Is ported Intake Manfold Right for me?
I have been thinking how to get the most power out of my stock evo 8 over the next 6 months. i have a turbo back exhaust br o2 housing, and a intake and that is it. I am going to order a upper intercooler pipe with a stock bov or the tial qr bov with it, Now this is where my question come in. I know there are gains to be made if I get my intake manifold ported and get the 65mm throttle body. But will the gains really help me with my car, or should I wait till I get a bigger turbo and port the exhaust manifold and some other small parts. ANd also does Buschur by cores for intake manfolds
you need to list what fuel you're using or plan to be using..
things that come to mind asap are
BOV = because the stock is a boost leak once boost is raised it will hurt performance and efficiency of entire setup in general due to working the turbo harder to make up for a leaking bov.
If you want to go with tial, then clearly you need to change the upper pipe with the bov at the same time.
manual boost controller if the car doesn't already have one.. im surprised if it doesn't.
lower pipe because its cheap to change.
do a boost leak test & turn boost up and retune it.. should yield decent gains.
want more? then do the cams.. a good quality cam will really bring the car to life with a good retune.
want even more? then start porting things to make them more free flowing such as ported intake manifold, tb, exhaust manifold, etc
just the ported intake mani and tb alone will pickup 20whp+ easy.
of course you'll eventually need to address fuel once you start out flowing the fuel system as well.
and dont forget a good core FMIC such as a garrett 3.8" core will really help keep the air cooler and yield more hp.

I want to run e85 but wont do that till about spring once the summer blend is back in ohio. thinking of doing a double pump so i dont need to up grade later . 1450cc injects everything. i have thought s2 cams just not sure what way to go first, maybe find a evo9 turbo?

e85 is the easy way out pretty much..
address the additional fuel required to run e85, change the parts that leak during high boost and get major gains even without cams or fmic upgrade etc.
single walbro 255 will support you up to near 500 on a dynojet with e85. 1450 are not a bad choice.

thanks im just going to start slowly buying parts. i have an ebc in the car but thats going to be changed out for a mbc. i also have a wideband and boost gauge in the car

Definitely grab an intercooler. This will keep your tune consistent and allow you to run more boost and timing with a cooler AIT. The 3.5" looks like it would support your goal perfectly. Any questions, let me know!
Thanks!

My Goal At some point is much higher number around 600 but i dont have the moneyto go crazy so i will look in to intercooler as well as a 9 turbo or a hot side. maybe port the exhaust manfold. and e85
If your goal in the long run is 600 why bother with getting the hot side for the turbo? Why don't you optimize what you have now, and then when the time is right take the plunge into getting bigger better parts to support that.
