I applaud HKPRO5 thirst to do something different, but I have a feeling it will stay his pet project and not take off because of AC being through out. What is up with the AutoX video, the audio is not clean at all and sounds horrible.
I think there is a real market for a intake manifold/supercharger kit that maintains the AC, but keeps the kit cheap and simple. I think if you modified the intake so maybe the supercharger mounts under it or on the end of the intake manifold. I would mention that yes the stock intake makes a good bit of power for the NA FS-DE, but it has been shown that the 626 intake is perfect for a turbo because it is less restrictive and do not forget it does not have VTCS nor VICS. I think if you used a 626 intake manifold as a base and modified it with a roots charger for a start. To make a good product you need to get a custom manifold made or get a mold made. As for cooling, I have seen a heat exchanger in between a supercharger and the manifold on a Hyundai Tiburon GT that uses water, a electric pump and radiator up front. But that could be extra to contain cost and power (stock wussy motor rods are weak). So here is what i see as a rough price wise:
$344 for 626 intake
$400-900 for supercharger
$300 for special bracket and pulley.
$1044-$1544 total for seller cost, but not what the kit would need to be sold at to get work done. I figure if you spread the labor/R&D cost over a few kits you get the cost under $1,500-$2,000 for kit msrp.
I figure a header will definitely be a good idea, but not necessary. You could get a bung weld in for a wide band tuning, but why waste the money and get a header instead? I am currently working on what is needed to easily use the mx-6 2.0 4-2-1 header. I figure I just need a mx-6 midpipe/high flow cat (measured the header placement and it's 17" to the exhaust and the high flow cat with flanges will fit).
I would also recommend some type of tuning, but I would leave that to the individual to figure out and pay for. I see $400-$679 more and I would probably go with Split Second Fuel and Timing package for $679. So total cost to the end user would be around $2179-$2679 at most. I think most protege people would like this option because of the following:
1.) cheaper cost than turbo kit
2.) no shop needed to install
3.) safer for engine since engine oil and cooling does not get over worked by turbo cooling (not perfect because of rods).
4.) last longer before needing rebuilt
5.) maintains oem cats for legality.
What do you think Ken (protegegarage)?
