Im Curious if GTE or Freelance or anyone would know which transmission has better 1/4 miles gearing, i think the v160 is faster gears correct? Also i read on some supra forums that the v161 is out of a JDM supra because they were limited on the HP they can run so they ran longer gears and got more speed.....? Ayways im doing a 6spd swap, just curious which tranny is better, shooting for 600+ hp all custom gte block vvti head. thankyou

I'm sure an internet search would net you the gear ratios on both transmissions. Then, if you know what kind of power you will be putting down, figure out which will suit your needs better. An important thing to think about- what rear end will you be using?

Here- I found this in about 2 1/2 minutes of searching

http://mkiv.supras.org.nz/specs.htm

v160
1st- 3.827:1
2nd- 2.360:1
3rd- 1.685:1
4th- 1.312:1
5th- 1.000:1
6th- 0.793:1
Rv- 3.280:1

Final- 3.266:1

v161
1st- 3.724:1
2nd- 2.246:1
3rd- 1.541:1
4th- 1.205:1
5th- 1.000:1
6th- 0.818:1
Rv- 3.192:1

Final- 3.769:1


So, looks like the v161's final drive more closely matches our stock rear end. It looks to be a good selection, because the supra rear end and half shafts make up a good chunk of the cost of a swap.

Yes, or your gearing will be way too short. Especially w/ 600+hp!!!

haha, you'd be shifting every 1.5 seconds in the 1/4 mile, and with 25.4" tires (265/35R18), you would redline the car at 6500 in 6th at 121mph!!!

Then again, you could always raise your redline to 8k, but the gearing will still be too short to be comfortable.

Not to mention. you will be spinning your tires all over the place.

It has longer gears than the stock w55. Mine is from a '95 N/A Supra.

Time will tell if it holds up, but many N/A-T supra guys are running around on them with 500rwhp and doing ok. It's no v-160, though. That thing is BULLETPROOF.

Final of the TT rear, as stated above, is 3.266:1. You will have to make your own decision on what to run- people kinda just mix/match the rear end with their desired shift points to stay in their powerband, and their choice of transmission. Pick a tranny first, then pick a rear end.

Google searches will yield some good gearing calculators that will allow you to calculate your speed in each gear at different rpms based on gear ratios, rear end, tire diameter, etc.

DO you think i should be hesitant on buying a used v160? i mean i know getrag can do some crazy stuff, and they hold up bigtime. but i mean i love to powershift, when i leave the line, that petal doesn't leave the floor and im wondering how strong that v160 really is, i mean what if the person that drove it in the supra beat on it, is this a problem or do i have to pop for a new trans?
