Intercoolers.. M-spec/V-spec/R-spec

[levelgx]

OK, I know alot of ppl compare the M-spec with the cheap Ebay intercoolers but I'm wondering whats the best bang for the buck. I'm lookin at the greddy V-spec hard but anyone have any better inputs on that. I'm new to 240's and to imports in general.. never really had to deal with intecoolers.

I purchased a used Greddy FMIC kit for our car and the guy didn't know which model it was. Can anyone tell by looking at this pic of the core?

Hey check out greddy's site I think they have the picture so you can compare cores.
Also when buying an intercooler you gotta pick one that will be effective.
Spec-m=stock boost
vspl=higher boost
rspl=racing application.

[paNX2K&SE-R]

I tried the Greddy site when I first bought it, no pics of what I need.

I know for sure its not the M-spec b/c ours is tube & fin. I was hoping someone with either the V or R would recognize my pic as looking the same as their core...

That's the v spec core. R core is tube and fin.

*edit - OMG that sounded so gay. PWNED by the "U" key LOL sorry!

[paNX2K&SE-R]

That's either the m or the v spec core. R core is tube and fun.

Sorry but your statement makes no sense.

[fakts13]

he means inside the tubes there are fins on the rcore. m and v spec have extruded tubes.

[paNX2K&SE-R]

The M is a cheap bar and plate like the ebay specials.

Anyway, someone pointed me towards JGY's site of all places for a decent pic of the cores:

http://www.jgycustoms.com/240sx/images/finpic.jpg

I'm thinking mine looks a lot more like the one in the top pic (the R core). What do you guys think?

[fakts13]

looks more like vspl. like I said before, rspl has fins inside the tubes as well as inbetween the tubes. the pic you posted shows a grooved extruded type of tube without fins inside

[skylindrftr]

m-spec: bar and plate
v-spec/v-spl: tube and fin
r-spec: tube and fin w/ a bigger overall core than v-spl is available with, same goes for amount of rows, www.rhdjapan.com has all 3 w/ sizes, specs etc... check it out

[usdm180sx]

v-spec/v-spl: tube and fin

That would be incorrect.

I checked RHDJapan's site and this is the picture of the rspl's inner core:

This is the picture of the vspl's inner core from their site. This is NOT tube and fin:

skylin: Thanks man thats exactly what I was looking for.

It appears I have the 'V' core which is fine by me considering I got the complete kit for $275.

usdm: The 'R' and the 'V' are tube and fin and the 'M' is bar and plate.

[KFLS14]

I have the M-spec sitting in my garage it looks identical from your pic last time I looked at it. I bought the piping used but brand new core/box/labled. I can take a pic but I say Mspec due to the price as well.

[SixSpeedSleuth]

M Spec is a great Intercooler for the money. I'm not sure who said it's for "Stock boost" but thats goofy. I run 18 PSI on mine daily, beat on it often, have made back to back to back dyno runs with little time in between on a 99 degree day with humidity over 100 percent with no heatsoak what so ever. FWIW, car dynoed at 425whp.

For the record, Vspec is NOT tub and fin. Look at the pic I posted.

Description of spec-v:

You are viewing a Brand New `Spec-V` (FMIC) Kit designed for a variety of different Nissan vehicles by the top notch tuning company, GReddy/TRUST.This kit is part of GReddy`s newest lineup of intercoolers with low pressure drop and best for quick response setups (increase boost on the OEM turbine up to the `sports turbine/internal actuator` type turbo setups).
The intercooler is a two-row unit with `tube-type` cooling passages and `micro-groove tube` cooling passages with complete aluminum piping for an extremely lightweight and effencient setup. In addition, the appearance of the core also been improved with a new CCP (Chemical Combination Polishing) for the most `bling` ever available from TRUST!!

In the description it says it has "tube type" cooling passages, which I believe, would make it a tube and fin type intercooler

It is fairly easy to tell tube fin and bar and plate apart from the exterior, as bar and plate have welds on the sides of the bars connecting to the end tanks.

= bar and plate

the v-spec, however doesnt have this, the tubes themselves are not welded to the end tanks:

[usdm180sx]

My understanding of the definition of tube and fin intercooler is that the core has fins inside and between the "tubes" of the core, like the core from the rspl. Outside pic of the rspl core:

Pic of inside the rspl core:

The vspl has fins on the outside between the tubes of the core, but has no fins inside the tubes:

`micro-groove tube` cooling passages are not fins, hence the vspl is not a true tube and fin fmic.

Hmm, not really sure about this one, maybe someone should email Greddy haha, maybe psuedo tube fin, but sure as hell not bar and plate...

Both of these are TUBE and FIN.

The VSPL is NOT. Done and done.

[skylindrftr]

so what exactly is it, are you sure it might not be just a lower quality version of the tube and fin?

[paNX2K&SE-R]

The 'V' is still tube and fin, its just not quite as good as the 'R' when it comes to the heat exchange design inside of the tubes.

Just get the R-SPL, then you don't have to worry about it.. LOL
