Hope that helps.

I am in the proces of TC my VX220 Z22SE (or Opel Speedster in Holland).
Just a fun light car with decent power. Bin theredone that with big power Nissans...not anymore.

Setup:

Garrett T25G Turbo (Nissan180SX)
VXR 470ccinjectors
TAT Uprated IC (from VX tubby)
2.4 intake manifold
OBD-tuner software
Some bits and bobs...

Should push something like 220ish whp ~ 260 bhp. Hope stock clutch can handle this.

Exhaust manifold is in the proces. Since limited space in the VX this is a DIY job. Waiting for the SS flange I bought over here.
Oil feed is from one of the 3 plugs below the ex.manifold. Allen key 6. Thread is M12x1.75.
Oil return by drilling the oilpan and tap a plug in there.
Water feed from the drainplug fromthe waterpump => NEED TO KNOW THREAD! so I can sort my AN lines lol.
Water return can be tapped into Therm.housing. Some tap it back into the expansion line.

If we can help each other,you're welcome!

Yesthink so. The last "12" is the lenght of the bolt if I'm correct. You can ad some crushwashers for a good fit.
Or get this:

That blue fitting looks like a nice idea, rhwn use some goodridge hoses or similar.

This is a nice supplier:

Will the 2.4 take boost? Would in not be best to just fit a Z20NET intake, there a direct bolt on.

TFD

US guys have taken them up to 16psi. I will only run 8-10 psi max. on stock block.
Belgian guy had one on his DBilas setup pushing 0,78 bar/12 psi.
Well... for now. Allready thinking of making my own intake from a SR20 intake I have around. Wouldn't push too much on the plastic manifold....

Is there any reason why you dont want to use the NET turbo manifold?

TFD

Apparently the 2.4 flows better. Not my own science, but reading some US forums.
I was hooked by the idea that the 2.4 has shorter runners and therefor moves the powerband up the rpm's. A T25 on a 2.2 has enough down low so was looking to spread the powerband as wide as possible. Z20NET seems to have a smaller plenum?
