Hey guys,
So I need to rebuild my trans since my syncros for 3rd gear are bad. I was thinking of upgrading to 6 speed but it cost way too much to do that. Next option was the JDM Type-R setup which seems popular for most of the guys around here. But I was not too sure if Type-R fanboyism have made views biased so I decided to do some calculations to get down to the truth. So I created a spreadsheet that has the differences between US gear set, JDM gearset, Type-R gear set, and US with Type-R final drive. (I did do a search and I know there is a thread out there with plots but I was having a hard time finding it. If someone has favorited that thread please post it. I would like to look at that data too.) ( Just realized I screwed up one of the forumulas so I redid the spreadsheet and it's now correct.
Relative to the stock US 5 speed:
Looking at the new data it seems that the US gearset with the Type-R final drive is a definite improvement over the stock setup. The type-R setup is best up to 130 mph. The JDM gearset seems like the middleman that doesn't hurt top speed but still gives you better accerleation throughout.
What do you guys think?
*Data from science of speed gear ratio charts.
**Table of times from 0 to X mph
