#5199, "How many blown engines here? Statistics time!"
LAST EDITED ON 17-May-01 AT 05:54 PM (PST)
OK... this has reached a ridiculous point. People are blowing engines up left and right. My question is HOW MANY have?
It is a very sad (and quite discouraging) topic to discuss, but someone has to do it...
Oh, and the Turbo Kit doesn't matter... in case no one has figured it out yet, its out POS stock bearings, rings and pistons. I have personally seen these fail on STOCK motors... Apart from this, the crazy timing is a great factor. And also don't forget that from turbo kit to turbo kit (of the same make) not a *single* one is identically installed to the next, or *idnetically* tuned to the next, or run in *identically* the same temperatures....
BTW there IS a block design difference between years (95-96 & 97-99)..
Here's what I want to know (cut and paste and fill in):
*Car BRAND (Talon/Eclipse/Avenger)..... Eclipse *Model Year ... 95 Early Fuel System *Total Mileage at time of incident ..... 94,000 *Total Mileage Turboed ...... 3000 *PSI on Turbo ..... 10psi *Fuel System Setup ..... HRC Fuel Pressure Riser w/ Holley High Pressure Fuel Pump *Internals.... Bone stock (and as far as I know) all original. *Any timing tuning? .... No *What went wrong ..... Blown Rings - excessive blow-by, blew camshaft seals
I DO NOT want to know which turbo kit. We will only start a silly pointless little war...
Thanks, and I hope you guys help me find the problem!

Do I hear an echo in here?
>BTW there IS a block design >difference between years (95-96 & >97-99).. What would those changes be and are they significant? Obviously the measurements haven't changed neither has the cooling passages since any yr head gasket and internals will work.

>*Model Year ... 95 Early Fuel >System
>*Total Mileage at time of incident ..... Dont know used engine 109K on the car. Not really an incident it took about a month before it became undriveable
>*Total Mileage Turboed ......none. maybe a total of 40lbs of nitrous spread across a yr period.
>*PSI on Turbo .....none at the time. seldom 70 shot dry
>*Fuel System Setup ..... NOS regulator/stock
>*Internals.... Bone stock > >*Any timing tuning? .... No
>*What went wrong .....A barely noticeable tick that was diagnosed to be the early stages of a bearing gone bad. A month later the tick turned into a knock which turned into what sounded like 50 nuts and bolts were thrown into the crankcase at which point I stopped driving it.
Oh and I never mentioned it but Gtuned.com looks like its gonna be one of the best personal sites so far. Love the AFC tuning.

Thanks Always nice to hear nice comments!
As for the block changes... As far as I know, the crank bearing from a 95-96 did not fit a 98 420A motor. So I walked back into MOPAR and sure enough there were different part numbers to order! Unfortunately, size-wise I couldn't compare the bearing packages, but the 97-99 ones looked pretty much the same "design-wise". However they cost about $30 more that the 95-96 ones...
The guy working the parts at my local Chrysler confirmed that there was a design change between 95-96 & and 97-99 for the Crankshaft bearing only.. the rod bearings still had the same part numbers.
I actually stubled across this random fact because my car is slowly becoming a little bastard child, since it's an early '95, and I am sticking in it a '98 420A out of an automatic Avenger (that was STOCK and had spun a rod bearing).

*Car BRAND ..... Eclipse *Model Year ... 99 GS *Total Mileage at time of incident ..... 23,000 *Total Mileage Turboed ......about 4,000 *PSI on Turbo ..... 10psi, only about 3 or 4 times *Fuel System Setup ..... Walbro Intank Fuel Pump *Internals.... Bone stock *Any timing tuning? .... No *What went wrong ..... I have no idea yet... I still have to bring it in. I'm waiting to get my Stock Headers and stock fuel pump from Wyatt cause I left them at his house when we installed it:P
But I had someone just look and listen to it and he said it sounds like it's one of the pistons...3 or 4. I'll let you know as soon as I bring it in.
Wish me luck.

I use to have a White 99 GS Sport with a Star Stage II Ball Bearing T3/T4 turbo...it was fun untill....well those who remember me know Oh Ya...this is what I have now... a 99' GSX...

Some crazy stuff going on here... Raizin seems to be the leader of the pack right now with blowing up 420As...
However, I am starting to see a funny trend with piston rings (gee... like we haven't already noticed!). It's also mostly (All except Raizin) with stock internals...
I'm starting to think that pistons, rings and rods should become part of the Stage II package. What's funny though is that I still haven't heard of anyone breaking a rod.... Looks like the rings/pistons always go first.
On a serisous note, maybe the engines CAN take 10+psi & 300+HP, but for sure they are not forgiving to tuning errors... One mistake and bam!
i don't think there is anything wrong with the pistons rings and rods for a stage II kit. Yes, they might be cheap, and wear out over time with the extra abuse, but all of these blown motors are caused by one thing. DETONATION!. well, except maybe for raizin cracked cam? WTF is up with that? anyway. keep enough fuel, these motors should be fine. even ask bill. His website praises these motors for their durability.
Always nice to hear nice comments!
