boosting my na6

[Greevn]

hey guys i have recently just picked up my stock as a rock 91 import na6 (second one), and took it for a good hills run the other night and it just doesnt have enough power for my liking, you have all probly heard this before but i am just wondering if there are any turbo kits that are any good . i will be removing the engine shortly and want to get cracking. so can any one help me out with any info.
i of course will be fitting forged h beam rods and pistons( unsure of what brand yet) jus wondering what options people have gone as in cams,injectors,manifolds,headgaket,ecu.
trying to do this as cheap but reliable as possible, hoping for around 180-210 rwkw

any help would be great
cheers greevn

Starting here is a build of a 200-250rwhp turbo setup on a budget, but fully track ready.

This isnt a how to guide, nor is it intended to be, but hopefully within, you can build a fully complete list of every little last piece of the puzzle for a reliable setup.

There are plenty of threads around regarding bottom end builds to suit the power levels you want to support, and id suggest a gt2560 for the power goal you have. Along with a nice tubular manifold.

Cool cheers, I havnt had much to do with the Mazda but I had a 20v 4age pulling 220rwkw with a hks 2515, do u think that turbo would suit as it made boost nice and quick ?

[NitroDann]

Is there a manifold/dump setup available for that turbo?

Dann

Yea it's a skyline flange which is also t3 I think or maybe t4

[NitroDann]

Ok if you have the turbo, and can get all the lines to fit, and a matching intake exhaust and downpipe along wirth a manifold go for it, it would probably suit very well.

Assuming you want to continue to be able to safely and legally drive the car on the road - you really need to be talking to someone with experience in building realiable engines for these things AND getting them through the appropriate testing - for you I beleive that will be regency?

bark on here has been there and done that (Regency for a turbo MX5), and if I recall correctly had a few hurdles along the way. He's there now, but it wasn't a simple road, in another thread he spoke to someone else looking at a similar thing and said:

In regards to engineering, investigate the requirements upfront and budget for it, else you may be left out of pocket and a car that can't be registered in SA...

Awesome advice! I once wrote a thread about doing it properly in NSW, however it's not going to help you very much these days, or in your state.

As for an 180-220rwkw... It's not super easy, well, 200ish is reasonably simple, but much over that and you'll run into a bunch of bottlenecks - I'd be surprised if there were more than 5 turbo 1.6 MX5s on Australian streets that were making over 220rwkw day in day out - Lots right around 200, and lots of 1.8s making well over 200, but like I said, genuine street legal, street dríven, very few.

All of that said, 160rwkw in a nicely balanced early MX5 is more than enough for crazy amounts of fun. I'd say try and get into a couple of turbo MX5s before you decide on an outright power figure anyhow, I mean 180-220 is a 40kw difference, more than 20%! 180 is pretty straight forward and reasonably cheap, chase much more than 200 and you'll start spending big money for minimal gains.

Hi

I recently fitted a FFS supercharger
10psi and 170rwhp
adjustable coilover suspension
whiteline swaybar
Toyo R888 tyres
has taken 6 seconds off my usual track time, SO happy with the guys at FFS so helpfull and I only have to change the crank pulley to take it up to 16psi and 260rwhp ... But not going to do that as it is awesome as it is. The FFS kit came with everything, fuel and timing cards are pre tuned nothing to buy whatsoever it's all in the kit (unlike some kits ) it's very smooth from idle up to rev limiter 7500 rpm I'm no mechanic but fitted it myself in a weekend, just bolt it on plug it in and go the difference is amazing .. cost $4000 worth every cent
