    2G Is this a problem?

    Put some grease on a detail file and knock down any high spots. Then wipe clean to make sure you get all the grease.

    1G Cracked bell housing after trans and clutch replacement. How bad does it look?

    Looks like they tightened the trans bolts with the water pipe tab flipped down, or a wire stuck between.It can be welded. I always bolt them to a junk block to weld them, or they warp.

    2G Need ideas for AFPR mounting location.

    I like using 1” wide aluminum strips for making brackets. If you don’t weld, just cut it to length, drill holes, and bend it to fit.

    Resolved Weird sound when coasting.. help

    A solid clutch disk and lightweight flywheel will usually cause a strange sound on decel as well.

    Can't ACL do anything right: a rant

    The aluminum bearings will start to delaminate around 125hp per cylinder. Right around 15-25* after vertical they’ll start losing pieces of bearing.

    I’ve used clevite for many 6g72 builds. They’re always in spec.

    Can't ACL do anything right: a rant

    Every box of Acl alumiglide bearings I’ve ever opened had metal shavings in them.They’ve also had qc issues with 6g72 bearings (sizing). I use king in everything.

    Manley H Beams Vs Eagle H Beams

    I maxed out a 800hp turbo with eagles.

    Manley H Beams Vs Eagle H Beams

    The exhaust stroke is hardest. Positive pressure air is blowing into the cylinder pushing the piston down in a turbo application. Even the exhaust stroke gets padded by exhaust back pressure.

    Manley H Beams Vs Eagle H Beams

    Look back through the interwebs and look for failed 4g rods. They’re all bent or broken in compression. They never pull the caps off.

    Manley H Beams Vs Eagle H Beams

    They appear to be the same rods, with upgraded bolts. The weight is the same with both. If that’s so, theyre a waste of money for our application.

    Resolved Is this a 7 bolt 4g63t crankshaft?

    Not a 4g63 crank, it has a flat on the snout to drive the oil pump.

    Resolved Balance shaft bearings question

    There is no thrust bearing on the shaft. That’s the only thing that takes an axial load. A stub shaft is just as likely to move axially as a whole shaft.We ran stub shafts in 1300+ hp builds with a fuel pump driven off the timing belt. Zero pump issues.

    Resolved Kiggly main girdle thickness?

    We used oem stub shafts without issue. This is with a fuel pump driven off the belt as well.

    I thought it was quoted as a reply, but I guess not.Either a forum bug with close together posts from the same person, or I forgot.

    Resolved Kiggly main girdle thickness?

    The upgraded rod bolts are a waste of money in a forced induction setup. We ran 7’s with arp 2000’s and never had a bottom end failure during the whole program. We went from 10’s to 7’s with hundreds of passes over 3 years.In forced induction there is exhaust back pressure pushing down on the...

    F5M33 rebuild. Does this look right to you?

    The sub gear reduces gear noise and vibration. It’s a basically a rotational damper. The gear it’s on can’t really chatter back and forth.

    2G Cryo treating gears how much more HP can they handle?

    I’ve broken at least 20 stock gear transmissions, taken them apart and saw how they failed. Fwiw I still have less than a full dog box costs spent on trans parts.3rd of 4th always break at the onset of peak torque, whether you roll in, or flat shift. Flat shifting makes the hit even harder.
  20. donniekak

    2G Cryo treating gears how much more HP can they handle?

    Breaking third gear from a roll you started at 3,500 rpm’s has nothing to do with clutch engagement.Flat shifting into 3rd or 4th is a nono, no matter the clutch.

    2G Cryo treating gears how much more HP can they handle?

    I had a big name trans shop tell me to my face that all the treatments people do to stock Dsm gears are a waste of money. That the reason they offer them is customer demand.Our 3rd and 4th gears have the teeth ripped off the base circle, there’s not really much you can do about that.

    Late Manley Pistons PTW Clearance

    I would never buy stock bore pistons for a block I haven’t first honed and measured myself, or by a shop I trust.It may be surface rust that will clean up with another .001” or so taken out. Those pistons will work ok out to about .0055” clearance for a street car.It needs to be honed with a...

    Late Manley Pistons PTW Clearance

    Those marks look like corrosion. Either from sitting with water in the cylinders or cracks in the cylinder wall. I highly doubt a stock bore block cracked with a 14b, it’s probably going to need to go .010”-.020”over to clean up.Did they mention anything about taper or out of round?

