  1. I've got one fitted and I wrapped the wastegate discharge as well. They do make a tremendous difference in engine compartment temperature, but the materials don't last. The turbo blanket will smoke for about an hour when first installed as about 0.5" of the ceramic packing closest to the housing turns to ash. After the initial "burn in" wear is much slower, but after 18 months or so depending upon how hard the car is driven the thread holding it together will burn up and the blanket will begin to fall apart. Any metal touching the outside of the blanket, such as an O2 sensor, will burn thr
  2. The Renault UN1 transaxles are fine up to about 350 ft-lbs of torque. It's torque that kills gearboxes not HP. From personal experience with a new gearbox, under hard use I had the following issues: 1. The Lotus shifter is garbage. Light, but vague and sloppy. The UN1 is capable of delivering excellent feel with no slop, but you'll have to craft your own shifter/linkage. I've done it and can send photos if desired. 2. The second gear synchro is slow, perhaps due to the mass of the gear or the inverted cone design. To avoid graunching upon upshifts you need to pause a half second
  3. It depends on the pump you plan to use and its current load. I run a WC Engineering pump on my '87 HCi. The current draw is low enough that it can be connected to one of the fuel pump circuits.
  4. Andy, my car is a US car with a composite roof. They use a smaller version of the striker pins and latch similar to the deck lid. I agree replacing the roof seal will increase tension and reduce rattling of the roof, but notwithstanding, if the latch is functioning properly, the pin shouldn't be able to to get past the latch plate. The roof only pops loose on one side. I'm thinking the riv nuts that secure that the bottom part of the latch were not properly aligned when the car was built meaning the latch doesn't properly secure the striker pin. The build quality of this particula
  5. Has anyone had a problem with the removeable roof popping loose when going over the slightest pavement ripple? Mine pops loose incessantly on the passenger side. Neither the pin nor latch show any signs of visual wear and I've tried every adjustment possible with no luck. Has anyone come up with a fix or upgrade?
  6. From these guys. http://www.rbttrans.com/ The front office, Lloyd Buttfoy, is not as accessible as one would like, but he knows his stuff and is 100% honest. Lloyd has the production rights, handles new orders, rebuilds and after sales service. Manufacturing is in TX. If there's a problem he can get a part from TX in a day FedEX. I speak from experience. They stand behind what they build. M---
  7. The transmissions are about $9,000, but there it was more work than expected to get it into the car: Clutch The release bearing setup New half shafts (Renault box cans can have the old ones shortened) Bell housing - Quaife for the V8's or Conversion Components in NZ for the fours (I paid for the casting pattern, it would be nice to see it used more than once). New shifter or shifter modification, custom cables and working out linkage ratios and details Fabrication - adding a rear shelf to the rear hoop, removal of the old gearbox mounts and replacing the lower frame rails (need to be d
  8. To all. For a parking brake I use a Mapco hydraulic parking brake. Not DOT but works great once you change the 0-rings from neoprene to EPDM. The gearbox is an RBT DS25/2 made in Texas. RBT bought the rights, tooling and NOS from ZF. The great thing is rather than buy an OEM production version, the boxes are built to order, allowing you to mix and match features from any ZF DS25 ever produced. Mine is based on the BMW M1 version, which has CV joint output shafts, the shortest input shaft available M29 x 10T 4.25" long, a stronger case than the Pantera versions and upgraded synchros.
  9. It wasn't easy. The prototype took about 16 hours of machine time. You start with almost 20lbs of aluminum for 2 lbs of brackets. The first set were made for calipers with ears. Having the basic design worked out, this second set for radial calipers took about a day on a mill, plus fitting, shimming and minor adjustments to get the calipers centered on the rotors. With this design, the minimum disc diameter possible is 12.5". I run 13" at all 4 corners, 6 pistons in the front and 4 in the rear. First the outboard nose of each upright was machined round. The brackets were machined fro
  10. Mark, That may be tough without changing the bulb holders; the bulbs are screw in while most of the LEDs I've seen are the wedge push in or bayonet type. These guys have a fair selection, you might check with them: http://superlumination.com/1156_1157.htm If you can, go with lamps that have 3 LEDS in them, single light bulbs will be too dim. More than 3 LEDs usually means a bulb head to large in diameter to fit inside of the green lens inside the gauge. britishwiring.com may be able to provide you with new bulb sockets It's also possible that the new Smiths Classic range use
  11. Here's a few pics of my work in process. I've taken the same approach with my old Esprit as Caterham has with the Seven. Think of it as the G-car equivalent of a CSR260.
  12. Spin the oil pump with an impact wrench with the timing belt removed, connecting the oil outlet to the inlet, if the adapter is in place. Better not to crank the motor, the pumps take some time to prime and produce oil pressure. With an impact you can pressurize the motor before it even turns.
  13. Excuse me, but I should have specified. My comment applied only to the US Federal Elise with the Toyota motor, as per posts on Elise talk forum. I'm not familiar enough with the ROW K motor cars.
  14. "While I was re-doing the head gasket on my elise and about to fit a remote thermostat, I realised that the Elise uses an electric water pump to assist the mechanically driven one." The electric pump in the Elise is to improve circulation to the heater core, not to improve cooling.
  15. I went for an inch. Doing so allows you to port the diffuser, opening the inlet about 0.25". In theory you should go as large as you have room, but there are physical limitations. You'll also need to make a new manifold brace, reshape the dipstick tube and make a "V" support piece with the tube clip to support it. Try to go 2" and the adaptation becomes more complicated.
