Planning ahead for EVO X build

I know this is a ridiculous long thread but hopefully a few people take the time to read it and give me some advice. Thanks in advance.

I wanted to get thoughts/opinions on my plan for an Evo X build. Let me know if you think other parts would be better suited for my goals or if you think I should change up the order that things are done etc. I've spent countless hours reading, planning, and daydreaming about this build.

I will be purchasing my X in Jan/Feb of 2012. I'm undecided if I should buy used or brand new. Buying used would obviously save me a bunch of money, but I really like the leather and sunroof available in the 2011 models. It's hard to justify spending an additional 10k - 15k though just because I want a sunroof, the appeal of a brand new unmolested car is nice and I'd love to pick out exactly which options I do and don't want. But I'm not sure if it's worth it when clean, low mileage, well kept cars with mods I would be spending even more money on anyway are available. Maybe you guys will sway me one way or the other. Most likely I'll be getting a GSR in WW but the MR's tranny would be nice for traffic and long drives.

Objectives: Over 2 - 3 years build a 600+hp street car. I want to have as quick spool as possible. I want to maintain drive-ability. I want to address all areas of the car and have it be well rounded. I plan to do auto-x, track days, canyon runs, meets and cruises but it will also be my primary/daily driver. I will have a backup/beater car for bad weather and when the Evo is under the knife. I don't care about what class of SCCA the mods put me in because I won't be competing for points or anything but If there are any required safety stuff I need for events I will get that (ie fixed buckets, harness bar but I really don't want to put a cage in). I'm not trying to build a show car and don't want to have the most jdm tyte parts and fitment. I want high quality functional parts no cheap megan or godspeed stuff but I'm also not willing to spend ridiculous amounts on jdm brands because all the cool kids are doing it. I want to be able to hang with the best in all venues street, strip, & track. I've got some ideas for a slightly different direction for the aesthetics than most X I've seen, car but I want to keep some surprises.

So here's my plan, I want to do mods together in logical groups/order so things work together and save time/money. Also each group is a reasonable amount of money to save up and there will be a few months in between where I will enjoy the previous group while saving for the next. Steps 1 - 4 will be done immediately and the rest over time according to budget with lots of seat time, regular maintenance etc in between.

Step 1: Obtain Evo X
Step 2: Detail and change all fluids to mobil 1, redline, motul etc. (Need to research detailing tools and materials)
Step 3: Perform all common fixes: fuel relay, master cylinder, mud flaps, rain guards, interior rattles etc.
Step 4: Electronics - I figure that getting my entertainment stuff setup as well as tuning/monitoring should be my first group of mods done together. I can't stand the look of gauges all over the place and I've got a plan for custom mounting this stuff so I want to install all of it together and then get my first tune.
Alarm - Undecided need to figure out what will work with turbo timer, and have remote start, 2 way pager etc. Any recommendations?
Carputer - Revosys X500.1
Tuning & Monitoring - Evoscan GPS
Radar - Passport 9500ci
Turbo timer - Ark Design STB
Boost Controller - I'm planning to eventually have an ewg setup, so I don't think ecu controlled boost is an option. Undecided
Throttle Controller - debating Ark Design, Blitz or D1 Spec

Step 5: Fuel - I figure that since I'll be living in the bay area where E85 is readily available and that having proper fuel is an important supporting mod for everything else setting up the fuel system next would be a good step.
Buscher Double pumper
DW 1300's (big enough for 600+ hp on E85???)
AMS Fuel Rail
AMS FPR kit

Step 6: Transmission - With all I'm reading about the diff pins and the stock clutch I figure this is what should be done next.
Exedy Twin
Act Flywheel
Shepard Built Trans with higher final drive
TWM Short Shifter
AMS Shifter Bushings
Weighted Shift Knob Probably Flossy

Step 7: Wheels & Tires
I want to go a different direction than most Evos, I'm going to get HRE, ADV1, or DPE Wheels. They will be either mesh style with hidden hardware or very concave multi-spoke monoblocks. Which is great because I get to choose exactly what size and offset. I'm thinking rolled fenders 19 x 10 +20 with 275/30 tires. What do you guys think about that size and fitment? Although I may go with 18's so I can get Falken Azenis in 275/35
Step 8: Brakes & Suspension Part 1
Robispec KW Clubsports
Whiteline Roll Center Adjusters
Brake Pads, Rotors & SS lines - Undecided, need to figure out what will be best setup for my daily driven, weekend warrior.

Step 8: Aesthetics Part 1
Undecided Front Lip, painted headlight housings, roof spoiler, shorty antenna & Some Vinyl Wrap in a few places
Step 9: Bolt-Ons & Power
I want to use all stock location parts so everything bolts up and I can do these over time (not necessarily in this order) instead of in a group like the other steps. Also want to keep a somewhat low profile.

