If doing a DBW with ecu/loom can now do it on factory plenum

Yes, I currently have a modified factory plenum with single throttle DBW

Then just keep the factory plenum :) 

No need to burn more money on a fancy Plazmaman plenum for little gain (if any). It does look good though, billet dis dat albeit for a Rb25 shit box.

Yep, my mechanic said, little to no gain in performance, all for aesthetics, problem is, with as far as I’m now going with the car, should I skimp out on this??? 
my personal opinion is, I love the Nismo plenum, but to buy one and cut it up seems…questionable. 

If you're going to change it, at least go a Plazmaman or CPC not a Nismo one. Nismo "performance" parts don't really perform if you know what I mean.

(This is my personal opinion 🙂)

maybe a little…😆

The Nismo plenum only makes sense if you want a few key design elements like the longest intake runners you can fit in a factory ITB setup and the different intake runner designs to avoid leaning out cylinder 6 to some extent. A single plenum design like the Nismo as far as I can tell will never actually work perfectly at equalizing airflow between cylinders. Dollar for dollar it is a horrible upgrade IMO but I have weird priorities. HKS is working on a dual plenum design that may be more what you're looking for and will be single DBW throttle body.

He's still using the factory ITB, you're planning on chopping it to fit a single DBW TB which will affect the way air flows and distributes across the runners at partial throttle.

Something I haven’t considered, I am leaning towards getting the Plazmaman plenum.

In my quest to catch up to R32 25T, things are moving forward, more parts back from cerakote. Hoping to order the gearbox next week. 

All your cerakoted parts look great and it seems to suit a wide range of parts. I was thinking of having front and rear hoon bars, miscellaneous brackets, Apexi pod elbows, battery retainer bar and the ugly retainer that the throttle cable passes through done.

Do you think anything on that list isn’t suitable? I googled this for at least 60 seconds but most of the articles were about how it would improve the longevity of the assault rifle that I don't own.

That is all suitable, They can even do plastic parts, he showed me a fuse box cover from a VL he did, looked brand new. I’ve given him a few plastic parts, I’ll post them when I get them back.

  • 2 weeks later...

More parts ordered, more parts coming in, Nismo restoration! Pfft, got nothing on me. Lmao 

Also got brand new headlights. 

Had the engine bay ceramic coated by my Detailer while it’s bare, came up a treat.

Full resto!

That engine bay is going to look amazing once all back together.  Are you doing anything funky like wire tucking, brake line redirection or anything else?

I’m getting Pro wire to do a custom engine loom to incorporate all the extra sensors, DBW etc, still haven’t decided weather I’ll delete the fuse box and run everything off a PDM. I want to change ECU to the Motec M150, just got to talk to a couple of people to see what my options are. 
I’m moving away from the factory plenum and will be running the Plazmaman. I’ve finally decided on gearbox and will be running a 6 speed getrag box. 
also contemplating changing turbo, I’ve bought a 68/75 turbo which has the .81 T4 open rear (I believe) 

considering changing to the Garrett G40 1150 using the .95 T4 divided rear . 
manifold I’m using is a 6 boost T4 divided

Getting serious!  Will be an absolute weapon!

Hoping for a nice reliable street car, but am going overboard in some areas,  and I do know that, but… GTR life! Lol 

Well as my plans on set up change more then my underwear I’ve decided to strengthen up the bottom end of the motor while it’s out of the car. 
will be installing a PRP brace with billet main caps and 1/2 inch main studs.

will make final decision tomorrow, but will probably get the 7675 sportsman with 1.12 T4 divided rear with a proper divided manifold. 
At this stage I’m thinking (and this will probably change 10 times before the car is done) but will run the getrag for a couple of years and enjoy the car for street duties, then I’ll just bite the bullet and put either an Albins or Samsonas in it and do the track stuff. 
I’ve spoken to a couple of people I know who are running similar turbos, (both have 2.7, one running 7675, other 7685) and both say it’s not as laggy as you’d think, but crazy fast when it’s on. 🤔

    • 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.
