hey whats up guys its me again. I finally went for it and got a y8 swap on my 89 rex. the power upgrade is pretty good over the stock engine. i like it but i want a little more power. I was looking foward to turbo but i dont think it would be a good idea since its my daily driver so i was thinking about super charging it. does any one know if its a good a idea. any comments welcomed

which of the two is more cost friendly?
Hmm....ok here goes.
My personal .02 will tell you that Turbo is the only way to go,but opinions are like "********" so everyone has a varying one. :D

The only real Supercharger setup that I'm privy to is the Jackson Racing one and a new setup will set you back round $2600 easy.Yeah I know JR sells em for $2K,but dont forget tuning and all the little expenses that goes with boosting a vehicle.
I however went turbo and put my whole setup on for under $1K.
:looks around: I know that some people frown here on DIY turbo setups,but if done with a little diligence and a LOT of reading it can go a long way.
I also personally think that a turbo setup has more potential than a supercharger.

My thoughts?.................... turbo mang! :D

Fellow member Matt Miner has a ZDyne Gold SECU for sale in the classifieds that would get you WELL on your way to having EITHER run 100% reliably and smoothly ;)

btw, my vote goes for turbo... the adjustability is second to none, and upgradability is great!

I plan on supercharging my sohc vtec zc (basically a z6)...I know I could make more power with a turbo, but this is a daily driver and I'm digging the instant power anywhere in the RPM range with the supercharger. I'm not looking to have the fastest car out there, just make my car more fun for daily driving and keep it reliable. I'm not really interested in piecing together a turbo kit (although I respect the DIY turbos done on the cheap), so I think it will work for me.

i have the JRSC on my A6. Stock kit sucks 6 psi is not enough so you will immediately going to want a pulley upgrade. With this you will have to go with a fuel managment system and a tune to keep it safe. JRSC are a good mod when they have been upgraded i had mine stock for about 4 weeks before i started tinkering. they have great low end power but it falls off one the top end. My A6 SC is easily faster than B series swapped CRXes but it took tuning to get it there.

And then you hit another brick wall... :lol:. You can only overspin a SC with a pulley 'so fast', before you wind up over-revving it and making it blow out of its efficiency range. So basically, it only has so much potential, unless you start buying different compressors, and modifying things, and spending a LOT of $$ to make all that happen... And you still aren't better off necessarily.

So are most basic turbocharged setups :)

And then here lies another problem you will have to defend youself all the time if you run a S/C. I run 10 psi I have had no problems with detonation and it runs just fine. I am also tuned. The only problem is as said above heat because there is no intercooling so cant run as much timing as I may want. i would say anything above 10psi on a stock eaton m45 is counterproductive. For less than people think you can port these blowers for $495( not overpriced endyn) and lower your temp and increase efficiency. There are also coolers made by LHT but these will cost some money. Since I have a A6 the y8 crank pulley was significantly bigger so this upgrade cost me a whole $10. A lot of horror stories about these blowers come from people who run the fmu and stock inj and then try to up the boost. This not only sucks for S/C but is also a crappy way to run turbos. With free programs at PGMFI.org and the price of dsm 450s running a fmu is stupid.

I hope I helped you more than just saying dont buy it and get a turbo. Make up your own mind also if you want more info there is a 200+ thread on Honda-Tech about JRSCs.
