of im lazy and dont wanna do ne other work then wats needed lol. and cheaper not where i live buddy, there is one machine shop and one engine builder and hes mainly based on v8's he abit of a dick to he doesnt like to set-up rb25 heads bcuz they take to much time boo hoo if ya gettin payed wat does it matter lol.... and i also want to be able to rev my car to 8500 and not have to worry my arse off about the bottom flying apart the tomei kit is a very strong combo from wat ive seen from certain cars like top rpm which revs to 9000....

    • I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.
    • The old approach was to fill the cylinder/chamber with a length of rope pushed in through the sparkplug hole. The new approach is to connect compressed air to the sparkplug hole and fill it with enough pressure to push the valves up. Doing either of these things with the head on and the engine in the car is a lot less pleasant than doing it properly.
    • Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?
    • One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching
    • Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.
