I reckon that the most you would have to do is replace the tip with a slightly longer one. I don't know about you guys but mine is 5cm longer in the boot. That's not much when you think about it.

Mine is being fitted in about a week so I'll let you know what I find out then.

Some can, some don't. So better checkout websites like www.takakaira.co.jp or www.perfectrun.com.au as their online list is pretty detailed mentioning whether a certain exhaust will fit 2D only, Manual trans only or models with A-LSD etc. etc.

G'luck.

Jap coupe exhaust fits my sedan fine...  Only quirk is the tip sits slightly under the bar... at most 1.5inches...

There's a clause in regards to ADR or vehicle modification guide that states exhaust gases must exit within a certain distance from the last edge of a car's floorpan. This could mean all floorpan including the edge of your boot floorpan.

In your case, it may have caused the car to be non roadworthy, and when certain authorities start to realise this, there's a whole lot of new possibilities to defect cars based on this ground rule.

See Vehicle Standards Information 8 Section 12 regarding Exhaust.

The exhaust outlet must extend at least 40 mm beyond the furthermost outboard or rearmost joint of the floor pan which is not continuously welded or permanently sealed which could permit direct access of exhaust gases to the passenger compartment

The tip is still within the surrounds of the rear bar... I've got bigger issues to worry about...

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
