So the last 2 weeks have been some really bad ones for me and my S2K. Starting the week of Thanksgiving my supercharger died on that Monday. It had been making noise but I thought it was a one of the pulley's(tensioner, idle, etc) bearings going bad(this was also kraftwerks thought). So I changed the bearing and when I reinstalled the bearing it was still making noise and sure enough it seized up shortly after that. Well I had to order some bolts to reinstall the factory tensioner and bypass the the supercharger so I could get the car running again. This took another week because of the holiday and the I didnt get my car running again till a week after Thanksgiving. I spoke to KW and they are basically telling me that a new blower is $2000. Well to add insult to injury my car got hit by some assh&*e on Thanksgiving while I was out eating dinner with my g/f's family so now I have a huge dent in my door that also needs attention.

Honestly I dont really like superchargers and do not feel all that great buying a replacement blower since this one all lasted about 20k miles. The previous owner only put 7k miles on it(i verified the info with a friend who did the install). I am very meticulous in my maintenance and care of the car. A little background I bought the car from another S2ki member a year ago and it was already boosted. I have thought about pulling the kit off and selling it and going turbo. I am not really looking for anything crazy power wise, just 350-400hp basically what I got from the KW. I saw a Godspeed kit Turbo kit and spoke to them they are willingly to let it go for around $1800 maybe a little less. The kit doesnt seem terrible it has a Turbonetics turbo and revhard manifold and a Tial wastegate. Those are really the things that matter quality wise to me and they seem solid & decent. I would still need the tune and some other small items but they really wouldnt be that big a deal. I work in the industry and have plenty of hook-ups for all that.

My question to you guys is what do you think my best course would be at this junction. Replace the KW blower and be done with it. Sell the kit I have for cheap Obvisiouly someone would have to buy a new blower(it would still be cheaper than a new kit). I was thinking letting it go for like $1500(not really sure what it would be worth have to see what people are getting for the whole kit used) & Go turbo (as explained above) or just go back to stock.

Just looking to get some opinions and maybe different points of view that I haven't thought of. Please no flaming or trolling.

 

if you get a godspeed kit be prepared for plenty of down time. those ebay kits are junk. if money is the issue get another kw blower and sell it in a year or two as a complete kit

 

Joe out of curiosity what makes the kit junk. It is a turbonetics turbo, revhard manifold and tial wastegate. Nothing sounds junky. This is why I am curious to see why people consider the kit junky. I am aware that there are better kits, but for a basic daily driving kit I really do not see anything bad with it. I'm just asking, do you have personal experience with the kit or is it just word of mouth?

 

because its a bunch of mid level parts put together. its not a full working complete kit. your getting mid level everything so you can expect problems and issues with mid level equipment.


$2000 is stupid for a new blower as you can get a used V2 kit for about 2500. If i were you I would sell the kit and transfer to another kit or go turbo. Im sure for the right deal somebody would be willing to fab a custom blower to your set up as well. no cheap options, but selling the kit would save you the most money in the long term.

 

Since there is no other blower compatible for the kit and you will likely be hard pressed to sell it without the blower, I think it makes the most sense to buy another Rotrex blower and run the car. Down the road in a year or so after you have saved up some cash towards something else, sell the kit and make another 3k or so. I don't know what size pulley your running, but make sure you are not over spinning the blower, as Rotrex units are especially sensitive to rpm/heat since by design they are spinning nearly twice as fast as the typical Paxton centrifugal blower, without twice the benefit, but rather arguably a shorter lifespan. Ive put well over 100,000 miles on my old Novi 1000 before I needed bearing/seals and that was speed up because I was over spinning significantly towards the tail end of its 7 year age.

 

So it was the blower bearing that failed after 20,000 miles? Over how many years? And how often do you have to change the blowers oil? . And was this done?

 

My first setup was more of less a god speed kit.

My current setup is in my signature. Although the god speed kit used good quality parts and it was very reliable people on this forum always recommend top of the line parts such as a ball bearing billet wheel turbo and a tubular turbo manifold. Every one with that type of log manifold kits always end up upgrading some time down the road. Although the log manifold spools much faster than a tubular manifold it really holds back the top end really bad.

I have had 3 set ups. I gained 60whp going from a log manifold to the track forged tubular manifold. I gained another 60whp going from a old school garrett t series turbo to a new garrett gtx ball bearing billet wheel turbo

You won't be happy with the god speed kit. Replace the super charger over the god speed kit. Only go turbo if your willing to get a high quality tubular manifold and a quality billet wheel ball bearing turbo.

 

Junky, I have the high-boost kit and it has the KW pulley for that kit, at the moment I cannot remember the diameter. If it is overspun its KW fault..lol

John42td, Yes the ebarings failed the blower was just over 3 years old and I changed the blower fluid once because it had been 2 years since, it was installed and the blower only had 7000 miles on it when I bought it. I followed all the steps for replacing the fluid and priming the blower.

Riceball, I appraciate the input from someone who has experience with the kit. I am aware and understand the limitations of a log style manifold on the S2000 and realize that there are better Turbos and manifold designs, but as I said I dont really want more than 350hp. I really dont plan to do much racing maybe the occasional event but that is not the goal. As long as the pieces & parts are good quality and will last that is really what matters. I am just looking for something to replace the blower as I really dont want to spend $2000 on something that I have little to no faith in and the warranty process did not make me feel any better. So at this point i just think that putting the car back to stock and moving on.


Thanks for all your input.

 

Why not peace a kit together like a Borg 257 or something along that is 600.00 then get a pfab tubular log mani is 439.00 shop hard and get a tial bov and gate for 450 or good used for less then a mishimoto intercooler for 175-225 and universal pipeing kit for 100 then have exhaust fabed up maybe 2200 when done and all parts are well known in s2k world
Don't think to many bad things can be said about it

ahh, KW customer service at its finest. if you shifted at 8600rpm, the blower was overspun. it was KW fault. they released a revised limit of 8200 if i remember right. apparently, the blower is super efficient until just barely passing its rpm limit, then it implodes.
