Hi!
I havent posted much but I've been lurking for awhile. It's pretty rare to find a forum so clean and informational - props to all of you. I spend way too much time in the archives.
My 68 mustang has a 200/3 speed combo that is on it's last leg, so instead of springing for the blasphemous 302 here's my plan. Please, tell me where I'm wrong.
Engine: 250 or big bell 200. Right now I just want the big bellhousing for a T5.
Transmission: T5 (I've already got the third pedal, and my wife is good with a clutch). The three speed just ain't tough enough.
Turbo: T4/S3-T4/O .58 unit. I want close to instant spool, and I stole this combo from Howards post: http://fordsix.com/forum/viewtopic.php?t=28140 . The numbers on this turbo seem similar to a Buick GN T3 so I may look for one of those as an alternative.
Carb:Holley 350 cfm. From what I've read a simple blow through setup will work fine with proper tuning (thanks Does10's).
Head: Hopefully the new aluminum one if I can afford it - what is the final cost anyway, with intake and studs and all? $1800?
Bottom end: All stock. I'm not an expert, but from what I've read, turbo power is not as hard on bottom ends as NA power. Linc 200's post gives me confidence.
Exhaust: Stock manifold with J pipe.
Cam: Stock (or very mild)
PSI: Maybe a max of 10 psi? I realize with the higher flow of this setup, 10 psi will relatively be alot of boost. I want to run on pump gas. Help me here as I am new to this, and I haven't read any turbo numbers with the new aluminum head.
Intercooler: Yes - simple air to air.
MPG: 22 on the hwy.
Rear: I'm running 8" with 3.50's and will probably leave it that way.
And here's what I'm thinking: I'll have $3,500 into this motor, and it'll be putting out as much or more torque than a 302 could with the same amount invested (maybe 350 - 400 ft.lbs, if I've done the math right). It will be unbeatable in real life racing - the 150 feet between the intersections of 5th and 6th. And with a stock cam, my wife can drive it to work without a problem (besides maybe a speeding ticket).
Show me the holes in my planning. I'm not a newbie with engines, but I am with turbos.
