1974 240k 2 door > GTR

[Guest two.06l]

we have a Datsun 240k 2 door in immac. cond. We are looking to convert it into a GTR look-alike. We are thinking an rb20de or rb25de as we would like to keep it atmo but with multi throttle bodies and some extractors to give it that great n/a sound. Question is are the parts required avail. and at what cost? Whats involved in the engine swap? Should we go turbo? Transmission options?And what are our options on the suspension/braking side of things? Any help would be much appreciated.

i just cant get the sound of the n/a r31 at tsukuba out of my head...sounded absolutely awesome. But the turbo route will give me more power for my $$. A tough decision pete, thanks for the offer of help as i will take you up on that!

Absolutley! Huge fan of multiple throttle bodies on N/A engines, they sound so cool. My cousine has a honda integra running quad throtles and it is awsome to ride in. I am considering an rb ** N/A engine conversion to my MR 30, either that or multiple throttles on my L24, as my cousine is a machineist, he built the whole induction for his integra and has offered to do mine, but will the RB 25 make reasonable N/A power? Im not after neck braking acceleration, more a reliable, smooth and reasonably quick package that sounds wicked at high revs!

cheers,

chris

2rismo gave me an idea...build an n/a rb24...rev it to 9000rpm

[gtr fan]

Well since you already have a turbo car an N/A might make a nice change, and really who cannot love that n/a sound!!!

Hi Stacey,

welcome to the C110 club!

Myself and Prank are looking at doing the exact same thing, a replica C110 GTR with RB20DET (or 3L).

Unfortunately GTR parts are very rare and super super expensive.. but keep your eyes on the japanese yahoo auctions..

differences...

external:

Front Grill (can fetch anywhere up to $800 at auction)

Skyline badges (c210 ones are similar), GT badges (R32/33 ones are similar) and GT-R badges (smaller than R32 ones)

Front mirrors (australia spec cars had them on the door)

Front and rear fenders (fibreglass flaire copies are available)

Rear light cluster (with 2x red outer lenses, rather than the australian 1xred, 1 white)

S20 engine (extremely rare!)

and and crappy black steel wheels (seriously!)

not sure if the diff and brakes etc were the same or upgraded

interior

Brushed aluminimum dashboard

GT badges on the doors

Skyline badges on dash, rather than datsun

Seats are similar to Aus spec i think

that is most of what i know of... i am sure there are ppl lurking here that can fill in the gaps

we are trying to keep a record of our build up, so you might be interested in having a look www.project240k.com, have a look especially at the gallery.

we are looking at putting an RB20DET (Nics) engine and gearbox in ours, R31 rear brake conversion for the rear, and 300ZX brakes on the front (we currently have a hybrid hilux/accord setup on the front). The Diff we are going to upgrade to an R200 from a 260Z as well, though at the moment we are going to keep unijoints rather than converting to CV's (until they break that is). Fuel system will be 1xR32 GTR pump from a surge tank, being fed by a VL fuel pump.. um.. what else...

unfortunately not much work has been done to the car of late, our other "charity rally car" has taken precedence at the moment, hopefully we will get that one to the NSW S&S this year..

also, let us know if your getting any custom work done (engine mounts etc..), we may be able to help each other out

:wassup: he he. i got the 2.4L part :Oops: just not how to build one

[floody]

Ah, why bother with an RB? Do an L28 with six throttles, big cam...Maybe even the 3.1l bottom end with the LD28 crank...

[YO880]

or go straight to an rb30dett

[Mr R32 M-Spec]

can't go past the best, RB26DETT

From what i have read/heard, to fit an rb and 5 speed into a car originally fitted with an Lseries, all you have to do is slot the drivers side of the engine xmember where the mount bolt in. 10mm i think it was.

I'm assuming the tailshaft will need to be custom, but that is the case with 99.9% of conversions anyway.

A guy on here (username Prince) has an rb20 with webers on it, he would definatley be of some help. he still runs the factory computer.

tuff Lseries with multi throttles... home built L21 in 3rd gear.

Thanks for the help guys...will keep you posted on what we come up with. Would love to keep it n/a to keep that old school theme all round.

and sorry to tell u two06l but the rb25de job is being done in melbourne atm i think

but i think a turbo would be very nice

[YO880]

greg, what do you mean? are you saying there is a C110/RB25DE build up in melbourne? details details!

[GTSR22]

the details are very hush hush and i have just found out instead of a 110 i think they are going for a 210, he has already made up the throttle bodies and all that so now just a thing of putting it together

RB25 is the way to go I reckon, N/A RB20 is a dog with fleas. And I can hear the N/A howling now, hmmmm.
