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.

Keep forgetting that not everyone has a LSD.

And I still want to know why only 410hp... A Nismo with bolt-ons will give you 310-320. I'm not sure I would pay over $10,000 for another 100hp. I have to be missing something.

maybe it's in metric hp numbers? like all the euro guys post PS and KPW or whatever numbers?

just a thought because i agree with you. pretty mcuh any tt kit bumps most guys close to 500whp or tuned down for power wants or restrictions etc...

On their website they are using a Dynapack dyno. Hey dyno guys does that matter? I'll keep looking at their site.

Revzone

...seem to be AVO fans for injectors and pumps.

*Edit: Can't find any info on this kit on their site. OP, ask them what fuel they used for 410, what dyno, and if they have any dynos. I'm really curious now.

IIRC i think dynapack was the highest numbers? or the lowesT? idk it was one of the two lol

Arrvaxx · 08-20-2014, 02:32 PM

Wow. They work on a lot of cool stuff based on facebook.

Rid3_FaM0uS · 08-20-2014, 02:35 PM

ill leave this here for you guys to decide if that's the "GTM" kit or not. now one thing I will point out is that HKS made a kit for the HR 350 EXACTLY like the kit GTM produces(ed)[lol] same cast manifolds and all that good stuff so they could also be sourcing manifolds that route as well.

Arrvaxx · 08-20-2014, 02:36 PM

Huh..according to this the Dynapack has the highest numbers... -.- I'm getting more and more curious with everything I look into.

Differences between dyno #'s: Dynojet, Dynapack, Mustang.

410 might just be the base tune they supply with the kit so the shop might be saying it will be "tuned" but just using the canned one which is probably 400-420HP.

in australia the water in the toliet goes the other direction right? maybe the dynos do too? lol

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.

Ok that might make sense. My baseline was 395 on stock fuel system and 495 after tune and new fuel system.

But since he is getting a tune...the final expectation is really important. It affects his decisions. There is a big difference between 400 and 500hp.

To phunk's point...after 450hp you need a better fuel system and LSD becomes much more important...you also need better than OEM tires! At 495 I can spin mine in first and second without effort and chirp them like crazy in third.

But getting a tune and getting a dyno tune are 2 different things.
They be getting him a tune but it is just generic, and for an extra fee you get a dyno tune (those add on costs).

Really good point. I am Mr. ASSume guy today. I assumed that if I was spending $12,000 on turbos I would get a tune. Without it I am spending all that money for just 400hp.

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.

phunk · 08-20-2014, 02:53 PM

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.
