Time to choose a radiator and I need your help!

[DSM_Newblet]

I have made up my mind I'm am ordering a radiator tonight! My HP goal is 350-400 max hp. I'm in 120 degree weather. I am going to be using after maket fans as well with shrouds. What radiator would you recommend?

 

[snowborder714]

This unit is really nice. Shroud seals off really well to radiator and the fans flow very well.

(Note: I bought the universal model they had and just had to hack it up a bit to fit around the in/out on the radiator, as well as fab up some small mounting brackets.)

I'm using a Mizu with 2 12" China fans and I'm suffering pretty damn bad!
I'm seeing 200*+ at 70ish* weather just crusing. I'll probably have to look into that Flex-a-Lite solution.

I have the same ones hate them.

same radiator, fans or both?

This is sick. On the 2gs, there is a cooler at that location. Not sure what it's for but aren't the 1gs set up the same way? Do you have to remove this?

There is an oil cooler on the 1Ga (90-91) and a loop for the power steering, and the AC condenser goes there too. I extended the lines for the oil cooler and put it on the drivers side vent, got rid of power steering (although you can just move the loop) and never had AC. You can keep the AC with a FMIC and a Scirocco rad.

The rad is installed in that picture. That was more to show how the a/w fits in there. With a 2G manifold and B16g the closest the turbo gets to the radiator is about 7" Doesn't seem like a lot, but measure it in stock format. I wouldn't have it any other way.

Mizu fan shroud. Its on the stock radiator

Thinking about changing the fans and keeping the shroud. Now so I dont continue to change my set up. Would the Spal fan be a better choice over the Flex-a-lite ones.

 

[DSM_Newblet]

I got the radiator installed but it is still overheating. Even hotter then before.

Check radiator hoses, thermostat, radiator cap, and fluid level. Make sure your running 50/50 mix maybe try a bottle of water wetter. Are you using the stock fan or slim fans are the fan(s) turning on?

 

[LandoAWD]

Fan wired backwards? Tuft it.

 

[DSM_Newblet]

I replaced everything in the cooling system literally and use 70water/ 30coolant with water wetter. Slim fans with shroud and cxracing radiator i just replaced. Fans are fine. It did help cool it a little when I turned off my AC but at idle it still climbs, but it's like it won't go past a certain temp.

 

[Smeed78]

I run the Mishimoto radiator and Mishimoto fan shroud. The combo does its job really well. The temp does rise a little when the A/C is on but it doesn't overheat

 

[DSMReviver]

I got mine form ebay and works perfect. Looks exactly like the OEM and performs even better and it also has an auto trans cooler in place. I don't know what brand it is because i bought it long time ago. But, just because its ebay don't drop it off your list.

Mishimoto produces cheap parts, and their quality control needs work too. Their caps are atrocious, and sometimes flanges are warped.

Personally I would put up the extra few bucks for a reputable brand name.

that's odd since they are one of the few companies that have a lifetime warranty on their product even if its in an accident. I have used a lot of their products and never seen any of these issues that you talk of quality control wise. do you have any personal experience to back up this statement?

see personally I have had the cx unit and the godspeed unit start to leak from the welds on the end tanks and become scrap within a year on other cars I own so I will not use or recommend those parts.

Unfortunately on a 18-22 year old 1g the fact that newer companies even take the time to make parts for it makes me happy and I have no personal experiences with any mshimoto product failing other than a fan when on my 3000gt I cooked the motor with the front turbo.

 

[my dreamt dsm]

Funny story. I see many high power dsm running stock radiators. And I'm sure they will hold too.
I bought the cx racing rad= mishimoto radiator thinking I'll see significant gains in temp drop, but evoscan say's heck nooooo.
It fits okay but it might also needs after market slim fans depending on turbo. Great, more money to spend.
If I could do it all over again. I would just stick to stock. I remember paul/ 99gstracer or some autocross dsmers saying that stock fans are better then any other fans they bought.
.02 cents.
Brian's gsx (illeclipse), fp3052 turbo, 11 second dsm... never had a radiator temp issues.

+1 to the stock radiator (and fans if you can fit them). Making more power doesn't necessarily equal more heat. Look at the guys making 1000hp+ with a Honda half radiator. Most aren't even cooling the block itself, just the head.

In my experience, 99.999% of overheating issues are from a poorly maintained cooling system or failing parts, not a cooling system that is inadequate for your power level. The majority of heat doesn't come from combustion anyhow, it comes from friction.

 

[guapking]

Ebay Aluminum radiator with fans and shroud for under $200 shipped. Works well and fits nice.

 

[DSM_Newblet]

I got the problem fixed. Turned out it was just a bad tune and was running lean.

 

[guapking]

Good to hear.

Thanks great info.

OP glad you got everything worked out.
