1G radiator in a 2G? [merged 5/08]

[MJcanada]

Not 100% but I'm pretty sure the brackets/mounts are in diff places. You can do it, but what's the gain? I don't see it being worth it

[97gst_spyder]

Yes it will fit once you move the lower pegs on the bottom to fit the 2g location.

Its a better design due to the upper hose being moved to teh passenger side farther away from the mani and turbo. Less heat, better cooling, longer hose life.

[abaum565]

The top mounts are the same, but the bottoms are different. You will have to modify the bottom mounting locations in order to make it work. You will also need a 1g upper radiator hose.

Many people do this mod to make room for large turbos and waste gates, as the 1g upper hose location allows for more room than the 2g hose location.

### I got a performance aluminum radiator for crazy cheap, but its for my 1g. and it sounds like there are some upsides to it! im gonna be running a custom t3 TS mani with my HX35 with dual EWGs dumped so ill need all the room I can get. Thanks guys

[bryanwheat]

I've got a 1g radiator in a 2g car. The bottom pins lined up good. The uppers are located about half an inch in towards the center. The mounts will work fine, they will just be a little at an angle. You will also have to trim the upper radiator hose to make it fit.

I don't have much knowledge on the 1gs yet but it looks like their are some benes to the rad swap. I am currently figuring out how to swap in my evo 8 turbo in my 2g gst. I am picturing it being done but with a lil custom work. Would be a nice upgrade over the mini t25 Idk still a few things to figure but it seems somewhat possible at the moment to be set up to use without switching over to the driver side. Which wouldnt be impossible since i have the IM to follow but not looking to go with that much custom fab work lol.

You will need to cut and relocate the lower mounting tabs for the radiator. You can fit a multitude of radiators in these cars, as long as you can fabricate or have someone fabricate the proper mounting tabs. I put a civic half radiator in my car, I had someone TIG some new mounting tabs where I needed them. If you are going to run a proper tubular manifold, then it is definitely a good idea to use a 1g radiator. This will relocate your upper radiator hose further from the manifold to keep it from melting. A 1g upper radiator hose should work fine.

Like this?

[boostedjay32]

I somehow have one. I think I just bent the brakets down to hold the raidiator down. And its only one pin in the bottom brackets. Cools normal with one fan and a vrsf fmic in california weather.

Jay-Wel - I merged your thread with the existing one on this topic. See post #28.

You got that backwards. The uppers are close enough, but the lowers will need to be moved.

Hi there,
So Im dropping a 1g fluidyne Rad in my 2g to allow the upper rad hose to clear the exhaust manifold. I was wounding if anyone has photos of this process, and what you used for a new aluminum rod to weld on for the mounts?
Thanks!

Dexterholland04 is putting a 1g Fluidyne radiator in his 2g car tonite. We can take pics and document the process if you'd like.

[bryanwheat]

I didn't have to change any of the mounts. The bottom ones fit right in the holes. The top ones were about a quarter inch different. The rubber in the mount can stretch and take up for the extra distance.

[Funfettie]

let me go double check, but im pretty sure mine are way off? yea that would be sweet if you could document the process tonight! would greatly help. I just cant seem ti find and aluminum rod to replace the mounts with

EDIT: yea the bottom mounts are 16 1/2" apart on the car, and the rad mounts are 15 1/2" apart. and the upper mounts are 3/4" closer that the car mounts

[dexterholland04]

Honestly, I just placed the radiator on the mounting ears (not through the holes) and bolted it in with the upper mounts. I had to slightly angle the passenger-side upper radiator mount because of the location of its corrisponding mounting peg. I cranked down on the bolts fairly good and that sucker isn't going anywhere! You could also use a Dremmel and enlarge the holes about 1/2" (making them more of an egg-like shape) or so on both sides to get the radiator to fit that way. Just some ideas...

