radiator relocation - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

weissguy · 10-30-2011, 08:17 PM

I swapped a 2jzgte into my s14 and it has barely any clearance between the radiator fans and the front of the engine. Its so close that I think the air cavitates and is affecting the cooling efficiency of the fans.

I was looking at the car and I think that I could re-locate the radiator underneath the radiator support area. Has anyone ever seen this done before? It would move the radiator forward a good 3 inches or so.

Tips would be helpful.

Sileighty_85 · 10-30-2011, 08:18 PM

either that or put some pusher fans in front of the Radiator

ill. · 10-30-2011, 08:29 PM

Air cannot cavitate.

But it will be sucked straight toward the engine and be going nowhere.

LUCKYxS13 · 10-30-2011, 08:40 PM

What I've seen some people do is cut the rad support and move the rad up a little. But im guessing you won't be into cutting the rad support!? Then again stick the rad underneath the rad support would be a good idea.

weissguy · 10-30-2011, 09:19 PM

I am willing to u the radiator support if necessary. The car runs at a good temp and does not overheat but I need the extra space to make it more efficient.

Another problem I have been thinking about is the location of my condensor if I move the radiator...I guess I may have no option but to leave it where it is at. are pusher fans as efficient as puller fans?

thefro526 · 10-30-2011, 09:28 PM

Chasebays sells a rad that fits in the core support.

Should net you about 2" more clearance.

LUCKYxS13 · 10-30-2011, 09:30 PM

Personally, I think pushers block air flow when driving on the highway or any road in that matter. Also when people cut there rad support, I didn't see them do anything to the condenser.

My pushers work just fine with my RB, also still have the A/C condenser in the stock location

I am also looking to move the radiator forward. My Turbo LSx S13 likes to get hot because it now has a 4" intercooler in front of of the radiator and a 2.5" crossover hotside behind it. I was thinking about notching the top of the core support and notching in between the headlights to make a nice seat for it. I'm going to go stare at it more today.

Slo_240sx · 11-08-2011, 05:17 PM

Bumping this thread...

I've been staring at the core support for a while now. It looks like you can notch the lower crossmember of the core support. I am thinking about drilling out the upper support's spot welds and using M8 bolts to fasten it back on. I'll get up pics once my Flexalite fans come in.

2.5T_/<ouki · 11-08-2011, 05:30 PM

I have just the solution for you. You can do the pushers, however i didn't go this route and i too was faced with a situation similar to yours. Let me snap a pic for you. Mine is in the radio support.

EDIT: Here are some pics i just snapped of what mine looks like. Please excuse the dirtyness :P. Been working on her lately and no time to clean her off!

mantas · 11-08-2011, 05:39 PM

I'm in the same boat with my RB25.

1. Chasebay radiators.....not gonna go that route, no way i'm paying $400 for a radiator unless it's made out of gold.
2. Cutting looks like shit and i'm wondering if this affects "flex or geometry" of the car?

Mitsubayati · 11-08-2011, 05:41 PM

I like 2.5T_/<ouki's fix better than The chase bays one because it keeps the radiator at a higher point in the system.

Lol at the air cavitation comment. That's a fluid property.

Did you try fitting a clutch fan in there? What kind of mounts are you running?

I'm on stock r33 mounts with an r33 cross member and my steering column is an issue as well....not quite sure how to fix it besides doing a custom elbow...

I am also on r33 mounts w/ r33 cross-member. You need to get a Psyko performace elbow. They run about $200 picked up; it did the trick for me.

Fred Allen Burge · 11-08-2011, 05:54 PM

This is how I'm doing mine, from Summit for $250 or so.

2.5T_/<ouki · 11-08-2011, 05:56 PM

^ Looks good, but is that sufficient enough for a 2J ?

Look at how thick it is (no homo). I heard they do work fine on RB's. I tried contacting PSYCHO! (Syko) Performance and they never responded - guess they don't need the business in this economy. If I can't find one soon i'll just have a friend weld one for me....should be a fun project.

Btw, nice engine bay you have, what kind of tune you running?

Contact Marco @ SR20 Store in gardena. I picked mine up from him. Guy from Syko dropped it off at his shop and i picked it up from him for $200 cash.

Thanks!

Actualy i am stocker right now. In the process of installing my Z32 ECU & NIStune board.

I hope so, I'm putting in a LS1!

jdm styles · 11-08-2011, 06:56 PM

im also in the same boat i have a 1jz in a s13 and want more room and cool temps .... i use the car mostly for drifting so theres not always a good straight through air flow coming at the rad ! was thinking v mount . cant find too many pics with this setup though

pandaroo · 11-08-2011, 07:05 PM

^^^here you go man this is from s14pits build.

Fred, do you have the part number for that radiator? Looks perfect. I wonder if flexalite fans will mate up to that.

Too legit to quit!

Slo_240sx · 11-09-2011, 01:06 AM

Gotta move this guy forward to fit some puller fans. Pushers aren't cutting it with a 4" intercooler and a 2.5 hot pipe behind it.

240sxvaj · 11-09-2011, 01:54 AM

use a civic radiator

Here ya go, AFC-80107N from Summit. I think I'll have to run a surge tank to get it to bleed right, might get away with just putting a rad cap in the upper rad pipe but it's iffy.
