yeah dude go for it....i fitted one last weekend.......

few things to note.

*search for the instructions to fit a hybrid cooler. it has pretty much the exact location to cut the hole...i cut mine a cm or two further back so i wouldn't have to trim the fan.

* there is no nipple on the piping for the boost control.....i just tapped a thread in the piping and used some loctite...to seal it in there

* headlights were a bit of a shjt to get back in....had to modify a little bit.

* Angle grinder and jig saw are your best friends doing this job

Good luck man....if you need any advice throw me a pm as its still pretty fresh in my mind.

I fitted one today actually!! Felt a huge difference.. Seems like turbo spools up a lot quicker :)

Haha... I felt no difference after putting on 34 SMIC. Didn't really feel a difference when I installed 3" turbo back either! Maybe I just need a tune.

What engine management you running now Sid?

you get what you pay for...... :D

thats true to a point but then if thats the case and a ferrari spyder is our benchmark (as would say a hks intercooler kit) then i guess what you are trying to say is we all drive peices of shit!

i dont htink so...its all about application and practicality. you wouldnt put a diamond incrusted turbo on your car would you now...'but it cost more so it must be better!' un no thats not the case.

anyway, for most people.. you will find the just jap intercooler kit more than adaquate!

ive fitted them to a few cars before, you do get what you pay for to a certain extent as far as the finish goes, some of the pipworks needs a bit of stuffing around to get the where its suppose to be which you wouldnt get that with a hks, arc etc kit but for the money you pay for them they are pretty good for a everyday street car with a bit of extra power, so as long as your not looking at huge amounts of power you really cant go wrong with them, so long as you dont mind some things ill fitting, just work around it :D

anybody felt their car NOT going so well after puttin 1 of these kits on?? friend of mine recently put 1 on his 33 4 door, and he swears 1st/2nd gear do not pull as good as before, but 3rd/4th gear go like all hell! Had it dyno'd to check the afr's and its running well rich, and only made 165rwkw on 11psi! changed the plugs to bcpres 7's (i think it was, 7 heat range thats for sure) but it still does not go that well in 1st/2nd. Any ideas? He's has read somewhere that a SAFC might help a fair bit?

Sounds like your friend did not install it properly, or he has other issues which are causing the performance problems with his car.

he'd do alot better with engine management and a tune. safc should do the job

i just installed my JJR type 1 kit on my r33 in the last few days. bit of chopping here and there and abit of stress but it all worked out fine. took it for a run last night and i felt an improvement straight away. feels more torquey down low. definately a good buy. took a day and a half to fit it all up by myself

to the dude that fitted a r34 smic and didnt feel much improvement, did you clean it out first? im not trying to stir, just curious.

Yes I first filled it with turps several times and shook it around, left it sitting awhile, then used metho to get rid of any residue.

Honestly I didn't expect any improvement and don't see why it would improve (well not noticeably anyhow). Except if you are boosting it for long enough that the stockie gets heat soak which I don't really do... The reason I got it was to be on the safe side.

I had a just jap 100mm tube and fin cooler for my R32 GTR and i pulled 335rwkw with it on. It is ok but doesnt seem to like the repeated dyno runs when she has been pushed.

It seems good to get to this power but i am changing to a Trust cooler only because i am changing turbos which will get me to 400R+rwkw ,and we felt this cooler was not flowing enough to go beyond this point, but hey for 300 odd dollars to get to this power is still great mind you i still have the standard rubber piping i just replaced the cooler only.

Also any one interested in a 2month old jjr tube and fin cooler i will be selling it cheap $250 still like brand new i live in Sydney.

      V37 Suspension change

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

      Duncan's V37.......race car?

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
