I do think their choice/decision to use a twinscroll/divided t3 turbine housing chokes the top end, but supposedly the boost response is very good. I haven't seen a kit firsthand. On track maybe this matters more, on the street it doesn't matter at all.

Ultimately you can't go wrong with either kit. It really just depends on what your goals are. If you're used to making 450+ on pump, it sounds like you'd be disappointed w/ the SOS kit.
That's what concerns me. They may be floating around, but I haven't seen the SOS kit on 93 octane dyno sheets. So, I'm curious as to what they are pushing on 93.

I also agree that the manifold would be the limiting factor in this kit. I just love how simple it is lol.

The Mitsubishi flange they use for the turbo and manifold, in my opinion, is what keeps the SOS kit from reaching the power others do. But like stated, they SOS kit was made with road course use in mind, not all out drag power. There was one guy that claimed over 400 on pump but never really had a proper dyno sheet to back it up. He started having some issue with something and never posted up much after. It will all come down to what you're building the car for. In my case, I wanted a car that was more well rounded, a jack of all trades but master of none sort of deal. I want to track my car but I also wanted to have 450 plus horsepower with room to grow. The growth issue is the what lead me away from the SOS kit. I had a sidewinder but underhood temps weren't to my liking. I couldn't imagine the heat under the hood during the past weekend at the Dragon if I still had a sidewinder. There are few kits that fit what I want. Honestly if the Ptuning kit lets me down, my only other option would be a Kraftwerks SC or single cam swap

that was another place that installed the SOS turbo kit and compared it to the SC kit.

I'm definitely concerned with the heat as well.

This s2000 currently is just for weekend enjoyment, spirited driving, kind of deal. If it was steady over 400whp, i would definitely be interested a lot more.

*EDIT* called them. they said it was on 93 pump. He said it was a nice clean install. The manifold is what's killing the power. He said he recommended full race lol

Interesting, hadn't seen that. Sure looks like the motor is choked past 10psi. I agree the simplicity of the SOS setup is the selling point. I'd love to see someone do a turbo setup w/ a log manifold (something like an IP) and use an internally gated turbo. It would take some fiddling to see what'd fit. Then just use the SOS v mount setup. Should make for decent power and spool, and a simple track setup.

The car in that link is Rain Haters car. He has the most experience and most detailed thread on that kit on s2ki.

Thanks. I saw that before. I just don't see many more than just the couple of those threads.

but was looking for the "people" that SOS says bought so many of and maybe more people could've chimed in.

I think a Full Race prostreet kit with a Borg Warner EFR 7163 would be bananas.
Agreed. I would love to see this with the v-band IWG setup. It seems like the turbo is small enough that it should fit.

Isn't the prostreet the one that requires the relocation of the battery and fuse box?

I don't think it's required, but suggested. Pretty much any turbo kit is going to have heat issues with the fuse box but a heat shield should take care of that.

ROFL just read through Rain H8trs whole thread.

oh man. Definitely didn't see a lot of the last stuff.

So it's either the manifold. or The turbo needs to be the GTX3582r *or was it GT3582r* turbo keep from falling off at 7k rpms.

Thank you all for your feedback! Unfortunately, there is some bad information still lingering from prior threads where a GTX3576 was chosen against our recommendation based on the customer's goals. That turbocharger created a flat power curve above 7000 RPM exactly has the compressor map says it would. For power above 150 WHP gain, we suggest the the GT3582R. We have many customers running this turbo making well over 500 WHP with this turbocharger.

A forced induction system is always about compromise including issues regarding packaging constraints.

We designed our system specifically for the customer that values a well engineered system that produces a 150-300 WHP gain that is actually usable and does not degrade the driving experience of the car. Above this power level, the kit wasn't designed for these peak numbers and there are other options in the market that may be better suited for this type of customer.

For this power capacity, this is one of the fastest, if not the fastest spooling system on the market. In addition, it is the only one that we are aware of that does not require relocation of A/C components, the battery, fuse box, remote mounting the oil filter, or adding an electric scavenge pumps. Just as important as performance - the quality of materials and build quality has stood the test of time on daily driven and track driven vehicles.

Thank you for your interest, your support is very much appreciated!
