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.

    • Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!
    • Got you mate. Check your email!
    • I see you've never had to push start your own car... You could save some weight right now...
    • Sounds good.  I don't 100% understand what your getting at here. When you say, "I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down" do you mean this - there is a panel with factory paint, without any prep work, they paint the entire panel with primer, then colour then clear?  If that's what you mean, sure it will "stick" for a year, 2 years, maybe 3 years? Who knows. But at some stage it will flake off and when it does it's going to come off in huge chunks and look horrific.  Of course read your technical data sheet for your paint, but generally speaking, you can apply primer to a scuffed/prepped clear coat. Generally speaking, I wouldn't do this. I would scuff/prep the clear and then lay colour then clear. Adding the primer to these steps just adds cost and time. It will stick to the clear coat provided it has been appropriately scuffed/prepped first.  When you say, "but the new paint is landing on the old clearcoat" I am imagining someone not masking up the car and just letting overspray go wherever it wants. Surely this isn't what you mean?  So I'll assume the following scenario - there is a small scratch. The person manages to somehow fill the scratch and now has a perfectly flat surface. They then spray colour and clear over this small masked off section of the car. Is this what you mean? If this is the case, yes the new paint will eventually flake off in X number of years time.  The easy solution is to scuff/prep all of the paint that hasn't been masked off in the repair area then lay the paint.  So you want to prep the surface, lay primer, then lay filler, then lay primer, then colour, then clear?  Life seems so much simpler if you prep, fill, primer, colour then clear.  There are very few reasons to go to bare metal. Chasing rust is a good example of why you'd go to bare metal.  A simple dent, there is no way in hell I'm going to bare metal for that repair. I've got enough on my plate without creating extra work for myself lol.
