Kinda like how I laughed at the local Chev. dealer upon seeing that the MSRP on a Cobalt SS was $30k aprox five years ago(!) - then again in the 2009 model year there was also the SRT4 fighting for a share of the domestic sport compact market ~ right now the Focus ST has no competition!

 

That's just the price of cars these days. It's not just sport compacts. Everything is 5k more then it was 5 years ago. Go shop for a new mustang 5.0 or a camaro ss.
Good luck getting into a new one for less then 45k with next to no options above base.

That's why financing is getting longer and intrest rates are getting lower.

 

the msrp for mine with every option was 25k. I was very surprised, it was a few hundred more than it was in the states. after all said and done with taxes and all I payed like 27. but it was my first ever new car and one id been wanting for a few years so I did it. probably wouldn't do it again though, would have to be much better car if I would

 

Ya I agree. He makes good points but is coming across as a know it all. If I snap a rod in my Gen 3 I will burn my car to the ground. But really no one has any solid info there, it's just **** getting thrown at a wall and hoping it sticks. Don't think I can make enough power on 91 to see any issues if there were any but still not something I wanted to read if it is in fact true. Why they would even change the rod from the LNF is beyond me.

cause they want u to brake so u bring it to them to fix.

 

it's all about repeat business

 

If that was the case then they wouldn't have reenforced the top of the cylinder in the 3rd gen motor

 

Just means something a little less major is the weakest link lol

 

Breaking a sleeve or throwing a rod through the block would be on the same playing field I think lol

 

GMtech is not a GM spokesperson. He just happens to work for GM, but is not a voice for them. He is actually very knowledgeable and has contributed a lot of information over the years. He is also really hard headed and comes off with an attacking attitude almost all the time. He is hard to get along with but has posted a lot of good information in the past. He also has always seemed to have a personal vendetta with ZZP. Take it with a grain of salt.

 

In other news

Track Rental

 

well I would really like to know what his malfunction is. what makes him hate zzp. he calls us all morons basically because of one engine that failed with a zzp tune. there are tons of other engines that are still going strong with tunes like that. so ya id seriously like to know why he hates them so much, did they look at him wrong at some point, or tell him he was wrong? he seems like that type who would hate someone who didn't agree with him

 

You renting the track for some test and tune? Lol

 

Lol. Didn't know it could be rented until now. That would make for a fun day. Specially the road course

 

Oh ya. TTI rented it for a day a short while back and had a drift day.

 

Wow only $500 a day I'd even be interested in that.

 

Holy **** that's cheap for a track with all those different events!

 

Well tore the ZZP HE out so I am running on stock HE and stock exhaust mani now, might as well put in stock injectors, pully and tune and see if the knock goes away.

 

Wow sounds like your guys gas sucks there Blue is having issues too.

 

Oh no no no its not gas with me. Heres my story grab some popcorn and enjoy

I have been fighting a knock issue for the past couple years. I have a 07 Cobalt SS/SC with the 2L LSJ. My Mods are:

Performance Mods
2.8 Pulley
60# Injectors
ZZP S3 Heat Exchanger
CCSS3 HPT Tune (currently in progress & on hold til knock issue fixed)
K&N Air Filter
Bad Mab Header

Now that your up to speed on my mods. The issue, in a nutshell when going full throttle over 5000 RPM in 3rd gear I get knock retard of up to 12*. Also noticed is when doing a pull during shift at each shift my kr spikes 10* then back to 0 utill it hits 6K rpm when it hits 12* +/- 5*

What I have attempted to try to correct it:

1. Working with my tuner we have reduced timing from 22* down to 15* with no change noticed at all, same amount of KR still present.
2. I have had the fuel injectors sent out for test and repair, they were apparantly a "horrible spray pattern" as the shop said so they were repaired and retested and all is good with them
3. changed the fuel filter
4. change sparkplugs to BKR7EIX
5. looked for air leaks and found and fixed multiple areas of leaks.
6. looked for loose items that could vibrate against engine found and fixed multiple items there too
7. Removed Cams and checked all valve springs and lash adjusters all checked out ok
8. compression test OK
9. Fuel pressure test OK
10. Will be doing a leakdown test as soon a i can get my hands on a leakdown tester.
11. went to change the S/C oil this summer and there was no oil in it so trying to get my hand s on a spare M62 to see if that helps if so I will rebuild mine.

 

Find where it's cracked?

 

No gonna look at it tonight and see. If I cant find the crack I may get it pressure tested.

 

You were never anywhere near 22* or your motor would have exploded. But your current tune only has like 10* on top. But yes, dropping timing makes no change in the kr the motor is getting.

 

I was hungover when I took it off. so as soon as I was done I went back to bed lol.

 

That was a cut and paste from a thread a while ago when i was more dazed and confused as to what was going on. I am better now.
