Brett,

I echo the above question, what, if any, warranty is provided on the turbo conversion? Thanks.

>>>I echo the above question, what, if any, warranty is provided on the turbo conversion? Thanks.<<<

Well you can probably buy a separate warranty on your own as a separate expense. Or "self insure" by having some common sense and a cash reserve. You can get used 2ZZ motors pretty inexpensively. So some may wish to get one of those as a backup, or as the boost candidate.

Note also that there may be insurance issues to deal with too.

And a Unichip controller does not have OBD2...maybe the OE puter is still in use to help with things like that. In any event technically you cannot pass a proper emission inspection in many states. The car itself may pass smog tests but these days you need EOs, special inspections and so forth in many areas. Tricky stuff.

[ChrisStarrUSA]

Stan,

Good info. So how do people "get around" this stuff? I'm really interested in more power, and don't mind the money, or the lost warranty, or the occasional maintenance headaches. But to me, it must be streetable, and pass the usual emissions tests and other legal hurdles. I know lots' of people put turbos on things, so how do they manage to do this legally? Also, what kind of insurance issues?

Thanks in advance.

When Lingenfelter installed the supercharger on my Corvette, they offered a third party 3 year 36000 mile warranty from Dell Financial for $200.

Perhaps Something like that could be offered on this package as well.

Then if you look at the pinout diagram for the Elise cross reference it with a Celica (2000 would probably be best) make the necessary changes (in this case you may have to change all ecu wires over to toyota plugs) and pfc should work.

this would work. we just don't have an elise at our disposal or we woulda been workin on this already. lol

Turbo timers really aren't much needed for the more recent water cooled turbos - just don't shut the car off immediately after boosting... coasting into your driveway should be enough to keep the turbo happy - assuming you weren't caning it through your neighborhood.

That begs the question - is this a water cooled turbo? I haven't looked into turbos at all since my RX7 (after which I said I'd never own another turbo-charged car, but times have changed - maybe they are more reliable these days?).

[eliseowner2b]

Brian,
I wouldn't compare your Rx-7 turbo to others. I've had several modern day turbos and have a friend that sold his Rx-7 because that car was unusually complex (and expensive to maintain). You might know this already but that car had 36 vacuum lines! That means 72 ends that could come loose!

[BrettP]

Don't get me started about the RX-7. I used to work at an RX-7 specialist shop and I am a previous owner of the gorgeous car. Unfortunately there is a hand grenade under the hood!

[eliseowner2b]

It appears we have both bloodied our hands to the entertainment of that damn car! It took my friend 6 months of diagnosing/turbo rebuild/engine replaced only to find the first cat was plugged all along! He sold the car to his dad. It was totalled 2 weeks ago (sigh). (No one injured)

[Lotus F1]

The amount of failure modes on the RX7 is frieghtening. However it was a revolutionary light weight street legal race car.

great info thanx

You guys know that the Fed Elise is not the first Elise, which got an EVI- ECU. and that there are some experts in Europe who succeeded in remapping that other EVI?

I guess this can be done in the US, too.

Another point in this context:

Proper fuel / air mixture is very important for an internal combustion engine:

Too lean: You may burn the pistons. Too rich: You may burn the cat and together with it the whole car.

Therefore I would like to see the lambda value indicated! (You know you can buy wide band lambda sensors which are able to show you HOW lean or HOW rich you are running your engine and these sensors when can be connected to very nice digital indicator gauges.)

Another rather important value I would always like to see when driving a highly modified engine is the exhaust gas temperature:

And in that context I once wrote to Nick Adams:



>>>Hi Nick

Catalyst Overheat Tell Tale

In the Elise shop manual I read:

“This tell tale will glow red in the Stack if an engine fault occurs which results in the temperature of the catalytic converter rising to a level to cause damage to the converter and / or the engine.
Stop the vehicle in an area free of combustible materials and allow the converter to cool for several minutes before proceeding with caution.

The fault should be investigated without delay. “

After already some Elises caught fire I am interested in installing the Lotus Japan Only Catalyst Overheat Sensor A111E6062S or another instrument e. g. a pyrometer, which warns me as soon as critical temperatures are reached in the cat.

Nick do you know details about the above-mentioned sensor Lotus apparently has to install into cars shipped to Japan?

At which temperature does it switch on the tell tale in the Stack?

Is it possible to connect this sensor also to an aftermarket metal cat?


Or should I get a pyrometer e.g. as offered by Auto Meter (T indicated up to 1600° F = 871 ° C)?

Auto Meter’s WS is http://www.autometer.com

Cheers from Germany<<<<



Nick never replied. Perhaps at that time he was already too busy to get the Elise federalized for you guys over there.

No arguments here. When running right they are great!

Having owned one, I concur heartily with both points.

The troubles I had with the RX-7 are what make me want to hold back on doing anything too radical with the powertrain for the moment. A lot less to go wrong with normal aspiration.

Don't equate the unreliability of the rx-7 to pretty much any other turbocharged car. Turbo + rotary motor = boom. You don't get "oh I'm pinging a little bit, better add some fuel to the mixture." you just get BOOM. That coupled with the number of vacuum lines that the fact that mazda half-assed a number of engine components without thorough testing just to get it to consumers means timebomb. Quite unfortunate for such a beautiful and lightweight car. I wouldn't be a fraction as worried about ForceFed's turbo as I would about an Rx-7, and we will see about the reliability as his testing continues.

I don't doubt it - it's all about being gunshy on my part.

FWIW, my experience has more to do with an aftermarket single turbo conversion that I did on the RX-7, that took a while (and a new engine, and a second turbo) to fully sort out. The single turbo conversion greatly simplified the vacuum system; my problems had to do with final tuning.

Also, I never had any boost related problems with the stock motor.

The way I see it, I'll enjoy getting to the limits of the normally aspirated LSS car first, then look into upgrade options - and take advantage of the experience gained by kits like these in the mean time.

lol That's why I put an LS1 in my 3rd gen!

BTW, good work and I'm watching your progress closely. I'm debating on an Elise and I can't leave well enough alone. My wife says it's a sickness I have...

HAHAHAH! That is my next project car except with the new LS7 motor and perhaps a little 100 shot of giggle juice for the freeway "Supra" encounters!
