So I have the APS single turbo on order for my 05 coupe 6mt and I have the Stillen front fascia for the intercooler. I want to do a few other things to assist with keeping things cool and under control in the engine. This car is my daily driver, I also drive this car alot besides going to and from work to include frequent long recreational drives and several trips a year out of state with my wife and son. I consider myself to be in between a moderate to fast driver. I dont street race nor have I been to the track. Though the track thing will change with the turbo addition. I decided to order a Stillen oil cooler (will that even fit with the turbo?), 18lb nismo radiator cap (stock is 13), Nismo low temp thermostat which opens up at 154f instead of 170f like stock, and of course the 1 step colder NGK iridiums. Do these items sound like good additions or am I over doing it?

OK...

1. One step NGK's or Denso (IKH-20) are good.
2. The rad cap..sure, but not essential. If you must, and don't care about the looks, get one from AutoZone made by Prestone for about $11.
3. Do NOT get a thermostat. T-stat prevents your car from runnign too cold (which, yes, you CAN run too cold), not from overheating. When youare near the 212degF boilign point, the T-stat is already wide open..so it's the radiator cooling capacity that is going to keep you from boiling over.
4. Oil cooler is good to be sure, jsut make sure it doesn't cool things down too much, again. But, yes, it's a safe bet.

You are missing one thing that is important. Instead of getting a $140+ t-stat, put your money toward a Koyo radiator. I know that they don't fit really well...but you should get it nonetheless. It's a must at the track with a TT kit., or with prolonged fast driving.

Of course a very free-flowign exhaust AND test pipes should be VERY high up on the list as well..in fact, the first thing you should get are those items, followed by a radiator, then an oil cooler, then a radiator cap (and the t-stat should NEVER be a part of it).

HTH

 

Ok thank you. I already have the 3inch Fuji exhaust, the aps st eliminates cats all together with its single pipe back to the midpipe.

 

That MAY be the understatement of the year. Expect to spend as much installing it as you spent on buying it.

Unless you plan on installing aftermarket fans with it! My shop used my stock fans and they had to shave down the actual blades of both fans to fit between my ic piping.

I will say it was WELL worth it though, not a single heat issue to date.

 

I agree completely.

Mine is a Griffin unit, which fits far better now from what I understand....Mine was a semi-prototype, and it took 6 hours to install. But the results are incredible...under full boost at 12 psi for minutes at a time, temps never go above 205!!!

 

So, the Griffin radiator fits without much, if any fabrication? Is there a website for it? (I can't seem to find it)

Thanks
Dave

 

The thing is that it's designed for the 2003 5AT sedan, it has the additional AT cooler built in.

griffinrad.com

 

Well, that will prove somewhat un-useful for me, then. Thanks anyhow.

Get a 350Z PE radiator. It is a direct fit other than the top mounting brackets. It costs little more than the Koyo, but in the end after you pay for the extra labor on the koyo they will cost about the same. The fans or shroud do not have to be cut in order for the unit to fit correct.

 

ur gonna want to ditch the fuji....... trust me. as big as the piping is, it doesn't flow as well and does'nt let the aps st flow as well. i tried to keep the fuji but ended up gaining 50whp and 40ft/lbs. of torque by going to the jic. sux, cuz the car is louder now (no more sleeper status), but the increase in horsepower was worth it.

 

GMAN what did you with the top mounting brackets to make the radiator bolt up properly?

bullitproof dont be a buzz kill man, I refuse to believe you... *sigh*

 

It seems like most people have the mounting pins cut off and rewelded. However, my shop fabbed up some polished brackets out of some ~0.75" square aluminum.

If you need a place to source the aluminum brackets you don't have to look further then your own front bumper.... There are roughly 6 to 8 small strips riveted vertically to the front bumper. I drilled out the rivets, cut off the mounting tab, drilled some holes and my installer polished both brackets for a very stock look.

 

Hey blue, i did'nt wanna believe me either, but the numbers don't lie. the boost would bleed off at high rpms with the fuji. the jic lets the turbo spin with minimal pressure and holds the boost at 8.5 psi. i sold my fuji to one of the members on the forum for about the price of the jic. once i get it tuned, i should get 400whp at 9.5 psi. you'll see..........

 

I was checking out some exhausts similar to what you got. Them things are loud, i dont think I can stomach that as my daily driver, nor will my son like it.

 

i'm getting used to it, i guess. everyone else likes it but me. sounds really, really mean. i really liked the fujistubo but a 50whp boost and stable boost pressure won me over. if you look at the aps st kit, the connection from the downpipe to the exhaust is a reducer pipe and might be the bottleneck in the system. you could try cutting your pipe and connecting the fuji directly to the downpipe might fix the problem. i didn't want hack up the fuji and lose money on the resale if it did'nt work. it might work, it might not. the jic definatley works!!!!
