Default Built EG33 Turbo Aim for 400-450whp Help

Hey Guys

I am selling my car this weekend and I'll be starting another project this summer. I've been throwing around a lot of ideas as to what to throw in there. Originally I was thinking an STI swap or a built ej205 with an 18g or something, but recently I've really liked the appeal of a semi built EG33 with a turbo.
Being swapped into an 93-95ish GF wagon.

So here is the idea, but I'm not sure of the cost yet.

Buy an EG33. Keep the heads stock, pull apart the block.
What internals? ej22t pistons? I was thinking STI rods, maybe better pistons than that?

And then of course, what turbo do I run? Don't want to run something too small so it runs out of juice at higher RPM's But i don't want something too large that it will blow the motor apart. Remember I'm looking for around 400-450 wheel

Then obviously the exhaust/turbo setup is going to be a bit interesting. Does anyone have an idea of what it would cost for someone to fab up headers/upipe?
Ideally, it would be really nice to put the turbo in stock location for a WRX, making it easy to use WRX downpipes and exhaust etc

Also, what is the tuning software used for the SVX motor?


And then after the Engine comes the transmission. I'm thinking doing a STI 6spd drivetrain, for a decent price its a strong transmission, I could get a full setup with axles rear diff etc for about 3k or so


Just looking for a little help on what things should cost and some answers to my questions.
Thanks guys

good idea, look at the E-manage ultimate, they can piggy off the wrx ecu and then run two additional cyl.

i would use an 18g as a turbo. two tdo4's would be nice too.....

ej22 internals will work but you may have to find some custom rods.

svx motors are pretty cheap too

would the 18g be big enough for that motor? It would be sick to rock it twin turbo, but I'd rather deal with a single turbo setup.

maybe ej22t internals aren't good enough, should I go for something stronger?

For engine management I would go with a megasquirt. It will do anything you want and with MS3 coming out you will be able to do individual cylinder trims and sequel everything up to eight cylinders. I mean you have to do the harness anyway so way no do it with a stand alone.

For the turbo I wouldnt go anything smaller than a 35R for that.


The internals are very strong to start with. A few older builds have seen 500whp on the stock motor. For reliablity I would use STI rods and custom pistons with a 9:1 CR because you dont need much boost for 500whp from a 3.3.


Now what are you going to do about the radiator? It must be relocated further frontward or overtop the engine where the intercooler would sit if you have a scoop.

Also the manifold for the exhaust will need attention too. Somehow you need to get the turbo in and doing it in the stock location shouldnt be more anyharder than a STI.

I've heard the blocks are strong, but with that much power I feel it would be a good idea to beef it up, I don't want to have the possibility of it blowing up inside lol. Plus, most available SVX motors already have over 100k miles on them, it would be nice to refresh the inside a bit.

I've been talking to a few about the radiator placement but I need to think about the intercooler setup, not exactly sure how that is going to fit once the radiator is moved forward

As some one who already has a built EG33 PM me please so you do not make the mistakes I did. Hydra has a plug in play EMS. CP pistons makes gas forged pistons, I used Eagle H beam rods. The heads def need attention as they dont flow well at all. Especially on the exhaust side...

Is this going to be a N/A or FI application? Tracked occasionally? Often? Daily Driven?

I'll admit the exhaust side needs work relative to the intake side, but in general the EG33 heads flow quite well for a production car actually.

There's damn near 420 hp worth of airflow potential in the stock as-cast heads. The key is in unlocking the potential. Cams are the best place to start, in conjunction with some exhaust porting.

If you had a budget to begin with, this probably wasn't a built you should try and tackle. Nothing will be off-the-shelf. Cams alone would probably run at least $1500. You could easily spend the cost of your whole RS on the motor.

Got me all excited for a minute to see an EG33 build. I have my doubts it ever happened though.

most people struggle just getting an eg into anything but an svx, and the number of real street cars running turbos can be counted on one hand with a finger cut off

I was thinking about a eg33 or ez30 or ez36 into my wrx when it came time for BIG power. Straight to a standalone to prevent issues. I just think parts are hard to get/make.

My friend is currently finishing up his build on his 96 SVX. He bought a built EG33 w/ custom CP forged pistons, Eagle rods, and Delta regrind cams. Oh, and it's supercharged via a Lysholm blower bolted to a custom machined stock EG33 intake manifold. He's using Hydra EMS for management. It has been quite the experience so far, and it's been quite expensive. It can be done though.

Tryna bump this post again haha, so, to gather everything together at the bottom, the main areas of difficulty/expense are:

Reground cam from Delta
Custom machining head for increased flow, springs, retainers etc.
Valves. Nobody has mention the difference in valve size. What other EJ valves can be used?

Headers, turbo location, porting- all custom. Obviously including exhaust-any logical person would use V-band.
Radiator relocate.
Standalone Ecu.

I’m planning to do a build on one over the winter, any help appreciated!
