Is this 6 bolt reliable?

[95burgundyesi]

Okay so im kind of stuck in a weird spot. I have a choice between a stock 7 bolt that has 130k on it and has never seen anything but stock boost from a t-25, or i can have a 91 6 bolt with 100k on it which also never saw mods. the 7 bolt is already in ,and the car is stock. Has a compression of 160 straight across. The 6 bolt compression is unknown but i am told ran flawlessly.

I was told that a cold compression test will read lower numbers than a hot one, like 20 below what it would be if it were hot. Since the 6 bolt isnt attached to a car is there any way to get an accurate reading? Or should i just not bother?

I plan on eventually having a 16g with some good bolt ons, so i know the 7 bolt is getting a lot of miles on it. Does anyone have any suggestions?

Depending on what kind of mods were done....the 6 bolt would probably have been taken care of just a little bit better. If you've got a stock 7 bolt with good compression whats your issue? Just leave it in there and build the 6 bolt for when it blows or starts losing compression...
Is that what you're asking?

Get the 6 bolt.

1. Lower miles
2. Less likely to crank walk
3. Better platforom to build on

Well for 250 bucks i can have the 6 bolt put in. They both never saw anything over stock boost. The 7 bolt is in a 95 tsi awd, and the 6 bolt came from a fwd laser. No signs of walk and im not concerned because its got 130k and is still fine.

I guess i was asking if it would be worth it to throw in the 6 bolt. They both have their milage on them so idk guess i was woundering if anyone thought i should leave it or swap it. for 250 bucks, isnt that a good price to get a 6 bolt? The only thing that scares me a bit is that he said he can't get a compression reading like it would be if it was warm.

If its got 140k, the chances of it C/W is ridiculously low.

You dont know its got lower miles, judging that 6 bolts have been around longer, i'd guess that at an AVERAGE of 10k a year the YOUNGEST that engine can be is 150k+....

Yes its a better platform by only 50-100 hp...He's still on a 16g so he shouldn't have to worry about snapping the 2g rods anytime soon...

I'm not trying to put your post down but he's obviously not building a 10 second car...
The ONLY reason i'm for the 7 bolt at this point is because its already in the car...

Yeah i just thought for 250 bucks im getting a 6 bolt and installed why not but i thought i would check first. Are 6 bolts always this cheap? i appreciate the with-in minutes responses.

Are you playing on puttin it in your n\t?

 

[95burgundyesi]

No, this is a completely different car. 95 tsi awd

Drive the wheels off the 7-bolt.... when you blow it up, drop in the 6-bolt that you have been patiently building