[MJcanada]

can i ask why ppl are always trying to put a 1g radiator in a 2g? don't they sell all aluminum radiators for spyders? Their radiators are the same as a 1g and you don't have to ask how do I make it work because its already a 2g radiator. Look
Actually if I remember the look of a 1g rad the spyder rad upper hose is over farther, not sure in that though.

[Funfettie]

Well, the 1g radiator's upper hose is pushed more towards the passenger side of the car so its further away from the manifold. This helps by keeping the rad hose cooler, which cools the engine better. another reason is to allow the upper rad hose to clear after market manifolds. Thats why im doing it. I managed to sneak an evo X EF4 split port turbo in my dsm, but clearly the manifold is in the way.

Not sure about the first question, but for the second part yes there are 2g radiators for the spyder. However in that pic you posted for the spyder gs the upper intake hose has to be slightly modified as such:

[Funfettie]

Yepp, it was pretty easy to install. just cut half the lower mounts off, and stretched the upper mounts a little and it fit great

sorry i should have been more clear. my question was why don't ppl just buy a all aluminum spyder radiator for their 4g63? the radiator hose wouldn't be in the way of the intake if you used the radiator with a 4g63. which is what will most likely be what ends up in that spyder lol

[Funfettie]

Im guessing its because 1G radiators are more available. I actually havnt seen a spyder radiator for sale, but i guess I havnt looked. haha

Where did you get that thermostat housing? Nevermind, its from a Spyder.

I am not going to read through this entire thread, but I have a 1G radiator in my 2G. All I did was cut those rubber things off the bottom of the radiator. Dropped right in, used the 2G lower hose and 1G upper hose.

More room, and the upper hose is further away from the heat.

Free mod.

Ok ill bring it to you then. What I was saying was why not use a 2g spyder radiator instead of a 1g? I know the reason for a 1g rad ina 2g. The spyder rad upper, hose I believe is,a lil farther over than the 1g rad. Itd be just as cheap mod as,doing a,1g rad and it drops in. no cutting your rubbers or anything.

[99gst_racer]

Is there such thing as a Spyder-specific radiator? (I've never looked for one) And if there is, is it just as affordable and plentiful as the 1G aluminum radiators? If the answer to either of these is 'no', then it's just best to do the simple modification to the 1G radiator.

Yes there is. The spyder has the top radiator house all the way to far passenger side of the radiator. Its over father than the 1g rad.

Is it plentiful? Stock maybe I'm sure not as many private owned all aluminum radiators out there spyder specific. I'm sure you can get then though. Stock spyder radiator new is 75$. Used it would probably be cheaper since its not as wanted (yet anyways) as the 1g. Unless your buying from someone who its just,a rad to them. Then itd be the same price as a 1g. Ill see if I can dig up some all aluminum ones.

Go back a few and look at the pic I posted from the spyder I'm buying

[99gst_racer]

Sorry, I meant to say Spyder-specific aftermarket aluminum radiator - for the people that need to be able to weld to the radiator.

The stock one definitely seems to be a viable option for moving the upper hose though.

[MJcanada]

Doesn't seem to be a specific aluminum one. But when searching for it I stumbled over a, site that makes custom radiators. https://wizardcooling.com/?gclid=CLr...FaNeTAodTQSKvg

So for those making high hp builds instead of buying and welding to a radiator you can just get all dimensions and attachments you want, tell them , and get a custom rad built exactly how you want.

[MJcanada]

But mishimoto sells 1g style radiators for 2gs anyway so I dont see why you would buy a 1g rad aluminum or not unless its was just a good deal

Cutting rubbers is the fun part!

So, maybe the Spyder radiator has an upper hose that's EVEN FURTHER over on the passenger side (as if you even need more room than what the 1G radiator offers)? There will still most likely be some kind of modification needed.

The hoses are different being that the thermostat housing is different.

Just get the 1G radiator and cut the rubbers! Cheap, more available, and from a 1G<3
