Here is an idea...

Except the engine brace/roll cage, the S4S is actually more similar to S300 than any other Esprit. Hethel incorporated into S4s many items straight from 300 development, with the exception of turbo which stepped back to .48 A/R turbine. S300 with its .63 A/R hot side showed loses of low end torque. Besides, it is possible to change specs on S4s to beat any S300 all day long. It just requires time, elbow grease and money.

As you know, I've been working on this concept for quite a while. Recently, I have made two prototype stub-shafts without the groove. Yep, that is the way to go and can be made! If you own a car with OEM Lotus limited slip differential and would like to upgrade to stronger shafts, please drop me a note at MrDangerUS at hotmail.com Depending on the demand, I may fabricate couple of extra parts for my Lotus Brothers.

Lotus owners who deposited $$$ down payment year ago, can claim their parts anytime. I will hold them for you. Also, I have a limited quantity for "open sale". PM me at [email protected] Cheers John

1995 Esprit I own, is the last S4s ever imported to USA.

Long awaited Super Strong Reverse Cut CWP-s for Citroen trans-axles have finally arrived. Parts were designed w/objective to maximize torque handling and Reliability. The best German spec Alloy Steel was used and a special heat treating process was used to maximize hardened layer (the "skin") on the parts. Compared to the OEM and HLM parts, they have more robust teeth with thicker roots and no stress raisers. Compare pictures 4 vs. 7 and 5 vs. 6. NEW DESIGN Pinion has 7 teeth and the Crown gear has 31. OEM 8/35 has a weaker pinion and crown gear, due to a smaller pi

Lovely project, Jacques!

It is new, it has a new diaphragm and used to come w/a couple of different springs, less blow by trough the stem bore. I'd take a used one, too. My stem had a large axial play. I have fixed mine by pressing a stainless sleeve into the housing bore and reaming it. Now it is v. tight. Never grind the stem, it is better to play with the housing.

Barry, here you'll find answers to your questions and a history of the development of this concept: https://www.lotustalk.com/threads/citroën-g-box-crown-wheel-and-pinion.350506/ Regards John

Steve, Where did you get the map for MJ? I'm installing MJ on my '88 turbo with Bosch CIS K-Jetronic injection and sooner or later will need to map it.

Bosch 002 pump is pretty weak (low pressure pump). If you necessarily want to stick w/Bosch brand, then use 010 pump. Price is not prohibitive Here is the performance diagram
