Ok yeh i know some of you will get your hate on, Saying "its a soccer mum's car" and "you cant polish a turd" etc...

but i couldn't care less. its my pride and joy.

Im about 70% done. I've got all the parts ready to go on, just need to wait a few weeks till my parents go away and i can have the car off the road (so ive got another car to use while im working on it) Im hoping for low 14s and anywhere from 230-260whp. the reason for the ballpark figure, the only other x-trail thats bin dynoed that i know of, was an automatic with a full engineered zorst, intake and haltech engine computer (it dynoed exactly 100fwkw). to be honest, ive got no idea how itll dyno, cos i know that this 4wd system eats a shitload of power, and im planning to run it in front wheel drive with the rear prop shaft disconnected, cos i've heard horror stories regarding f**ked rear diffs cos of the electonic nature of the 4wd system. that with my car being manual and turbo, i think theres gonna be a big difference to the 100fwkw mentioned.

Ill update as things get done...

Take care guys.

sorry i dont follow...

Im winding in 7pound of boost if thats what your asking...

8-10 psi is the safe limit for my engine without some internal upgrades.

And yes, one day i plan to rebuild the engine with forged pistons, conrods and race bearings, head studs, block guards and metal head gasket.

but for now, the motor stays un-opened.

update:

got the EMS the other day...

came off a 200sx with a tune to an SR20 (of course)

not that thats much help to me, but eh, at least it works.

came with both wiring harnesses and computer com cable.

$720 bucks shipped to my door.

Beats the hell out of $1300 brand new haha

all i need to do now is fab up the intercooler piping and the exhaust, after the manifold gets made.

then ill be ready to get it tuned.

Give it 3 weeks ill have the most powerful non-jap market x-trail in the world (unless theres another turbo x-trail ive never heard of - im sure there is haha).

STAY TUNED!

VERY exciting times ahead (for me anyway :))

looks like it should be fun. with the flange adapter that's on the turbo it looks like the internal wastegate is now blocked up? so what are you going to use for a wastegate? I'm guessing external?

thanks!

nah its still internal, strange design but the wastegate flap is in behind the top of the dump flange.

th_DSC01066.jpg

not like most internally gated turbos i've seen, but eh, does the same job...

if it flows 3L of exhaust gasses and doesnt spike 7psi, theres no reason why it wont work on same pressure and only 2.5l of exhaust gasses.

cant wait to get started on some sweet fab work :D

prob gonna paint the intercooler piping black, make it a little more sleeper...

hey man yeh its bin rebuilt.

i just sent off the centre housing to turbotech here in Perth.

just put new bolts and everything on for the sake of it u know.

managed to clock it round so the oil feed points directly up.

cos as you know on a 300zx its a side mount, and i need it to be a top mount.

is your in good condition at all?

update: got all the turbo parts lying around...

everything's installed that i can, just waiting for my manifold.

my mate does fabrication stuff for a living so it should be good!

heres the start:

Manifold.jpg

thats a laser cut flange btw :D

all i need is the exhaust (inc manifold and dump - all the flanges are made already) and intercooler piping...

give me two weeks i should be most of the way through that. im picking up the raw metal for the i/c piping tomorro so i might start measuring that up then.

ill post as many pics/vids as i can regarding the manifold, exhaust, tune and of course the dyno runs and in-car drives when its done.

stay tuned! (pardon the pun)

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day  
    • While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
    • Are you 100% sure this isn't tune related?
    • 140-150 across the board. At this point hoping the grounding harness fixes it. My grounds are all tied to the chassis and none to the battery. For SR and KA that’s never been a problem for me but had a few other guys here and Reddit who told me RB really like a very solid ground setup tied to the battery so going to try that next, I’m stumped if that doesn’t do it. Never had a car have spark and fuel and not fire off before. Only thing I can think is the spark is intermittent/weak because of grounds nothing else really makes sense at this point 
    • I am having close to the same issue. Can you help me with what wire you grounded to get your pump to trigger?
