I am in the market to get an mr2 right now and I test drove a 91 turbo. I had a few questions I was hoping you might be able to help me out with. First of all, the guy wants 5800 for it. The paint is starting to fade out in a few places but is pretty solid overall. There was quite a bit of oily greasy buildup around the valve cover and that had me a bit concerned but perhaps this is just a natural fact and it may only need a new valve cover gasket. I still don't know how to discern the magical harmless gunk that builds up in the coolant reservoir between that and oil. The little plastic filter thing on the end of the hose going into the reservoir had some brown stuff which looked like it was once a brown liquid that dried up on the plastic deal.
The driver's side seat is missing it's leather, lol. The owner said it got all hard and cracked so he just pulled it out. I don't know how much it would cost to get a new driver's side seat, although it really wasn't all that bad sitting in it without.
But here's the big thing I'm still trying to understand. When I started it up and cruised the streets, not punching it yet, the turbo gauge needle was all the way rock bottom. It was right next to a minus sign. I was under the impression that it should actually sit at the mark above that which looks like a zero point. The gauge would only seem to show boost sporadically. There were a few times I punched it, wrapped it up to 5-6k and yet the gauge would only show activity a little bit. Then there were times I only climbed up to 4 and the gauge would go up quite a bit.
Now, I don't know what the stock psi on the turbo is, but I heard no turbo whistle as I pulled through the rpms. I also didnt notice that it pulled in a turbo-ish kind of way. But it did pull strong. It pulled nice and hard like an na would be expected, there just didnt seem to be that kick towards the end of each gear like I thought it should. Would this engine still pull at all though if the turbo was faulty? Or would the lower compression of the engine make for a sluggish ride without the boost?
Basically I'm just trying to figure out where the problem was with this ride. Is the gauge typically a faulty gauge as it is with some turboed cars or was there something wrong with this baby? The car had 144k on it, is it time for an overhaul, rebuilding the engine and turbo on this thing?
I really loved the car otherwise and it was a sexy little thing so I would love to get it, but I want to either stay away from it because it's falling apart, or I want to go in and bargain like hell because of some of these things I noticed if they're really not a big deal.
any advice and direction would be much appreciated...
