  1. Not sure of a specific place in Chicago area, but will echo the comments about this being something any shop could handle. Nothing complicated, just lots of hose unions each with a clamp that likely needs tightened. A pressure tester is a great tool for any Esprit owner to have. The pre-trip pressure test saved me from roadside disaster more than once with my V8. I will say that in 10 years of ownership, the primary reliability issues were coolant leaks. The only other issue was a failed alternator, but I still made it home. Upgrading to the silicone hoses from JAE is highly recommended. For now though, a pressure tester and some time under the car tightening hose clamps will have you sorted. Not the ideal weather for repairs, so whoever you trust for your daily driver can tackle this too. A lift makes it a quick and painless effort. Regards, Rod Cleveland Oh
  2. Many thanks. Was hard to let go of. I am certain I will regret it, but it was time to move on. It is headed to Lancashire. Maybe you will cross paths with it at an event someday. Regards, Rod
  3. I sold my modded Esprit V8. It is headed back to the UK. I never got around to installing the G50 conversion that I bought from Mike Seekinger out of John (Jack?) Hazzard's Esprit V8 race car. These transmissions (G50/52) seem to fetch a fair amount of money from the mid engine kit car guys due to the fact that they can be made to handle 800+ hp. I have the trans listed on eBay. I did want to post some pics of the conversion kits for the Lotus community in case anyone is curious to see how this could be done. The parts were rather crudely executed so I planned to use them as templates for my install. The axles and flywheel were nice, so I suppose the rest is cosmetic. I never personally ran this setup, or saw it in a car. But I do know that it worked. Anyway, a bunch of photos are included below.

  4. Somehow I missed that spec in the workshop manual. Thanks much for providing it! The turbo indeed stopped smoking with a quart less oil, but now I can ensure that the dipstick is providing a correct reading. Regards, Rod
  5. Ok, I know this sounds remedial, but bear with me: I know the book says 6.7 quarts for an oil + filter change, but does this account for the amount of oil you may or may not drain from the coolers?? You might ask, why not use the dipstick er...dipstick? Well, because mine has been replaced and I am not 100% sure that the new collar and nut are in exactly the same spot as original. They are not a fixed length, but instead a pipe and compression fitting. This is a basic error to not be sure, but before you judge me, please note that Lotus never intended this part to be replaced with the engine in the car. Why the big deal? Well, I am pretty sure I have been over filling it because my freshly rebuilt (for the second time) turbo charger (RH side) is smoking again after I topped off the oil and went for a few hundred miles of aggressive driving. Before the second rebuild, the turbo would stop smoking if the oil was low, but I rebuilt it anyway. I had added a quart based on my dipstick reading (bottom marker) and it read to the top marker (as expected) when cold. After the drive, the reading was nearly 1/4 inch above top marker. There was no fuel or water in the oil to account for this increase in level. I drained the sump and thoroughly collected the oil from the filter (always cut them open for piece of mind, or warning signs). Tallied the total oil and it was almost exactly 7.0 US quarts. Cold. Sounds a bit high, but the arse-high attitude of the car when I drained it makes me think my coolers are still full. So if the book figure includes oil for the coolers, then my 7.0 quarts + cooler oil is certainly enough to prevent proper draining of a turbo and probably a bit of oil frothing in the crank case. If 6.7 does not include coolers, then the extra 0.3 of a quart does not sound like enough to explain the turbo smoke. Which would be highly unfortunate news. Incidentally, I put 5 quarts in and the dipstick reads 1/8 inch above low. Cold. This is after letting the car idle for 20 minutes the prior day with no smoke whatsoever from the turbo. I did drop the exhaust and clean out any residual oil in the pipe and turbine housing. Thoughts? Thanks in advance!
