View Full Version : Would this do any damage?

09-06-2010, 04:07 AM
I'm going to do a (correct me if I'm wrong Murg) V radiator on my swap. I'll put the bottom on the core support where the condenser sits, and the top where it normally connects.

The problem I have is the opening is 26"....and the Autopwr radiator is 27". I was thinking of cutting out 1/2" gaps on each side where I can angle the radiator through the support. Would that cause me any issues in the long run?

I've never seen it on a celica, or any transverse engine drive car for that matter. Is it possible? Yes. Is it reliable? You have to think about how close that exhaust manifold will be to the heat exchanger.

It's going to give me more room than I have if I were to install it normally. If I leave the radiator in stock position, i have less than 1" between the radiator and the cat. NO room for any cooling fans at all.

If I were to install the radiator at an angle, I have clearance for the fans and my intercooler pipes have room as well.

It will work just fine as long as it doesn't sit at too much of an angle. The farther the bottom is offset from the top will affect the amount of coolant that can fill the top of the radiator tank. It could trap air and keep coolant from flowing properly.

How many inches are you going to offset the bottom from the top.

09-06-2010, 03:25 PM
I'm only looking to offset like no more than 2". Instead of the stock mounting location, it's going where the condenser sits.

The other option I have is mounting the radiator where the condenser sits, and cutting a hole on the top for the radiator cap and then welding a plate back on for radiator cap access/etc.

Before I even bought my miata, I was planning on buying this kit.

Linking 'cause it might give you a better idea on how to make it flow.

I'm not looking at going that extreme. I'm looking something more like this.


On the left is the top view. The red is the normal radiator mount on the bottom, and the blue is where the condenser sits. On the right is what I'm planning to do. The radiator bottom will sit in the area where the condenser sits normally, and the top where it normally connects. It's not as extreme of an angle. I'd just need to figure out the lower radiator hose off the radiator though as I'm sure it'll hit the core support.

09-06-2010, 05:59 PM
2 inches will be fine.

09-06-2010, 07:28 PM
Well it worked as I expected, but the radiator sits just a :hair: too high now so the hood doesn't close all the way. Any suggestions how to lower it without damaging the support excessively? I'm thinking I can drop the bottom of the radiator to just behind the intercooler, but I'll have to do something for the lower radiator hose and then re-fab the support bar I just made to connect the core support up to behind the hood latch.

So did you remove your A/C? Just trying to picture it. Did you cut the sides to allow it to fit through?

I think the key thing is now finding a way to seal the sides so that air doesn't just escape around instead of going through.

But an interesting idea. Got pics?

Also, I'd just try to lower it down from the bottom mounts to get hood clearance.

Yes, I have pictures.

I removed the AC components. I only rolled back the sides 1/2" on each side so the radiator slides through nicely without leaving massive gaps.

I can't lower it from the lower mounts, as it's resting on the core support (where the condenser usually sits). If I install it where it is supposed to install, I don't have any room for the intercooler pipe coming off the clocked turbo.

I'm wondering if there's another radiator I can use (honda/nissan/etc) that I can put in there that's the same width/depth, but an inch or two shorter height.

09-09-2010, 01:58 PM
I found this one here.


I'm thinking if I install it on the drivers side and then block off the other side with a plate or something so air goes though the radiator that may work.

09-09-2010, 02:36 PM
Should be fine. It's a 2 row radiator so it will be comparable to your single row. Don't block off the other side. It won't change the amount of air that flows through the radiator at all. Leave it open to keep engine bay temps down and help the radiator shed heat.

I'm gonna check out the insulation hopefully when I get home like we talked about last night too.

09-09-2010, 06:30 PM
you can drill the welds off the lower mounts and lower them. that's what we did on my car.

09-09-2010, 06:45 PM
Hm, I'd probably try to get a full sizer if you can...

09-09-2010, 07:56 PM
Can you tilt the top back any more under the hood? How much clearance do you need? If you can rock the top back another inch, would that be enough to clear?

