5 speed conversion

• Page 1 of 2 • 1, 2
I completed a 5 speed conversion for my Plus 2 using an alpha box last year, final drive is .78 with a 3.55 rear cruises very comfortably. We made a 1" aluminum adaptor to mate the original lotus bell housing to the front of the ALpha box. Fit in the car was very easy, kept the originial shifter location, very little fitting problems. Biggest hassel was the spreedo conversion but that looks to be solved as well. Have about 500 miles with no problems. Any one wants to see the car in Massachusetts or learn more, drop me a note.

Hi Rick
Good to see someone local doing all the engineering, I would like to take a look some time. Its been a while (92 or 93) since I have been out your way. I stopped at your shop and met you an Noel Poduje. Thanks for the info

Rick,
Count me in for a visit as well. Gary seems to have been a more recent visitor, I don't think I have been out your way for at least 15 years. I have not seen your +2 since the first LOG in Connecticut when you were there with your race car as well. I seem to recall your +2 is very close to mine in terms of chassis number. I have been thinking about going the way of the Alan Voights Ford T9 conversion. I am very interested in all the details, ratios of each gear etc.

Gear box was out of a Giulia, ratios: 3.304, 1.988, 1.355, 1.000, and .791. Speedo converion used the stock right angle drive with a new retaining nut (cut for meteric threads) and a ratio adaptor spliced into the speedo cable from APT(http://www.gaugeguys.com/). Also had a custom driveshaft made. All th original clutch components can be used save the disk which is a different spline but very available. For my conversion I close to convert to a annular slave cylinder(Dave Bean amoung others) while it was easy to design a mount on the adaptor plate. Had some modificatios made to the gear box rear housing for clearance and mounting but nothing major and only needed minor welding for a tranny mount.

Hi Rick
I will talk with Russ and a few other interested parties to establish a good weekend date, that way you won't have to show it off to many times.

I found this page on Alfa Giulia gearbox with photos of a strip down, not sure this is the one Rick is refering to but the shift is in the right place. the donut on the back has me worried though.

If you have done a CV joint replacement the donut might be good to give you some give in the drive train. Many modern cars have rubber discs in their drive shafts.

Gary,
Please sign me up as an "interested party." Rick told me about this conversion while we were discussing the 1700cc engine.
Thanks,
Andy

Hi Andy
Bill Gavin is interested too. sounds like Rick is in for a flock of Lotus nuts to show up and paw all over his Plus 2. I am interested in the F.I. 1850 engine in Danny's car too.
