Eagle Aftermarket Rods for 2g

Onefast99gsx · 10-23-2005

Hi guys-

Im kinda worried about the stock 2g rods of mine letting lose on me at some point. I figure in running 12.0's, i'm probably running in the 400HP range. I'm doing some research on the Eagle rods for the 2g motors. Can you tell me if these rods will work with the stock 2g pistons that are in my motor?

On Eagles website, it says something that you must use the 1990-1992 bearings.

I don't care to do a 6-bolt swap. For the 2-4 times i goto the track a year and boost up I don't think it's worth it and i'm not gonna spend as much money on my car this winter as I did last. I just wanna make what I have currently, reliable. So I would like to put Eagle rods in, aftermarket valve springs & Ti Retainers. I would be doing this with the motor/crank still in the car. I would hone and re-ring at the same time.

Thanks for any suggestions on these Eagle Rods.

you should have you car checked for crankwalk first to see if it is even worth putting money into the motor. I wouldn't put the rods in there even if I was making 400whp on a stock block. Barton put down 450 on his car with 7 bolt rods. I think you would be fine if you just stick with the 50 trim.

I have heard that eagle rods arent that much better, but that could just be a bad opinion from someone

Thats a "bad opinion".

**JET** · 10-23-2005

Yep, bad opinion. Also, the stock rods should be fine unless you start to detonate. I would just stick with them.

Thanks for your opinion you guys. Everything is up in the air right now. I just wanted to start thinking about this stuff now in case I wanted to do something over the winter. With working on a down payment for a house a 6 bolt swap is not in the picture for a year or two out. I'll have to stick to what i have and hope it's fine. Shifting to 4th before the traps is gonna be a must. I stayed in it too long yesterday as far as going a little over-board with the rpms.

Too bad a guy couldn't do a budget route and use 1g big rods in a 2g motor. The crank journals i'm sure are different sized though.

You do know that you can put 1g big rods in there right? Just have to do a few little mods to the rods and you can put them in.

Ju-on- Dam, that's perfect for a guy that's on a budget. Thanks. My brother just happens to be a professional machinst who runs/programs CNC mills and lathes.

By the looks of it, you have to change the thickness of the wrist pin end to 1.040". I don't know what they mean by that other dimension that's pointing to the journal end of the rod. 1.8897" to 1.8905". What are they referring to? Changing the thickness of that end like you do to the wrist pin end or is that the diameter of the journal itself? What does that measurement referring to??

Who's got a set of 1g "Big Rods" for sale ???

Isn't the 1G 6 bolt rod modification Brandon linked only valid for using the 1G rod/2G piston combo with a 6 bolt crank & bearings? I've never heard of anyone using 1G 6 bolt rods with a 2G crank & bearings.

**Shane@DBPerformance** · 10-23-2005

Yea, it is meant for putting 2G pistons in a 6-bolt block.

Onefast99gsx · 10-23-2005

Dam.. sounded good though and a cheap upgrade.

Onefast99gsx · 10-23-2005

For anyone who reads this. I'm getting the specs for machining the pistons to work with aftermarket 2g rods. Car has around 90k miles. During last winter, i extensively checked for any sign of crankwalk. I could not get any dial indicator movement whatsoever. I'm not saying it still can't happen. "knock on wood" I'm just saying that it hasn't. For $300 Eagle rods, I think it would be worth the extra insurance.

Leave the stockers and save up for a 6bolt.

CDeutsch · 10-25-2005

Don't fix it if it isn't broken. Taking apart the motor opens it up for problems/mistakes on disassembly/assembly and it's not worth the risk to just do the rods (especially on a 7bolt). If the motor is working keep using it and build a second one (6 bolt).

Onefast99gsx · 10-25-2005

That's probably my plan. I'll just wait and while i wait, hope nothing ever happens. Can anyone give me some input on this. Let's say i wanted to build up a 6 bolt. I'm gonna use my 2g head because it's ported and also because i have a 2g Magnus intake. Let's assume i had a decent 6 bolt bottom end from the fly wheel to the timing belt cover. I would use the stock 6 bolt big rods but get 2g 8.5:1 pistons.

What would this project cost roughly so i kinda know what to prepare for?

- 2g pistons .020 over
- .020 over bore job
- all new crank bearings, shortblock gaskets, etc.
- bal shaft eliminator kit
- flywheel resurfacing
- machine shop assembly labor time (for the short block)

I just want a ball park figure on what it would cost to rebuild the bottom end and then use my 2g head. If i got a shortblock for roughly $500(or whatever), would the above rebuild be another $500 for a total of $1,000(entire project) or am i too low with my estimate?

Hey tim

I made 400/368 with the scm61 and cams. Stock manifold and TB. Just be conservative with timing and you should be fine. I am on a mision to take out Brian on the stock motor. I wouldn't mind doing more, but my clutch won't like it. OEM clutch baby. Your guess is as good as mine to why it still lives.

Hey Nate-

Welcome to the board. You'll like it here much better than talk & tunerz. Full of a pretty knowledged DSMers. Alot of HP seems to come out of the Minn. group.
