Now THAT is a callout

 

The very 1st turbo manifold offered for the S2000 in 2001 was a weld pipe bend log manifold from a very defunct company Speedcraft. It featured a low mount, on center 60-1 turbonetics turbo. Around the same time there were a few manifolds from DRAG that looked the same,

Greddy was not the 1st.

Welcome to 2001:

A Very unfortunate DRAG:



I'm pleased to see companies still making products for a limited production car that won't be replaced by Honda.

 

FWIW, I never claimed that Greddy was first, I merely named another reputable mfr that had a turbo kit before P-tuning. I also would hardly say that the Greddy kit is the "worst." Minus their manifold that cracks, I'd have to say it's a decent kit. How many other kits out there actually come with everything you need and actually fit w/o requiring some welding for the downpipe or hacking something up.. not many. Ha, man.. I forgot about DRAG, talk about old school. I remember quite a few of their cracked manifolds.

Personally, I think it's laughable to say SOS copied Ptuning. It's like saying apple pie and cherry pie are the same thing. They're both pies, right? To say "ptuning used a water cooled turbo" is comical, as water cooled turbos have been around forever (I had one on my integra a decade ago).

I applaud Ptuning's classy response. There's plenty of room for multiple kits, and people have their reasons to choose one over the other.

 

There is one thing that I forgot to mention in the last post. We have been using CNC machined T304 Stainless Steel Turbo Head flanges since day one. We actually use SS flanges on all of our turbo systems including our original Scion tC turbo system. They are uber expensive to manufacturer in comparison to a laser cut or CNC milled mild steel flange, but the rust-free look and durability of a SS head flange is worth the added expense. Our head flanges have a unique CNC machined face on the cylinder mating surface that helps to promote exhaust port gasket sealing. This combined with the final decking process that we perform on every manifold guarantees a leak-free seal to the cylinder head.

All of our manifolds are made from SS schedule 10 pipe rather than schedule 40. Schedule 10 pipe is much lighter, has a larger inner diameter, and is all that is needed to build a reliable manifold, especially given the balanced location of our turbo. All of our manifolds are also TIG welded using Argon gas back purging. In addition to that, we also make a second double pass weld on all welded joints. This is why you don't see undercut looking weld joints on any of our manifolds. These extra steps help to ensure years of trouble-free use.

Sorry for writing a short novel, but the differences are sometimes in the fine details.

I think Toan said what I was trying to in a much clearer way.

For the record, not trying to say PTuning was the first to use water cooled turbos. I just pointed that out as a difference between the greddy kit and PTuning's kit.

 

Maybe you can confirm Toan, any cracked manifolds?

 

25,000 miles on mine no issues

 

I've gotta say, if you're ever fought with trying to keep a turbo mounted, you'll realize the benefit of the Tial turbine housing PTuning uses. I've had turbos fall off, bolts go missing, and bolts shear from stress. I think I've finally fixed the problems, but only thousands of miles of driving will tell for sure. With a v-band, it's super easy to install and remove and you know for sure that nothing's going to fall off. It's also nice that the Tial housings are MUCH lighter than the factory Garrett housings.

Out of all of our manifolds from every platform we work with, which number in the hundreds, we have only heard of one reported instance of a WG flange issue. This was likely due to the clocking on the dump tube too.

We're looking forward to seeing another 25K.
