Hey I have a 2003 evo 8. Black. So far I have a ssqv and a cone filter. Not an intake just the filter. I am spiking 13psi and holding 12! I am asking for ideas to make my evo faster! I would prefer bolt on! People have told me about stock turbos with only bolt on parts doing 350 whp. Please help thanks!!

 

Wait, are you serious? Only 13 psi? Stock is 19 spike. You should start by making the car healthy first.

 

In before close.

P.S. Search.

 

Get that pos BOV off your car and get a evo 9 stocker, change your spark plugs (your BOV prolly caused these to gunk up) and put an intake and a turbo back exhuaust. The get a nice flash and youll be happy as can be.

 

1. go to the noob section and read. https://www.evolutionm.net/forums/ev...faqs-forum-61/
2. you sure you're only hitting 13 psi? if so, you have a leak, or an improperly working boost gauge.
3. lose the ssqv. you dont need it, and its only hurting your cars drivability
4. yes its entirely possible and pretty easy to hit 350whp on bolt ons and stock turbo.

welcome to the forums.... but definitely not a good way to start out bro. hope you got your flame suit on

 

get a exhaust and a tune.

 

you dont need an intake. your filter and adapter are fine for your goals. you wont be running a speed density setup so dont bother with anything beyond this.

 

In before close but yeah 13 is way too low

 

First, do a boost leak test and check to see why you are only running near wastegate pressure. I bet you are actually running WG pressure and your boost gauge is a bit off. Search, you'll find lots of info on how to do those things.

Second, lose that POS BOV and put on an Evo IX diverter. I'm sure you'll miss the whoosh noises but, your car will thank you.

Third, spend some time reading through the forum. You've got a lot to learn about your car. Most of it has been discussed already. There is tons of good info on how to make your car more powerful you've just got to look for it. In your case it sounds like just getting it running right will be a significant improvement.

 

In...

Yea fix the boost. Sounds like you're running close to wastegate pressure. Stock boost spikes 20 or so, then holds around 17

 

DC Sports downpipe + exhaust, tune at 21-23psi, no need to change stock intake.

 

If you are recirculating the HKS, it should be fine. Turbo back exhaust, lower intercooler pipe, MBC, fix boost leak, tune.

 

ouch, yeah get the car fixed first before trying to make it faster.

 

the 2 mods on the car are exedy stage 3 and a hks ssq.. future upgrades are piaa wheels and a mr body kit.. hah...

 

Okay, i think you got enough help now, haha.
I was going to post up on everything what was needed to say, but it's already been said, ha.
