Twin Turbo Build Thread
 

I know, I know, Mad weak sauce torque curve right? rofl, yeah unless you use ej20 IHI ball bearing turbos!!! I'm about to start the fab, so far I'm tossing my pics of what I currently have. I'll put the drawings up etc and keep posting the progress!

I'm also going to run twin Greddy Type S BOVs!!! Slash off some of the metal on my xtra fly wheel, and my god do I need a horn button for my momo course : (

lol, I also picked up a nardi knob and eb handle!!! Had to sand and refinish the handle but I'm friggin excited over the details. And hell I'm even happy about the old scuff plates I dug up!

The best part is I got most of this stuff at a yard sale? A guy wrecked his M, and had shelves of parts, it was like a dream.

If you guys have any suggestions feel free to throw down ^_^

I see you're a fan of the macro mode.

Welcome. Curious to see how your project pans out.

Do some searching, the twin turbo thing has been done. Do yourself a favor, throw those ksports in the trash.

Yeah I've seen some cats primarily role with the stock rx7 turbos... But there torque was a little late in the game. I'll post the turbo map for the IHI set up tomorrow, and if I run a semi sequential by only cutting say 30% flow through the secondary I may be able to help the low end even more. "I'm going to have to research the hell out of that though because I can't let that turbo backspool!" If any body has an Idea about that too it would be soweet!

lol, yeah I was sporting my 50mm 1.4 really saps the dof, got every prime Nikkor - the 200mm fixed 2.8 "chances are I'll nab it soon!"

I've seen you around town once or twice. Should be interesting to see how your project goes.

Is that a 99-00 head I see? The manifold looks like it, but i could be wrong. If it is you can always use my engine as a reference, although my job wasn't the best 99-00 headswap haha.

have you seen TurboTim's setup?

Yes, looks sweet, I'd like to see pics of it, but I couldn't find any when I dug around. If you know where I can chek it out please ping me! I'm hoping to do a little better on my torque curve though ^_^

Don't tell me you're going go to through all that effort and use that retarded bandaid.

there are pictures, video's, and threads. the search function as well as google is your friend.
and if you plan on doing a twin turbo setup and use bandaids instead of a good ems go end yourself now.


One other thing I wanted to mention: I'm always the guy all for "unique" builds and trying to do things differently. Trying new ways to make more power/be faster etc etc etc. But when there are plenty of turbo's out there that will be able to spool instantly as well as put down good power, as well as ones that would be a little laggy but make humongous power why waste all this effort on something that wont do either one thing perfectly? Even with small ball bearing units you still wont have the response of a v8. With the units being as small as they are you still wont make big power. Why not just do a v8 swap: instant throttle response AND big power? Seems like it would be the best solution for someone like yourself.

interesting.

Albumleaf, Don't be that guy...

Oh, yeah
 

Railz you kick ass for building your shit, I'm going to run supra injectors too! Oh, and I forgot to mention, My boss motor runs on points. "I like bandaids you guys are just pissed cause mine are ninja friggin turtle"

Who let Hyper back on the site?

No but seriously, a bunch of shitty piggybacks?


I'm also curious, why do we want to see a macro image of: a flywheel surface, a harddog label, a shock adjustment knob, door sills, a wood brake level, shock mounts, etc. (got tired of typing it out).

I don't think there is anything inherently wrong with Tim's torque curve utilizing two GT1554s.

I also don't think there is anything inherently wrong with most single GT2560 setups as far as torque is concerned.

we are all that guy. piggybacks = false economy

like big pictures much?

First off, good luck. My twin turbo build thread was deleted by the previous asshat administrator. Parallel turbos have been done before, I wasn't the first either. I think I'm the only one that's still around though, and putting down respectable numbers (I think the other one used two volvo turbos and put down something like 220hp at 15psi). I think I packaged everything pretty well too, pretty symmetric and clearing A/C & P/S. I've never gotten around to doing something pretty with the airfilters though, but my IAT's are low anyway.

I currently use two GT1548's, the older setup was two GT1544's. My torque curve sucks comparied to single turbo setups i've built. I built it only for a fabrication excercise and to "be different". For much less effort and money you could build yourself something that performs better.

Or you could buy my TT setup for the right price, it's coming off this week so I can test my newest single turbo manifold & downpipe.

I still want to do a sequential setup some day. I have a few things modeled and am certain it could work. I think a V8 swap would be a better use of currently my limited budget...shit i could build a nice 5.0 with just the price of a new 2871 & 2554. Maybe someday someone with enough money will want me to build them a sequential.

nice dampers, lol.

Thats not even Tim's newest torque curve. He's at 234 now. Tim is the blue line:

And his hp graph is nice too. 287hp
