Difference b'n R Spec and V Spec Greddy FMIC Kit?

Sometime ago It was posted. However, searching has yielded me zero. Whats the difference b'n them?

Also, anyone have any regards to their personal experiences with either Kit? Good or bad, anything relating to first Impressions, Install and most Importantly - effieciency? I'm ready to buy the kit and would like confirmation from you guys.

i believe it's a difference in the way the fins are positioned/angled. could be wrong though.

There are acctually 3 kits Vspl-24 RSPL24 and the rspl32. The V-SPL has a 2 row core and comes with piping for the stock turbo. The R-SPL 24 comes with a better flowing 2 row core and piping for the Greddy turbo kit. The RSPL 32 has a 3row core and piping for the Greddy turbo kit. These are all new style kits, the old greddy isn't sold by them anymore.

The size of the cores.

R-Spec == For huge amounts of horsies.

V-Spec == For smaller amounts of horsies (<400hp)

I actually believe there are only 2 cores. The 2 row and 3 row. The 2 rows have one piping design for the stock turbo, and one for a greddy turbo upgrade. You could be right about the different cores, but I didn't think so.

I thought one had better efficiency but more pressure drop, and the other had less pressure drop but lower efficiency. I remember reading that somewhere, but not sure if it's accurate. Why not just call GReddy and find out.

The difference between the V-Spec and the R-Spec IC's is the inner fin design.&nbsp I believe there's a link to GReddy for more info?&nbsp The V-Spec kit was designed for stock turbos and less pressure drop.&nbsp The R-Spec IC has better internal fin design for better heat transfer over the V-Spec IC.&nbsp Otherwise they are basically identical on the outside.

There is a 3row R-SPEC core, Richard has it on his S4, its the same core as the Supra TT greddy kit i.e. huge. It has been argued that the V-spl24 and R-spl 24 use the same core and the difference is just the piping kit, but I am not sure. There are definatly 3 models of the new Greddy intercooler however.

No, there is a difference between the R-Spec and the V-Spec internal fin construction.&nbsp Whoever said otherwise is is plain wrong.&nbsp The V-Spec IC's were designed for those wanting the "big FMIC look up front" with a cheaper price tag.&nbsp Thus, the V-Spec IC was designed.

Yes, the smaller 24 row IC's are cheaper than the big 32 row R-Spec IC.

I have the VSPL.

Is this the V-spec model.

Thing is huge. Should be good for my TO4B.

Silverotor did you not see my car once. It have the greddy Vspl. Took some work but it is install and look clean. I did not notice any noticable lag either with the stock turbo.

As It stands, I plan on getting the V-Spec Greddy FMIC Kit. Primary reason Is to use my s5 Turbo. Knowing me, I will upgrade to a new Turbo eventually but for know, I need to complete the NA>TII conversion so the V-Spec Is the perfect canidate.

As for the piping b'n the V-Spec and R-Spec Kit- are the Internal diameters the same?
I think pics are due. I'd like to see your FM setup again IAN.

As for the V-SPL, does the piping for the stock Turbo have a 2.5" out of the Intercooler and a 2.25 from the Turbo to the Intercooler?

Let's here some Impressions.

I felt a NICE gain with my V-SPL at only 8 - 9psi on the stock turbo.
