No offence but that looks hideous and it's ability to flow well would be questionable.

In fact it came of an RB25DET pushing around 500rwhp

I couldnt give a shit what it looks like as long as it does its intended job.

Please justify 'questionable'?

Hi Troy, I have this conversation with many customers and we have tested both back to back to determine the pros and cons. The main difference is that the Plazmaman retains the standard runners, wher

God those throttles are gorgeous, gotta get around to getting one, would finish mine off nicely me thinks. I see that they have slighlty changed the plenum with "Plazmaman" not being engraved on the t

Lol no need to get pissed off about it, just said it looks terrible. It's not like you made it and im saying your work is shit.

Whether it made 500HP is irrelevant, you can do that on the stock plenum (for reference the Plazmaman one is rated at 1000HP worth of flow, in other words its "horsepower flow" is irrelavant.)

Its just a stock plenum that has been cut up and made into a foward facing plenum (as many people do) but he has changed the centre of it completely, however do you think it has been created to flow well and R&D put into it to flow as evenly as possible like a Plazmaman or Greddy one would? Just saying. It may flow well, it may not, hence my "questionable" comment.

All good mate no offence taken and I’m not shitty lol.

I understand everyone is entitled to their opinions however, it might pay to keep 'possibly' offensive comments to yourself. If I 'had' made it myself would you have made the same comment? Food for thought.

What I meant by "pushing around 500rwhp" is that the guy I bought it from obviously had no problems with it flowing well.

I love the pics of your engine bay and most of the way you have gone about your build but there are certain things I would have done differently. But I’m not about to start criticizing you for this.

It’s these differences that make owner/building and modifying such a personal thing and it’s what keeps forums and discussions such as these happening.

I chose to use this modified forward facing plenum as I am building/modifying on a very tight budget and cannot afford some of the more exotic items on the market. I have researched the factory modified forward facing plenum and it suits my intended build and purpose just fine especially from a budget conscious point-of-view.

I did not intend to compare my plenum to either the plazmaman or the greddy.

I was actually looking for info in regard to the benefits of using a much larger than standard throttle.

Any way back to the question.

I'm worried about the affects of turbulence as a result of interrupting laminar flow, So can anyone please tell me what the pro's and/or con's are of changing to a larger than standard throttle body?

Fair enough man. And no I would have not made the comment if you said you made it as I would not have wanted to offend your work, but since you said it was off ebay, hence I made the comment as I didn't think it mattered. All good.

do u need a retune once the plenum has been installed?

I did. I'm not sure if it's necessary ,but i went fom a return flow cooler with original plenum to a standard front mount with a forward facing plenum and i gained 13 rwhp up top.Made more power down low until 4100rpm.Then made less power until 5100rpm.After that it just pulled better nicely til 7200rpm where as before that it stopped rising in power at about 6700rpm.

Hey guys, I've got the Plasmaman plenum on my r33, came with the car when I bought it. Just took it for a dyno tune and my tuner said he doesn't like the Plasmaman plenums as they don't distribute air evenly to all cylinders. He then proceeded to show me the different colours of the plugs.

Anyone else come across this before regarding the Plasmaman plenum?

      I suppose that's true. Barring almost any situation, I'll never sell so what the market does is kind of irrelevant to me. It's possible I'd make most of my money back. That spreadsheet I mentioned? Maybe I could make back more than what the car's total costs thus far are, but the parts and all that is possibly a different story... Thanks for reading. It was certainly a good moment and just makes the ties to the car that much stronger. It's exciting that the option will be there to bring it over, however I have some plans with a shop that may end up keeping the car there longer, not sure. Coupled with the fact I want to move there and haven't solidified any path yet. So in a way, it feels like I'm in a limbo state that is uncertain; time will tell.

      No worries, everything worked out in the end. I just wanted to make the point that it doesn't matter where it comes from (I.E Australia), it can be broken or improperly built. I would still purchase from these companies in the future. B2R - Not certain how that finished, this was on a car I wired a few things and street tuned. I know the owner ended up shipping the motor back to Australia for investigation. Hopefully some of it is covered under warranty.  Turbosmart - I always pressure test everything that goes on my car. It's a habit from my career in oil and gas. I run two 40mm's and both had major leaks from the actuator to exhaust portion through the shaft. I returned both, they shipped me back two and one was leaking and the other had a 38mm top (40mm gate with 38mm actuator cap, no idea how that happens). Eventually after a lot of back and forth I found myself with two non-leaking gates. I believe this happens a lot more then people would like to believe but you would never know if you don't pressure test them prior to installation. Crank Motorsport - Issued a full refund and let me keep the seat rails. I turned them into scrap metal for other projects. GKTech - Shipped me out a replacement and asked that I modify it as per my idea and that they would do the same for a future revision. ATP - Can just needed a large shim to bolt up properly.  Haltech - They started an actual proper Beta channel for firmware's a few months back and stopped using the general public for testing. I'm now much happier.  Speedtek - f**k Speedtek. I would love to watch them burn.

      I've got a Turbosmart wastegate, ATP catch can, many GK Tech parts and Haltech everything. Everything's been perfect, sorry to hear your experience wasn't the same