  6. After switching to the Red Race ECU on my car I had all sorts of idle issues. I am told the original mapping for learning idle was crude. (Perhaps since it was an early tune for racing and did not benefit from improvements along the way.) Anyway, I also replaced the idle valve a couple times. In fairness I had a crack in the EGR tube that I think was shortening the live of the valve through allowing excessive heat to build up under the plenum. I tried all the other options as well: clearing the memory and 'retraining idle' replacing temperature switches. Monitored duty cycle on my laptop etc etc... Stalling is very embarrassing. Theoretically, the cars should idle with the idle valve fully closed. Finally, I just went for the 'cheater' option and made a slight adjustment to that little set screw on the throttle body. This can be done without taking anything apart, but it is tricky to get at the jamnut and fit the right screwdriver. About 3/4 turns and the car has never stalled since. Basically, I needed the car to be able to run at a minimum of 650 rpm when the ECU has the idle valve fully closed. It is a cheater fix, but it worked. Regards, Rod Wiggins
  7. Matte clear would be a great way to get the same effect on another color. Might be even cooler than on black even. Loved the Land Rover picture. It was made even better by the branch scratches that should be required by law on any proper Defender.
  8. I have seen the effect in a couple of instances and thought it was very cool and somewhat subtle. Here are a couple pics of my matte black stripes on my Esprit. It was a real pain to get them to follow the lines of the car and still look straight from front to back. It is really hard to capture the effect on camera. It looks much better in person. Let me know what you think.... Also, I did change the color of the wheels a touch--trying for a subtle gold. It just looks like I have a bit of filter on the camera in these photos. Here are a few more photos. I actually did the bumper a second time since these were taken as the stripe was not quite straight. Regards,
  9. IAC valve is a constant headache for me. High heat can cause them to stick closed or open. I would find that taps with a mallet on my plenum would slowly unstick the IAC and return it to normal. Not practical at stoplights. Likely time for a replacement. Alternately, you could have a significant intake leak on that bank which would explain the high idle and the lean mixture (hot exhaust). Spraying a bit of carb cleaner at the edges of the plenum while it is idling high is a good test to find a bad gasket. This is a long-shot. Just the only thing that would tie the two symptoms together. More likely is the failed cat. High engine bay temps may have shortened the life of the IAC but it is time for a new one anyway. When you have the plenum off you can inspect the gaskets. The cat issue should be easy to confirm. The difference in heat for the collapsed cat will be obvious to your hand from a few inches. I believe the exhausts are linked, so you wont be able to tell much from the relative flow out of the pipes. Pretty much I am agreeing with what the others have said. Regards,
  10. I had Johan's setup prior to the factory red. I must say Johan's felt a bit better for low-end torque and throttle response. A/F ratios are very similar at full boost. I thought that Johan had copied the factory map, so I may have been imagining the additional 'snappiness' in his chip. I did not do any dyno comparison. I had fried my Johan-modded ecu when I charged the battery and needed a new ECM anyway. Decided to just buy the factory red and be done with it. It was only a few dollars more. Thanks for all the feedback on the EGR question. Can't wait to remove the whole lot! From the manifold on out. I have to wonder what sort of EGR flow the red ECU was actually managing through the EGR stepper motor on a US-spec car. I have to imaging EGR flow along with hot exhaust gasses under the plenum contributed significantly to the sticky IAC valve. It always stopped working after a hard pass. Regards,
  11. Anyone know if the EGR functions are fully disabled when using the RED ECU? Asked another way, anyone using a RED ECM that does not have EGR at all? I have a US-spec 98 Esprit. I am using the factory RED ECU. I have the plenum off to replace a sticky Idle valve and I noticed that the EGR pipe is cracked. This may be associated with the reason the my last IAC valve annoyingly only lasted a year. I would really like to remove the EGR system altogether. I understand that the early UK cars did not have EGR at all and the non-US cars show a small plug inserted in the EGR manifold that would appear to effectively disable the system. My concern is that I do not want to end up throwing a code if I remove the EGR pipe and plug both ports. I assume the 'race only' and non US-specific nature of the Red ECM would dispense with such things as EGR in the same way it ignores the post-cat O2 sensors. Can anyone confirm this? Many thanks!
  12. Nope. I am packing the Esprit up right now for the 5 hour trip. See you there!
