Thread: I'm Very Happy

Mmmmmm.... Turbo.

Ahhhhhh.... Intercooler

How much boost will it develop?

I can inderstand your excitement. I have been looking for a suitable turbo unit to retrofit into my Jeep. If anyone has any ideas about where to start for a 4.0L Jeep motor, lemmie know.

Aaron, are you fitting that yourself? or getting the local motor shop to do it? If your doing it yourself some pics would be nice of the installation..... I would be interested to see what is involved....

should be damm fine with a turboed rotor...

My thoughts exactly. I was actually quite giggly the rest of Saturday night.

Looking at a maximum of 10PSI. Actually, this is the stock turbo and intercooler from the turbo RX-7. The intercooler is good for 10PSI when it is top mounted on the engine, but since I will be front mounting it, 12PSI should be possible. However, that will be really straining the turbo, and not to mention the engine.

As far as your jeep goes, why not supercharge? I would think that it would suite the engine better.

I'm fitting it myself, of course! . The turbo bolts up with just a simple adapter, and after that it's just a little piping, and swapping the injectors. And the little things like a boost guage, oil and coolent lines, etc.

I will be documenting the whole process, because I want to write a how-to for my website.

Aaron, you make it sound all soooo easy..... maybe its time to turbo-charge my swift eh?


hrm..... maybe not..

Actually, I have a feeling that it is rather easy....

-remove stock exhaust manifold
-bolt up adapter and turbo manifold
-attach turbo
-have exhaust shop make a downpipe, weld to my aftermarket cat
-tap into heater line for coolent, return line to other heater line/other hose
-tap into oil cooler line for oil supply/return
-install intercooler (either in front or behind rad, haven't decided yet)
-measure air pipes and have exhaust shop mandrel bend stainless tubing
-connect turbo to intercooler
-remove upper intake manifold, swap secondary injectors for larger units, install higher pressure fuel regulator
-reinstall upper intake
-install boost guage (run tube from intake to guage on dash)
-connect intercooler output to intake, check clearance
-decider where to put blow off valve, cut hole in intake pipe, weld in valve

-start car, warm up, FLOOR IT!

See, couldn't be easier...

maybe its time to turbo-charge my swift eh?

Didn't they make a turbo Swift? If so, then it can't be that hard...

they may have...... GTI swifts are fuel injected 16Valve standard, but not turboed. I have seen swifts that have been turboed, but im sure they were fuel injected as well.

A better mod for myself (if i was going to) would be to install a recoed GTI engine.....

Aaron, dont forget that the computer you have in the car is not for turbo engines, you will need to change your computer to the RX7 Turbo one or just get another aftermarket unit. Its not going to be cheap though.
After installing the turbo your fuel/air mapping changes and your current ECU wouldnt know how to handle it.
Engine might run but at high revs it will be really lean.
Changing the injectors might help a bit but they wont gona do much as you ECU wouldnt control them properly.
There are ways you can do to correct this but i guess it would be easier to get another ECU.

Yeah, I'm aware of the ECU problems. However, raising the fuel pressure and swapping out the secondary injectors basically cures the problem. There are supercharged NA RX-7s running 10PSI of boost on stock computers, with only a higher fuel pressure and larger injectors. A boost sensitive pressure regulator will also go a long way.

Believe me, detonation is foremost on my mind. It't the quickest way to kill a rotary engine besides overheating.

If I am feeling creative, I may add two extra injectors to the upper intake, and make a BasicSTAMP based controller to run them off of the boost sensor....Sort of a cheap Super AFC or the like...
