Hi all.

I have an R33 S2 GTS-T Manual

- Fully services with new plugs (0.9 gap heat range 6 NGK)

- 3 inch Turbo Back exhaust (bellmouth type dump pipe)

- K&N Pod (clean AFM regually)

- R34 GT-T SMIC

The car runs great, real smooth, good on fuel (98only), NEVER backfires, misses or splutters!

Note the car runs std boost (confirmed with an aftermarket boost gauge) but I have done the free boost mod (gives 7psi through the whole rev band, not the factory 5/7 method)

Now my car seems to suffer from mild R&R on really cold nights (sub 10degrees, which is common in melbourne at the moment). The car will take off hard, flatten in the midrange, not misfire just seem flat, then pick back up in the top of the rpm band.

Tonight I took off from the lights, got into second (had three people in the car, more load than usual?) and at about 3000rpm I stepped on the pedal (to show off a bit :P ) and the car took of then, bang, hit some sort of hard cut. It was like I rapidly took my foot of the accelerator andthe whole drive line banged. After this the car drove fine but I didnt boot it again as I was worried.

What has caused this and what is it? R&R? Boost cut? (because of the 7psi in the midrange when it expects 5?)

Any thoughts?

Also someone said that all ECUs respond differently to this mode, mine seems sensitive as all it takes is a cool night to carry on yet some people can run 12psi in winter with no problems and more mods than me??? Is it worth swapping my ecu for another one?

thanks!

Bite the bullet and get an aftermarket ecu now - Link, Vipec, PFC whatever. Then you can put boost up to 10psi and the car will run heaps better. Later when you want the bigger turbo etc etc you will be able to tune for it.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • 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.
