Guest ON3GO Posted July 20, 2005 Share Posted July 20, 2005 Hey guys. im building my exhaust manifold for my VW rabbit. this car is just to see what i can build, using whatever parts i have or whatever i can build, and a few off teh shelf parts. I have 2 K03 stock 1.8T VW Golf GTI 2000 and up turbos. i wanted to use these as there free, there small, and should make good power for this low cost project. The engine is a 2.0 16v 4 bannger from a Jetta GLI, its sorta high compression so ill be running 2 headgaskets. YES i know, 2 sounds stupid and wont work... well i guess in the VW land this is what they do and some have 400+hp out of there double headgasketed motors. If it blows 3 months later on my engine im fine with that, i just wanna see what she can do for those 3 months lol. SO the manifold im making is tubular, S.S. , and its 2 cyls per turbo. now will this NOT work at all, or will work but be sorta a pain to tune and etc. im willing to learn so if it will work, and prob work fine but just be a pain to build and tune then im fine.. im up for the task. if this wont work please tell me why, i cant see why not as there so small. ill be pushing 18psi out of each one and will be tuning with a Haltech E6K. oh.. 2 runners that will go to one flange and one turbo will sit up alittle higher to clear from hitting the other turbo, and both will be slanted up abit so exhaust and intercooler piping will be made easier. thanks mike Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted July 20, 2005 Share Posted July 20, 2005 what's wrong with a single turbo?! easier to fix.. cheaper to maintain.. and you can run 1 big one for high RPM boost.. or a medium sized one for well.. mid RPM boost?! Seems kinda pointless except for the WoW factor Quote Link to comment Share on other sites More sharing options...
Guest ON3GO Posted July 20, 2005 Share Posted July 20, 2005 like i said i dont want to spend money on this car, i have the turbos.. they were free, there in perfect shape. a bigger single turbo would be stupid because i need one on my blue Z 1st . like i said its a big budget car. mike Quote Link to comment Share on other sites More sharing options...
yo2001 Posted July 20, 2005 Share Posted July 20, 2005 I think on 4 cyc. twin turbo would have to have #1 and #4/#2 and#3 tight together to have correct pulse to spool a turbo. Quote Link to comment Share on other sites More sharing options...
Guest PROJECTRB240SX Posted July 20, 2005 Share Posted July 20, 2005 Spool Would Be Slow And I Would Run Same Pulse Manifolds Like Mentioned Above To Keep The Turbos Flowing Equally Rather Than Chopping Up The Exhaust Pulses. It Could Be Cool If Done Right And Probably Lead To Quite Abit Of Power At Lower Boost Levels Than A Large Single. Quote Link to comment Share on other sites More sharing options...
Guest ON3GO Posted July 20, 2005 Share Posted July 20, 2005 ya i thought about the same pulse manifold design. would go on firing order right? or what? mike Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted July 20, 2005 Share Posted July 20, 2005 I would think if the firing order is 1-3-4-2, you would join 1 and 4 to one turbo and 2 and 3 to the other. Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted July 20, 2005 Share Posted July 20, 2005 Yeh 1-4 and 2-3 ... as for the turbo's... would you have 2 seperate downpipes and exhuast pipes which met up somewhere along the exhuast line or run dual exhuast?! also are you going to run these turbo's in sequence?! or simply a non sequential turbo setup?!

Guest ON3GO Posted July 21, 2005 Share Posted July 21, 2005 run them together.. the piping will be y'ed together on both the fmic and downpipe.. exhaust will dump on the front fender. mike Quote Link to comment Share on other sites More sharing options...
