That sucks that your brand new motor failed!! But that's part of the learning curve. Same thing happened
to me, put too much timing by mistake and killed a rod bearing
But I'm glad you are enjoying your car! I'm going to the track this coming month to
shake down the car. I'll make sure I can get some in car footage.

Keep up the good work!!



You must be referring to my rebuilt 2.8. That failure convinced me to go with the ecotec. I am on my second 2.2 but the first one did not fail, I managed to screw it up while taking it apart to put better pistons and rods in. I had about 60000 km on the first ecotec IIRC. I sank over 2000.00 in to my 2.8 and it lasted 600 km. It ate a lifter and a cam lobe, it was very disappointing. In car footage is great. I have a nice GoPro but I forgot to take it to the track the one time I went this year.

I did not know that!! But I was looking at another thread and somehow I confused the threads!!:

My engine is already in the car and running! I'm also working on a set of aluminium heads and for it
and my goal is 300WHP

Hey, can you let me know what are the part #'s of the coilovers? You can PM me so I don't jack your nice thread

That is a good question . I thought I had put the part #s in the thread somewhere but I could not find it. So I looked them up on Summit racing's website :
Fronts - QA-1 Proma Star DS 402
Rears- QA-1 Proma Star DD 402
These are available in different lengths, mounting methods and any 9-10" 2.5" ID spring that you want (springs sold separate). So go through the catalogue before you order. Only thing I would have done different is put a bearing on the top mount and get DD 402 (double adjustable) for the fronts as well.

Thank you very much!!

Got the new front tires put on today and I am really liking these tires. Turning effort is lower and they are really quiet , surprizing because a lot of reviewers thought they were on the noisy side. And really grippy. Not many miles on yet but hope to put a bunch of miles on over the next couple of weeks and then time for it to be put away till next May.

My old front tires, you can see the wear line is still on the middle:

On the way back from the allignment shop I was getting a lot of road noise that I thought was because of my new front UCA bushings. A lot of noise. Put the new front tires on and the noise disappeared. Here is a pic of a Del-A-Lum bushing. I had the local machine shop turn the step off the AL centre part and make a holder out of DOM tube. I can weld an A arm to the holder tube. These may eventually become part of my rear LCA's.

I have been looking at different weights of Fieros on other threads and got me wondering how much my car does weigh now. In the immediate area the only place I can do that is the dump. They have a commercial truck scale, so I took it there. With almost a full tank of gas and me out of the car it now weighs 2746 lbs. The car does not have a spare tire or AC compressor. That is 44 lbs lighter than the last time it was weighed. Credit goes to my lighter exhaust, lighter rear brakes and lighter rear suspension. So all that weight has come off the back of the car. My new front/rear weight ratio is 55.25% rear and 44.75% front.

The car comes off the road on Halloween. So I am not going to do any more suspension work till after that but I am going to do some tuning. During my quest for more revs back in the spring I changed a few things on the tune. Once I got it to rev to 7000 (by putting on a 2.5 " exhaust) I left the tune alone to conentrate on the suspension. Now I am back to tuning. I haven't run a scan since finding the problem area in the spring so I ran one today to see what I should do. Keep in mind there are many short comings of the ECM that the2004 2.2 ecotec cavalier uses. MAP only, you cannot change the base AFR and there are a limited number of spark and fuel tables to work with. But it does monitor all parameters at some ridiculous high speed so it does a very good job protecting my engine from my inadequate tuning abilities. So I went out and ran a scan to see where I am at and for the most part it looked good. The only problem I see is too much knock reduction (KR) at full boost and full throttle. Two things that should help this are just reducing the timing tables or increasing the AFR table for Power Enrich (PE). Since reducing your timing tables is a good way to reduce your power levels, I am going to increase the AFR in PE to 11 across the board. It was at 12 so hopefully this will make a difference. After I do this and run a scan, I am going to increase the water meth spray to see if that improves it any as well. And I did crank the boost up before I did the scan. Peaking out at 13 PSI now. The goal is to run a max of 15 PSI if possible.

If you are using Water Meth close your spark plug gap until the engine revs with no misfire. I personally tune with less timing and less fuel and that always gives you more power.
But if you add Water Injection to the equation then every changes. Through years of testing (I did some testing for Snow Performance) I found out that you must close your plug gaps once you start to inject water in the combustion chamber. Once you get that dialed in, the possibilities are endless.

No problems with misfire probably because a turbo engine runs hotter than a NA engine. I will be adding the timing back in that I took out while I was having the problems caused by the 2" exhaust. I also need to go in to the HP tuners site on the tune repository and see what new tricks people have come up with. But I think I am almost ready for a reflash.
