Jason,

Yes I am considering the Zage turbo kit like you received and then have a shop perform the tune for me. Not sure if I am inclined to do any ecu tuning myself even with that thread you shared. Is there any differences from the Zage kit to a standard eBay kit? I don't know much on boost and turbo quality as my only previous turbo'd vehicle was a diesel truck.

Your thread on the stock engine can take is what I read and figured I would try to have my tune stay around 7psi. Decent power gain and yet a little lower than what the stock internals should be able to take. If it blows, then I guess I will be rebuilding a new block with forged internals and pumping those numbers up!

 

Also, what injectors did you end up running on your Fit if you can recall?

 

im running rebuilt 550cc from eBay. Make sure they’re refurbished in the states and not overseas.

the turbo kit from Zage fits like a dream. There’s a pipe that goes between the ac compressor and the subframe that’s would be darn near impossible to fabricate without a ton of work.
Also the turbo inlet pipe from zage squeezes between the shifter cables. A perfect fit.

it’s worth the extra money. Downside is they use a proprietary four bolt exhaust flange on the hot side of the turbo so you’re stuck with the stock turbo or you’re going to have to fabricate your own down pipe. But their downpipe is amazingly good.

if you build the engine be prepared to spend a lot for not much gain. Running 10 psi on an electronic boost controller, 6 puck clutch, lsd conversion, forged pistons, forged rods, and the normal goodies I have probably $4000 into the engine and setup for around 170 wtq. More once I get the piggyback ecu controller fully tuned.

granted the car weighs 2300 pounds.... well 2500 pounds with my fat butt in it. But you’re hunting double digit power number increases per $1000 dollars

i wanted something different. Everyone has an RSX, SI, or swapped hatch. No one at the 1/8th mile strip brings a boosted fit complete with power steering and air conditioning.

 

Jason, you're a wealth of knowledge for me. Making this easier for me to understand everything.

When you tuned your car, did you do that right away before driving? I am wanting to order and install, but do not have a local tuner lined up and not sure I can do it either. I am wondering if I should wait to install until I get a tune scheduled, or if it would work for the time being without an ECU adjustment.

I contacted zage, and they did not believe that an injector upgrade would be necessary if I was only planning on running 7psi of boost. What is your outlook on that? If I can add about 30 WHP/WTQ on stock everything, then I would be more than OK with only adding the turbo and tune. I want this to be my daily still, so I assume that would be the best route to pursue?

Maybe I can also use this as a learning experience on boost as well and can add the twin turbo kit from OVTune to my 2017 Tacoma down the road!

Thank you!

 

you can still daily the turbo car as long as you get a clutch that’s stage 3 or less. The hardest part of mine is the clutch. That 6-puck unsprung clutch is a bear to get used too.

on a side note, I’m putting in a bigger turbo this weekend. It’s a GT28/T4 hybrid with a 70mm compressor. About 25% bigger on the cold side but the same size on the hot side. Also re-Wired the piggyback so “technically” the turbo and ecu will take 25 psi but I don’t think I’ll try that haha. But I will tune for 18 psi or so.
