I am a newbie and I hope to be purchasing a Lancer soon. (ES automatic) If I do get it, I would like to go turbo, and have done some reading up on the RRM kit. I just wanted to get some info from people who are running the kit now on stock internals. How much boost is the IC turbo kit for autos running and has anyone blown their rods or pistons at that boost level? If I were to get that kit with a few other bolt-ons like cat-back, RRM header, and throttle body, would it be a safe and reliable daily driver without having to go with forged internals? Thanks for any and all input.

 

guru del i belive is running 7-9 psi...stage 2 is in testing...so be on the lookout for that

 

Your ability to boost more and detonate less is basically determined by your ability to control ignition timing, and to flow fuel. If you can flow more fuel then you can slightly oversaturate your AFR, effectively combating predetonation (knock, ping, detonation...whatever you want to call it). The same goes for tinkering with timing. On stock pistons/rods I wouldn't even try to run more than 9 psi personally, but if you can flow enough fuel so that you're not knocking, there's no reason why you couldn't squeeze a little more pressure out of the turbo on stock internals. Given the states of most peoples' fuel systems (my own included until I fix my problems) I wouldn't even try it beyond what RRM is doing right now. I'm not saying it's not possible to run more boost as they're doing it now, I just wouldn't do it for reliability reasons. One lean spot and you've ruined your day, week, month or year. And trust me, that's no fun.

 

Thanks for the info Hobie. If I get the turbo kit, I wouldnt run more boost than RRM reccomends. I wouldnt be trying to build a Viper killer, just a reliable daily driver that can surprise a few people when I wanted to have some fun. Do you know of anyone who has had problems with the standard boost level that RRM reccomends for their kit? If I make such a big investment, I would want the motor to last for quite a while.

 

If the kit's installed properly it's highly, highly unlikely that you'll have any problems with it within its recommended boost range. I can't think of a single person who has off the top of my head.

 

yeah havent heard of anybody having problems bc of the amount of boost the rrm kits are preset at. they keep it conservative so there isnt much to worry about.

 

[sidebar] Hey Im selling my Lancer OZ. I could save you some money and you could get that instead of your ES (Iam In Ontario too) PM me for info

 

Thanks again for the info. Im beginning to feel a little more confident now about the stock internals ability to handle the pressure. Right now, Im keeping my eye on RRMs stage 2 turbo for automatics to see if they can hold up to that.

 

Danno, where are you in ontario? If you're too far away, then Im not interested!

 

I dunno if I'd be that confident. Pressure aside, it's detonation that's the real problem. They pistons are not strong. I don't mean to give that impression. All I'm saying is, the more fuel you throw into the mix, the less detonation, and the lower your chances of detonation. Theoretically with enough fuel you can combat detonation up until the point where your vailtrain becomes the issue, not the fuel.

 

i agree, i wouldnt be a believer except i drive around every day in my stage 2 auto hehe.

So far all is well and 3000+ miles on this stage. I run 91 octane so it isnt like i get super fuel like you east coasters either. I also wouldnt run over the 9 psi mark on stock internals.

Pretty much everything has been covered but I just wanted to put my opinion in here

 

Only issues I have had with stage 2 and 9PSI is a blown exhaust gasket (the one between the up and down pipe). The OEM exhaust gasket..the one that goes between downpipe and header and downpipe and cat will blow out. You will get a nasty exhaust leak and the car will run like crap. Won't hold boost, etc... My friend is going to try and fabricate some gaskets out of copper.

 

im running a stage 2 kit from ripp mods at 11 psi and 65 miles to work each way with no prob ................
