ur budget will also contribute alot to the project as well
the engines that u have stated veray greatly in price
1uz $1700
rb20 $1000
rb25 $2000
1jz $2000
2jz $4000
the toyota prices are fairly accurate as i was recently looking for a conversion for ly ls400 and these are the prices i got.
ill be honest with u, u wont be able to do much for less than around 10 grand. half of the motors need some serious custom shit to make them fit in + the wiring will be a nightmare and add huge costs to it also.
if i were u i would put an s15 motor and s14 gearbox and it would hammer hard as
but if u have the funds then definatelty go the 1uz. that would be sick
a v8 silvia lol