Injen intake (its carb exempt, and hopefully helps when CHP pops my hood)
ETS 3.5 inch FMIC
Synapse BOV recirculated
Intercooler Piping - Undecided ETS, Perrin, Buschur or AMS
Perrin Complete Boost tube kit
Upgraded Radiator - Koyo or CBRD and hoses Samco or Agency Power
ATP divorced and transformable downpipe with Tial External Wastege
AMS High Flow Cat
Cobb Cat Back
Exhaust Manifold - Undecided Stock replacement manifold probably Full Race or ETS
Turbo - ATP Garrett GTX3076R unless someone can convince me that the FP black or another stock location turbo will spool as fast and flow enough for 600+hp on E85
Step 10: Suspension Part 2
Sway Bars, Control Arms, Strut Bars, and chassis underbracing
Step 11: The Head
Cams - Undecided Valve Springs, retainers, port n polish the head intake manifold and throttle body all at once.
Step 12: The Stroker
I figure by this point it will be time for a rebuild, I've also considered doing this as one of the very first steps, not sure but that's why I'm making this thread to get opinions. I may get an AMS 2.2 Short block. Really unsure about the details of this part of the project but it will get all ARP hardware upgraded bearings the whole nine yards when I build the bottom end. I want to have faster spool and more low end torque but don't want to go 2.3 or 2.5 because I'd like to keep the higher revs for top speed.

Step 13: Aesthetics Part 2
Body Kit, Custom paint, engine bay cleaned up, and some interior dress up stuff

^^^^ Thanks took me forever to write this thread, hope it wasn't too much to read I actually omitted a bunch of stuff. I've been trolling this forum for a while and I learned a lot with my current beater project S13 240sx KA-T. Most important thing I learned was to have solid objectives, realistic goals and budget, to buy quality parts from reputable people that are meant to work together and never ever keep and work on your project car at your dad's house if you don't live there and he's not into cars at all.

Thanks, I'll definitely be doing more specific research into the areas where I have questions. This was mainly about laying out the big picture and hearing what others think of it. Making sure that I don't miss anything major, I'll be taking my time to carefully reconsider each part as the time for purchase/install gets closer.

Definitely a plan that will translate into an awesome build. Keep this updated, I will without a doubt keep looking back to follow what you have done and be very interested in hearing what worked well and what you ran into problem wise!

Very well planned out. Your car will not be some thrown together, modded mess when it's done. This is how a well built car starts!

Thanks!

This is exactly why I'm making this plan, of course in life things rarely ever go according to plan and I've still got a lot of work to do on the details. There's still a bunch of small stuff missing from the list like boost control solenoid, catch can, interior stuff. I really want to review my plan with some guys from a shop (most likely fftec since I'll be living in the bay area and they will be doing any installs that I can't do myself and the tuning)

I really want to minimize lag so maybe I've chosen a hp goal that is too high or a turbo that is too large we'll see. I may get halfway through and be really happy with the car and just keep it how it is but I doubt it. Another big consideration has been trying to keep the engine bay and the setup somewhat stock looking because I do like the "sleeper" affect and I'm really worried about CA smog and cops. I've got to figure out what the real deal is with that because I see so many built cars from CA but I also see so many horror stories about going to see the ref etc.

I am trying to plan it out so that I don't buy things twice, like an intake that no longer fits when I go to a bigger turbo. But I've also never owned or driven anything with that much power or with a really stiff suspension setup. I'm making a plan based on what I think I will enjoy etc. So we'll see how it goes.

very thorough thread-

there are lots of different ways to achieve a goal with these cars-

as your needs change/develop- let us know if we can help- with the radiator or otherwise

cheers

Ik its not in your first couple steps, but I bet you get an exhaust or intake sooner then you anticipate.

I didn't read everything but I don't see any plans for doing your short block. You are really going to want to do that.

600whp on an FPblack or EF4 from MAP will be possible. Honestly those turbos should flow more than the ATP 3076. Unless you get a GTX3076 get the black/EF4.

Get a test pipe rather than a high flow cat and I'd go with 18's since you're tracking and what not. I didn't know the Injen intake is carb? I thought AEM was the only carb intake.

Thanks, I'll be in touch. I've been considering lower/different power goals so maybe your turbo upgrade will work. I also really like the intake heat shield you guys make.

The plan for the short block is a stroker kit so yea you missed that, I'm debating if I should actually move that further up the list and then bolt all the other stuff onto the built motor.

I've thought about FP black and am still debating, part of me just wants to be different than what everyone else has and the gtx I think will spool quicker which is a big deal for me.

Yea you're probably right, I should move intake and catback into that first batch of immediate mods before the first tune. The stock X is definitely too quiet.
