New radiator time. Decisions...
So I have come to the point where I need a new radiator. I have a 89 RX7 T2 with a Turbonetics 60-1 that is oil and watercooled. With this extra load the radiator has a hard time keeping the car cool after a few hwy pulls. Granted i only see 98 degree Celcius on the PFC but it stays there until I come to a stop or slow down below the speed limit.
Which rads are you guys running reccomend.

I have a Godspeed. Cools good. I have a n/a though but It should cool turbo good too. It's basically a Chinese knock-off of the Koyo N-flow.

My problem is that while driving its fine. I hover between 89 and 91c in 100 degree weather. If any load is out on it I.e Full boost for a couple of gears it goes up to 95-98c. Never any higher. I think the bigger turbo is transferring more heat into the cooling system then the stock rad can handle. Yes, my turbo im using is water and oil cooled.

Are you efan or belt driven fan? Just curious.
Why are you worrying? In general, those temps are ok. The thermostat is barely open at the lower temps and is only *just* fully open at 95*C (203f). The OEM e-fan on the condenser also comes on at that temp, 97*c (207*f). If it continued to climb, I would worry.
Worry about something else.

Here is my writeup on the koyo n flow with stock shroud https://www.rx7club.com/2nd-generati...hroud-1063062/
With a little bit of fabrication, an aftermarket radiator would not be hard to modify and fabricate to fit the fc. Almost as easy as welding on an "L" bracket along both sides and drilling 4 holes. Electric fan of course. Running no heater would make things even easier for the radiator hoses

As low as possible. Big cooling nut here lol. I'm on a E fan with cog drive system. The Efan is a fully shrouded unit from a mercury villager I believe. You are right about the temps. It has creeped to 98 once but never any higher. It falls as soon as I slow down or idle.

Efan. I spoke with Chris at rotary performance who is a gd friend and he suggested the koyo n flow as well but he said it was a bolt in for the s5? http://koyoradracing.com/products/se...earch+Products

I like to keep them

Regarding radiators: I have a standard Koyo on my 90 very with a Lincoln Mark VIII fan set up for 2-speed. This is as good as it gets. 185* coolant on 100* days with full A/C running. On the TII I have a new CX Racing Dual pass rad. Very nice unit. This is the one I am building the shroud for. I cannot attest to the efficiency yet as I'm still in break in mode on a fresh rebuild. It comes with mounting brackets built in so you don't need those old radiator brackets.
