As title says, im debating whether or not I should turbo the trix. Especially with the blowout sale from TK.

But im a bit worried of the miles i have on it. I have 112k on the odo, and I've always taken care of it (Maintence wise)since i got it at 100K.

What is there to do to make sure the engine is ready to go?

I'm a nooooobbbb at this, but seriously wanna be boosted

[snowboarder202]

compression test is a good start

[thebam]

Do u know what the numbers are for a 2zz?

[carlwithaK]

I definitely want to turbo my car, but it's running practically 180k miles and I don't want to invest so much and have the car break down.

[Whosjorgey]

^ GOOD IDEA!! ... I've spent so much on it and it may be gone soon ...with 158k on the clock, on the bright side all you scavengers might get lucky with a part out lol,

[carlwithaK]

Yea, I mean it feels like my car will last a lot longer. Not having any problems at all and I regularly maintain it, but you never know what can go down on the inside.

[Whosjorgey]

mine was perfectly fine I've done everything on time and out of the blue just blam all hell went loose, I got it at about 120ishK miles but I've maintained it In pristine condition ... you never know when something can go wrong

Not trying to p!ss on your parade, but boosting a 2ZZ motor is probably a bad idea. Many have tried and failed in glorious fashion. Getting a high compression engine with variable timing and lift to play nice with forced induction is very difficult (even for Lotus). No off-the-shelf systems here...everything is going to be a custom part and you better know a good tuner that has a dyno. Just because someone is selling a "kit" for your car doesn't mean you can just bolt it on in your driveway and live happily ever after. Even if you get it running decent, the life expectency of your motor is drastically reduced...Good luck though...if you decide to try, let us know how it turns out...

You can boost a 2zz just fine as long as you keep it reasonable.

Reasonable is < 10psi. Your compression should be at least 175psi across all 4 cylinders, but preferably more like 185+.

What's more important is that they're consistent. No more than ~10psi apart.

What are reasonable compression numbers for the 1zz? I recall reading an absolute minimum of 145psi per cylinder? Is this correct? I'm going to rent the tool and attempt to run a compression test this weekend should time and resources allow.

I have a compression tester you can use. A 1zz ideally would have 160ish across the board, but yea, 145ish as a minimum.

I appreciate the kind offer.Thanks for the clarification. If I run into any issues acquiring the rental, I will be in touch.

I drove over three years making 11psi before I ran into an issue caused by my own experiments. The 2zz loves boost, and if I got another one, which I would love to do, I would not hesitate to boost it again.
The big secret is engine management. I think good advice is to stay away from the AEM FIC. buy a hydra EMS or even apexi PFC, the other option is if you have a manual DBC you can run the spoof.

If you could further detail your experience with the AEM FIC, I'd be interested in knowing why you prefer those alternatives.

There's nothing wrong with the FIC lol.. I run it on my twincharged car as well as several other cars (not matrix's) that we built turbo kits for. If you know how to tune a car, it will work great for you.

And there's also nothing wrong with boosting a 2zz but stating X psi is a safe amount is only half the story. I would limit it by HP and not boost, you can run several different sized turbos and there will be a safe psi amount differing for each one.

I didn't mean to imply that it couldn't be done...just saying that it's a major undertaking and you're not just gonna bolt it on over the weekend and drive away happy. You better have another car to drive while you shake it out...

BTW...here's your old SC for sale:

Thanks for all the inputs!

Still debating, Ahhhh

I don't understand this from a physics point of view.

The volume of air going into the motor is X. The only way you can change X is to change the pressure at which it enters the motor. The size of the turbo itself isn't particularly relevant at this point. Your 2zz with 8psi of boost going into it is going to make Yhp. Regardless of whether that boost is coming from a GT28 or a GT40.

Is it necessary to get the Wideband 02 gauge for this setup?

Yes either one with a gauge or one like I had that was inline and read threw your computer.
