SPG Posted October 23, 2016 Share Posted October 23, 2016 Hi Guys, I am currently piecing together the last few parts for my most recent Supra project. Now I have the opinion of either a V160 or V161 to use, which will be coupled with either a B03b or Large Case U.K. Diff (Auto). I have a A02b as back up also should the option be presented. This project won't be pushing for power, and will most likely see BPU at a push. I'll be using this car for the odd spirited drive around the countryside not really fussed about the motorway. I'm just trying to see which combo you guys have and a little help with selecting the right combo for my project. Base car is an Aerotop with TT.

np89 Posted October 23, 2016 Share Posted October 23, 2016 I have a V160 coupled with a B04D (UK Auto), I find it provides great acceleration and it holds a nice balance on a back road for swinging on and off boost but on the cruise say at 70 odd mph it revs about 3000rpm in 5th which to me is a little high but dropping into 6th will drop to about 2500rpm Quote Link to comment Share on other sites More sharing options...
Andrew K Posted October 23, 2016 Share Posted October 23, 2016 For my build I went with a V161 and coupled that with the Large casing LSD from a 6speed manual (B03B) as I wanted good low down acceleration and not run out at top end or when in higher gears. I think this is a perfect setup for every day use or just the odd spirited drive around the country side. Quote Link to comment Share on other sites More sharing options...

In my RSP I have this set-up from the factory, unusual I realise, but I'm really pleased with the way my car drives with this set-up also. Andrew how do you find motorway speeds with your V161/B03B? I'm sure my car sits around the 2400rpm mark in 6th, from memory. Quote Link to comment Share on other sites More sharing options...

Punching the values into that gear ratio calculator thats on the forum it looks like the values I see on my car are accurate and then using the V161, at 72mph you would see 3000rpm in 6th Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted October 23, 2016 Share Posted October 23, 2016 My car has a V160 with large case TRD diff with an unusual diff ratio of 3:538. This was done deliberately by the previous owner by changing the crown and pinion in the diff. Apparently it sits between the auto and manual diff ratio and gives quicker lower gear response, but does sacrifice some higher end power. This is on a single turbo though.

It's pretty good to be honest, I drove it all the way to the Nurburgring last weekend and the majority of the journey was on the (E40) motorway, cruising along at around 80mph off boost I remember looking down at my rev counter and being surprised at how low the rev's were but I can't remember exactly though now (brains like a sieve) but think it was about 2500 / 3000rpm.

Mika Posted October 24, 2016 Share Posted October 24, 2016 I have the Getrag V161 with the B04D (3.538:1) diff and I think it is a really nice combo in use. My car is BPU+++. Quote Link to comment Share on other sites More sharing options...

I also have the same combo and I find it to be a great setup for road and the track. Quote Link to comment Share on other sites More sharing options...
SPG Posted October 25, 2016 Author Share Posted October 25, 2016 Thank you all for your input, I guess I'm going V161 with B04D . Quote Link to comment Share on other sites More sharing options...
