I am nearly done with buying all of my mods. Looking for everyone to critique what I have and what else I should get. Mind you this is a year-round daily driven car in upstate NY. (we get cold winters and lots of snow).

Here are the power mods I have sitting around to go on my stock 03 Evo:

Ported FP Red turbo
Buschur turbo-back w/ test pipe & magnaflow muffler
1200CC injectors
Buschur dual-fuel pump
EPM 02 dump
HKS 272 cams
Fidanza Cam gears
Megan Exhaust manifold. (should I port/ceramic coat?)
Perrin FMIC
RMR FMIC piping
RMR intake
Forge DV
Fidanza Aluminum flywheel
ACT 2600 clutch
Tein coilovers
To be tuned on stock ECU with E-85 by CBRD

What am I missing? Should I get valves/retainers, Fuel pressure Regulator, Fuel rail, or anything else? Are any of my planned mods going to bottleneck me? Should I change anything out? Is this clutch going to hold? Is there any other cheap mods I can get that will significantly add to more HP while maintaining driveability?

What kind of WHP and 1/4 times should I be at with these mods?

Thanks for your help guys

 

switch to a ported stock exhaust manifold

 

Which will have better spool/higher top end?

 

looks good except coilovers, cams, and manifold I would have gone a different route

 

Elaborate for me. These coilovers let me choose with the push of a button how stiff the suspension is (EDFC), the cams are aggressive but dont have a too much of a crazy lope or idle, and the manifold.... well it was cheap .

 

go back to the stock ported manifold, the one you have will most likely crack, get some cossies M2s or gsc S2 cams, and I don't know how that intercooler compares to others, either way thats a nice build.

 

I've heard videos of the M2's and S2's idle and it aint pretty... anyone have real world experience of these cams vs HKS 272's on an Evo 8? Also, what is the spool/power difference?

Thanks

 

def. go back to stock manifold... i have a megan and i hate the >>>>> out of it.. just because it looks cheap after you install it and it heats up... and i would have changed mine back to stock but its a pain in the... to change out the manifold... other then that s2 cams... i heard the Fidanza Cam gears... don't hold up to well but i could be wrong other then that you look good...

 

Yeah the Megan manifold is a toss-up, but it is cheap and I've heard both good & bad about it. It was worth the cheap price, I think.

Can you explain more about your thoughts on the Fidanza cam gears? You would think any cam gear would do, since they are not a high-stress part on Evo's..

 

Teins are just not a good coilover from the evo. Also it does sound cool to be able to change everything with a push of a bottom but its really not that easy. It will mess with your alignment and handling. I would definitely suggest going to robispec if handling is a major concern. HKS 272 really are not aggressive at all. You are giving up substantial horsepower with those cams. The ones i would suggest you would need springs and retainers though. I would suggest that anyway since the FP red performs awesome at high rpms. I would go with juns, kelfords, or gsc s2's or FP's. Then Kiggly springs and retainers. Megan just makes sub par products (just like tein). I would get that stocker ported and jet coated from buschur. If you really want to splurge get a full race but I don't it would be cost efficient to spend a grand on a manifold.

 

Like most everyone else, I would opt for a more radical set of cams, and if possible a P&P cylinderhead, as well as a ported TB and a ported IM or a V2. Top it off with an EMS(in spite of the cold weather) and a Buschur or Ivey tune. Otherwise you are on beam.

 

dont try to get cheap mods like you said if you do dont be surprised at your numbers....in my opioion your on track but i think you should swap some parts out for buschur parts like....4" race IC.....the cams are gona hold back power to....go with a more aggresive cams

 

Are you by Albany campus? Is that where you're getting you're E85 from?

 

What everyone else has said about more aggressive cams. Aby gained like 20whp in the midrage IIRC on his 8 and Green going from GSC S1 cams to Cosi M2's. A set of springs and retainers from SuperTech won't cost you that much and will allow you to run the higher lift safely.

 

QuarterMaster twin disk and not that ACT 2600 junk
Twin Disk comes with its own flywheel so you wont need an aluminum one either and I dont even think a 2600 would support the hp level for an fp red on race gas assuming u make decent #'s
Port stock manifold dont use megan
Kelford or Jun or gsc s2 cam with springs/retainers
Port ThrottleBody
Stance coilovers instead of megan assuming you didnt already purchase if you did nvm or even just get springs
Buschur IC Pipes/intake w/ mini battery might even wanna get a Tial BoV - will be fine on stock ECU
Cam gears might not be necessary but if you already have then put them on
