Post Question for the turbo gods out there

I own a MY93 1.8L and the engine is in fairly good condition. No leaks or problems. I've been told that it should be safe to run a small turbo on my engine with a little bit of boost. I'm am just wondering if this kit would fit my engine. The parts included are these:

rhb52 INI turbo - great shape
turbo headers and up pipe
Brand new turbo crossmember
h20 pump and gaskets to clear header
new thermostat for the new h20 pump

I'm sure that many of you have seen this currently for sale by bluesaint. I think that it would be pretty safe for my car. I just need to know if it will fit my car. What other parts would I need to get? Any info on this will help me a lot.

Thanks

The kit should fit fine, as all EJ series motors share about the same block. I won't gurantee this however. That turbo setup fits on EJ25 na motors, EJ22 na and turbo, EJ20 turbo parts fit on EJ25 so it would therefore fit on EJ20 as well. Logic states it should fit on the EJ18 too. I don't know if its been verified, but I think you would be ok.

You will need a legacy turbo thermostat housing, oil and water feed/return lines, misc silicone hoses, and a custom downpipe that uses a standard turbo flange. Thats about it.

I am currently doing this setup on my car, and I have the turbo waterpump, thermostat housing, and thermostat in so far. The engine crossmember will be going in on the 17th most likely (I think I am goign to need a 3 day weekend for this one).

[EDIT] changed from an EJ serious motor to EJ series.

I have a '94 1.8L and can tell you that it will fit.

The main concern is the 4 port exhaust manifold(2 ports per side) type which the 1.8L has, so no worrys.

A turbo will work with you powerplant. Don't worry if you blow it up. Used 2.2s are pretty easy to find.

I know JC Sports has turbo'd 1.8s before so you may want to discuss this with them. They could probably give you an idea of what works and what doesn't work.

The only way you'll blow it up is if you have the wrong a/f ratio and ignition timing.

The cylinder walls on the 1.8L is a little thicker and the rods are the same ones found on the earlier WRX models.

If you force more air in there you will need more fuel, that is a rule. Electronics include Fuel Controller, Ignition control, knock prevention, and gauges. You will also have to run the highest octane pump gas to improve reliability and definitely change out your clutch. I would also look into brakes.

This is probably kinda a stupid question, but what kind of gains would I be looking at after it is installed? Reading some research specs for my car say 110hp stock. Nothing too major that would make me wet my pants I would guess because it's a smaller turbo right?

IMHO
I wouldnt bother with a 1.8l Think Id buy a 2.2l block and build that up for turbo instead. Lets say you get 50% extra (WAG) on that 1.8l block (seems somewhat the limit before cost go up in the scooby world) that'll give you, 110+55=165? Of course you can pull more out of it, but then you're probably looking at ecu replacement, etc, etc. Of course a 1.8l running 25# of boost would be interesting though.......

So are you saying that I could possibly get about 50% more hp with this kit? Provided that it is tuned properly.

I have a couple more questions. First, what does WAG mean. I know, I know, newbie question, but I'm clueless.
With this kit and nothing else, could I beat cars like the civic SI in a drag race? If I added some more mods such as intake, exhaust, plus other, cheaper mods, (nothing like a tec-II or anything up there in price), would I then be able to beat them?
Next, would this kit be later tranferable to a 2.2L block? How much are the 2.2L blocks going for these days?

Thanks

R33,

IMO, don't waste your time on the 1.8L. It has already been done by JC sports. They have turbocharged it and managed only to get around 140 hp or so.

The stock 2.2L will generate around that much power stock and that is without any mods.

I would either get a newer '98+ 2.2L or get an older Legacy 2.5L motor. You can find these kind of engines anywhere from $300-$800 on the average.

Just make sure your existing tranny is compatible with the new motor. Some of the older 1.8L trannys had a smaller shaft.

What electronics will I need to make sure that I don't mess those things up? Will I also have to upgrade my fuel system to accomodate for the more power?

If you do decide to do an engine swap for a 2.2 or 2.5 you should talk to Joel Gat. He swapped a 2.5 in for his 1.8 and can probably offer some guidance.

Sounds like a plan to me. You can then take the time to build a bulletproof 2.2l block.

Yeah, you can put a turbo on now but a turbo won't do you any good unless other parts are durable. For example, the 1.8L tranny is weak and has a smaller clutch which probably won't hold much. So what's the use of the turbo if you can't get that power to the ground? There are very few high performance clutches out there for the older 1.8 trannys. The one's that are out there are the race 4 and 6 puck versions which aren't good for daily driveability. Not to mention that it costs over $400 of which could go towards a new engine/tranny.

You will also need more than just a "turbo kit" including a whole new fuel delivery system(fuel controller, pump, injectors) since the 1.8 had small injectors and pump.

Economically and Logically, it doesn't make sense to me. But do whatever makes you happy, that's how we all learn things in this hobby.

Check your pm.

Pm'd you back Aspen.

Thank you to everyone that has offered advice on this matter. I think that I have chosen a route that would be better in the long run so I'm not going to buy this turbo kit right now.

Thanks again everyone.

What do you guys think of this. I get the turbo, fit it on my 1.8L. Run that until this summer when I have a chance to get more money, get the 2.2L block, transfer everything to the 2.2L, build up the engine a bit while it's not in the car, then replace the 1.8L with the 2.2L eventually.
I want this turbo on my car now, even if it doesn't do a whole lot. I need something to quench my thirst for a little boost. So I would have a turbo car now, get the 2.2L soon and then turbo that.

Would this be a good idea?
