OK folks been reading as many build threads as possible.. Lots of decent threads to read and get hits as for how to go. I am thinking of building a street monster that in time will be a 2.2 stroker.

My ride is a 2011 -12 LoL buying in June. I am going to break this down in too 3 stages passably 4.

Stage 1
Intake piping, intercooler, manifold, and header, down pipe, test pipe and the works. Muffler and cat in the scrap bin..Then get a 91 oct tune.

Stage 2
Cams Kelford stage 3, and head work port polish gasket match, over sized valves and so on might even play with doing some valve stem work. Head stud/ main stud/rod bolt And a Garret GT turbo to be picked out soon. LoL Retune

Stage 3
Sleeves 2.2 crank rods pistons trans work and center diff work. Stand alone.

I have left some things off the list that are no brainer's clutch fuel system BOV waste gate and so on. I will at this point be running E85 im sure.

Again I am new to this sport compact world. I come from 1000whp chevy V8 land.

 

You will need a bov before you put a larger turbo(just cuz it was mentioned in stage 3) . For 500 whp you could also consider a stock fram turbo like an fp red. This will also allow you to use a ported stock exhaust manifold which flow amaamazibgly well.
I have a built 2.0 and with a red and bolt ons and injectors I will easily get over 500

 

I will have to look in to stock frame turbos. As I want to spool up sooner then 4000 rpm.

 

Not really necessary to build the motor or do anything in the head for 500whp/400wtq.

Start with all the bolt ons and do some more build thread reading, it will serve you well.

Also, don't buy anything garrett for the evo X.

Depending on the fuel you have access to your turbo selection will change.

If you have e85, a bolt on turbo (fpred/ef3) will get you to your goals with the right supporting mods. If 91 oct is all you have, just go straight to a full turbo kit from AMS, ETS, MAP (in no particular order) and get a precision 5858 sized turbo. Or if you want to spend some buck, get the full race 7670 t4 twinscroll kit.

But in all honestly, judging by your steps, you need to read more...not trying to be a dick but you have lots of research to do to become familiar with what is all involved with the X (evos in general too).

 

Just got done reading UT yours and Hollywoods builds. I am gonna run a E85 and E99 maps. I will be getting a hold of Hollywood about a 3rd emergency back up MAP.

Any one have a link on cams in case I cant dig up good info.

 

cams:

buy gsc s2's or kelford b's/c's. AMS TMPs won't let you down either.

 

I agree with murlo a lot of that isn't necessary for 500whp. However a built motor just to be on the safe side is a good idea. That's what I did for piece of mind. As far as the valves go almost all the research I've done shows that the head on the x's flow really good and oversized valves could actually hurt more than help. I'd recommend a built bottom end, some cams, ported exhaust manifold, and all of your bolt ons such as fmic, dp, test pipe etc. some 1300 injectors and e85 will go along way as well. spool up by 4000rpm isn't bad at all either. I was just posting in another thread about how I was worried about lag at first. Once I got my red installed and actually took it for a drive I ended up wondering y everyone made such a big deal about it and I was coming from the faster spooling fp green.

 

Plus 1 for the fpred turbo with a built bottom end. You can hit those numbers and have a solid car.

 

I should also add that I came from a V8 background a few years ago (Chevelle, several Camaros, etc) and I was very worried about turbo lag, but having built a WRX, STI, and now an EvoX I can tell you that fear goes away with driving experience on these little cars.
