NA6 requirement

[StanTheMan]

Hypothetically

max power no more than 160 rwkw. I just don't want any more than that. somewhere aeound 130 or 140 would be my sweetspot.
little lag as possible none if possible
OEM respones for city driving
small budget.
Not going to race this.
probably will never be dríven in anger.

probably will never happen. stil have to paint it first.

thoughts.
ebay kits ?
what turbo?
is there a thread for beginners? Tuboing for dummies?

Piggy back is fine. Don't want to go down the tuning side of things. Been there before . It ended in tears.
Ive read ND's thred on a turbo for $2k....couln;t find a dyno graph. 50% more so we are talking about 90-95 rw kw?

[StanTheMan]

currently the car has a NA8 driveline including brakes
torsen
2.25" excsaust...I think?

an agry allignment

[NitroDann]

Indy So of IS Motor Racing, who did the final dyno told me 105rwkw. The car itself is currently for sale, in the for sale thread it claims 95rwkw.

Also, its 2014, please dont piggyback, the driveability, fuel economy, power, the safety net a real ecu provides.. Well it almost goes without saying.

I have an NA6 here which has an AVO kit, including the piggy back, and on 10psi it was BARELY faster than an intake/exhaust/compression, stock internals NA6.

Now with a proper ecu, a new exhaust, and a couple of small extras (throttle position sensor, boost control valve) it now makes 265rwhp. Its an unopened 89 model na6.

50% more power and lag free is easy.

[StanTheMan]

most important to me is OEM drivability.
265rwkw would scare the living daylights out of me. so 130-140 would be the sweetspot for me.

edit just realised I'm takling killer wasps and youre talking horses....200 would still be way too much for me.

[NitroDann]

Thats HP.

If you want the simplest way without changing driveability at all... It saddens me to say that the answer is probably a very basic kit with a rising rate fuel pressure reg, also known as a Fuel Management Unit.

Like this one.

That with some accessories.

But its not a lot cheaper than what I provide for the dollars, and with a FMU it wont perform spectacularly at all.,

I think Dan's talking the old language.
265rwhp is about 200rwkw.
Still a lot, but less boost will give you less power so it wouldn't be hard to bring it down to your level.

I've had chats with Dann about this.
I was looking for a cheap cheap kit for a friends car.
But wanted reliability as he does track it.

Either do it right the first time (Dann has done this many times and what he says you need is what you need)
You skimp on certain bolts or fastners to save a few bucks and you will eventually have to replace sh*t.

Megasquirt is pretty cheap ECU option.
Nissan Silvia/200sx/180sx turbos are cheap and good option
WRX/Forester turbos are also cheap and work well.

Injectors - Dann mentioned some.. Can't remember if they were RX7 or 8 injectors. - cheap and work well.

The rest - manifold, dump pipe, studs/bolts etc as per Dann will suggest.

If you haven't already seen it, youtube mightycarmods and find their turbo mx5 series.
Short version is they used a TD04 from a forester, cheap cooler, ecu, injectors.
Made 145rwkw or something.

so wew are realistically talking $4-5 K ?
including tune.

yea Patchy had an adaptronic in yrears past. It had 104 rwkw. it was great at WOT...but cruising was a bitch. as well as city driving.
I'm just hesitant with the mapping of an ECU. everyone alwas goes on about max power & so on. no one ever talks about drivabilitie.

I have dríven an awesome set up once. Ampz's set up was perfect. cheap drivable, not peaky whatso ever. Consistant power delivery as well. I'm sure he was running a megasqirt piggy back.
bjones had a pretty good set up. but his is/was a different ball game. But he had so much power It scared the crap out of me.

this would have to be a work in progresss.

bit like the paint job. this latest episode has taken almost 12 months so far. But I'm almost there.

Yep, again depends on what mods you have, for example a heavy duty clutch will be needed.

Im not going to start fights by asking who tuned it, but its all in the tune. 80% of what makes an engine package enjoyable is inside the ecu. The other 20% is parts choice and setup.

A stock motor can make enough to scare the vast majority of regular people.

i used some rx7 injectors and a jaycar DFA for fuel, i know it's a piggyback but it has 128 load points so it's very tuneable. worked fine on mine which had 120rwkw on its first dyno tune and there was plenty more potential there but i left it at that. jaycar do a programmable timing unit too which has a map sensor capability for timing but i haven't got much info on that one yet, am looking into it.

gerard and boags both drove the car ask them for their impressions. it was a bit laggy but that was due to the crap old non ball bearing turbo and lack of timing control.

[Skinny Jim]

oh hang on they're qld blokes... yr sydney right?

[NitroDann]

I have bigger injectors and a dfa on a rally car of mine. The issue is not being able to control fuel for rpm vs boost.

And of course no ignition control, which isnt a huge deal on a mild n/a car.

yep the dude who did the dyno tune had the same concern. if $$ permit a mspnp would be the way to go, agreed.

[StanTheMan]

so which turbo should I bee looking at or researching ?
I want smooth & progressive delivery.....or as smooth as possible with a turbo.

is there a guide for dummies?

The only option for me would really be get little bits at a time over a period of time. Then get someone to do the plumbing when it ready to bolt on.

opinions on how well the NB8A brakes would cope with say 130-140 rwkw?
Clutch is a heavy duty exedy....one step up from standard....so perhaps that needs upgrading. Its done 100k km. My original clutch did 190k km so by the time I could potentially be ready for this, is about the time the current clutch will start feeling a little toasty.

diff & drive shafts are NB8A.

[Skinny Jim]

dann's write up is the best dummies guide i've seen so far. also have a look at the mighty car mods videos for turboing an mx5.

mcm used a td04, i reckon thats a pretty good option.

nb8a brakes will be ample, just get some decent pads.

buy a welder off ebay and tack the plumbing together yourslef, then take it to a pro to finish off or just do it yourself (after lots of practice)
