The 9000rpm 80mm tacho is £105 inc. vat
Link Display is £200 inc. vat, tein said to be aware you obviously need all the sensors for it to do anything, which you'll already have if you've got defi gauges of course...
Both are in stock.
Cooler/relocation kit, the one in the shop will do the trick nicely, it's what I've got on the chaser. Comes with metric and imperial oil filter fittings for the block and then you just use a metric filter such as an SR20 one on the relocation plate.
Smiths gauges, errr, maybe but I'm not sure where from. I'll check properly for you if you can't get em elsewhere.
