I am looking to upgrade the intercooler for my FD. I know there will be some lag if I go with a Greddy 3 row with my stock twins. Eventually, I want to go single and if the lag isn't too noticeable was considering just buying the 3 row now, instead of buying a 2 row now and then a 3 row later. Has anyone tried running a 3 row with stock twins. Thanks in advance.

Yes I tried. Wasn't as much lag as I thought.

 

i wanted to do the same thing. cause i am planning one going single within a year, and i didnt want to but a 2 core and then end up spending a ton of money later on buying a 3 core.

 

Just wait until you get the single turbo and then buy the intercooler. I would buy all the parts at once. Just my 2 cents.

 

Some guys I know are running up to 20 lbs of boost on a 2row with a single turbo , depends on how big the turbo , and for street/ track duty ??

 

i just posted in the single turbo forum asking if the 2row was good enough for a single. From what i gather your good to a solid 400hp

 

Yeah, get the 3-row. The sequential twins might take longer to make big boost (to fill the larger volume of a 3-row). The 2-row is perfect for sequential twins for up to 15 psi boost.

 

You can never have a big intercooler . The three row is the best. If you are planning on going single, don't waist your time on a 2 row. Do what I did, buy all the single turbo pieces one by one and when you have it all just go single. If you feel a little "need for speed" just install the 3 row and wait for the other stuff to arrive. You may have a little lag now but when the big guy goes under the hood, there will be no lag or anyone next to you that can keep up. Unless its me .

 

Cool guys, thanks for the input!! I'm gonna go with the 3 row.

 

2 row is fine.

 

2row...3row which? If a stock FD makes 220rwhp stock on the tiny stock i/c with like 250cfm how can a 2row with 750cfm not be able to handle 400hp? Am i missing something here? Would you see a horsepower increase, or just an decrease in airflow thru the core before it hits the radiator?

 

Kyle Bacon used a GReddy 2-row FMIC with a GT35/40 single. At 17 psi and good Power FC tuning, Kyle's silver bullet made ~500 rwhp. No one is saying the GReddy 2-row Type 24 V-spec won't work.

The GReddy 3-row Type 32 V-spec will buy you better cooling efficiency and higher CFMs (cubic-feet-per-minute)--both lead lend to better rwhp production. IOW, rwhp production will not be limited by the size of the intercooler.

Generally, if you have twin sequential turbos, and plan for mid 300s to ~400+ reliable rwhp, the Type 24 V-spec (2 row) is the optimal choice. If you have a single turbo, and plan for mid 400s to ~500+ reliable rwhp, GReddy Type 32 V-spec (3-row) is your optimal choice for air charge cooling.

 

excuse my ignorance, but what is the difference in build between a 2 row and a 3 row?

 

Where did the CFM numbers come from? Unfortunately you need to know psi that the CFM was achieved at and pressure drop would be nice as well. CFM by itself is a meaningless number.

The 3-row has a deeper core, 4" as opposed to 3", me thinks.

 

boostn7 ran the 10.98 on stock twins with a 3row...boost drop/lag my ***

 

Kevin the information i'm referring to is as follows its shown as volume i was confused on volume/cfm. Its an older post on a site, some info you stated was listed further down on the page...

..........thickness, width, height and volume
stock i/c 2.5 11.5 4.5 129.375

old greddy fmic 4 16 10.5 672

 

...what he said, the difference in volume is nothing with that much air moving that fast. We're talking like a .01 sec difference here.

 

I am running into the same decision as well. Not sure whether or not Im gonna go single or not. I got two sets of stock twins so I think Im gonna get the bnr stage 3's but after that Im not sure if I wanna go ahead and get the a-spec gt40r or just stick to the twins. If I go with the twins it will be the 2 row if its single of course the 3 row. I have a dilemma.

 

So how much work to install the 3 row? Cutting? Removal of what? Can I use a small battery and keep it up front? Is there a serious issue with flow to the radiator?

 

if doing road course events, 3 row could raise coolant temps due to rad flow restriction. Blitz and Apexi fmic's allow some bypass, and may be better high hp fmic options for such use.
