HSG that was meant to be, but hasn't yet

[brendanshort]

My 5th gear is not "hard" to get in, but to stop it from crunching you need to take your time while shifting. I had my gearbox repaired a few years ago as 2nd was completly stuffed.

what is stock boost for HSG?

 

[dj_konix]

i would say 8psi but never really been anywhere near stock boost in mine

 

[MattL]

It's either 8 or 10psi.

They will handle 14PSI without any upgrade but a tune is suggested.
If you want to hit 18 you should invest in a fuel pump, tune and a decent intake and exhaust.

20psi is stock for around here :lol:

I spiked to 24 PSI accidentally on the old Hyper Auto. It ran 20 without any hickups.
the new RVR will be running 22 - 24 PSI though I've got all the addons required to support the additional boost.

CLuTZ and many people here know this but just saying it again, stock 4G63 shouldn't go over around 18-20. You can do it, but I wouldn't suggest it

Ask brisvr4 about it

 

[CLuTZ]

You can run 30psi, if you have the setup and tune for it.

I ran 25psi through my old VR4's stock motor besides cams....

 

[MattL]

Fuel, tune, cams, many things influence it all.
Most people just "dial it up" and wonder why they blew their motor
