Boys wat gearbox am a looking for to fit the vl and rb26 ??? Should I go auto or manual??

Hey boys started ripping the rb30 out of the car today.. Have decided to go 30 bottom end and 26 head ! Forged motor Going for a twin turbo setup Powerglide Fuel setup and maybe a shot of nos ) Want to crack the 9's Going all out! Will post up pics when I got time .. Selling the rb26 block and crank shaft if anyone's interested ?? Some original photos have not been recovered yet.

you dont need a 26 head to run 9's !

Petros ur absolutely right bro , a close mate of mine will be helping with the build and he suggested to go with the 26 head as I already have one from yrs ago that's been sitting in the garage..

I have heard that the rb25 heads fit better with the oil and water galleries and the rb26 head requires drilling into the rb30 or something to make it line up. Is that true???

From memory the rb26 uses 12 mill head bolts as the 30 uses 10 mill so drill and tap would be necessary... The oil drain and water passage is different to it sits in the corner so better speak with the mechanic to figure it out.. Other than that should fit straight up!!

What do u guys suggest on a box for the vl and that can handle good power?

MX7 (http://www.ebay.com.au/itm/Holden-VL...em 35be1c2581 (http://www.ebay.com.au/itm/Holden-VL-Turbo-MX7-Commodore-Gearbox-Reconditoned-/230822782337?pt=AU_Car_Parts_Accessories&hash=item35be1c2581)) or R33 (http://www.ebay.com.au/itm/Nissan-R3...em 35bee8ab0a (http://www.ebay.com.au/itm/Nissan-R33-GTST-Skyline-5-Speed-Manual-Gearbox-Reconditioned-/230836185866?pt=AU_Car_Parts_Accessories&hash=item35bee8ab0a)) The R33 will handle more power. But a few modifications are needed.

Standard rb30 head bolt size are M12X1.75 and rb26 are M14X2.0 iirc. You'll just have to run a tap down the threads no need to drill.

But a few modifications are needed. Thank for ur link bro , I think I might use the standard rb30 box but I'll strip in down and take it to ALS race glides and tell em to trick it up!! That way I know 100% it's going to bolt up to the 30 As I said I'm learning as I'm going and getting info and advise on doing work .. Appreciate ur help bro. ---------- Post added 16-09-12 at 18:03 ---------- Today me and a few of the boys finished off taking the rb30 out was easier than I thought, now it's going to the builder for acid dip and machining then slowly itt will get built.. I'll keep u updated..
