Very interesting intake manifold too!
Looks similar to a chopped up RB intake??

have just started to make a custom intake manifold for the L28t, and i will try to make it so the heat from the exhaust does not kill hp ,i hope to have about 12in long runners and a plenum of about 6L with a throttle of 70mm
will post lots of pics of the manifold as i build

Fantastic looking engine good work Pete.

A few questions?

- What kind of harmonic balancer is that?
- At what RPM do you think this set up will make full boost?
- What type of ECU will control it?
- Finally what kind of gearbox will go behind it?

Hi Gav

the balancer is a BHJ from the USA Rebello sell them, nice part

boost will be about 20psi and it should see it all by 4000 and peek power will be 7000
ECU is a Autronic the ECU will be tuned in WA by Aaron

and Aaron has converted a VG30 box to go behind it, so he wont have any problems

this thing will look grate when its finished the exhaust manifold will be hpc and the inlet may be as well and all hoses are brade

The BHJ damper can be purchased direct from BHJ Dynamics. Similar pricing to the ATI one.

Autronic SMC is the ECU, 500R CDI w/ M&W coils(Currently running on the L24et in the car)

Gearbag is a RB25t box -> 300zx bell-housing -> Austin Hoke adapter, trying to figure out clutch now, calling Jim Berry on monday I think.

So excited to get this back and in the car :D Then I can start breaking stuff and suffer the wrath of the other half

The BHJ balances are a nice bit of kit. When the one I ran was fitted it made a huge difference to how the engine revved, I was changing gears 50k or so metres earlier at Lakeside with no other changes than than throwing the standard balancer in the bin.

not really, we had some trouble with sourcing a suitable intake, now waiting for a Lonewolf intake to be made, once peter has it he's gonna finish the small things, then send it back to me. Unfortunately i'll be moving soon so it wont be going in straight away. Will be nice to have it back just to stare at, waste some moments contemplating how awesome it will be :)

Any chance u would like to tell us what clearances ur using on the bottom end?
Also im thinking of doing the same setup but with a set of 2860-7 garrets I've got laying around. the head I've got is an e88. Is this still useable or should i just look for a p90?
Thanks.
ps the exhaust manifold looks like a work of art.
And is there any reason u didn't go multi tb ?

well there are diffrent types of E88s 240 type and late l24e .... both have small chambers the Late one has a really nice chamber for NA but is way to small for a turbo set up and the and 240z one is no good for the job ...
p90 is the best for the job by far, 53cc makes it perfect for turbo and its design lets you run more timing  than any other Nissan head

as for the itb yer they work , but make it lots harder to tune and cost lots more , is there a hp benefit no, is there better throttle responce yes  ,,,, is it worth the hassle no

My current engine is a L24 with a E88, but what e88 i couldn't tell you. I don't really know much at all about the current set-up, but it works? I've never pushed it, currently makes 148rwhpat 13psi spike levelling out at 11 psi. It's running all the gear off a L20 turbo engine, so would be quite restrictive on the intake side, which would explain the higher boost required for not too much power? On the Autronic compression is listed as 8:1, the engine was rebuilt and owner said it was given oversize pistons, possibly put in a dished piston maybe? Owner made it sound like he used the original head as he mention it being drilled to suit the injectors. Matching numbers block so that would make it a 1973 e88? All speculation on my part, I did not know as much about engines or Datsun's when I purchased the car, but I don't regret my purchase :)
