Adaptronic is an unusual choice these days. Have you seen the MS3 Basic that Reverent is building?

See comparison chart here.

See discussion thread here.

If I was in the market for an ECU it would be difficult to choose differently at present. You must be in Australia to choose otherwise. There is no location in your profile under your screen name.

You have neglected the harmonic balancer upgrade which becomes very important at higher horsepower values. Harmonic Balancer Miata

the adaptronic is due to my location i am afraid of my preferred tuner not knowing how to use ms3 cause i know that is a preference on here

other things i am happy with adaptronic is the easy flex fuel feature
the bad things like no dual boost maps are a bit of a detractor not to mention
the $1700 price tag here in australia

the balancer i not payed attention to cause i see so many that do not do it they just do the boundry oil pump i will have to do further reaserch on this thank you

its never cheap is it

Nope. Building performance cars has a way of getting your money out of you upfront (buy expensive quality components first), or later (buy cheap stuff, watch it break, then buy the expensive components anyways).

Good luck with the build, get a thread going in the build section if you get a chance.

mx5psi

My intention is to make a proper build thread when i have all the parts

Does anyone know the record for an AVO kit ?

nitrodann

You are aussie right?

Im from newcastle, Ive done 297whp on a 1,6L.

Good luck on your build. Looks like it should be fairly well sorted.

Whatever you do, DO NOT dyno on the retarded POS that Dann used. Its pretty much useless and no one believes its numbers or consistency.

Try to find a dynojet or something consistent.

mx5psi

Is this with the avo cast dump pipe?
And what engine managment did you use?

Im from victoria there are not too many turbo mx5's here
Silly thing is i prefer driving my relatily stock NB even over
My 412rwk v8 i cant wait till its turbo charged the ford will never leave the garage lol

Anyone else

nitrodann

18psi is mad cos i built a new manifold and exhaust and pulled 325whp with the 2560, which everyone said was impossible and couoldnt be done, even with E85. they were wrong.

Dann

mx5psi

Wow 325rwhp sounds massive for a t25 on a 1.6 what pressure is that up too ?

nitrodann

All of it.

22-24psi.

Does anyone have any feedback before i order alot of theese parts?

Basically your engine plans look solid IMO.
Your choice of turbo is good too.

I'm just kinda iffy about the AVO setup vs something much more efficient available through our fabricators

Not a lot of people use the avo stuff. Most of it is either fm/begi or custom. There are a bunch of greddy kits floating around but they are getting more and more sparse.

You're such a jackass. Go read the thread. People said you wouldn't hit 340-350 or something along those lines not 325. Even with your suspicious dyno you still didn't do anything we didn't already know. e85 is good for some extra mid range tq and a couple % up top.

last time i checked 325 is not 350 even on some shady dyno.

mx5psi

I priced up a fm kit here for australia normal kit cost plus all the extras i wanted and getting it to here was heading over 7,000aud which was too much

And i do remember reaserching a gt2871 on a fm log you do need to knotch the rail whick is a big no no here in australia

Another reasons for choosing an avo cast over a fabricated one that it has that semi stock look its a full kit that works i can replace the bits that wont suit my goals ie that restrictive dump pipe and the cast inlet also reliability come into consideration

Another thing i have read on here a member replaced his AVO log manifold with a begi one and lost spool which i didnt give a crap about but it has recently become a factor for drivability reasons

As for Dan he might very well have those figures but a 1/4 mile run is the way to see if he uses a "happy dyno"
Sounds wierd i prefer a low reading dyno it feels more realistic i always quote the lower for my nugget ford even though it has read higher

With the boosted 1.8 guys have you had any benigit from cams at all ?

My engine builder thinks its the only thing im missing

18psi

iTrader: (76)

There is talk of cams for 1.8, but not a whole lot of it. Apparently some company in UK is making some, but no one has posted results yet.

nitrodann

To OP.

You wont get anything better than the standard dump pipe, its location is the problem, and the design reflects this.

Dann

mx5psi

Wrong i have devised a clever way to fit a 3" dump its going to be amazing

nitrodann

Lol, turbo adaptor that rotates the turbo so the rear faces downward, cutting the shelf ?

What?

Dann

mx5psi

You will see its way too simple cannot believe it has not been done before actually i know its been done before im refining it
