GReddy Turbo Kit

[meanmx]

I'm looking at around $1800 landed for the greddy kit whereas the avo one is around $4000 I think. I'd prefer the avo as well!

Why dont you just save your money for a AVO kit Ben??

Ok now I am really confused. Having a look at the AVO website I suppose I could just afford their torbo kit but is it worth it. I would be looking at double the cost and a harder installation. Considering I only want at the most 150rwkw at some stage in the far far future, wouldn't the greddy kit be able to handle this with sufficient upgrades? Does the extra benefit of a ball bearing turbo really make that much of a difference with spool up times? Even adding in $500 to install an intercooler which will take the greddy kit up to $2300, it is still a crap load cheaper than the AVO. Can anyone justify it to me for clarifications sake.

There will be compromises with both kits.
Don't get me wrong. Both kits are good. I would sway in favour of the AVO kit if $$ allowed it.

Purely for the simple fact of the quality of the castings in the manifolds.
It is well spoken of on www.miataturbo.net (have you checked it out yet?) that the Greddy manifolds crack over time, to reduce the chance of this relief cuts should be made on the manifold. The Greddy dump pipe is a little restrictive and you will be running 12psi to reach 150Kw.

Now the avo manifold flows quite well and although looking quite bulky, has a lot of strength in its casting. Be preparred to call it all sorts of names when you put it in though the us guys are rating it as flowing better than castings up their way (not to mention better than some tubular manis).

The avo dump pipe is a solid unit too. Less restrictive than the Greddy and you could probably reach your Kw mark around 9-10psi.

There are 2 main differences between kits as well. Greddy is a top mount mani. AVO is side mount which mounts the turbo lower, keeping a lot of heat away from your bonnet (which could cause paint burn). A lower mounted turbo will be easier to fabricate piping for (be it intercoolers, dump pipes, etc)

Hopefully this doesn't sound too biased. I have a Greddy mani after all, but i must admit the AVO quality is a lot better.

BB turbos spool up faster, but the mx is light enough where lag is not a problem.

You will have more than a little bit of difficulty getting a Greddy kit to push 150 KWatw... If that is your aim, spend now, not later. If that is your aim, get the computer, injectors, diff, clutch and brakes done before you spend the 4K.

Just my 2c, that's what I would do, and I have experience behind that decision.

What he said!

My clutch is the weak link atm, even at only 6psi it hates me.

Sounds like this is gonna cost you heaps Ben, your better off just buying a NA8 and turbocharging that. It already has better brakes, stronger diff, bigger engine and a working electric aerial.

I would go with the AVO kit though, its like anything you get what you pay for. But I would also start with a NA8 platform, saves having to upgrade everything on an NA6.

DONT BUY A GREDDY KIT!!!!
ok so the gReddy might be 1800 but then you still need oil lines/ Dump pipe/intercooler/IC piping/ engine management/better studs and bolts as the greddy ones suck.Youll end up spending the cost of an AVO on it anyway.

MOST of the stuff that comes with the greddy kit is crap and you have to replace it anyway, leaving you with the turbo and manifold and a very crappy downpipe.....

I'd suggest buying an AVO /manifold/down pipe and work from there....Use a second hand turbo to save some dosh..youll still have to buy all the extras that you would have had to buy anyway with the greddy kit and youll have a much better solution..

just my 2 cents

My complete turbo set up will most likely be for sale in a month or so.
It runs the AVO exhaust manifold, 320hp GT25, FMIC, EMS dualsport, and 370cc injectors. Wiring loom, intake, the whole package.
So basically everything you need except the fuel pump to make ~160rwkw on 15psi on a standard 1.8.
pm me with EOI.

and dude, don't tempt me......

See here for my EPA story, wont go to OT here http://www.aus-cartalk.com/viewtopic.php?t=26345

FFG,
Looks like I may have a taker on the turbo set up already. If you want temptation though mate, come around for a ride before the epa suspends the reg. If the other guy fall through, which I think will happen, it would be great on your car.
Got a spare gearbox I can sell you too, you'll need it.

Alright guys, I have given this much thought and have been looking at all my options. I have basically discarded the idea of the greddy kit thanks to the words of wisdom from members of this forum. I tossed up the idea of the Jackson Racing supercharger for a while but decided against it because it has the MP45 supercharger instead of the MP62 supercharger which seems like the better option. So I come back to the AVO kit. Unfortunately it is very hard to get a straight answer from them regarding price. I have had $4000 up to $4600 with $1400 installation. Now the question is should I get it installed by them to get the epa certification or should I save my money and install it myself or get the \"no electrics\" kit and spend the money I save on upgraded management system? I know the epa certification would be nice but what are the chances of being pulled over if I am not overtly demonstrating the fact I have a turbo? I know several people in Victoria have done turbo conversions. How have they dealt with this predicament?

In your shoes; I would get the AVO installed by them wth EPA slip. Drive away and enjoy the benifits while saving for full ECU and injectors install. After that, keep EPA slip and stay away from the boys in blue.

Man I love QLD!

EPA certification is your get out of jail free (well you pay extra for it ) card.

This card also brings along the benefit of a registerable and insured vehicle.

I would hate to be talking with you in 10 years time, with the topic of the story being...
\"Yeah i was driving my turbo mx5 and hit a Merc. Insurance was voided because the kit wasn't certified and now after I pay my monthly legal bill, i get to snack on rice cakes\"

It is great to have boost, but do it properly as the consequences of not doing so can be very costly. Speak to an engineer, see what he would recommend on passing your vehicle down there.
Add that up to the no electrics kit (he may be comfortable if you use his tuner and a MSPNP), if you stay cheaper go that way, if the AVO installed version is cheaper then that is the case.

There is a reason the boosted path is not often travelled in mx5s.
