That was exactly my point.

Going to the junkyard Saturday......

I sent the same info to Jake. Haven't heard back yet (understandably...he's busy)...but if this is promising, it could be an easy solution to a number of engine combinations.

I have already done it... And it will work, BUT according to the rod you use the bearing locating tang can be an issue...

Get the parts and then we can compare notes.

Fair enough, Jake.
The bearings are on the way. I'm still trying to locate a 2L rod for comparison and fitment. Methinks Don is looking at the donor rods, too maybe not a bad idea since they are only 0.002" wider than the stock 2L rod; but they are bloody long, so maybe Don will move his powerband up past 8500 . However, I think they may be of powdered-metal construction. I'll have to look into that...(or Don will )

Bearing material is CL-66, same as standard Chebbie bearings.
THose rods are about the same weight as type 4 rods also.....750gs.


I'm looking at info now..........


5.9", Hmmmm. That still would put me a 1.87 rod ratio, still too high
for my needs.

My crank isn't nitrided(old DPR product), so I'm not looking at turning
past 6500............OK, maybe 6800! Still haven't ordered the revlimiter.


I want it to suck on the heads from the git-go and run out of steam
around that limit.

I'm looking fer 11 to 11.5 CR and running premo street gas.


Go ahead, tell me it can't be done......

But that's stock. Both Clevite and Sealed Power make replacement bearings (which would be the same as Chebbie replacement bearings ). I don't know the reputation of the Fed. Mogul/Sealed Power parts, but I'd imagine any tri-metal bearing is a step-up.

BTW, these engines regularly see 300-400-500+ HP by crazy guys who don't mind turning up the boost. Even in stock form, these engines produced twice the power of the VW 2L.

I'm taking the 2316's heads to Len's Dad at lunch tomorrow.
HE owns an import parts/repair/machine shop and he can look
the bearings up fer me.

I've put this off too long as it is, I'm ready to TURN this thang ON!
It's gonna run with what I gots fer now.

Hey guys, I am back from vacation! I was riding around in the island of St. Marteen in a Pinzgauer! I'll send Jake a pic of a caravan. Stripped66, call me, I do have several 2.0 rod sets at home.

Yeah, send me those pics! I knew someone somewhere had to be using Pinz for touring purposes! Its the ultimate 4X4!

Okay Jake...let's compare notes

Bearing width is fine. Bearing outer diameter can be dealt with. Thanks for the heads up about the tangs Seriously, though...nothing a spot of weld prior to reboring the big-end can't fix. The new grooves can be hand-filed if careful.

So...from what I've seen and measured, if anybody running a stock 71mm crank and 2L rods wanted a better bearing set, they could do it with minor mods to the rods.

Since I'm not so much interested in the 2L rods as they are a tad short for my needs, I'm still looking at a few different rod options. I'll talk more the more I know more. mmm'K? I will go on the record to say that I WILL use these bearings.

any updates Jason?

Whats the pin diameter on these LONG Mystery Rods ?

They sound like either the Mitsu 3000GT rods or the early90s 3SGTE , celica and MR2 turbo , one variant came with a blower?.

The factory rods can have the bolts flipped, and both original motors handled tons of boost fine.

They're too long for anything I'd ever do.

OTOH, at 2", the cosworth rods at 5.7" are wide enough and so on... if you can get the bolt heads to clear (no idea what strokes would work)

(Oddly Jakes shadow told me about those awhile back when he still dared to appear here, he acted like it was a huge secret too... If you look at rod size charts, they're te only ones that work out, not bloody rocket science.)

See the "spilling the beans" thread.

IIRC, the Mitsu 3000gt rods are too narrow. And the 3SGTE engine was turbocharged in both the MR2 and the Celica All-Trac (the latter relatively rare in North America, unfortunately)...BTW, 5.4" Toyota rod is hardly too long
