f i'm spending $12k on turbos then i would have the top level Fast Intentions kit. thats just me lol

but again i realize he's in australia so options may be limited especially with shipping costs.

well that would get you the turbo's but what about the instal, and tune, and clutch, and fuel, and gauges?

clutch? im 7AT. it'll cost me about $5k more for that :tiphat:

but i think the base price on their kit is $9k. add in some upgrades and tune it's like 12K no install i believe. just saying numbers wasnt being literal kit for kit that he has listed.

you guys are correct, dynapacks USUALLY read higher than dynojets.

based on the picture ride famous posted, looks like it actually is just a GTM kit.

The HKS manifolds that GTM copied dont have the 4 bolt flange on them... GTM added that to it for external gate option.

that's correct; regardless you and I both know it would be hard to copy a mold and "alter" it to fit a new market which you of all people should know GTM ISNT foreign to doing...

Does not seem that far off base, I would agree on the oil cooler and clutch/flywheel/csc since the transmission will be done you may as well.
Questions I would have:
-What size injectors & brand?
-What size fuel pump & brand?
-Is this a shop made kit or something by a shop in the US or Japan?

I went to the shop today, they told me that they have purchased GTM TT kits long time ago. But it does not fit properly, the reason is mainly because of Australia is right hand drive. The kit in the picture is modified base on GTM.

Bosch 650cc injectors (no idea what series they are other than *Bosch 650cc high impedance fuel injectors w/Denso plug
and play wiring adapters) and the Fast Intentions FAST-500 fuel system.

They did a whole writeup in July about their fuel system testing (happened to be tested on my car). I don't know if I should copy and paste their post...Search Fast Intentions on Facebook, read the Fast Intentions Twin Turbo thread, or just PM Tony. I'm sure he can tell you what you can get from them to drop in your setup.

Unfortunately, they normally just upgrade the fuel pump by itself.
They told me base on the kit they provided, they can make 420RWHP & 427ft-lbs for me.

If you goal is only 410rhwp, than you barely need to worry about the fuel pump. The stock fuel pump will probably make it this far, but they will probably use a Walbro 255 anyway and that is more than adequate and very inexpensive. I would only ask them so you know whats in there in-case you aim for more power in the future.

For fuel injectors, as long as you are 550cc or larger you dont need to worry about it. Only a modern 48mm body length fuel injector will even fit in there anyway, so you arent going to end up with some old crappy injectors. Again, I would only bother to ask what size they are so that you are aware what is in there if you decide to go for more power later.

The stock fuel system with just injectors and a walbro 255 is MORE than adequate for 450rwhp or below.

Oil cooler is a must. Clutch and flywheel is a must. Boost controller I would avoid, just put in the proper wastegate springs to achieve your target boost since it will be low. Add a boost controller later when you seek more power down the road. If you have a stock LSD, I wouldnt bother upgrading. If you have the open diff, then you will need the LSD.

Thx for your suggestion, it's really helpful.

yea the kit though may be pieced together since the couplers on the GTM kit had logos and the one in the pic has nothing.

Right hand drive, that is what they told me.. US brand kits can not directly bolt on :icon14:

I wish I am in US, anyway thx guys so far. I am appreciated

OK guys, I am familiar with this shop and their dyno and I can confirm that this dyno has always read LOW by comparison with others, epecially quotes from the US and even a couple of Sydney-based dyno's, which is why the OP needs to chill a little and not get too overwrought. He needs to do some more reasearch including speaking to local guys here in Melbourne with the kit ....

Revzone imported the first GTM TT kit into Oz back in 2009 (OP - check the posts by TAO on the AU Z Form - I'll PM you the details) and they had enormous trouble fitting the kit to a RHD car, so together with some more recent and well-covered GTM related issues covered in depth elsewhere on this forum, they now offer their own kit.

I know of at least 5 kits running at 420-450 rwhp on base tune, so I would strongly suggest that the OP contact some of the local owners as the dyno numbers being quoted do not replicate south of the equator .. in my experience, the numbers quoted on US dynos are rarely replicated here.

I have PM'd the OP with more information.

Great insight BGTV8.
