2008-2012 Lancer turbo Set-up
So you're ready to go Turbo?
For those of you that want to go turbo right now and not wait another second RRM offers their one off turbo kit. While costly it appears to be a decent kit, I'll leave it at that since I'm not in the business of cutting throats. I will say this for $4300 usd i could build a fully built block, a turbo setup and still have gas money left over. I just read a post regarding a turbo and a gentleman made the comment " that until you build it yourself, you'll never understand how it works ". I would like to tip my hat off to you sir that is so freaking correct. I have compiled a list of parts that are readily avaliable decently priced and affordable that could, if you spend the time build a awesome turbo kit. While new parts are nice i highly suggest cutting cost where you can and buying genetly pre-owned stuff. Bov's, injectors, manifold, inter-coolers are all fine examples.
I have already heard the comments such as "buy and evo", "Swap an evo engine",etc,etc. While for the rich folk that maybe fine, but for the working stiffs umm not so much. You can boost a manual transmission 2.0 safely to around 9-10 psi. Rule of thumb is no more then half of the engines crank horsepower to be safe. There is one exception in this case CVT's you may get away with only 5-6 psi. Now i know what you're thinking " man why even bother". The answer is simple for $2500 name one other part that will give you 50-70hp? NA bolt ons will get you so far, But at what cost? The answer is up to you in the end. Nobody ever said we had to this is just an option for those that want it. Below is a small list of parts. I have listed several turbo, piggybacks, gauges,etc. Look threw find your budget and build what you can afford. Most of us don't have $3000 laying around take the summer buy piece by piece and in the off season put it on.
First thing you need is a decent parts list here is a collection of parts that will work for the 4b engines. Some parts need minor mods to work but nothing serious:
Manifold: Evo x and Ra. Bolt up work just fine. Any after market evo x or ra can work too.
Turbo: RA is a single scroll turbo. The stock wastgate is safe for boosting a lancer. The evo x on the other hand runs a stock 11psi. A little dangerous for a new tuner. 7-8 psi is safe on the 10:1 compression with proper supporting mods.
Injectors: Ra and evo x bolt right in and do the job well.
Intercooler: Ra and evo x fit just fine.
Intercooler piping: You can use either stock Ra or evox. Both will require removing the battery and putting it in the trunk ( use a sealed gel type battery EG; optima)My thoughts on this are dont be a wussy buy hard piping and do it right.
Oil and coolant line: Tapping the oil pan is the best for the oil return. Using a steel 10 an weld in bung. Oil feed can be found on the front of the block under the pcv valve. It's a hex head plug. Once unscrewed provides plenty of fresh filtered oil for your turbo. The coolant is simple. On the throttle body is a coolant line feed one side into the top of the turbo, the one side into the bottom completing the path for coolant to run.
Guages needed at first are simple. Boost and a/f wideband. Aem is the way to go!
The things you will run into using evo x parts. The downpipe needs to be modded to fit. The lower intercooler piping will need to be modded to fit. That's it.
All that being said this job should cost no more than $2000 and 1 full weekend of work. A little dyno tuning and your done.
