All, just a quick update on the progress of my turbo project...

I have it booked in Monday to have the MSPNP tuned. I have found a tuner in Adelaide whom actually tunes according to the combustion in the cylinders rather than with an AFR to ensure that I will pass the IM240 test at Regency Park. According to the tuner you can have an acceptable AFR but if the chemical mix is wrong then I'll fail the IM240 test, something I was not previously aware of!

I had taken the car to a different tuner but they weren't up to the task. Car is running ok on a very basic map that MS has generated by me adding in just a few constants such as injector size, cc of the engine, etc... It runs ok up to about 3,500 to 4,000rpm anything over this and the engine begins to cough, splurt and carry on.

Once the car is tuned I'll post a bit of a write up as well as some pic's to share my learnings with you all.

fingers crossed

Do a few logs and tune using analyze in megalogviewer, you will get a pretty decent tune on it so its doesn't cough and carry on until you get it tuned.

Now why did i think it was impossible to attach a turbo id SA?????

I was seriously under the impression it was next to impossible or even illegal.


can you enlighten me?

or was it because a few years back a member made such a fuss that I thought it was impossible.

not impossible.....just lengthy and expensive with no guarantees.

I submitted an application listing my mod's and spoke to them on the phone re what I planned to do. At the end of the day as long as the vehicle passes an IM240 test it is legal... So now I have an approved application to modify which has just been extended another 12 months.

Once tuned I will be taking it down to get passed on the IM240.

I don't think it has been too much of an expensive exercise. The tune is going to cost me somewhere between $500 to $2,000 which includes an RG240 test (which is $500 alone, but once the vehicle passes this it will pass the IM240). The RG240 test is the same test (an IM240) that Regency will require in order to pass the vehicle. The only difference in the two tests is that the regency equipment is certified and the RG240 test equipment isn't certified.

legal turbo conversion in adelaide? i'll believe when i see it. keep up the work though

gosh, looks like i'll be the underdog of the Adelaide drivers here for quite some time...

I was wondering what had happened to this project bark, i remember getting a few PMs and posts regarding your project ages ago!
good to see its still happening!!

When i was going through the rigmoral regency told me an engineers report was a must also as well as emissions testing, and said i had to use one of the engineers off their list.

You heard anything like that bark?

L.

Luke, no engineers report required. They stipulated that I had to upgrade my brakes (to the later model ones) which I have done and as long as I pass emissions its a done deal (so I'm led to believe).

It has been a 12 month project, the longest part was collecting all of the necessary bits but this was hamstrung somewhat by the bank balance!

Anyone know of who owns a black turbo'd NA6/8 in Adelaide? I saw/heard one some 4-5 months ago...

Keep the posts coming Bark. I too am very interested in getting Adelaide's requirements straight.

Ok latest update - 18/4/08

Since my last post I blew the top tank of my radiator (plastic had fractures which blew) and I have added a sard rising rate regulator.

In order to be able to tune for emissions I have had to re-install my std 230cc injectors as well as my standard fuel regulator. I dropped in today and the car is just about setup for a cold start to meet emissions.

Next step after finalising the cold start will be get the emissions right for a warm engine...

Once cold and warm maps are set I'll be taking the car to regency to pass. Once passed I will return the car to the dyno, re-install larger injectors and rising rate reg and the have it tuned for power. I will need to purchase a larger fuel pump.

For those of you who wish to build a turbo engine from an NA be prepared to pay for tuning time - an emission tune will cost from $1,500 to $2,500 plus regency fee of $495. This is no cheap exercise, I am now committed and want to see this through.

I would have been better off buying a std turbo car and tweaking that, however I lurve my little mx5 - I just underestimated the expense involved as well as the time to meet emissions.

glad it's you doing all this work, not me

Thanks for the update. Who in Adelaide is doing all the emissions tuning for you Bark?

Cheers

Bell's Automotive (located Main North Rd, Blair Athol) is doing the emissions tuning for me. Stephen came recommended from Regency and he has the 'know how' as well as the equipment - he is very knowledgeable re emissions.

Just refresh my memory again please - is this a \"kit\" turbo or have you put the components together?
