Turbo 2 engine swap question
FYI I'm new to rotaries so please excuse my ignorance. So, my engine blew up. I have an 89 GXL that I now want to swap a t2 engine into. I want to know; can I use all the NA accessories on the t2 engine? I was looking and I want to get the t2 shortblock and then just buy a turbo upgrade + intercooler upgrade for it since I was never planning on using the stock turbo and intercooler anyways. The only other thing I can think of that I would need is the turbo 2 ecu. Would this work?

- Turbo intakes, throttle body, and throttle cable. A shortblock will not include these. BAC valve too. - Turbo injectors, fuel rails, etc. For S5 turbos (keeping the swap in series is a good idea) you will also need the little boost control solenoid valve that mounts to the UIM. - Turbo AFM, Turbo pressure sensor. - Modify harness (I don't have the exact details, but they're out there if you search). - Turbo II clutch, starter, slave cylinder, and transmission. The NA unit is known to break when behind a TII engine. - Either a modified TII driveshaft to mate the TII transmission to the NA rear-end, or a stock TII driveshaft and complete TII rear-end. Differential and axles must match, so both need to be TII. You also seem to want to run the stock EFI system but with an aftermarket turbocharger. This is not a good idea. The stock ECU has very little in the ways of engine protection, and no learning functions built-in. Putting an aftermarket turbo on an otherwise stock car is a recipe for a blown engine. Your good options are to run the stock TII turbo in which case you are better off just getting the longblock in the first-place, or to run a standalone EFI system. This will let you tune in the aftermarket turbo and set up proper engine protections, and allow you to ditch the stock sensors and harness entirely. There are other methods of tuning on the stock ECU. You could find a used Rtek ECU, or add fuel where necessary with an FCD and an S-AFC. Neither of these is an ideal choice, but there are people out there using them with no ill-effects. Realistically they are only a good choice for mildly modified cars. |
Thank you so much! So how much would it cost to do the complete t2 swap in the easiest and cheapest way? Money is the biggest problem, and I don't want to spend a lot of money just to keep a very slow engine

There is no such thing as a cheap TII swap anymore. These parts are harder to find than they used to be, and more expensive. How much it costs is nearly impossible to answer. A full TII swap recently fell into my lap for a great price and I'm still in the preparation stage, getting all my ducks in a row to minimize the downtime of the car. Last time I was offered a full S5 TII driveline (prior to the one I got recently for a lot less) it was $4500. That's engine, transmission, driveshaft, diff, axles. Engine in used condition. Now I'm in Canada so prices are different, you will have to get prices near you. Engine importers may have them cheaper since they were more plentiful in Japan, but the engines are always suspect. I don't know what the stock EFI parts in good condition, but if you're going standalone then MS3X + harness can be done for around $800 USD if it's a basic installation (using stock injectors, stock coils, reusing good connectors from factory harness, etc). Then you still need a fuel pump which I forgot to mention earlier, and either a TII hood for the stock intercooler OR an aftermarket intercooler. Like I said, there is no such thing as a cheap turbo swap. |
Ok, thank you!
