yes - that is what i was thinking, here is the pic!

this with slotting engine mounts should work.

no harm in trying it!!

RB25 covers won't fit, its a different shape. Thats why RB25 owners go to RB26 covers

how do rb25 engines fit with 26 covers & not the other way around? is there clearance issues with the cams?

[jangles]

you can RB20 covers on a 26 head tho?

that must be it - got my wires crossed AGAIN

[jangles]

i missed out 'fit' now ive re-read it.

RB20 ones go on, so why wouldnt RB25 go on? the top of the cylinder head is the same shape?

so why wouldnt the RB25 fit on a 26, if cams were the issue i wouldnt think the 20 covers would fit.

although, the backing plates and gear covers are different shape

just trollin, but has anyone tried the 20 covers? I know they fit since a mate of mine had them on in his gtr

I've got a 32gtr looking to get a RB30 bottom end, just want to suss out the issues before it all goes ahead

Hi All,

Quick update:

I recently sold my rb2630 engine to a mate of mine who is setting up an R32GTR circuit car (that engine belongs on the track TBH, too angry for the street).

As soon as he sets it up, I’ll report back here with results.

This guy is a demon behind the wheel...used to pull 1:08s around wakefield with a stock gtr running higher boost.

I now have a replacement Bathurst Winner which is piece of history & icon – I bought back my old Australian Delivered R32 GTR

[bubba]

Wow.. cool yet somehow uncool at the same time enjoy the ride!

[Marko R1]

yes it is 'uncool' that i sold my engine BUT the timing was well aligned with the purchase of my aust gtr, it was all by coincidence.

it is however 'cool' that i got my old car back though...here are some pics & 1 of an r35gtr on the way back from picking it up on the day:

[bubba]

So tidy!

Nice one Marko!

[ezy_09s]

Very nice...so damn clean.

[Marko R1]

thanks for the kind comments guys

i'll be treating this gtr with the respect it deserves, like 1 of those passionate/obsessive a9x & phase 3 owners lol

[Simonster]

Very nice looking version!

Hi all,

My rb30dett is now fitted in my mates circuit GTR, this is his 1st outing (reserved driving) & was doing 1:11’s around wakefield. His car still needs sorting around stiff suspension etc. Engine is tuned down to 350awkw on Federal RSR595s on a very cold track. The 280degree cams are too big and power comes in too late for circuit so will swap them out for 264/11mm lift to bring turbos on 1000rpm earlier. With good tyres that will wipe off another 4sec +.

The best time he did with my current gtr was 1:08 on Pirelli full slicks & only 220 awkw! He is a very good driver!

[jnrevo]

Just incase anyone is interested. This car is now running the same set up with 300awkw and 595rsr. It has done 1:09.8 at Wakefield park. There is may be a second or two left to shave if I get better tires and my brake zone correctly.

But all credit to the engine. The -10's with 260 cams work magic. A little lag under 4000rpm. But she turn into a monster after that.

[Marko R1]

U have a great engine there Tuan...I spent a lot of time asking many questions to many people which some can attest to here

The only mechanical changes to the engine is the smaller cams from 280s to 260s, upgrade ecu from power fc to vipec, lower boost and now tuned by unique autosports.

I know this as I sold that engine to a good friend of mine.
