yes how possible is it to drop a turbo 2.3 engine into a 91 gt? whats needed and will the stock AOD bolt up to it?

The AOD will not bolt up. You will need an A4LD if you want to stick with an auto. You can use the same rear but you will need a different driveshaft(I believe). turbo 2.3, harness(depends on mass air or map), reroute fuel lines. I'm sure I am missing something. Why would do that? That would be a lot of work with nothing to show for it.

i'd be better of buying an svo then?
the reason is to do something different

motorman524

yeah, just buy an SVO. They aren't cheap though.
How would that be different? there are tons turboed 4's running around.

I guess you could buy a tbird turbo coupe and swap everything as well.

i meant different as in i have never heard of someone going from a perfectly good heads/cam 302 to a turbo 2.3

the stock a4ld won't hold up well to it. Some people have ran a c4 using an older pinto bellhousing. I ran a t5 for mine because it holds up to quite a bit if treated right. They use a vam instead of a maf. Not such a good thing, but it got the job done. Some people have switched over to using a maf. I personally went the standalone route & ditched the air meter all together for less inlet restrictions so mine is setup as speed density. You would need the pistons, computer, engine harness, & air meter from a 2.3t car. The rest of the parts can be had from a n/a 2.3, you'll need the fuel lines too (they come out on the drivers side instead of passenger like the v8). The weak link to the n/a engines is the pistons. Everything else will hold up to around 400hp, some have pushed it above (there's actually a guy on this forum running around 540whp with the stock bottom end). The stock n/a pistons will give out around 5psi. The 2.3t itself is pretty well bulletproof.

The big problem with the 4 cylinder is the head. A good aftermarket aluminum one will set you back $2000 which is pretty crazy. Boport is a pretty recognized company for porting the stockers (aswell as aftermarket ones) getting them in the 400+ hp range

I had the chance to buy an svo for $1000. The reason I turned it down is because of their value, I knew I was going to end up modifying the car, so I bought a notchback & put a 2.3t in it. After I got a 351w I ended up swapping the 2.3 into my ranger for a quick work truck. Personally I'd just buy a junk mustang with a blown engine or something for it. The low end power is nice to play around with sometimes.

Turbo the 5.0 instead.
