Turbo Corolla...??

[jelly53]

Just out of curiosity I was wondering if anyone out there has put a turbo on their corolla. If so, what numbers are you pulling??

There have been a few people who have done the conversion. Usually with either a 4EFTE Starlet engine (1300cc) or a custom made turbo set-up on a 4A-FE. The best one I've seen is pnyk33's. The last time I heard he was pulling 300hp.

You can view a video he made in this thread:

I'd love to whack a turbo on my 5A-FE one day, but one of the main reasons why I bought my Corolla is because of the fuel mileage it gets. Most of my previous cars have been turbos on fairly high boost and I wanted something that didn't cost the earth to run but had a bit of passing power when I need it. I do miss the thrill of boost however, just not the costs involved .

as far as my understanding of turbo's goes is that, it actually makes the car even more efficient..... when you are not driving hard......or am i wrong?

That is true in some situations, but certainly nothing that I have experienced with all the turbo cars I have owned (although I do have quite a heavy foot). Generally speaking, more air = more fuel, and more fuel = more costs involved (especially since you have to run the engine on a higher octane fuel). Admittedly, newer cars are designed in such a way that they use a relatively small amount of fuel compared to a turbocharged car from the 1990's.

If you constantly kept the turbocharged engine at low rpm's, then you will theoretically use less fuel as you don't have to change down as often to get enough power for acceleration.

But at the end of the day, it all comes down to matching the appropriate sized turbo to the engine you're using, and of course, how you tune it. If you can afford to buy a decent turbo setup, then you probably can afford to lose a few MPGs. That's just my opinion on the matter however .

well said. although my way would be to just get a turbo kit and put it on the same engine....not rebuild the whole thing up..... its a tough little engine.....

I had my stock unaltered 4afe with a nissan t25 at about 180whp reliably on a custom built setup. I used fuel/ign management, and had a good tune with much larger injectors. Was a blast and I was getting 35mpg on the hwy. In the city or track days that significantly dropped as I was having fun.

sooo tempted.

I want to get rid of my kit as I went 20v again. Its all sitting in boxes. Do you have a/c? Willing to take on a little project? The turbo seals failed, but I have a line on another used t25. Im wanting to part with it as a kit, and as long as it goes to a good home id be willing to make a deal. It was all custom, used an oil filter relocation kit to move the filter and take the oil feed, it ran beautifully.

Kit is:
~Oil pan with return on it
~Relocation kit with hose and heat wrapping
~Oil feed line and fittings
~Aluminum Intercooler and aluminum hard pipes with silicone fittings and bov
~Vaccum block and lines
~Emanage ultimate with patch harness, greddy map, greddy injector adapter, greddy a/f adapter, and center console (blue) notched out with bracket to steath mount greddy where the airbag computer usually sits (I have no bags)
~SS Manifold and 2.5 mandrel ss downpipe (gets you to just behind cross member)
~Full 4afe m/t harness modified with resistor block and tails setup for dsm bluetop 450cc injectors (injectors supplied with it)
~Civic aluminum half rad and upper hose supplied.


Notes:
~The tune on it was good and reliable, but some time on the dyno may net you more.
~Needs a new Innovate LC1 for the autotune and monitoring, wiring is there to connect it. ($140-160 online)
~I have a VDO boost gauge that could go with it and would recommend an oil pressure gauge.
~With the different turbo, the Coldside outlet piping may need a little aluminum work as with the original turbo I couldn't clock the outlet.
~I didn't have a/c and not sure probably wouldn't clear with how the outlet on the coldside was clocked orignally, reason why I ran the civic halfrad. The turbo should clear the a/c compressor but I won't promise anything, I could try mocking it up but that takes time which id rather not bother with unless someone was very serious. None of the intercooler plumbing would be an issue with the a/c as it goes around.

If your interested pm me and we can talk. I don't want it sitting here collecting dust or I may end up putting it on my gf's LE..
That is that.
