Thanks mate, bit more motivating to look at than the turbos! Now to stop spending on accessories and actually finish the thing.

Dragged the car out to try on the new wheels. Scored a set of SSR MK2's in 15 x 7 0 offset, and 15 x 8.5" -6 offset. Tyte sizes are not final though, the 195 60's on the back are way too tall. Also not too keen on the black centres, buy will leave them as is for the moment. Pretty happy with the look so far...

So i noticed a bit of a bubbling in the paint in front of the rear wheel arch.

What fell out wasn't ideal...hrmph. So i had a bit of a scratch around.

At least its only surface rust underneath, no holes. looks like the last owner just bogged over a dent rather than try to fix it.

What exactly are the ASCD sensors your after? are these for the shock control settings?

Well the Gazelle should be just about run in by now...

Do you know if there is any difference between the z31 turbo and non turbo diff?

And is there anyway to determine the ratios? 

Thanks

Not sure with Z31's but R30/31 skylines etc, the non turbos have a smaller bolt pattern on the input flange.

Easiest way to usually tell is the diff input flange is round for non turbos with M8 bolt holes and turbos are a square shaped flange with M10 bolt holes.

If still in the car, the firewall tag will tell you ratio. "transaxle" part will read RC39 for a 3.9, RC41 is 4.1 etc.

Not very good video (from my phone jammed in the headrest), but here's one of the DYO against azzuro's Fiat 125.

Only just pipped him at the line...

Ok, so i completed fitting the turbo, and got it running.

FAIL.

No matter what i tried, it was getting really bad compressor surge in top gear at high load and low revs.

So i pulled it all out again, and refitted the original setup to get it running for drag day.

I did swap the exhaust housing with my spare, as i found a tiny crack in the one i was using.

For some reason this supposedly identical part seems to be boosting and running better than it did before!?

Ah well. ran it on drag day, and overall pretty happy with the results.

Run 12 passes all day, and the difference between my slowest pass and fastest pass were a mere 0.27 of a second.

Also managed to win the DYO competition again this year too.

Best run was 14.26s @ 102 MPH which bettered last years attempt at 14.4s.

I guess lesson learnt, if it aint broke, dont fuck with it!

Turbo is all in now, and started it up to bleed the air out of coolant last night.

All seems to berunning ok, but not sure what boost the new actuator will run at yet.

Small hiccup, the turbo intake piping no longer fits. need to find some 3" pipe to make a new one...

Sorted a few more bits out. drilled and tapped a fitting for the actuator boost feed into the turbo front cover as this turbo never had one.

New water line fittings arrived for the turbo today.

These ones are 90 degree and seem to clear everything in the way...

I've had to use push lock 1/2 inch hose. 

I was planning on hard piping or braided hose, but have run out of time cos drag day.

It will have to do in the meantime until i can sort it properly.

I'm going to have run the lines in front of the rocker cover as there's too much stuff in the way elsewhere.

I'll make up some support brackets for the lines soon.

and lastly i still need to connect into these two lines under the thermostat housing.

Not really an ideal spot, but i have no other option for now. Still a PITA to get to, with the distributor, manifold and power steering pump in the way.

So after a lot of trying to figure what thread this turbo core has, i got these heinous looking things...

-8AN M16 X 1.5mm to 1/2 inch hose fittings.

Unfortunately i got the straight ones (at about a quarter of the cost) of the 90 degree elbow ones.

As i found out, they aint gonna fit...

So it looks like i've to got to fork out for the 90 degree ones. At least they are available in black anodized finish.

Also got new gaskets to mount it, but still got to modify the actuator to suit the TO4 inlet bolt spacing.

and no driveshaft off the front of the crank like that one.

needs more of this?

contact the insurance ombudsman service (free i believe?).

that will probably put the shits up state.

they were cunts to my mate, who's car was stolen/recovered and refused to pay out until they disposed of it at auction. for a grand total of $1500, and took 3 months to sort out.

having gone through this fitting a microtech to my FJ20et, i would have to say, buy new ones.

at least you know what your starting with, and not chasing issues with old possibly dodgy sensors.

shop around, there are some pretty cheap bits out there.

i think the crank angle sensor was the only one i reused on mine as its part of the dizzy.

well at least it looks like you've got a settlement.

hopefully you save the old girl.

not sure that can be certed.

if you're running aluminium wheels, i think stud pattern changing spacers, i.e. 4 stud to 5 stud are not allowed.

clint may be able to clarify, but i think 4 stud to 4 stud are ok but not 4 -5 stud.

been a while since an update...

For no better reason than I already have it, I've decided to fit a bigger turbo.

It was built up for years ago, using a water cooled core as the early garrett/air-research nissan turbo's weren't.

It's basically a T03 exhaust wheel (upgraded and cant remember the trim now) and 0.63 T03 housing,

and a T04 inlet with a larger trim wheel.

By today's standards its probably an old slug, but surely better than the original 30+ year old factory one i'm running now.

original turbo is on the left, new on the right:

and after removing the old turbo, trial fitting the new one.

its sits extremely close to the engine mount bracket, but just clears it luckily.

now i'll have to source some water feed lines to supply it with. i have somewhere to tap it into the engine, 

but i need to find a M14 X 1.5 mm banjo type fitting to connect to the turbo with.

done here too.

anyone who has owned an IRS datsun will know, you lower them, you get crazy rear camber.

i had an old guy jump out of his car, and try to stop me driving away at traffic lights.

apparently i had a "broken axle", it shouldnt look like that!

best achievement to date with that car, i made i guy fall off his pushbike with key off bangs... 

try asking for FJ20et engine parts.

or even gazelle parts, "we do spark plugs" is the usual answer...

also, no its not a supra.
