2.1 Vs 2.2

[blandy 29]

I have been reading most of the 2.1 or 2.2 xu10 projects in the last few days.

 

The main question really is what are the benefits of 1 over the other. I.e i have a 88mm crank here to go to 2.1 but thinking along the lines of i am going to need custom rods/pistons either way so would probably be better looking for a 92mm crank and aiming for 2.2.

 

I just see most people go towards 2.1 but from the offset 2.2 seems more like the obvious choice?

 

Again for ease/cost would be looking to run a hydraulic profile cam so something like cat cams 109 etc

Why not 2336cc?

Reading through the old threads there seemed to be alot of uncertainty from going to 88mm bore was planning on going for 87mm

Dan means EW12, so I guess he missed this is in the XU section

96x87 ftw

Whats your current set up Welsh? are you 2.1 or 2.2?

[welshpug 1,657]

2187, so 2.2, 92x87.

[blandy 29]

So as I can see there's no real disadvantage to going 2.2 over 2.1?

 

Is this the correct crank

A bit of a hi Jack. Sorry.

What cc would 100x86 mi16 top make?

[welshpug 1,657]

about 2324cc

 

not sure if you can even make 100mm work.

 

dan has had a maths fail, 96x87 is 2283.6cc

 

96x88 is 2336.4cc, which he wont be going as he's already bought some 87mm pistons

 

 

xud11 is the 92mm crank yes, that's about £100 more than I paid for my crank I think!

[blandy 29]

do you know what yours made in the end Mei? As your still on hydraulic profile i believe?

 

Just like the idea of not having to rev to the moon and also a nice shove of torque

[welshpug 1,657]

not sure exactly, ph4's piper springs and hydraulics, 240 ish as I've maxed the gti6 injectors, the clio outers are filling in the rest.

[blandy 29]

Id be more than happy with 240ish
