I certainly wouldnt bother balancing it, though expecting it to hold together at 500hp ATW is a bit optimistic. Its not going to be much stronger than an r33 rb26.

Looks awesome. a mate built one similar, they are really a bit silly, there is no way they put any power down, it will still be wheelspinning at 140km/h regardless of what gear ratio you put in it. Just be carefull, the shorrt wheelbase means that they are keen to turn around, and at 100km/h they can step out and flip in about .1 second.

You cant get a replacement diaphram?

If you are going to use the gtr pomp(if its a wide drive)Then you really have to fit a crank collar, which adds up to about $400 once fitted. Unless you are going to run a narrow drive r32, then its all good

I wouldnt worry too much about the crank being eaten away by the seal. You could fit speedy sleeves over the surfaces, but they are about $75 each. If its only a track car, its not going to leak that much oil anyway. Just reuse the metal head gasket, using some coppercote spray. I would just get a set of rb25 head bolts or studs if you want to get fancy. Dont even attempt to redrill and tap the head bolt holes yourself.welsh plug is about $2 try an Auto One, but ive found the cheapest place to get seals is a bearing shop like CBC. Oil restristor can be cheaply made from a MIG welding tip. Just buy one with a hole the right size, about $5. What oil pump are you going to run? I would be tempted to use the standard rb30 onw, as they dont seem to fail ?!?

You could always put a z32 sensor into a 4in pipe, that will see 400rwkw(or you can use the stock AFM, ends up at about the same) There is a thread in the fabrication section that shows how to do it neatly.

Dont think so, they are a completely different design. Plus a 25/26 has two of them which would be more effective at picking up knock

I think thats for the 25 sensors, they are located lower in the block then the 26 ones from memory.

I just hope that you are taking into consideration that it may be taking longer to warm up because it is so damn cold at the moment

There are no holes where the rb26 knock sensors are located. I just drilled and tapped the holes, and attached

Doesn't sound like a vacuum leak, it sounds like a boost leak, which wont be picked up by spraying brake cleaner. Pump up the piping with a bung in the AFM

Welcome to MOTEC

Are you running 18psi with stock turbos?

Adjust the actuator, give it a bit more preload, and see what the results are

I would say thet the 0.5% of customers who would be happy to pay the extra for a purged exhaust system, all of them wouldnt want it done in stainless, when inconel or titanium are available.

The opposite of a light switch, it should be a torque monster, making meaningful boost and torque from 2500. Full boost of about 16 psi should be in by below 3500.

These are internal gate turbos

Im building a 30/25 neo at the moment, will be running .86 gt3076, i think it will be the ultimate street setup. No lag with over 300rwkw within easy reach

Is it the first PFC he has tuned? All the hand controllers are in japanese in some of the screens

Im not, two different motors, the 10,2's are in the 30/26. The 30/25 neo has a stock gtr inlet can, and a tomei exhaust cam(9.2mm 256deg if i recall)

Or a 32gts-t that already has an rb26 in it, there waws one on ebay recently that had a reserve of $9000

To be perfectly honest, i dont see purge welding as being necessary on a car, especially not the exhaust. How much power gain would you expect to see if an exhaust is purge welded as opposed to mig welded. The weld wont be particularly stronger, and it really makes no difference as the exhaust strength isnt crucial. Ive never seen a "custom" exhaust from a shop where a stick welder has been used. I just cant see the market for a purged exhaust.

Just clean them off woth some petrol, degreaser or carby cleaner, they look fine

It was sea freight, took 5 weeks. It was based on weight alone, as the chargeable weight dimensions for 140kg was over 1 cubic meter, therefore the same motor weighing 50kg would have been heaps cheaper. Put it this way, if it had been a140kg block of steel, it would have cost the same

Looks good trent, what do you think is causing the fluctuation of the torque, on the higher boost run, is the boost stable?
