ok so im new and i need help with turbocharging

[squirrels06]

i have a 93 daytona with the great ole 3.0 engine and the a604 tranny and the tranny was recently rebuilt about 3000 miles ago but the motor has alot of miles on it (200000)...but it runs just fine with no problems what so ever sooo ive really been looking into turbocharging it, nothing too big really just wanting to get it around the 250 whp range or so. what all do i need to do to get there? i have a limited budget but i think it could be done...is an engine rebuild necesary for me? different injectors? fuel pump? a full list of necesities would be GREATLY appreciated!!!! ive been researching this for a while now but i still dont have any answers to the questions i have asked . please somebody help me out on this!!!!!

Rebuild that engine for starters....read up as well. Corky bell has a good book and there are other good turbo books out there. 250 horse is very doable.....injectors, fpr, fuel pump, id for with megasquirt fms. You're obviously going to have to do some fabbing as far as metal is concerned. Id save money and do more research....then when you rebuild go with forged pistons but thats just my opinion...not that its a necessity or anything...i know brent had problems there. There are many odds and ends to do as far as running an efficient setup. Thats saying if its going to be a daily driver. There are alot of things people dont think about when they are building there turbo setup...oil draining....oiling for that matter turbo sizing....the list goes on. In other words...keep reading and asking guys like brent and wink for advice and check out kelly-mulhern performance....Mike and ed know what they are doing.

thanks for your input its definatly a big help! i guess im gonna have to hit the books then. brent and wink... i guess i need to ask you guys for help now!!

[irocelectric93]

Brent and Wink both know their stuff....Brent is Ondonti in the boards already built a t3/t4 hybrid that ran high 13s with 285 horse....and that was in a spirit. Wink is building a twin turbo setup....both of them are very knowledgable. Good luck man im working on my turbo setup as well.

if you have any specific questions, don't hesitate to ask. Just send me a PM or get up with me on AIM or Yahoo Messenger.

Ondonti/brent is retarded when it comes to electronics!!!

[mwinkle353]

Oh come on now. It doesn't take a rocket scientist to work a multimeter!!!

[NA2ndgen]

I know exactly how Ondonti feels right now. I was terrified when I pulled my lower intake, plenum etc, and the exhaust manifolds. It was my first big DIY. By the time I got to replacing the O rings on the water tube, during reassembly, I began to feel confident though, and using hi-tack was a PITA. Had to say that, and thank God for the 'Rob's Corner' website too!

Hang in there Ondonti.

PS

I know how to use a multimeter.

Thought maybe that would motivate you a bit.

what kind of injectors should i look for? what will work in the car impedence wise? also i read on the allpar site that the stock fuel pump was the same as the one in the turbo car so why might i need a bigger one since im not really pushing for too radical of a hp range. what size of turbo should i be looking for? also should/will i need an intercooler to achieve my hp range? and when i rebuild should i just go with the cast pistons or go out and get forged ones and look for bigger rods?

[mwinkle353]

You'll need high impedence injectors. Upgrade units for the ford mustang is a good place to start. I'm using Ford Performance 30# injectors in my 93 Lebaron.

Fuel pump is identical to the turbo pumps of the same years. Honestly, depending on your final fuel setup, you'll max it out around 250-260hp. That's about 8-10 psi on a 3.0L with boost.

Size of turbo is varying. But I'd be looking for a Mitsubishi 16G or 18G, Garrett T3/T4 hybrid with a 50 trim comressor mated to a stage II or III turbine wheel in a .63 A/R housing, or even a Holset HY35 would be a decent choice.

An intercooler for any turbo setup is "HIGHLY" recommended. Especially for a NA to turbo convert.

For reliability, go with forged pistons. But cast pistons will be just fine, as long as you keep detonation at bay. Rods are strong enough for anything you can throw at them. The 300hp 3000GT's have the exact same rods. And they are doing well on some of the 500+hp motors.

Turbo 3.0 on the boards had a 16g turbo which was what i was going to go with for a while....he was spooling around 2600 rpms....not sure when he was reaching full boost...or if he had cutoff or anything. Im going with a t3/t4 turbonetics...50 trim stage 3 turbine with .63 a/r housing. Thats me....im going with like 350-400 horse range...hopefully. I would go with forged pistons....just for reliability....one advantage to a 16g however is that ...its a little smaller than a hybrid...which is something im running into a bit since my iroc has alot of crap ...abs etc. Keep researching...thats what im doing! Always more to learn.

how do i run oil and coolant lines to it?

[c2xejk]

Oil supply side I used braided stainless. Oil return I used a combination of a custom pipe and reinforced silicone...

For the coolant I used the old pipes and some standard coolant/fuel hose....

[mwinkle353]

Tap the oil from the oil pressure sending unit. Oil drain will need to be sent to the oil pan. Modify the oil pan for a drain fitting (make sure it's above the normal oil levels).

Coolant line... Just Tee off of the heater core hoses.

I believe I documented most of this on www.kmperformance.com... choose "current projects" then "Turbo header prototype"
