| Brian - You can use your XE head, but that will require dismantling to fit the LET cams. Or you can use your XE cams for a bit more hp, but you would have to fir vernier pulleys and that would require an expenditure of more then £4.99.
Stef - The pipes are spanky. Thank you.... Mwah
JapCav - You'd be lucky to get more then £10 out of Brian for something new when he can use a 2nd hand belt for £5.  . Is it for a late engine?

see my for sale thread or pm me | Hello Laura. I believe I have a late LET, so I dont think your belt kit will fit  Thanks for letting me know though. 
And Dave, I cant re use the old kit, I had to cut the belt off.

| What is the difference between Let cams and XE cams then?
Sorry for these questions, we've all got to learn somewhere. | |

| Brian, seriously, staples cost about 0.0004p each. You could even buy a pack of 1000, use four or five, then hand the pack back for a refund! Thats a free cambelt! Quote: |

Turbo cam timing is so massivly different to N/A cams the mind just boggles. I dont think there is anyone on the planet that knows it all 100%.
General concensus (as I have done) is to use the XE inlet cam and stock LET cam. Inlet needs retarding 6 degrees to time properly though. | |

And the retarding is done vai the Vernia pullys then? If I fitted both the XE cams with Vernia (Sp) pully's then and got them set up on a rolling road, that would be a couple of extra BHP? Especialy if I use the Ported Coscast head from the XE?
BARGAIN.... | |

BARGAIN.... | No mate it dosnt work quite like that. You only fit the Inlet due to the cam timing. | |

| Chris. This is Rob from Braintree. Not on MIG. He builds racing engines and Dave and Stefan in particular have become close freinds with him along with Dan and I to a lesser extent. Stef even works with him on a Saturday to get experience.
I will PM you some prices I am looking for those bits. | |

| OK mark. the red should go with your Calibra OK. Comes with a Red Hose and clips as well. 
I have had a couple of Gin and Tonics while watching dan install his xenon headlights so not the right time to think of anything right now, Wow, I should have used the measure, my head is nicely spinning. | |
