Yes, The cars are exactly the same body wise.
No. The gs is the base eclipse spyder model.
according to my pressure gauge on a 99 gst at idle about 50 and 3200 about 75psi
one is a turbo, and one is not
A Spyder GS is a non turbo car. A GS-T on the other hand is a turbo car. Hope this helps
If it is a Gs Spyder then it is 141 HP.
the non turbo 420a makes 140hp and the 4g64 spyder engine makes 141.
I had the same problem with my Eclipse it was the spyder turbo i had put cheap gas in it. went to 93 octane had no problems.
Yes, you can, but there is a chance that you will need to change transmission and everything what is going inside the engine. The problem is that Mitsubishi engine parts from different engines are not compatible (it can be turbo Japanese engine, or non-turbo crysler engine and so on).
I very doubt it. If I am not mistaken GSX has all wheel drive system and turbo charged engine. Any of those make it incompatible with any other transmission.
For the right price you can put a turbo on just about anything. Unfortunately for you the cost to put a turbo on a non-turbo eclipse is probably more than going out and buying an eclipse with a turbo already on it.
There was a stock turbo option for the 93 eclipse. there was also a non-turbo (n/a) option.
If you have a digital cluster then you need a new cluster.
