Turboed Corolla Overbuilt?

[-Shune-]

MN: ZZE122R

Engine: 1ZZ-FE

Hi,

I'm currently in the final stages of researching about boosting my car which I'm finding is incredibly expensive but oh well car people aren't sensible people. I was looking to make this car a sort of daily but take it to the track and car meets. Anyways I was just looking around at other forums and I couldn't find any that described the type of mods required for a certain power level as I don't want to spend a heap of money when I don't need to however I want to make it kinda reliable so idk. My power goals are between 275-350hp running E85, here are the engine internals I want to upgrade:

• Monkey Wrench Racing (MWR) 1ZZ-FE Engine Rebuild - Forged Rods, ARP Main and Head Studs, Ported, Upgraded valves, stock 10:1 CR
• Turbo - GTX2860R
• Fueling - MWR Injectors 630cc, AEM fuel Pump 340lph, (might do flex fuel),
• Intake - Billet Centre fed intake, Haltech DBW conversion
• Boost control - (I'm not too sure what to buy)
• Intercooler - (Anything that'll fit) 

I hope I wasn't too vague, I was asking a tuner in my area called Tunehouse (lovely people btw) and all they said was you might have to run a bit of boost so I'm not too sure how to interpret that in this context. Any advice will help, thanks.

that engine will be fine, the rods are the main thing to be concerned about. 

• The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. 
• The injectors might be on the small side, we run DW1000's.  You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head.
• You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage.
• Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum.  I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs.
• Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow.  a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator
• Don't forget about the clutch and gearbox.  These days I like the Uniclutch twinplate,  Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice.
• If you're going to give it a hard time, you'll also want an oil cooler.  I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow)
• You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point.

 

To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K
