I am putting a 2.0 silvertop into a fiesta mk3.5 si 1.6, I want to fit an rst turbo lsd gearbox at the same time, is the series 1 or series 2 the best option, and which is easiest to fit.

S2 box is better as it was a more road-friendly LSD than the motorsport-bred S1.
Also Im not 100% sure on this but i think the S1 has different mountings so more work to fit whereas the S2 will bolt straight in
With regards to ratios, the S2 box ratios arent too far off the rs1800 fiesta box, same final drive ratio, and same 2nd gear. all other gears are relatively close between boxes

I wasnt sure about them both bolting straight in because the S1 gearbox has a different casing than the S2 so thought there was a bit of modding needed to make it fit.
On the ratios;
Fiesta RS1800 mk3
1st 2.86
2nd 1.91
3rd 1.41
4th 1.10
5th 0.87
Final Drive 3.82
Escort RS turbo S2*
1st 3.15
2nd 1.91
3rd 1.28
4th 0.95
5th 0.76
Final Drive 3.82
From the RPM calculator I was using when i trying to decide for mine there wasnt a whole lot in the difference but not having driven both I suppose I cant comment accurately
