L67 Engineered Gem

[NOG181_l67gem]

Just got myself a glimps of yours on ya website that's under construction, JEALOUS some, yes I am, that thing not only looks sweet must get up dance man, I seen on an ep of grunt files years ago a elderly lady had a gem wagon with 202 and triples etc, 11.70's or something stupid, let alone injection turbo setup on one, v6 slotted in reasonably ok but couldn't imagine straight 6 would leave much room for a spanner lol

yeah that lady I believe is the person (well her and her hubby till he passed away) who run the 6 banger nationals at warwick!

if your interested in seeing the details, its all in this thread http://pcmhacking.net/forums/viewtopic.php?f=16&t=9

Yep that's the one, good on the old duck, it's great to see her still racing, then u see it's in a202 gem wagon yyuuuuu

yeah that car was about the only one I was able to find of a 202 in a Gemini before I did mine, most people from what I've heard used to have the motor forward more so you didn't have to change the tunnel/firewall and gearbox/tailshaft, then just cut the front out and have the radiator forwards, but I had rusted out floors anyways and wanted it back for better weight distribution which also means I have been able to fit a big radiator in without too much cutting! anyways i'll stop hijacking your thread

on the subject of yours though, I assume you've just had the security removed from the tune to allow it to run in the Gemini ?

Awesome car, nice work!

Thought id throw a little info and pics of the diff while its apart

Ive used standard gemini diff but after about about half a dozen snapped axles had to try something on the cheap to strengthen it, so on the phone to engineer friend and put passed him using a borgwarner mini spool inside gimini centre and get commo axles machined down and resplined to suit

[NOG181_l67gem]

Here is an axle that was made to suit, just used 28spline commo axles shortened and machined down also resplined to 25 spline to suit mini spool, i used gemini bearing and axle seal, gotta love holdens interchangeability

[NOG181_l67gem]

Quickly just slapped it together before putting in, make sure shes all sweet

[NOG181_l67gem]

Finally took a couple of pics with the 19psi of love pulley and ls1 maf fitted, just waiting on nvram from the The1 with his enhanced tune equipped then a few little changes etc in which hopefully he can assist me with and will try get the full 19 pounds of goodness out of it, shouldnt b a drama considering with stock maf was getting 17psi on a cold night

I reckon those axles could break at the machined down part since the twisting will now concentrate on the thinnest part. Also the stock commodore axles have rolled splines not machined ones which are strong as it effectively forges the splines.

Was there a reason why you couldn't have used 28 spline center or spool? Oh yeah and spool would add to the stress of the axle. I've seen plenty 28 spline break from the spool alone in stock cars due to the twisting in opposite directions during turning.

If it was me, I'd get a trutrac center with axles made up for it in 28 or 31 size
