rb30 bottom end for r32 gtr

[KNG-32R]

my engine is up for a rebuild and just wanted to know is it worth putting an rb30 vl turbo bottom end on my gtr bottom end if so what are the advantages and if not what are the disadvantages

any help would be appreciated

thanks damo

better low down torque and driveability.. allow larger turbos to spool up faster due to increased displacement.

good option to go for if your bottom end is fugged.. go for it

[KNG-32R]

thanks for that

I think you need to find a workshop that has done this. My understanding is that there are substantial differences in the sump that will make this very difficult.

Just rebuild it back to standard, the rb26 can make power OK as it is

is it worth putting an rb30 vl turbo bottom end

Please don't refer to an RB30 block as if it's a Holden product.

A fair run of bad luck there. Spun a bearing or something like that?

if you gt the cash, have the rb30 block put in, and a rb26 head, will never regret it, and will make much more power then standard.

What power figure are you aiming for Damien, what is the car mainly used for, what turbo's will you be using and list any other mods as then the choice will be simple

If you going to race it down the QTR id get the 3.0bottom end off a VL .

but if your going to circuit it etc.. just get the 2.6..

in the end id go for a 3.0ltr bottom end since it has lots more torque.

[BU5TER]

What if its just a road car and he's only looking for around 250awkw, seems to me it wouldn't be worth it unless he's looking for big power and the spool up a 3L will provide on a big turbo

[LaL]

yeh, ahh well id just stick with the 3.0ltr since itd cost you probably a few dollars more

[BU5TER]

Yep great reason

[LaL]

hey buster,

is that you in the photo! hahah ???

i was being carcastic

Ahh ok, well, I was being sarcastic

U might want to check out if the gearbox bellhousing matches the rb30 block and whether the rb26 sump fits as well....

Im not sure abt the specific details but there has to be a reason why we've only seen rb30ed rwd skylines....and the existence of the very expensive os giken stroker kit (with block spacer) to achieve the 3 liters in awd skylines

I have only seen 1 completly successful 3.0 ltr installation into a 33 GTR. by successful i mean makes over 400 rwkw reliably and confidently. sure there are people out there who will take your money, but dont realise that the rb26 sump wont fit on a 3.0 ltr without a major engineering effort. its not a case of 'chuck in a vl block and she will be right mate'

there is great expense, modification and engineering effort required for the extra 400cc.

Put up with a little lag, get a smaller turbs, or fork out up to 30k.
