LEEN Gearbox Conversion: LexusIS200 AZ6 to Toyota "A&qu

[oldeskewltoy]

Its kinda funny... and yet something I didn't recognize till just now*. This adapter should offer FAR more transmission options then a T50, or a W5x, or almost any other under $10,000 gearbox options. What do I mean....

Jesse - he wants the SXE10 version. He has done quite a bit of research and he likes the J160 (IS200/SXE10 option) the best. In chats with Jesse his thoughts are somewhat based on the J160's close ratios in 4th, 5th, and 6th gears. This allows an easier time reaching TOP speeds. Jesse can chime in to further explain...

Miura - he likes the S15 box because it fits his thoughts of low diff (4.5, 4.7 or even lower) and with the extreme 6th still be able to cruise the highway, or talk to someone while on the highway.

oldeskewltoy - I still like the Miata ratios the best. As I wrote in my original idea(back in 2006) for this transmission, to "fix" the problem Road & Track described about the AE86 back in Feb 1985....

Road&Track - Feb 1985 Wrote:The GT-S was a fraction slower**... ...there were times and places when the engines power couldn't be used... ...the jump from 2nd to 3rd is too wide and the jump from 4th to 5th isn't wide enough

** - commenting on a track day @ Willow Springs and comparing the GTS to the Mitsu Mirage Turbo -

For me, its obvious the Miata version is what I'm still hoping for. I do have a secondary motive too.... This will allow this to be even bigger if it allows a Miata owner Toyota power :eek: :eek: :eek:

* - Add in all the ratios that had been available... that includes TRD, and NISMO, as well as HKS made a set or two... I believe in gold(j/k) because they sell, or sold for about $10,000 :eek: :eek:

S15 6 spd 3.626 2.200 1.541 1.213 1.000 0.767
NISMO 2.907 1.989 1.537 1.218 1.000 0.862
RX8 6 spd 3.760 2.269 1.645 1.187 1.000 0.843
Miata 6-spd 99- 3.760 2.269 1.645 1.257 1.000 0.843
SXE10 6 sp 3.874 2.175 1.484 1.223 1.000 0.869
TRD(33030-SE100) 3.106 2.175 1.585 1.223 1.000 0.869


I've already included a link, why not play with the gear ratios available and see which se up is best for you

ALL of us now have an option. As long as the LEEN adapter fits we all can have a soultion :thumbsup: :thumbsup:
