rods and pistons available

[battleversiontc]

crower rods available for the 1nzfe motor retailing around 750 bux
cp pistons available in two sizes std(75mm) or +0.5mm (75.5mm) comes only in 9.0:1 compression 600bux
if you need info on where to get em let me know
figured i let everybody know since i already have mine

[cali yaris]

Pauter rods are just as good and less expensive. CP pistons can be ordered any compression you want. I got 9.5:1

Nice to see more choices available for us now!

[battleversiontc]

you know of any crank options out there

[Tamago]

so for 1400 dollars you can buy just two parts necessary to build an engine that won't make as much power as a 4EFTE with 300 in mods... hmmm

swap=better bang for buck

[cali yaris]

^ I see taking a break didn't diminish your sarcasm.

battle, what specs would you like to see in a new crank?

[battleversiontc]

well maybe just a little more beefy to handle higher boost or maybe a stroker kit

[jkuchta]

I'd be willing to bet the crank can handle whatever the top end and the stroke can produce.

[cali yaris]

+1.

I'll be hunting for over 300 whp on the stock crank.

[battleversiontc]

lets us know how that turns out

[xbalance]

how high the compression rate 1nz-fe engine can take?

[jouna]

well if it can handle prius pistons 13:1 i rest my case

[taKuto]

do you have more info on the prius piston setup jouna? We'd like to all hear more about it. The power it puts out, octane fuel, long-term reliability etc.

[cali yaris]

I haven't heard anyone (at least on here) who has actually done that yet. So Jouna's data may be the first we see on this.

[at3GG]

What needs to be done to the pistons fro ma Prius to make them work with our motor? Anything? I really know nothing about internals....I know higher compression=more power with NA applications but thats the extent of my knowledge. I assume it wouldnt be a straight up swap ie: 1. pull out 1nz piston 2. "drop in" Prius piston 3. Drive away happy. Is this anywhere near a reasonable goal for a budget minded modder?

[Tamago]

well if it can handle prius pistons 13:1 i rest my case

prius is an atkinson-cycle engine lol. operates completely differently than an otto-cycle.

The Pauter Rods are much better than Crower Rods and more expensive I have paid $859 for Pauter Rods :smile:

i knew that was coming......

[jouna]

bitchin rods....and yes. prius pistons... open engine take out factory pistons and put in the prius pistons with prius bearings and its done over here they sell by 85 a piston and the bearings 125 the set.
tamago
in the prius engine the thing that gives the compression is the pistons not the cycle. the cycle is for energy efficiency only but the engine is the same so pistons will fit that easy with prius pistons installed you'll have a 10 to 15 bhp gain. not so much? well you add that with proper tuning, headers, pulleys all the goodies and you got yourself a pocket rocket. when we put pistons like this we use premium gasoline 92 octane and with tuning it's all good no back fires

[taKuto]

since you mention tuning, you'd need a piggyback to run those pistons or can you get away with the stock ecu ?

[at3GG]

Seriously? I guess I'm sorry for asking a question. This is a discussion forum...you apparently know the answer so why would i google it? Kind of takes away from the whole forum idea doesn't it. Dont really care to know the answer anymore, good luck to whoever tries any of this out.

[cali yaris]

I have paid $859 for Pauter Rods

I didn't. :smile:

at3GG, I don't know the difference either.

[at3GG]

oh well, at lest im not alone lol so what gains could be reasonably expected from higher comp pistons?

[BLAZINBLUEVITZ]

at3GG, I don't know the difference either.

coming from a prius owner thats a shame.....

[Giupo]

I didn't. :smile:

You are Fortunate :thumbsup:

guess how i learned about atkinson cycle engines... ;) think it was on a forum?



The 1NZ-FXE is the earliest 1.5 L (1496 cm³) version built in Japan. Bore is 75 mm and stroke is 84.7 mm. It features forged steel connecting rods and an aluminum intake manifold. The engine has a high physical compression ratio of 13.0:1, but the inlet valve closing is retarded. The net result is that the engine has a greater effective expansion than compression – making it Atkinson cycle, rather than the conventional Otto cycle.

so, just because it has a physical compression ratio of 13:1 it does not mean that the pistons/rods are subjected to typical 13:1 compression forces. in fact, the prius only revs to 5000rpm, so you'd want to take into account these factors.

it's not a 'SLAP IN SOME PISTONS AND RODS FROM A PRIUS YO!' solution.

[ChinoCharles]

Dude, I think my VTEC just kicked in.

How much are Pauter rods? Don't give me that can't tell you crap either. :laugh: Non-vendor pricing of course, Garm.

you're a dick, all you had to say was it didn't work. we don't need proof we just need someone with lots of posts to say it's a bad idea. why would we want to go to multiple reputable sources on the internet when we have a forum full of people who know everything?

you keep getting banned b/c you've never offered up any real helpful info and you don't even own a Yaris.

the xA engine bay <> the Yaris engine bay, who cares if you've proven that a well thought out turbo can fit in both with minor modifications.

before you start bad mouthing people you should really do some research, the toyota rods aren't terrible, not like you've ever broken one....

yes yes you do.

that and Rods/pistons. :D

you ever find out cost of parts to build the 1nz?

it's pretty stupid expensive for what you get out of it. :(

[ChinoCharles]

Well, it is and it isn't. I figure if you put the cost of the car back in you could have a 10 second Yaris. $25,000 for a 10 second car isn't bad.

