SR2 build
lee@RRR - 27/5/10 at 10:52 PM
hi everyone just signed up thought i would say hi and do a build dairy on my SR2 as you can probably work out from my user name i work for road runner
racing so decided i would build myself a SR2
ill be using 1600 mx5 running gear with a full built engine and a rather large turbo previously i have had a big power evo and a 300whp mx5 so getting
good power from the engine shouldnt be a problem
not had alot of time on it so far the parts are piling up but with only the odd 10mins between building customers chassis and getting kits ready i
have only had chance to get the master cylinders and brake lines on
gone for remote resevoirs as i already had them lying around from another project
set to mocking up were i want the turbo to go so i can build the manifold
test fitted to one of out full built cars to check clearence

looking good
Although...
That bracket for the brake fluid etc it’s going to flex and vibrate the way its mounted and then fatigue at the rivets, then fall off. You’ll need a
much stronger mounting method and I’d make it from steel. I’ve had driving lamps fatigue 2 inch perfectly round holes in 3mm aluminium sheet purely
from vibration.

bloody puzzles lol by the end of the weekend i could manage it with my eyes shut

i think possibly driving lamps are heavier than the res pots personally i think it will be fine its got more than enough rivets securing it and it
doesnt span a great distance so there will be very little leverage

Looking forward to seeing this build. If i were to build another car i would go the full Mazda Mx5 Route. Out of interest, why did you choose the 1.6
over the 1.8?

If I had to start a kit , this would be the same as yours : This chassis is just amazing!

I agree, Welderman and me were at the show and were impressed by that chassis. The body is a very nice fit too.
I had a good chat with you about the SR2 and have just put my Caterham up for sale with the intention of getting an SR2 to build.

Hi
Good looking Turbo, What BHP will you get from that and what pistons and rods have you put in.
Can a Turbo be put on a standard engine and what BHP would I get without damaging the engine ?

Yes a turbo can be put on a standard engine. The older engines in the Mk1 run slightly lower compression as standard than the engines in Mk2, so
mapping will be slightly different. Should be able to get to around 200bhp without any problems

hi, lovely looking car, really like these rrr cars. good luck with the build.

its a gt2876r ball bearing its good for around 450-500bhp im hoping i should at 2 bar of boost for around 400whp
ill be fitting weisco pistons and carillio i beam rods
the standard engines are fairly strong i have personally had 250whp on a standard bottom end at about a bar of boost
we are as a company planning on offering a turbo conversion in the near future just finalising a few things and some testing

What does the chassis weigh Lee?
lee@RRR - 4/6/10 at 10:41 PM
little update
got the manifold done
ecu mounted and started making the engine loom
pistons and rods arrived
should get the block across to be machined early next week and then set to building it up
Steve Hignett - 5/6/10 at 01:44 AM
And, err, what does the chassis weigh Lee?
To be fair, Chris has only just this week told me what his weighs, so I could pass it on to Tim and I forgot it, before I'd even put the phone
down!!!
I suppose I could just ask him again!
lee@RRR - 5/6/10 at 06:41 AM
Ill weigh it when i get into work today mine will be slightly less as i dont have door bars
lee@RRR - 5/6/10 at 06:03 PM
