BAAAAAAHAHAHAHA! :D Just wondering if the T66 might surge making 50psi @ 3000? Maybe I should put a bigger exhaust on to increase lag say something silly like a 3.5" system and bring the turbo on around 1000rpm later? ;)

dont be a top bloke, get a t70, cause that one comes with the compressor maps! cause new turbos suck! why pay all that money on a fancy engine and shit and not get an old turbo!

I think a lot of what people are trying to communicate here is that for a large percentage of people looking at engines.

Just spending a bit of cash on building a 26 is probably more cost effective than an RB28 or 30.

Don't let anyone tell you having a properly running and installed thirty is a walk in the park or cheaper... it's simply not the case.

People also tend to harp on about a few issues in the Skyline world purely because they are the uneducated consensus.

I think a lot of people would be a lot better off if they thought of it purely in terms of the block box theory.

A black box where air and fuel goes in and work comes out.

I don't know of I'm missing something, but I have absolutely no idea what you are getting at with the black box theory ??

When I take the car for a spin this week Ill let you know. Or better yet come down and drive it for yourself, afterwards you can sit down with Bob and tell him how he could improve the combo.

Not sure if anyone has mentioned what car this is going in???

After doing a RB2630 in a R34 GTR, I would say don't do it if it is going into a 4wd, especially if you want to go dry sump in the future. Bonnet didn't fit, sway bar fouls the dry sump fittings, block adapter means bottom gearbox holes are now out by 40mm, inter cooler pipes need to lengthened, exhaust needs to be lengthened, strut brace doesn't fit, clutch master doesn't fit anymore... The list goes on and on...

If you build a 3ltr, build it as a 3.2ltr.

Also, a RB2630 does rev, mine will go to 9000... And has survived a few 10,000 over revs.

If you want something easy build a 2.8 cause everything bolts back up, but if your willing to put in the work a 3L is a great thing

like what I said here on the first page about the 3l needing extra work to fit.

I don't know how your bell housing bolts ended up out by 40mm mine were out by 10mm (little bit of customizing and now they fit) and my sump is no where near hitting my sway bar and my standard clutch master is still in the car

Sorry, bolts out by 10mm... There still out and require fab work to modify. My sump doesn't foul on the sway bar, the external oil pump fittings do (dry sump). Clutch master doesn't fit due to the Greddy intake plenum that used to fit fine. Add to that the cross member needed to be notched, the firewall taken to with a hammer etc etc.

    • I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp
    • Forgot to mention that these are the before pics when I first got it!
    • Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆
    • Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
