Completely agree with you, Kirk. If this happens, it'll be an LN based engine (we're a dealer for LN as well) with probably 9 to 9.5:1 pistons. We've got a guy who is interested in doing this on his car, so that just might be the test car :)

It might not be a bad idea for the OP to read this:

I am a fan of forced induction...just not really on these cars. It certainly can be done but I think the cost/risk outweighs the benefit. The only SC car I know that is still running is forum member pk2. It is a TPC on a 2.5l motor. I have not talked to pk for a while but if I recall he had to get pretty creative regarding installation and tuning. Last I heard he was not satisfied with his DME tune and was running/mixing 100 octane racing fuel to avoid detonation. This may have been solved by now.

An ideal FI platform would be a stout engine block with forged 8/1 pistons, billet crank and rods, a nice big fat intercooler, plenty of room for all the necessary plumbing, and a race developed ECU that allows easy trackside tuning for Ign timing, A/F ratio, boost etc. The Boxster has none of the above. To get the car to this level might cost $30K+. Penske or Farnbacher have those kind of funds to play with but I don't. I would rather just buy a nice GT3 and go racing.

Am I correct that the Turbo Werx/Turbo Kraft turbo kit for the 3.2L is the only kit on the market right now for the Boxster?

I think the TPC supercharger kit is long defunct.

I think the Imagine Auto supercharger kit is also gone, I can't even really find their website now.

It looks like the Turbo Werx 2.5 twin turbo kit (which is what I think Gary in BR is running) is also gone.

Forgetting about this eBay garbage, which really isn't even a complete kit, are there actually any other turbo or supercharger options out there now besides the Turbo Werx Boxster S kit?

Kirk

I think you can do it, I just think the quality of the tuning and parts in the kits that have been available have been sub-par. On the 996 side VF Engineering has sold over 500 of their supercharger kits that run a mild 6 psi. People are tickled with them and they seem very reliable. But VF does it right. They supply larger fuel injectors and have the ECU reflashed with a custom GIAC tune. I think that's the real key here is that they had an industry pro like GIAC tune the thing.

TPC used a 7th injector and a Uni-chip piggy back ECU for their 996 supercharger kit and now they've followed suit and switched to using larger fuel injectors and a custom ECU reflash like VF.

Based on what I've read the IA and TPC installs were crap and yes tuning was an issue too. Just look up Gary in BR's dyno chart comparing his IA setup to his TurboWerx setup. The IA supercharger was making almost nothing over stock!!!

It looks like TurboWerx might have things right with the current Boxster S turbo kit they sell - low pressure (like 5.5 to 6 psi) turbo with larger injectors and a custom ECU reflash. If their tuning is good (and that's a big IF) that should be good for a reliable 100 HP, which is what they claim. If the 996 and VF Engineering guys can do it reliably with the 3.4 and 3.6L engines, then we should be able to do the same, if not more, with the 3.2L which is theoretically stronger!

Kirk

IA is no longer in business....

It is worth noting, that on the M96 motors, it's relatively simple to update the sleeves (LN), very easy to update the rods (R&R, Pauter, etc), pistons (JE), but not the crank. These motors unfortunately don't run a forged crank, and finding someone to make a forged crank for these motors would be cost prohibitive by itself.

As to how long it takes a turbo motor to blow up, a significant portion of that depends on how well it's tuned.

I will say, however, that I think a proper turbo kit, done within the realm of sanity, is possible on these cars, and that no one to date has done it right.

I just talked to TPC who only has a single turbo setup at present that seems to put out good numbers. They do not make the supercharger kit any longer.

I had an MR2 at one time and the engine compartment and trunk are very close if I remember correctly. anyways I would love to see this, and it has been done on the MR2. I'll just throw this idea out there. Rear mounted, Vent the boxster's rear trunk lid, maybe some scoops, push pull fan mounted to intercooler. This is not my car. Somebody do this. Just not me, mines to pretty. :)

do it

Yup, that would be the way to go... Put a forward facing scoop on the trunk lid and vent the IC out the bottom. Like you though I don't really have the ambition to do that on my personal car. I love it too much the way it is. But if the engine blows someday, maybe...

There was a guy in Canada on here who was doing a trunk mounted dual IC setup for his turbo Boxster. I'm not sure what he was doing for venting though, it wasn't like this (more ideal) setup.
