  2. Hello Pan, if you are targeting 400hp EFR 7163 would be better suitable (pn.11639880002) 7670 is too large
  3. Hello Pan, what power level are you plan on running? G25-660 is a very good unit, fairly compact for the flow with very high EGT capability and available as a integrated wastegate unit as well. But spool-up of the EFR is better due to TiAl turbine which is 40% lighter than standard wheel material and 50% lighter than G25 high temp material, so if you don't go for more than 500hp i think EFR would be the better solution. But if you go over that it might be easier to fit G25-660 over EFR 7670 packaging wise.
  4. Easiest / most reliable and most valuable route is buy a V8 or improve the 4cylinder turbo to the 350 hp mark. All power and related torque above will kill the gearbox. For sure don't go for a VAG W12 which is a horrible engine on all aspects. But if you would like to go special, I have seen a V8 build from something like a Rover base block with 2 Lotus 4 cylinder 16v heads. They displayed it at the autosport show a few years ago. https://jalopnik.com/this-rover-lotus-biturbo-v8-is-the-ultimate-franken-eng-1694045433
  5. I'm curious why the Esprit (GT3) has a expansion tank above the left rear wheel in the luggage compartment? What happens if it is cancelled.
  6. Thanks Dave, I ordered the V8 CWP from SJSportscar. Now changing to another gearbox is a bit to late. Maybe in the future first I will try my luck with this setup. Cheers, Jaap
  7. Hello Jon, Not sure on the boost required yet. I suppose between 1 and 2 bar. Thanks Dave, From SJsportcar I got the info that the GT3 pn for the CWP is A082F6584S while the S4s/V8 is A082F6484F so I will buy the V8 CWP. Still not sure on the GTO primary shaft, the changed gearing for 1 and 2 is not to my liking. I'm also checking the EMCO upgrade only EMCO's response is not great.
  8. Thanks Barry, I just found your thread on the V8 discussing this topic.
  9. Thanks for feedback, definitely need to look into the CWP issue. We will be aiming ~350 hp, with the following updates: Alunox / vdlee twin scroll, ball bearing turbo setup EFI e4 ecu Upgraded conrods Deatchwerks injectors Direct ignition coils on spark plugs PNM upgraded clutch So with the new turbo setup we should improve low end torque supported by the upgraded PNM upgraded clutch. Although 350ft lbs sounds a bit high, I don't think we would go over 275ft lbs. Car is now on the standard 17" wheels but considering 18" for the rear in the future. Then on the CWP i was not aware there were different specs, I can only find A082F6484F in the parts list but not sure which one this is.
  10. As we are rebuilding and upgrading the GT3 920 engine for improved power and torque I'm considering to modify the gearbox with a upgrade primary shaft. Either the Holoway kit or the GTOracing kit. My only concern is the new gearing on the 1st and 2nd gear. I frequently use the car for long trips around Europe which always contain some heavy traffic driving conditions. Is there experience with either a GT3 or other 4 cylinder cars with these kits? Especially with regards to the new gearing.

  13. Congratz! We have a winner.
  14. Quiz question, there seems to be one car missing from this selection of cars at Topgear? Lamborghini Countach, Ferrari Testarossa, Lotus Esprit, Porsche 911, .........?
  15. New decision making, first new injectors. Decided on Bosch EV14 by deatschwerks. Should be OK for up to 330 to 350 hp. http://www.deatschwerks.com/products/fuel-injectors/bosch-ev14-universal-line/4-cylinders-ev14/long-60mm-ev14-4-cylinders/18u-00-0050-4-detail

  17. Trying to translate the wiring diagrams from the manual to a schematic. Just not sure if it is correct. Any thoughts?
  18. Installed the PNM "Lotus Esprit Front 323mm Disc Upgrade" with grooved disks. Absolutely fantastic! Very good bite and control now. Next upgrade damper and springs. Just checked with the local dealer but het can't source the parts! Are they obsolete now? Pns: LOTAC05404 LOTAC05413 LOTAC05405 LOTAC05418
  19. First challenge is to create a signal from the cam position. I have searched the web for some examples but so far nothing found. Any thoughts on how and which parts to use to create a cam position sensor?
