Quick Question...

[Anquetil]

Hiya, a quick question. Whats the maximum amount of boost you would run if you still have the stock exhaust (decat) and intercooler on a WGNC34?

Is there a level where the amount of boost will exceed what can flow through the stock exhaust?

Thanks

stock turbo should be safe around 10.

i put a 3inch turbo back on my car and it ran 10psi on its own

The intercooler can handle the most your stock turbo can make safely (10 -12psi) but if you have an S1 it would be a good idea to upgrade to an S2 (R34GTT) smic. Also get a high flow panel filter for your stock air box.

I don't really know the answer to the exhaust question but I would not recommend running 10 -12 psi through your stock exhaust. You could probably by-pass your solenoid to run 7-8 psi all the time but a 3in turbo back exhaust (no cat or gutted cat) should really be your first mod. As TJ says that will give you more boost straight away.

I ran 12psi on stock zhorts with a fmic for a while and its fine.
