Got some questions that have been bugging me.

I was planning to go all out with my Mustang and spend $15K to make it an 8 second street car (race block, Turbo, PA C4, etc.) but I decided I should hold off dumping that much money into a car for now.

Instead, i'm planning on doing a stock block build. Plan is to get a Vortech V1 S-trim and push 400 RWHP safely. And also keep it a 5 speed. My T-5 felt bad at the end of last season, so with the added power im sure its gonna shit. So I plan on getting a Tremec TKO.

With the Tremec, what else do I need besides the transmission to make it work? I know bellhousing, is the clutch, and shifter interchangeable?

Also I noticed last year when I did a pre race burnout, it did a 1 wheel peel, or atleast appeared that way. That means my tracklock need's re-doing right? Is it worth rebuilding, or should I just go with an aftermarket replacement for the 400rwhp level? What about axles, will Moser 31 or 33 splines handle the anticipated power, or should I be thinking about getting a whole new rear axle setup?

And to complicate the rear axle equation more, the previous owner did a rear disc conversion. I think he said the axle was out of a TurboCoupe Thunderbird or something.

And finally the engine. Its a stock 302 shortblock, rebuilt about 15,000 miles ago, with all the basic bolt on's. I already have a 255lph fuel pump, fuel regulator, boost gauge, and a few other things, as this car had some type of centri blower on it before. Im wondering about tuning it. We have a really really good mustang tuner in the city that does dyno tunes, but do I need to buy a tuner like a Diablosport unit or something for him to work on it?

Also, I had some vacum problems last year, it was sucking oil into the intake. I replaced the steel filter thing and the PCV Valve and it seems to be fine now. But should I take any more precautions once i'm boosted? Does the kit come with anything to help with that?

Heres the engine mods that I can think of off the top of my head.

-Ported stock E7's
-Ford E-cam
-Edelbrock upper and lower intake
-BBK CAI
-Steeda underdrive pulleys
-Summit calibrated MAF
-Shorty headers and full 2.5" exhaust
-3:73's
-smog and A/C delete
-BBK Throttle body

Thats the main stuff that I can remember

Alright, thanks in advance.

forget the E7's. get the eaton LSD with some 31 spline axles

[jack90gt]

Def ditch the e-7's...You will never get the full potential out of a blower with them...

if you can build an 8 second street car for 15,000, build 2 and I'll buy the second one.

lol

for 400 hp, you don't need anything more than a rear rebuild

There is a whole list of modifcations that should be done to the PCV system for boost. I would recommend getting a breather in place of the oil fill cap, removing the throttle body to oil filler neck hose and pluging the ends, and getting a oil air separator for the PCV hose.

I believe thats a vacuum leak

Same as always. Where do you think the filler neck hole tube goes? To the air box side of the throttle body.

It is a vacuum leak, but the PCV draws such little fresh air into the crank case that it is not a problem.

[93mustank]

But with the tube in place its still vacuum drawn....with a filter in place nothing is pulling air out of the motor...... instead it pulls the air in....

they did it for 10,000 on highschool drags!!

lol. My cost estimate was probably kind of conservative. I just did a quick add up of parts. That was with no labor, and not counting vehicle cost. Also counting on getting $3500 for my current engine back.

Anyways, everyone is saying ditch the E7's, I know that already lol. I wasn't the one that spent time porting them, I got it like that. But the question is would they be able to support 400RWHP, or is it going to be necessary to get some other heads? Remember, Im not looking to exceed the 400 mark. If I was I would be going turbo.

Edit: Would this be good enough for my rear axle?

Anyone else got an opinion on some of the other questions?

[89LX347]

for the price of that summit kit you could find a used rear end and you dnt have to pay for labor, heck i bet you could pick one up for 700-800.

didn't you make a separator a while back ryan? or at least post something about it....i need one

[95StangMX]

screw it build 3, I am 10 grand in already, and thats without labor, and without suspension, just a well built 347 and aode worked over with a stall.....The e7's will hold you back

Heck if you were looking at spending that amount on the rearend I would invest the P2000FM kit from Strange and be done with it. But if its a DD the spool would probibly get old. Or you could get strange/moser axles and an Auburn/Detroit locker style and you would be good. Just my .02

Im lookin to spend minimum lol. Well not the cheapest, I want good stuff, but you know what I mean. No more than I have to.

Its not a daily driver, its a weekend, and the odd evening driver btw.

And for the 15K car thing lol, think about it, $9000 or so 8.5 certified roller.

Example: Race Ads | For Sale: 1990 Mustang 10.5 Stock Suspension Roller

then you got 6'gs for engine setup, $3500 or so indestructable shortblock used, throw together a budget top end, and boost the shit out of it lol. If you were determined enough and waited for deals, did all the work yourself or with friends, you could do it.

Anyways, what heads do you recomend? Gt40's seem good, but dont you need new headers and an intake then? I dont wanna go through the trouble. I dont think I need AFR's to get to 400 wheel with a blower. How much power would an S-trim at 8-10PSI with the E7's get me?

[jack90gt]

Wow what is up with that hood?????

hmm indestructible bottom end and budget top end, not what you wanna do.
2500 for the rest baha, your foolin yourself. . i recommend theturboforums.com if you are looking for a boosted application. i recommend a good set of trick flow or AFR heads. estimations of HP are just that....an estimation. what cam are you gonna have in it, compression, tranny, gears, intake. too many variables to just throw that question out there

Bottom end I saw a few days ago... A4 Shortblock, Billet crank *smoking deal*

And top end can be gathered slowly if you wait for used deals localy.

Enough about the imaginary 8 second car though lol.

Its gonna have E-cam, stock compression, Tremec TKO, 3:73's, Edelbrock intake as of now. It has all that besides the tranny right now. T-5 right now.
