Default Build up questions... am I missing anything?

I am gonna do a light build on my 03 wrx. here is what I am going to be adding
-Grimmspeed ported exhaust manifold and crosspipe, and uppipe
-vf48 ported by grimmspeed
-cobb 3" bellmouth catted dp
-considering a grimmspeed ported intake manifold
-TiC composite TGV deletes
-DW injectors, about 650-750 cc
-STI TMIC
-walboro 255 fuel pump


its currently got some unknown aftermarket turbo inlet, and a lightened flywheel with stage 2 exedy clutch. I got it compression tested a few weeks back, and got 148-150 on all cylinders.

I am also considering a water meth kit, maybe an electronic boost controller, and a lightened crank pully.Is an upgraded oil pick-up needed? and also what about an intercooler water sprayer?

you will find out if you are a tune would be a good start. talk to a tuner and they will tell you if that will work for them since its in there hands for the final output result

You don't need the intake manifold, exhaust manifold, or TGV deletes. A ebcs is a good idea. A intercooler water sprayer will do almost nothing unless you drag often. E85 is a better idea than water meth.

Any reason your going with a vf48 instead of a 16g variant?

I'm guessing he's from Canada since his local tuner is Airboy (the local tuner in the Calgary, AB area). E85 unfortunately is not an option here.

OP are you on WSC?

Yes, I am in Canada. we dont have e85 up here, the best we can realistically tune for is shell vpower 91 as husky 94 isnt readily available once you get out of the city and into the mountains. I already have the tgv deletes, so i am going to install them. I chose the vf48 based on availability and my budget for the build. I was under the impressionin that using the ported and coated exhaust manifold will help for spool thats why i was considering it. as for the intake manifold porting.. its going to be off and figured it was worth doing. I havent been able to find any real reviews on it once people have installed it so kinda on the fence.
I was considering a maxbore throttle body service which is better for flow that the grimmspeed porting as maxbore takes the plate out and opens up the whole thing and makes a new plate where the grimmspeed porting only tapers to the throttle plate.


Yes Im on wsc pm me if you have any questions

I ran the Grimmspeed intake mani, exhaust mani, tgv deletes, and phenolic spacers on my wrx. The one thing that you'll notice the most is throttle response is greatly improved. Power wise your still going to be limited by your turbo, but the vf48 is a wonderfully cheap used turbo. You'll def like the new found power. Just up to you if you want to spend the extra money on pnp work.

Check out awdpirates.net I know Fort Collins isn't super close, but we meet up every month or so. Check the "northern CO" thread.

with a light flywheel...a light crank pulley may not be a good idea unless your tuner knows how to alter the tune so it wont throw false misfire codes

forget the intake manifold...but DO port the throttle body and smooth off the plate and the 'axle'....a dremel works great for this....or get a ported tb from grimspeed

get 750 injectors

get the ebc

inspect the oil pick up and replace it if you even think it may be an issue

and get all your exhaust coated...turbo blanket...and wrap the dp!!!!

the proper splitter and a jdm sti scoop are essential for the bugeye if you are gonna keep the tmic!!!!!!
the stock bugeye scoop is almost useless...the jdm sti one is NOT if used with the matching splitter

if you are gonna do water/meth then there is no need for an ic sprayer

i would also get a 'genone' grill as they reduced front end lift on the bugeye....my bugeye was SCARY at speed until i changed the grill and put a lip on it

h6 rear brakes are also one of the BEST EVER bang for the buck mods for the bugeye....boneyard parts can make it a VERY cheap mod that REALLY helps the shockingly weak bugeye brakes, and the h6 mod would be one of the first mods id do to any new to me 2.0 that i would come into posession of, no doubt

I thought I was getting false misfire codes from the flywheel and replaced teh coild packs, checked for air leaks only to find I had a bad #4 injector and washed my cylinder. I dont think the cyl wall got destroyed. Im going to change the injector and see if I can get the compression to come back.

If i have the light crank pully AND the light flywheel.. why would that cause more problems?

I think if my engine ends up being ok, Im going to gasket port match the IM myself. I was thinking of maybe going with a maxbore throttle body bore out. I think it bumps the diameter 8mm. it also includes a new throttle plate.

Why 750's over 650s? I was told that 06/07 wrx injectors or sti pinks (565cc) were plenty, but I was going to use 650's for that little margin of future adjustability. wouldnt the dc on 750's be too low?

EBC... its on my list. was thinking the grimmspeed one is maybe the best one.

I was gonna use the killer b pickup if i can find one for relatively inexpensive. is the windage tray a necessary add on when doing the pick up or just a nice to have?

I am looking into some local powdercoaters for exhaust coating as there would be a lot of stuff getting treated. I can wrap the pipes once I get everything. I have lots of heat wrap.

I saw scoop and splitter combo somewhere and now I cant find the link. I think it was $450 though... grrrrr

I am still reading up more on water meth. my local tuner has had good luck tuning aquamist kits... so that is likely the route i would go if i get one.

i have never heard of that grill. how would a grill and lip prevent lift? isnt that stuff jsut cosmetic?

for the h6 rear convserion, does the booster and mc have to be changed or is the stock stuff enough?
