Hey guys,

Ive been informed by a pretty knowledgable person pumping out a nice 240kws from a 4 door 34 that I dont need a FMIC if im not making 200+kws ..

Hes told me yes the 32 aND 33 greatly benifit from a FMIC whereas the 34 will be hampered with such a big FM is this true? i plan to get a blitz LM Fm and run to stock piping to reduce lag but dont want to lose alot of power.. I wont be using a powerfc just a S-afc Neo to re-tune the air flow/fuel as all im going to do engine wise is exhaust extension to from the turbo (currently runs 4" from cat and 4.5" dump) and looking at high flow 5" cat and twin dump/front

Also gettin Cold air intake box and pod.. and thats all ill be doing to the engine..

with exception to the fmic which im tossing up .. hes informed me that unless i wack in injectors and turbos etc I wont need to upgrade and im pretty confident hes right.?!

So what do you all think?

Big FMIC create LAG. The SMIC on the 34 is better than that of the 33 or 32.

Get your SMIC flushed and cleaned (if your car has had its fair share of km) and then you will find it will be quite adequate for 200kw.

Get a Intercooler rated under 550hp and you should be fine in terms of lag. Not sure where the LM intercoolers are good for.

All depends on what you want from the car...how much power you want to make and what do you want to use the car for...one thing is for sure...a fmic will NOT hamper the car if you get a good system on there......get an fmic anyway...doesn't have to be massive...cooler air can't hurt...

The R34 SMIC is supposed to be good at up to around 200rwkw. I've got just a bit more than that and I'm still using the stock SMIC. I think I will need to get a smallish FMIC when summer comes around as its very borderline now on hotter days with detonation and loss of performance. It's fine when its in the low 20's or cooler though.

With your level of modifications at the moment the R34 SMIC will be fine, don't bother upgrading the IC.

I find it best to have your car setup for what u want it for...

If u are looking at keeping stock turbo and pushing no more then 220kw then keep your stock SMIC.

Their are a few benefits to getting a frount mount and the main one i would say is its there for when u want to upgrade to more power. But you could save your money (for now) and keep the stock SMIC which will be perfectly fine for 220rwkw. And you wont get heat soak with it. With the setup you have described the stock SMIC will be fine and cheaper!

But if you do choose to get a FMIC, let me know and i will be more then happy to buy your SMIC off you!!

As everyone else has said, stockers are supposed to be good for 200kws but I definitely don't agree with the lag comments because I have no (noticeable) lag with my ARC core.

The difference in the stock cooler from the 33 to the 34 is its width... They do come with a SMIC from factory.

This is what one looks like.

The R34 Smic is rated to about 230kw atw and is a direct bolt on for the r33.

I just put in a r34 smic and hoping to reach the 200kw mark.

Although ive noticed that touching the smic after a long drive, it is quite warm. Whereas a fmic would be much colder.

If you are getting a doluck frontbar it might look a bit odd having a large gap in the front with no fmic there. Unless you mesh it up.

If you have no worries about the legalities of an fmic (in terms of cutting holes to pass piping if needed) then id go ahead with the fmic, esp with the front bar.

Sell off the r34 smic for $200~ to a R32/R33 owner :closedeyes:

^^^^^^^^hah you should really do a search but, fmic - front mount intercooler, smic - side mount intercooler

Ah, ok, thats easy enough, I've just never heard of those things in acronym form....

Leave the stock intercooler there for now. Until you are ready to go large power upgrades (bigger turbo), then work out what you are aiming at purpose wise.

The factory R34 intercooler offers better response over larger upgrade variants, the efficiency at your power levels can't really be improved on.

The whole lag issue is missunderstood. Even without going into the realm of it, if you spend money on something that doesn't make your car go faster then we call that a waste of money?

I would certainly look at the blitz/ARC or whatever once you decide you need a bigger turbo. Then you have an idea of the power goals and use for the car which will help you pick out the right brand/core type/size of intercooler.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • 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"
