Benoit,

Did you manage to get in touch with Janspeed?

You have asked about the Janspeed turbo conversion on here a few times now, and it makes me wonder how far you actually got with Janspeed.

Its no use trying to e-mail them - I don't think you will get any response. As far as I know, they do not have an e-mail address that is for the use of the general public. I think I advised you to try contacting them either by telephone ( if you feel confident enough about your spoken your English ) or by letter. I think if you tell them about your car, and you quote the conversion number ( from the Janspeed plate in the engine bay ) then I think they might be able to help you.

However, this is something that they sold MANY years ago - so you will have to talk to the right person inside the company. Most of the younger staff will probably have no idea what you are talking about. This conversion was made before many of the technicians there were born!

Failing that, I can try to get the information that you need from them on your behalf. I'm willing to give it a try if you tell me what you need to know. You need to be specific about your problems and you have to be sure that you are not blaming other more basic spark and fuel problems on the Janspeed parts. Also, how do you know that the turbine itself is still in good condition after so long being unused?

If its a Micro Dynamics control unit, then what do you need to know? Again - it might be a good idea to try contacting them direct. You will at least need to try to identify the part that you are enquiring about. Does it have a design or model number on the unit?

Thanks Alan,

Yesterday after trying several times to contact Janspeed by mail ( 1 answer was gives to me by a woman "Becky" about the timing advance and the spark plug type, but the other times when I ask more precision about the kit I have no answers)

I decide to contact them by phone and ask Becky, I have someone but unfortunately my English speaking is not good enough to understand all what she say and probably my explanation wasn't very clear....) must I take more English lesson....

It's impressive like the English speak quickly at phone!!!!

But she gives me an e-mail address for someone that could answer to me, so I send him (Matthew) my different problem and needs; I hope he could answer me....

My question in the forum was also to know if someone still has this kit on his car or if the reliability wasn't good enough to keep it on the car. Also I suppose that someone that have cover several thousand of kilometers with this kit can tell me the different problem he had meet and the solutions.

About the turbo I think it is in enough good condition to boost to the 5 psi, I have already cover 200 kms with the car and my first problem was to adjust rightly the S.U (without specific tools), so some time the engine run pretty good and sometime badly, but know the tuning was done (with the help of color tune sparkplug tool), but after cleaning my carby I know he need servicing.

When I have check the timing advance I 've find 27° BTDC at 750 rpm, and Becky's at Janspeed tell me to put 8 deg BTDC at 750 rpm, and know the car run badly and have backfire to the carburetor when I accelerate up to 3500 rpm (my carby was be tuning again, my valves clearance checking, the compression seems to be good enough to a 2.6L (8 to 8.5 bars for all cylinders), I have the right spark plugs and spark plugs gap, the timing point were check too and I have done an ignition test (right to all the cylinders) the only curious thing I find is the dwells % that is very high (96%) when the micro dynamics controller is on the ON position and only 55% on the EMERGENCY position?????!!!!

Why??? I don't know....

Sometime the engine stall when I am on the ON position and when I put to emergency the Engine restarts (another problem...)

The micro dynamics controller (turbo controller unit type EMS 3) (turbo dynamics phone "0883 49281") have an timing advance adjusting screw but I don't know if it's to adjust the pressure depression timing or rpm timing or static timing) I think it's probably the first but how to tune?

Well like you can see several question, because I have nothing about this kit and find little by little.

Know I wait for Janspeed answer...

(conversion number 2989)

Thanks

So someone have one of this kit on his Z?

Hi Ben,

Seems that you have had fairly good contact with JANSPEED already.

Its very difficult to troubleshoot your problems online. However, as the engine actually starts and runs I'd have to say that you are now going to need to get into the fine tuning of it. It seems to me that the problems can't be that big, and must simply be a case of adjustment to spark timing and mixture. Everything else is just going to be common sense..............

The Janspeed turbo conversion was actually a very simple and trouble-free setup as far as I have heard. There are still a few cars with this conversion being used regularly here in the UK. I'm sorry I don't have any direct contact details for any of these people, however I'm going to send a PM to you with information on the UK "Z Club" where you MIGHT be able to get in contact with a UK-based Janspeed turbo conversion owner. At least you might be able to get some accurate first-hand advice.

Good luck,

Alan T.

Thanks for your help Alan, like you say, i think too, that is not big problem, but rather several small problems, as my carburetor seems to be well tune (according to the colortune sparkplugs tool), but i soon order a service kit for it; i think it's more the ignition that need tuning i suppose that my pressure drepressure timing is involved or the pressure depressure sensor that give the information. Perhaps that someone before had tune the car for the best running and find it on 27° timing advance because of the pressure/depressure advance faillure!!!

so i prefer had more information before doing a mistake.

thanks one more time
