hedgerley Posted January 4, 2014 Report Share Posted January 4, 2014 South West Lotus Centre have been advertising new V8 pistons for some time Alex - http://www.lotusforsale.com/ads/lotus-esprit-3-5-v8-forged-pistons-set/ And I have a bunch of valves, cleaned up and undamaged. PM me your email address and contact details if interested. Quote Link to comment Share on other sites More sharing options...
steve930 Posted January 4, 2014 Report Share Posted January 4, 2014 Pistons are probably from the American division of G.M. if they were used in other applications. There's quite a few American gm parts used on & around the engine Quote Link to comment Share on other sites More sharing options...
Alex Carter Posted January 5, 2014 Author Report Share Posted January 5, 2014 Yes gm Steve but what ..... and please hedgerley ill pm you thanks Quote Link to comment Share on other sites More sharing options...
Alex Carter Posted January 5, 2014 Author Report Share Posted January 5, 2014 I know the v8 forged pistons are available from SWL but 1600 for forged! Lotus used other parts so there GM they must be more common and used in other cars for cheaper from the states ! Take for example my clear side repeaters from lotus with a lotus price tag 120 odd quid from the Renault owners site same part same size same colour same model 19.99 that's my issue I'm not a tight ass but I'm not a fool either Quote Link to comment Share on other sites More sharing options...
Bibs Posted January 5, 2014 Report Share Posted January 5, 2014 Someone was ripping you off, the indicators are £21.65 from Lotus! A082M6535F Description: Lens, side repeater. Notes: Qty on Car: 2. Price (each): £21.65. Stock: Factory Without busting your balls, you'd get a 5-10% discount with SWLC as a FFM and also 10% from many main dealers. That £20 could be saving you a fortune right now...

Trevsked Posted January 5, 2014 Report Share Posted January 5, 2014 I'm inclined to think like Buddsy that the pistons are Lotus specific. Lotus being an engineering company would probably want to specify these and of course I doubt South West Lotus would go to the trouble of having forged items produced if an American alternative was made. I hope I'm wrong in some ways as possibly at some point I will need to sort something like this but the SWLC price doesn't sound unrealistic is they are specific items. Trevor.

t70 Posted January 6, 2014 Report Share Posted January 6, 2014 I may have my Pistons available soon.. They are forged, with only about 2000 miles on them. How soon are you in need of said pistons?

Alex Carter Posted January 6, 2014 Author Report Share Posted January 6, 2014 (edited) Oh whys that mark no massive rush going to be 3 months to get valves made anyways what do you have it is a v8 isn't it lol Edited January 6, 2014 by Alex Carter Quote Link to comment Share on other sites More sharing options...
Alex Carter Posted January 6, 2014 Author Report Share Posted January 6, 2014 No buddsy standard metal no sodium that's just the 4 poppers Quote Link to comment Share on other sites More sharing options...
Bibs Posted January 6, 2014 Report Share Posted January 6, 2014 The sodium liquefies once up to temp and acts as a momentum damper in the 4 pots. I can't remember the name of the metal used in the V8 valves but it doesn't need to be damped like this. Is it molybdenum?

Vulcan Grey Posted January 8, 2014 Report Share Posted January 8, 2014 The sodium in the 910 exhaust valves, along with the silicon-bronze valve guides are used to transfer heat away from the valve face and into the head, to be cooled by the water jacket in the head. That is why they are only on the exhaust and not on the intake as well. Quote Travis Vulcan Grey 89SE Link to comment Share on other sites More sharing options...
sailorbob Posted January 8, 2014 Report Share Posted January 8, 2014 Forgot to mention that the exhaust valve stems are chrome plated. Quote Link to comment Share on other sites More sharing options...
