The intent of this thread is to gain insight on internal modifications. Specifically what the most cost effective route for my goals will be. I consider myself pretty knowledgeable when it comes to bolt-ons (choosing and installing) but, not so much on internals. I would love to gain knowledge through your experience and suggestions in this thread. I have always been most interested in increasing power output of my wrx but, at the same time am timid because of the fear of catastrophic failure. I would rather have overkill in the area of combating this type of failure than go on any farther than my current stage 2+ set-up. Currently my car has 68xxx miles on it and everything discussed in this thread will be assuming when it hits 100k the engine is still in good working order. I estimate that at the rate I'm going it will take me about 5 more years before I hit 100k. My goals are 350awhp on e85. anything north of that would be great but, not required. Rather than just do the timing belt service then I would like to pull the engine and rebuild it to handle more power. I will be removing the engine myself but, am not comfortable with the rebuild unless I really learn a TON between now and then about it. Rather than modify my car any farther now, I will be hoarding parts as finances allow for this build. This is where you guys come in! This may seem like a large list but, keep in mind the amount of time I have allowed to acquire my goals. without further ado here's my list.
Forged pistons
connecting rods?
Bearings?
Machine work
AOS
ID 1000cc injectors (I plan on going e85)
parallel fuel mod
aftermarket fuel rails
20g turbo?
gs tmic, splitter, i/c hoses
sti 6speed trans
r180 rear diff
dccd controller
new clutch (oem) and possibly lightweight flywheel
oem water pump
oem timing belt and tensionersis
Studs?
gs thermostat
killer b oil pickup and windage tray
Head work?
stiffer engine and trans mounts
gaskets?
cobb ss with kartboy bushings
This list is not set in stone and I am open to suggestions. I only want what I will need for this build and not a bunch of extras. Remember this is a budget minded build. Now for the questions. What brand, size of pistons? Do they usually come with all hardware (rings, pins, exct...) If not what will I need? What kind of machine work will I need done? Will I have to increase bore? Should I get coated pistons? Connecting rod suggestions? What if anything will have to be done about/with the crank? What about bearings? Will I need any head work done? What kind of gaskets should I plan on buying? Do i need aftermarket head studs? Will my current walbro 255 support my fueling needs or will I need to step up? I would like to keep my 5x100 wheels, hubs, brakes so, what is the most cost effective way of doing this with the r180 and 6 speed swap? Axles?
Now Drop the knowledge on me so I can get to pricing my build and sloooowly buying parts!
