runners on greddy arn't as good as plazmaman runners. Ive driven a car with greddy plenum and one with just stockk and i'd say stock was better with way more pickup. I found greddy to be a little restrictive. The greddy ones look heaps good but im yet to be impressed by their functionability.

Any one else have any details on when the neo version will be out. Hopefully they dont take as long as the 33 version.

the reason you found this i was told by plazmaman was , Greddy has its own runners. where as Plazmaman retains stock runners. and just bolts up to them. the smaller runners give more torque with that plenum. creating more response :)

sorry but your argument is baseless.

i cant believe someone wrote this.. sorry i think u should do a little bit more research regarding runner and there length ...that is way off base that remark..

so your saying the shorter the runner the more response so there is less overall volume to pass through....?

cheers

I think thats what he's sayin but im not sure how valid it is. Does someone with a bit of plenum knowledge wanna tell us what they think about silverbullets explanation for increased response...

im not a fan of the plazmaman plenums, dont get me wrong they are built great, but iv seen a few people now having cooling issues.

Like Pauline Hanson says ' PLEASE EXPLAIN' - what the hell does a plenum have to do with cooling engine water ??? Owners fault - More than likely the engine water system was not bled properly and air pockets are in the back of the head , this blow head gaskets . UAS installed my mates (R33 ) and it had no problems .

Apparently some curcuit cars at UAS running the cheap intercoolers all cooked on curcuit days . They did not let air through to radiator properly . This could be those peoples problem .

i havnt had the experience personally, but a mate of mine has and 2 others that got it done at the same workshop. apparently when it goes on it creates a air pocket that can not be bleed out? (even when fully pressurised) unless you change some of the cooling piping. maybe cause all 3 people had the same problem (all a rb25) from the same workshop it was the workshops fault? tad over priced to!!

Never heard of a cooling system that could not be bled out , add a bleeder hose , its common sense . Costs about $1 and a clamp . Maybe its the workshops fault . They probably are not good engineers . Try CRD , they are real good at fitting stuff and know what they are doing .

I think they are a bit dear too , cant afford it yet , but at UAS dyno day recently the 2 top power cars had Plazmaman plenums .

Anyone know where to get the GReddy copy plenums from... or the Plazmaman (sounds like a character from that movie orgasmo) Please PM me as i wouldnt mind trying one out.

unique autosports in seven hills are the best place to goto for plazmaman products as they test them on the side for . plazmaman so they know a shit load about em. I would think most places selll greddy copy's, maybe crd

first of all besides the bling factor most people on this forum reckon u should change the plenum at 300rwkw but i disagree with this on the neo there is more to be had if changed earlier!

ok then ive got a greddy plenum on the neo ..now normally u would upgrade the plenum with a much bigger turbo so i also have a much bigger turbo on the car ..

ive recently made an adapter plate to make the runners longer on the greddy plenum and have recieved a 20% gain on midrange and top end just by simply making the runners longer.. meaning 20% = 20kw difference also the other difference was response all i can say is holy crap !!! its much more responsive ive got full boost between 3500-3700 all the way to 8500-9rpm.. i was very surprised!

when the adaptor plate was not in i was getting full boost by 4000-4500rpm.

so i would like to know what plazmaman is telling silverbulletR33 about this runner crap .....?

cheers

Im no expert did i forget to mention that? My Wording may not be 100% correct either, it could be caused by port Design Not just shorter lenght , But Im quite sure thats wat the guys down at Plazmaman was telling me that, Simply ..he said when using their plenum with the standard runners it created more initial response and more torque.

We chatted for a while about that and why, so They sent me across some Dyno sheets to check out, As I'm planning on buying one very soon. Who knows Sales people say anything to get a sale but these guys are well known for good product so i believe them, . I did not get to talk to the Owner though as he was busy, so maybe you should give them a call if your interested about why this is so? and have a chat with them :/.

cheers.

realistically if i was going for bigger numbers i would not choose the plazma cause it retains standard runners. I would go the greddy over it. and i would imagine. It would flow more thru them over the Standard runners and probably have alot better flow rate/swirl ie. port design. But my setup is for Response and balance and power combined. hense my choice.

and yes i was wrong to say smaller. For the same reason as what happens when u put a tunnel ram on a v8

*edit and i shouldve said int he first post, that i know of only the rb25 had the standard runners. they do make complete plenums also.

What i shouldve said was STock insted of smaller. I see ur point. And i just checked out my standard runners, and it looks like the greddy ones are actually shorter than the stock ones. I havnt got a greddy one here to measure though.

What size turbo are you using? thats exactly where I want to hit full boost 3500.

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
