DJZ's other 280ZXs

Who cares. Just do it

[DJZ]

Can't afford it right now, and besides there's no L20s left, you bought them all!

do you have to run a OS engine? RB20DE Neo's have a good we head setup on them and they have some vacuum operated butterfly's in the inlet manifold which means a little bit of sneaky dowelling and porting and you have your throttle bodies pre made for you. An ECU and some trumpets and extractors and you could go racing. This is what i was going to do in my C110 before i decided L series was cooler.

Too many valves per cly.
Must be original and 2valve per cly

found their website. you'd be better off with a little sunny with a L20b in it or similar to be competitive but yeh getting OT.

ditch the air dam but the rest of that is win.

This was the project I was considering for ShellSport but I just don't see it being competitive with an L20 in it, and my wallet isn't that big. We'll see what happens with it in the future, I would like to get into some proper racing one day.

Have you got the full interior? Go classic racing, L series turbo, must resemble original engine, one of these on a diet with a turbo L32 would be very competitive, and look the part. Although the snobs with the oil / smoke leakers might not like racing you

Turbo 3.2L? Now we're definitely exceeding the budget maybe one day in the very very distant future.

you get that down south too do you?

You can run anything with an Alfa Badge, no matter how ugly, slow or both. Any thing with a Porsche Badge no matter if you just picked it up new from the dealer. Anything English, lets be honest they haven't built anything other than taxis since the '80s, although I wonder how I'd get on running a UK Primera?
As soon as you want to run a Jap car you don't get the invites to Skope and the like. To be fair we are fortunate, with several historic Shell Sport and SCCA Datsuns being admitted, and a small hand full or 240z's. No Toyotas unless in the Historic touring cars, which include 2004+ BMWs Only one Mazda RX3, and only because it has run since new and belongs to a long term auditor.
Jap, forget it, there's the door. Not classic, probably because the Starlet still dominates club sport. As always it's more about who you are than what you drive.
And it probably doesn't help that the Zs kick butt. SCCA and Shell Sport cars make the excorts etc. look pretty punk too
Still Skope is the best weekend at Ruapuna each year, glorious cars

Trying to start and leave unfinished as many jobs as I can, thought I'd start on the headwork for this thing - I've had a head sitting there stripped and cleaned for a couple of months. I've seen a couple of motors in the States with LD28 inlet manifolds on them and I've got the technology now to fuse the head flange from a petrol manifold to the LD28 mani (as it doesn't have injector ports) and I'll get a bigish throttle body maybe a 70mm one? Should be interesting. One good reason for running an LD manifold is the long runners but also:

L28E inlet manifold runner diameter:



LD28 inlet manifold runner diameter:



I've just started to match the ports on this head to the inlet manifold size but you can see it's much, much closer to the LD runner dia. than the L28 one!



For this head I'm going to try and make it a budget copy of the head I had ported/worked for the 3.1L motor, I'm planning on fitting it with 1mm oversize stainless valves on the exhaust side and giving it a bit of porting and a cam ground for a turbo motor, don't want to go too crazy as I don't really know what I'm doing.
