Gauging Interest: Turbo Kit

[RacebyDesign]

Hello,

We are doing some R&D work on a Boxster turbo kit.

Without going into too much detail, this is a quick summary:

*easy to bolt up turbo kit that will fit the 2.5/2.7 and most likely the S models. (still more R&D to come on fitment)

*turbo will be a quick spooling ball bearing unit, about 6 psi

*should be smog legal in 49 states

*liquid-to-air intercooled

*225-250 whp

Depending on what the community wants, we will tailor the final product:

Eg:

not intercooled -- low psi/no intercooler/lower gains / more affordable
intercooled -- higher psi/liquid intercooled/ high gains/ more costly

I say intercooled. If I'm going to spend the money, might as well do it right and get the most power.

Nice to see another Seattle person on here.

bumping this thread. Should I put it in the performance section?

Would a 12 second Boxster be considered "performance"

Assuming the kit meets your objectives, I can tell you a few things without a poll :

1. At $500 everybody will want one.

2. At $5,000 a few people will want one.

3. At $10,000 nobody will want one.

If you can find me one buyer for a million dollars I will sell 20 more for a dollar per kit.

Thank you for the input. I had the same thing in mind.

It seems there are two kits on the market currently. One utilizing a MP62 Eaton Supercharger (non intercooled), which is pretty small for even a 2.5 4-valve engine. Tuning on this is done via a Split-Second piggyback.

The other uses a Procharger C-1 (non-intercooled) with a reflashed ECU via GIAC software. No doubt its the better choice for upper rpm power.

A properly sized turbo should match the C-1 at the top end and destroy it in the midrange. I cant talk too bad about these units, Procharger's internal oil sump is a great design. I just with they didnt generate so much belt/blower squeal at idle. A great match for my business partner's 1988 5.0 track car...but it's quite embarrassing when showing up at the golf course in a Porsche.

An Eaton, while a great drivable setup, couldnt touch a similar turbo system. With an intercooler in the mix, the intake charge will be lower than the C-1 and MUCH lower than the MP62. I dont hate positive displacement blowers, my business partner's Focus SVT is pushing over 200 very streetable whp with a Jackson Racing MP62.

The thing that is most appealing for the Porsche crowd is that a good exhaust system will cost you a small fortune. When your done with the headers, cats, pipes, and tips you could have bought a full turbo system for another $500-1k.

Please keep up the great feedback. It's invaluable to us.

I would be interested in a modestly priced kit that provided modest performance improvements. That means my vote would be having a unit without an intercooler.

I just posted a note about a dyno run I did with my 2000 2.7L Boxster that has a TTP intake and performance chip. I am making about 198 hp with that rig, but it was expensive, over 2K for the chip and intake and installed. I would like to be able to massage a little more performance out of my engine without breaking the bank.

I also like the response characteristics of a supercharger instead of a turbocharger, but I cannt take the noise of any of the supercharger units I have heard. I have considered getting headers and high-flow cats, but as you say, that is a very expensive way to go to pick up a few hp, if any, just my 2 cents,

Hi,

A turbo kit on the Boxster is fraught with problems, mainly heat. Mid-engine cars don't dissipate heat like a front mount engine does.

Also, why don't you quit trying to hock your kit for free and pay sponsor fees? We have sponsors who pay to display to us and keep this site running. You're freeloading - pay or go away...

Happy Motoring!... Jim'99

Blake, I applaud your efforts!

I don't agree with Jim either, in fact, I would like to see real vendors on this forum so we can ask questions and get answers from the horses mouth so to speak.

In most of my reading here, I sense that most people are looking to buy something... or looking for advice about buying or where to buy for the boxster... and what boxster owner doesnt want more performance...

