I have decided that I am going to use a DSM manifold and side-mount intercooler for my set up. I have heard several people say that the 2g exaust manifold will flow better than a 1g (exception of the EvoIII) ; but what about the stock intercoolers?

Anyone have experience with which one is better?

Thanks in advance. :hug3:

1g has a better turbo (14b), better BOV, better intercooler if you can find one in good shape. 2G has a better manifold
hmmmm.....
let's see
14B = 410cfm 6cm2 housing (known to crack)
16G = 520cfm 7cm2 housing

in my opinion, 14B is fine for a smaller engine such as a stock 1.8-2.0
16G is better suited for 2.4 and up
i have a big 16G and it spools up nicely
and will not max out at 15psi like the 14B

also i wouldn't recommend a side mount intercooler
headache to mount on our car and not really that much power gain as opposed to a FMIC which is even easier to mount, not that much more
and it looks sexy too haha

Agreed about the turbos. But after mounting my front mount, the side mount looks to be pretty easy if you are doing a custom setup. You don't even need to take the bumper off. Plus you won't run the risk of blocking air to the radiator. But not as sexy as at all.

I am pretty set on using the sidemount. I dont want to cut my bumper at all, and after reading about all the overheating problems front mount guys have, I think a sidemount will do just fine. In addition, I am only going to be running a 14b at 12psi at the VERY most. Plus, a sidemount could give me the "sleeper factor." :burnout:

i never had any issues with overheating...
maybe because my fmic isn't really blocking much of the radiator
if u get a massive one then yea u will have problems lol

intercooler is more important than u might think...
it's not just for more power
the cooler you keep the air the less chance you have of having detonation

so basically, with a side mount.. it means you'll have to run less boost
intercooler is pretty useless unless AIR is actually hitting it to cool it
stock 2G smic flows about 133 CFM
14B turbo is going to flow over 400 CFM
smaller ic means less boost and hotter temps
not good lol

Well jbasol is pushing well over 300whp and 15psi on his single sidemount, as well as many DSM guys making good power on them. Where are you getting the 133CFM figure?

I wonder if overheating has more to do with removing the stock fan shroud than anything else.

I'd say you are good with either a front or sidemount! I really dig your setup by the way Bruno.

wierd, I have never seen a 2g that came stock with a 16g?

no... you're right, it didn't
but, try to find a 2G that DOESN'T have a 16G lol
they almost all upgrade to it for a reason

How the hell is a 16g suited for 2.4 and up???
well
smaller turbos are more suitable for smaller displacement engines
more exhaust = quicker spool lol
at 3200rpm mine is at full boost

14B is great for twin turbo setups on a v6
16G would suck for that

anyway....
point being, in my opinion, the 16G is best turbo for the price,
for the 4G64 at least
14B might be less expensive, but you're stuck with something you'll HAVE to replace if u want more boost
and it's housing is known to crack

to me buying a turbo that has a low boost limit is like buying a boost gauge that only goes up to 12psi, kinda lame that u will have to replace it if u want more power/boost

like my friend has always told me
and i've learned the hard way wasting money
if you're going to do something, do it right

if yah arent boosting over 20psi, a small 16g will suit you fine. a " big" 16g flows the same cfm just wont run out of breath up top around 21+psi.

What is all this talk of "doing it right?"

In my mind, what "I" am after is what's "right" : a boosted car that I can drive everyday and will get decent gas milage. "Right" to me is a car that is just more fun to drive and will push me back in the seat a little when I push the go pedal, --and wont cause huge amounts of break-down-drama. :yesway:

doing it right to most people is building it to handle 400+whp. but as far as tuning is concerned, even for a little go power, dont skimp out, still throw it down with an EMS :)

A 2.4L engine should be able to spool just about any turbo at a reasonable RPM. If you want to do it once, do it right, get a PTE SCM5031 50-trim.
To each his own you can keep your 50 trim I'll take a gt35r on my next upgrade.

how about the 14B with a TD05H compressor instead of a TD04? i just bought a 14B with a TD05H compressor. i know the exhaust flow is still a 14B but what about intake air flow.
I've decided on this because i want the fast spool and hard pull but i don't want to much power that will kill my gas mileage and possibly break something in my motor, since cylinder pressure is lower then a 16G or t3t4 50trim
