Greddy Intercoolers

[SlowWhite]

I ran a Greddy Large 24Row FMIC with a HRC S20G turbo

Ran it at 20psi on 92 oct daily for 3 years during the 4th summer I played with 22-25psi on 92 oct daily. using the Standard couplers with "0" problems of Pipes blowing off, when I actually pressed the pipes together correctly. If I did a slack job they'd blow off.

My car put down 321whp Maxed out on pump. I have over 150 pulls on the dyno with this set up through out those 4 years

My setup up:
HRC S20G complete kit
HRC I/C piping
Greddy 24Row FMIC
Blitz BOV
HKS 264/272 cams
BPR7ES Spark Plugs
Magnacore 8.5mm Wires
Walboro 255 Fuel Pump
Used 550's, 660's, and 850's Inj (changed up twice during the 4th summer)
SAFC
ARP's
Clutch Masters Stg 3 Clutch
Ported 2G Exhaust manifold
MBC
EGT on the #1 runner

When I was at Tuned for Max HP on pump gas. My EGT's were at 1300 during Cruise, and at 1575 at WOT.

When I first started Tuning - I was told you have to tune so that your EGT's Gradually go up as you go through the gears.

Wel I started at 1000 and by the end of a WOT run I was at 1375. - I took that tune to the dyno and put down a wooping 255whp 20psi on 92 oct.


As for the Greddy FMIC - I changed it up to the SKYLINE GTR FMIC because it flows better. and use's Shorter/Larger Piping.

And since I was planning on running a Much larger turbo then the 20G I needed a better FMIC.

But I will say this - Jeremy suprised me when he put down 470whp with an FP Green and Greddy 24 Row FMIC at elite on C-16. But I think he had upgraded to larger I/C piping?

Most most people will say a greddy 24 Row is good up to a 20G Sized turbo anything larger and you'll need to upgrade.

I'll say this. - I beat the living hell out my My GS-T every single day I drove it. (why modify if you don't plan to use it)

Personally I think the GTR is an all around Better FMIC. Contstruction, Design, Flow, etc. It didn't change HP much for a turbo the size of a 20G but for the larger turbo I'm going to be running I have no doubt it will be a huge difference.
