Ive heard so many different things about parts you can use together parts you cant use together and all of the between.

Since i blew up my tranny and clutch and have been wanting to convert my car to a turbo, i was planning on buying the motor and tranny from a turbo ii and using the rest of the stock na drivetrain for the time being.

Ok here comes the questions:

ive heard both ways that you can and cant use the stock n/a driveshaft with the turbo ii tranny, what the deal with this?

If i get the engine harness ecu and knock box, is it a plug and play deal or is there still more harness modifications needed to be done?

Is there a way to modify the main car harness of the n/a to accept the gauge cluster form the turbo ii?

And if you do have to change the whole drivetrain is there a way to keep the stock 4 lug hubs or do you need to go 5 lug. Reason being i have a brand new set of 4 lug wheels and dont want to have to get another set to acomadate the 5 lug pattern.

Please dont say to search, the searching is what got me so confused

1. The NA driveshaft will not mate to the TII tranny. The output shaft on the TII tranny is larger than the NA one. You can either get a TII driveshaft and have a driveshaft shop make you new shaft out of the TII shaft and a NA shaft or you can get an Auto driveshaft and have it shortened.

2. The harness should be mostly plug and play assuming you use the same series Turbo harness that your car is now. ie. S4 to S4 , S5 to S5

3. You are better off keeping the NA gauge cluster. All you would gain by swaping it would be a shitty boost gauge and a 160mph speedo. You also lose a gauge (voltometer I believe).

4. You can keep the 4 lug suspension.

If you put a turbo engine and transmission in a n/a car, you have to get a hybrid driveshaft. One can purchase one from Mazdatrix if you call them on the phone, or get one made by a local driveshaft shop. Some say a auto driveshaft will work. But it's not the right length, so don't do that. It barely reaches.

I've no idea what series car you have. I've done a series four n/a to turbo using the n/a harness with some wiring changes. It's a series four turbo and transmission using a n/a rear end.

Since you mention a knock box, I assume you have a series four. The series five have the knock box inside the ECU. Note that a car will run peachy keen without a knock box. It's probably better to have a knock box, but the car will run just fine without one.

On a series four the only change is to the Emissions Harness. No other harness. The Emission harness is the one that runs all over the engine and runs along the right side of the engine bay. If you get the turbo harness and box....yes, it's plug and play.

You also need a turbo transmissions mount. The n/a trasmission mount won't werk at all.

You should also buy a turbo ECU and BOOST/PRESSURE SENSOR (MANDANDTORY IMHO).

You can run with a n/a afm, but be sure to get the turbo inlet/outlet duct off the turbo engine. And get the downpipe. The exaust is obviously different.

You don't want the turbo gauge cluster. Buy a aftermarket boost gauge. The stock is suspect. I could make the n/a harness work on a turbo gauge cluster. I don't know about you though. Again, there is nothing to be gained by having a turbo gauge cluster EXCEPT the loss of a volt gauge, which is more important than a suspect boost gauge.

i do have an s4, illhave to get a hybird driveshaft then, thats no problem. One last question, would i do better getting a jspec motor or finding a non jspec?

Thats up to u. Either way u might wanna think about rebuilding the motor when u get it. Just to be safe and for reliability.
