you are all

You seen the latest Best Motoring Video - American Touge 2????

The Greddy turbo tuned with e Manage was able to run 3 runs in the dessert

Hey I think the 8 is good to run under 20 degree air temp.... since I did not have heat problem at all yesterday

Well, to cut to the chase and save everyone's time and angst, here's the takeaway on t/c in Australia -- see taka, I can stay on topic

First, Mazda has built at least three prototypes. At this stage there is no intention to go further with this, but if you want to speak to someone with pretty good knowledge about this kit, call Jon Waterhouse at Reliance in Canberra.

You could also speak to Joe Signorelli at Rotor Master, as his first RX-8 upgrade back in '04 was based on a t/c. He's since rejected that (might be worthwhile asking him why ) but I am sure he'll still build you one if that's your single-minded desire

Or you can buy a GReddy kit and fit it yourself -- there's probably people around who can do the tuning for you but in any case there's lots of stuff on the GReddy elsewhere in this forum.

Finally, we all know -- and I'm sure you do too -- that Ciao started building his "kit" because he didn't like the GReddy, which another member at the time acquired for him (he's probably still got it if you want a cheapie ). So, given your personal preference, you should avoid wasting time here, and sign up with Ciao and satisfy your need.

I understand another rotor workshop in Brisbane has also done some t/c work but can't recall who -- maybe another member can help.

And that's about the sum of it.

As to "conspiracy" -- sorry, that's but also fairly obvious slight against all the moderators of this forum, so take care

takahashi

Ciao did not like the GReddy kit because it is a small turbo and will never get the power he wants.

I don't think I need that much power - seeing what the car can do with a small turbo.

This is my way of tuning.

Looking at wat the US is doing with Gready. I will tune it with other management system

All exciting - and a lot of $$$$$$$$$$$$ involve

Revolver

So Taka are you seriously considering going down the FI route?

What have you got in mind?

takahashi

What I have in mind???

In that sequence before the tubro

AP caliper
P Mu brakes and rotors
New wheels 8.5" and new slicks (*I am trying Yoko this time)
Larger radiator
Some fake front bumper to increase air flow (very rice I know). I am looking at the FEED one.
FEED intake (sealed in OEM box) - since I am planning this for future FI.... :p
FEED extractor. Keep the Cat until it melts - Re place/upgrade if necessary.
Retune the car with Microtech or Motec.

By that time I will want better suspension.... I will need a Tein Super Racing or something like the Quantum spec.

Wait someone in US bust their engine with GReddy (does not look like so)
Put GReddy in with only low boost. I am looking at only 6psi with usable high rpm boost and only aiming at a useful 170kW at the wheel. Reliable power
Also by that time it would have done 50-60K km (and about 5-6 year old)... so it is time to crack the engine open and repolish it. Hopefully stronger seal will be made for FI and development are clearer....

Then I am good for a real track car.

Hopefully by that time I am earning enough money to drive a Porsche to work

Dan 8

Wow!
Didnt realise that this simple question of mine would start a war

With the reading that ive done and the research i have made , I am currently leaning towards the Turbo charge route .I have seen all the FI ,including Ciaos videos and I am very impressed.

The best part about Ciaos it is the fact that all is hidden from view and the system is reversable .The two stage power setting is also a great idea if i want my son to drive at some stage

All sounds very interesting.

Have you decided what kind of 8.5 rims you're going to get?

What does the FEED front air dam look like? Any piccies?

Have you checked out this MazFix (do I have that right?) turbo car? Might be another option instead of theGReddy kit.

You mention waiting for a US car to blow it's engine. Is that because you want to see how reliable it is long term or it's a way of getting the kit cheaper?

I agree with your thoughts re: lesser, reliable power. The drivetrain and chassis was obviously only engineered to accept so much power and torque. Makes sense that if you try to get too much out of it you're going to have things breaking on you.

I think the aftermarket industry will have you stuffed and mounted (or clone you). j/k

Revolver

More an old skirmish revisited Dan. Let's hope it doesn't return again.

