not familiar with the brand.. keep in mind you need an external oil pump, all custom work.. not as easy as you would think. There are also turbo kits for that engine already.

Is this, like a downstream turbo?

I totally love that idea. Huge sleeper potential.

Post Re: STS Rear Turbo
its exactly like that Ryan... its a great idea if someone wants to go crazy(like me) and put a twin turbo set up for the 2.5 v6 cuz it totally eliminates the problem of engine bay space as well as provide passive cooling becuz the turbo to intake piping is cooled via the air traveling under the car... jus for clarification and because i dont get but 15 min at a time on these computers Megasquirt is what everyone is using to tune these turbo KL's right...? and jus google search STS turbo and they'll pop up... they did a twin turbo set-up on a Lexus IS-F it was Sick....it was in Street Fire

It is indeed a very good idea. If you read up on the theories and results from people who have done it...

It doesn't lag because the volume between the turbo and intake is the same or less as an I/C. Also, the air doesn't lose velocity through the I/C

The only loss I can imagine would be the length of pipe between the turbo and the E/M, but then you don't need fancy headers anymore either, thats lots of $$$ saved, plus it keeps bay temps cooler.

Another bad is you need an auxilary oil pump for the return line.

A pro is you don't need a muffler. $$$.

Another bad is air filter locations are crappy.

but overall.. a sweet idea! I tink twin turbo-ing with that would have plenty of lag though... unless you put the turbo's face to face. I'd rather just have a single, well designed turbo.

I absolutely love the idea. Motivation to work harder on my own stuff... Not that my K8 acting more tired lately isn't enough motivation. I still hope I can save it, it's a good Engine and has put in 162+ thousand miles already... I drive it very hard considering, and until very recently it never gave any sign of problems.

Post Re: STS Rear Turbo
I've heard about remote turbos and the idea does sound great.

I remember reading about this on on Passion Ford which sparked my interest.

The guy stuck a 3 litre V6 Vauxhall (General Motors) engine into a Ford Ka and then the turbo in the trunk. Not sure if the project was ever finished though :(

I hope this works out as well as it appears to. I'm not looking to buy their universal per-say, but scavenge some ideas. I do like the idea of cutting down on costs, and enabling myself to go the turbo route safely, without added risk to my car.

I'm not sure how much this would save you, or reduce risk to your car over a typical turbo setup

Post Re: STS Rear Turbo
These systems have been on the market for 10+ years. They're not extremely popular because people have a hard time moving away from the conventional way of thinking. The major advantage of a setup like this is it's simplicity. You don't need special manifolds, most users don't run an intercooler which limits the amount of boost you can use safely but keeps the simplicity factor high.

Obviously this isn't going to be comparable to a front mounted T3/4 with a big intercooler, blah, blah, blah...but it won't cost as much either and is much easier to install. There's no elevated heat in the engine bay. Because of the length of the piping from the turbo to the intake 5psi would probably not require an intercooler. There are lots of upsides.

Moneywise it would save a great deal, if the above posts are correct. As for reduced risk to the car, I should clarify. I meant moreso in regards to lower bay temps, more bay room(important to me), and fewer components to break. :P

I'd heard about them previously, but never put much thought into it(lord only knows why), and I have nothing against being unconventional... hell, I prefer it! Most of my friends went VTEC, I went K Series. If easy and conventional mattered to me, I'd have a turbo'd CRX right now. I love the extra room in the bay, and I am wondering if this system would work for 15 PSI(maximum, not DD boost) with a small intercooler? Wondering if you'd happen to know that, off the top of your head.

Thanks!

according to their website yes. They have a bunch of optional add ons for higer boost applications.

I would love it if someone would try this on an MX-3.

Ah alright. That's comforting... I should have delved slightly deeper into their site. I mainly read the testimonials, which I found a little too upbeat. There was ZERO neutral/negative feedback. I wouldn't expect negative, as it's a testimonial(bad reviews = bad sales), however neutral points would be expected.

I'll likely go this route, pending more research. I LOVE the thought of keeping my engine bay clear. Sadly, you'll have to wait a while to see anything TB related coming from me. Funds permitting, I would do it now... Sadly, they aren't.

How I see it, you have more components to break. You'd need the same components and the addition of an external oil pump. All these are under the car exposed to the conditions of the road.

This would remove the need for headers + intercooler(assuming low boost) and would save a bit, although I'll give you the oil pump on that one. Didn't consider that when I wrote that.
