Hi..

I dynoed my car like last week at ISmotor in Sydney and get 130rwkw only..

I only have SAFC ,3 inch catback, filter, bov on the car now..

When they dyno the car after 130 km the car start rumbling..

It runs 8 Psi all the way..

The mechanic said my coil pack and spark plug is not good,

so i ordered Splitfire coil pack.. they said 10 of 15 R34 have problem with the coil pack

But then i asked few people that when sumthin not right with the coil pack the engine light will show on the dash..

It confuse me now :D:thanks:

So Anyone have any idea whats wrong with my car..

Thanks in advance

Also how much power am i expecting from Tiptronic R34 GTT.. :happy:

man, that is seriosuly not good. 130 rwks? wtf? u shud have at least another 50 kws on top of that with safc, zorst and filter. post up ur graph man. btw, if there's a problem with coil packs, from my experience, the light wont show up.

I've recently run into this problem, it was indeed the coilpack not working but it was only half f*cked. The engine light couldn't come on but the coilpack would work/not work very quickly - this resulted in my car stuttering and missing all over the place. Might have to get a set of splitfires myself soon.

He said he got 15 Gtt coming to him and 10 of them got this problem..

And he own a GTR R34 and have the same problem..

Dont have the graphs cause i dynoed it to tune the SAFC but its unsuccesfull cause of the car giving problem..

100% sure or not.. The coils cost almost $1000, if its not the coil problem ill be wasting my money..i just paid the deposit and its comin dec 5 if its not the problem probably i can cancel..

So how many Kw normally if its a stock R34

Oooo, now I understand what your saying. I'm not one to speak but you need to structure your sentences a little better.

Yeah if you find you need splitfires get them from Nengun or Perfectrun. Should only cost you about $550 delivered and maybe 1-2 weeks delivery time.

If it was the coilpacks wouldn't the car be misfiring? Or can they cause other problems as well...?

Just a quick question.

I have seen all this posts with R34 and failed coilpacks shiting themselves.

R34's are only roughly 8 years and younger.

Are they a bosch unit? (Sorry i haven't pulled mine out to check)

I have worked on various Japanese car's as a mechanic and have never seen major problems with coilpacks.

Has anybody checked to see if there is somesort of official "service bulletin", similar to what Ford and Holden do to make diagnosis faster?

Cheers

Yup i have backfire in my car, and when the car gets hot it start to like rumble..

i just wish the splitfire will fix it..

I had that in my old CA18DE, swapped every single coil and in the end turned out to be the crank angle sensor.

Ended up getting one from one of the guys in my club, nissanexa.com. But i think it was about $150 for a good second hand crank angle sensor. Also it retards timing too if it's rooted.

I'm not sure how much it is for an R34, but if you find out let us all know. Still always good to get a proper diagnosis, swap out the coils first because that's the easiest to do. If you're planning on upping the boost by a significant amount, i'd still go the splitfires, because in the end you'll probably end up doing it so even if it doesn't fix the problem you wouldn't have wasted your hard earn.

My two bobs.

    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
    • OK, now we are ready to get started. You need to remove the air boxes on each side for clearance. The cover is straightforward, undo the clips on the top and lift the front cover out of the rest of the housing. If it is tight you can remove the air filters first. The rear section of the airbox is trickier. On each side you need to remove the Air flow meter wiring which is held to the airbox with a clip; you need to get behind the clip on 2 sides if you want to remove it without breaking it - unclip the harder side and pull on the clip with medium force, then unclip the easier side and it should pop out The airbox is held onto the intake hose with a spring clamp; you need to get a flat bladed screwdriver behind the spring on both sides and pop them outwards. When you have got them in the right unclipped place they will stay there and the airbox slips out pretty freely. Put a rag in the intake to prevent anything getting dropped in there, and also to prevent you seeing that the turbo seal is leaking oil (as they do). Then. The top of the radiator is held by a steel plate, it is secured by 2x10mm and 2x12mm headed bolts . Remove them and remove the plate Also grab the bushings that hold the radiator to the plate on each side so they are not lost!
    • Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.
    • Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
