Please Help

Ok, I'm fairly new to the turbo scene but I've done a LOT of reading and searching the net. I've looked for my answers but theres sooo much stuff to look through. I was just hoping if you guys could answer a few questions for me. alright here goes nothing:

1. I'm in the process of getting an Injen air intake. I also have a 1st gen bov coming in soon also. it's crushed (I heard that it's better to get crushed than uncrushed, is that true) what will i need to use both?

2. I'm also going to get an MBC. what is a safe psi to run with a stock car?

This is all I can think of right now. I really appreciate everyone's help.

Your going to need either a 1g flange or an upper intercooler pipe with a 1g flange.
Crushing can help it hold more boost if done right.

If you get an injen pipe just make sure it has a bov return tube on it.
You also need a boost guage before you go turning up the boost.
I'd start at 13psi and see how the car responds and work my way upto 15psi. But thats just me.

Some say you can run 16psi but I wouldnt recommend it unless you rewire your fuel pump.

i agree with boostinawd, unless you can monitor the a/f ratio with an a/f gauge, or you have a high capacity fuel pump, you shouldn't run the boost at anything higher than 15psi or else your a/f ratio may be to lean and youd fry your engine

no turning up boost til you have boost gauge!!!!!!!

you need either a new upper intercooler pipe flanged for a 1st gen blow off valve or a adapter to run the 1st gen blow off valve

15-16 psi is fine to run everyday but get a boost gauge

the injen intake is good intake, looks great and did i mention get a boost gauge...make sure to get a k&n filter with that intake

you will notice a goodpower increase with those mods

I would prefer you get a greddy upper ic pipe and a type s bov instead of 1st gen. and please do take everyones advice on gauges. knowing whats going on inside your engine is more important than how fast it is.(if it doesnt run u aint going anywhere r u?) a safe psi is usually around 14-17 on the stock t-25. Start out small though like at 13 like boostinAWD said and move up. Fuel management will be important too because when you increase boost your ecu automatically increases fuel pressure, you dont want to put too much stress on your pump.

Go to DSM.org and follow the mod guidelines- It will save you a ton of trouble. BTW- 16 psi TOPS on the stock turbo- GET A BOOST GAUGE!

Have fun, good luck!

Agreed! Do a little more searching(tuning guides/steps). There are tons of sites that have them and they all seem to follow a similiar path(little variations)
This site has one, look at the top of this page and click "tuning guide"
http://www.roadraceengineering.com/2gupgradepath.htm
http://www.buschurracing.com/stage_1.html
ETC......
Want to feel significant difference in performance on limited funds? Start basic
1. **BOOST GUAGE**(not for performance but for safety)
2. K&N FIPK(why buy an intake pipe if your still sucking through a restrictive box)
3. Upper IC with 1G BOV
I did just these before I bought my exhaust and WOW what a difference(can you say night and day)
Research the parts you want and make sure they will compliment each other(do not buy a part just because of the Bling Bling factor of a name) You could end up having really purty, high dollar engine parts but you're getting spanked by people that still have money in their pockets.

Should I get a boost gauge? J/k. I have an autometer phantom boost gauge and I'm currently in the market for an A/F ratio gauge. Any suggestions? Also, my peak boost is already at 12 psi. I do have the wastgate solenoid mod done.

 

[CBgst]

I would suggest and egt gauge. What I uderstand is that air feul ratio gauges aren't correct. I also heard that the jumptronics digital gauge is good but I think the site says it's not accurate at wot. Maybe someone else can give you a better info on this.

 

[VBGSX]

After adding the above(earlier post) parts, my peak boost increased to 14.5psi and I did not remove the restrictor! As far as the a/f guage, it will only give you a rough idea what you're running(not including HIGH dollar wideband units). In my oppinion most(autometer,etc) are not even close enough/safe enough to trust or tune with. Get something that is tried and true....egt gauge. There is a ton of info on this site, on how to tune by it's readings plus it''s a great safety device.
