4x4 upgrades on '80 GL


Recommended Posts

Before you get into upgrades you are going to need to swap out the engine and tranny for a dual-range tranny and side-starter engine to match (EA81 is a good choice). Without the low-range of the later '81+ dual range transmission you aren't going to turn large tires for beans and if you can't do that then you have no need of a lift.

 

Then you will want to yard out the carb and install a Weber, or do the SPFI conversion. Here's a link to my conversion write up:

which would supply more power? and more worth while to swop?

 

SPFI is more worth while. It has more power potential - it came off an engine with 16 more HP and will automatically handle upgrades beyond that due to it's computer controlled feedback system.

 

SPFI is also more desireable off-road as it naturally has no problems with severe angles. The Weber will starve for fuel if you get it on a really steep incline due to the float bowl not being level.
