R33 Rb26 Into 89 Z31

[pauls]

I've lined up an r33 rb26dett with ecu & loom & r34gtt manual gbox.

I believe both motor & box are pull so no probs matching them up

Modified RWD sump & custom tail shaft.

Considering r32 ecu & nistune for tuning.

This is going into my z31.

Any recommendations or things to avoid - lookout for ?

Cheers, Paul

Just google "RB26 into Z31" and you'll get lots of hits including a u tube clip of Toshi's RB26DETT powered Z31

Thanks, have looked at all the sites a little too much and know it can be done.

Was seeking insights on any particular things I should be aware/ look out for regarding the rb26dett or mating if up with the GTT r34 box.

Use bolts

Bolts? I was thinking blu tac!

There's a few pics floating around and a heap of BS chit chat, but no actual detailed rb26 build threads anywhere that I can find.

Would have been nice to know specific nuances about the rb26, GTT box or even better tricky bits encountered during upgrade, but seems will learn it all on the job.

Str00th did the same to a 200zr that was up for sale around mid 2011 but no real details or info on where it went?

PMd str00th ages ago and his insight was 'don't do it'. We all know what the natural instinct is when we hear that response...

depends on the z31

is it vg or a rb

if rb its a bolt in job

if vg you need to rear mount the sumop ( little bit more work)

gtt box slapps straight in minor cut and shut of the cross member. pull push doesnt mateer just determins what clutchand slaev you use

wiring is easier in the z31 as it old school

ic is a bit of a pain but once again really not that hard

and you need to run a header tank on teh radiator otherwise its a bitch to bleed

one of the easier conversions youw ill find

[pauls]

Cheers,

Has vg, but have sourced rb crossmember.

IC?

Will be going upright radiator, thus no header tank needed?

[GTSBoy]

I think you should expect the top of the radiator to still be a lot lower than the top of an RB. Hence a header tank. Way back in the way backs, the VLs used to crack heads a lot because mechanics didn't bleed them up properly, and the nose on a VL is not as low and pointy as a Z31.

Awesome, thanks for the input!
