FrAnkRYzzO Perry Hall Maryland, US $upervillain for Hire	If any of you have read my thread on choosing a power adder, I've decided to boost my TC. I'm looking to get some information on what I need to acquire and what I should potentiall upgrade. Things I have or are on the way: Turbos w/ wastegates FMIC 22.5/8/3.5 core main and rod bearing set (got a good deal) emanage ultimate with pnp harness and upgraded a/f harness Things I'm looking for: 2AZ_FE head for PNP Custom Exhaust manifold Intercooler/Intake piping Flywheel/Clutch What else do I need? I was advised that putting a BOV on a sequential TT setup may not be a good idea because it could potentially throw off the syncronization of the two turbos. I'm only looking to get 250-275whp out of the setup to keep it reliable as a DD, so I was figuring on keeping the rest of the stock internals. I have been told by many people that the tc's bearings are a weak link so I figured I'd upgrade those due to the deal I found. Fuel Management? Will the stock fuel pump be reliable at these levels of boost and hp? I don't see this going much more then the equivalent of a stage 1 kit, so I was figuring I wouldn't need a new pump. Than again an adjustable fuel regulator couldn't hurt... I'm sure I'm forgetting/missing something. Thanx for the help ............... Search or one of these adorable kittens WILL DIE!

Mugetsu Hollywood Florida, US Scion Guru	well i'm the furthest thing from a turbo expert BUT your doing a sequential TT set up? for the hp you want, a single turbo would get you there and its a simpler set up.(if you want to do it just to do it then thats cool..i guess) you'll need injectors too. i think the fuel pressure regulator on this car is in the tank, so while your back there you may as well slap a walbro in there too(and a return system lol) your best bet is to examine and study one the kits offered by guys like Dezod/Treadstone and build one off of that. wow that was more intense than that one time I forgot how to sit down...

FrAnkRYzzO Perry Hall Maryland, US $upervillain for Hire	I'm attempting the tt setup because it hasn't been done yet. I thought it would be a cool project. There's tons of turbo tc's out there, but have you ever seen a TTtC? Especially one made with all toyota parts? The supra turbos are very reliable, and if I ever wanted to get more hp out of the car, they're capable of a lot more then what I'm trying to get out of them now. What size injectors would you recommend? 440? ............... Search or one of these adorable kittens WILL DIE!

SoFloTC Boca Raton Florida, US Godlike Advisor	um more on the lines of 550cc.. and ya the numbers u posted a single turbo would get u there without to much work.

FrAnkRYzzO Perry Hall Maryland, US $upervillain for Hire	I know that I could do this with a single turbo, but my goal is to make something unique. I'm just trying to get some advice on how to make this idea work. I appreciate the help ............... Search or one of these adorable kittens WILL DIE!

Mugetsu Hollywood Florida, US Scion Guru	"Fullrace" makes a manifold for a TT set up, not sure if its for the TC thought... 440cc are good for 300hp but 550cc have room for a boost controller EMS you got the new AEM F/IC or you could go with SplitSecond if you plan on "dipping yo finga" into tuning your self. you will prob need slim fans for this set up. could you post a pic of these turbos? wow that was more intense than that one time I forgot how to sit down...

FrAnkRYzzO Perry Hall Maryland, US $upervillain for Hire	Here's picks of the turbos as requested: As you can see, although the supra has a inline 6, the exhaust manifold is split 3 and 3. Because the exhaust manifold on the tc is all 4 ports together, this creates a problem in splitting it off to the turbos. What has been suggested to me is to move the turbos out closer to the fender wells to allow room for the exhaust manifold to get where it needs to go, and to allow a fabricator more room to work with. ...............

Mayo Rockville Maryland, US *The Guru*	Haha, or you could 3 cylinders go to the turbo and 1 cylinder just vent. Haha, kidding. Alright, so Im a little (very) confused. Is that a sequencial set up? Because it looks like 3 cylnders go 1 turbo each.

FrAnkRYzzO Perry Hall Maryland, US $upervillain for Hire	Here's the wiki answer Quote: The MKIV Supra's twin turbos operated in sequential mode instead of the more common parallel mode. The sequential setup featured a pair of small, equally sized turbos, with ceramic blades for the domestic Japanese market and steel blades for export (USA, Europe) markets. At first, all of the exhaust is routed to the first turbine for reduced lag. This resulted in boost and enhanced torque as early as 1800 rpm. Approaching 4000 rpm, the exhaust is routed to the second turbine for a "pre-boost" mode, although none of the compressor output is used by the engine at this point. Approaching 4500 rpm, the second turbo's output is used to augment the first turbo's output. This setup differs from other twin turbo designs which run both turbos in parallel. The sequential mode provides greater low RPM response and increased high RPM boost. ............... Search or one of these adorable kittens WILL DIE!

