Firstly Hi to everyone, I've just started posting on this site so go easy.
Thought I give you guys a run down on the beast and see what you think.
Over the last year or so I've been slowly working my L28E out of my 280zx.
We started with a stocky that had logged a few km's up and was lucky to be pumping out 60-70 rwkW.
The first mods were installed in a relatively short time and as expected I slapped on a Finner-Filter and built a 2 1/2" exhaust system for it. Bang we went up by about 8kW and the torque curve started to level out.
But not nearly having as much power as I wanted we ripped the top off the bastard and fitted a reground cam from EFI hardware. This was sick! Grabbed an extra 500rpm (6500) and found another 20kW.
Wasn’t long before this became boring also so off came the top again and the ports were opened up the valves, valve guides & valve springs were replaced and base shaved straight. Not bad a bit more power but far more torque and smoothness in the operation.
But alas it wasn’t long before the bottom end dropped and it was time for some work down there. So a new set of pistons, rings and a mandrel hone was thrown together with some new bottom end bearings and a deck shave. Whooo hoo! Up we came to around 110 rwkW. And that’s with completely stock intake, injectors and computer.
So I changed them! First we had to make and fit some aluminum injector spacers cause the bakerlite ones just fall apart. Then we fitted some re-worked injectors designed for about 15% more flow. A modified fuel pressure regulator was then fitted and finally a Hawk engine management was installed and the dizzy was welded up to remove acceleration advance. Zippa de do da we had 142 rwkW.
I like! But still not quite enough.
So I quickly borrowed a mates nitrous kit and gave that a squirt. With a bit of doggy installation we managed to use ¾ of a spare bottle setting it up and 1 bottle playing with it.
The final figures 206 rwkW!!!!!!
So whats left. Well I’m still running the stock inlet and exhaust manifolds due to some VIC roads problems and the nitro has since left.
So the work bench at home currently has a new manifold being built on it with a 1.5Litre plenum for some serious power and some new extractors are being built. Couple this with replacing the stock pissy throttle body and I should hopefully see that 200 kW figure without the nitro.
Then its time for the nitro to return.
So how many people out there think I’m nuts and how many think I’ve missed something?
HELP!
