My RB30E is finally here. The first one I ordered ended up in California instead of Atlanta. Got my money back and finally got this one here.

Now I just have to get my other parts here and start building. Anyone want anything off of it? Let me know.

Good to know others are getting the RB30 disease! What head combo do you plan on using?

I am going to get a 26 head and slap it on there.

Hopefully today I can tear it all down and see what unplanned purchases there are. Everyone says stock con rods are similar in construction to "high dollar" con rods, but I have never seen a picture.

The 26 head is my choice as well. My block has been tapped out for the larger head bolts. I am using the stock rods. My power goals are not to the extremes. I just want a nice streetable setup.

Dang dude. That hurts. (this is where you come back and say "Yeah. That's what she said")

What size/thread count bolts do I need to mount this thing up on the engine stand?

RB30s are starting to get easier to source, but I still have no real idea where to get just an RB26 head. I was thinking about doing the conversion with my RB25 but it looks like more work and then Ill have a block left over I probably cant get rid of locally if anywhere.

That looks nice though, keep us posted.

$250 US for the motor. I gave the shipper $600 total to get it here, although I think shipping was only actually another $250

$600.00 was about what I paid a few years ago for my RB30. You are actually paying for shipping between multiple locations and handling fees. There is the frieght charge from the sellers location to the nearest shipping port.There is always a port entry fee, forklift fee, and warehouse fee. This is for the entry and exit port. Finally there is the frieght charge to get it to your door if you do not pick it up at the port of entry.

If you do not have the RB26 top end already, you might be better off getting a complete RB25DET and use everything except the block. I have spent a lot of time locating and buying all the parts needed for my swap.

Yeah if you include handling charges at Hartsfield Warehouse, it was $672.50. There was a $50 handling fee, a $20 forklift gas fee and $2.50 we just felt like it fee.

Then if you include the other $50 I spent renting a truck from enterprise, you are up to $722.50

Still not too bad to get motor here from out of the country.

I am probably going to get a whole 26 from J-Spec and then build a single overhead cam AWD go-kart Yeah, I'm a retard like that.

Lots of the hidden costs are in the machine shop labor. Such as:1. Tapping the block for the larger RB26 head studs2. Tapping for the relocated tensioner pully3. Hot tank and surface of the block4. JUN collar on the crank shaft5. Balancing the internals6. Boring and fitting the 20 over pistons. I have a custom set coming from Wiseco that are supposed to yield a 9.1CR. There is an $800.00 expense right there. 7. Valve job and micing out the shim clearance. (the shims are $8.00 each)8. Blocking off the rear oil feeder to the head and installing a restrictor in the forward feeder (RB26 head is solid lifter and does not need the extra oil. It is blocked on the RB26 block)9. And we still have not assembled it yet!

Even with a complete RB26 clip, you are still going to need a RWD RB25 transmission. More additional costs.But I do like your idea of the SOHC AWD Go Cart!

RB30DETT sounds better than 2jzgte. Not as much of a tongue twister

I finally had a chance to tear down the exhaust side of the block today and frankly I am a little scared. Is this bad? Should the exhaust manifold be stamped with the mark of the beast?
