Tell me what you think of my new turbo manifold. Its on my series 5 powered 1st gen. A friend of mine made it for me. The flanges are 1/2 SS and the piping is 1/8 thick 316L SS. Its fully divided and the new turbo is a 60-1 hifi compressor and a 1.00 divided Ptrim exhaust. The wastegate is a tial 40. Its all done now and im very happy with it. There is very little lag compared to my hybrid turbo and its much smoother than the old setup. Ive had it on the dyno and it put down 290 at the wheels at 10 pounds (stock port Jspec motor). I could not get the boost to go any higher because the boost controler was not working right with the new wastegate. More dyno passes at higher boost will be coming soon.

A pic from the bottom.

 

Awesome! How much?

 

Ya I got a 85GSL with a S4 turbo 2 motor. How much for that manifold?

 

RX-7-8593,
I see you have a heatshield around the turbo. That shield looks bad-***. Can you post some pics of that heatshield, especially where it mounts. I am looking to make something similar.

I asked him how much to make another one just like mine and he said he was unsure of how much probally around $500. He makes turbo manifolds and kits all day long (mostly hondas) and he is now looking into making more them for rotaries. Right now he is working on a ported twin turbo 12a in a 73 celica.

The heat shield is mounted to the exhaust housing bolts it does an excellent job of keeping the heat off the hood. Here is an older pic of it before it was cleaned up. Ill post some finished pics of it soon.

Where is the piping for the wastegate?

 

Why did you place the turbo so far forward? Looks like you don't have any room left for the air filter. I really like that heat shield, good job.

The last pic was taken before the waste gate pipes were welded on. If you look at the previous pics of the manifold you can see the way the waste gate is mounted. All of those pics are 3 weeks old when the manifold was being made. Ill post some new pics when I can borrow a digital camera again.

The manifold was placed really far forward to get the 12-13in runner length I wanted while keeping the pipes as straight as possible. Kinda looks like the AUS ones made to clear the steering box. The filter does not attach directly to the turbo there is an elbow that comes off and points down and away from the radiator and the filter attaches to that.

 

ahh, I see.
Is that tubing or pipe you used for the runners?

 

Very nice

& good results, you would have nice responce with the divided set up.

I love TIG's never again will I make one with a MIG !

Its 2in 316L pipe.

Yea I was amazed at how the response was on this turbo comparied to the S5 hybrid turbo I had before which did not lag at all. This setup does not lag any more than the hybrid but it seems like its a hell of a lot smother and wants to pull forever even past redline.

 

Nice job......I'm jelous

Can you please post a pic of the entire engine bay?

Also what engine management are you using?

Thanks

 

ahh.. so now you know how much of a PITA it is to work with SS pipe. Did your friend backpurge the pipes while TIG welding them?

I dont have any more pics of the engine bay with the new manifold on I have to get a hold of a digital camera again to take some more. Im runing a haltech e6k for engine management and I love it. I drove the car every day for 4 months on the old setup with no problems and with the way I have it tuned it gets much better gas milage than my stock 3rd gen.

I asked my friend about backpurging the pipes and he said for the wall thickness that my manifold is using it would have been unessesary.

 

Cool, I didn't get to backpurge all my pipes when I welded mine also. Mine is also 1/8" wall but I'm using 1.5" 304L. When looking in certian areas I can see that I didn't get full weld penetration but I'm guessing because of the thick wall it won't be a issue.

 

Here is one more pic of it after it was used for a few days!

 

Looking for a heatshield. I'm assuming the one you have was made ? Do you have access to any more of those or was that a one time fabbrication ?

 

any boost creep

 

is ther any way to find out if that will fit in/ona 89 tII?

 

wow outstanding work. let us know how it works out.

 

Where did you get the turbo from?

 

This is an old thread, I dont think he's around anymore.
