Yeah the r33 probably different cause mine hangs low and its put perfectly and note this was after I even modded the dump pipe higher to push the exhuast up as much as it goes and its still pretty low.

Curiously does anyone have a regu 92-z system? Wondering if these older systems have the silenced in the rear cannon as well. I believe this was the model preceding the 06 & r system

i'm sure the 92z do as well, but i dont know about the 96r. 96 is louder than 92, i'm not sure what the physical difference is between the two, it might just be a difference in terms of the size of the strictor, or that one has restrictor one doesnt

kakimoto states on their website that 06R is a hybrid of 92z and 96R + the titanium looking tip

but i was told that 06R is just 92Z with the ti look tip, the db rating on kakimoto's website is 93db for 06R, so it kind of makes sense, but i've never compared it before

In regards to difference well when I took my car checked with the regu06 fitted when it still had the restrictor it was definately causeing a restriction it did not like the extra timing I had in my tune from my previous exhuast and it was pinging I havent had it put on dyno with no restrictor but in regards to how it feels certainly feels alot more responsive and free revs better and seems to boost better.

In terms of noise yes it did get alot louder as suppose to before its not quite as loud as my old one which was is a stright pipe exhuast with a cannon on the back but its still much louder than it was with the restrictor so that middle muffler on it doesnt do shit lol thats why they stuck a reducer in it.

Now I see why racepace wanted 3500 for a custom exhuast that would flow and be quiet cause its not possible to find one for cheap as this kakimato has shown.

any more updates?? any dyno time, worth doing?

does an oval resonator restrict flow over a hotdog type one? and what size dump pipe should be used with gt30's, does the flange support a 3inch only or could it go upto 4 inch?

Well without the restrictor the old timing that it had could be added back in was a difference of around 10 kw

what was the max power your car pulled with and without the restriction?

10kw from 300kw is actually not as bad as say 10kw from 200kw..

update: removed the restrictor out of the kaki regu today, definately is louder, havent driven at WOT yet as i wanna get it on a dyno to make sure its all good first

took some pics on the way incase someone is thinking of doing the same, took about 2hrs all up from removing the exhaust to re-fitting it, used a dremel to cut it out, the restrictor as mentioned is 2.5" and roughly 20cm long

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
