RB 240z Conversion

[datsun dave]

So Warby's got wise and his old nail will fly now ?

Its not Warby you are barking up the wrong tree

Whatever it's still sh.t colour in'it, at least it stands out!

What mounts did you use in the end Dave?.

Will be getting a set from Rick Wong $250 + shipping as you pointed me in his direction

Did you use the Toyota mounts ?

Also been to see Andy today as he lives 8 miles from me and have had a good chat with him about the conversion, just glad that i can call you both up for those daft questions "Where the Hell Does That Fit"

 

[GTR-240Z]

Mike should be able to get the mounts from an 86 supra if my memory serves me right, I can try and find the part number if needed. Rick should sent you instructions on what you need to do anyway.
If your replacing the turbo's then fit the mounts first as the mount on the turbo side is a bitch to fit as there's no room to fit the bolts easily.

Welease Bwyan then ! Or Mr Turbo - I don't know anyone else except Glen !

 

[240z]

Great stuff - tell us all your plans!

which RB are you going for? the RB30 bottom, rb25 head is a great combe, just a shame the RB30s are plentiful like in Oz!

Are you staying standard turbos, or going wild single?

What engine management are you going for? good opportunity to go for a good standalone.


Keep it coming!

I think Thor or someone like that has a container full of RB30 bottom ends

I want a NA RB conversion, but so far haven't figured out how to make any significant power from it

I got a quote from Thor for an RB30 some 12-18 months ago and it was quiet reasonable, if you search t'internet (particularly the GTR forums) there are a number of people that have sourced them and built serious
engines.....cant drive them for sh*t (well certainly not at the Pod) but seriously nice engines never the less.

OK chaps hold your horses

RB30 with the RB26 head bigger Turbos - Bigger injectors all very nice but 5MPH and 20K NO NO NO

I want a driveable car that also performes well on the Strip & Track Days

I think that i will go the RB26 Twin Turbo version rather that the single one

1) Engines are both about the same cost to buy
2) Same time & costs to put in RB25 or RB26
3) RB26 bottom end is stronger so if i do want to play it will give me more scope
4) Both use the same gearbox

What would the advantages be in using an N/A RB26 as a base engine ?

 

[SKiddell]

That was my original plan when contacting Thor/OS Giken

Use an RB30 bottom end (but use custom pistons as the existing ones are low compression.)
Bolt on a modified RB25 head and then use the individual throttle bodies I already have, giving me an NA twin cam 3 litre and about 320Hp and no spinny things, yehawwwww

 

[datsun dave]

Skidders you Hybrid

 

[SKiddell]

I know

I thought it might have gone un-noticed but a certain big fella with a beard said "Not a chance"

I wanted to do this because it'd be in the spirit of the 240. Also it fits in with my car fleet plan

N/A tuned monster - 240z
Turbo monster - 300zx
Supercharged monster - 350z

It makes sense you see. The RB30 bottom end from what I've read had some odd harmonics or something, and wouldn't rev as well. I have been discussing an NA RB engine for a while now, I'll try and dig out the threads when I can.

Found my R33 GTS-T RWD gearbox picking it up in the morning
will post up some pictures over the weekend

Saturdays morning effort

Looks a pretty mighty box, once exposed to the usual Porter spit and polish I have no doubt it will be a work of art, shame its underneath..
