What was wrong with the old cast manifold? Just wondering. It's good to see some positive results from the new design and your effort.

 

The old cast manifold took too long to machine. In order to leave the pricing where it was, a new version was needed. Welding on CNC parts is a lot faster and cheaper. Plus that was for higher boost applications only. We needed a part for 12 psi applications or less. We are happy with the results on the bent tube version, and can't wait to test it on more applications.

Need a tester for the 94-97 1.8?!? Huh, huh, do ya!!!

Just finishing a mild build. No crank work - likely stupidly since everything was apart - Wiseco's, m-tuned rods, some mild head work - mainly deshrouding, 3 angle job, port matching, casting clean up - and your S4 system. Motor is ready to go in, just looking for a block of time to make the swap. I could do before and after dynos. Looking to make that ubiquitous 300hp reliably.

 

So whats the dilly? I saw on your homepage that one of the runners was back from the foundry and it looked awesome.

 

The runner arrived with a small hole in the casting. Corky is fixing the core box now, and it should be off to the foundry in a few days.

cool thanks for the update. So its looking like next month maybe till they are ready for sale?

 

The pattern has been sent to the foundry again. I am told a sample should be here in about 2 weeks!

Months later, any updates?

 

Three foundry samples later, we finally have a casting that poured correctly. They are making more castings for me, so we can do some more testing and start selling them! Pictures to be posted in a few.

That looks fantastic! Ive said it in the past but i really wanna be a guinea pig! I have access to 2 dynos i can use whenever to show before and after results.

 

I'd gladly be a guinea pig too, just throw one in the box when you send my turbine housing back, lol

 

I know this is MiataTurbo.net, but any thing that will work on a high compression NA 1.6?

 

Looks like a pipe sherlock holmes would puff on.

 

Yes. A turbo.

 

Those runners came out nice. I'd like to see the project completed!

How long are those BTW, 9-10"? They appear to be shorter than stock, I like the smooth taper. with the right plenum I can see how you'd see improvements throughout the entire powerband.

 

Yes, very nice indeed. Get on it begi.

 

Taking FOREVER!!!!

 

I KNOW!! We are waiting on the foundry to ship us castings at this point. The foundry had our approval for 15 more castings the same day the last sample was sent to us. They have more in the schedule to ship later as well. Just waiting on them. I have a car here already, waiting, for back to back dyno testing.

Any updates?
