JustinOlson Posted December 5, 2007 Share Posted December 5, 2007 Well, I might be over doing it a bit, but what the hell. So as I've stated in a couple threads, I'm doing a 2JZGE swap into my car with a TH400. I've been going back and forth on which turbo I wanted to choose for my 2JZ build. I decided that I wanted to run a divided manifold with dual wastegates to gain spool. All was good when I was drawing up the collector for a divided T4 collector. The 1.5" schedule 10 piping doesn't fit up too well to the T4 flange. Anyway, to make a long store short, I decided that a T6 divided manifold would be the only way to go. Theres not much for information out there on these Borg Warner turbos with the divided t6 turbine housings. I ended up choosing a S480 which is right in line with a garrett GT4780. The S480 has a 10" overall diameter with a 5.5" slip fit inlet and 3.0" outlet. The turbine housing has a 5" outlet, so I'm just going to do a 5" dump right behind the passenger side front tire So I need to fit the S480 along with two Synapse 50mm wastegates in this little Z with the stock hood. Wish me luck. I have yet to yank out the L28, but that should be happening over this christmas break. and two of these guys: Here is a comparison of the Divided T4 collector vs the Divided T6 collector. You simply can't make the 1.5" sch 10 pipe fit the t4 flange better without porting and hammering.. Regards, Justin Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted December 5, 2007 Author Share Posted December 5, 2007 Based on the pictures and talking to Z-gad, I think I should have room for the turbo. I'm not sure how the wastegates are going to be layed out. I'll just have to figure it out once the engines mounted and I start mocking up the turbo... Z-gads car with a PT76: The turbo on the left has the same compressor cover as mine. The turbo on the right has a compressor cover the size of Z-Gads. This picture gives me hope Here is a picture of the TPS supra with the S480 and the medium sized compressor cover (shown in the center in the above photo). The TPS supra has gone as fast as 8.70's with the S480. They tell me they think it has 8.50's in it on a well prepped track Justin Quote Link to comment Share on other sites More sharing options...
majik16106 Posted December 10, 2007 Share Posted December 10, 2007 thats gonna be a fast drag car... just cut where you need room, if all your gonna do is drag race.. you could always tube out the front, save some weight and have all the rooms you want.. lol.

JustinOlson Posted December 12, 2007 Author Share Posted December 12, 2007 I'm going to try and get it all to fit in the factory engine bay. I'm hoping it can make it all fit. I'm having the collector and turbine flange machined this week. I am placing the muffler right behind the passenger side front tire. Should sounds pretty sick with a 5" dump Justin Quote Link to comment Share on other sites More sharing options...
zbratt23 Posted December 12, 2007 Share Posted December 12, 2007 Justin, you are crazy. I think I'm gonna sell my 2jz and get a 1jz instead, it'll better suit my wants. But when I get back from Iraq, i'm movin to portland, I gotta see this thing in person Quote Link to comment Share on other sites More sharing options...
hughdogz Posted December 12, 2007 Share Posted December 12, 2007 Justin, you are crazy....I gotta see this thing in person x 2 !! I can't wait to see you run at the re-paved Portland International Raceway next year (Woodburn dragstrip too!) Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted December 13, 2007 Author Share Posted December 13, 2007 I hope I can get this thing running by this next summer. I'm spending money like crazy trying to get everything lined up. I'm doing the cage right after christmas!!! I'm trying to get the motor all lined up with the TH400 before I tear the good engine out of the car.

JustinOlson Posted December 13, 2007 Author Share Posted December 13, 2007 Here are some renderings using the 1.5" sch 10 on my divided T6 S480 & twin synapse 50mm gate setup =) Regards, Justin Quote Link to comment Share on other sites More sharing options...

JustinOlson Posted December 13, 2007 Author Share Posted December 13, 2007 I'm really going to bed now... Regards, Justin Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted December 13, 2007 Author Share Posted December 13, 2007 I'm going to have to model the S30 engine bay and 2JZ engine placement so that I can accurately model this header before i build it. I'd rather go through a half dozen revisions on the computer before cutting metal. Justin Quote Link to comment Share on other sites More sharing options...
