I have an 88 hilux dlx longbed, four wheel drive, automatic truck, plus it is a 22-re engine. Are there any modifications I can do to this? also is it possible to change it from an automatic to a five speed transmission?

 

there are mods, and it is possible do some searching and you will find out what you are looking for.. as for the tranny im not sure what all needs to be done but people do, do it.

 

You will need to get the clutch pedal and associated parts with that installed, and then you will need to get a flywheel for the engine, and then install the manual trans!
