R33 Gtr Beaten By Pensioner Driven Camry

Hi Everyone,

I have come to another obstacle after a cylinder being dropped was solved yesterday. It is a stock R33 GTR, the problem is that it stops revving after boost hits about +3.5 on the GTR gauge as pictured:-

Also it usually happens around the 4,000rpm range and upwards as pictured:-

THE PROBLEM

* Happens through out all gears. So when driving the car starts coming on boost, it hits roughly around the +3.5 mark and you can hear the roaring from under the bonnet, it doesnt rev anymore, i try to drive it out, but nothing, i have to bring it off boost by taking the foot off or changing gears.

* The car was running about 15-16L per 100km previously and doing 300-350km per tank. In the last 2 fills the fuel consumption has become 22-23L per 100km, it drank 54.78L over 239km which is ridiculous.

* The oil temp is slightly higher then what it used to be also. It would have been approx 90-100 degrees before and now it might be 100-110 degrees

HISTORY

Since having the car a less then 2 months ago. I have changed engine oil - engine flushed, oil filter, spark plugs (on the 4th set), air filter, fuel filter, coolant - radiator flushed, made sure all coil packs were healthy, made sure all fuel injectors were healthy, made sure ignitor module was healthy, made sure ECU was healthy, this was due to a problem which was sorted yesterday. Also had to replace the rear muffler with another original unit and fix the leaks in the front of the stock exhaust system. Obviously the cat that came from japan was changed for a new one when it was being complied. So exhaust now has no leaks.

Other things which were changed i dont think would effect what is happening is stereo head unit, front speakers, machine brake rotors, bleed brakes.

PREVIOUS PROBLEM FIXED:- 1st Cylinder Down

If anyone has had similar problems, or would know of a fix please let me know. Thanks for all the wisdom.

Sounds like a problem i had when testdriving a (tuned) R33 GTR, just when boost build up it starts to stutter and really dont wanna rev any more, and you dont wanna either!

Turned out to be broken lambda(s).

Hope it gets sorted!

Another possibility is a blocked cat...it has been known to happen...takes 5 mins to check...however my first guess would be a leak in the piping somewhere...

On a side note...you're not the first skyline owner to be humbled by a camry...i know of a 33stst driver from here that got axed by a camry...and then he got a 34gtt and got axed by everything else...following that he got a 33gtr and we're waiting to see what else gets him...

It's not a leak in the turbo piping - the engine is making 3.5 x 100mm Hg boost (approx 7psi).

It WILL NOT be O2 sensors - the ECU ignores them while boost is happening. They may, however, be contributing to the poor fuel economy. But that may also be caused by trying to "drive through" the present problem.

If the car has been fitted with larger aftermarket turbos, it might be suffering compressor surge.

Check ignition timing.

Thanks to all who have contributed and helped me where to look. I have gone over O2 Sensor, AFM's, Turbo's, Intercooler Piping, Clamps, Hoses, No fuel leaks, and it isnt the fuel pump as i checked it with the previous problem.

I thought it might have been a blocked cat but its only 3-4 weeks old and i had the exhaust fixed 2-3 weeks ago, wouldnt he have noticed :-P

-----------------------------------------------------------------------------

PROBLEM FIXED

* Today the O2 sensor was checked to make sure it wasnt broken, cracked, or rattling. The Intercooler piping was checked, all hoses were removed and all clamps checked, these were then replaced after passing the inspection. Removed both AFM's and checked them, sprayed them with Contact Cleaner along with the plugs.

* Reset the ECU and VROOOM, it goes... :-)

-----------------------------------------------------------------------------

One thing left is to see if that fixed the fuel consumption. Will Keep you all updated on this.

Now i wanna see that 60yo pensioner camry driver go me. Before i was in 3rd or 4th gear when it hit 60-70kms. What chance did i have LOL. I just let the old dude think he beat a GTR with his mrs next to him. He needs all the testosteroe cranking through him as much as he could hehehehe

Thanks again to all members of SAU, My R33 GTR Thanks you also...

yeah the old pensioners sure love their track racing..

1995 R33 GTR vs Toyota Camry (60yo Pensioner Driving)

Hmmm, let me tell you the story. It was around a left hand corner, he was leading... After that there was about 200m up the straight away before there was only enough room for one car... and he won... :-P

Play by play, we go through the corner, im in 1st, still going through the left hander, i snap it into 2nd. By this time we're doing 25km/h, my foot goes down and i move quickly to the left as he takes the right on the straight away. I can see the camry blowing some smoke as they floor it. The GTR accelerates to 40km/h and i have shift it into 3rd, my foot goes to the floor and the GTR moves up to 55km/h screaming its head off. I look over at the occupants of the Camry, they're an elderly couple in their 60's. I can see the light, there is an opening as the nose of the skyline is to the rear doors of the Camry, I move it quickly into 4th and stomp on the accelerator, i move up to the front passenger door of the camry with 30metres left by this time im doing about 65km/h. 60 some thing year old looks over and smiles as he suceeds holding position. I have to drop back and fall in line on the right. DAMN, lost to a Camry. Shamed. LOL.

Enjoy!

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.

      Could be correct. Meter might be that far out. Compare against a known 5 ohm 1% resistor.

      @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap.  (edit: I went out and did it right now, the line I had chosen did appear to have no vacuum on it, it used to go to the front of the intake, I've now completely blocked that one off at the bracket that holds several vacuum lines by the firewall.  I T'd into the vacuum line that goes from that bracket to the vacuum pump at the front of the car, but no change in the MAP readings).  Using the new vacuum line that has obvious vacuum on the hose, im still only getting readings between -6.0 and -5.2.  I'm wondering why the ECU was detecting -5.3 when nothing was connected to the MAP nipple and ECU MAP selected as the source. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.

      Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
