DIY twin turbo Z
 

Hi everyone
Z is slow, so I'm fixing it :D
I'm not sure about my end goal (750~850whp on 98 octanes)
I don’t know what I'm doing :D I learn as I go
Anyway to the part list (for now)
- X2 g25 550
- X2 40mm Turbosmart GenV Wastegate
- Intercooler (not sure\custom?)
- DW400 Fuel Pump (maybe)
- ID1300X Injector
- id750 fuel filter
- mazworx VQ35DE exhaust flange (custom manifold)



these things not small not at all they barely fit in

I came up with a way to know the available space for turbo and manifold using cardboard
You don’t need to remove the engine, but it will help

Match cardboard to the car and cut it starts at the engine mount

Keep doing that till you cover all the area you want

Now find any sheet metal and cat it to cardboard shape
I find this :D

Now weld them to the mount

Now mount it to the engine

You can also do that to manifold flange if you want to work somewhere else

For now, I'm waiting for wastegate to finish the manifold

Sub’d see if this will get finsihed

Not sure what to say, but you go ! good luck with your project.

It will I don't know when but it will
my welding skills need some work

I want to see how this turns out. Curiosity got me.

We already know how its going to turn out :icon17:

(Not Hating) But the quality of workmanship is pretty close to ghetto imo :ugh2:

700+ hp.

Good Luck!

When he gets done with this project. He might have a degree in backyard engineering. I'm going to be grading him on-line.

subbed

Is that above or below redneck engineering?

That depends on the Redneck. LMAO....

If it requires 3 or more rolls of duct tape. It's above,

Me too. I'll bite. I started body work this way. I messed up a lot, but I learned a lot.

All I can think of is to be careful how close those turbos are mounted to the body of the car. Dont forget that the engine shifts around. Those snails might slam into the body and put stress on the manifolds, causing a crack/leak.

Good luck! Definitely some outside the box thinking here, which I like.

The best of luck with your build it will be trail and error doing a custom build yourself to get the fitment proper take your time and give him some credit for the attempt to do his own build. Those turbos create a lot of heat as well definitely try not to mount the turbos where they will not rub against the subframe and/or any body parts. Any damage to the manifolds and it will be inevitable you will have to disassemble everything.

To be honest, I don’t have a lot to post about
I'm still stuck at the driver-side manifold
just received wastegates and some other parts that have nothing to do with the turbos

You going to wait for long time :D im very slow

for the heat I'm not sure should I ceramic coated or go
with turbo blanket

anyone know how to resize the image ?

I normally use this

thanks I'll try it

You need to use the same diameter of straight pipe as your elbows. This will make it better for your welding.

I started this in 2009.
