ARP flywheel bolts

[_Madman_]

I have ordered a fidanza flywheel for my car and while at it I also ordered flywheel bolts for it. Unfortunately they are longer than DSM stock ones so I'm wondering if it's a smart idea to use them. The bolts are these ones: EXTREME PSI : Your #1 Source for In Stock Performance Parts - ARP Pro-Series Flywheel Bolt Kit (8-pieces): Mitsubishi Eclipse 90-99

Plenty of people are using them (although most use Automatic OEM Flywheel bolts)
Especially people with aluminum flywheels, the theory is that the flywheel is thicker than stock, which you would need longer bolts to make sure you thread it far enough when you torque it down.

Trust me, nothings worse than having to pull your tranny back-to-back because your flywheel keeps getting loose...

You should also use an A/T spacer with the Fidanza flywheel so that the bolts don't dig into the flywheel itself. This will help to eat up some of that extra bolt length. It's also recommended to run a bottom tap through the holes before hand to make them longer. This will help with the extra length as well.

I've read these should work fine, but I went with OEM ones to be safe (I will be installing the same flywheel). Plus I think they were cheaper.

And remember to use red Loctite.

What sort of AT spacer? Is it really necessary?

It would also be a good idea to bottom tap the threads in the crank when using longer then stock flywheel bolts.

Not necessary... but its definetly dumb not to get one

This is what we're talking about
Forced Performance Turbochargers: DSM Aluminum Flywheel Hardware Kit

Well, I can't order that thing now because it's in USA, and shipping to here will cost me 200$-300$. Are there any alternatives?

The kit is only supposed to solve short bolt issues and to prevent bots from digging into aluminium, right?

 

[DSM_PWR]

....prevent bots from digging into aluminium, right?

Right thats what the spacer is for...

All it is, is an OEM Automatic Flywheel Bolt spacer, you can find them on any A/T dsms at local junkyards... or if you have a Mitsu dealer somwhere..

I really hope I will be able to find an old AT tranny laying somewhere.

Why would you use "red" loctite? So that when you or the next owner goes to install a new flywheel they cant get the bolts off. Sounds like a great idea.

Blue loctite "medium strength" will hold the bolts in place but allow one to remove them if/when needed.

 

[snowborder714]

I'd rather them not spin off at any point when the engine is running. I'll be removing mine in the next month or two to swap it to my other engine, but between a heat gun, impact gun, and breaker bar (with extension if necessary), I don't think I'll have any issues removing them.

I've always used red locktite on my flywheel bolts. You just have to grow a pair when getting it off, my 4ft breaker bar has a big pair.

RED LOCKTITE,

Better to be a pain in the ### to remove them, then to be a pain in the packet to replace the flywheel and/or the crack because of the strip threads.

 

[Ghost_92TSi]

Yea. I use red locktite on my crank pulley too had one back out on me before... never again.

 

[4ged4G63]

Sigh

Blue loctite is meant to hold bolts in place until YOU remove them. Red loctite is overkill and is typically recommended by bandwagoners who are inexperienced.

There is also people who safety wire their FW bolts, and I'm sure there is a reason for such strong precautions. A loose bolt there could have devastating results. I didn't go that far but I use red loctite 272 and never had a problem getting them loose. I've had my FW off 4 or 5 times in 5 years.

Sounds like an ok buy to me. If you question your purchase, ExPSI has good customer service, you can email or call them. They would be happy to assist you with the proper parts, i've ordered plenty from them. Its also nice to be able to log in your account with them to reference past invoices.
