The project in well and truly underway :smash:

 

Today I finished fabricating the template for the drivers side exhaust manifold, taken about 3-4 hrs but I am happy with the fit and the shape - I think! Pictures are posted and before anyone moans about the welding they are rough tacks and I am not a trained welder :tongue:

 

I think the path around the back of the engine will just squeeze in I hope as it flows nicely to the passenger side. I am about to start on the drivers side which will be tricky as it has to run along side the feed from the passenger side before the meet where the aircon pump sits.

 

The turbo arrived today to, it's big and going to be a squeeze to fit in :smash:

 

I will keep adding to the thread and my ride as it progresses.

Brave Man. :bow:

Go on son nice work so far,, i didnt realise you were doing yourself?

:cool: :bow: Interesting project. Paul@SWZ single turbo'd his vert last year as an experiment, but has since just put a complete TT setup in there, but think he is planning on redoing it.

 

Did you measure the room behind firewall and engine to see if that will fit, doesn't look like it would from the pics ?

:cool: :bow: Interesting project.

The two water pipes for the heater/turbo feeds are going to have 25mm cut out so they and the exhaust can move closer in to give more clearence.

Good luck mate- but why do it?

I can get good power from the one and if the turbo breaks I don't have to take the engine out to change it:tongue:, it's been done on all the other jap cars so why not a Z? besides I like a challenge and to do something a little off the wall and different.

Nice work fella, I'm looking forward to seeing the results when its done.

If this works i would be seriously interested in buying a kit or the manifolds to be copied or whatever, keep me posted and good effort !!!!

A good single can boost sooner and more than twins too. I have seen pics of one where they ran the pipes round the front to the turbo down by the near side front of the engine.

Looking good matey!! When the trial fit gonna be... will be interesting to see if it squeezes in, if you need a hand just let me know :)

I wish you 100% all the best, i would love to see this work.

 

You cannot beat the sound of a massive single turbo.

 

All the best :cool:

I have trimmed the water pipes down about 25-30mm and it's made a big difference, I will post some pics in the next few days. I am hoping to finish the the other exhaust manifold this week but may change the other one slightly as one port doesn't look angled enough for good flow? Again pics to follow.

 

Then they are off to Janspeed to be copied although I might site the turbo first as I'm not sure how long they will take.

this sounds like an interesting project

I'm seriously worried that its going to fit in the engine bay with that pipe around the back. However, EVERY credit for having a go! You could quite easily reduce the pipe diameter (probably by about half what it is now) without any decrease in flow, in fact it may even prove far more efficient! Whatever happens, make sure you heat wrap that pipe as its essential to keep the heat in the exhaust gases in order for them to provide the energy to spin the turbo ;)

I know what you mean, it is rather hard to measure the clearence on the car. So if anyone has a car with the plenum off can they drop me line as perhaps they could do some measuring . . . . .

Just thought this might be of use to you ??

After some research into exhaust manifolds the the result is collective is better than log manifolds - which means mine have gone in the bin and I'm starting again!!

 

Still it was good practice and as such finished both manifold in about a 1 + 1/2 days and I'm much happier with them. I have also binned the route behind the engine and I am going frontwards where the turbo inlet and outlet hoses were on the drivers side. I should be about to get the turbo mounted in a rough position within the next few days. In the picture of the front of the engine you can see the ends of both manifolds, I tink there is enough clearence when the engine is in. The TB hoses and rad hoses will be re-routed.

 

Pictures below, what do you guys think???

i wish you all the best doing this yourself, i would'nt have the cahonas to do that

good effort mate, good luck

hks built a car running with a single turbo in japan.the turbo sat where the altenator was which was relocated.i came across it on ooparts.

wasnt HKS, for some reason HKS never really bothered with the 300zx, from memory it was escort racing which built it, i will dig it out as i have some info on it on an old back up :)

Doh !! Oh well thank god someones got a good memory :D.

Well after another day of head scratching, cutting and welding I think the turbo install is done!!:dance:

 

I am happy with the route and think the clearence will be ok. The next job will be moving the rad forward and working out the front mount intercooler. I'll get the bumper off for that but it's also a chance to try the new on.

 

As usual any feedback welcome or if you spot something I have overlooked which might be a problem.

Fookin ell :eek: Looks like its gonna be mega :D

im not an expert so feel free to dismiss my observations but I think the lower pipe is too close to teh pulley, your gona melt the belts, maybe not, but a possibility. And the PS Pumps gone get warm. but just my observations from what I see.
