laggy with the t51r? how much power are you making at 100kmph/4000rpm?

ive also had a massive headache with controlling boost. went from a 38mm gate to a 33 and then eventually to a 60mm gate ive currently got. took a good few months to sort that out =[

My dyno sheet doesnt start till about 4500 from the auto and we had to ease the throttle on in the midrange as it was wheel spinning.

As for power at 100kph, cruising in top gear at 100 and stand on the throttle it would just light up the 18s

All I did was have 1 fitting installed on the intercooler hot pipe if you dont already have one, then had a dyno run with the boost signal coming from the hot pipe. Then Trent plotted both the plenum boost and the hot pipe boost and you can see how the difference gets wider as rpm increases. Therefore, I would get a good result out of a better intercooler with less pressure drop (ignore the std turbo graph).

My mech says that the vavles have to be taken out a actually tested. With all that effort I decided to just buy brand new ones. Will have it fited in a week.

Managed to also back pressure test the exhaust. Less then 1psi all the way to redline.

Still have yet to test the cooler, will be sorted out soon.

Valves out to test?

Did you check the manifold pressure or the exhaust pressure? and what exhaust manifold are you using?

Notcied you said you were having heaps of boost control issues? manifold might be doing funky shit to the exhasust gasses at the collector

Was this under load? If not, it doesnt mean much. Without load the cat would have to be very blocked for it show up as a restriction. There was another thread about a car that was tested by free revving to have less than 1psi to redline and the cat still ended up being a restriction (ie more than 20-30rwkw).

The run was under load. I'm not running a cat and it's a 3.5 straight pipe exhaust system. I highly doubted it was the exhaust but got it out the way.

I seem to also be having cas problems. Symptoms recently included alot of misfiring on cruise and running rich. This wasn't a issue when we had the car fully tuned months ago but is halting our progress until resolved.

Of anyone can help me out it's a r33 rb26. Which CASs are interchangeable?

This sounds familiar, did I meet you at Status last wed?

    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
