Re: CH Lancer Turbo Build

To be honest, if you cant afford the parts from RPW, RRM or even getting henry to mod one up, are you going to be able to afford to replace the engine when this blows.
When I considered doing this from the start, I found a very useful piece from RPW on the 4g94 :

You can skip most of it, but the same basic lines are followed with most engines I would believe, but at the bottom it states:
4. Turbocharger Conversion Package
What more can we say other than your a horsepower and boost Junkie. Welcome to the rest of the world. This combines extreme levels of torque and power, with neck snapping acceleration. It comes at a cost though, increased fuel economy, higher insurance and lots of money. But lets get something clear first.
1. Anyone believing they can effectively fit a turbo kit on there car saftely, properly and legally for under $5000.00 AUD$ is just plain dreaming.
2. These engines in stock form will not handle above 1 PSI boost without aftermarket computer management despite what people believe. 25 : 1 rising rate fuel pressure regulators, larger injectors, piggy back ECU's like Apexi, Greddy etc all these tricks - none work. Don't skimp.
3. 5th Injector systems are something that came and died in the 80's. Quite simply this does not distribute fuel properly to all cylinders, and still does not provide ignition timing adjustment
Do the job properly and although it may cost more, it will last longer, provide trouble free maintenance and be everything you want it to be.
1. For boost levels up to 10 psi can be done saftley on the stock head gasket dependent upon tuning and intercooler efficiency.
2. For boost levels up to 14 psi requires an upgraded decompression head gasket which RPW manufactures.
3. Do not boost above 14 psi on the stock piston / conrod setup otherwise you will learn what a banana conrod looks like.
The 4G94 SOHC engine at around 13 psi is good for around 200kw at the flywheel at the extreme. With forged components you can go up to as high as 250kw reasonably at around 20 psi boost as a good starting point.
Our final advice - if 200kw is not enough for you - the finish reading this page, and instead either look for another car or look to do a engine swap to a larger Mitsubishi engine.
Average price of a turbo kit fitted, installed with a FMIC and Haltech ECU System is around $8500 - $9000.00
a) Have fun with <10psi of boost, you'll blow your head not to long after install. And you wouldn't be able to run that at full 10psi. Seeming the 4g69 wouldn't be a turbo designed engine
b) Reflash really is only for minor mods (eg. CAI, Full Exhaust, Bigger TB, etc, not turbo/charged/new engine)
c) @ 13psi your getting 200kw (not just from the turbo from all of the upgrades [cams, exhaust, cai, tb]), then thats at the flywheel so you'll have less power atw
d)The Price for a decent kit, 9k? say take 1k off if your doing it, 8k?
I went through all I'd need to do, to make sure the engine wouldn't blow it's self to pieces, I came out with roughly 20k for a proper, PROPER job.
And then after all of that, you need to go get it engineered for it to be street legal. If you only do the turbo, you'll be sent back with a big list of things to do that your bog stock parts won't handle with the extra power, in the end companies are there to make money no? so they only supply you with the parts needed to make the car safe with the power and weight on board. IMO if you truely love the shape, feel, etc of the CH ES, then do it, otherwise do what I'm doing now, save, do small things, maybe just rice a little, enjoy the car not turbo'd while on your P's (i'm sure the last thing you parents would like to see their son in an over powered car go straight into a tree) and then with your savings buy an already turbo'd car, which will already have the strength to take a turbo and upgrade the turbo.

im probally gonna go ahead with a turbo project. im more than likly going to buy an ebay kit just to start off. and an evo 7-9 downpipe,
