No wonder people here rarely do anything cool and creative...you guys only know how to spend $30K on setups that other people build for you. Wow...

IF YOU DON'T HAVE AN ANSWER FOR MY QUESTION, PLEASE DON'T POST.

EDIT: I'm not trying to generalize because some poeple have been very helpful but most have just been a pain in the azz.
You are just too much.

I have done more innovative and creative things with my Z in my garage with my own hands then you have even dreamed of. If you think you are being innovative by purchasing used pistons and using the Pathfinder block your dreaming. You may be taking risks that are near pointless and will show little gain in the end, but you are not being an innovator like you are making yourself out to be.

You are absolutely right, there a number of people here who whip out their check book and take their cars to a shop. Of those people who pay "$30K", 4 out of 5 of them have blown their motors the first time just like you or built their motors once, twice, some even three times and they just want it to be over.

You get criticized because you could have just as easily emailed or called CP or talked with your machine shop.

+1 for thinking out of the box.. if you can afford it.

+1 on doing it right at the first time..

GT-ER I'm in the same shoes as you, but I wouldn't risk the used parts, only because I don't wan't the engine to die another time ....

I hope it all goes well for you in the end, with this "different" build.
I'm deffinately looking forward for the results

First, I wasn't talking about you. You fall into the exception I posted.

Second, I never said I was an innovator...I said that people criticizing like crazy are the reason why there are very few on this forum. All we normally see here are just people taking out their check books and dumping money on "proven" builds just to have them blow up anyways. Which is pretty sad imo. If mine were to blow up at least it would be 100% my fault and I may actually even learn something from it.

Third...I asked a simple question that could have been answered in a single post. It was late and I was wondering if anyone simply had what I was looking for. But you know what? You're right...next time I will DEFINITELY ask the manufacturer even if they take forever to answer me, this is just too much BS for such a simple question.

OP-I am tired of your godd@mn stupidity.

It all started with the "I have a problem with my car" thread, and people told you to not drive it.

Instead you do drive, rev it, and the **** blows up. That was d!ckhead move #1, which has since snowballed from there.

Since then you have seemingly started a thread for every question, issue or update about your car. Call the piston manufacturer and ask them, and avoid the constructive criticism if you dont fawking want it.

Now you have knowledgable members giving you good advice and you just brush it off.

Im sick of seeing your threads, your posts, and your complete lack of understanding.

Your car has always been weak compared to others, and if you build this setup, it will continue to be weak-fawking-sauce.

It would seem to me that if you want technical information about a piston, you would ask 1. the machinist who is going to have to hone your block for that piston (as he has probably worked with CP before and has a preference for clearances) or 2. the people who make the piston in the first place. I'm all for posting tech questions, but this thread wasn't needed in the first place IMHO. If you are going to post about what you're doing, expect reviews of it. If you don't want the reviews, don't tell people what you're doing with your car, and then it's left up to you to decide, and make it work.

Thinking outside of the box purely for the sake of it is one thing. Thinking outside of the box because you have figured out the better mousetrap is a different ball of wax altogether, and plenty here have done that, both on their own and through the assistance of a shop (or more than 1 shop). Just because someone chooses to let a shop handle their build does not make the build less-worthy than the person who chooses to do it themselves...and vice versa. Everyone gets to choose their own path.


Hopefully it all works out the way you planned, best of luck

Says the person who clearly falls into the category of the people I was criticizing. Maybe Forged can build my setup here in PR and I can be as cool as you are? LOL.

I just asked if anyone knew what tolerance CP asks for...that's it. No opinions nor criticism was needed to answer that very basic question.

Did I ask for opinions on my pistons? Did I ask what people thought I should do with my setup? NO....I just asked for a number that could have been answered in ONE post. No opinions needed.

You have no clue what you are talking about....

Your right.. you didn't. However, there are multiple instances where you have asked opinions in other threads and ignored the advice of people who have gone done the same road before.

I have done more in this community, shared my experiences, and helped others much more than you will ever with that "ground breaking" craptastic build you have planned.

Forged? Welcome to 2007

edit-Id be upset if I had a Vortech setup that ran 13.5 too, my NA setup from 6 years ago would have smacked you off the track.

You never took advice in that drag thread (lose the 20" wheels) and like has been mentioned you have failed numerous other times as well. We will not give you reassurance that your plans are good to go if in fact they arent. If you need that go get it from your boyfriend.

The truth hurts, I know.

Easy now. I ran 13.8@ 110 on my TN setup. But that was in the middle of summer on a non preped tack with a 2.6 60ft. I had better traction launching on the street Lol

I mentioned 11 to 1, with 10 psi on E85 the other week. No one answered.

this is interesting to me as I have 11:1 weisco pistons for my NA build and was thinking of running boost later on when I get beat down by low NA power.

e85 + high CR = good power?

always heard you wanted lower CR when boosting. got a link on this so I might learn?

bad Idea for a T or TT setup, but good idea if you plan on staying on a SC with a Maximum of 17psi~

edit: don't know what the exact maximum would be, think it also depends on the rods and @ which rpm range the XXpsi comes in and so much more any help?

hmmm whats the difference? I thought boost was boost... just superchargers were more linear power compared to turbos which create a given boost based on size and spool time

why is high CR good for superchargers and bad for turbos... now I'm confused.

the higher the boost, the lower the rpm, the lower CR you want.

Since turbos make full boost usually under 4000 rpms, thats why you want lower CR.

Since SC'rs make full boost at redline, you can run higher/stock compression.

Lower CR lets you run more boost before you start to detonate. But since SC'rs dont make alot of boost outside high rpms, you can bump the compression to give the engine better response at the lower rpms

Thats why JetMech said the low CR supercharged car he drove was junk. Lower compression kills power outside boost and since superchargers have to rev high to make boost its a bad combo.
