For those running the GReddy two-row FMIC with "larger" singles, ie. GT3540/T78/88, T66, etc...Do you feel it's "hefty" enough to handle the airflow these turbos produce at 15+psi?

The reason I ask is that I was supposed to receive a three row on Friday but the wrong part number was submitted and I received a two-row Type 24R with aluminum piping. The thickness of this core isn't much greater than my Fluidyne radiator and I'm worried it won't do it's job as well as the very large SMIC it's replacing (CWR).

I'd like to do it right the first time so thoughts appreciated. Kyle aren't you running a two row?
Michel

 

wow!!!!! that sux man i hope you get it workd out.... who could make such a mistake.

 

LOL, Rich, hey, I know where you work man :-)

 

Oh and that would be me who made the mistake with the part number even though I specified the 32R THREE ROW damn it...who was it that didn't double check the part numbers? :-)
Michel

 

rx7tt95: you are correct, I am still running the Greddy 2 FMIC. I think the 2 row will be fine up to about 20psi?!? I donno, just guessing. It seems to be doing fine with the boost I've run up to this point (17psi).

Next spring when I start running 20psi+ I'll likely opt to upgrade to a 3row (cheaper than a new engine).

So you don't see your IAT's go up dramatically when on the boost say while tuning? Things hold fairly constant?
Michel

 

Ihor and 40oZ also run the two row with GT3540's.

 

for 3540 is should be enough but i am running greddy 300mm x 600mm 2 core with my 51r and it is not enough. watching air temp on dyno run it was slowly rising. if you are runing the right size core your temp should stay consistant are slowly drop. i am talking about a 5deg rise or drop

 

i have the 3row with my T78..... runs awesome

 

I hear that the 3 row is the way to go if you ever want a FMIC. I also heard that a 3 row sits right in front of the radiator, whereas the two row has some space in between.

Too bad they don't have the 4 row for FD's here...they have it in Japan

 

I have the GT3540 kit and went with the greddy 2 row vs the 3 row. But I wont be running more than 16 psi. But the main reasons I went with the 2 row was Dave at KDR recomended it if I wanted to keep my A/C. The 3 row is so thick you need to remove some A/C components. Also he mentioned about 2-3 psi more pressure drop vs the 2 row. Cooling is not a factor as I also have a fluidyne radiator thats now in the upright position and isnt right behind the intercooler. I do not have any other info at this time as far as temps etc.

 

But aren't the larger turbos supposed to be more efficient and therefore produce less heat at a given boost level ? , if temps. are climbing , maybe something else is wrong ?.

 

2-3PSI pressure drop alone is pretty high. 2-3PSI over whatever the pressure drop of the 2 row seems ridiculous!

 

i'm running a 3 row with a gt3540...all ac components intact, just had to be moved around.

 

I have a hard time believing the new 32R core is 2-3psi more restrictive than the 2 row. I'm willing to bet that the 3 row, at a given boost level doesn't have 3psi of pressure drop across the core. Just an educated guess as I'm sure GReddy, HKS, etc...all use quality cores. At 13psi with the stock turbos, my CWR stock mount didn't had less than one psi of pressure loss as measured by a GReddy dual pressure gauge. As turbine size goes upward, so does CFM of flow and perhaps with the larger turbos at higher boost levels, there may be some issues. But I'd think that the three row would flow more than the two row. FYI, they used to make what they called a 19R core, three row, but shorter than the current IC's. Seems like THAT core would actually have less pressure drop (more, shorter straws so to speak) but they chose to discontinue it.

Anyway...I've decided to try and sell the two row and purchase the three row. If you're in the market and looking to acquire a two-row, here's your chance. Brand new in box at 25% off list.

This is the GReddy pn.#12040057 RX7 (FD) 1993-96 (2) Type 24R FM / GTK / GP, list price $1,580.00 which features the R-spec core, fully polished IC with polished ALUMINUM piping for a single turbo setup. It's brand new and still in the box, never been installed condition. I "attempted" to purchase a three row and gave the wrong part number and received this one instead. GReddy won't take it back so I'm forced to sell it at my loss. The price is $1180 FIRM not including shipping (which is 25% off list btw..). I can have it to you via next day air if necessary. If Paypal/Credit card is used, then buyer incurrs the additional fees associated with that. If you use Paypal electronic transfer of funds, there's a $5.00 fee. I'll also do COD, secured funds, through Fed Ex only. UPS is too slow :-) I need to sell this quickly as I have someone waiting on my CWR IC. Please e-mail me privately at rx7tt95@aol.com. Thanks!

 

as long as you understand that rx7store sells it for like 950.

I'm running the 2 row. My intake temps are always within 15 degrees of ambient. The main reason I went with this vs the 3 row is because I road race and didn't want to preheat the air to the radiator too much. I've ran 16 psi and had no increase in intake temps. If they start creeping up then I am going to go with a custom intercooler from RPM Performance Center which is even bigger than the 3 row, and desinged to fit with the gt 35/40.

 

Luigi, The RX7 Store DOES NOT sell the same intercooler for $950. GReddy offers several different IC's and the $950 unit is a V-spec core with non-polished piping (I believe it's coated mild steel actually). Look at the part number for the $950 unit. It's different from the one I'm selling the RX7 store is selling the SAME IC for $1250. So...I'm selling for less. Double check your facts Luigi before posting something like this.

So the 2 row for single turbo has the r-spec core?

 

Ok, if you look at the GReddy web site, they'll list several combinations for the V-spec and the R-spec core. The two row with the single turbo piping has the R spec core. The V spec core cannot be had with the single turbo piping and I wouldn't run a single turbo with the V-spec core because it apparently doesn't cool enough above 15psi.

2 Row core choices:
Vspec core to be used with stock turbos $1180 list
Vspec with twin turbos, for use w/Greddy piping kit ($1180 list)
Rspec core with single turbo mild steel piping ($1380 list)
Rspec core with single turbo with aluminum piping ($1580 list), this is the one I'm selling.

3 Row choice:
Rspec core with single turbo piping only $1780 list
They also list a 19R three row core which has been around for some time. I was told by a GReddy rep they don't offer that IC any longer.
Michel

It's actually pretty damn confusing with all their abbreviations and core designations, LOL.

 

So rx7tt95, does this mean your going to sell it to me for $950

I still need an IC, hook a guy up.

E-Mail me jeffshoots@hotmail.com

Shipping to zip 96003

Later, Jeff

 

Uh no. :-) I actually decided to just install it. You cannot buy this IC anywhere for the price I was selling it at but too late, LOL. I'll shoot you an e-mail here. :-) The $950 IC is a totally different IC unit, IMHO, not as good, depending on your setup.

i'm running a tiny greddy smic with my T04S and it has no problem handling 18 psi. Everyone is shocked to see me run over 15 psi with it. I would guess 2-row is sufficient for 22 psi.
