I love that fat ass wastegate runner. What size gate is that?

The BL mani looks designed for a twin scroll. The collector on that double D (right back to bewbs) looks niiice. You going to run it uncoated?

Why not a billet upgrade on the twins while they are off?

So why aren't you using the Boost Logic manifold? It almost looks like it would flow better.

Looks are definitely deceiving. Look at the #3 and 4 runners and how they merge into the collector - essentially perpendicular to the flow. The DD manifold is a FAR superior design in every facet. The Boost Logic manifold is a copy of the original GReddy T78 manifold, with the flange clocked slightly more for better clearance for larger-frame turbos. It's not nearly enough, though; fitment for anything larger than a mid-frame, T04 cover requires a spacer to clear the #1 runner, and then you've got clearance issues on the strut tower. It also uses an the old 4-bolt wastegate flange and the wastegate placement makes recirculating the dump difficult, so mods would have been required to do what I wanted to do. That, and it's a divided/twin-scroll and I wanted an open collectors because 1) it sounds much nicer, IMO and 2) a may decide to try a Quick Spool Valve someday, and you need an open collector for that.

The Boost logic is a fine and manifold, and has made lots of power (over 1000WHP) but has it's quirks and I wanted something entirely different and new school anyway.

The BL mani looks designed for a twin scroll. The collector on that double D (right back to bewbs) looks niiice. You going to run it uncoated?

The collector is definitely sexxay! The whole things is work of art, and the fitment is perfect all the way up to a GT45 frame. I'm going to have it coated once everything is finalized (wastegate recirc, etc..)

I love that fat ass wastegate runner. What size gate is that?

It's a precision 66mm wastegate. Since I'm going to recirculate the wastegate I didn't want to deal with a dual gate setup. The new PTE billet turbines have been known to have severe boost creep issues since they're so efficient, so I wanted to make sure I could effectively control boost all the way down to the single digits if need be. The 66 is what Darin recommended, so this was a custom one-off for me since they didn't have a jig.


That's a big bitch!

Why not a billet upgrade on the twins while they are off?

Never even crossed my mind. That money would be MUCH better spent on a built auto/stall, and if I still planned to do that I would have just left the BL setup on the green car. There are a few 10 second auto stock twin cars! The stock twins in sequential mode are perfect for the stock auto - makes for a very punchy setup that will run 11's at 118-120MPH. In sequential the #1 turbo turned up it will make 17-18psi by 2400RPM - that's V8-like stump-pulling TQ!

Deep breath....









And here... we... go....









Easy stuff...









Shimmed the EBV to pre-tension it for increased boost on #1 with less drop off on the transition (thanks Stu for the idea!). I'll also be adding an MBC to #1 so I can turn up the boost independently:










Getting there....









2 steps forward, 1 step back... Turned out this won't work - had to remove the hotside piping on the front turbo to fit the inlet piping - just a minor setback (among many minor setbacks)










And.... I'm spent... Almost made it in one day. The hardline loom is just mocked up, so it looks a little more complete than it really is. Not much left to do at this point:









My plan is to finish up today - should definitely be doable. The worst is well over with; just have to finish reconnecting the lines to the loom (will be a pain the ass), install downpipe, intake pipe, MAF, IC pipe, etc... Then fill up with coolant, flush and burp the cooling system and drive!

a bit off topic, but would you be interested in a big brake kit for cheap?!?

your hard top supra is one sexy bitch.

Got the green Supra finished up Sunday evening, wayyyy later than I originally anticipated. I ended up having to backtrack all the way to removing the EGCV again to re-seat one of the the brass (or whatever it is) donut gaskets. When (I thought) I was finishing up underneath I noticed the EGCV wasn't seated all the way, and that gasket was partially wedged between it and lower exhaust housing.... After trying to loosen the EGCV to get the gasket to seat to no avail, I had to tear everything back apart to get to it... All was not last as it gave me a chance to re-run the vacuum lines from the EBV and pressure tank that connect to the upper loom for easier access. Overall it put me a good 3 frustrating hours behind schedule, but I'm glad I caught it when I did. I got everything back together, and completely flushed the coolant system, which took a lot longer than I originally thought (doesn't everyting!?) and then went for a drive. Man... Full BPU+ sequential twins with #1 turned up to 15psi is an absolutely blast -- super responsive and perfectly matched with the stock auto/stall. 15psi by 2400RPM and I can build 10-12psi off the footbrake almost instantly and absolutely roast the BFG drag radials -- should leave nicely at the track! It's sooooo much more fun to drive now, and it still pulls nicely up top. In fact, the SAFC is reading 82% airflow peak at 17-18psi, which is what it read at 14-15psi on the 67mm, so the healthy twins are doin' work! I forgot how smooth and quiet sequential is if you don't bring #2 online -- the TRD catback is quiet and mellow, with just a little bit of growl up top. The weather is supposed to stay nice through tomorrow, so I'm going to drive her to work.



Last round of pics for Green:


All finished up and ready to be lowered off the jack stands:










Nothing left to do but put the hood back on:










Ready to go!

Garage disaster...!









Somewhat better...

Garage disaster...!

No.....No not at all, you must see mine before you start talking disaster.
