Ok i am looking at a comparison between rrms stage 1 and the new a2 designs kit with the intercooler kit also. Lets try not bash anyone, but what are differences in the kits? Do they come with different items or are they about the same exact thing? Also i know that we dont know the power from a2 yet just because nobody has bought a kit. But i just started reading around and learning up on turbos and wanted to see what a2 had compared to others and why.

 

Well with A2, you get the 16g and the wastegate is rated at 10psi, I dont know what RRM's wastegate for their kit is rated at. But with 10psi you will get good gains, like 240-250hp for 2500 dollars vs the 4000 dollars with the RRM kit. Also, you get good items with both kits, you will need a SAFC and it's suggested you get the return fuel system if your lancer is 03+ so you can up your tunablity. Also you will need a wideband o2 kit if you want to be serious about tuning because it will monitor your cars Air/fuel ratio and that will tell you if you are too lean or too rich and that's important info if you want your car to be drivable. With all the extra stuff, you will still end up paying less than 4 grand, as long as you look for the best prices on these gadgets. I plan on getting the A2 kit myself and I already know where I'm gonna get my safc and wideband from and that's here= http://www.extremepsi.com/store/customer/home.php
That site has good prices on the electronics they sell. I am going with the A2 kit but I know RRM's kit is most likely better and has all you need, you dont need to buy a fuel controller at all, they provide the piggyback and that kit itself looks good and easy to install.

 

Well i thought 7 psi was the most to run unless you upgrade the fuel system and then you could run 9 psi? Is a SAFC just another type of fuel unit? such as a piggyback or a emanage? Also if i bought a wideband i wouldent need gauges such as an egt, air/fuel, exhaust temp, and boost gauge?

 

You can run 10psi max, anything higher than that is a no. And yes, you do upgrade the fuel system. A2 offers bigger injectors, and fuel pump with the turbo kit, and if you are 03+, you get a Boost Gauge instead of a FPR since 03+ lancers dont have the return fuel system. Now if you get the return fuel system, you get a bored fuel rail, FPR, and other items to convert your returnless fuel system. The SAFC is a piggyback but RRM piggyback is said to be the best from alot of people. But price sometimes beats quality for me but the Apexi Safc2 is good from what I read and research. If you want all the readings like EGT, boost, A/F, get the wideband RRM offers with the EGT and Boost sensors but you know if you get their wideband with all the sensors you will be spending 500+, someone correct me if I'm wrong. What I'm gonna do is get the A2 kit, they provide a boost gauge and I will get the SAFC2 and wideband from that site I post in my first post. Of course that's what I'm doing and I'm not suggesting you do that same.

For the lancer, for each psi you get 13hp so 13 times 10 will get you 130 added to your pitful 120hp so that's like 250hp total as long as you tune it right ofcourse.

 

I'm waiting to see someone run on the A2 kit. Last I heard, 9 or 10 psi was the recipe for dead pistons.

 

Mirages can hold 12psi all day long, so I'd seriously hope that lancers could too. Anyway, all of the above information seems about right. If you have any specific questions that you would like answered to avoid clogging evom, simply PM either Prench or myself, and we'll be happy to answer anything A2-related.

 

you guys have to remember, how much boost a turbo is running doesn't mean anything. it's the flow of the turbo. a little T25 can probably run to 15psi before blowing the engine while a T28/16G may only run from 7-11psi. it's about flow.

you're also more inclined to run a tad more boost with injectors, pump, and afc as lowering your airflow corrections table to compensate for the larger injectors will inadvertently lower your ignition timing tables as well. this doesn't happen with an fmu.

also, the longer stroke and tiny rods limits us compared to a mirage. the price we pay for the extra torque.

 

Well if people say the mirage and lancer have the same engine why do the mirages seem to perform better? is this because they are 1.8 and we just bore that out to 2.0 and make the block weaker?

 

its the 04+ that have the returnless fuel system....

 

Thats what i thought since the 02-03 is different than the 04-06

 

Mirages perform (handle more boost) better because they have a thicker block, and a shorter stroke, with a 9.5:1 CR.

 

Doesnt RRM stage2 kit up the psi to 9-10? If so, I dont remember them suggesting gutting the internals.

 

i'm sure they'll suggest it, but no, none of their kits require internal upgrades.

 

So if you changed out pistons and rods with a turbo would it be better to keep the same compression up get high comp pistons?

 

u want lower compression to run more boost....
