JRSC is fine as long as you make sure the belt is correctly aligned.
Have you checked the front of the engine to see if it has the light-weight crank?
It's been successfully campaigned for 5 years in club motorsport and tarmac rallies. Problem is it as about 4000kms away on the other side of Australia...

I'm getting it checked out at a mechanics and talking with the owner again

LOL - is there nothing nearer that you can make the same modifications to?

Where's the fun in that?

It's got good history, has been well built and is a very quick car at half the price others are going for.

I bought my current car over 1,000kms away. Nothing new to me.

hit up mx5nutz. Barry Spiers (legend) is selling a Mini Cooper Eaton setup for 700 quid. You need to supply engine management.

Gah. Why do these things always come along when I have no money?

What are people using for fueling and timing control?

Jackson racing uses a powercard that is fuel only. Is this enough on standard boost? Should timing control be used too?

Any recommendations?

Does anyone do a plug and play megasquirt for the 5?

From what I've read, most people believe that you can get away with 6 psi of boost, non-intercooled on the standard timing using super unleaded.

If you run higher boost, you'll either need to cool the charge or pull timing, or both and running a 99 RON fuel would be advisable.

I know the FFS 190 WHP kit runs around 10 psi and the Ecool system knocks off around 40*F of inlet temps and that is borderline for needing timing being pulled even on 99 RON.

As above the GReddy Emanage Blue looks ideal for controlling fuel and timing for reasonable money. People have also developed some very funky bits of kit to use with it too - including an "Autotune" box that will automatically adjust the engine's fueling to maintain 12.0 AFR on boost and at the same time remove "lean tip in" issues.

Www.diyautotune.com do pre built plug and play systems (£££) and diy plug and play systems (not so dear) using ms2. I'm currently reading through their book, it's very good.

Interesting, what is it about?

This book? http://www.diyautotune.com/catalog/performance-fue...

Would you recommend it for someone that knows the basics about how engine works but not enough to actually make any informed decisions? I'm thinking about 'charging my mx5 sometime too, but am almost at a loss for where to start other than reading random threads like this. Would like a book to read really. Is this the one or is there a better book/site to read?

There's a Portugese poster on Nutz currently running 200bhp with a Greddy turbo, Link ECU, bigger injectors etc etc. This is on a 90bhp late mk1 1.6. - For comparison I'm running circa 250bhp (15 psi of boost) on a 1990 1.6 with the same turbo.
I'm guessing this is on a standard engine, but have you needed anything like water / methanol injection to get 250BHP? I'm tempted to have mine remapped again with multiple maps for 8/12/15 PSI but would prefer not to destroy the engine in the process!

Absolutely. It's a very good read - starts from basics and then goes through the whole process of choosing what kit to buy, how to set it up and then tune it.

There's tonnes and tonnes of info on mx5nutz, miataturbo etc, but this is much easier to read and follow i'n book format.

I've spoke to the guys at diyautotune aswell and their super helpful. I'm planning on buying the diy-pnp kit for mine, and getting to grips with the tuning and setup etc - then it will be an easy job to add the boost hardware at a later date. Nit many people do it this way but they've agreed it makes a lot of sense. Bolting turbos on is easy, it's the electrons that make it work.

I reccomend the book.

Great, I might attempt to get that for christmas then smile I was thinking about doing it in that order too. Any reason you're choosing the DIY-PNP instead of the MSPNP for mx5s? Price?

Just in case you missed it, you know they're doing quite a healthy discount on those at the moment, but only for a couple of days - Thanksgiving.

This. But for what it’s worth I had an NA with a 1.8 with JRSC kit with a Motec ECU. Wasn’t that quick and could rarely get it running particularly well. Was ok but I doubt it’s worth the hassle, from my perspective.
