I hope you will install AN fittings, it will thread right in,

Quit cooper !!!!!

I have O4 s60r head laing around , Probably will jump on It as soon as my jobs will slow down a little

Like how you do you work.

Good luck.

Don't need expensive/clunky AN - the copper pipe is great! There's no pressure to worry about anyway, with the new tank :lol:

This is what I drained from the catch can after two weeks running 22+psi- mostly water - a small amount of oil residue

Decided to take a little out of the exhaust valve guide lump...

Intakes are all done - nice wide straight shot!

Robbie - I thought you already had a setup like this?

Nope, just running the stock pcv system venting to atmosphere, but I'm currently only running a 16t on low boost breaking in the motor, I will be using a breather system similar to yours tho, just need to get going on it, just not high priority till I get my big turbo on it.

Head looks great! Any pics of the baffels behind the bungs that were added?

What is your bigger turbo? Something like mine or a Garrett BB?

I'll take a pic of the baffle - it's just a piece of aluminum plate cut/welded to fit in, with clearance for the cam lobes, of course.

Could have bought my HX40 I had a while back. But a diesel buddy of mine took it off my hands for more than I paid for it so I can't complain. I figured it was easier than searching for a smaller hotside side and a proper wastegate.

I better install one of these turbos soon instead of buying them and selling them for something else :) I think I found the one I'm going to run soon!

Great thread Hussein! I'm waiting until you get everything finished to see whether or not I'm going to get my original head majorly worked over or just search for a newer head, thanks for being the guinea pig :)

Scott paid god -knows-how-much-money to have his old head ported

to end up with a head that still looks to have smaller ports than a stock late head

on top of which, unless you pay to have the head flow benched, you can't tell if you're just fucking up the flow.

IMO, cheaper to pay $200 for a late head & have it cleaned up like I'm doing.

Very good point, but finding a head for $200 up here is going to be tough. Yards aren't as cheap as down in the states. The guy who is doing my build said the head work wouldn't be much - what his definition of not much is I'm not sure as he mostly does race engines for sponsored teams - I was hoping cheaper than sourcing a late head. But solid would be nice as I'm hoping to have a rev limiter around ~7500.

Another side question, are 2.5 R heads better than normal 2.5T heads? I know of a crashed S60R, so maybe I'll inquire about getting the head off the engine if it's still available.

If it's the dual VVT, then the intake cam is different. If I had the choice, I'd have gone for that instead for sure.

EDIT: Don't forget, you also need all the plastic engine covers, and the torque mount complete, if you are going to check into it

Are all +'04 duel VVT heads the same then? Engine covers shouldn't be a problem and same with torque mounts. The torque mounts are the same as single VVT heads are they not?

Referring to the listings in Ozzimark's Thread, the difference in the dual VVT head application is either LPT or HPT in the R & T5. Based on that, the LPT's all get one intake cam, the HPT's get another. Exhaust cams are the same across the board. Head gaskets are also different, depending on application. I went with the B5234T3/B5244T5 head gasket. In terms of all the covers/mounts, if you already have all that stuff from a 99-, then you should be good to go.

Not certain, but it appears that way. We won't know for sure until someone measures up the duration on the cams. Hussein, can you have your machinist check your cams out?

Also, not to be a dick, but it's dual. Duel is what you do with guns or knives. :lol:
