hey guys

so im new to the whole turbo setup on our cars and just had a few questions. i'm planning on getting the rrm kit which i know is tuned for 7-8psi. once i buy the kit i was planning on upping the boost.

my question is what is the most boost our car can handle on stock internals?

also if i put in arp head/main studs, eagle rods, and a higher compression piston then what boost level would i be able to attain without completely destroying the car or blowing my crankshaft to pieces?

if anyone knows where i could get best prices on those parts that would be awesome as well.

 

hmm... should've changed the title... oh well these are my questions

 

Tranny first. Engine later. Your tranny wont hold more than the 7-8psi that rrm supplies with their kit. The engine will hold more, probably about 10psi IIRC, but even then you would be putting tremendous wear on the engine and you probably wouldnt be able to run it safely for that long. But yeah, tranny needs to be built first or else your car wont be going anywhere fast.

 

You can't go with PSI as a determining factor. The engine can only hold so much HP and TQ not psi. If you have take 2 turbo set ups at 7PSI you can have 2 very different HP/TQ outputs depending an a number of various factors.

 

=( this is such a turn off for our Automatics

 

Not necessarily the Ripp kit is holding 300WHP with no issues.....and Hackish will be adapting the reflash for that kit.

 

Ok so fine ill probably throw a tranny cooler on it as a precaution then so realistically what is the limit without having to end up pushing my car home?

 

Sounds good cant go wrong with that.

 

hackish is working on a reflash for the ripp kit?

 

Oh, sorry. I was thinking in terms of the RRM kit and how much power it puts out because thats the one Raikiri is planning on getting.

 

I've looked at the Ripp kit and found that mechanically it's very well engineered and very well put together. Unfortunately we all know how tough the RA ECU is to work with so the only thing it really needs is bigger injectors, a map sensor and a reflash. I just need to find a local guy who has one installed.

Don't feel bad because the amount of power an automatic can handle as it is, is still enough to satisfy most. Also like the manual transmission, you still have options to reinforce it, albeit expensive options. However, if you become a power hungry beast, then you are going to have to pay to turn your car into one as well. And when you think about it, how much power do you really need in a front drive car?

@hackish - It never occurred to me that you would have to find people with the ripp kit locally in order to make this work. Thats unfortunate since not that many people have em, well that get on the forums at least. Hopefully there are some lurking around where you are located. Good luck.

 

well like oncloudIX said dont feel bad
but u can improve ur tranny and engine and i will run like a beasty but it will be kind of expensive
i saw a guy that have an automatic ralliart here in this forum and wow it runs like shi...

by the way can some one answer raikiri questions?
cuz i am interested in the answers

 

rakiri I've been trying to figure out the auto tranny control routines. I believe changing these can really help the shift firmness and probably improve the longevity of the transmission. There is no way to really know what it will take before it starts slipping. I'm not an AT guy so I don't know what's really required to beef them up. The 2.4l engine is a bit of a torque monster and it's torque that kills these things so maybe coaxing the AT to downshift faster would also help because it would keep the engine torque down a bit when you really punch it.

i have an AT turbo rall but mine is right now at 8 psi and the tranny is still doing well, but a friend of mine is running an auto lancer at 19 psi with 358 HP to the wheels and he work the tranny, acordding to him he change some gear ratios, clutches, he change the tranny "converter" and "plaquio" the tranny. I don't know you guys say that in english. It is like drilling wholes in the tranny's insied in order to permit more oil flow and the gears feel a lot stiffer and stronger and there it better cooling and loses are reduce. Don't really know the cons but when you are driving an AT car with "plaquia" transmission every shift feels really hard and causes back pain and headache sometimes...hahaha...but is worth because he has a 358 HP AT lancer...now he is putting some nitrous to boost faster so i'll update on that
