Question for you guys running a 2JZ clutch fan and 7M factory shroud.

[fstlane88]

How close is the fan to the shroud? I'm thinking mine is too close because, under anything but light braking I can hear it hitting the shroud not hard but, enough that I can hear it.

I've already tried pulling the radiator back and custom mounting the radiator mounts and, am thinking now that the waterpump pulley that I am using isn't right for the setup. It's one of those from the generic aluminum sets (pic below) and I'm thinking I need a OEM TT waterpump pulley.

So before I go and order another pulley, I was wanting to find out if anyone else has had any fitment problems.

i did a while back. the first time i hit really hard boost i broke the fan and shroud. i replaced the fan but never replaced the shroud. had no issues since.

odd, mine sat too close to the waterneck but i did have mine pulled a little closer (the rad, see my brackets, for clearance for the intercooler pipe though)

 

[fstlane88]

That is really wierd, it's gotta have something to do with the pulley. I defintely can see from your pic tissimo that I can/need to pull the shroud in a little closer to the rad, but my fan defintely sits way closer to the rad than your setup. I'll try to get pics tomorrow, the batteries in the camera decided to die tonight as soon as I walked out the garage.

try to find yourself a GE fan blade, i had to put a couple washers on the clutch to space the blade out, but it sits plenty back, now i just need to find a shroud

mine fits fine. (2jzgte fan+clutch 7mgte shroud) i just hacked some of the a/c side off the shroud so my IC pipes would fit.

edit: i have the 2jz though not much of a fitment issue there i guess i have more room than tissimo did in that pic

Same here had no problem with mine. Not using after market pulley though. I'll get some pics when I get home.

 

[tlo86]

i am using that pulley it shouldn't really make a diff (my sc swap used oem)

Tissimo is using a NA fan. The TT fan sits closer to the radiator to fit with the water neck. The NA fan sits closer to the engine because it doesn't have to clear the water neck. If you are using the 90+ factory mounts the fan will come close to the shroud and may hit. If you use the 98+ style mounts the fan doesn't move forward under hard braking. The Other way to do it, is to cut the water neck and move it a little bit back and use a NA fan, or notch the core support and lower support and move the radiator two inches to the front of the car. All of this will only work with OEM style radiators.

I'm using all 2jz components with 7mge rad and prolly why it fits perfect.

 

[fstlane88]

I just can't win...I finally get a fan that cools worth a damn and now I have to cut my upper and lower radiator supports, and custom mount the radiator for it to not hit the shroud under braking.

If I'm going to go through all that I'm going to make it work with a big aluminum radiator as well.

It would be soooooooooooo nice if I could do ONE thing on this car and not have to do five other custom things along with it for it work properly....But I guess that's how it goes.

I bought it from a guy that had a 94TT that went electric? so who knows. I still have it though if you want it fstlane88? give me an offer

it worked fine, no issues, cept was just close. It used to touch the rad hose clamp, but it wore the fan down, haha.

I'm really good friends with one of the local engine builders here and the thought occured to me....Could I have that pulley machined to gain some clearance?

doubt you could do it enough to make a difference

I have my 1j equipped with the DM pulley and I have the 2j-tt fan and clutch inside the 7m shroud and it seems just fine.. odd.

 

[fstlane88]

Dylan could you take pics of your fan in the upper part of the shroud? I'm curious to see how close the blades are.

Absolutely.. I wont be able to post them til monday though, apoligies. It should help you out a bit none the less though.

 

[fstlane88]

No worries man, whenever you can get them will be cool.

 

[Dylan JZ]

here was when we had mock up for my piping:

no problems hitting, plenty of clearance.

lookin good! err and lookin exactly like mine Lol
