Rb30 Crank In Rb26 Block

[WA_R32]

Hey, i was wondering if it is at all possible or if anyone has already done this?

I have been doing some research and thought that using the RB26 block would have its advantages like the added strength as well as not fouling on the bonnet.

any ideas would be great

cheers

You would need a spacer between block and head or you will punch the pistons right through the head.

I believe that's the way they do it in Japan ala OSGiken 3L with custom crank/rods/pistons.

Note the deck spacer and sleeves

Yeah i also noticed the $31,000 US pricetag

just looking at different options at the moment, the vg30 has a shorter stroke and also custom pistons could be made to suit, i read somewhere that someone de-stroked the crank to 2.9 ltrs and put it together like that

um....wat?

The VG30 is a V6

sorry, only meant the rods from the vg30 not the crank

[zebra]

ahh right...gotya.

SR20 rods have been used with a custom crank to make a 2.9L RB

[WA_R32]

hmm didn't want to go for a custom crank, too $$$$$$$

might have to stick with just the normal 26/30 then

Apexi used to make a 2.9L stroker kit for the RB26. Good luck finding one though

(RRP was 1.4 million Yen ~ $20K AUD)

[zebra]

Racespec also have one...well 2.85L anyway

I have heard a rumour it has been done. Would love to know if its true or not

If $$$ are an issue then why recreate the wheel?

because the wheel is gay, i would prefer and oval wheel or something like that

[NXTIME]

Oh, the Apexi 2.9L kit retains the standard height block - no spacer or liners.

A custom crank is about $6K.

or get a 30 block and stoke that to 3.3...?

[N1GTR]

Custom crank $5-6000

Custom pistons $1500

Custom rods (good ones) $1900

Waiting months and months when you couldve done a 3.0L, priceless.

If the racespec ones are in stock that would be a different story. One thing though, i dont like how they use 87.5mm bore.

Gold!

When Spools 3.4L kits become available (and if I have fundage) I'll start to build a 3.4L on the side to go into the skyline and the stag can have the current 30.

that would be sweet, hmmm have decided to just stick with the 30/26 been done before and dont want to fck something up trying to make my own hybrid engine

hmm now i have a complete rb26 bottom end to sell as well as a brand new R34 Nur Spec front diff and sump, any takers?

[bubba]

What's the deal with the sump? if it's fancy enough I could probably talk Mikey into it

it wont fit in a 32 will only fit in a 33gtr or 34gtr, the 32 is too narrow for it to fit in, i got it with my engine as the person who sold it to me couldnt use it on his 32

[bubba]

Ahh well that screws that idea then
