You will get over 160 kw it's not much at all. My mate has a vlt standard turbo engine put a gt3040 on it sees 17 pound and makes 270 kw with a bigger pump and injectors stock computer. if your just turboing the na engine can't see it lasting to long see it first hand piston went through the head. Like jez said by a 20 or 25. You can buy a 20 for 700 throw a 2510 or td06 and you will love it jez can tell you about a tyre frying 20

I'm not looking for huge huge power, I was almost happy with my N/A tuning. I think it will last a fair while with 7 - 9psi boost, the motor is in good condition. I have a friend still running more boost on his stock RB30, and I know many many more people who do the same. I don't think I'll see a piston going through the head on 7psi through rb25 turbo.

To get back to your original question going by your plans a stock exhaust manifold will be the best bet for you - in any case a new fuel pump should come higher on the list than a fancy manifold.

Use the stock manifold. When the engine blows put a 25 head on it and then buy an aftermarket manifold. Saves you buying two manifolds.

The ebay spec steam pipe is the same as we bought for the jpp missile r33. It had a pin hole which we welded up

wrecker spec rb25det is making 437 hp at the wheel on 19psi boost.

Nothing wrong with the manifolds as long as you check them well enough for pin holes. As far as long term cant say just yet

Thanks for that mate. Yep I am using the stock manifold now, for all who were reading, I picked up a stock VLT manifold for $142 delivered (won on eBay this morning). Once I get it all up and running I will look for what next, but I still need front coilovers which is higher on the list than big power.

      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

      R34 25GT Engine Light 21

      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.

      Can you mount the ATTESA pump in other locations?

      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!
