View Full Version : Engine Blown...

Boosting between 8-9psi, high RPM, ignition timing was off. :( Guess when they say it's difficult to hear pinging after 4000rpm they aren't kidding.
I shouldn't have been as hard on it as I was when I knew it wasn't ready. It was a mistake, and an expensive mistake at that, good thing I can afford it. Lesson learned. Note to all you guys messing with your car, be sure you are finacially capable of fixing your vehicle if something goes wrong. Adding the boost controller, FMICs, etc etc is the easy part.
The only good thing about the ordeal is now I'm going forward with a bottom end rebuild. New motor, forged intenals, port and polished head, disco potato, custom 3" downpipe, possible new clutch and my new GB motor mounts were already on their way, and a few extras, are being added to whats already done to the car.
I've proved it was an unreliable 240whp, when I get the car back it will be a reliable 350whp if not more. I was always planning on doing a motor rebuild myself one day, when I could do it in a garage of my own down the road, but I don't enjoy paying x amount a month for a car thats sits static.
Good Luck!

Ouch thats an expensive little hole you got there. Good thing you already had big plans for the car and the money to do it. Good luck!

240whp on stock internals & no race gas...even with tuning, wtf were you thinking? (screwy)

I wanna know what mods. 8-9 psi on stock turbo? Why was your timing off?

He was running 9psi on my stock boost maps. The maps were modified, but from what I was told, the spark was not delayed enough for 9-10psi and there might not have been enough fuel added. His mods are very similar to my current setup.

08-20-2004, 03:57 AM
how much different were the maps compared to the stock ones? Ive been pushing 8-9 and just curious if my engine will go. Does each MSP have different maps to a certain degree?

also are you having to pull alot of timing with the mpi to run 16psi? thats what your at now righ?

Sorry to hear about that, good to hear that it hasnt bumed you out to much though. By the end of all this you should own half of kinetic. Good luck.

My engine went last weekend; a rod right through the bottom. Does anybody know where I can purchase a new fully built block with good internals?

Yea what else exactly did he have in his car? No way it just blew running 8-9 psi with nothing else. Were you racing? Gunning it up a hill?

Here are 505zoom's relevant mods. Are these what you have done to your car?
Manual boost controller
Modern Performance piggyback fuel & timing controller
Modern Performance dual 45lb secondary fuel injector setup
iON Performance front mount intercooler
Custom blow off valve system w/ HKS SSQV
3" turbo-back exhaust w/ Saber muffler and single hi-flow cat
Customized Injen intake w/ A'PEXi filter

What was the wideband saying?
In any case... it'll only get better from here.
BTW...I think you win the SMALLEST HOLE MADE in a BLOWN ENGINE award! The whole is so "cute".

Ha! I thought the same thing. That is the cleanest blown engine I have ever seen. The rod punched a perfect hole.

Always sucks to blow the motor.... at least you have strength and good tuning to look forward to in the future. :)

Wow... why can't our engine be stronger!?!?!

If our engines blow at 8-9 psi than I'm afraid that ALL msp engines will eventually blow! Even stock ones! There must be somethin' missin' here, at least I hope...

He had a setup similiar to 505's so it was modded quite a bit.

his car wasnt just 9psi with some bolt-on's. he has mpi,fmic,full 3'' exhst ect.....he was making 240whp @ 9psi, thats pushing the limits of the rods on the fsde. most people will be able to run 9 psi for a long time simply because they wont be pushing that much hp at that psi level.
thunder
08-20-2004, 02:01 PM
Pfew! Then it must have been somethin' to do with the tuning itself (a/f, spark etc.) A rod won't easily snap if there isn't detonation, usually.

08-20-2004, 02:06 PM
also are you having to pull alot of timing with the mpi to run 16psi? thats what your at now righ?
Yes, I ended up taking out a total of 17 degrees to run 16psi with torco in the tank. This is in addition to using 60's for my injection map and 30's in the analog map. Phrisco was running almost the same hardware/mechanical setup as I am, but his mapping was not set for 9-10psi. He had probably between 10-20 in his injection map, and probably less than 10 in his analog. Ignition was only delayed about 10 degrees. I feel partly responsible for this, I told him to take it easy at stock boost until he was sure that it was not detonating, but I think I failed to relay how much fuel to add and how much timing to take out when he was ready to crank it up.
Sorry man, I hope it gets up and running again for you soon.
dude, sorry to hear your engine is "un-naturally ventilated". :( Looking forward to seeing that thing rebuilt. what are you gonna be riding in the mean time?

Ok jeez relax here's my mods.

GReddy Turbo Timer
Some people have good results with the piggyback, others dont. Even with all my maps at 0 I was still pinging, something was wrong. I thank Rich and Nick for their support thoughout the ordeal.
Yeah I should've taken more timing out and added more fuel before I opened it up, my mistake. That's really all I have to say about it.

sucks, but atleast you can afford a very nice rebuild setup :)

So just to make sure he was at nine psi and he blew mostly b/c of his tuner right?
Im scared that I might blow my motor if I don't have fuel management and he does!!!
NeverSober
08-20-2004, 03:35 PM
Just because he had fuel managment doesn't mean it's safe to run higher psi. He blew his motor because of the tuning. You'll be fine at 9 psi, I am running 13 now with no FM. Yashooa has been running 12 psi with no FM for over 20k miles. Im at 20k now and have been running higher boost since like 6k miles.

what are your mods never sober? MIne are intake, fmic, hardpipes, colder plugs, and soon to be custom exhaust. I plan to run 10 psi hopefully that's safe, if it isn't then I will kill myself, cuz i don't have extra thousands of dollars to buy a new engine. I've taken more than enough precautions on the car.

Wow..how the hell...
I am not even sure what to tell you...on 9psi..That's scarry..you must have been runnin lean...next time make sure..you take all precautions before just punching it.
Good luck on the rebuild!

If the timing was too advanced or the A/F was too lean, it wouldn't take long to snap something at that power. Everyone has to remember that just because he has engine management doesn't mean he was better off. He could have had it tuned worse than stock. A lot of people lean out the A/F to extract more power, but our cars have a higher, less boost-friendly compression ratio than other turbo cars. He has extra injectors, too. One or both of those could have failed at a high rpm and caused it to lean out.
The safest way to get power out if these cars has been shown to be stonger, lower compression pistons and rods, engine management, and supporting mods (intercooler, etc.), along with conservative tuning. Don't run 12.5 A/F just because it gives you the most power. Not saying anything against you, PHRiSCo, you've learned the hard way. This is more for all the people that read this and think they'll blow their engine at 9 psi.
Good luck with the new engine! I can't wait to see how everything turns out with the beefier bottom end some more extensive tuning.
