hey People

Was wondering how much power can a HKS Cast Split Pulse Exhaust Manifold can hold and how much punishment can it withstand......

Also is there Advantages for this over a High mount manifold

thank you in advance

I've been running one for a few years. What do you mean by abuse? Mine has been heat wrapped most of the time, and I've been making over 400rwhp for like 2 years. 500rwhp for about a year. The are beefy as anything out there and I couldn't see how it would be possible to crack one.

The only advantage I can think of for the bottom mount is that it's a straighter shot for the exhuast. It doesn't have to make those 2 near 90 degree bends. I don't think it's much of a benefit though.

400rwhp... that is cool..... i just like the look of these manifolds

They look very simlar to the standard manifold except with a flange for the wastegate.

I have seen a couple that have cracked one the forum

Im using the rb26 version, which is basically the same only larger. Mine is ceranic coated. the benefits over a stainless tubular one is improved heat(energy) retention, far more resilient to cracking. They usually only crack inside the meerger, which almost all cast manifolds do, and doesn't cause leaking. Having said that, most of the stainless ones cracking IMO is caused by poor installations where there isnt enough bracing, and the manifold is taking the weight of the turbo and exhaust, which wants to flap around.

      Actually,  just remembered there should be info in the threads (somewhere) about swapping to a manual steering rack and deleting power steering all together.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open

      Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.

      I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂

      Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy
