My 01 civic with a K20A blew and there is a serious probs.

There are many members on Clubrsx.com that run 11:1 compression and turbo'd. Find out for sure it's just the piston and replace or pay to replace it. Not sure on estimate, but piston rings and pistons get blown all the time, replacing it shouldn't be expensive. The expensive part is buying the piston itself, and if you decide to go lower compression, to replace all 4 will be costly.

As for you joe, When you said you heard it crackling.... I seriously cringed.. That gave me the biggest cold chill. Detonation
I'd post up and find someone locally on ClubRSX, or a local board and find someone that knows how to tune with a k-pro... The people who tuned yours obviously do not have the slightest clue. I'd hate to have to see you go through this again.
Also, what octane gas are you running? With 7 lbs, and 11.5:1 comp........ shouldn't he be running 100+? This may be why you're detonating?

but on the other hand 7psi + 11.5 to 1 compresion = no no.

Rep Power: 326 Yeah I man I know the damage has been done, but why'd you buy the A motor if you were going to boost it? Too late now, but I'd buy some Arias pistons, and if you want more boost, get some upgraded forged rods and sleeve the block. You can make some serious power then.

Rep Power: 0 As someone said in an earlier post, RPM racing located in Huntington Station, NY is pretty sick. i live around the block and went down to the shop w/ my friend to see if they could figure out whats wrong with his AWE clutch(Audi a4 1.8t). They were awesome guys, the whole team came out to bs about what could be wrong, then they brought us into the shop to see one of their supercharged m5's. The car was ridiculous and they seemed to take pride in their work. So yea take it down there, i'm sure they will be able to help you out.

Rep Power: 374 Running Boost on a 11.5:1 compression is ok, its just going to need a lot of tuning. And the K-pro is great for that. What did you gap the spark plugs too? If I remember correctly, they have to be gapped to .32 for boost. I'm not 100% sure though. You can look it up on clubrsx though.

The K20 eats boost and asks for more. 7 PSI on the Cybernation kit runs 275 WHP & a 12.5 1/4 mile. Ummmm. I think it respons quite well.

From a member of ClubRSX..."Max boost is really depends on your setup and tunning. 5 pounds should be a walk in the park. Change your oil regularly and it your car maintained. High compression boost is not recomended if you want to boost more and have a reliable car you need to lower compression buy installing lower comp pistons. 9:1"
"most Honda motors tuned properly like an 11-11.5:1 static compression ratio for a safe but powerful amount of heat on premium octane gasoline. You can often go as high as 12.5:1 on a really well built motor with pump gas, but this takes $$ and a great understanding of the engine you're building."...directly from Compression 101: on www.speedupgrade.com

the second part is refering to n/a pretty much. so it doesn't apply.

Thanks for the info, no worries about throwing the thread around. Reguardless it's the shops fault. I think they forgot to put coolant in the motor. There was none in the radiator after the trouble suddenly happened.

The shop's replacing all of the damage correct? It better be perfect.
Thats what happens when you take a high compression engine, add a turbo and have a crappy shop tune it for you. With compression that high you have to be right on point with the tunning.I hope they at least had a dyno.

Rep Power: 0 I remember when this thread started. It was sort of hilarious. he was all excited about getting a turbo for his K20, and didnt want to listen about the compression. He boosted and blew, at least he sold it on Ebay for a good amount
