200 NA horses?

[Black_griffin6]

Wow, I got a big response from this, thanks everyone.

To answer a few of your questions, yes it would be expensive, but then again I see people dumping 10k or more into 15 year old Honda Civic's.
Why 200 HP? Well I think with 200 HP and with the weight of the Yaris it would give me a good power-to-weight ratio that I could take on the track, yet it wouldn't be total overkill, I mean don't get me wrong...if I end up with more then 200 after i'm done i'd be happy with it, but 200 is my goal.

I thought about going the 2zz route but I thought it would be too complicated, since I might have to cut the frame and modify the structure of the car to accommodate a different engine and transmission. I'm also worried about how much more weight the 2ZZ with a 6 speed would add to the Yaris.
I mean quite frankly...I would love a 2zz in my Yaris, and if that's the easier option I might end up going with that because i'd love to have a yaris with a 2zz.


I like engines with a long power curve that rev high, like the RX8 and AP1 S2k, and I wondered if I could do the same to my engine without making it completely unreliable. Bear in mind, this is all just a thought i'm pondering what might be the best route for something like this.


I have thought about a supercharged build, but then I wonder what kind of supercharger to go for.
Thanks for all your insight guys, I really appreciate it.

Or curving upwards with a properly sized centrifugal supercharger

We've answered the question "can it be done?" with yes -- but it's not easy, and might not be reliable. Now let's try a new angle.

Your project, as described, would cost far more IMO. Let's start with "what is the most you can spend on this?" -- and go from there. That would result in real life guidance for you.

I totally agree and would like to add as another part what is the timeline because that can affect pricing/budget. Do you plan on a local builder or if a remote one then freight comes into play as well.

No real set timeline for this, it's just an idea for now.
It might end up being too pricey and complicated for it's own good.
Since it's just an idea I don't really know what the budget would be, it would be something I would have to save up for in the future (not the near future mind you).

I'm not an expert at tuning and modding cars so I don't know what it would cost to have it done, if it's around 10 grand as Garm said, then it's probably not worth it to me.
If I became a millionaire suddenly hell yeah i'd do it.
But if i'm going to put 10 grand into my engine and gearbox I think I would get far more out of a 2ZZ.

Really the whole idea behind this thread was just to see if it was a practical idea to get that kind of NA power out of the 1NZ, but I might be biting off more then I can chew with it.

How about a centrifugal supercharger build?

Ok, I for one misread your post then, I thought it was an actual project you wanted to plan for, not a "practical theory" discussion. My apologies.

I said more than that, actually. And, in my opinion, a swap is just as costly unless you have a shop and are doing the work yourself.

How about a new thread?

if anyone has one of the old issues of siphon(i think that's what it was called) laying around, they had a feature on a vitz transformed in japan by g-force. it was NA, but i can't recall the hp numbers...it may have been 200+?

wish i didn't toss all of them!

Thats cool I love seeing our little yarii getting mag coverage. There is an old issue of Turbo Mag with a blue LB sporting the blitz kit like when it first came out.
