Hey Guys , just looking for opinion on which box to go for in my toy . As some may know by now Im building a TG Gemini with an RB30 in it . I've gotten a few bits & pieces together to make it a real weapon , CPC Plenum , Billet fuel rail , T3/4 turbo off Lebrocon from these forums , 9 inch , 411s , 28 spline minispool & plan on using a 26 x 8.5 slick . Thinking it should make about 350 hp at the wheels , haven't decided what box yet . Was thinking to go a c4 , but with the 411s and relatively small tyre , im concerned that it will run out of legs at the track . Just want some input on what box to use , c4, trimatic, 3 or 4 speed jatco ????? Thanks Regards George

vlt jatco would probley be strong enough but dont know about the ratios.

Trimatic is your best bet for that setup, with a 3200 stall, full manual and shiftkit

Keas Jatco. it will laugh at that much power and ask for more.

go 3 speed trimatic

all three speeds use 1:1 top so all depends on diff gears if you are worried about the top end speed

whats gives more top end, wat kind of gears ?
