Lotus Turbo Esprit Fact Respository for the 1981-1987 Lotus Turbo Esprit (the Giugiaro cars.)

Custom Lotus parts, guides and facts for the Lotus Turbo Esprit. 2.2 Liter Lotus engine with turbo. Guides for tires, wheels, engine, transmission as well as custom carbon fiber, aluminum and fiberglass parts for the Lotus Turbo Esprit. As well as an adjustable suspension for the front of the car.

Facts for both the US and UK Lotus Turbo Esprit, including spring rates, engine info, parts, modifications, specifications (specs), pictures, users, owners and vital information for the Lotus.

Some information might be valid for non turbo cars and other Esprits as well, some custom parts may be usable on non turbo version of the car and other parts may work on the later Esprits. And suspension adjustment and springs, coilovers coil overs and other stuff.

Turbo Esprits have the 2.2 liter lotus engine and 210 horsepower, we have custom fiberglass, aluminum and carbon fiber parts being developed along with a multitude of facts on the lotus cars.

We will have replacement OEM parts as well as custom unique parts for the esprits made from fiberglass, carbon fiber and aluminum.

We are interested in hearing from other lotus owners including S1 owners, S2 esprit owners and S3 n/a lotuses. We have a variety of owners.

After the failure of the K&N I ran to the closest auto parts store and bought another filter. I referenced the catalog (under "Lotus: All Esprit",) and bought this filter. Getting home I realized (after trying to fit the filter) that the filter is too long for the space. The end of the filter doesn't clear the starter. Not to mention after some research, the NAPA filters aren't that good and it also doesn't have a pressure relief valve like the stock Lotus filter.

Additional Information: I've done some research on Oils lately and discovered an interesting fact about oils labelled "Racing Oil". There's a very good reason that Lotus recommends Racing Oils that you all should be aware of. Evidently, older oil formulations included substantial quantities of what are called "anti-scuff" additives, which helped significantly reduce valve and rocker ware in non roller-rocker cars (like ours). These anti-scuff additives (primarily Zinc and some other metalic substances) were deemed "unfriendly" to the environment and as such were almost entirely eliminated in automotive oils some years ago. Many long-time mechanics that I know, confirm a noticable increase in rocker-area ware since this change was made as a direct reslut of the formulation change. The good news is, all these anti-scuff additives still exist in the proper quantities in Truck Oils (like Rotella) and in anything properly labelled as a Racing Oil (like the Lotus recommended Valvoline 20/50 Racing Oil). Just thought you'd want to know.

I bought (and have used) the oil extractor from Griot's. A clever idea that just doesn't work on our cars (the dipstick doesn't go far enough down into the oil pan.) I will want to re-test this to double check that it can't remove all the oil via the dipstick. The oil extractor can come in handy for other tasks though (whenever you might need to vacuum oil into a catch tank).

As you may (or may not) have noticed the oil filter on the Esprit is in a horrible position. The consensus is to remove/install it "from the top" not from under the car. Be aware that the coil is nearby as well as a couple vacuum lines (among other things.) It is fairly easy to pop off electrical connections and vacuum connections (thus preventing your car from starting or running properly.)

Mobil 1 Synthetic oil is very good oil, but on older engines you may see seeping with synthetic. Part of the reason is because Synthetic oils are generally a thinner consistency for a given SAE rating. You may want to switch to a blended oil or organic oil if you see slight oil leaks from your Esprit.

to:
Mobil 1 is one of the better store bought synthetic oils you can buy (you can pick it up from almost any store.) If you wish to go above and beyond Mobil 1, the two popular choices are Red Line and AMSOIL. Red Line can be bought at some auto parts stores (like Advance) or through mail order from Jegs or Summit Racing. AMSOIL is only sold through AMSOIL dealers (there are a variety that sell online.)

According to AMSOIL's independent tests it is apparently the better oil, however recent tests did not include Red Line as part of the testing. In addition the fact that AMSOIL is not sold through regular channels seems to be a practice that doesn't inspire confidence.

Changed line 5 from:
The two main things you need to look at even if the book/computer/whatever says that a filter should fit is the length of the filter and how close the threads of the filter are recessed into the filter.
to:
There are multiple suggestions as to what filters to use on the S3/TE, some of this information is incorrect. Some filters that may fit earlier/later cars will not fit the 3rd generation cars. The information presented here is based on the design/layout of the carbureted engines and the EFI cars may be different.
Changed line 7 from:
The Lotus filter has a raised part that brings the threads very close to the height of the gasket, compare that to the K&N which recesses the threads so far that you can't screw it into place (the threads don't touch.)
to:

Choosing a Filter

Changed lines 9-11 from:
The length is very important, the ignition coil sits in a location behind the filter that prevents a tall filter from being used (i.e. NAPA.)

Also the stock Lotus filter has a pressure relief valve (you can see it through the threaded hole at the end of the filter, some filters don't have this (and I don't know how important that is.)

First let me say that the parts catalog for a particular brand can't always be trusted. I bought three different branded filters before I found one that fit.

K&N HP-2004 Although the K&N is one of the best filters you can buy, the suggested HP-2004 just doesn't fit our car.

NAPA filters (as recommended in their book)

I don't know how good the NAPA filter is, but after figuring out why the K&N wouldn't fit in the car I ran to the closest auto parts store and bought the filter as suggested in the book. Getting home I realized (after trying to fit the filter) that the filter is too long for the space. It is possible if you remove the coil you can fit the filter (then fitting the coil back in place,) but that's more work than it's worth in my opinion.
