R33 Gts25t

[Mattw_83]

Lads,

Had a search no info i could find..

Looking at Nengun and various others places for a possible replacement of my r34 SMIC on my r33.

Question is are ARC SMIC a good options as opposed to going front mount. This i wont be doing as i do not wish to cut holes etc required for installation and the aim is to keep to the car looking factory.

Anyone used these before? They are expensive by the looks of it but im not fussed if it is a decent performing product.

Ive decided to not go berserk with upgrades not sure how long ill have the car. Also searching for a decent Electronic Boost Controller to run around 10psi (rather not be replacing turbos either) and a tuning option without going powerfc etc. Around 200kW or so is the aim.

Current got 169.8 kw atw with a r34 smic, 3inch nismo exhaust and front split dump pipe, K&N Highflow Panel. Stock boost.

the arc side mount can handle around 230rwkw from memory...so 200rwkw goal the coller should be more than enough, plus you probably wont be hassled by cops

[phatlavish]

i've got an ARC sidemount in mine at the moment, theyre good coolers imo. slightly larger than the stock SMIC, and about twice as thick (the 100mm model)

running about 195rwkw with stock rb25 gear, ARC smic, 12psi with a turbotech bleed valve, 3" exhaust and remapped ECU

please check the temperature of the inlet and outlet after a few minutes of a trash run on your ARC SMIC

i would be interested in the in and out temps being a SMIC in the side mount location.

the main issue is airflow, an intercooler needs as much as possible to be of any useful purpose.

on a FMIC smack bang in the middle, the turbo side will be too hot to touch after a trash run

and the plenum side will be stone cold. this is how an intercooler should perform.

the issue here isnt power, as it will make power on a dyno no problems

the issue arises when you trash the pants off it on the street non-stop

and then its heatsoaked

[shaun123]

the JJR stealth cooler kit doesnt require holes to be cut AFAIK so that might be another option

[Ultimategtr]

Paul33 is bang on the money - imho - the side mount upgrades are a waste of time and money. No offence intended.

i looked into this but it seems u still gotta cut your reo bar which isnt roadworthy, and also a bit from your front bar which isnt a big deal at all but still. and also ive heard users say the return pipe scrapes curbs if your not careful.

i also thought of getting a good smic but i just cant see it cooling that well, specially on a hot day

[Beer Baron]

the side mounts actually get pretty good airflow as they are ducted. being sealed in a duct they get great flow through the core. the fmics are usually just in the front with lots of air gaps around them. they do work well, but so do the smic. the ARC is a great core. probably a bit overpriced new for what they are, but second hand they can be had for reasonable money.

Whats wrong with your R34 GTT SMIC?

They are good for over 200 kW's...

You've still got a bit of room you can push the power out with the R34 GTT SMIC...

[Jmaac]

i believe the blitz lm cooler is another option if you dont want to drill holes

[Basti]

ARC do make a return flow FMIC as well. i've got the same dilemma, while these return flows dont req cutting the chassis, they do screw areound with the reo bar. which is an issue

[paulr33]

again im not doubting power etc, im doubting the ability to reduce the intake temperature

even without an intercooler you could make 200rwkw on a single dyno run

it proves nothing, other than a single max power figure at a given RPM

on the street under repeated excessive load is where the difference will matter

Iam not too sure what your trying to say...

Are you trying to ask if an ARC SMIC intercooler will prove just as good if not better cooling then the R34 GTT SMIC..?

[Munkyb0y]

i think he's saying, dont waste your time with a side mount. theyre too small, get heatsoaked, and dont cool efficiently on the street.

i agree

the problem with using a thicker core smic to increase volume is that the thicker you go, the less efficient it is. its coz the air trying to cool the core is getting too hot by the time it passes that deep.

if the r34 smic isnt enough, go with a front mount. the benefit of the front mount is the larger front surface area. it can dissipate the heat much better. you will see how cool it remains after a good hard run compared to a smic that will be really fkn hot. that pretty much tells the whole story. ive had both, r34 smic with shroud, and fmic, and that's how it was for me.

but thats just my opinion

Yeah right!

I see your point, thanks!

True what you said as the FMIC.

So Mattw 83 wants to run 10 psi after he gets his Boost Controller, would he be pushing the limits of the R34 GTT SMIC and it will get very hot?

[Munkyb0y]

i'd say for 10psi, on the street, it wont be an issue.

[Mattw_83]

once the intercooler is heatseaked, this simply JUST reduces its output? No ill affects to components beyond that?

Ill be running 12psi (switchable) by the end of today new eboost being installed and dynoed this arvo ), hopefully she'll hold up...

[KiwiRS4T]

I was running a Trust smic (a little bigger than the R34) with a GCG turbo at around 200AWKW. Worked well including track days. people are running R34 smic with 200-210AWKW no problem. The ARC unit would be better but in my opinion you are fine with the R34 unit (if you didin't have the ducting make one up).

[johnsta2k]

what would an ideal intercooler choice if you're running around 280rwkw?

(sorry didnt mean to hi-jack the thread)

ideal choice for 280rkw = ARC front mount.
