In my R33 skyline the clutch in my fan has had it.

I was thinking instead of replacing the standard fan i should just throw in a thermo electric fan

was thinking one 14" fan

or should i have 2 smaller ones?

any advice would be nice

thanks

i dunno if this is the case with the skyline motors but in the old holden motors (253ci,308ci) disabling your engine fan and using thermos can increase hp (less drag, more efficiant)... slightly

anyway... are you putting one/them in front of your radiator? or infront of your engine?

Dont install two small ones unless you use the EF/EL setup that comes with the shroud. Other than that a single 16" fits the factory shroud and will flow as much if not more than the factory crank fan.

Theres a DIY that gives the part number for the radiator sensor you'll need as well if you chose not to use a fan controller.

infront of the engine

one 14" would fit nicely

I'm using a Craig Davies 16" drag racing fan flows 3800CFM with a 90C Degree thermoswitch

cost me $280 for the fan and switch

All mounted on a 55mm thick 180SX radiator with custom top pipe, works fine :) keeps the temps down, I even drove my car without the fan wired up, round 30 minutes and it never hit over 1/2 way on the temp chart :S

Oh and it does have a bit more go :) it's not dragging like it used to, but that's because I stripped the aircon as well i thinK :)

total gain from the fan would be in the area of round 5hp i think

You might want to check into this a little more, i did the same conversion on my old rx7 and the cooling of the thermo was shyte (was a 16" davies craig) , would not do any where near as good as the clutch fan and have since heard many stories about many different cars that are driven hard and the thermo's dont work anywhere near as good as the factory clutch fan, i had my temp controller turned up full and if i drove normally or babied it it would sit at normal temp, as soon as i started to give it some it would shoot up, i would only need to do the equivalent of a 1/4 mile run and the temp would be up.

the best solution is a FLEX-A-LITE dual system part number 220 these pull 2500cfm (davies craig seem to rate their fans way off!! as twin davies fans could not keep our car even remotely cool) the 220 keeps our drift car ice cold, i run a pivot fan controller but am working on a cheaper alternative.

The fans are the same size as the skyline radiator and have a rubber seal that seals against the rad surface.

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
