What can everyone tell me about the S20??

G'day George,

Nice rare Skyline you got there :kewl:

The S20! well...A two litre six developed from the Prince Motor Companys GR8 Engine used in the R380 series of race car from 1965. The 160PS S20 is an over square motor with an 82mm bore, 62.5mm stroke, hemispherical combustion chamber, 9.5:1 compression ratio.

. After the August 1966 merger with Prince, Nissan Introduced the S20 in the first Skyline GT-R in February 1969. A 4 door known as the PGC10. The S20 was also used in the Fairlady Z 432 (PS30) Same body shape as the 240Z. The S20 also appeared in the next model Skyline GT-R , the 1971 KPGC10 two door. The last appearance was in the 1973 Skyline GT-R (KPGC110). Same body shape as our 240K two door.

4 valves per cylinder, 3 44pph Mikunis and 2 overhead cams (there's ya 432!) This combination created an engine that would happily rev to 9K+ and produced the most spine tingling note at full song!

Sadly It had a relatively short sales lifespan. Many survive today in Japan, but expect to pay at least $60,000 for an S20 equipped car in need of a lot care. Top cars will trade hands at well over $100,000. The few motors that appear for sale start around $25,000!.. One motor that did escape Japan is now part of an amazing Z 432 project in the U.K. This particular motor turned up in a Melbourne wreckers yard in a very sorry state in the mid '80's. It had been imported as part of a job lot of parts including a couple of G nose fronts for the ZG Fairlady. A wily Brit gent (who on occasion has frequented this very forum! :innocent: ) heard of its escape, and snapped it up. I recall the advert in "Auto Action" and a price of $8000 comes to mind!!!.

There is no doubt a lot more to tell of the S20 . I hope this gets you started.

Jim.

Well now that Jim has said it all :P I have nothing to say, but! I can provide a pictuer of the R380, at least.  

btw, the wily Brit gent owns a spare S20, does he not?

I believe he does, but which is which, and where he aquired a second from is his story, and would be no less interesting than his others I'll bet :)

Jim.

      I'm not 100% how the BMW racers do it, but I know from other brands like Merc, moving, and changing the coolers is one of the things. Like getting a transcooler out from infront of the radiator to out near a wheel arch. So some of the stuff you've got crammed in the middle front, spread it out and open up where you can in the bar to get more air in to the sides.

      Small update for the day... Turns out the intercooler and engine coolant hose kits are anything but complete....I probably should have counted better but it only really covers about half the coolant hoses in the car, it really just covers the visible stuff and pretends everything else doesn't exist (turbo water feed and returns and also heat exchanger lines through the 2 pumps and cooler) .In any case, I'm happier to have half reliable hoses than none, but a bit of a disappointment. Anyway...finger click (and 5 hours).....hoses in place, lots of spring clamps replaced with screw clamps, and engine coolant is on the pressure tester for the night.   Incidentally, upsized header tank is an Inifiniti factory option....not sure I'll ever do prod car racing in this but at least it is legal.

      Just weld it onto the hot pipe. If you want it right after the turbo, put it right after the turbo. Or rip the comp cover off and drill and tap a hole into it.

      hahaha glad I can rely on you two to go on a spiral at the drop of a problem! Some quick answers....the ducting is excellent top bottom and sides....everything that gets in goes through the coolers (noting the oil cooler redirects it out again, fair call if it is cooling 120o+) and the heat exchanger for the intercooler also has some scoops to pick up more than it's fair share too. I can't see going down the water spray track....no bueno for formal racing and a big risk for long rally days if you run out (plus I'm not clear if it is allowed there either yet).   Frankly, it must be possible to reliably put 400kw through a standard front end, the BMWs do it so I just need to work it out....I'm starting with reducing blockages in the way and adding some coolant capacity with a bigger header tank, flushing rad and making sure it was filled/bled properly (I didn't do the last coolant change); also taken measurements incase next step is a bigger/higher capacity custom radiator

      R32 GTR Limp Mode?

      wow, a completely stock GTR! I've got to admit, I have no idea from what you are describing....do you have  any idea where the "thump" comes from, and are you certain it is the HICAS light not something else like the cat overheat light?
