I saw so many posts about supercharging KA. Most of them lead nowhere. Moderators, Maybe we should make a new forum where all the research and information will be contributed in regards to supercharged KA. I'm very interested in putting together a kit and have good connections for mass fabrication for cheap (on existing design).
KA24DER souns like a good name for a forum like that.

As far as price, I really don't know yet. I havn't looked that far into it. I'd have to sit down and do some designing for fitting the supercharger to the engine first. Gains should be real close to the gains seen by turbo kits. Boost levels will be the same as well, just depends on your engine mods as to how much boost you can run. The C-1 unit is made for imports, they use it in the kits for Hondas and such. It can supply enough for 625 HP according to Pro Charger.
Cory,
My dad is a chief engineer at the factory back in russia that produces rockets that cary satellites to the orbit. They have side business where they custom manufacture (25+ units) anything.
Their last client ordered 50 titanium mountain bike frames. They used exact Litespeed frame design, space-quality titanium and laser weld. Price was around $150 each. Compare it to the cheapest titanium frame found here for $800.
I'm pretty sure those people can even make their own titanium superchargers. They make rockets after all

I think it would work great and amplify the KA's low end torque. I've been looking at my car some, placement of the unit will be the most difficult thing. It would take some time to fabricate a bracket. I'd like to put it on the driver's side but the power steering pump is kinda in the way. There looks to be a pretty good space under the alternator though. I'll take a closer look when I remove my fan and shroud to replace my front seal this weekend. Hey, JDM, I drove....and could have bought....a '98 LE 5 Speed.....now that's rare!! The guy wanted too much and the car had been wrecked and had the 95-96 front end. Only had 23,000 miles though, just not worth what he wants for it.
I would make an intercooled kit for sure!! But, it can be optional. A BOV is a really good idea, however, a bypass valve may be needed as the blower may not pass enough air through it at idle. I know Mustang kits come with a bypass valve, does the same as a BOV only it allows air to bypass the blower under vacuum. I would probably start with a kit for stock KAs, about 6 PSI, just to be safe and reliable. At this boost level, I don't think larger injectors would be needed (someone correct me if I am wrong) An FMU would do the job just fine when teamed with an SAFC and a good Air/Fuel meter. I would definitly upgrade the pump though!! Some of this may change when and if I do this, as I may find more would be needed.....but, I'm almost positive this work fine for a stock KA.
Stage 2 would be more boost, bigger intercooler, and complete fuel upgrade with boost being around 12 or higher for engines with forged internals. Maybe offer a few different pulley sizes so that boost could be customized to your set up.

Could you do a 6psi setup - nonintercooled bolton for the stage one setup? Seems like this would be an extremely easy bolt on for starters, then upgrade to intercooled/bov/whatever to get up to 10 psi. After that, forged internal would be a requirement. I have talked to some shops about turbos, and they would work fine on a stock ka at 6 psi. Just need a fuel pump that can handle it. No safc necessary.
The easy starter kit would be cheaper and easier to market if your into that kind of thing.

Yeah, that's the direction I would go. I was just adding an SAFC b/c I would want one to do some fine tuning. The intercooler isnt a big deal, very easy to install, but, I could omit it for a bare bones kit. As I said earlier, I'm gonna look at the car this weekend while I have the fan and shroud off so I can get a better look. I'm sure I can come up with a bracket design and all.
Hey, JDM, it is a shame that 98 was wrecked at one time. It wasnt bad though, just a slight hit on the driver's side corner. They had to repair the front part of the inner fender......the seam where the coolant resevoir is. He just didnt have the S14-B parts, so he put parts off a 95 that he had for a parts car on it and painted it. The car could be nice with very little TLC, but, at $9800, it's just wayyyyyy too much.

Cory- Going rate for a 98' SE 5spd is 11 grand. 9800 doesn't sound too far off base if it looks good and was repaired properly. And what exactly is an s14-b? I thought the 98s were s14-a's? Educate me.
This kit sounds like it is coming along well, i am going to hazard a guess that the kit would cost around 3000 bucks for the bare bones to make it work?

I thought 95-96 were s-14A and 97-98 were s14B?? Maybe I have it backwards?? Anyhoo, the car has the 95-96 front end (lights, hood, fenders) and not the 98 front that it should have. The only way you can tell it was wrecked is the paint in the front looks new. If you had the car cut and buffed, it would be ok. It's pearl white with cream leather interior and the factory wood grain dash. It has a couple small cuts to the padding on the passenger air bag. The car drove great!! I just didnt want to spend that much. I got a sweet 96 that looks like brand new!! Red with black leather, ABS, all options, 5-speed, H&R springs, N1 single, Brembo rotors, Injen intake, Konig 17" Imagines.....paint is only 6 months old, antenna was shaved. It's sweet!!
I could have the SC emblems made very easily That wouldn't be hard at all. oh....and that 98 is an LE not an SE.
