Is this worth it?

[chris g 0]

I've found a company that can refurb my 2.0 16v head. They can do it to stage 3, 4 or 5.

 

Stage 3 is fully recon'd with new guides, tripple cut valves, ported and polished. This is £560

 

Stage 4 is as above but with stainless oversized inlet valves £??

 

Stage 5 is as above but with stainless oversized exhaust valves too £1000

 

Which should I go for and are these prices reasonable?

 

Cheers

i didnt think there was enough room to fit oversized velves on the 16v head..i may be wrong but im sure thats what tsr told me when i enquired about one for my old golf

The problem is that when you make them fit the space between the seats get smaller and smaller and this adversely effects reliability.

I would just go with the port, polish and 3 angle seats. Fairly certain to get 160 with that, more with cams.

They are only .7mm oversized. Doesn't really seem worth double the price to me!! I'll go with the stage 3 I think. I've got a KR intel cam to go in and i've got a brand new exhaust manifold that i'm going to get matched to the head.

 

What gains do the 50mm inlets give?

Someone on club gti forum gained 1bhp and lost loadsa torque fitting a 50mm!
