has anyone else had issues with a supercharged engine? my car has a little over 69,000 miles with 48,000 of those being with the supercharger on it. I haven't opened it up yet but i'm pretty sure I broke a head gasket, threw a rod, and have absolutely no compression. has anyone else had any problems and does anyone think that this could be attributed completely to the S/C?

any problems leading up to the break? or just asudden misfortune?

Hard to say, My engine was S/C'ed too. Took the S/C off about 8 months ago and blew my engine couple months back, a Thrown rod at 68,500 miles or so.. I stayed ontop of maintenance for the engine,so it still boggles my mind how it could of happened, Have been quite a few people reporting same the type of problems and they have been either S/Ced or was still S/Ced at the time of their problems.

'03 btw and 2400 bucks for a rebuilt engine.. ugh.

r all u guys running the TRD ECU? Because I'm sure Toyota knows this engine cannot handle it for long with the stock rods. But why does it warranty it if they install it. They must do something to prevent damage. anybody have the dealer install S/C and had engine blow. Did they fix it? I'm N/A, but this has always bugged me for a while.

my compadre running a s/c (installed the same day as me) blew a rod, dealer-installed btw (and Toyota employee). both of us highly modified, his an auto, mine manual. my blower's bearings gave out before the motor/head...

Yea, TRD ecu and stock setup no cai or short ram intake..

Snapped a rod here shortly after the S/C, no dealer help. So far so good on the used engine I replaced it with, but hopefully I won't have to worry about any of that much longer.

What are your current mods? Were running a A/F gauge when she let go? I have been S/C for about a year and a half with no problems. Knock on wood.

My TRD ecu went out when I installed the AEM intake so I have an aftermarket ECU and no problems yet. The car is making a funny noise like no oil but I checked the dipstick and it is fine. Next I will be checking for exhaust leak. The sound is like flubbering on slight acceleration and you can notice it when driving next to a median wall and the windows down. And I never had the supercharger installed by a dealer, that is a big no no for me.

Do you all realize that the S/C does not have to be installed by the dealer, just by a toyota certified technician in order to completely keep your warranty. Also according to a law passed by the Federal Trade Commision, called the Magnuson-Moss Warranty - Federal Trade Commission Improvement Act, there is no aftermarket part that if installed correctly on your car will completely void your warranty. It is the dealership's responsibilty to prove that the installed aftermarket part was installed incorrectly and was the direct cause of the problem with the car.

my rebuild cost me 650 for a thrown rod and bearings replaced but i was turbo'd. mileage was 64,000

I think i understand why everyone is throwing ther rods everywhere because it happened to a buddy of mine to his boosted honda. It cause his rod and main were crap stock ones. I think the only thing that you need to do to keep the car strong is replace the rod and main bearings with stronger ARP because overall I hear the rods in the 1zz are strong.

Only drivetrain mods we're the s/c, jp header and trd exhaust, i had the 60,000 service done in february and no problems since then. when i got the car home and started to look at it.. there was no coolant in the radiator and none in the oil. the only warning i had was it started knocking a few minutes before it happened. no lights came on, and the temperature gauge didn't move. no idea until i open it up i guess...

Were did the oil and coolant go? Did they just bump out or did you have it service somewhere? There was no leaking coolant or big oil slick under the car. I am super over anal with the car, I am always under the hood checking something. Good luck on get here back on the road.

there was oil, just no coolant. there were no big puddles that i saw. i was however parked in a grass parking lot at the warped tour before it happened so even it it happened there i wouldn't have seen.

Good luck getting a dealer to help you because of the Magnuson-Moss act. Ask anybody here, they got ways around that. Did anybody have the dealer instalt, then blow the engine, and the dealer replaced it?

Didn't Terrier get his engine replaced under warranty while having the S/C?

From what I got from GM Corp as long as it was installed by the dealer you are good on the warranty, otherwise you are screwed.

yeah good luck with the dealership cus they will try everything not to warranty it. if you were local i would send you to my guy who would fix it for 600 which is a great price considering anyone else your going to call will charge 2-3k. just a heads up you might want to look at a used engine cus it will be cheaper than rebuilding it.

yea i did, car had 70K(100k warranty), the problem is a toyota 1zz issue, quite a few people had the same problem and some weren't supercharged or turbo

thought i'd give you guys an update.. the engine was absolutely cooked. the first and fourth pistons were melted and rods gone. i found a engine out of a 06 corolla with 9k on ebay and got it for $1600. shipped. eleven hours later had everything stripped down, switched over and the engine back in and running like a champ. =]

You win,

Did you slap the S/C back on?
FI 1zz's seem to get thier a** kicked.

Rod comparison :

everytime i see a picture of the 1zz rods it freaks me out makes me want to drive my matrix like and old granny

now, i'm scared to drive now.....

So if the main problem is the weak, skinny rods in the 1zz engine, are there any aftermarket or stronger rods that are compatible and will work sufficiently??? And any other specific parts of the engine that might need to be upgraded, but without fully building the engine???

Yeah, makes no sense to have such a long throw and such a skinny weak rod.

Well I answered my own question by doing some research and found that MWR pretty much has all the parts ya need to upgrade. But once you upgrade the Rods you might as well upgrade the Rod Bearings, the Camshafts (which require upgraded valve springs), the Pistons (which require a Sleeve Kit, especically if you're gonna go with pistons for F/I application), and who knows what else I'm missing.........................................then for us auto guys we have to worry about all the tranny issues and those upgrades. But If I had the money to do all this, it would be pretty sweet to see how much horsepower would come out of it.

and it all comes down to, the cha ching$$$$$$.

Wow- so sad to see another S/C'd 1ZZ with a thrown rod right on schedule at 70,000 miles.
I am about 10,000 miles into my 2nd engine now, still S/C'd, and I baby the hell out of it.
Its gotta last me!
