Engine what is it about the 1zzfe?

what is it about the 1zzfe?

what is it about this engine that makes it so un-moddable? u can add I/H/E but youll get extremely minimal gains... is there something about the engine? that makes it less mod-able than say, a honda b series engine or any other popular 4 cylinder.. is there something extremely obvious that im not getting?

or is it simply a lack of aftermarket support, interest and research because of low demand and low potential for profit?

As far is you not being able to get much power from minor mods like I/H/E, that's typical of all modern engines. Same goes for the engine management, there's nothing to be gained by tweaking the stock system. Engine manufacturers have pushed the limits of modern engines so far (so as to get the best performance while still keeping the government happy) that there is literally no "free power" to be gained anywhere.

That's why I only do major conversions and turbo systems and I don't play with the little stuff. The only way to get noticable power from any modern engine is with power adders (forced induction). End of story, as far as I'm concerned.

To answer your other question, yes, there is a lack of aftermarket support. The simple reason is that there is no demand. The Corolla is the best-selling car in history, Toyota acheived that not by catering to an incredibly small enthusiest group, but to the general population who, you guessed it, aren't looking to spend on money on performance parts. I mean, I developed a rear disc brake conversion for the car and sold ONE kit. ONE KIT! The other one is sitting in my shop costing me money.

You don't always need forced induction to get noticable power gains. If you know what you're doing and go all NA on a silvertop or blacktop you could have a pretty potent powerplant. I do agree with you though, forced induction is the easiest/most cost effective way to get large power gains. And yeah, not many companies make aftermarket parts for the Corolla. Its an economy sedan built for getting from A to B with enough performance at hand for the average car buyer to be satisfied, that's all. If I was an aftermarket car parts supplier, the corolla would be one of the last cars in line to stock parts for simply because of low demand, reguardless of the fact that there are forums filled with people like us begging for a bolt on turbo kit, or a rear disc conversion, or performance cams...etc...

If those people would actually buy the parts they beg for *cough*reardisc*, it might happen.

/\ that sucks

how much is for bachelor option #1?

Monkeywrenchracing - about $850 for the big bore + high comp pistons, another 750 for rods..

Edit: Plus engine management, etc..to do it properly and reliably, you'll probably end up paying about what you'd pay for a turbo.

eh I guess screw minimal mods and go straight to boost then lol I was thinking on getting exhaust, intake (which I already did lol) and a better grounding kit for a small kick in power cause my car is SLOW as hell!!!! but now reading this up I guess it's all about boost now for the 1zz man...

MWR is good depending on what you want to do. you can go to ARIAS Pistons, Crower and MWR for parts and you can accomidate to what you want and for compression ratio and for turboeing, supercharging and NOS wet for dry. ARIAS is very expensive but well worth it.

and what kind of gains are we talkin about with option 1

I'm guestimating you'll end up with ~140whp..but I really have no idea.

i spent 3K+ to fix mine and the WHP was rated at 210. what i did was take the specs off MWR and modified them to accomidate my engine. ARIAS charged me 950 for the pistons and Crower made the connecting rods and cams that was 800 total. a local Performance shop charged 300 for the block and crank mods. everything else was in parts. i paid an additonal 600 for the labor for the mechanic who did the work.

/\ this was NA horsepower?

i can no longer sell anything off my engine since when it blew it broke everything.

Have a dyno slip? I highly doubt you pulled 210whp out of a n/a 1zz. Heck, the 2zz in the Lotus Elise makes 190 at the flywheel..

i don't know but i do know that i had a 125 shot of NOS setup. Slip nope i do not have one.I took it to a local performance shop and this is what it as reading. All i remember is that i just gave it gas and it pulled very hard and first gear would peel out hardcore and second chiped quite a bit but no where near as bad as first. the fourth day the damn engine blew to shreds. this was at a 30 MPH roll.I remember the engine ran a bit hotter than normal but they said it had to do with the NOS. the engine only held up three times with the nos. the third time was the charm for it to blow up.ARIAS said it would not warrant the pistons because i failed to tell them i was going to add nos to the car but yeah it was my fault because we just put it on there all of a sudden. and i told them it was only to get "slight gains" but i have to admit they held up quite well. the timing chain was the cause of everything the cams loked up atop and the crank kept going and everything gave out. the block and head even cracked. i floored the shit of out it in D drive at 30 and it held up till it maxed past 110+ mph.Now i regret it at the same time becasue i really need to get my car running.again its not excatly a 1zz (it was) or a 2zz it had very high torque and the power didn't really kick in until 5K rpm.

well... I rather get NA power than Turbo... personal taste for low end power... as I rarely pass from 15% throtle 80% of the time

125 shot!?

Are you sure there was oil in the car? If you ran out of oil, your cams & the bearings could've seized up..pistons smack valves, etc..

You're still talking about a 4cyl 1.8..not the most torquey motor on the low end.

eh the 1zz lacks of some torque

my car was subjected to some hardcore abuse it took it very well i'd say.i finished up my tires like nothing and it dran gas like a mofo. it may have gotten 35 to 41 mpg but man i drove it a lot. 22K miles in 9 months what do you think.

oh trust me there was oil there i made sure of itand the engine did not lock up the chain broke the the crank and connecing rods and everything else. like i said i maxed the engine to its limits. Now I regret doing it.

yeah it had oil but it burned up quite a bit of it when i checked it it was below the low level mark and the light went on and BAM! the engine just blew.it sounded super loud that day like if a shotgun went off. my friend and i had a ringing in our ears for days as well as the guy we were racing.

lol yea... till you pass 2000rpms or about 21mph in 1st gear you fill the pull

oh it pulled, so hard. that i to hold the steering wheel with both of my hands.

haha u show off man lol

I shall leave then..... *tear*