You really have to love the thing to go that far with it though. I honestly just love the little Yaris. I know there are better cars, but I don't want 'em! -folds arms-

[Russelt3hPirate]

not my point.

and a 10 second yaris would be really boring to drive, plus i highly doubt you could make it reliable or repeatable 10 second yaris for $25k ON TOP of the car price.

point was it's really expensive to build a yaris motor and there is no proof out there that they'll be reliable when built or will make significantly more power.

it would suck to drop that $$ into a yaris and not getting any return but an unreliable motor :(

[justjesus]

...

That is great! I hear you on the love, man. Though right now, I'm more in love with my CRX. :iono:

[Russelt3hPirate]

That is great! I hear you on the love, man. Though right now, I'm more in love with my CRX. :iono:

I love the yaris too, I think we all do.

with some light wheels, suspension, racing buckets, and a low boosting turbo (and supporting mods) i think you could have a mildly reliable kick ass little toy.

[fuji]

Getting back on subject - back to takuto's post - you just have to add the pistons with new bearings? WIll the stock ECU handle this???

Anyone have an idea how much it would cost for a mechanic to open up the engine and install the prius pistons/bearings????

This holds the potential to be a very effective an hoprefully not too difficult mod. Sombine this with a few othe smart mods and our engins could make quite a bit more power!

they'd have to remove the entire engine to do this.

and if you want any form of reliability you'd want the block to get honed and potentially bored out slightly to clean up the cylinder walls.

no point in spending $1.5k in parts to not have them work correctly after installed.

you don't gain any power from putting in new internals, you gain the potential for more power. You also gain the potential to break alot of stuff.

if you're on a light budget it's smart to leave the motor alone.

[battleversiontc]

all i know if it took 25k to dump into the yaris to make it go 10's id do it just because i know my smaller displacement motor will be beating up alot of the bigger displacement motors cause its all about the power to weight ratio. and to add you can still have a reliable yet highly modified motor all it comes down to is building it correctly tuning it correctly. theres alot of highly modified cars out there that are dd and still reliable.

[at3GG]

1. 10 sec yaris= boring?? WTF!?
2. What was this thread about?

[Russelt3hPirate]

there are exponentially more poorly modified cars built by people who "think" they did it right. :bellyroll:

any of those Yaris's or 1nzfe's? haha

[battleversiontc]

rods and pistons

[Russelt3hPirate]

1. 10 sec yaris= boring?? WTF!?
2. What was this thread about?

to get a yaris in the 10's you'd need to have huge drag slicks, and a motor that didn't make any power below 6k rpm.

it takes alot of home cooked quality engineering to build a 10 second car for sub $12k btw, then again since we're bench racing we might as well say we can do a 8 second yaris for another $3k. :bellyroll:

a fully caged, stiff ass suspension, properly sized wheels/tires, and mild turbo kit Yaris would be a hell of alot more fun (and cheaper) then a 10 second yars.

30 minute lapping session > 4 10 second pulls :thumbup:

[battleversiontc]

i actually know alot of 1nzfes that are pretty beefied up and they drive it daily and beat on it like every weeked yet still drive home and the next day and so on its called the xb

I'd love to see them.

and if this has been done why hasn't it transferred to the yaris?

you'd think with all the "beefed" up xB's running around you'd see some of it transfer over.

i'm going to do the .20 prius pistons and forged rods with all the goodies ''e manage ultimate 1zz throttel tc injectors ect. and lets see what's going to happen

Maybe 10 seconds is pushing it, but 10 bucks says Garm puts an 11 second road course monster Yaris on the ground by the end of next summer.

[Malaya1221]

leslie armendariz's xb ran 12.97 at 18 psi on slicks, tube chassis(1750 lbs car) and a buillt motor...garm needs more work to hit the 13, 12, 11 second mark...hope he does...

phew some elaboration was all i was looking for haha ....to simply say a 10sec yaris would be boring...with no reference to what it would boring compared to...ex:road course time vs drag strip time...struck me as odd. Point taken now though. :thumbup:

keep us updated, definitely would like to see how things work out for you. Make your own thread once you've got some progress, this thread is pretty much going nowhere.

[ChinoCharles]

I like alfalfa sprouts.

Rods? Pistons?

[Russelt3hPirate]

ok.. so high compression pistons from a prius will not work..

you have enough posts for me to believe you.

I guess since this isn't in the FI Forum we can't talk about low compression pistons?

[ChinoCharles]

Chino have you found out pricing for Pistons/Rods/Bearings?

Sorry, totally forgot! I know there is a site out there that sells a rebuild kit for the 1NZ, and I want to say it was around 5 grand. 500 points to the first to find the link.

$5g's wtf.

you can rebuild a subaru motor for more than 1/2 that. wtf.

screw that, I think I'd rather blow up stock 1nz's and buy new ones everytime :bellyroll:

Well, that was for a setup that you could throw 25 psi at. THERE is your 10 second Yaris.

or build a big port 7 rib 4AGE for $3000 and run 30psi and make 450whp..

[eTiMaGo]

can we at least try to keep this thread on topic of engine rods and not who is the biggest nimrod? thanks.

[scape]

running 13:1 from 10:1, constantly, is quite a leap. I would think a lot would have to go into this, or else they'd ship the yaris at this level anyways-- no?
a kit like this would need prius grade rod, crank, piston, and head; at the least...anyone see any totalled prius's lately? ;D

[scape]

not to mention the atkinson cycle engine tops out earlier, at a lower total rpm; running this setup in an otto cycle up to 6k rpms would probably push the mechanical limit of these materials

Post #20 seems to indicate that Prius pistons have been successfully swapped in and made a bit more power, but I can't tell for sure. Clarification from jouna on this point would be helpful.
