Rear mount turbo...possible?

whatwasthat · 11-17-2009, 11:20 PM

Has anyone ever visited the STS turbo site? They make rear mount turbo kits for some cars. Would this ever be possible for the spyder? What I mean is, is it possible to install a turbo on the end of the exhaust system for the spyder?

I hope you all do not think I am stupid for asking. Just curious.

I haven't visited the STS site, but I can tell you people have swapped in the 2ZZ, several Toyota V-6 incarnations, supercharged and turbocharged the Spyder. A turbo kit can be found here (disclaimer, I do not work for them, and have no experience if this is a good product or not): MWR Turbo Kit - GT28XX - Toyota MR2 Spyder 2000-05 - MWR-5051X5 van Monkeywrench Racing -

I went to their (STS) site - turbos added on as they do apply primarily to front engine vehicles already tight on space. There is an increased amount of turbo lag encountered just to save the cost of an exhaust manifold. Not a good proposition IMO.

Actually / Amazingly, the lag is not that bad at all. I had the chance about 6 months ago to go for a ride in a Pontiac GTO that had a STS setup on it. Boost came on very quickly to my surpise...

Installing one on a Spyder would theoretically lessen any lag from the system do to the engine being in the back already thus having less travel distance from the engine to the turbine and the same for the compressor side of things. One thing to remember here is these are systems that are designed for low boost applications. If you were to lower the CR (compression ratio) in effert to run much higher boost, then yes I think lag would become a big issue..
