RB 240z Conversion

Well what a Year it has been i think i have been up to Santa Pod more times this year that i have had hot dinners !!!!

The Club has some great car running in the Drag Race Challenge 2006 and well done to Peter Mac on winning it.

Steve Kiddell stands out from the crowd for me on his persuit of that dream L6 NA time, steve if you have not meet him is a true gent and has all the time in the world for you.

So taken all that i have learned this year (and the last 20 years of Z ownership) i am now going down the RB skyline conversion route.
I have spoken to both Darren Styles and Andy Shaw how are both well into there RB swops both chaps were very helpfull with items required and bits that i need both here in the UK and over in the US.

Mike at MJP (another gent) was my first call for the hard to get 200ZR sump to swop over on the skyline engine (the skyline sump is the wrong way round and hits the front crossmember on a Z) so with the sump & oil pick up on order from MJP - engine mounts on there way from the US. The Skyline Gearbox is hopefully sorted its just down to the full Engine & wiring loom & ECU to be found.

A lucky Club member has bought my existing Engine-Gearbox-Carbs-Manifold-and Stainless system as a Job lot, lets say that he will "Have a smile like a Cheshire Cat"

Also will have to look at a Buying/sorting:
Diff for the rear end/Drive Shafts (that dont break at Pod start line)
Prop Shaft to be made up
Intercooler/Piping work
With me having a early 240z i will also have to make up the gearbox mounts as the kit you can buy is for a 1971 onwards

I loved the TVR build up on this web site so will be trying to do the same with write ups and photos added when i get started.

Whoaa talk about breaking news, I think the RB route in the quality/look of your car will be brilliant, plus your not afraid to use it, so it will see regular outings to the Pod.....currently we have absolutely no data on what an RB engined Z will do, but my guess is that a mid 12's could be on the cards depending on how mad you want to go......hey maybe even ....no don't even think about it.:devil:

Come on Dave get your skates on

Gentlemen start your projects on who can be the first RB engined Z in the UK, winner has to have a road legal fully mapped car either on Video or appearing at a Z club event.

Nice one Dave, I too am changing direction with my engine after it let go at Donnington, as I am going the L6 Turbo conversion, this when tuned should also be capable of going at least mid 12's. so my 240z will be in the garge for at least a year...plus ..but when it returns it will be a beasty....

Sorry Dave, I meant to say we have no data in the UK.................... anyway American 1/4 miles are differant (shorter:D) Plus wasnt it the case that in the US, the Skyline was only ever an indirect import and never sold directly from Nissan, so RB25's and 26's were more prolific in Japan (naturally), Aus and here. Possibly wrong there but felt sure I read it somewhere

Look into my eyes, my eyes, not around the eyes but into the eyes
When I click my fingers you will go to OS Giken and get them to build you an RB 30

Seriously though guys (Dave I know you are know this;) ) for anyone interested the RB30 in stock form is not earth shattering (its a single cam jobbie) however OS Giken make a kit

which bolts an extension on top of the RB26 engine block, and fits liners, to give a 86mm bore x 86mm stroke. It is available as an assembled short block, containing billet chro-mo crank, billet chro-mo H-beam rods, forged pistons, and costs ¥1 500,000.
basically fitting an RB25 head onto this combo will produce some stunning results ----- should do really for that money:(

Tongue in cheek - is this because you'll never catch Mr Skiddell ;) ?

Also, re the sump, if you moved the engine back (and improve the weight-distribution) would the original sump still hit the crossmember ?

Great idea and I look forward to reading about it, seeing the picture and with your permission, copy and translate it for the French sector !

It's Sean that calls it that colour,I was being kind to it because he is right for once it IS s..t brown. Is it Warby who has bought all the gubbins off it?

No, no, no - it's Alan that calls it baby sh*t brown - I call it peanut butter sh*t brown :)

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