Hello there!
I have a JDM forester s/tb '00 year with standard engine and turbo.
It suposed has 240 hp with japanese specs. It boost 12 psi stock
Im using my forester for offroad sand dune climbing, with 275 60 15 tyres.
Because i use the ride for almost offroad, i need a lower ratio gear setup, so there are two options.
Easy Way
Sell my ride and buy a JDM ´00 S/20 aspirated dual range Forester (problem solved, but no turbo=no fun in sand)
Swap my 5MT Gearbox for a 5MT aspirated forester with dual range (1: 1.4xx) reduction ratio. (best of both worlds)
I know that the extra power can destroy the gearbox, but im planing to put a boost control and reduce the turbo it to around 2-4 psi when a low ratio gear is selected, and also take care with the gas pedal.
So, now there is the questions i have.
1. Is this mod be practical? can the trany resist the engine taking with care?
2. Apart from the gearbox, what other parts i need to finish the swap?
FYI it seems that the 5MT turbo has 4.44 final gear, and the NA 4.11
Any ideas?
My ride with 275 60 15
Thanks for the help