So even if you are selling, I see nothing wrong with it... and when it's no longer vaporware, PLEASE! come back and offer us a great deal! or at least ME ;-)

For the record, I would spend $10000 or more... I would be looking at $/HP when deciding which way to go... Gemballa biturbo is the most expensive option I have found, but even at $52000 (500BHP) I am seriously considering it cause it gives me a supersportscar... TTP at around $20000-40000 (330-450hp) is where I am heading... I am reading these forums and researching still and knowing you might have another option is good to know.

regards,

You would spend 10k on a Boxster turbo? You interested in any real estate?

yep... actually I am interested in real estate and I have made quite a bit of money out of it and continue to do so...

A boxster is a fantastic car that is simply underpowered... the fact that you can stick 500hp into it and turn it into something that competes with or beats a 911 says a lot for it's engineering.

I also suspect that most people who can afford Gemballa... don't need to save money from advice gained by joining this forum and so we don't see them...

As I said before, people should be discussing $/HP and not just what is affordable...

[RacebyDesign]

Lol, goodness.

When I first started this it was to generate some chat and see if there was a demand for it. I wanted to know if people with Boxsters were like most other Porsche owners...aka: they like turbocharger units.

I had no intent to become a turbo-Boxster sales mogul and one day name a city after me. I just think they are fun cars with a strong community of motorsport enthusiasts, not just guys with gold chains who rev at stop lights.

I have said before, until the weekend (like the 25th) or shortly after any concept of pricing is EXTREMELY vague. I have to talk to my other business partners, the shop doing the building, etc.

In all honesty this venture is simply to help break into the world performance parts and bring something to the table we can be known for. I am looking to make small batches and see a few owners with mild levels of boost with big grins on their faces. Lets think more in batches and less in the realm of Ford Motor Company popping out F-150's by the crate.

If there is a demand and it can be done successfully (high quality, good results, decent price), we would like to introduce an intercooled kit to produce a max of 6psi with a liquid intercooler. ANY production engine that doesnt have pistons made of particle board can stand a conservatively tuned 5 or 6psi not intercooled. With an efficient intercooler this is very safe because your dropping the charge temperature and consequentially losing 1-2 psi through the intercooler. So only 4psi makes it to your throttle body and its colder than a Corona sitting in a bucket full of ice.

Bear in mind that a 1zz-fe is a cast piston Corolla engine that is notoriously weak. Stock motors can take a little boost, look at the Mazdaspeed Protege.

Anyways, long story that should have been very short. I am not looking to make alot of money on this particular project, nor put together some cheesy welded shop class nightmare.

For the record: I dont want to trick you, I dont want to get rich, I dont want to blow any engines up, and I definitely dont want free advertising.

Until I have some good hard facts I appreciate the feedback but please treat this like any other thread. Talk about it, think about it, laugh about it, etc.

Wait until our emblem appears on the side and we have a part number before you do anything.

Cheers,

PS: Because are selling other parts and redesigning our website (it is very rudimentary), I am contacting the moderator of this forum to join as a sponsor.

It has been my intent the entire time to find Boxster forum to join (and pay) for this reason. The only reason I didnt earlier is because we haven't even started selling to the public yet.

I will make an introduction thread when this happens.

[ohioboxster]

Oh no mister, theres going to be a city named after you wether you like it or not. I wish you luck.

[mnavarro]

If you have something for 5K I would go for it. I would pay 5K to get 50-70 hp more. I have installed everything on my STI and if it's an easier install I would like to do it myself. You probably should go intercooled. You will probably need injectors. Maybe you can get around some of this cost by increasing fuel pressure and providing a different fuel pump.

[Cloudsurfer]

Personally, I don't believe in forced induction without intercooling. Are you looking at a single or twin turbo setup? Single turbo on a flat motor like this strikes me as a plumbing nightmare.

Unfortunately, at the end of the day, I think the SC kits make more sense on these cars, if at all, as the M96 has somewhat proven to be an iffy motor, and as much as I'd like more power out of my S, I'm not willing to risk blowing up the motor to do so. This is why I am planning on a 3.6 sooner or later.

Best of luck to you.
