L28 Engine Build

What cam?

72works copy shouldn't have any problem with flattops.... People say you run into problems with 74 but ive run it and it was fine, dialed in spot on with a vernier gear though

[noddle]

If you don't score the turbo pump from blax240, I have a H3.3 I might be tempted to part with, as I have an H4 & a new hi flow I bought from SWR some time ago. Send me a PM coz I might have something else that would help your n/a that I'm not to fond of advertising on here.

Cheers, D

Is the hi flow you got from SWR a H4 ?,

if it's a H4 then I suppose it worth the $137 they want for them,

considering that to get one from the US would most likely cost about the same.

No it's not that I know, but Stewart Wilkins claims it's every bit as good as the H 4 pump, but it's non genuine and it's NEW!

The blax240 pump sold for about US$74.00 = about AU$80.00 plus freight, about AU$30.00, but it's a secondhand pump.

And Dan, the cam I speak of is the speedo drive, isn't it a half shaft thickness offset idea? Cam?? as opposed to the spline in L20 & 28ET???

And my new motor is coming together nicely, will post if interested later. Still waiting on a few parts to come from US of A.

Cheers, D

I was asking coupe what cam he had in his motor already,

I know for sure l4 NA motors have an offset tab arrangment for the dizzy... same as what goes into the oil pump side of a turbo motor.

My current L26 came with a mystery cam - couldn't find a receipt for it. I'm going to donate it to my friends 240k project. The L28 that I am building now has been set up with a Wade cam grind 733A - cam lift 320. There was buckets of valve clearance with the mystery cam, so I'm hoping not to run into any problems with the Wade number. Maybe I'll retest to be on the safe side.

I slept through the end of Blax240's auction and lost the oil pump, so PM's away to Ghostrider.

Another thing, the oil pump i scabbed out of the hr before it got thrown out was a h4 pump.

Just about ready to go now...

You need a tripod for your camera.. :-)

It's only a mobile phone, and my hands shake from too much coffee!

Looking flash as there Drew, makin me think I aint spent enough time cleaning and shining mine up

[coupe72001]

Etch-primed, primed, and sprayed in acrylic. The rest of the car will end up that color in a bit, too.

[coupe72001]

The block is 280zx, with the dipstick holder pressed into the side of the block. The sump is L24 skyline, and the oil pick up is too. The skyline sump also has a dipstick holder, so I will retain that one, and remove the redundant 280zx dipstick holder from the block.

I won't be able to work on the car for 5 weeks though. My mate is away, and the car is in pieces at his house. Bummer.

sorry 2 bust in here but sort of on the same topic.

put a 260z C "nismo"? cam into my l24et, but the cam doesnt have any oil squirters. now the cam lobes r dry, this gonna cause a problem? thought all L6 cams had the oil squirters. if not how did they get oil up 2 them?

also idle vac is now at 10 In/hg use to b 15. runs fine etc but yea that normal?

cheers...

You will need the external oiler that comes with the head you got the cam from if it doesn't have internal facility.

Cheers, D

and remember that 'nismo' cam was for a 2.6 carbied N/A z car... not an EFI under boost.

all i can see it doing is moving the power band up or down somewhere for a short period of time....

do a re-grind mate!

[OUTATIME]

cheers 4 the info guys. yea just put the stock 1 back in for now. will b up 4 sale soon if anyones interested?

yea thats right Andrew, did rev out more. but deff lost down low torque which i didnt like...

[Ghostrider]

I'm about to embark on this project too.

Does anyone know where I can get 36mm exhaust valves to suit the P90 head?

I have all the trick bits, so I'm expecting some real good HP numbers when this 2818cc L20ET is finished.

Cheers, D
