Just an update on this labour of love..
The auto flywheel that I purchased could not be used as the steps in the flywheel fouled with the alloy clutch hub which is used to hold the 5.5"carbon clutch so I removed the centre of the flywheel leaving the ring gear. This worked out well as no Ihave a clean slate to work with. I had a 3mm x 3mm groove cut into the ring gear from which measurements were taken to fabricate a new body for the flywheel. This was CAD designed then cut with a waterjet cutter to a tolerance which was then machined down for an interference fit with the groove in the ring gear and the alloy hub for the clutch. All the holes which are found in the auto flywheel were also cut but the mounting holes for a tourque converter were enlarged to save some weight.
The ring gear and flywheel body was then mig welded together then the alloy hub fitted then off to to be balanced at Dominator engine builders in Guildford. This guy has been a legend speedcar builder for 40yrs.
Today I finally installed the new flywheel and clutch back into the car. Gearbox is also fitted. Clutch slave cylinder, axles and thats it till tomorrow. Expect to have the starter installed. I used a Toyota Echo starter which is just under 3kg lighter than standard MR2. Hope it can handle the pace..Engine and gearbox mounts, subframe, control arms and toe links. Wednesday will be a few odds and ends then ready to start.
Other additions will be a trans cooler, oil catch can,full undertray,alloy inlet pipe, additional fixing to the rear camber adjustment. There are still a few other unfinished items that need to be done which will also be sorted in the next week. All night work this week but really want it on track in two weeks for EC practice then hopefully race at Wakefield Park on the last weekend of the month.
I had a look at a friends RX7 rear suspension assembly over the weekend. There is a strong chance this can be fitted to a MR2. Watch this space!
For all the power junkies out there I have also confirmed the purchase of an engine which is brand new/fully rebuild never started. 2.2ltr, rally spec head, all the fruit including cams, adjustable cam wheels,etc. Made to handle over 600hp. I expect to have it later next year so will be gearing up the fuel system to suit as well as inlet manifold,ECU etc.
The new goal will be 990kg/500hp, new undies...
