Considering buying VR4. Questions.

I was looking at this car. It seems to be a little over priced, but it's just an asking price of $8,900 http://www.wheeldeals.com/details.ph...ealerid=150477

I have a 96gsx (sig) that has been fun, but I'm thinking its about time to move on to something else. I don't plan on getting rid of my DSM, I just don't feel like working on it any more. I have a few questions about these things.. I spent a good couple hours on your FAQ and website links. I found out most of the information I was looking for, but just had a few brush up questions I has hoping someone could answer for me.

The MAF seem to be identical to the 2g sensor, which is cool because I have a couple extra MAF's, FIPK's and Aircharger filters in the garage. But my main question is; since they have the same MAF, has anyone used, or heard of someone using the ever so popular GM MAFT tuning device for the 2g DSM's?

Is doesn't look possible, but has anyone taken a DSM TDO5h 14b, 16g exhaust housing off, modified the the stock TD04-09B exhaust housing and successfully mated the two together to fit onto the stealth manifold?

I noticed the fuel cut section of the stelth316.com site. In the DSM fuel cut is initiated when 2.55g/rev airflow is reached. I understand fully decel fuel cut, and rev limiter, because I have DSMlink, but has anyone definitively discovered the actual g/rev fuel cut in vr4's?

Does anyone possess/willing to share the fuel enrichment and timing maps of the 1st gen stealth 316's? I'm interested in peak timing and fuel enrichment variables. 2g DSM's peak at +55% stoch above 4500rpm when 2.1g/rev is reached and peak of 16deg advance timing above the same airflow value. I'm just curious. Do different generations of 316's have different timing curves? Do any 1st gen 316's come with eprom ecu's that will allow from PROM chip burning, making it able to create my own timing, enrichment, 3-step rev limiter?

Are their any true weaknesses/disadvantages in owning aside from the 2bolt engine and different body lines? I know the 93 seems to have everything + OBDI. I might hold out for one if it's really worth the weight..

Thanks for reading, please comment.. Scott..
