I only ever run in Supersprints here in Adelaide, which is basically your average street car with no limits, my car was much quicker than most Historic cars because of the freedom. I wouldn't want to go back to a 4 speed and R160 and lose my Webbers for SU's!!!!
It all depends how competitive you want to be as there are plenty quick cars in improved production! The diff weights would be a bit more than a couple of kilos for and R160 - R200 comparison but I have an R180 4.11 in my car and didn't notice any difference in handling etc. 5.1 would be good for hillclimbing but I found the 4.11 a good compromise for all round driving (road, track , drags) but maybe a 4.4 would be slightly better on acceleration. It all depends on gearbox ratios, tyre size etc. Regards Dan G -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jeff Oldham Sent: Friday, 4 June 2004 11:35 AM To: [EMAIL PROTECTED] Subject: RE: Installing Subaru LSD Importance: High Yeah datsun 1600 is the intended recipient I am currently torn between the whole historic thing & just going improved production which free's up a lot of stuff..... historic your stuck with mostly original "casings" but internals are free so stuck with r160 diff housing but free ratios etc same with gearbox......stuck with 4 speed, but any gears u want are OK in some ways it seems to make it harder & more expensive not cheaper....... one of the guys who runs an historic 1600 reckons the bigger diffs are to heavy and i suppose saving weight is good.....but there cant be much difference can there ? maybe a couple of Kilo's at worst i suppose ? I am wondering if it will end up being easier & cheaper to just go improved production there is certainly much more freedom. Oh & you can advertise on improved production cars, but not on historics ! I currently run in "road registered" class. I really fancy the idea of a 5.1 diff ratio as a cheap speed maker for climbing those damn hills ! QLD hillclimb champs this weekend 5th & 6th Gramzow rd Mt Cotton (south of Brisbane) Saturday you might get in free as its practise day, but Sunday there will definately be a charge sorry, but i dont know how much, club meetings are usually free for spectators. Believe it or not the old 1600 is not always the slowest car there even though it has still got stock running gear & suspension !, QLD champs though should see some quick cars turn up ! I am rambling again so better go :) anybody turns up on the weekend come for a chat if you want white datsun 1600 no.66 cheers Jeff Subject: RE: Installing Subaru LSD I've got a list of ratios avail for each diff R160, R180 , R190, R200 at home. I'm pretty sure a 5.1 for an R160 would be hard to find and the bigger ones won't fit in the R160 case. I believe a bigger diff is better in a 1600 (is this what its going into?) as they benefit from the extra weight down back. I would go for the R160 subaru LSD in 4.1 or 4.4 with either a Z 5 speed or similar (depending on the Historic regs?) as these would be easier to find than the Datto ones in R160 size.
