L28 Turbos in Australia???

[Ben]

Steve,

I can only count 4 plug wires & fuel injectors in that R30 engine bay - It's a Z20 or Z22 (it's got the tall block).

And it had the twin-plug dizzy (only 1/2 used)

Still it looks the goods, doesn't it?

Langwarrin is in Victoria on the Gippsland side of Melbourne.

Mr C. check this site out, looks like they import just about anything that burns fuel and rubber from Japan...http://www.c-red.com.au/

Ben, yes agreed it is a z series engine but nicely bombed, very handy with the plumbing these guys. Id say by the look of it, it would wind up pretty well ( for a Z series).

Cheers

Ben's pretty much got it all nailed down there.

Ben I'd like to know more about these dealer turbo options????

I have a L28 P90 Head F54 BLock engine here not sure what compression it's running haven't pulled it apart yet. Yes Simon's L28 is a mean piece of machine. I have another friend www.geocities.com/spized1969/ who has an L28 turbo in his car I think he's using a N42 engine head. THe car makes 200RWKW he's hoping to upgrade that soon with a new turbo and aim for around 230rwkw +.

Basically the intake manifold is different. The exhaust manifold will have to be fabricated. To suit a turbo. The ZX came with a T3 stock much like the VL but without water cooling I think.

You will need an ECU not cheap should buy a good one.

Gearbox might be a problem u could use a late model FJ20 unit I believe not sure on the mods required. Z boxes are pretty strong anyway.

That's all I can think of for now I've missed bits and pieces I'm sure.

Apparently my local dealer was fitting aftermarket kits to R30 Skylines, 280ZX's & S12 Gazelles (Silivas). They used a J-pipe, (one of which, I am using on my L28T) an aftermarket ignition retard module & modifications to the EFI to supply some more fuel to the system. Boost was apparently ~5psi. Pretty primative, but it certainly gave the cars a heck of a lot more mumbo!

They eventually had to stop as the authorities were a little concerned about the number of cars that were not fully ADR'd coming from the dealer...

If you have an atmo. P90 & F54 combo, then it would most likely have flat-top pistons in it. Theoretically this gives you a CR of 8.52:1. If you simply fit 'N42' pistons (dished) that will lower your CR to 7.38:1. How much boost did you want to run again?

:classic:

However, I'd be careful using stock pistons as they may not like the amount of cylinder pressure that a CR of 7.38:1 would allow you to apply.

I'm using a stock NA inlet manifold on my current engine, but my stroker twin-turbo has a ported import manifold with a larger plenum on it.

I'm using a VG30ET T3 turbo (same as VL) with a T4 compressor & enlarged turbine outlet, and that's great for 200-300HP. I'd go for a BB unit from an RB25DET if I was building a new motor. That should be big enough for starters.

An ECU will set you back ~$2k for a complete setup. But it's worth every cent. The stock gearbox will cope fine - just don't abuse it. If you need more strength, then an RB 'C' series can be adapted to fit, or you can get a Hollinger gearset for the original box...

Personally I've found that the FJ boxes (although they are theoretically 90% the same as the L boxes) tend to be a little more 'crunchy' on fast changes. You just have to learn to shift with a little care!

With 200kW of power, I'm sure a gentle gearchange won't be too hard to cope with....
