Problem:
what turbo to chose?:
- GT2860RS 0.86 A/R
- GT2871R 0.86 A/R
- other
all the parts mentioned above are already on the car or they are already ordered and are on the way, my bigges problem remains the turbo, i do not know what turbo to chose so i can have the best eficienci tu run at the top limit of the gearbox
GT28RS stated for max 360HP i think this amount of power will be of for an upper limit of the gearbox (before destruction)
GT2871R stated for 400HP from what i have understood at 400HP only with a lot of luck yor gearbox will not "self" destruct.
having this in mind maybe you will help me answer few qestions:
- can anything be done for cheap to incrase the strenght on the gearbox?
- can GT2860RS be pushed over 360HP (stock T25 is stated for 210HP but if pushed to the limits 240HP can be sqezed out of the CA18DET using stock turbo)
- car will be used for drag racing and the gearbox seams to become a week spot in the "race" for big HP any advice, or triks that i may do to the gearbox for cheap?
my target for now is 301WHP (during hot days in summer)
to conclude:
- anything that can be done with the gearbox (for cheap to go to 350-400WHP or more)
- GT28RS will push the stock gearbox to the limits or the stock gearbox can handle the abuse of a GT2871R?
