an idea would be a search, honestly though its all been covered, not sure of your goals. give us an idea.

an unholy beast of an engine would be a 2.5 liter with forged pistons and Cosworth heads IMO, that would be a setup good for 500+whp easy.

you might also get new rods too if you want reliable power
i guess some peoples fininite <sp?> element analysis shows that the rods arent near as strong as everyone thinks, granted there are people making 700hp with them...but if a rod goes...the entire block goes...and thats a spendy fix

Swap in an STi shortblock or just get an STI engine, then go with a 20g turbo setup with a nice aquamist WI setup and run that with 30% methanol 70% water, tune it and be happy,

But if your starting with an RS be ready to fix a bunch of other things after aquiring such power.

With the ease of finding OEM turbo engines now, anybody who embarks on an FI build of an NA engine is beyond foolish. Do a swap and be done with it.

MY BEAST LIST:

-EJ257 Shortblock
-Darton Wet Sleeves
-Forged Pistons (8.5:1)
-Forged Rods (w/ COBB coated bearings)
-Cosworth Heads (w/ oversized sodium filled exhaust valves, springs & titanium retainers)
-STI Cams (regrinded)
-Cometic gaskets
-ARP Head Studs
-850cc Injectors
-2006 Ported Intake Manifold (w/ larger custom mounted throttle)
-Pulleys (of your choice)
-GT35R
-STI: Crank, Oil Pump, Water Pump, Timing Belt, etc...
-FMIC
-Standalone ECU of your choice (AEM, Tec3, MicroTec, Wold 3d, etc...)


I might be forgetting a couple of things but basically you have a 600-700 WHP engine with this setup. Ad some NOS and you might see 800 WHP...
Of course you better throw in a 6M STI transmission and reinforced axels.


hope this helps.


pd.- I'm currently working on a "similar" setup for my RS

Everything else was right, except the injectors are too small for 600 hp. There slightly bigger than 400hp.

1-Cosworth is a brand... for more info http://www.fastwrx.com/cocyhe2tu.html
2-A GT35R is a Garrett ball bearing turbo with nice top end power... although I would probably use a GT40R... more info http://forceinductionracing.com/gt40r.html

Just to clarify, 850cc's IS ENOUGH to get to 600-700 whp... Trust me I might not have a guru tittle under my name (cause I'm to lazy to post) but being member #56 gives me a little credibility

Just because you did a swap,dosnt mean anybody that doas somthing diffrent is foolish! Your foolish for thinking your smarter than others by putting a bone stock engine in your car over a pro built motor and paying about the same heck that gets two Take that SheeeeeeeeeeT back too the conversion forum...you get no love in the AFIP!
