Aluminum Radiator

[TWOLOUDNPROUD]

I don't know witch ALUMINUM RADIATOR i want to use so i am going to let you guys decide for me with a poll.Here the two ALUMINUM RADIATOR should i go with the half size or full size here some pic's.By the way this is for the B20a Turbo project i want to make sure to keep it cool.

[Hauntd ca3]

Go for a two row full width rad.
At least that way as you do more mods to the engine it can keep up with it.
you wont over cool or anything silly, thats what thermostats are for.
and it'll look better than a faggy wee half width one

[BITESIZE]

With the turbo, I say half. Gives you more room to play with, plus the half radiator will be just as good as a full one. You're going to need the extra room for that huge turbo.

[Hauntd ca3]

but with horse power comes heat.
If you can cool it in a more stable way for longer periods of time, the motor will last longer.
A half rad would be luck to keep cool for 2/3 hard laps o a good circuit.
Unles you want to be a quarter mile pony that is.

[BITESIZE]

oh, is it thicker than the full size?

Hey Guys thee is a poll at the top of the page Vote.

it all depends. wickedaccord is runing a civic half size one on his 400whp turbo car. imo half if you need room....fullsize if you dont need room...make sure to get a good fan for it also

dude all of the super high hp civcs run half size rads. I'm sure you will be JUUUUST fine.

I am going to be snagging a half wide rad for my setup, and I am paranoid about it, but I am confidant that it will be ok. Consider how nice the 3 row radiators are compared to the shitty single row design.

[86AccordLxi]

I have a 3" Mishimotor rad in my 240...honestly, I wouldn't want anything smaller, but that's just me. Water temp gauge make me paranoid like whoa, though, so the more cooling the better. I need to get some ducting going, now.

[bobafett]

yeah if you have ROOM, you might as well run a larger radiator. Unfortunately I will be forced to run the civic one. But I am not worried about it.

[86AccordLxi]

Yeah, the s13 has TONS of room in the front of the engine bay, so I don't have any space constraints whatsoever.

I'd try to get the the biggest one that took up the least amount of room

Be careful with that fullsize. I bought an F&F Dynamics that looked just like it. The core thickness wound up being just smaller than stock, the fins have damn wide spacing, and there was no draincock or lower mounting pegs. Wound up getting a Fluidyne, there is no comparision.

[86AccordLxi]

I've had no probs with mine. Stock fitments, 3" thick core (vs. 1/2" stock), much better all the way around. It's a koyo knockoff but looks identical to the koyo. Haven't had temps over 190*.

Half size. I'll probably run one to free up some space in the engine bay once I feel like making it fit.

[88Accord-DX]

Can you pull enough air through that small radiator with a good fan? Probably going to be some variables on what needs to be happen. Got to think about if your running the shit out the engine with a turbo, is that going to keep things cool with a small one with a good fan. Just a few things that crossed my mind before shooting the cat. Have to take things into consideration.

[RobT5580]

If you dont have space issues definately run the full plus you can run two fans if need be. I have to wait to see how mine is going to fit but i would like to run a full one from a 90-93 Integra.

usually all those high horse civics only do the quarter mile thing.
Dont need much cooling capacity for that.
Top fuel rails dont have any cooling at all.
still think the xtra capacity is all good unless you like that quarter mile rubbish

Uh, no they don't. There's probably fifty 300+ horsepower D16 Civics running on HMT with a half-rad. You're pulling info out of your ass.

I'm going to be running a half-rad in my Prelude also, for the space.

[LX-incredible]

If you decide to go with that fullsize, I still have the F&F with the fans, never been installed...

EWWWWW pretty!! How much?

[LX-incredible]

I paid $375 shipped and it's never been used. How about $275 shipped.

This is my own person view guys, think what you will of it
I spin spanners for a livin and have spent the last 15 years fixing cars.
i dont claim to know everything, but i know a bit
I would dream of building an engine with a small rad with out running an electric water pump with computer control
300 horses creates alot of heat , specially if using a turbo.
have seen civic turbo at my local race track boil a wee rad in 5 or 6 laps
And alloy motors dont take well to overheating.
They all end up running the biggest rad they can fit in.
cheaper to use the big rad than rebuild a motor.
The only way i'd run a wee rad is to geta four core one and run the electronically controled electric water pump.

I don't need a radiator, but I have to say that the one in the picture posted by Bitesize is BEAUTIFUL.

I have a $99 special. It's the second replacement. I got it for free under warranty. Just FYI I recommend against any all-metal radiator that is not like the one pictured above. The underhood temperature ranges on our cars wreaks havoc with the solder joints on aluminum/copper/brass rads.
