I noticed that none of the parts availible on there for the 1NZ-FE will give a single bit of HP for an N/A motor..

We need cams, we need high-comp pistons, we need good fuel management....

 

It's prepping it for boost...

 

we need, we need we need..

dude.. a 1nzfe costs 150.. thats less than you spent on that fancy cold air intake you got, or the factory "interior lighting package"...

you see my point? you can buy a longblock 1nzfe for under 300 shipped.. custom high comp pistons and rods, $800, cams $400, head work, $500, valves/springs $400.. under 3000 dollars for a reliable, well built motor. and that's before the 100shot of nitrous you'd be able to run (if the ricer is strong in you) ...

try doing THAT with turbo.. ain't gonna happen.. $/hp, i guarantee NA will make you happier than turbo, mostly because it'll be "sleeper" (yes, i am a ricer).. if you autoX, you'll appreciate a NA build, as you do not get thrown in with the big dogs as long as you do just a displacement increase, valves, and agressive cams.. turbo your egg or box, and you're running against STREET MOD.. UNLIMITED MODS.. 500WHP AWD S4's turbo vipers, sick as hell Evos, STi's etc..

i will be building a 1nzfe before all is said and done. and i'll put those puny turbo/sc kits to shame.

cliffnotes: quit _____ing, go talk to real companies like ARP, Crane, MonkeyWrenchRacing, and see what they'll build.

 

^^ I want to go the NA route too...any info to get started would be much appreciated!

 

too bad a built na motor probably wont pass smog yet if you had to smog unlike f/i you cant just unbolt the pieces...

 

you just have to tune the mixtures right is all and mostly keep a cat on it.

 

you don't know cali smog.

 

I'm totaly into N/A buildup. The problem with that is, I'm not going to bankroll prototype parts... Simple as that. I'm a college student, they should have some of this stuff availible already, considering the amount of stuff done to 1NZ-FE's overseas. C-one makes parts for our engines, at least an ECU. If that thing has OBDII compatibility, I would be all over it. Cams seem simple enough, silly that someone hasn't ground some custom ones really. I would imagine with a P&P, cams, high-comp pistons, valve spring/retainers, and fuel management, you could make the engine a real screamer. Considering how much better the INZ-FE is than alot of 4-cyl motors on the market, and it gets almost 0 real parts support, thats pretty sad.

 

like i said before...if only i had the money to ship my monster of an engine to Japan! oh the wonders they could do....does anybody know BTW how much hp the cars that race in the Vitz Cup are putting out? NA or Turbo?

 

I think you would be alright Darren, especially if you let your ECU learn everything and try to compensate for it...If they are only doing a sniffer test then you should be alright. When your fuel trims get maxed out, dont pull the fuses, and let them test it then. You will have a richer than normal A/F ratio I would say but it should still pass the test.

 

unfortunately they do a dyno test not just sniff sniff.

 

Dam man...that sux a lot. I really hope that NY doesnt resort to doing stuff like that but the way everything is going, I wouldnt be surprised if it happens within the next couple of years

 

Depending on the class of the race, most put out between 170-190whp.

As for cams not being a challenge. Being we have VVT-I, its a huge challenge to just swap cams.

Darren, quit your complaining and just go for it. lol

NC has an emissions test, its new. I had to do it last year. (first year they've done it) I believe its just a sniff sniff test, infact, i know it is. I haven't seen any emissions spot with a dyno or high-tech equpitment to use for emissions. *Whew*

Anyway, shipping our motors to japan would be nice. I'd do it if it weren't for the ship there, ship back expense. Not to mention, the cost of all the parts and labor for them to do it. Way too much of a hassle, if i could get the parts over here than thats one thing. However, i haven't found a website with parts i want over in japan. I wish the TRD turbocharger would fit on the USDM 1nz. Its a shame. I saw a bB video of a guy who had a modified TRD turbocharger pushing i believe it was 185whp (in that area) out of the 1.3l. That thing was nice. To my surprise, you could only hear inside the car motor and exhaust until he let off the gas for the nice BOV sound. Love the sound, but i'd love to meet him and find out how they manage to sqeeze so much whp out of a little motor, and still keeping it safe.

I'm used to dealing with 1.8s, 2.0s, 2.2s, 2.4s so on. But 1.5L is a different story. You can consider it a very small regular motor, or a very large mini-motor. I like to think of it as a mini-motor. Just me though.

Well i forgot why i even posted. So i guess i said everything...

Killerxromances sorry I didnt get back to you the other day, I forgot to sign off on AIM and I came back to the computer with like 10 messages from different people that day hahaha. If you have any questions shoot me a PM and I will try to help out as best as I can.

 

haha, its cool man. I didn't have any questions really, just wanted to see what was up. But thanks man, i'll definitely keep you in mind. You've definitely been help to me already, if i can pay back the favor, hit me up and i can answer any questions you might have about something.

Take care,
Cya

 

if i may ask if you looked at the parts area on the website there where 2 S/C and 1 turbo
that reasonaly priced. wouldn't those get you the hp you are looking for?

 

If he still wants 200hp to the crank, that would be a 90hp gain off just a sc or a turbo. No company right now has a f/i set up running that much PSI. Definitely not safely.

120whp-130whp is what you will see just adding a s/c or t/c on the 1nz. Doesn't sound like a lot, but trust me, power to weight, gearing, it is. As for the goal of 150whp+. Daily driver? He/she/they/whoever will need to spend an additional $5,000+ on custom parts to keep it reliable. So to answer your question, no.

Did anyone see that post by ZPI about their crank pulley? It mentions that they will soon have rods and pistons for the 1NZ!!

Yep!

ZPI has been working on their xb now for a while, they will be coming out with a lot of stuff after the 1st of the year.

just read that nice.

how much do pistons make a difference anyway? bleh i am gonna go do some searching lol