Let us know what you end up getting and what you think of it. Some dyno figures would also be good if you're prepared to share such info.

takahashi

No idea on rims - what ever is cheap and light in HK. Wedsports, Rays, Volks, G light will be my choices

FEED is just an intake - I will use my Odula RAM with it. www.fujita-eng.com

No point looking elsewhere. They are not coming to tune your car at Sandown isn't it? Pointless looking overseas. Not even Syd or Birs for that matter. Not for a foreign kit even.

US people = big on boost. I am more on the low boost. I hope they found out soon for the rotor seals replacement parts though.

No. RX8 chassis CAN TAKE a 530hp 13B-REW (JIC race car). It can take anything! It is a more advance chassis you have got under your bump than the RX-7 mate I want low boost since I don't need to overhaul it every 10000km or 10 track days

I am not as hardcore as most people in the world. I just love track business. Developing my skill on set up is still a priority

Revolver

I think we're at crossed purposes - I meant the front bumper you're considering.



Now I'm confused. Does this mean you're NOT going to go FI because there's no local (i.e. Melbourne) option? Or do you want to source a GReddy kit later and tune it for lower boost?



I'm not suggesting it's not advanced or capable of development but it stands to reason that pumping out a lot more power and torque will introduce greater stresses on other parts of the car. For example, does the JIC race car run the OEM clutch, gearbox, flywheel, driveshaft and diff? Further, given the suspension and brake mods you've made and are considering, you obviously think the OEM chassis needs modding to keep up with the power and torque increase.

And we've already heard of at least one blown gearbox.

timbo

Why t/c rather than s/c, taka?
I am mindful that some quite smart people started off with the t/c but after examining the Renesis, have shifted to s/c as the FI mode of choice. I note your comments re low boost, but even so there will still be lag and heat effects with a t/c that may be minimised with a s/c

takahashi

Call me a JDM sucker...

There is a local person to tune my GReddy turbo Dave.

There are people doing Twin Screw in Japan.

As I repeatedly saying ... it does not matter t/c or s/c, as long as it is low boost, it is ok.

I don't care lag - as I drive on a 40kmh road to work (if I ever drive) and if there is no lag above 5000rpm (gasp!). It should be ok.

I just want a touch more power - not heaps of power that other smart people is aiming to achieve.

Anywhere near the stock power of 350Z is more than enough for me.

takahashi

I also stress that DO NOT think FI until you have other mods.

Thanks Dave I remember to put the flywheel and clutch in the list - EXEDY it is

takahashi

FI will certainly be the last ever mod I do... so the part coms before that will have that in mind

Gomez

A number of guys in the US have blown engines with the GReddy....search is your friend

takahashi

i should add on a well tune low boost

that is why i would overhaul the engine b4 fi...

Or do it in a just runin car and put all mod in one hit

Revolver

IC, thanks.

Revolver

Glad to see you agree with something I've said (at least partially)!

Must claim commission from EXEDY.

Revolver

OT - am I the only one who hates how the smilie list changes order all the time?

takahashi

oh yeah...

A well balanced car is way more important than a power ful one.

Revolver

Something EVERY RX8 owner would agree with.

takahashi

A well balanced RX-8 kept up with the 350Z on suspension and slicks yesterday...

This tell you set up (ie Tyre pressure and damper rate adj) is very important

rotarenvy

I have the feeling the SC preference started as people know you can't fit a large turbo in the normal location. that and possibly due to the amount of I want SC voices on this thread wanting low down torque.

as taka realises lag isn't such a big deal once your moving. people with the greddy kit state that it is trying to boost when cruising (3-4k rpm). why do you need boost below this? only drag racing will benefit and then your risking the gearbox.

SC are inefficient and heat the air. a correctly chosen turbo will be more efficient. the axialflow unit might be the solution. have you noticed hymee's comments how the SC produces boost from idle and that his expensive motec is the answer in controlling the unstable ignition at low rpm. sounds risky to me but I'm confident he has the know-how behind him to get it right.

takahashi

BIG CALL Jarl but I love your logic.

Revolver

Agreed.

I'd also suggest driver skill and experience is more important again.