What I don't get is that you're attempting to do something that's "never been done before" yet you want it reliable for a DD? Come on now brothah.. Just stick with a single turbo setup if your goal is only 250-ish whp. Cheaper and somewhat more reliable than an experimental TT setup The Thread Killah

java09 Honolulu Hawaii, US Godlike Advisor	whyindustries.com=turbotoyotas.com, both Todds companies.. his EL mani cost 850.. single turbo your easily looking at double plus change for him to fab you up a TT mani or set up. then he puts his time/effort into the cost and shipping.. your looking at a very "ouch" number. haha you would have a lifetime warranty though on all fabricated parts made through his companies! thats a plus! id say your best bet is to get a local shop you "trust" to fab something up for ya! good luck though mang, hope it works out for you! 2008 Turbo Scion tCizzle POWERED BY TURBOTOYOTAS! 310WHP, 272WTQ more to come_..

FrAnkRYzzO Perry Hall Maryland, US $upervillain for Hire	Yeah, one of the guys helping me with the project found a couple local guys that do custom fab work, and I'm waiting on a quote from the good one that uses flow bench testing. I new this was going to be the biggest expense of the whole setup, but for the price that I got everything else for, I'll probably still come out cheaper then buying a full kit ...............

MrScion07 Rochester Massachusetts, US Godlike Advisor	Might b a one of a kind thing and i know thats wut ur looking for. But if you want to b one of a kind just make a custom turbo setup. You found people that can make u a turbo mani have them make u a custom one of a kind. Idk just seems like ur going to go threw more of a hassle to get this to work then its really worth. It would b hella cool if u did it tho.

MrScion07 Rochester Massachusetts, US Godlike Advisor	Also i wouldnt bother with fuel pump where ur only aiming for 250-275 like u said thats pretty much a stage one kit. But injectors would b nice 440 would work 550 u could do too. Intercooler piping just get from dezod or something you also need nessasary guages and oil lines for turbos. BOV and flange remember ur vac lines lol ummmm probaly gunna need a custom down pipe right? im no pro but labor and all it might get expensive especialy the down time u would have with fabing a mani for those twins cars gunna b in the shop for awhile. Where a kit from dezod you and your buddys could install in a weekend im sure and another weekend you could get it tuned. idk sound like a big process

Rabid_Lemming Cumming Georgia, US Scion Guru	There is a guy on this site who has an ebay sale going right now for his totalled tC. One of the items is a 2AZ-FE motor for $750 or best offer. You can build that one, or use it for the parts you wanted to send out My car isn't the fastest car out there, but I'll tell ya.... Sometimes I haul more ass than a pimp driving a caddy full of hoes.

Heres an idea. do a batt relocation to the rear, this will clear up the whole of the driverside side of the bay,some thing like this...(scroll down) http://www.scionlife.com/...er=asc&&start=380 also running the TB charge pipe through the fender CAI style is a good idea. this will give you plenty of room to push the turbos forward. the fab of the manifold and the down pipe is deff going to be your biggest challenge. wow that was more intense than that one time I forgot how to sit down...

operatic Houston Texas, US Scion Guru	You know what you could do in regards to the turbo set up is have all the exhaust runners go to the first turbo. Then the exhaust side of the first turbo goes into the second turbo. Not sure if that would be effective though...

However, with what he has, he cannot really do it because the turbos are the same size. Usually when you have a setup like that, a smaller turbo spools first into the larger one to decrease turbo lag. Attempting this will be difficult to say the least because there is a lot of precision tuning involved. My car isn't the fastest car out there, but I'll tell ya....

FrAnkRYzzO Perry Hall Maryland, US $upervillain for Hire	I'm thinking that I'll have to relocate the battery to the rear. My friend and I were discussing this the other night. I think it will be more economical to have the xhaust manifold made with longer equal length tubes and space the turbos a little wider apart. This will alleviate the challenge in trying to make some goofy looking exhaust manifold that would have to be cast out of a single piece of metal. The next challenge is going to involve the timing of the sequential setup. I need to do a little more research on how the supra turbos are activated, but it would seem at first glance that it would be vaccuum pressure. The wiki quote I posted states that the second turbo starts spooling at 4k and is active at 4.5k. I'm assuming that a six cylnder will have more vaccuum pressure at 4k then a 4 cylinder. If that is true, then I might have the pressure required to activate the turbo at 5k or 5.5 k which would render the usefulness of the 2nd turbo to be very limited. I may be way off with this assumption, and further research will be required... I saw that ebay auction, and I think I can get a whole engine shipped for about 10 dollars more then the selling price of that one if I buy the head and short block separately. I'm talking to a couple of individual sellers and waiting for a response and some more money. I think I'm going to have to rob a bank this weekend ...............
