If I was in your position, I would definately go with a small block chevy and auto transmission. 350 and 350. For the cost of rebuilding or buying rebuilt you could upgrade and be much happier.
Update, clutch still slowly lost pedal so I went ahead and replaced the external slave cylinder. A lot about using a socket and punch to drive out old pin. If you only have two hands like me a 1/8 drill bit is a good friend. Pump bled the air a few times and then topped it off again the next...
It was fine yesterday, this morning clutch pedal goes to the floor. Fluid is full, I don't know anything about slave cylinders. '95 2.5 ax-5. Any advice?
No electronics changes. It's really a simple swap if you know the pitfalls to look out for. The injectors are 19lb (yellow) ford 4.6l. They just plug in. The main benefit is they have 4 holes in the end where the stock ones only have one hole. You get a much better atomization of the fuel mix...
It made a big difference. I swapped the tb at the same time, so I don't know how good it is by itself. I bought the injectors used off of e-bay for $50 and the tb for $30. Popping out the reducer in the front of the airbox made the single biggest differnce so far.
Found it ! The plungers on the iacs are different. 2.5 is tapered and 4.0 is flat. Changed the iac housing on the side of the iac and solved the problem. Would have been much easier to do BEFORE tb was on the motor.
Yeah swapped those too, no map on mine. Saw a suggestio to swap iac housing also, going to give that a try next. It's just the first 20-30 secs of each stert up, everything else is fine.
I put in the 19lb (yellow) injectors and a 4.0 TB on Thurs. and since doing it the idle shoots to 2000 rpms at start up for about 20-30 secs. I thought the computer just needed to adjust itself but it's not getting better. I did change out the 2 sensors and triple checked all nearby vacuum...
