So iv disconnected my stupid factory dual stage boost controller on my r 34 and fitted a tee for now just to get a few more psi from the factory turbo before I put all my bigger stuff on , problem I'm having is its just a dog down low it feels like it's not barley making any boost and is really sluggish through the bottom end of the rev range ! Iv taken the boost solenoid off near the power steering res and taken the other part of the top of the rocker covers near the firewall and I'm running actuator to tee then straight into hot pipe off the turbo , any suggestions on how to get it running right or is this just how shit neo motors are iv owned 3 rb25's non neo prior to this and never had a problem they all rev freely and the boost is easy to tap into this thing is slow as

Hahaha.

Neo engines aren't shit just cos you can't figure out boost control.

Anyways, running more boost on an untuned ecu is pointless, just wait until you can afford to do things properly with a tune.

What part near the rocker cover on the firewall?

The map sensor?

There's your problem

lol....I would be re-mounting your MAP sensor..

if I were you I wouldn't even remove the stock solenoid. Cut the tubing and terminate the tubing with screws or plugs. Then install your boost tee hidden away.

That way if your engine bay ever gets looked over by the popo or RTA you look like you running standard boost with no controller…

Iv got a haltech ecu , 3076, 1000cc inj 40 mil gate all the shit off my track car waiting to go on but that's not going to happen over night , just looking for 10 psi to have a bit of fun till I deside to do all that , the only thing iv taken off are for what I thought was the dual stage let me know if I need to put any of this back on , car runs and drives fine just a slug down lowpost-76499-13970979536854_thumb.jpg these are the only things iv removed

Yeah forget about the other stuff at this stage as iv said I'm not putting that on yet , so is the boost sensor or map sensor as your calling it can I ask why It needs to be put back on ? Doesn't it only send signal to the ecu for over boosting or does it serve a larger purpose ?

Everyone here is trying to provide help…

I suggest you mount the stock solenoid back in where it was and plug it in… then joing the boost lines up like they were from factory. Then cut those lines and plumb off the ends and leave the solenoid plugged in.

Now add your boost Tee inline and see if you have fixed your issue.

Personally if I had all those good bits sitting aside you had I wouldn’t be messing and putting undue stress on your engine/turbo.. I would wait and fit all your goodies then play

Just my 2c….

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • 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.
