Hey all,

Have spent the best part of 6 hours scouring not just this forum but the whole interwebz for information but just can't find any concrete answers. If there is a thread containing this information already, please abuse me and send me on my way action-smiley-069.gif

So basically I am interested in getting a Plazmaman plenum for my 34, but would like to have a few questions answered first. Preferably with first hand experience, as I've found plenty of people who's brothers mates cousin has a friend yada yada... The biggest issue for me is the fuel system. Will this plenum fit onto my car with the standard top feed fuel rail? I'm using Power Enterprise 660cc injectors at the moment, which are a fair bit bigger than the factory items as well... If it will NOT fit, what are my options? Is it simply because of the rail, is it the injectors, do I need to switch completely and get side feed injectors on an aftermarket rail, etc??

What else needs to be done to fit this? From what I can see, the washer bottle is gonna have to be relocated so that the fuse box can move over to make way for the throttle body.

Any help will be VERY much appreciated, as pretty as the Plazmaman plenum is, I'm getting rather sick of looking at them in R33's... :P

Thanks a lot,

Martin.

We've fit one before.

The stock fuel rail is fine, as you said washer bottle and fuse box are in the way.

Stock throttle body needs to go along with the traction control gear. From memory we used an R33 throttle body.

Dahtone you're a life saver! Thanks mate.

Washer bottle relocation should be easy enough, but where do most people put theirs? I'll probably just get a smaller universal washer bottle and see where it can go. I've got no problem with ditching the traction control as I've done that already :P I will just spend the few hundred extra on the Plazmaman throttle body as well, might as well go all out if I'm spending this much money cleaning up the engine bay.

What about the fuel pressure reg, I notice in your above picture that the car has an aftermarket fuel pressure reg fitted. Will stock get in the way at all? In this picture (stolen from 34GeeTeeTee's build thread thumbsup.gif ) it looks like it is going to be in the way:

As well as this build thread I found on Skylineowners.com:

P10006681.jpg?1328406969

P10006621.jpg?1328407040274

Both these guys solved it by changing their fuel system completely, but am I safe to assume that these things can simply be moved out of the way or?

Ah ok that's easy then. So you just swapped them around as simple as that, or you ditched the dampener? Thanks again mate, have made this a whole lot easier for me haha.

Another question, has anyone used the Plazmaman piping to the IC? Where is it routed, through the top of the battery tray requiring a new hole or can it go back through the side and underneath like my current FMIC piping goes?

*EDIT* Oh yeh, what about the throttle cable Dahtone? Did the stock on fit as Plazmaman claim or did you need to make one up? I'm also assuming the TPS wiring will need to be extended which shouldn't be a big deal?

Edited by Hanaldo

Does removing the dampener not cause problems? Am I best to get an aftermarket FPR with a built in dampener if I am ditching the stock one or will it not make a difference without it?

There's 12 posts in this thread, half of them talking about whether the stock fuel system will work. If you're not gonna read those 12 posts, can you at least wait until I post the how-to thread so you can just look at the pretty pictures to see how it works out?

Right, so after a few back and forth emails with the Plazmaman sales team, I'm highly doubting they are going to be any help to me. I asked (before Dahtone replied here) whether the stock top feed fuel rail is going to be a problem, they said no not at all. So I said I've got Power Enterprise 660cc injectors which are about 70mm compared to the stock GTT's 60(ish)mm, so the fuel rail has been spaced about that much, will that be a problem. They responded by asking what brand injectors I am using blink.gif They also said they have attached an image of an R34 using the stock fuel rail, but the attached image was clearly an R33 using an aftermarket fuel rail glare.gif They now want to sell me a fuel rail they are making for the Neo. Of course.

So I think I'm just going to go ahead and purchase the plenum and throttle body, and see how far I can get with what I've got. If it turns out things need to be changed then I'll cross that bridge when I come to it. I can see this plenum install having my car sitting in the shed for weeks, so it's going to have to wait 2 weeks or so until I get my daily back. I'll try my best to document the whole process for anyone else here wanting the same answers as me.

    • The real question is, on some of those wild roads they call highways, how many times did a farmer in an old ute from the early 2000s blaze past you over double lines?   Tassie is a wild and really cool place, and after doing a work related road trip there January of 24, I understand why Targa Tasmania is ran there, and is so tough to do well at! We had a brand new Camry Hybrid that handled quite nicely, and thankfully weren't in an old car, because cresting some of those hills in a 100kmh zone for it to suddenly be like "surprise f**kers, this is a recommended 30kmh hard right turn" wouldn't be pretty. We weren't racing the Camry around, but we weren't slouching in the bends either. But my lord those old farmers know their old clapped out utes, and those roads, as they were absolutely hammering it!   You're also super lucky to make it up to Mt Wellingtong this time of year. It's often road closed with snow/ice! Also, I hope you hit up Salamander Road in Hobart for some insanely good food (I highly recommend the dimly lit Irish pub for a Guiness Pie, or even the bangers and mash!!!)   How long did the Ferry take to get across? I want to do a road trip of Tas on my own time, but I get horrifically sea sick, and I don't want me on the Ferry, just the car 😛
    • So far so good, about 30km on it so far and nothing out of sorts yet thankfully
    • Look at @Kinkstaah's thread on the issue.
    • Hmm not really, I'd say its race car life or modified car life when you make 3 or 4 times the power Nissan designed the car for lol. 
    • I'll let others with more breakage chime in, but I can't think of anyone who had a problem with the standard centre plate before they had a problem with the standard gears - the plate generally just gets replaced for safety when the gearset is upgraded. As for the gearsets, its not like they are OK at 600Nm and break at 601. Their longevity is a combination of how much torque you are making and how gentle you are on shifts (or not).
