If you upgrade your exhaust with no cats your boost will automatically rise, sometimes out of your own control. If you get a 3 inch exhaust you will need a FCD and at least a walbro fuel pump. You will also want to port your wg to keep boost lower and then get a boost controller.

 

what I really want to know is if im running 10psi, can I run it safely with my mods I already have and also a boost controller and also an FCD, do I need to have an exaust and all of the exhaust componenets to run 10psi safely?

 

^Bump, please help guys. Any info would help.

 

i had the RB 2.5 DP/MP with stock catback and i was only boostin peak 7-8ish.....most of the time i stay within the stock of 5.5-6psi...but with the RB 3 inch trubo back....boost raises too much..just fun driving it goes up to 9psi.....once it hit 14 for a split second.......good thing nothing happened.....

 

Get an intake temperature sensor.
Install it before you upgrade and get a baseline of what your intake temps are peaking at.
When you upgrade, set your MBC at no more than 7 lbs. Monitor those intake temps and bring up the boost gradually. If your intake temps start getting to high, you'll need to upgrade your intercooler or add WI.
But def get an intake temp sensor. It's a must when upping the boost.

 

You also need to keep in mind that getting more in means you will be pushing more out. So you should consider swapping your exhaust for something less restrictive first. Like someone else said, even if you just remove the cat(if you can--emissions..), your exhaust will be freed up a bit. Better to have more potential from your exhaust than not enough. That way you just dian in with your boost controller without worrying about hitting a wall.

 

ight thanks guys

 

don't waste money on band-aids, save up and get a Haltech or the like.

 

what you mean, how would they be bandaids

 

What's that supposed to mean??
