I am planning on installing a turbo 99 engine into my 97 NA. The PO is suggesting that I use a MSII PNP built for 97 instead of one for 99. I am new to turbo and was wondering which way to go and why.

Thanks.

 

I'm pretty certain a 97 motor uses a cam position sensor for timing, while the 99 motor uses a crank trigger.

 

has a different alternator too. If you put a 99 motor in your car just make sure it's using all your 97 sesnors and harness stuff. I think you need to swap the fpr too as 99 is returnless. Yes you want 97 for simplicity sake.

 

this dude is right as well. You should swap over your 97 motor bits and pieces to the 99.

 

I would use the 99 crank trigger anyday over the crappy cas.
You shouldn't buy a pnp. Have Brain build you a ms3 for you car, he can always modify it later for any year car you want.
If you buy a pnp, your stuck for that specific year (and probably similar price).

 

If I go with a 99-00 MS3, is there a lot of work involved in getting my 97 instrument and gauges to work properly? Electrical is my weakest link..
Also is AEM a better choice in my case?

 

No, brain can set it up fully plug and play. PM him and forget about aem's, mspnp's or pnp's with non-standard firmware. Do it properly first time and get a ms3x. Newest firmware even has 99 alternator control.
