Re: My 96 Z28 - Engine rebuild - problems

I have one, but I also built and and tuned my own engine, and it probably makes upwards of 700 hp, and if you don't want to trust our advice then no one is going to waste any more time trying to help you. I understand that you don't have many choices in what to do and need to get your car going. Just remember, my car isn't the one that is in the shop again, unusable, runs like crap, leaks, and smells like fuel.

I will remember that well, thanks for rubbing it in.... kicking me when I'm down.
I'm happy you have a 700hp engine that you built and tuned yourself and it runs great.

That's about as helpful as the guy who said "Eeek, talk about a waste of money."
Like I knew all this would be a waste.
I will continue to fly by the seat of my pants as I have been. I need help here local and as of yet I haven't found it, as in a repair shop that is honest and will do and say the right thing.

Re: My 96 Z28 - Engine rebuild - problems

I agree that you could really use some local help. It is also understandable that a manufacturer is going to tell you "Yeah, that TB will work on your car" and then not provide adequate instructions on how to make it actually work (things that people that have actually installed them know you have to do).

Not kicking a person that is down, but you made some really bad decisions and now are mostly stuck (because of the warranty) with the people that obviously don't know much about your car, either. Eventually, they will likely grow tired of trying to make it work, but I hope they can get some help, too.

Maybe you could try some of the local forums. Houston is a big place and I would imagine there are some folks in the area that could help.

Re: My 96 Z28 - Engine rebuild - problems

Just to give you some idea of why we say the things we do.

The reason the 58mm TB will blow up the tranny is line pressure is scaled off a few criteria including throttle position. The 58mm TB lets in more air for a given throttle position. The line pressure needs to be raised to account for that extra power or it slips the clutches too much and wears them out.

The decision I made to get the engine rebuilt was based on advice by one of the most honest and trustworthy mechanics my wife and I have dealt with. But, I kinda think he had a little bit of "I don't want to work on this Camaro" mixed in with the honesty, which is why he pushed us toward the rebuilt engine idea. Yep, of course the decisions I made to get the engine shop to install the cam, throttle body and ported intake was all my idea, along with research I did on the internet. Guess you can't believe everything you read on the internet..... or maybe most of what you read.

Maybe you try some of the local forums. Houston is a big place and I would imagine there are some folks in the area that could help.
Don't believe there are any Camaro forums in Houston but I'm sure there are mechanics or wannabe's that know a lot about Camaros and LT1's.

I actually like this forum and I have found some good info here that has helped me, but as I said above, you can't believe everything you read on the internet, but here....... you can probably believe most things.
One thing though, I don't like braggards, those who like to talk about how great they are..... I don't listen to them much at all.

I guess I'll be reporting back at some point here to let you know if the things some of you said will happen with the TB and cam, have happened. You can all say I told you so if and when it happens.........

What line pressure?


And to think, I could have bought a brand new crate engine for the money I've spent on the stinking rebuild........

It is the hydraulic pressure the tranny applies to the clutches, not enough pressure means slipping, wear, heat and destruction.

Far as the "crate motor" some of the popular stuff is JUNK. I mean the biggest LT1 crate engine builder in the country sells stuff that makes mediocre power and then needs rebuilding at 5-8K miles. I would take a junkyard engine first, actually that is what I did.

Re: My 96 Z28 - Engine rebuild - problems

Houston has all kinds of stuff. I have Fbody clubs in VANCOUVER WASHINGTON. There is definitely one in houston. Im sure they have a website.

Do yourself a favor and sell the damn throttle body and buy valve springs.

Stock throttle body will take but 10 minutes to put back on. No big deal.

There is a regional forum section here on this site:
West South Central - CamaroZ28.Com Message Board

Maybe you can wake someone up, there.

You can believe some things you read on the internet, but it can be difficult figuring out what is the correct information.

Re: My 96 Z28 - Engine rebuild - problems

...and in this case you have received TONS of correct information while the INCORRECT information is what your so-called "certified" mechanics say.

We're offering you help with decisions that you can make on your own. The guys who have posted in this thread have been doing this for YEARS and since you admit that you're a bit green I suggest you take our opinions a bit more seriously.

Re: My 96 Z28 - Engine rebuild - problems

This thread is really going nowhere.... lot's of good advice and help, and it's all being rejected. Then the people who try to help are put down as "braggards" (sic) because they offer hard data/examples of what the throttle body is useful for, and what it takes to make it useful.

Always amazes me when people look for help AFTER they make all their decisions, find out that they ended up with a mess, and then get angry at the people who offer them good advice, just because it's blunt and direct and not what they want to hear.

Ok.... I admit, the voice of reason is speaking to me after some of the advice you guys have given, I just don't need the smart a** remarks basically telling me how stupid I am for doing what I did. I get it, I wouldn't have came here if I didn't think I could get some good advise, but I would be more apt to take your advice if you'd be a little bit nicer.

I found a guy on the internet that programs LT1 PCM's and he told me that the cam and 58mm TB would be ok with a retune and some mods to the TB.

Right now the engine shop is telling me 2 of the fuel injectors that they rebuilt went bad and they are replacing them. Still leaking oil, so I will see what happens Monday. Should I tell them to put the stock TB back on now or leave it on and get a retune done?
