Default Trying to Boost up my 1.8... for fun... nothing more

So I bought a 93 impreza L, FWD 1.8

I dropped the transmission tonight because it needed a new clutch and starter. I also needs a oil pan gasket and some other minor stuff. its got about 160k miles, body if rough, need pulled on a frame machine.. ect. slight hits to front and rear, door dings.. the works. I have a body shop family owned, so no problem there. and I paid 600 bucks for the car.

I recently installed some HID's. Acura RSX seats (look just like sti seats) Tan leather. The rest of the interior is tan, so the seats looked good. Gonna do a Carbon face plate to mount the radio and gauges and get a NRG wood trim steering wheel. getting some Used Tein coilovers from a friend for free and will buy some Diamondracing wheels 15x8+20 probably. car will be low, streached, and poked.

SO, getting back to the turbo part. Im looking and I can easily find stock 2.0 exhaust manifolds and non catted uppipes. Everything can be had for under 100 bucks if you look in the right places.

Will a 2.0 exhaust manifold fit a 1.8? or should I just weld up a custom uppipe off the stock exhaust manifold?

Other then that, if I keep the turbo in semi-stock location, a wrx downpipe will bolt up to the catback and everything will be quite easy.

Will probably do a oil return tap into the oil pan like you would on a honda if you were boosting that, unless anyone knows a an issue with that, and im sure it will be easy enough to run the oil and coolant feed and coolant return.

Ill also be running a fmic and oil cooler.

for tuning, ill only be running like 5 psi at most, less if I can find the right wastegate spring/MBC combo. and ill just be upgrading the fuel pump and running a wideband. run a water/meth system to richen it up a bit.

Can you tune a 93 ECU with opensource?

So yea.. any advice, throw it in. cant hurt.

search FIRST, then PM!!!


Most guys still on here aren't old school and have only had WRXs or STis. That's why you've had little response. They don't know
RS25.com will be a good place for you to scour parts too.

ej18't' is an old school build that has been done numerous times. You can use the wrx manifold, uppipe and downpipe but will run into issues running the turbo inlet because of the intake manifold differences. It also requires you using a turbo engine crossmember. You can probably still find and old NA turbo kit on here. Which uses the NA manifold and just uses a custom uppipe and downpipe as far as exhaust plumbing goes.

There have been numerous different kids for them. Most were aimed for the 2.5RS engine (fitment is the same) but will come with a large turbo for the EJ18. I know subachad use to make an upppipe for stock turbo use...TD04, TD04, VF series.

I don't know of any open source or eprom's for the early US NA ecu's. Most ran SAFC and Apexi ITC for fuel and ignition control. They also would use a rising rate FPR. Honestly with how cheap a used Link + can be picked up, I'd skip the piggybacks and wire it in.

Impreza2345 is another local (as I'm in MD now but in Va Beach on the weekend) who has run a turbo EJ18. He's on an EJ22 block now IIRC. I took my EJ18 turbo kit off back in 02, before I even joined this site ...I was going 02 WRX engine in my 94 L at that point.

You can easily pick up oil feed for the turbo from the main galley running back on bank 1. Get another adapter from Subaru for the oil pressure sensor. It's already 1/8 NPT IIRC and is easy to access and is close to the turbo.

We have a 1993 wagon that was fwd we recently converted to rwd (hahaha i know rwd, no awd) Anyways we are running an turbonetics t3/t04e. with a top mount and custom up and down pipe. Your in luck having the 1.8 as it has the thickest cylinder walls of all ej series motors exc. the ej22t block. All you do is at the end of the header you build an up pipe to a smaller t3 turbo ( junkyard garrett turbo is the way to go, pull it off a ford thunderchicken/thunderbird. Its good for about 250-300 whp. relatively) then build a bracket off your block to hold up the turbo. Next go to your local junkyard and get a set of legacy turbo fuel rails with injectors and the injector clips. Put those on and get a vortech 12-1 fmu and an apexi safc2. The apexi safc 2 is nice because you can make 2 maps, 1 for high boost and 1 for low boost. You'll need to tap your oil pan or passenger side head for an oil return and you can pull your oil feed from one of the galleys on top of the block. Here in salt lake we run about 7-12 lbs on pump and run 15lbs on 110 gas. Pm me if you want pics.

Hope this has answered your questions. let me kn ow

Here is joejoe's EJ18 build thread running FWD w/ EJ22T heads:

And his youtube channel filled with exciting videos of his car:

I feel like I preach this build every week, he was extremely successful.

You can take this build anyway you would like, with EJ22T heads, you can push insane amounts of boost.

There are a lot of hybrid builds around, I'm sure you can source some more information elsewhere, but here is just a start.
