42mm & 50mm inlet manifold ?

As Above

How do you tell the difference ?

 

One's bigger than the other, have a look in the pinned 2 litre 16v thread started by me..

 

Three different sizes.
1.41mm
2.42.5mm
3.50mm

This is a 41mm with raised casting on first inlet.


42.5mm doesn`t have this and a 50mm has narrow section to allow HT lead to be inserted.
Loads of threads on this very subject so have a search.

 

Are you certain thats right dave as theres always someone with a different measurement Ive got the smallest 1 now and car feels alot livlier over the 50mm jobby

 

Wots the difference does the 50mm one increase top end i know its the euro part ETC but is it ACTUALLY noticable gain?


Thanks

 

I wonder where you're from?

The 50mm supposedly gains a little at the top end over the smaller ones, at the expense of some mid-range torque. It's not a huge amount tbh, everyone you ask will have a different view of whats 'best'.

 

Everyone says different about which is best.

In reality, there is probably little in it.

Mines got the biggest one on and goes pretty well for it.

 

So I take it this one is 41mm


Also are these interchangable

 

Yes x 2.
As long as it is both sections.
