It's not a ripoff of the Greddy kit, it is the Greddy turbo kit. Greddy doesn't manufacture their turbo kit in-house.

So they're overproducing at the factory and spun it off into another venture?

I don't know what kind of contract SBD has with Zage, but I'm fairly certain it's not "SBD gets to sell all the excess turbo kits."

Wrong forum here I think

Sbd is a good company distributing for a not so moral company. OP doesn't know enough about cars to go FI and needs a bigger budget. I'm going to bed now.

That's interesting. From what SBD has been saying (about visiting Zage in China, etc.), I assumed that Zage had simply copied the design of the Greddy kit and began manufacturing them with some of their little additions to claim it is their own kit. I hadn't heard that they cut out the whole process and just straight up stole from the Greddy-backed manufacturing line. Where'd you hear that from?


Find a good enough shop and have deep enough pockets and you don't have to know about anything about your car. :bonk:

This was the impression I got from SBD when they first introduced the kit. Now you have me second guessing.

Be born with enough money and you don't have to know anything about anything.

Ugh.

Anyway there has been two threads recently where greddy said zage does not make their kit. That zage copied it. Zage is in china and greddy says there's is made in Taiwan. Sbd smartly will not comment and now makes it very obvious they are a zage distributer and its not an SBD kit. Just something sbd sells. That's a smart way to avoid being sued. One member does claim his zage kit sold by sbd has a greddy elblem on it that was ground off.


I feel like I'm one of the last people to build my car on jackstandsnin my driveway.

Oil pumps can fail on turbos, and they require tapping the oil pan, but a self-contained system requires its own fluid change and watching of fluid level. Cooling is also better through the engine oil. If a system has its own reservoir and cooler, it needs its own pump, lines, radiator, and so on. Lots more failure points. More importantly, there are superchargers that tie into the engine oiling system, and there are turbos that use their own lubrication. The whole point you made has little to do with the supercharger vs turbo question other than, maybe, what is the preferred method of cooling, and what is offered in mainstream kits.

In a basic theoretical sense, it comes down to heat management (Turbo) versus more mechanical parts (Supercharger). In practical terms, it really comes down to the quality of the design and installation and whether the needs and capabilities of the driver are met.

I would do more homework before deciding based purely on input on this thread.

Start with learning the basics of how an internal combustion engine works (air in, fuel in, mixture compressed, mixture ignited, piston rotates crank, exhaust out). Then learn how both FI solutions work so you can see what's being offered on the market so you can better process their designs and user feedback related to your needs.

You don't need to have years wrenching on your car, but I would recommend a basic mechanical understanding of how your engine works before going FI.

A few key things. Pay particular attention to how compression ratio and boost with valve timing and duration affect detonation and pre-ignition based on the fuel to be used in the car. Then look at the whether the stock rods and pistons (then transmission, axles, wheels and tires, etc.) will support your desired power output.

you can generally get a "tuner" kit for $4200. its about $5000 with a tune.

with that kit you're looking at 250rhp

i had an exhaust and we maxed out the fuel pump on the dyno at 260rhp.

throw in a fuel pump, and aftermarket injectors to get the most out of it.

if you want a little more, you'll need a smaller pulley.

for even more, E85

thats been my experience. i currently have everything but E85 and she's a blast to drive. its great for DD and having fun on the way to work or taking a spirited cruise.
why do you have to be an asshole. i had no clue how boost works when i first got my car. i started asking questions and reading up on the forums. i have a basic idea now and pushing 14psi. however im no where near an expert and im still learning every day.

we are here to help each other out, not bash.

Ecutek with racerom is 800 $ not including dyno time.

thanks guys for all your helpful comments. Looks like I still have a ton of research to do. ill try to find a decent tuner shop in Vancouver BC and ask them for a advice also. Thanks again gentlemen.
