Ultra Racing. I Saw Them In SuperStreet OR Some Other Mag. I Got Mine Off OF ebay.

I'm not too convinced porting it is the right thing to do. Sure you have the potential to make more power, but remember that this is a HIGH compression turbo engine, so I think it's going to be fun enough on stock ports. We'll have to soak it down with enough fuel to prevent detonation as it is, and I believe porting would only contribute to the engine's detriment. For the amount of power this engine's going to make, I don't think porting is really all that necessary. He also bought a blown stage 3 BNR that I'm building for it as well. It's definitely going to be more engine than his tires can handle.

So far, it's coming along nicely. I hit a snag with the exhaust sleeves, but that's not going to be that big of a deal. Just another couple hours on the grinder and he'll have matching NA/T sleeves. From that point, I have to finish cleaning the irons and clean up the exhaust ports some, then the engine will be assembled and ready to go.

Are you still planning on using the Pineapple exhaust template?

I am sure I am going to spool right off of idle.

I got the turbo back from Evergreen turbo out of Ocala FL, Holly crap Charlie does get work. I swear he sent me back new parts instead. The bearing housing looks awesome so does the compressor and turbine. The parts do have a slight layer of oil on them I guess to prevent rust.

You shouldnt have to modify another NA sleeve.
there is a spacer pressed in NA housings you have to pop out, then you can use the TII sleeves in NA housings

Of course! It's your engine, so ultimately you make the decisions.

Most likely. Which is great for what you're wanting out of this car. Honestly, how long do you expect to spend at full throttle when autocrossing? What you need is something with good throttle response, and can generate a fair amount of torque in the low rpm range. So high compression rotors give it the crisp throttle response and quick turbo spool, and the stock intake ports will keep the low end torque. Hopefully, it wasn't compromised much by the porting of the exhaust ports. I didn't touch the top part of the port though. That way there won't be any overlap between the intake and exhaust, which is great (up to a certain point) for high rpm power, but sucks down low where it really counts.

By the way, NICE looking turbo! Dude, I TOLD you Charlie does great work! I can't believe that's the old TA34 wheel. I assume he had to machine it down some, so hopefully you got some undersized journal bearings included in the package?

That's some good info my man. I'll look in to that. This is my first experience popping out those little bastards, and let me just say that they're not easy. I did end up breaking out the welder and putting a little bead on the end of the roll pin and slide hammering it out using my custom vice grip attachment. The screws just didn't work. The welder didn't damage the housing at all (surprisingly).

I think charlie said he did put oversized bearing in there. he also said the shaft was a little bent and he fix it. I have to say the best $110 i spend.


hmmm, I am sure I could maybe paint the bearing housing with hi temp paint. but do I want to.

No, you don't want to. There's oil on there right now, and eventually what will happen is the cast iron will get seasoned like a cast iron skillet, and there will be a protective layer over it. If you paint it, the only thing that will happen is the paint will burn off or chip, exposing clean cast iron to rust.

And I wanted to get a visual of what I was doing before I started whacking on the exhaust ports. Not to say that I didn't believe you TougeMonster, but I follow a little guidance called "Trust, but verify".

Ya sorry I didnt load pics
.I have some on my build thread but I uploaded them from my phone
couldnt figure out how to link them from my thread to this one

I had a day off :lol:

I'm missing some pieces still, as Raksj04 still has most of the engine peripherals at his house (about 45 min away), and we're still missing some gaskets. Otherwise, she sounds really nice when spinning with a breaker bar. POOOsh, POOOsh, POOOsh, POOOsh, POOOsh, POOOsh.... I think those Goopy housings and seals are going to do REAL nice things for the compression numbers :icon_tup:

By the way, that's a T04E hybrid. It was a BNR stage 3 hybrid that caught an apex seal to the turbine, so it chewed up the P-trim wheel that was on there. I had a TA-34 wheel lying around so I had Rick send it out with the T04E compressor wheel to get balanced. So the TA-34 turbine is sitting inside a stock S4 turbine housing, since the S5 housing that came with the turbo is bored out for a P-trim wheel.

And thankfully I had a bunch of extra parts hanging around the house. There wasn't a turbine seal or dynamic seal ring in the box o' parts from Evergreen. Regardless, he does excellent work! It spins so smooooooth. :)

What bolts are you holding the turbo manifold with?

Nice work. I saw it, she is pretty.

I did manage a little work today. I had to modify the wastegate actuator to reach the S4 wastegate. I guess the S5 and S4 ones are very different, so I had to bend it a little more straight and extend the rod about 20mm. Not much work, but it took a little bit of fabrication.

I'm trying to figure out now if I'm screwed or not. 1st off, how large do I have to make the coolant passage for the turbo supply on the new NA housing? And from searching, it seems that there's a little groove machined in to the housing for that O-ring. Do I need to copy that groove as well?

Hmmm.... I'm considering using the nipple at the rear iron for the coolant source for the turbo now.

I used the rear iron. Check my thread for pictures.

This?

I think I like this idea better. Only because I'm not too sure about having to dremel the little ledge for the o-ring on the rotor housing. I could just see that leaking pretty bad if I were to somehow screw that up (which seems pretty easy to do).

Thoughts?

Great rebuild so far man. Looking at getting some fender bars for my car too. Hope they're worth it. Subbed to see where you go with it in the future :D

Still using the twin scroll? I saw it flapping in the breeze a few pics up.

there is a update coming soon. still using the twin scroll the car should be ready to fire up soon. I will upload some pics this week. and maybe a video if she fires up.

Pictures!!!

Here is the S5 bumper I picked up from a junkyard, for $20 I can't pass it up.

Here is a video of my try of starting the car. I had to blip the throttle to keep her running. I have vacuum leaks and oil leaks. The pic below will take you to photobucket to view the video.

Is the battery good? I think you may need a bigger ground or power wire for your battery relocation. I had slow cranking when my ground wire from the battery was too small. I doubled it up and it cranks at a solid 250 RPM now :)

I got her to Idle but I still have a few oil leaks.
