that has nothing to do with anything in this thread.

Actually that would be the easiest and cheapest way and you still have an ej2xx.

For 500 I really think you would want a different engine completely, but then again all it takes is money. I wonder what the highest ej20g out there is? What ever it is I bet it is full of rare JDM and one-off parts.

im thinking the JUN Auto ej20g..that thing has go to be near 500..atleast high 400's

I was actually thinking JUN as well, but I know you are not going to be able to get your hands on some of their stuff. Plus prepare to bend over!

you can still get JUN parts pretty easily.

i want thier cams and valve springs

you might eek 500 out of the block but there is NOOO way the heads are gonna do it
i would lean towards there would be so little ej20G left that it wouldn't be called a ej20g

lol!, every ej20g I have ever seen that is making big power falls under this category.

i was thinking of using my ej20g block....but i might think about just buying a built block from crawford and getting a 35r kit from ultimat racing..lol putting like 14k in the motor and turbo built and getting her tuned and seeing what i can do for the money.

lots of boost..

I have an Ej20k pushing over 500 hp,
pauter rods
wiseco pistons
CNC Ported heads supertech springs,valves Ti ret, ext.
oringed block and head , copper head gasket, 14mm head bolts
rigoli stage 2 cams
gt 3542 turbo rotated setup
power fc ecu
50 shot of nitrous
1000cc injectors
upgraded fuel pump
and your ready to go :)

it aint cheap.

500hp or 500 whp (600ish crank)?

300hp/L is allot to ask for

500 awhp!

i believe i would just do a usdm swap ad built it.

I want to be there the first time you launch it, and break all four axels and your center diff because you forgot to cryo treat everything in your drivetrain. All 500awhp is gonna do... is break ****.

Contact tonyrigoliperformance.com (http://www.tonyrigoliperformance.com.au/) and see if they've used a ej20g and what they got out of it.

You would need rods and pistons. Would go with Pauter rods, and maybe JE pistons. You are changing the rods and pistons so the best thing to do would be to bore and stroke the motor. A knife edged 79mm crank instead of the 75 and go atleast a couple of mm bigger in the bores to pick up some more ccs. You could go all the way up to 100mm+ to make it 2500cc and more. I have put 4.040" pistons in the 2.0 blocks before with some sleeves. No problems. Factory sti 2.5 short block would be a cheap alternative. Not as good but still works. Cosworth main and rod bearings. Would also get a cosworth oil pump. Mild head port and polish. SS valves with some springs. A set of decent size cams. 1000+cc injectors, and a big fuel pump. Add a -8 fuel feed line from pump to dual feed fuel rails with a fpr. Use the stock fuel feed line for a return. Keep the stock ej20turbo manifold, and add an uppipe mated to a T66 turbo. 3"+ turboback exhaust. Dont forget the management system. I would go with AEM unless you have the budget for a Motec. 4 gm ls1 coils and a good tune. You are there!
Its all easy stuff. Just costly!!!

It doesn't really matter because it would take the same thing to make a ej205 500whp. The key is a large bank account.

It doesn't really matter because it would take the same thing to make a ej205 500whp. The key is a large bank account.Yes, thats true,but, when you have the knowledge you can run faster with less money;)

Have a look here: http://andyforrestperformance.co.uk/4436.html

He is one of the uk's top Impreza tuners and his own Newage Impreza STI 5 Type R makes 556Bhp (UK BHP values) Throughout 2004 this Subaru held the uk record 1/4 mile at 10.52 seconds to 136 mph.

There are quite a few UK EJ20's pushing 500Bhp and one or two pushing 600Bhp. Will see what I can dig out and post up :D

Definatly gonna break s*** with 500awhp.

Ummm well pretty much any well built car from Roger Clark Motorsports.

Firstly the Gobstopper is like what? 850BHP? It's using ported version 3 heads.

Then martyp1's car. Using a stroked EJ20G with P1 cylinder heads. It's doing like 550BHP. EJ20G is great block.

RCMS has done a few of these. They just don't post here.

cheers

Obviously you'll need to build the motor. As far as turbo selection, for 500whp you'll be looking at a gt35r.

would u be better off using an ej20h with the 20g manifold?

You'd be better off with an EJ257 honestly. Cheaper anyway.

You really just want the EJ20G shortblock and pair it to some better heads.

cheers

poorman

You could also do the ej207. There's a few guys around here that have some true 500whp ej207's, some on the stock block.

But with a 2.0l pushing that kind of power it'd be a very good idea to get some head work done. 30psi at 8k really needs it.

Check out this thread. (http://forums.nasioc.com/forums/showthread.php?t=842346&highlight=ej207+gt35r) Keep in mind that in order to run a gt35r, it'd be a very good idea to use an sti 6spd or sti ra 5 speed. You'll need the short gearing with that huge turbo.

so is it safe to say at least 300 whp is obtainable from an ej20g or ej20h with minor mods? and anything more then that requires a newer motor

Is that a stealth bomber?

Is there anybody out there running ej25 sohc/dohc with an ej20g shortblock and intake.
ej25 heads ported ,cam's,in place of the G's (compression?).
could these heads get you closer to 500hp?

Incredible...isnt it?

i run 60psi all day long

In your tires?

In your tires?

nah.. 15psi in the front, 10psi in the rear, then 60psi on my td04.

its just all in the tune, my emanage blue holds up pretty well.

See the Driver's Image WRX.

In his fuel lines :lol:

have you considered a 22t for this? more tq and overall hp is achievable with this block.

i dont want to start a flame war its just my 0.02

kike_ej20, is that your car?

What rear fender flares are you using if it is? That car is sick, seam welded and everything, wow.

yeah that car looks gangster as ****.

wow, thugged out for sure.

STi swapped ej257. with minor bolt ons(less than $2000) and a retune, you'll easily see 400 wheel TQ and 350 hp. thats a stupid easy start. thats stock turbo, stock TMIC, stock ECU,stock inj., stock cat back, get the point? it's newer and better, and subaru is proving it day after day(via our need for boost).

OH YEAH!/\/\/\/\/\ thats on pump gas too! ;)

and everyone once thought the evo was best bang for the buck. who's getting more than 130 wheel TQ w/o new turbos, TMIC's, etc., etc. on their EVO? NO ONE!

i just bought a WRX swap. it was too good to pass up. i will now be looking for a 257 for my OBS for this simple reason.
