Just in case you encounter the same problem: The solution? I took the bearing to local machine shop and reduced it a little bit. The upgrade transmission is now back in order. Thanks for the help!

Matt is right! Next time, while the car show in Massachusett beach show us some chowder chassis.

Thanks Neil--- Here is the picture:

ok guys thanks...i will wait monday and talk to him. by the way, i cant find his new website This one is not working http://www.gtoengineering.co.uk/

Thanks Neal: At one time, I had his cell # but I lost it. I will see if I can ask his cell, sometimes people don't give their cell #. I will measure the original bearing if 62mm or 52mm, then I will measure what he installed in the shaft. Neal by the way, do you happen to know the bearing brand and part # of the 62mm and 52mm? Worse to worse I might be able to cross reference here in the US. OK...I measured the original Lotus bearing and you are correct 52mm. I measured what GTO gave me and its 52.04mm so where do I go from here? Neal said: Kevin supplies a new bespoke bearing for the upgrade to fit your casing. What bespoke bearing means?

Thanks Chris appreciate your help. I tried to call him a few times but he is not around. He will be back on Monday. Wow! you telling me the 5th gear bearing has different sizes and perhaps he installed the wrong bearing on the shaft? If there are several options, this is a good news. I will email him today. Thanks

Anyone fitted their V8 Transmission with GTO stronger shaft upgrade? I need help & question: I bought the upgrade shaft from GTO engineering. The kit came with new 1st, 2nd gear and the 5th gear bearing installed in the shaft. Everything fits except one thing. The fifth gear bearing is oversize (little bit), when I closed the transmission cover case, there is a gap and will not sit properly. The bearing sitting in race groove is bigger. I need some advice from those owners who upgraded their transmission shaft. Can I heat the transmission case cover and freeze the bearing then install the cover case hoping to decrease the tolerance? The next solution is to machine the case bearing groove ? Note: the original lotus 5th gear bearing has a circlip. The one came from GTO engineering, the bearing circlip is machined (build in the bearing not a removable circlip). I noticed this is a little wider. Maybe this guide is not sitting properly in the groove? Please help! thank you

here we go, dont know if i'm brave or stupid, time will tell !! Don't worry, since the invention of internal combustion engine (1806), there is no changes. Still a combustion engine today. If you have done a rebuild before, you are still dealing the same old technology. Push-compress-power--booom! Just be careful.

Clutch is not your priority. There is a big job ahead. If u have a gearbox problem, you can hope that you are just dreaming. Broke a gear and jammed, perhaps ?

What's wrong with your gearbox? There are few options where to buy the twin disc clutch in the US. JAE (California) sells the twin disc http://www.jaeparts.com/ over $1000 ! Michael Motorsports in Massachusetts sells two different types http://www.michaelsmotorsports.com/ You can also send your worn out twin disc to "Clutchnet" http://www.clutchnet.com/home.php and rebuild or reline (cheaper route $200.). Make sure the thickness is the same as Lotus spec 7mm. You can go over 7.5mm but no more than. I bought mine from GTO engineering(england). Kevin gave me a racing twin disc. He claimed this parts far better than the stock. You need to replace your pilot bearing, might as well change your main seals and driveshaft seal. If your clutch pressure plate is bad...that's another story. I replaced mine. I also bought the transmission upgrade (main shaft) + ATB quaife from GTO. Hope helps. Email me if you need help

Re. the chargecoolers, these are not the same as the 150 quid Ebay ones. It would have cost about 1K to replace the chargecoolers vs. a couple of hundred to cut open, clean and weld/polish. When are you and Alan going to let us see some of your chargecooler work? Mike's chargecooler are not the Chinese copy. Looks like a real Spearco design. Chinese copied the spearco intercooler and dumped it here in the U.S for a penny (Ebay). I saw the copy and its identical. Same thickness and the workmanship looks fine. I think its good for consumers but bad for business. When you imfringe or hijack someones design, you should go to jail. I did not use the spearco in my chargecooler design. I used two Garrett intercoolers that came from Syclone/Typhoon. Fitting chargecooler will develop lag if not configured properly. The length of the pipes and the size of intercooler is critical. I'm lucky I choose the Garrett size. The response is instantaneous with no lag. Trial and error but got lucky this time.

You will be surprised the Lotus tech will find nothing. But later, it will happen again. Its master cylinder!

I had mine done in the states using Volvo blank.

sorry my bad...it the saturn

I know someone has 4 sets from 2001 (excellent condition like new) I will ask him tonight.
