Yea so i've said it in the past and I will say it again, I am no mechanic lol.. that's why i am here i am currently looking to rebuild my 2000 4.6L which is pretty much stock at the moment. I let a friend (at the time) drive it and he took out a piston rod im sure. so I was looking to perhaps bore out the cylenders, new roller rockers, pulley sys, timing chain, springs, fuel rails,crank, cams, pistons/rods, etc. and.. a TURBO.. I'd like to take my mustang to Road Atlanta sometime soon and open it up. I have plenty of lower end tourque, so it'd be nice to try out a turbo instead of the supercharger. plus i noticed a lot of problems with superchargers from going in and out of the throttle in the nhra, so im not sure if i'd be wanting one tooo much anyways. love the sound tho.. but anyways, anything anyone can tell me to possibly look for while building this around the turbo would be greatful. i dont want to bore out my cylenders and then find out i can no longer put a turo on it or anything lol. thanks in advanced everyone. hope this helps out a lot of people in the upcoming days

and as far as the turbo goes, i was posssibly thinking of getting something like eBay Motors: Turbo Power Pack T70 650hp Ford Mustang 4.6L 5.0L Kit (item 170298565526 end time Feb-05-09 22:38:46 PST)

it's cheap and will hopfully do the job.

Your motor will be fine with a turbo even if it has to be bored out.

For turbo selection I would not buy that eBay one. For one it is a no name turbo and waste gate so it's like a craps shoot but you'll most likely lose. Second it is just a turbo, intercooler, waste gate and lines. You will still need a hot side and a cold side.

Look into reputable companies like:
Mustang Turbo "tuner" Kits : Pony Down Performance, turbo mustang kits & parts
B&G CUSTOM TURBO FABRICATIONS

Remember you get what you pay for.

Thanks Dufkis!.

im still curious though.. so i can pretty much bore my engine out to whatever I want and the turbo will always still be compatable ? cause i was under the impression you have to have a perfect match.. lol and what the hell is a waste gate exactly, and it's purpouse. i really would like to learn a lot of this stuff so I'm not just installing 'another part' . and also, hot/cold side??

i really dont kno much about vehicle motors, i never really had to work on my mustang(s) before, though, i could take my dirtbikes apart and put back together with a blindfold lol.

You can only bore a motor out so far but on the newer mod motors you can't really go huge with them so you will be fine. A properly matched turbo will work fine with a stock or over bored motor so no worries.

The waste gate is what keeps turbos at a specific boost level. With out one the turbo would keep making boost until the motor blew or the turbo self destructed. Here is a little more info Wastegate - Wikipedia, the free encyclopedia

Hot side- the parts where the exhaust gasses are, headers, crossover, downpipe.
Cold side- where the boost is

Masterpower makes a fine turbo. do not skimp on a turbo, or you will be rebuilding it soon.

What the heck is going on here? See below......

Damn double post! See below......

You need to properly spec a turbo system to match your motor. If you threw a rod, you need to see if the block will clean up before going out any buying a turbo system. You might be looking for a new block. There are several factors in which to spec at turbo. You need to choose an island of efficiency rather than just buying one or you will either have lag with one too big, or spool too soon with a small turbo. Once you get an idea of what your target compression ratio is, then you need to figure out what the flow characteristics are going to be for your heads and intakes, only then should you spec out a turbo. Efficiency is the key. Some people forget that boost is a measure of restriction, not efficiency......

Example: I run 17# of boost at 641rwhp, while Matt runs 30# with the same hp. Therefore, my system is more efficient because I can run the same hp with less boost.......

thanks yall, so much. so the plan is to now strip down the block to see if it is rebuildable after the rod problem. i just thought i should build the engine around the turbo sorta. but now knowing with my year engine i should be fine no matter what work i do to it, as long as the turbo's specs match with mine.

hot/cold side is too funny. just never heard the phrase before.

so does the wastegate also function with the blowoff valve?

i really did want to get a new block for my mustang.. i know she's willing and so am i but it'll probably just end up into a way long project. i just think im going to stick with a stock block.. hell i should be damn happy once that turbo is on lol. may not be DOHC but **** it lol. perhaps i will rebuild one on the side, specifically meant to be a long project.. I JUST NEED MY FIX! miss my mustang and going FAST!.. drivin a damn chevy 1500 rofl..

No the wastegate controls how much exhaust gas goes into the impeller to keep boost at a certain level.

The blow off valve releases the boost pressure on the cold side when the throttle is closed.
