I have a 93 Pro with 120K on motor/trans and I'd like to throw a new turbo on it from a 90 eclipse. This turbo is brand new. Anyway, I was thinking I could get away with like 6-8psi of boost and be fine on the engine/manuial trans. I will be replacing the clutch later and thought that I could get away with this setup until I get a new motor on rebuild this one to handle more boost. Thoughts?

I think if you use the exhaust manifold from the GTX and fabricate yourself a new flange you could use it...

didn't the 90eclipse/talon use the garrett t3 turbo..? i don't know

wow!!...what a loaded question...what does your exhaust look like...is it smoky,are you blowing/burning any oil??..which protege engine?? 1.5L or 1.8L???are you going to intercool the intake charge??? and what are you going to do to fit the turbo to your manifold ?is this the original clutch on the car??...when you have over 100K on an engine and you want to increase engine stress 50-60% you have to think...how was this engine treated for this 100,000 miles...was it abused,was it maintained well,did overheat often,any oil leaks or other probs ? think a little on your next question and youll get a better answer

1.8L, it will be intercooled, currently leaks no oil, doesn't burn oil, was well maintained and not abused. Runs like a champ, just looking for more power.

The turbo is a T25, smaller than a T3 and much less efficient. Its a turbo used for light applications. Running 8psi on it will blow your motor into little pieces if you don't add fuel and control timing. You will need a new clutch as the stock one isn't even good for holding a beer. Also the direction of the compressor outlet has an off curve to it and getting IC piping to route in such a tight spot would be a big trick. There is a reason they sell for $50 on ebay. They are nearly worthless unless you own a DSM.

Macdaddyslomo, you need to chill out and think before you reply. I understand that there are dreamers out there that want 400 hp on their 200k engine with nitrous and a turbo, but this guy sounds like he has a plan. NO NEED to rip on him just for asking a question, totally uncool.

I know for a fact that the turbo on the Talon has a T3 hot side. You can not rotate the compressor housing because of the internal wastegate. However,if intercooler piping were to become a problem, which could be an issue, you can switch to an external wastegate with a custom manifold.

I just did a quick search and found that corksport does have an exhaust manifold for the DOHC engine that this guy has. However it has that T-too-small flange on it... no big deal. t3 flange is about 15 bucks and you just hack one off and put the other on. or you could buy an adapter for about 100 bucks from HKS, but then you may run into clearance issues.

The turbo on the stock talon (14g) is not as bad as you may think it is. I've seen 300 bhp out of that turbo. I don't think that's his goal though... running a t3 14g at 8 psi should be fine on just about any engine, providing that you are running the correct supporting modifications.

Things to think about:
- You need a stronger clutch, and I hope your tranny holds up
- You should upgrade your oil cooler from that lame tube to something acceptable.
- If you can't fit an air to air intercooler up front, an air/water intercooler is quite simple to manufacture, provides better cooling and is very easy to plumb... it only requires minimal surface area up front for the heat exchanger.

I think this sounds like a Rawkin' idea. I see no problems with it. He said that he was planning on rebuilding his motor in the future any how. One thing to consider... you would want a larger exhaust system to run that 14g, at least a 2.5" from the turbo back, maybe through a highflow cat in there if you to pass emmissions, still very easy to do. Any muffler shop on the planet can make a 2.5" exhaust if you can't do it yourself.

Not sure what injectors your car has or how they are staged. I know it has 4 fuel injectors, but how are they setup by the OEM computer? Do they run one per cylinder (that would make sense and that's what I'm assuming), so they are probably a batch firing setup. the 4g63 that the 14g comes on needs to upgrade to 550cc injectors. You may need to do the same. You won't know until you through a wideband on there and see what your AFRs look like. However, I know that you can add an RX7 MAF to these cars, which takes very nicely to an AFC. With 550cc injectors, an AFC, possibly an MSD box, custom intercooler setup and a 2.5" exhaust, this sounds like a pretty trick Protege.

Go for it TeamSlo!!!

The talon turbo has NOTHING to do with a T3 it is a full mitsu turbo if he is talking of the 14b and the T25 that was on the DSM only used a garret compressor the exhaust turbine was the same as the 14b a TD05H Mitsu housing it says it on the housing if you don't believe me. Also the GTX manifold for the 1.8L on corksport does not utilize a T25 flange at all it is made for a IHI turbo that was on teh GTX to begin with. I'm not knocking you or anything just getting the FACTS straight here. Also 550cc injectors on any Protege would drown it without a stand alone a AFC would not be enough to handle those. I know the stock injectors on my 1.8L FS are only 225cc injectors and they held 7 psi of boost with an FMU fine if he ran 550cc injectors with a AFC, the AFC can only cut the injector pulse +/- 50% so he may or may not be ok but at idle with no boost at the 50% maximum cut his injectors would still be spraying as if they were a 275cc injector which would make his idle very spurratic and possibly flood the engine as stall everytime he came to a stop. My suggestion would be make a turbo manifold make your own piping use a FMU and make a low boost application or instead of a FMU use additional injectors and a controller such as the one found on www.sdsefi.com. I hope that clears a few things up on this matter.
