1.What is the general consensus on this kit. Good Bad or indifferent?
2. how many hp it is going to give me ?
3. does anyone of you knows what brand are these turbos ?
4. is it great idea ?
5. how much it will cost to install it in car shop ?
6. will you buy it for your car or you will go with supercharger ?
No instructions, it doesn't show it even installed on a Mustang, so is there a guarantee that it will even fit? Also, if your brother's Mustang has a carb, this won't work. It's designed to fit to a fuel injected motor. So, add the cost of that unit to the cost of a fuel injection conversion.......
Those engines have more than what's in the kit on Ebay. If you run the output from the turbo into a stock carb, it will screw up the mixture. Under enough boost it is possible to lean the carb out enough that it won't run. The one describes an injector for use while under boost. That's because the carb isn't designed to function under boost fed down the airhorn. There are systems that enclose the entire carb so when boost is applied, but even those require the fuel pressure to overcome the boost yet not too much pressure while not under boost. A common way to turbo with a carb years ago was to mount the carb to the input of the turbo so it pulls air through it like it was designed, but those systems suffered from turbo lag and mixture problems. Also cut down on the problems from running the extra piping of a wet system, they would run directly from the turbo into the manifold. This would cut down on the lag and mixture problem, but the hotter mixture would kill a lot of the advantage of the boost. I'm not saying it can't be done, just that it isn't easy to do with a carb. If you're not an expert at it and know what you're doing, you can lean a motor out and cause damage. To hand a box of parts over to a shop and say "make it work" may take more money to get it running than what it's worth. There are supercharger systems on the market that will bolt right on the earlier Mustang and not have near the problems the turbo kit would.
the fuel injection will work. However get one from a 93 or older and you avoid the electronics issues. Then order the set up kit from Mustangs Plus....about 450....to 500. for the lines fuel pump etc. I looked into making my own lines to save money but the pump is the expensive part.
.....and I'm just giving you the high spots. This conversion will set you back before you even get to the turbo!

Do not buy that it has cheap china made turbos which are glued together and cheap wastegates.If the turbo kit is under 3k its probably not going to work for long and can take your engine out if it blows up.Why turbo a 289 why not build up a 302 or 351 to handle boost then have a turbo set up made for you locally or buy a blower.
