Ok guys/girls, Heres something me and a mate knocked up this week its not the best but for our first time im very happy with it, What do you think?

so close yet so far...


Trial fitting...


Painted...

I would have though that the 32/36 weber would be a difficult choice for a turbo application considering it has a primary and secondary throttle meaning that the turbo would be pushing air into a closed throttle at some point.

But the manifold looks tops!

Did you just cut up a set of extractors and re-weld? or did you fabricate the entire thing yourself?

Is that the result of Tuesday nights?
Where did the head flange come from?

Looks pretty good to me! well done.

Tbam, might have a good point there about the weber, but nissan used them in a factory turbo setup so hopefully they are ok.

yeah cut of the extractors right up the top.


Baz, this is why we are doing tuesday nights, and yeah the flange is from the extractors but the next one will be from work (laser cutter remember) just a weird size they are like 12.5mm thick???

Zac, cheers.

tbam, yes and no... there will be occasions where air is pushing against a closed secondary but it won't affect the operation of the engine at all. Speaking from experience here, of course

Ok pop in & check out the right way to make a flange
I have one left from the FIA pipe days

will do Baz will do!

the next one was going to be the same as the gasket (one piece) with a plenum made up for injection on the inlet side, but your way is probably alot easier.

A couple more pictures for those interested...







Yes i know Lovely purple motor, it was my ex's car and she got to pick the colour of the motor.... Why did i suggest that .

what's wrong with that?
it looks like a nice bit of gear!

people (magazines... ) always harp on about "tuned lengths" and equal length runners, but for a street engine they're really not worth the extra headache to achieve them.

i like it. top job















now fit some EFI already...

Dude, how much to knock one up for me ??????

cheers dude, im pretty happy with it for our first attempt.(plenty more to come)

The next one WILL be EFI and a slightly better exhaust manifold (its already in the works don't worry)

Heres a few more pics guys, It almost finished just got the fuel system and exhaust to do.

Looking good jordz! Ahhh.. don't we love the miles, and miles, and miles of turbo L inlet tract.

Couple of questions/comments

1. Isn't that the cutest little BOV you've ever seen? hehehe
2. Blue engine looks tidy
3. Intercooler is major overkill but cheap cheap so all good
4. How close does the #4 runner on the exhaust manifold come to the intake manifold? It looks quite close.
5. Where are you water lines? Not in yet?
6. Have you sprung the top plate on your plenum yet?
7. Where did you get that snazzy black paint? I like it.
