Technical Stilo GT - 5spd manual to 6spd manual gearbox swap from Lancia Thesis?

[Ralf S.]

Have a look at this site:

http://wallaceracing.com/calc-gear-tire-rpm-mph.php

I've tried it out. Based on a 215/45x17 tyre, if your 2.4 does 3500rpm at 80mph, then a JTD ratios (if the actual gears fit, or if you just fabricated new gears with the same ratio) would give you 2720rpm.

If your 2.4 does more than 3500rpm at 80mph, then I've used it wrong...

I think you did it correctly, 2.4 has around 3500rpm at 80mph so dropping it down to 2700 would be MASSIVE improvement :slayer:

Assuming of course that most folk have a gear shaper/hobbber/grinder stashed in their Shed

Does anyone know where the reverse light switch is located? Pictures would be helpful. Thanks!

Does it's location interfere with a 6 speed box being fitted then ?, if not the relevance is ?

So time has passed and I still haven't decided to tweak Stilo's gear ratios but lately I came across something I'd call good news. Some guy from Fiat Stilo Club Poland has told that the main problem with swapping in 6-speed box is the diff housing and that he's working on it right now. I hope the results will be satistyfing, I could then use the knowledge or drop my car at his spot for him to help.
I won't lie, swapping the gearbox is my number one solution so if there's any chance that would work while keeping the costs at bay, i got to try it.

Stay tuned for some more informations.

One way street.. a long way away..

There are a number of car programs where they change roofs, change chassis, and just about everything else. So, to chonk some bodywork to give clearance for a different diff housing doesn't sound too difficult .

However, there's a world of difference in doing it to a stripped out engine bay in a full size, fully equipped workshop, to doing it in your garage or at the side of the road with a few spanners and a trolley jack

Allegedly , but he wasn't forthcoming on details etc, which had it worked, he would have surely only been too happy to divulge