    Low Oil Pressure at Idle

    If the valve isn’t closing all the way it could allow the engine to hold decent pressure at low flow until the oil thins out.What did the aluminum case around the pump gears look like?

    Low Oil Pressure at Idle

    The .0035” engines are fine with 20w-50. They’ll peg a 100psi gauge at 7,000+.

    Low Oil Pressure at Idle

    I forgot all about the pressure relief. It’s very easy for the piston to stick in the bore. It may be closing, but not all the way.

    Low Oil Pressure at Idle

    We usually shoot for .0035” in the high powered stuff but went as big as .0045” in a 6bolt 4g63 block that trapped 180 mph in a 3000gt.The issue was the block and crank flexing and making contact at the main bearing. A little more room and the parts stopped wearing.The amount of high...

    Low Oil Pressure at Idle

    We ran some really big clearances in stock block casting big power builds. There is a hard drop after .0045” clearance in pressure even with all squirters and balance shafts deleted. In those engines dominator straight 60 had to be used as well.As for the op’s issue I seem kind of stumped too...

    2G Subaru 20g turbo capatability?

    Most blown turbos need more than bearings and seals, just like most blown engines need more than bearings and seals.

    Block modification for alum rods

    I don’t know if they’ll fit without cutting the main caps in half. I remove a lot of material from them for 88mm stroke builds. You’ll also have to notch the bottom of the bores.

    2G FP green hot side bolts

    I don’t thread anything into them once that happens. I redrill holes and use m8 bolts and nuts. That way when (not if) they seize, I just break them in half with a breaker bar.

    1G Block after crankwalk

    If the crank touched the block where the thrust flange is supposed to be the block is junk. There are no oversized thrust bearings.I’m sure you could have the surface machined and use some shim stock, but it’s not a 350 and this isn’t 65’.

    General Any interest in a speeduino plug in ECU?

    I’ve used det cans myself, but in the current market individual cylinder knock control is available with good aftermarket ecu’s. Now if you can come in under ecmlink on pricing you could probably sell 50-100 units.

    General Any interest in a speeduino plug in ECU?

    Any Knock control, boost by gear, or ignition retard and cut limiters? If you can get all that in for under $1,000 people would buy.

    2G Clutch recommendations (modest)

    I never run aluminum, I’ve seen too many off them egg the bolt holes out and have bolts back out.My favorite setup is a competition clutch steel flywheel and a act2900 with a 4 puck. It can’t be to bad. I bet a guy at work he couldn’t drive my car across the parking lot. He got right in an...

    2G Clutch recommendations (modest)

    While it’s not what I’d recommend in this case, I’ve put 100,000’s of miles on puck clutches in city traffic and every where else.They slip fine, you just have a very narrow window.I do recommend a puck or solid disk and heavy plate until you absolutely need a multi-disk.

    2G Is Cylinder Head too low? Valves hit pistons.

    You didn’t pump the lifters up with oil did you? The lifters need to all be left empty if they’re new, or bled back down if they aren’t new.
  43. donniekak

    1G Stuck in gear? shift fork?

    It’s fairly easy to cut them out of sheets of shim stock.With the age of these transmissions and they way they get used I’d plan on replacing bearings for wear. If you wait for one to come apart it’s a total loss of all hard parts.

    2G 2G AUTO crank balancing details

    You don’t balance the flywheel with the crank and internals no matter what. Then if you replace the clutch you need to rip the engine apart.We’ve spun 11,000 rpm’s many times on untouched stock cranks. It’s an in-line 4, not a v engine. It’s a zero balance the crank, and as long as the rods...

    2G 2G AUTO crank balancing details

    Never balance a flex plate, flywheel, or damper with the bottom end. Then if you need a new one, you have to balance the whole engine again.An in-line 4 the crank is zero balanced. You can swap out rods and pistons, as long as they’re all matched in weight.

    2G EVO Oil Squirters in a 2G

    Make sure to open up the ring gaps enough. Butting rings cracking the piston are one of the issues with a bone stock engine you can fix.As mentioned a stock bottom end can handle a t28. The opened up gaps just save you from problems if you run a little lean from either pushing stock fueling...
