Justin, yeh I think they probably are meant to go into the cabin. However I wouldnt have any room to mount them all inside without it looking silly or taking up a fair chunk of room. So left it out in the engine bay. Hopefully they wont get too wet there as they are not exactly water tight lol.

Didnt work Justin.

I'm planning to run mine into the glove box or up behind the dash.. Apparently they are fairly sensitive to water and rough conditions... If you do go Vipec, they are compatable and plug right up. Do your thermocouples penitrate into the gas flow or just in the bung welded on the outside or each runner? I keep getting different advice-

PM again.

Ok. Busy day yesterday finishing it all off. Took it for a drive and it ran like shit, as expected. Some further playing in the datalogit with the injector settings smoothed that out. Still doesnt like coming onto boost so early. My guess the fuel map isnt too good for the 0.5-0.8bar of boost it makes as soon as you stomp the gas. The overboost valve is working, hence the low boost.

Ok the catch can does have some baffling inside of it. But it appears to breathing fine. Guess ill find out on the dyno when it counts.

The electric power steering pump isnt setup yet. Its last on the list of things to do. I Will mount it and hook it up once everything else is sorted and working fine.

Interesting you say that justin, cause a few times ive seen mine read some funny temps, maybe engine noise/vibration is causing this... But the actual sensor ends of mine protrude into the runners, so they have gas flow running past them. Well I may have to re run them back into the cab somewhere if it keeps up. Goddamit!

Ok so the good news is there is a video I did yesterday afternoon. It just shows it running. Its not that good and it has me coughing and speaking in it a few times. My apologies.

ok so i just dropped the belt and took it for a drive and it was fine in na form. so it seems its just the tune thats making it hesitate when it tries to boost. i was worried it was a mechanical issue with the setup.

So there was a blow out from the discharge port. The aviation goop I used (loctite 3J) wasnt strong enough to keep the two faces sealed even though they are machined. Dont know what RA it would have been. But I know I had to re-mill the face of the outlet pipe flange after welding as it bowed a little. I would have thought with the 3J it would have been good enough, guess not. I refitted both the outlet pipe and bypass valve and regooped them up with some threebond. Hasnt fully cured yet, but did a quick 6500rpm stab and it made 1 bar of boost and it seems to be holding perfectly. No signs of leakage from around the flange face. :(

Now the overboost valve was fully open and screaming when I did that and it still managed to push 1 bar of boost upto the plenum. Starting to think it might not be big enough. But hopefully once its tuned it would be needed to control boost. It also is stupidly loud when its venting. Other issue is when you let the throttle off sharply, the pressurised air goes out the bypass valve and I think goes out the intake and through the afm...bringing back the unstable idle issue for a second as the revs stabilise. I may need to fit a BOV.... :rofl: I was hoping to avoid having one. Another thing Ill have to see if necessary after dyno tuning.

Man that thing is wicked! 1 BAR free revving, haha must be hitting load points its never even been close to before.

It'll be interesting to see what its like after the tune :P

Got to get me one of those twin screws.

Cheers Simon! Im sure you will see it. It will have to be one of those days when there arent any cops to be seen for miles!

Yeh the 1 bar is pretty crazy. Im not sure what boost its even going to make when its fully on song with the overboost valve locked up. Hopefully nothing too stupid like 30+psi. Well tonight we re did the egt modules and put them inside the car, in the glove box to be specific. It was a shit load of mucking around to get them in there, but its done and working. Which im happy with, though I must admit, sparkies must be just brimming with patience, because it took forever and it was a carnt! I cannot stand wiring. Anyway, its all done now, just needs to be tidied up after the ecu goes back in behind the kick panel.

So hopefully tomorrow nothing goes wrong and it all just does what its supposed to do :D

I just read through all 11 pages of this build r33 racer...fantastic to say the least.

Good to see someone tackling something different & should yield some very good results once tuned !...post tune results asap. :)

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
