StreetFighter Posted March 29, 2010 Share Posted March 29, 2010 I'm the fabricator for Boost Logic, and this is our GT45-80 DBB and GT35R DBB compound turbo,twin 60mm and single 44mm wastegates. It's a stock engine, so I have to leave it at around 800whp, but on high octane fuel it should be capable of 1000+whp. The car weighs around 2600lbs. Still have another 2 days of mechanical work and fab, and another 2-3 weeks for paint and body. Quote Link to comment Share on other sites More sharing options...
Daeron Posted March 29, 2010 Share Posted March 29, 2010 Wowee wow!! That thing just screams "wheelstander" to me (even if that makes no sense; big Vroom has always made me picture a car flipping itself under its own power) Quote Link to comment Share on other sites More sharing options...

frank280zx Posted March 29, 2010 Share Posted March 29, 2010 LOVE it .. just 1 question stock engine meaning bone stock ? cast pistons etc ? And why is the bigger turbo feeding the smaller Turbo? would you not rather want it vise versa ? Quote Link to comment Share on other sites More sharing options...
williamb82 Posted March 30, 2010 Share Posted March 30, 2010 actually the stock 2jzgte pistons are forged. as for the larger turbo feeding the smaller one, this is the way it should be. look under the hood of a semi with a compound turbo kit. the smaller one is able to suck air through the larger one and then the larger one blow through the smaller one once it comes up to boost. if it were in the reverse the smaller turbo would be an inlet restriction to the larger one.

StreetFighter Posted April 1, 2010 Author Share Posted April 1, 2010 I am on stock CAST 2JZ-GE pistons and rods. 2JZs (all of them) come from the factory with cast pistons. I have a lot more work ahead of me, but the car should be done in a week or less, and paint and body work will be done shortly after. Thanks for all the compliments.

JustinOlson Posted April 1, 2010 Share Posted April 1, 2010 (edited) Are you running both 60mm wastegates to bypass exhaust gas around the smaller turbo? Edited April 3, 2010 by JustinOlson Quote Link to comment Share on other sites More sharing options...
StreetFighter Posted April 2, 2010 Author Share Posted April 2, 2010 Are you running both 60mm turbos to bypass exhaust gas around the smaller turbo? Yes, both 60mm wastegates are used to bypass the small turbo. twin 60mm gates on the small turbo, and only one 44mm to control the large one.

Z-Gad Posted April 2, 2010 Share Posted April 2, 2010 I am on stock CAST 2JZ-GE pistons and rods. 2JZs (all of them) come from the factory with cast pistons. Thank you for posting this...I was going to mention something, but couldn't bring myself to type it up LOL ... there is so much mis-information out there. I anxiously await your results Quote Link to comment Share on other sites More sharing options...
Sparks280zt Posted April 2, 2010 Share Posted April 2, 2010 Nice build, although I know the turbos are correct, Hey I see the crappy CAT twins all the time, it always confuses me still! Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted April 2, 2010 Share Posted April 2, 2010 Yes, both 60mm wastegates are used to bypass the small turbo. twin 60mm gates on the small turbo, and only one 44mm to control the large one. Have you seen a benefit to use two 60mm wastegates on this new setup vs a single 60mm gate on the previous build? Quote Link to comment Share on other sites More sharing options...
StreetFighter Posted April 4, 2010 Author Share Posted April 4, 2010 I have not done any tuning as of yet. I do not know if two will be better than one, but I was hopingfor about a 50% decrease in minimum boost fromthe small turbo. Previously minimum boost from the small one was 7psi, I'm hoping for 4-5psi, and slightly better controll of the whole system. Also these wastegates have been modified for further valve lift, allowing it to run more as a bypass and less like a wastegate that merely cracks open.

williamb82 Posted April 30, 2012 Share Posted April 30, 2012 I am on stock CAST 2JZ-GE pistons and rods. 2JZs (all of them) come from the factory with cast pistons. I have a lot more work ahead of me, but the car should be done in a week or less, and paint and body work will be done shortly after. Thanks for all the compliments. actually, upon further research, the n/a, and turbo 2jz pistons are all hypereutectic, not forged. better than normal cast pistons. either way, this thread needs more pics!
