That is if I don't hack the roof one of these old Z's sitting around here.....:devious:

I'm currently looking at buying this sweet fairlady roadster that i have my eye on, and am going to swap a black SR20det into it, boost to aroud 15psi, with cooler and exhaust, and all i will be getting is wheel spin... so hopefully i'll have that finished by the end of the year, but with school and work its going to be hard... will post pics of the fairlady when i go to look at the car tommorrow, already looked at the car, no rust, perfect interoir, crap engine, perfect swap donor

Internals, Yes. But We got no, 0, rear Wheel Drive SR20's And none of the Turbo's. just FWD SR20DE's. Still an Awesome engine. It's the most desired swap for a roadster. The few that have been done look very natural under a roadster bonnet. Iv'e only seen 1 DET swap and it wasn't very clean.

sr20det's have a huge amount of parts in the U.S. now. Since everyone is using them in 240sx's, they have an aftermarket abundunce, and when somehting breaks internally, there is one simple fix that you can do and buy in america......UPGRADE IT with an aftermarket part.

i will have a sr20 powered s13 240sx before the end of this year...i cant wait to see how it does, because my 240z is lighter, and of course i would put more money into the z's motor, that might decide whether i go rb or sr

My dream has always been to replicate the almost legendary "Roadster S". A prototype racer Nissan campained briefly in Japan only. It was outfitted with the prototype of the engine that would end up in the fairlady 432 (crossflow, hemi, DOHC, 2L six). But this roadster was 4 inches wider and several inches longer than your normal SR/SP roadster

Hi Victor,

I didn't know you had an interest in that car.

In Japan, it was always called the "Fairlady S". I don't know who said that the engine was a 'prototype' of the S20 engine seen - apart from in the GT-R - in the 432?

The engine of the Fairlady S was coded "UY" and it was badged as a Nissan. It was indeed a 2 Litre DOHC six with hemi chambers, but it was a 12-plug design. It was a Nissan in-house development.

The S20 engine on the other hand had Prince blood in its veins. It essentially evolved from the Prince GR-8 engine used in the R380 Sports racers, but was re-designed for its first use in the PGC10 Skyline GT-R. The GR-8 had quite a different distributor drive setup from the S20. On the GR-8, drive for its twin distributors came off of the front end of each camshaft. For the S20, a single distributor was used at a right-angle to the cams. This took its drive from a sprocket rolling off the cam chain. There were other differences in the water and oil pump drive layouts too.

When Prince merged with Nissan, it was the Prince design rather than the Nissan "UY" that was chosen to provide the basis for the new Nissan-badged powerplant. This went into the top of the range Skyline - the new GT-R.

The "UY" was rather troublesome, and lacked development. When it appeared in the Fairlady S the merger with Prince was already on the cards, and it could be seen that Nissan would be inheriting an already-formed and fairly successful race department from Prince. Its clear that this is one of the reasons why the "UY" was not developed further.

The Fairlady S was a VERY trick Fairlady indeed. Got any pics Victor?

Alan T.

No, there is one on the web 1966 Japanese Grand Prix (do you know Rob Beddington?). My info is Very sketchy, as you can see. For instance, I had beleived that the UY WAS a Prince/Nissan design.

Les of CDM told me that the surviving UY is in a private collection in Japan. But, there is no surviving body/frame.

Thank you Alan, and any further info you have or find is VERY welcome!

Rob's a good friend of mine. His site is fantastic, isn't it? That's pretty-much all self-built and self-written. Amazing.

He's slowed down a bit with it over the last year or so. Pressure of work and other commitments ( read; LIFE ).

I'll scan some pics up for you and post them. Nissan were VERY secretive about the engine and tried to stop anybody getting a good shot of it at the '66 Japan GP.

I've seen pics of what's left of the engine, and its very interesting. I hope it will end up in a proper museum one day.

All the best,

Alan T.
