I do believe I have broke a ring land. Tonight when I was messing around with a porsche carrera s I heard a "pop." After that I parked the car. When I cranked the car up again it was idling like crap with the check engine light flashing. I drove it around and it felt a little low on power. However when I wasn't idling for a long time the check engine light didn't flash.

Me being the idiot I am decided to hit the nitrous just to see what would happen. When I hit the button it felt like I slammed on the brakes. I quickly let off and it keept running. Some guys following me said they saw a big flame come out of the exhaust (normal for my car when I hit the bottle) and then a huge cloud of black smoke.

I can now smell burning oil and have a horrible idle. I suppose it is time for a rebuild. I believe I might go with the 2.0l stroker kit coming out shortly from a unnamed source. I would like to have other peoples opinions or ideas about the rebuild. So any opinions or advice would be greatly accepted.

 

Sorry to hear that...at the same time....NOW YOU GET TO GO BIG!...LOL

The bottom end is strong...you really only need to replace your pistons...this based on what you said about the ring land....

honestly I would just say....what are you looking to do...how much power etc etc...figure that out first...it will answer alot of questions....

I personally do not think the 2.0 stroker is nessisary...there's 400 +hp to be made before that is nessisary...ofcourse if you're in there...I guess it can't hurt...LOL

 

I am looking to do 275whp without nitrous and then 450whp on spray. I don't see much need for spinning through 5th gear so 450whp on street tires is all I want.

I am trying to figure out how to put a Eaton M62 blower on it also.

 

how many miles on ur ride?

.......wow now u can start to make some real power both in tourque &hp
if u go stroker!!!!!!!!!

Carrera S huh!? wow what were u thinkin'?? :smile:

 

****how many miles on ur ride/mule******

450 on "street tyres is all" u will need to bang out a whole slew of sheit, on the street of course

 

Well as I am sure you know the only guys who have done it to date are Twincharged....and they already figured out the WHP limit of the stock pistons...and have pushed to 430WHP with pistons and everything else STOCK COMPONENTS...that's crazyness

if you can horse shoe that bigger SC....you may just be able to get that 275 with out a turbo....I'll be curious to see...

 

I have 53,000 on the car.

 

good luck with the rebuild, show some pics

 

well thats not to bad not to good but not bad, it lived a good while, NO!?

**how long did u have the juice in for?
keep postin' on ur progress and whos kit u use to rebuild

 

I'm sorry your engine is down. But as always, your pioneering spirit impresses me.

 

Sorry to hear about the damage, but glad to hear that you are rebuilding, "The Six Million Dollar Man" style.

Sorry to hear about it.

[shameless plug]
I have a complete 15K mile swap sitting here in my garage in Raleigh if you did more damage than you think.

Thanks for the replies guys I am going to try and do a compression test on the engine today. I am hoping that it was only one cylinder.

Also I am a little scared about what may have happened to the cylinder walls. If the ring land did in fact give out, and you drove it for 10-15 miles, would that not put a fairly large groove on the cylinder walls?

I think the stroker, if made of quality components, would be the smartest deal. You can run less boost and get more torque straight off. If you wanna make mad power and have longer life out of the motor, less boost is good of course! Anyways, hats off to you spillman! I remember thinking you were a crazy **** when you came on here talking about 21%, but you got 50k out of it and now you're ready and willing to fix the car. I'm very impressed that you're not moaning and stuff. Good man ! Good luck d00d. You better keep us in the know !

PS: Can you pm me about the stroker? I have some ideas myself !

 

I had about 20,000 miles with the nitrous on. I don't think the 23% caused this. The added boost was fine it was just the overall cylinder pressure from the 75 shot with 20lbs of boost. I had several people tell me the max for stock pistons is around 250whp. I guess I just got lucky and it lasted this long.

My supercharger is still working awesome. But it does have a healthy appetite for belts.

 

Spillman, in the interest of accuracy, the correct phrase is "blowed up."

Hope this turns out to be a great opportunity for you to go with the stroker. I'm with Ingsoc, would you pm me the details? I like your idea, and it does seem to be the best approach to improve low end torque (since you're gonna build it anyway). Good Luck!

 

have any of you 2L pundits ever looked at the crank and block and measured things?

I looked into upping the displacement and ruled it out; to pick up 100cc per cyliinder, you need to increase the stroke by 6.7cm. (there is only .3" between bores so it is not advisable to increase the bore, plus the wall to water jacket is thin, determined by unltrasonic testing of my block).

typically, one would use a crank with a modified pin (offset by 3.35cm). then you need a longer rod to clear the crank weights at BDC. that would also push the piston top up toward the head 3.35cm, so you need a piston with a pin closer to the crown. I'd like to see what kit might have solved these problems...

 

Well after I drove my blown MINI up which I had 249 whp, I had to drive it home for about 47 miles, I had no cylinder wall damage and now that I JUST got it back ,I need to break in the clutch, new pistons and rods. Don't forget to bore it 20 over so you can fit a forged piston in. Be sure to check out your clutch n pressure plates, after inspecting mine, I could see that 249 whp was too much for the stock pistons and clutch. The clutch looked like it was attacked by the kamakaze of WWII.

 

Ha ha! I thought the exact same thing when I saw the thread title.

 

I bet they are going to use a different shortblock.

The stock R/S ratio is great, I wouldn't stroke the motor at all. It'll choke the ports.

 

Pundits? D00d, calm down. I have not done any research, hence I ask for more information [the product is of course not public yet...]. What I did figure was that boring might be involved. Anyways, I remain interested, if only for the novelty of the matter.

 

Nice one Spillman hope it hasn't hurt those walls, I'm amazed you've lasted this long when you look what the timing does.

Were you using stock fuel pressure or regulating it down??

Any bits on the plugs???

Is your head ported??

Different Cam???

I wouldn't stroke it it'll just move the power band down, bu then again maybe thats what you want.

 

"pundit": "a porcus literarum, one more stocked with book lore than deep erudition."

make of this def what you will.

 

I am well aware of the definition. My understanding thereof led me to question your use of the word.
