7635, Rebuild Time... opinions please
Posted by Hult250R, Jan-02-06 11:02 AM
Its time. Bottom end is getting worn out. Im tired of trying to tune a worn out motor with tons of Phantom Knock, It seems impossible to get a good tune with this thing. Its got quite a bit of blow-by, its smoking and my leak down test proved it too.

So... Ive been poking around looking at prices and such and Im wondering what parts I should go with.
Heres a List I got from SlowBoy. Because they have everything listed with prices Im using them just as a reference, Not necessarialy going to buy from them.

Pistons:
Ross $440
Wiseco $440
JE $550

Rods:
Eagle $350
Scat $320 (with ARP studs installed)

Im going to get all APR studs, Not sure what bearings to get, Clevite? Stock?

I guess my biggest question is the Pistons and Rods.
Is there a huge difference between the Eagle and Scat?
What about Pistons? Any opinions on the ones I have listed? Im a big fan of JE's in my Quad but not sure about how they hold up in a DSM. Or if theyre worth the extra $100

Im running a T04E 60 trim turbo just FYI

Opinions guys... :)

Why not get that stroker kit from that shop across the river? I seriously thought that I ripped them off, but the kicker is that the crankshaft is forged.

I thought about it but I dont want to spend that much.
What do you mean you thought you ripped them off?

I haven't heard much about the Scat rods, so I'd stay away from the them. Eagle rods are a good choice for you. I run a TD06 20G and went with Wiseco pistons but kept the stock big rods, all ARP hardware. I didn't want JE pistons simply because of the piston slap associated with them. The piston-to-wall clearance needs to be greater for the JEs versus other forged pistons because they expand more than the others after warmed up, so at initial start-up until they warm up they "slap" the cylinder walls. Ross are excellent pistons and a lot of DSMers use them. They must have come down in price, I remember them being closer to $600.

Cody is right. Stay away from JE pistons in the 4G63. They cause premature wear due to excessive slap on warmup. I also have not heard much about Scat rods. Stick with Eagle for sure there.

Ross or Wiseco are your best bet for pistons, and get the Clevite bearings as well.

I say that I feel I ripped them off, because if you look at pricing for everything you come out definately with what you paid for. If you choose not to stroke it, I'd go with this setup:

Clevite 77 main and rod bearings
Eagle rods (all Eagles come with ARP)
Ross or Wiseco pistons
All ARP studs

Personally, I'd stroke it. Faster spool-up and more power with less boost. The kit comes with everything plus the crank except for the ARP head and main studs.

Now to start the list of everything else Ill need to buy, Gaskets, Bearings, ARP's... Yay...

Are you doing it yourself? Minus the machine work, of course. I rebuilt my 4G last year and really enjoyed getting into it, more than just bolt-ons.

Ok guys, heres the update...
Parts are starting to pile up:




Ross Pistons, Eagle Rods, SS Valves
Not shown are bronze guides, seals, and J.A.M. Valve springs.

I still havent got bearings and a few other misc. things also.
Also on the list is a new OEM front cover/oil pump. Im not going to trust a brand new motor to a used pump.

Have fun paying $300+ for that pump. Just getting new gears for the pump since it's mechanically driven? This is what I did, since the housing looked perfectly fine. Brings the cost down. Get those bearings and send that block off to get machined.

I did some research on Scat. Seems like they're huge for Honda's. I'd definately stay with Eagle, tried and proven. Good choice on the Ross switch. I believe that they R & D everything that happens in the combustion chamber. Good luck with the project. Keep posting up progress.
