Okay, here's me all excited and bum up installing my intercooler that came today. Now I have a problem though ... I have come to the stage of fitting the top pipe and the destructions say to "Trim the fan blades down !" but when I look at it and size it up, it's more like " Hack the fan blades to death ! "

So, the question is, cutting the blades down until the top pipe fits in nicely, will this raise my engine temp at all ? Seems to me there will not be much left of the fan if I do. Should I remove the fan and wack in some thermos instead ? :laugh:

i had to do thesame on my R33. What i did was to get a texter, and mark up the top of the fan to cut off. I did this by holding the texter fixed, and then rotating the blade. I did this at the top and then the from the side inside the engine bay. This gives you two lines and if you join them, you get a triangular shape, about 3*5cm. I then pulled the fan off, 4 bolts, and used a grinder with a very fibe cutting blade, and trimmed the blades. Cleaned them out with some sand paper, and hay presto. The fan is still very balanced, a little noisier, as the curved tipps stop cavitation.

Hope that helps

Hey ive had mine installed now for a few weeks, and i had to remove the neo cover, and trim the blades slightly,

i havent noticed any differnce what so ever in performance or engine temp.

LOL just use the process of natural evolution... install the FMIC, close the bonnet and pray for the best. After 1000kms your fan will have either exploded or formed into a perfect shape for your FMIC Pipe :D

Nah, just mark it out with a pen and take bits off with a dremel... remember this though, take off LITTLE bits at a time... you would rather waste time doing little bits than to waste the fan / performance by taking of big bits.

Sweet thanks bud :D

EDIT: What did you do for a water bottle ?

it's not performance nor engine temp you'd be worried about bryn, it would be not trimming them evenly.. centrifigal forces on an unbalanced fan can get pretty carried away if you don't do it properly :S i managed to keep my piping out of the way with a bit of playing around, ended up throwing a zippy tie or two around where the L shaped pipe bolts to the drivers side of the head as my dodgy piping didn't come with the mount welded on, and accidently snapped it playing around in the engine bay with the engine running one night and the fan blades trimmed themselves perfectly on the sharp edge of the pipe clamp >_< good times, good times.. definently remove the neo cover though

EDIT: About the water bottle - he doesn't have one anymore :)

R34GTTs will require you to either modify the stock washer bottle (which is a royal headf**k) or go and get an aftermarket replacement from Supercheap or similar.

We get a $30 generic one which fits next to the battery making it look rather OEM actually. I must say, the capacity of this is like 1L so don't expect the same amount of "squirt" as the stock item >_<

Washer bottle will be installed on the other side... where stock cooler once was, once im bothered enough to take bumoer off again

hehehe self trimming fan :cheers:

so what u end up doin..?

the trim job or.. let her do her thing..?

u found no performance gain in having a FMIC? my GTir Saw a noticable gain.. some what 20kw ontop when she boosted to 16psi and advanced timing... but she used to have an old shitty top mount interwarmer with oil in it. :)

yay for rally cars.. mini GTR :)

Thanks guys I have finished it today, she's up and running. Didn't have to trim as mush as a thought. Neighbour thought I was a bit mad when i started the engine and held a sanding block to the edge of the fan :) this was after the beers kicked in. Looks KO to me .

hmm. on 12psi on the GTiR u get a nice boost in power. noticably quicker. on 12 it allowed me 2 pull 2 carlengths infront of my mates GTS25t running 14psi.. haha. and the 16 saw me over the horizon. so i guess the TMIC setup was just too wasted. maybe u dnt get power increase with the fmic. but cooler charged air should always give more power..

I have been out and about driving and noticed the difference, nothing astronomical but a definate difference.

At the same time paranoid about a hose/pipe blowing off, so I put my whole garage in the boot just incase :woot:

I will be going a new radiator and thermo fan next week getting rid of the MixMaster.

Nothing yet bud , thinking of welding up an aluminium one. :) A Big sucker too, something that I can brew beer in. :woot: and link it to water spray for the FMIC aswell . Alot in the works for the grey matter.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 馃
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