It would, but then I need to do something to let the lower radiator hose clear the support. Pics coming tonight (I promise lol).

So here's the pictures.

From the front, hood closed.


The hood is off this much when it is closed all the way.


This is how much I need to accomadate for in height.


Notice that's the same as from where it normally sits to where it's currently resting.


As it is right now, I have about 3" of clearance from the radiator to the engine components.


Now if I do as Murg suggested and tilt it back further, the hood will latch all the way without hitting the radiator (or it feels like it doesn't). The problem with that though, is it's VERY freaking close to the exhaust components, and also is barely resting on the wastegate bracket I made.



I'm thinking of keeping it the way it is in those pictures. I'm just concerned now about fitting cooling fans on the back.

09-10-2010, 06:54 PM
Interesting. Yeah, short of a shorter rad, that will be tricky. What I think you need is a 2"-2.5" 45 degree hose coupler right off the turbo, which would allow you to take that bend a lot tighter and be further from the rad.

09-10-2010, 06:55 PM
I'm looking at pic #5 and that looks like to much of an offset to me. It looks to be about a 5 inch offset.

If you are going to keep the turbo clocked then you should consider a different radiator. The way you have it setup now is likely to give you problems. You can't fit any fans there and the radiator is just too close to the manifold if you tilt it forword. It will make oil changes a pita. Not to mention if you have to pull the turbo or manifold off for some reason.

That's just my opinion though.

09-10-2010, 08:09 PM
So it looks like my options are to find a shorter radiator, or unclock the turbo.

09-10-2010, 08:40 PM
Or do what I said and get a different coupler. $20 fix.

So is that 45* pointing back towards the engine? I just can't seem to picture how it will work. Guess I'll run by a CSK/Autocrap and grab a 45 coupler to test out.

09-10-2010, 10:53 PM
Sorta back towards the engine, and sorta angled to the side. You just play and twist it until it fits nice. Allows a nice shot right between the rad, motor mount, and downpipe. Coming off of that is a 45 degree bent pipe, then u-bending to the IC.

09-10-2010, 10:56 PM
Yeah a 45* couple would run it pretty much straight down, once you turn it right, meaning it doesn't take up more real-estate.

It looks to me like you have some tabs and brackets still on the radiator and the radiator support on the front the of the car.

If you were to spend a couple of hours up there with a cut off wheel and a then finish it up with a dremel, I think you could cut your radiator support out a bit, leave some thin strips of metal, bend them to make new lower brackets, drop the radiator another inch or two, and have it sitting at a much less extreme angle. You might wind up dropping it a few inches below the top of the intercooler, but I don't think it would be that bad.

Once you finish that, put a single pusher fan on one half, use the 45* coupler off the turbo and then finish it all up and rivet some flashing around there to consolidate the airflow through the radiator, you might be good. You might even be able to get away with a single small puller and no pusher if you can move the radiator forward and inch (some cutting above and below) and use the 45* coupler.

Not being mean, just giving some helpful criticism, but if you clean that up and cut a little, you will gain a lot of room, that looks kinda like it has just been shoved in there. I am sure it is just a test fit and all, but if you cut, it will fit.

09-11-2010, 12:16 AM
Totally understood guys. Thanks (really, thanks).

Murg, that was just 'thrown' in there for test fit. I see what you're saying as well after I looked over the pictures. I'm just more concerned about chopping into that core support (where it's resting on). I'll cut off those radiator mounts (on the back side by the engine) this weekend and see what I can come up with. Gotta pick up a cut-off tool too (mine's fuxored lol).

09-15-2010, 07:19 AM
imho if you solve the piping job on your clocked turbo, you wouldn't have to really move the radiator..

i was actually thinking of clocking my turbo too, and the ones i've seen here didn't have much of a problem with fitment.. i just think that finding the right angle coupler and elbows should do the trick.. :D
