In reality it should pick up 30 ponies. TRANNY? AT or 5 SPEEDER. rear axle ratio?? The whole thing stems on the entire package. Cam change is always good for ponies on a 2.3. That cam has good numbers for a nice torque curve. It should be real torquey on a broad RPM band. Is that cam for your 2.3??? It looks like a small block ford cam??
1 of those cams is for a 2.3 but the specs are so close. I typed in 2.3l ford cam and all I could find was the small block. The other is a stage 2 for a 2.3l. It's automatic with the original rear end, 8.7. I'm going to put a 8.8 in with hopefully a 4:10 gear change. And yes, this is for my donkey. Do I have to change the pistons or anything like that? Should I use a 3:73 or do the 4:10?
RWA 1403 looks real good on a stock motor and a drop in cam. The lunatti looks real good and is a little milder than the 1403 I have used many a lunatti cams in the past they are real good BUD/p>
Should I go with 3:73 or 4:10 with that setup? And do you happen to know what vehicles I can pull a 8.8 rear end from that'll bolt right up in my 2.3l? Even if it sticks out a hair further.
I would use a 3.73. You can get an 8.8 out of a GT mustang. Your 7.5 is ok with an auto up to app 260 ponies. The 7.5 is a fairly strong final drive.
It's very rare that you'll find a GT mustang in the yards here. They are all 4 and 6 cyl. So that's why I was wondering what else I can snag one from. And can I fit a 3:73 gears in my 7.5?
Hi chandler The factory 4 uses a 3.73 with AT. Thats good to know. Thanks. The 5 speeder uses a 3.5. So they have the same ratio as the AT turbo coupe?? Thanks good to know. I thought they had a 3.5 in the AT?? We have actually had good luck with the 7.5 in the 4 cylinder AUTOS. Whats your experience with them chandler. I know if you go easy on the 5 speed jobs they last. But dumping the clutch with a 7.5 i am not shure how strong. I figure app 250 HP is max for a 7.5 auto what do you think. Thanks chandler
The 5 speed 4 cyl cars left the plant with 3.45 (which would look a lot like 3.5 if you used the wheel revolutions vs. driveshaft revolutions.
The 7.5 is a relatively stout setup. Its like the 8.8's little brother. It just doesn't like "instant on" brute torque. Like the 4cyl. T5, you can put the power to it, but you can't pile it on all at once (unless you have a weird desire to replace rear diff parts on a frequent basis). I can see why you had good luck with it behind slushboxes. The right converter will deliver the goods without the shock associated with sidestepping a clutch pedal. Add a trans brake and all bets are off.
I wouldn't be in a big hurry to replace my 7.5 with an 8.8 if my car was still relatively stock.
Tom, I know that the Aerostar, Ranger, Bronco II line could be optioned with a 7.5 trac-lok. Have you ever seen a 31-spline 7.5 center section? I think for a good street turbo car a 7.5 31-spline trac-lok would be the ticket if such a creature existed.
