Hello forum folks, new guy here and just wanted to put to bed any questions regarding how tough an r150f can be. My vehicle is a 92 4runner, swapped a 1jzgte single turbo. Haltech Elite 2000, ID 1000cc, Borg Warner SXE 62mm, Aeormotive fuel system, currently running e100, Dyno tested @ 540hp 560tq @17psi. (on the wastegate) Trans. is a fresh r150f, clutch is a Six States built 6puck unit, I used Marlin upgrades such as hardened thrust washers and bearing retainers, new bearings and syncros. Rear diff. is Toyota 8 with Yukon 4.11 micro polished gears and a converted 29 spline pinion. Also has the Yukon LSD. I have heard this and that about the r150 so I wanted to find out for myself before i swap to the th400. I recently drove the truck to Vegas, (pulling a trailer from Utah) swapped the tires to Nitto 28/10.50/15 drag radials and gave it the beans.
Haltech Launch Control set at 4200rpm, dropped the clutch and away i go. Trans. felt solid, truck went down the track and ran a 12.40 @ 114mph. So these are fairly stout transmissions. My next mission is to add more power and raise the Launch control to 4800. (I am actually trying to break the trans.) I want to know how tough they really are. Currently adding another pump so i can raise the boost without suffering fuel pressure loss.(ethanol requires alot of volume.) Will dyno tune again and give it another go. Target hp is 700 and 700tq.
Will keep you posted. best regards.
