Ok, Heres my problem.

Today (Boxing Day) I started my car and took off fairly hard bringing first gear up to about 6000, I then proceeded to change to 2nd hoping for that nice wheel spin can be achieved from this. Alas I was not greeted with wheel spin but a great loss of power like bad turbo lag instead.

Now to my problem, ever since this every time I get the revs to 3000 in any gear from 2nd up, the revs suddenly jump to 4500 and then back to 3000.

There is no jolt when this happens, just an over revving laggy engine.

Also there is now a slight ticking noise coming from under the left hand side of the bonnet when the car is idling.

I am thinking that it could possibly be a blown turbo gasket? But it has all happened so suddenly after me being stupid and not allowing my car to warm up correctly.

Could this be the cause, What are everyones thoughts?

BTW my car is stock except a 3in cat back.

Any help is greatly appreciated as I am fairly new to the world of turbo cars, and my mechanical knowledge of cars in general isn't exactly in depth, so go easy on a newby

Ticking sound from the around the turbo certainly sounds like a blown turbo gasket, I had similar problem a while back.

If it is, its not an expensive fix.

Poke your head in the pasenger side of the engine, you may be able to see the problem.

Dont go flogging it, cause if its the gasket you dont want more pieces of the gasket breaking off and flowing through the various parts of your engine.

Thanks mate. What exactly am i looking for with a blown gasket. As I said I am a complete newby to the world of turbos, but I am doing my best to learn about them.

I know where the turbo is located but what exactly would the blown gasket look like?

Any help is greatly appreciated, as none of the mechanics in my area that I would trust to work on my car are open due to the holidays.

Thanks in advance.

Sounds like it could be a slipping clutch to me?

Trying to decipher your problem as a couple of the other guys have stated it does sound like it could be your cluth that is the problem.

But just to clarify something for you you say it feels like and over-revving LAGGY engine

Over-revving does indicate slipping clutch ( you can check this by loading the engine in a higher gear at relatively lower speeds) caution though be careful not to do to much damage

Lag is the lack of REV's or "pick up" when you accelerate theoritically opposite ends of the spectrum.

but anyway good luck.

thanks for all the replies everybody (and for the definition of laggy).

Sorry for the late reply computer problems, it never ends!

As it turns out the clutch was the problem, took it to autosport and they had it diagnosed about 2 seconds after getting into the car.

Anyway, it is now replaced with a heavy duty item and is going better than when I first bought it. It is even creating up to 10 psi boost (only could get 7 before new clutch).

So in summary thanks for the help, and these forums have now become my official home away from home. Such a wealth of valuable information!

cheers

      Rb25det s1 igniter pin out

      By GTSBoy · Posted

      It's definitely not firing order. But I think it should also be made clear that the output that gets fired is the one that corresponds to the input that was switched at the ECU. So you could scramble them up totally so that the numbers meant nothing, and so long as you had the inputs and outputs matched up, you'd be fine. The reason I make that point is that blanket statements about what it is supposed to be don't always hold out in a world where there's been 30 years for the wiring to have been stuffed with.

      Rb25det s1 igniter pin out

      By EndZee · Posted

      Hello, im asking about this guy - coil igniter on rb25det series 1 r33 s1 engine. I need to know if pins on coil side indicate coils itself from 1-6 or it’s firing order so pin nr1 goes to 1st fired spark plug:(1pin-1firing spark, 2pin-5order firing spark, 3-3, 4-6, 5-2, 6-4…)   photo: https://files.fm/f/k9pdug38uq

      Powder coat on mating surface

      By GTSBoy · Posted

      Remove it. Certainly from the hub face. I'm not in love with leaving it on the wheel assembly surface either - but if it is common to do so, then....maybe fair enough. It's not difficult. Just time consuming. For the hub face you just need a large enough block and suitable grades of abrasive paper to get it off flat. The same would be true of the assembly face. Just more time consuming, probably needing a lot more care. It's defo going to be easier just to assemble the wheels as is, seal them up, and check them periodically to see if there's any movement or loosening of the fasteners, than it will be to remove it though.

      Powder coat on mating surface

      By dyl33 · Posted

      Hello, I got my wheels powder coated and they've powder coated bloody everything the mating surface and hub (even told them not to lol) anyway should I leave it or remove it. (Would be very hard) I've searched a lot and lots of powder coaters don't mask the mating surface but do mask the hub surface. How bad it powder coat on the mating surface or hub? My question is what should I do?

      R34 Gt Auto Tuning

      By dbm7 · Posted

      Yeah, R34 with RB25DE likely has a 4AX01 box in it, which is a medium duty auto ~ with the RB25DET mill, it would've been fitted with 4AX00 (4AX13) heavy duty build (same case, different internals). An RB25DET will lunch on a medium duty 4R01 auto in pretty short order ...to give you some visual idea of differences between the 'medium' and 'heavy duty' boxes, you only have to look at the 2/4 band for comparison...it's chalk and cheese...(plus bigger high clutch, extra pinion in the planetary sets, higher oil pump output, different bearings, higher TC stall speed )... You can control them with just about any aftermarket TCU for electric-over 4-speed with TC lockup clutch (ie; the GM 4L60E and others)...I have a custom standalone TCU that includes MAP sensor (for turbo applications) along with TPS, RPM, and line pressure monitoring...in other words, I don't use any ECU signals...no real need to.
