stainlees 1300 valves,
Turbo Mini Forums

hi,bit of a long shot, but im looking for a set of stainless race type valves, pref 33 and 29mm

would consider good used condition. please pm with what you have. cheers

My experience is that second hand stainless valves are always worn on the stems. New ones are £8 a piece from Minispares. No brainer really.

Which guides have you got?

Going for bronze guides

Then go for new valves from Minispares as well. Or, you could be really trick and buy some Rimflos from Paul Ivey. They are almost the same price, a tenner IIRC, and have hardened stems so last forever. Great guy, great service!

I wonder if its worth it then.
Its for mpi engine running 1360 cc,sw5i cam,ported/polished head,matched manifold,maniflow lcb 1.5 roller rockers with double springs,52mm throttle body.comp ratio of around 10.6:1.
Running with close ratio gearbox with 3.2 fd.
Think the valves would make a difference?know what i have wil be running near to max power for a mpi.

For low revs and longevity, I'd DEFINITELY choose either standard backcut A+ valves or Rimflos.

i wil stick to standard then as on tight budget. not sure the stainless valves will give me anything in way of performance. what is involved in back cutting standard valves?

You need a lathe. A 30 degree angled backcut is applied to narrow the seat down. It's explained in Vizards book.
