My first thought is since it is used there will be surprises that you hadn't thought about like missing something extra you need that will end up running the cost up.

Kits are generally more complete.

I am reluctant to put power adders that raise the cylinder pressures so much without upgrading the short block or the head attachment methods like gaskets and bolts. My experience is that when you don't do it right you end up causing other things to break causing the frustration and cost to go up.

So why is this guy selling it?

My next door neighbor has been building engines for 20 years and used to specialize in the Ford mod motor. I have talked to him a lot about that motor because I was considering getting another Mustang before I bought the Vette. The 2 valve mod motor has some really really bad flow numbers. If it were me and I were willing to put a couple of thousand dollars into an engine I would put a good set of heads on it first. You can achieve almost the same horsepower numbers you are looking at without causing other problems later.

My neighbor said you can convert a 2V motor to a 4V motor. I can't seem to find anything on that. But a really good 2V head flows about 230 cfm per cylinder where a 4V flows about 320 cfm. If you can do that you will surpass what a supercharger at 6 psi will do.

This is all I have found on the conversion
http://www.allfordmustangs.com/forum...questions.html

found this http://www.allfordmustangs.com/forum...sion-dohc.html

Boy searching for "conversions" on that site brought back a flood of memories on all the the stuff I did to my 85 mustang GT. People were asking questions about stuff I had done 20 years ago.

All just some thoughts and ideas.

FYI I have used these guys so many times they used to know me by name. They used to have an internet site www.stangparts.com but it appears they have gone to Ebay sales online only. They have a showroom in Winder Ga. It is a junk yard that specializes in Mustangs. They also sell new Ford Motor Sports parts.

They can probably sell you everything you need to convert your 2V engine to a 4V engine. They'll just take it off a wrecked Cobra.

Back in the mid 90s I bought a set of seats from MPS out of an 85 GT to replace the seats in mine. Of coarse the drivers seat was all I really needed but you can't by just that. So I ended up with a perfectly good passenger seat. One day I was walking between building at work and when I passed the dumpster I saw the base of a task chair sticking up out of it. I walked over to it and it was a chair that the back had broken off of it. I got to thinking all I needed was an adapter plate to adapt it to my Mustang chair. I went and got a 1/8" piece of aluminum and transferred the hole locations and drilled the holes with a drill press in the shop. I mounted the Mustang chair and it worked perfectly. I have been using this chair as my computer chair ever since and I'm sitting in it right now. It looks impressive and the kids and cats fight over using it all the time. Nothing like having a 6 way adjustable car seat to sit at your computer on. Many people have said I need to go into business doing this conversion.

Words of wisdom. I would never add a power adder to anything other than a freshly done purpose built motor. Why? because we enthusiasts tend to use that power and the motor needs to be built to withstand the increased stress.

That all goes well before whether the used parts even work properly.

My bro' in law had a Procharger (I believe P-1SC) on his 96 Mustang for nearly 10 years. The Mustang motor responds very well to supercharging, mainly because of the low 9:1 compression ratio. It's much easier to do than on an F-body, which has 10.4:1 compression.

That being said, I would not supercharge any motor unless I first did a compression test to check the cylinders. Then, I would do a leak down test to verify the heads are in good shape. If everything passes, supercharging can be done relatively safely on a Mustang.

You're going to not want to skimp on the intercooler, as this is the big difference between adding safe power and running on the edge. The bigger the better here.

My bro' had his computer reprogrammed to take advantage of the change as well. He did not make the kind of power you're thinking though. His RWHP increased to about 330, up from about 210. I'm not that familiar with Ford motors, but I believe the motor you have is only 260 hp. That would translate into about 230 hp to the wheels (optimistic). You're never going to add 170 WHP without running the risk of blowing the motor. It can be done, but like others have said, you'll need a lot of boost and can run into problems with the stock bottom end.

If you want, contact my bro' here: http://www.superstallions.com/

He's one the founders/administrators, and goes by the handle MDecillis. His wife (my lil' sister) is also on there. She has (supercharged) 03 Cobra.

From what I know about screws, they wear faster than centrifugal units. As they wear, the boost drops. If the unit has more than 50K on it, avoid it unless it's rebuilt. I'm more familiar with the ATI/Vortech units.

In my honest opinion, I feel that this thing will become much more expensive to do because the supporting mods that you will need to make the engine safe will just be too much.

Im going to call the owner tomorrow abd get pics and post them,Im not really worried about my hurting my engine,No joke there's at least 20 guys that i know that have mustangs that are supercharged with well over 100k miles,I guess these engines love boost,Im going to talk to my shop tomorrow,see what they say
I got a sound clip of the supercharger that im wanting to buy

Best advice right there.
Bent rods, damaged mains, god knows everything else that can go wrong will if you put too much into it.

thats what i was worried about to,but go to anymustang forum,I swear everone has there car boosted with no problems,pushing 400RWHP with the 2v 4.6 engine

The 4.6 2V engine responds well because the heads flow so badly they just won't suck air in when the piston goes down. The 3V heads flows a lot better. The 4V head flows as good as a LS1 head if not better.

I know a guy with an 03 Cobra and even his would put out blue smoke when he got on it. Come to find out it was caused by "blow by" and the oil going back through the PCV into the intake and into the cylinder. He got a filter for the PCV that seemed to cure it. I wonder how often he has to change or clean it. Well I guess it is had because he totaled it. I think it went to MPS too.

Let me also say that Ford was so concerned about putting a blower on the aluminum block 4.6 that all of the supercharged Cobras and trucks (5.4) got the iron block.

That guy I know that had an 03 Cobra had a dyno (dyno jet) slip with 411 hp on it. But that engine was made for a supercharger. It wasn't a converted GT.

I recently hung out with a Stang guys. One of the guys I know through the chick im dating, he has a 4.6l Stang with a Paxton S/C. He got his entire bottom end rebuilt and forged. He had it done and didnt know details but he is pushing 20+psi. He is looking at mid 600whp. Its impressive but its weak compared to the 03 cobras. Those are insane cars. 90% of those cars that were there where Twin Screw KB blowers, Stock everything pushing 550+hp with low to mid 10psi.

You would recommend you built at least the top end on your car. Heads/Cam/Rockers/Valves then start from there at the very least.

[Jeff_in_Atl]

The guy I know that HAD an 03 Cobrahad done a few mods to it. Like I said the HP was 411 at the rear wheels. The car is flat dangerous in the rain. The blower makes it produce a lot of low end torque and without traction control it can get away from the best driver. You really have to stay on top of it all the time. He was driving on I285 in a light rain, just barely (per him) pressed the gas and the rear tires let go. With the posi traction it kicked out to the right, then left then right then wall. BTW he had 275-40-17 Firestone wide ovals and they were almost new.

[FTA1995]

Same problems with TA TA in the rain.
New KDW's, 275 in the rear, if its wet, by-by back end. Too much torque.

when i worked at chevy, we had this cobra that came in on a trade, had about 60K on it, TOTAL piece of crap. Almost every single valve seal was leaking, the rings were worn to piss, and the thing had a nasty rod knock.
we though it was all because of the 10 psi blower the guy just threw on a stock motor.

Induction should come last, spend the money strengthening the motor and chassis/suspension/brakes first.

[DHolmes]

Well thanks guys,Im pretty sure im going to pass on the blower,I think i need to work on my suspension first anyways,I can barely get traction wright now with my 390 gears,so with a blower it may prove impossible,And it seems like its going to cost to much money,I just found out im going to be a father
