Some of you know that I am putting a gt3582r on top of a 6boost manifold in my r33gtst. I have a z32 afm. Where have you put yours? I was thinking near the start of the "J" pipe. I have done some reading about it and I'm after first hand experiences on what psi it has burst at. Does wrapping it help? The manifold will be here early next week so I want to start getting it ready this weekend. Any other tips appreciated in regard to afm in cooler piping.

I have mine post cooler- pre tb in the straightest part of the pipe. There realy needs to be 200mm from the element to the tb and a fairly straight inlet into the afm.

I've been told by some very experienced guys to cut a hole in the existing pipe work, remove the electronics and sensor from the z32 housing and epoxy it in place.

I'm running a t67 and around 300rwkw with no issues at all.... infact, less issues. I've had the boost around 2 bar so far.

make an intake pipe with a bend and put the afm pre turbo. aslong as theres a bend between the afm and turbo it'll work as per factory

Sounds good in theory but the turbo has a 4 inch inlet and restricting this in any way affects the spool of the turbo. I thought the same thing as you until I looked into it.

myth. a 3" afm is not going to affect your spool

I know we were debating this in another thread a couple of months ago. I believed that because the actual hole in the front of the turbo is only about 2.5 inches (that's the technical way of saying it) that a 3 inch afm in front of it wouldn't matter. I cant for the life of me remember where I read it, and it wasn't Harey's comments, but it convinced me that it is better to run a filter straight from a pipe to the turbo and put the afm in the cooler piping. It will be easier to set up, putting the afm in front of the turbo. I'll try and find the link where it mentions it's not good to have the afm in front.

had a single z32 on a twin turbo so i stuck it in the hot side cooler piping, just extended the wiring down. Ran like that for a year and was great as you could do whatever you wanted on the turbo side as far as pulling things apart/changing intakes and it would still fire up halfway through to move around with 0 issues.

I do suspect it was leaking a little bit on 1.4 bar as every now and then i would push the sealing square cover thing back in on its rubber

Ok so I got the 6boost manifold today and trial fitted it on the car with the turbo, wg and lines hooked up. As it turns out there is no room for the standard "J" pipe any more. I dont really want to cut it but I think it will fit if I do. I can then use all the standard vac lines to the carbon canister and bov. Also the intercooler pipe that comes across the fan wont fit either. But its all good tho. Tomorrow I'll invest in some silicone bends and a hacksaw to modify some of the piping that was on the car and some stuff in the shed. I will try the afm in front of the turbo for now and see how that goes. That way I can get away with using the existing air filter and afm wiring for now.

Got mine in hot side intercooler piping (+ve pressure) - gotta make sure it doesnt leak and silicon/epoxy it up. Advantages are as has been said - can drive the car with no intercooler piping and it will be fine up until boost obviously, really smooth all round, no recirc issues like stalling with a bigger turbo when clutching in etc and not infront of turbo so not a restriction with a 4" intake.

Soz about crappy pics

Had to relocate bov as well as if it is before the afm there will be real issues with recirc and stalling etc

    • 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.
