Question about Twin turbo kits

SNSD YOONA

Hi all

I got the quote from local tuning shop in Melbourne Australia, approximate 12500 US dollar, this is include fitting the TT kits and tuning. They claimed that they can achieve 410 rwhp.

My question is
I. Does the figures look all right? what do you guys reckon?
II. They also recommended me to go for oil cooler, boost controller, LSD and Clutch. If im not going to get all of them, Which of them do you guys think are necessary?

The twin Turbo kits include

•Cast iron exhaust manifolds
•Turbo manifold heat shield
•Garrett's ball bearing water & oil cooled turbos GT2860
•Front mount inter cooler
•Aluminium inter cooler piping kit
•Speedpro braided oil and coolant supply and return lines
•K&N cold air intake filters
•50mm blow-off valve
•Upgrades fuel pump
•Upgraded injectors
•ECU remapping hardware




Cheers

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.

Only 410? What octane do you guys have? I get 490 on 91 octane.

- Oil cooler...MUST
- 5 or 6 puck clutch...MUST.
- Lightweight flywheel...meh. I think they help with throttle response but they add noise and it is not a good one. Up to you.
- CSC...your stock will fail it is only a matter of time.
- Boost controller...I have a 100 octane race, 91 aggressive, and 91 safe tune. Each tune has a boost controller setting. I don't know how anyone gets by without one. I guess if you only have one map you don't need one.
- Deal with your stock cats. If you aren't removing them just understand that you will be replacing them in a few years.

I'm with theDreamer asking about the fuel pump. Fast Intentions has proven that the stock pump cannot scale. This is an important upgrade.

Would you tell me which brand of fuel injecter and fuel pump are you using? appreciated

Another factor would be which kit are they getting you. If it's the kit I think it is I suggest doing research. There's a fellow Aussie member who is having a nightmare trying to deal with said company.

ANMVQ

The pump and injectors usually depend on the manufacture of the kit, usually Bosh EVO14's and DW fuel pump. But I will let him answer also.

kinda looks like the GTM kit. if it is then go with a different kit would be my suggestion.

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.

It's not GTM. I think their wastegates are on top. I also think they use actual connectors and not silicone things for joints.

the BOVs were up top on the charge pipes.

the wastegates were all internal except the tuner kits had external dumps.

The intercooler doesn't look like its from a GTM kit either. I've torn the front end of a GTM TT kit apart to replace a leaking radiator before so I'm pretty familiar with it.
