To R34 GTT owners;

How well does the R34 GTT smic handle on 200kw atw tunes?

Any problems with heatsoak on track days and/or long periods of spirited driving?

I currently have a r34 gtt smic on my stock r32 with plans of 200kw~ and was wondering if it will be reliable enough for the above.

People have rated the r34 smic to a maximum of 230kw~ atw but not many have mentioned about heatsoaking issues.

Hopefully there are a couple of r34 members on here with stock smic's pushing out 200kw with no probs?

Trying to decide wether i should install a intercooler waterspray ;)

cheers

Think you should install a intercooler waterspray or go FMIC cuz i reckon even at 180kwrw the SMIC isn't doing such a great job for my GTT R34 especially in summer hot days...

thanks for the info ;)

any other r34 owners with similar experiences?

My car currently has 160kw and havent encountered any heatsoak yet, although not sure how long that will last once i go past 180kw :D

What about improving ventilation around the smic? Like creating more airflow through bumper and undertray mods. I think cutting some small holes in the cover behind the smic will help with heatsoak.

What about insulation (i.e. heat tape/wrap) to keep heat away from the smic?

I reckon these will, at the LEAST, slow heatsoak down. The water spray is good, but i reckon is more finicky.

Not an R34 experience, but may be helpful...

I have an R34 SMIC in my R33, I have full 3" Turbo back exhaust, split dump pipe and Apexi Intake, high boost mod..

Not sure on the power, but at a guess the same as everyone else with these basic mods.

After a "spirited" drive, iv gotten home and thrown a hand on the back of the SMIC (i am missing the inner guard due to R34 SMIC girth and failed clips) just to see, and it is hot.. i mean HOT.

Normal driving on the open road with plenty of boost its similar. Its only cool when i dont give it stink.

One problem i can think of is that the Apexi intake is also very hot, IE sucking in hot air, as i dont have an airbox around it yet.

I dont feel any heatsoak issues or anything like that. It never hesitates or anything.

i got a 34smic on a rb20det 165rwkw and after 'you know' i've stopped,got out and touched both end tanks of the cooler and the hot side was warm to hot and the cool side is suprisingly cool. my experience.

I Ran into heat soak issues on the Dyno at 185rwkw on my R34 with the SMIC on a cooler day it might have been alright. Tuner had to leave it at that since it wasn't doing its job past 185kw went back with a FMIC and he tuned it to 210rwkw straight away.

In summer side mount is crap kills car power heaps.. Had one ditched it in winter, heading into summer because I couldnt handle it any more.. Fmic IMHO is alot better ..

If not use a alcohol or water spray over the cooler however it wont do much because it evaporates quite fast on a hot day. but will help!

Pat, just bite the bullet and install an FMIC with a return pipe that uses the stock hole, don't run a pod and you'll be street legal. and rig it up so you don't have to cut into the bumper support.

failing that, how about two SMIC's :) it'll drop your pressure a bit, but its still legal :)

if anyone is looking at getting rid of there 34 SMIC, please PM me as im keen to purchase one

i find my 34 SMIC made a difference when it comes too heat soak compared to the standard(r33 size) cooler. Also feels more responsive.

heat soak on a dyno is due to the fan not directed to give it enough airflow, this doesn't happen on the road.

In short it's not a problem you should be fussed about. Getting traction and brakes are worth more stress and effort than this one on a stock turbo.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
