Does Any One Know Somthing About My Problem


Recommended Posts

Hi

i have a 1996 r33 series 2 Gts-t and i have had some problems with it after i had the following dump/front pipe and a tune done by a workshop. I took my car out and after hitting high revs then backing off the accelerator suddenly my cars idle droppes below 500 and fluctuated and the engine shakes and It seems that my car is using more fuel then it used to HELP!!!!.

So i tried to see if i could fix the problem. .. I changed to a high flow fuel pump, changed the fuel filter,installed yellow jacket coils and plugs and air flow meter was changed and even the ecu was changed but still same problem.. after all this i took my car to a skyline mechanic and he still could not find the problem :angry: can someone please help me I've spend nearly thousands of dollars trying to sort this problem out but it seems its a mystery

BTW the car runs Ok at low revs but once you hit high revs the car begins to play up.

Mods

FMIC

Full Turbo Exhaust System

High Flow Fuel Pump

Standard Ecu

Yellow Coil Pack

Boost Controller (10psi)

Cheers

How could they tune your ecu if its standard? Unless you have the Nistune board added to it.

As for your problem it could be: Worn CAS, Air leaks on intake side.

Can't really think of anything else at the moment.

you are probably seeing over 10psi and going into rich and retard mode.

your ecu will be retarding the timing majorly as the stock setup is not designed to take 10+psi

some cars do it at 10psi, some at 12, etc etc

but it's always around 10

try dropping the boost and seeing what happens

also what kind of a "tune" did the workshop say they gave you with a stock ecu?

My question is, if the car start exhibiting these symptoms after you modified it...why on earth did you go replacing everything else in the engine bay instead of checking what you just changed about the engine? Should have taken it straight back.

Could be the wastegate not opening up enough = R&R mode. If it's one of those el cheapo split pipe dumps, welcome to the world of rich and retard. Disconnect the actuator arm from the wastegate periscope and see how much movement there is for the flap...it should be able to open a full 90 degrees, if not more.

You would have to be a retard to rebuild the whole engine when it may have been an electrical fault and spending thousands rebuilding the engine may not solve the problem.

If you want to do the throw-money-at-it-until-the-problem-goes-away solution, buy a half cut or a long motor for $1500 and transplant everything.

i suggest calling my friend henry and see him about it he helped me heaps with my car say i sent you, Bruno, Cosmic performance 0422 117 168

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
