I don't know what to do with all these forced induction posts of late. It's ridiculous. If I moderate, I get threats. If I let them go, the site will quickly fill to the tits with useless "Where can I get terbocharj fOr my caR?" type posts and no one benefits.
So here's an answer or two. Perhaps a search in the future will turn up this thread and someone will get some use out of it.
AFAIK, there's only one maker of turbo kits for the MX6/Probe. It's Knight Turbos (formerly known as ATS, run by Thomas Knight) and their website is at
http://www.geocities.com/knightturbos/. I've seen rumblings on
Probetalk's Forced Induction Forum about "Turbo Tom" and "Ludespeed" but I will leave it up to the interested reader to search there themselves for these topics.
In the majority of turbo 2g-MX6 and Probes, you'll find the owner has not bought a "kit" but has rather bought components and fabricated (or had fabricated for them) their own custom set-up (Toastier and Mici come to mind, as do Ross Lapkopf, Dan Dunhem, Darren Pemberton, Allan Wong, Mike Pazsti, Andrew Brownsword, Rafi and so on...)
A "kit" might consist of, but not be limited to, the following components:
- a suitable turbo
- a Walbro 255LPH in-tank fuel pump
- a Vortech FMU
- custom pre-turbo air filter & cold-air intake
- FMIC (intercooler) if there are plans to run more than 7PSI
- custom-bent exhaust and intake piping. On the V6, clearing the cross-member under the engine may present problems
- AN fittings & braided line for the turbo oil supply & drain
- battery relocation kit
- a turbo timer is a good idea
- upgraded clutch
- blow-off valve
- untold numbers of goodies ranging from nuts & bolts to silicone couplers
I've probably left out more than I remembered.
A turbo installation on a KL (V6) or FS (4-cyl) is not an easy task. There are many details, much fabrication required and a ton of skill. It's easy to hurt the engine badly by a poor or low quality installation or by getting overzealous with the boost. With cast-aluminum pistons and skinny little rods, the engines are limited to about 9-PSI intercooled. If you want more boost than this the pistons and rods will need to be replaced with upgraded parts. Fueling then too becomes an issue. You can't run a 15-PSI car on an FMU: you need bigger injectors and/or supplemental injectors to give the added fuel. Higher-capacity injectors are expensive and tough to find (for the V6 at least.) Supplemental injectors are always a "hack" on these engines because they can't guarantee even fuel distribution in the manifold. On the V6, there are 6 pistons...it only takes one of them to burn to turn the whole motor into a doorstop.
Twin turbos sound nice on paper but would be a nightmare to install. TKT makes a kit from what I hear but I've never heard of anyone actually installing it. You can't run any additional boost with TTs (the engine is still mechanically the limit), the mounting and plumbing would be, basically, twice as complex as for a single turbo.
A single-turbo, intercooled, well-done setup should be good for around 240WHP on a V6. On the I4, output in the 180WHP range shouldn't be out of the question (though I'm not aware of anyone who's dyno'd a turbo 4.)
Please feel free to add
value to this thread. I'm sure there are people with more turbo experience than I (Mici? Toastier? Rick?) itching to contribute and/or correct what I've written here.
Edit: In an effort to stave off some of these spurious turbo posts, I'm making this sticky. Value-adding posts will be kept, insipid, silly, stupid or incorrect posts will be deleted without prejudice. Perhaps if this thread condenses the boards' collective turbo knowledge (and there's quite a bit) into a single, concise thread, we'll see a reduction in the sickening repetition of the above-mentioned type of thread.
