Radiator Sizeing


Juiced

Recommended Posts

Ok, Now one of the final things i need to complete my buildup is a radiator. What Size/brand radiator are you guys running in your Hybrid z's to cool a high boost Motor. I'm assuming the V8 conversions would be enough considering they are adequate to cool an iorn V8. But i'm concerned because i'll still need room to route the Intercoller pipeing. DOes anyone have any ideas.

dude im for sure you can find oodles of information about radiators if you just search, we've got tons of info on that, but here's two recommendations i might say:

MSA 4 row radiator w/electric fan

arizona z aluminum rad w elec fan

 

the radiator is not the only cause of the z's cooling problems, this site should inform you....but remember, the search button is your friend....

i Did do a search under radiator and most threads are directed to the SBC and SBF guys. The problem i have being running the intercooler pipeing beside the radiator.

 

I've read that article before, but see i'll be running the SR20DET with an electric SPAL 16" Fan, and have a vented hood, and large front air dam.

 

I just want to know the dimensions and types of radiators most commonly associated with the swap...

the way i see it is....the stock z radiator was designed to cool a lager displacement 6 cylinder engine, and you are using a turbo 4. i would think a radiator of the stock size would have enough capacity to keep the SR cool, as long as it's a four row. the MSA rad. is sized to your stock radiator so you can still route your IC piping through the holes on each side of the rad.

 

i kinda had a random brainstorm that since the sr20 sits back so far, why not move the rad back about 3"-5" and fab up a bracket to extend the core support. that way, you can still mount the intercooler in front of the rad, but you would use a lot less piping, which, depending on the pipe size, can improve your boost response. they did this on their project silvia in scc, and their only problems were power steering and AC lines (which i wouldnt have a problem with having a lack of them). i dunno, just a way to move the weight a little less off thr front of the car...who knows? good luck with the swap though man.

Displacement has very little to do with necessary cooling capacity. Cooling jacket design, engine design, turbo integration, oil cooling, transmission cooler routing, etc. could all easily make a 4 cylinder far exceed what a larger engine requires for a radiator.

 

With that said, a 4 core rad close to stock size should be sufficent for anything you can throw at it. You might also consider an aluminum radiator from Griffen, etc.

true, i guess i just figured usually larger engines normally use larger capacity radiators....hah oh well my ignorance has been corrected.

 

not to highjack his thread or anything, but would making a new core support that sat farther back in the engine bay (since the sr allows a lot of room) be a bad idea in any way? as long as you made some ducting in the front so that the high pressure air doesnt miss the rad. i would think of this for the purpose of making shorter IC piping, taking a little weight off the front of the car (well, moving it back), and i guess just doing something different...any reason why not?

thanks

I'm using an alum. radiator that is 19x22 on my RB26 swap. That size should leave plenty of room to nagotiate IC pipes around it. My IC core alone is wider than MY radiator.
