If your in no hurry i would have a look for already built engines can be cheaper but you dont know what your gettn for sure

[daveR32gtr]

yeah thats 1 of the things 2 member....any info on where 2 get a decent engine from?

[blind_elk]

If the engine is not very healthy, then the car is worth virtually nothing. So not really any point selling it.

If it's broken a ring, you should stop driving it, otherwise you risk scoring the bore beyond repair.

Check out the advertisers in Zoom! / HPI for a straight up replacement engine. Maybe then you can rebuild this one a bit later, and as you can afford various bits for it.

[MerlinTheHapyPig]

i would suggest rebuilding, as it's probably cheaper than a new engine - also you take a risk that new engine is just as bad!

If it was a ca18 or rb20, probably not worth rebuilding, but an rb26 is worth it.

rebuild with excellent fruit will cost you under 10k... turbos a couple more maybe and you walk away with 350awkw.

That turns a bad situation into a very good one

[Sambo33]

ive gone the full rebuild, forged pistons ect, price will be under 6K with a 12 month guarantee. i was thinking of a second-hand low km engine, but you get virtually no warranty on those.

[Race__24]

I'd get the engine out and apart so you can see what you're dealing with, then go from there. I wouldn't think it would be worth selling.

I saw a R33 GTR Series-II engine at Powerplay in Sydney here for 8.5k. Thats how much it cost me to rebuild mine after broken ringlands and scored bores. But I did opt for Forged pistons and getting the bottom end blueprinted and balanced. Sad thing is it didnt actually go any better when I got it back

[al_r33]

daveR32gtr, I live in Hobart and I just had the exact problem except that Bo. 5, 6 were leaking 90%. I just got it back after it was rebuilt with forged piston, rods all the good stuff plus they fully reconditioned my motor! It cost me 8k but that was everything including a big clutch and fuel pump. I got Griffiths Automotive to do it and I was very happy with them knowing that it was done properly and right the first time! I probably gained an extra 20-40% power on what I had! And I am very impressed with the car now.

if you got any questions then just PM me.

cheers

daveR32gtr: I saw a modified R32 GTR engine at Just Jap in Sydney on the weekend that has HKS turbos, aftermarket cams and a fair bit more. I think they wanted $9kish for it.

Might be worth sending them an email

the rebuild would not have attained that though... power mods you must have done at the same time would have.

*cough* RB30 bottom end *cough*

[SeriesIIGTST]

I'm also of the rebuild opinion. When I bought my car (admittedly only a GTST) I never planned on big HP or swapping turbos or anything. Long story short, No 6 ring lands went for thier own tour and left me with your choices - rebuild or 2nd hand motor. Figuring that the 2nd hand motor could end up with yet another rebuild, i went the rebuild the first time around, replaced some OEM stuff with some fancier stuff - forged pistons, balanced crank, etc, without going over the top. Car now runs sensationally. No problems and I love it to pieces. Don't sell.

DR GTR is selling a r34 GTR motor for about 7k its in the trading post at the moment .

[daveR32gtr]

[daveR32gtr]

oh gtst what do u mean rb30 bottom end...(i am a newbie sorry) pretty sure i know... just wanna get feed back on what it is..whats involved is it worth it ...expensive etc ..ta

[wrxhoon]

The other option is a new Nismo engine ( complete long engine ) from Japan for $8-9 k then you can sell yours for $2-2.5 k .

[Duncan]

:werd:

or if you want to sell it just throw a second hand one in there and off load it, then sell your busted engine

well there is a whole thread above called R33 RB30det conversion.

but the jist of it..

you get a NON turbo VL commodore rb30DE bottom end for $100.

spend some dosh (lets say $3K) to put in forged pistons and rods.

stick your RB26det head on it.

get a 4wd sump adapter from one of the guys on this forum.

once sorted, you basically have a rb26dett with a 3L bottom end.

when you have a day or 2 spare, have a read through the 108 pages of that thread above..

it is pretty much all interesting..
