I blew the ringlands up in my #3 cylinder. I didn't have any knocking or detonation. I'm just assuming it was damage done over the course of three turbos and beating up the motor for almost two years and I got some unexpected detonation.

Anyway I'm replacing the rods and pistons. I'm not sure about what else I would need and I have a few questions. So this is what I'm getting so far.

Wiseco 9.1:1 standard bore pistons with rings, Tuner Toys rods with ARP bolts, ACL rod bearings, Felpro head gasket.

Is there anything else I need?

I was looking at a lot of different companies rods and most of them come with ARP 8740 bolts. Some sites vary on their capability. Tuner Toys said the bolts can only handle 7-8000rpm but Manley says they 8740 bolts can handle 8000-9000. Has anyone used these?

 

sorry to ear bout your blow by probs but forged pistons & rods are much safer anyways.

I'd bore it .020 over & get a nice fresh hone job.
Wiseco Pistons - 400 bux Summit Racing
Eagle Rods with ARP bolts - 309 shipped (ebay distributor)

i guess that means your not going to be ready for the 15th?

 

yea definently get the over bore done, doesnt cost much and will prevent some other issues that might occure with std bore. Id say eagle rods should be all you need

 

I really can't afford an overbore right now. I can't even really afford the rods and pistons but I'm going to get them anyway. It figures that I worked last Sunday so I could have the 15th off and that same day I get the blow by.

Anyway, Eagle rods come with ARP 4870 bolts "Good for 7000-8000 RPM". So with the bolts stretch if I bring it up to 8k?

 

The bolts should be fine. Eagle always underrates their parts even though they have been tested well over their alleged strength threshold by thousands of high hp motors with minimal failures.

 

My initial plan was if the cylinders look pretty healthy I was just going to put the rods and pistons in with the block still in the engine bay.

If the cylinders were scored I would have no choice but to have it machined. And this would give me an excuse to paint my engine bay flat black like I've been wanting to for a long ass time.

It's not like I'm strapped for cash, I'm strapped for spending like 800$ all at once. Since June I've driven my car about two weeks tops. It's just a shitty feeling.

 

You should atleast get the cylinders honed, thats a big part of the engine break in is making sure you have a fresh hone. You can buy the tool to do it your self for pretty cheap, or a machine shop could probably do it for 50 bucks or so

 

It has to get better eventually. :hs:
I think you can borrow a hone from autozone.

 

and what if your cylinders are oblong in shape due to the stressed wear and you don't even know it. You will just blow more rings out. Have the block measure by a professional before you make an expensive assumption that it's ok just be cause it looks it!

 

Well, would a .020 overbore do much for the displacement at all other than get rid of some scoring and hot spots? I'd deffinetly find the money for the overbore if they hot tanked the motor for free. I have OCD so dirty motors make me twitch.

Yeah. It's probably the effect of having three different turbos on the car over a year long period with fuck up after fuck up, the car being in an accident, and then a quick burst of detonation.

I can't afford diagnostics and measurments, balancing, all the bells and whistles.h:
