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.

      RB20 in need of modest love injection

      By GTSBoy · Posted

      As you're looking at using a Link ECU, then large injectors are not a problem. But there's not really any need to go 1000s on an RB20 unless you're planning >>600HP on E85, which would seem unlikely. There are other options for injectors. The Xspurt ones are available from a number of places and you can get them in the mid 600s and 725cc, which is probably a sensible place to be. These are all EV14 based. If you are not using the stock AFM (at all, which would be the case with a Link) then a large turbo intake pipe to suit the ATR turbos is not an obstacle, so you should use one instead of a highflow. Results will be better.

      RB20 in need of modest love injection

      By QB6SAGR · Posted

      Hey guys,  I'm after some advice and this here is the best place to get it imo. I was a member a looong time ago under another account, with a lost email address. Its nice to jump back on and see some of the same names still giving good advice.  I mothballed my car when i moved to perth in 2013, and after getting towed across the nullabor a few times it has officially done more km's on a trailer than under its own power. Now that i have started the process of tidying up and modifying it, i see the fruit available (and the fruiterers selling the produce) is different than back in the day. hence my questions, as i used to 'know' what to get and now, i'm not so sure. Engine wise the car (92 gtst) has a walbro 255, k+n, fmic, cam gears and and turbo back 3"exhaust. Wish list is a Hypergear high flow or ATR43G1, Link G4x and some newer injectors before a tune up. My goals are modest, only low 200's power wise. i know i could achieve this with less, but i've been swapping out old for new where i can. Every cooling hose has been replaced, along with mani gaskets, WP, thermostat and radiator, fuel pump and timing belt, tensioner and idler, and i rebuilt the steering rack. Regarding the injectors, the fruiterers all seem to sell what used to be considered quite large injectors. There are a lot of options for bosch 1000cc EV14's, and i would like to know if that is a suitable choice for my build. Is modern injector design good enough to run these at the low duty cycles that i likely would be? is there a downside to running a too large injector these days? or, would there be an upside to running a smaller injector at higher duty cycle? I can see that there are smaller injectors still available, but the ones i have seen specifically marketed for RB's are pretty large (see: https://golebysparts.au/collections/fuel-rail-injector-kits/products/nissan-rb20-fuel-rail-bosch-980cc-1150cc-injectors-turbosmart-fpr800-regulator-kit), and i dont know enough about them to say one not marketed for RB's would fit or not. I have searched the forums, and amongst all the posts on older tech, I did see gtsboy recommend EV14's, but no size was mentioned... again, i'm not clear on if the smaller size bosch injectors are also EV14's as they do look similar.  also, if someone can recommend a tuner familiar with RB's in the Geelong or West Melbourne area i'd appreciate it. Thanks in advance guys. Cheers, Rowdy

      R33 GTR lift points for hoist

      By Duncan · Posted

      FWIW the depth of the groove in the rubber pad is not super essential, the blocks are rubber and squish a bit. If you are worried an angle grinder will make a deeper groove quick smart

      R33 GTR lift points for hoist

      By GTSBoy · Posted

      I mean, if you were to move the jacking points away from the original location, that is, away from the wheels and closer to the centreline of the car, then it will be more likely to overbalance and tip off the supports. Same as we talked about before. I was talking about moving for-aft. If the sill is bent outward or inward, then the car would obviously look unstraight from the outside. Hopefully that hasn't happened either. Again, you can do comparative measurements from the chassis rails to see if there is much deflection.

      Can you elaborate what you mean with your first sentence? I meant move as in the bulge kinda seemed like it got pulled "outward" meaning it got pulled down and to the side with the jacking rail itself, so the load bearing bulge now sits lower than usual and is not level with the sill on the other side of the jack point. Either that or the jacking rail just got pushed in a good bit.
