yeah, the turbo had to be flipped, and the exhaust manifold had to be ground to fit.

I also had to mess with the shift linkage as it interfered with the inlet to the turbo.

I cut the relay shaft and flipped it so it angles down instead of up now, real close fit, but it works.

with a VNT, it bolts right up :D  but if you got any other sort of turbo that doesnt sit down low, you will probably have to flip it. the vnt turbos are already clocked downward facing. you can try flippin the turbo and manifold if you want. ive never tried it, so i dunno if it works.

thanks everyone for your help.

so far i have an inlet manifold....

I have the option of buying a running 1.6NA motor including injector pump. Is this going to be of any use to me? What are the differences between the NA and TD 1.6?

what turbo should i use for a 1.5/1.6 TD?

Cheers

if your gonna go with wild boost and power numbers, go with the 1.6.. if you want a few more ft lbs of torque, go with the 1.6. if you want a fairly torquey motor with tons of top end power, go with the 1.5. from my experiences, the 1.6 is ever so slightly faster off the line.. but it seems like my 1.5 has almost twice the top end my 1.6 had.

the 1.6 n/a motors were basically the same as a 1.5, just with bigger cylinder head bolts and a few other slight changes. bore size was even still the same between the two.

Thanks everyone, the project is slowly progressing from research to procurement.

I have the following parts in hand:
4T gearbox
k-jet intake manifold
1.6TD oil cooler and mount
new shock absorbers
lowered sports springs
alloy wheels with tyres

and have the option of buying the following:
4 bolt turbo exhaust manifold
1.6TD injector pump
1.6NA motor complete with pump
oil supply line to turbo
1.6TD turbocharger (are these easy to rebuild?)

What is the issue with the gasser manifold? is it the clearance between the inlet manifold and the turbo?

Do i need the following?
1.6TD oil pump? are these any different to the 1.6NA oil pump?
ARP head studs?

The main reason I'm considering buying the 1.6NA motor is because i thought that it was a stronger motor for turbocharging. What are the differences between the 1.6NA and 1.6TD? (other than the crank, rods and pistons). Is the 1.6NA head any better than the 1.5?

The main benefit i see is that i can buy oversize pistons for it. Have the supplies of 1.5L o/s pistons really dried up? I would hate to sleeve a block just to have it crack!

Once again, thanks everyone for your help.

unless you have a quantum/dasher exhaust manifold, or you flip your manifold and re clock the turbo, it will hit the manifold. GTD manifolds go out and up slightly. and mount the turbo up high. ive got a VNT 17 on mine. it comes out and goes down, so the gasser intake fit on there with very little modification.

and as for your questions about the 1.6 engines..
the n/a and turbo engines were quite a bit different. they had oil squirters, notched pistons, oil coolers (witch you already have) and the block and head were actually a different grade of alloy. you should get head studs just because. make it easy on yourself. dont risk cracking a block with stock bolts. the internals of the 1.6 td are almost identical to a n/a motor tho. i would use a turbo oil pump if you can find one tho. ive got one in my motor.

so now i have a 1.6TD pump, gasser inlet manifold, oil cooler, hopefully a k14 with exhaust manifold and the choice between the 1.6NA and 1.5NA for bolting all this stuff to.
The 1.5NA is very low on compression (roll starter) and the 1.6 is not much better. At this stage I'm leaning towards rebuilding the 1.6 as I can easily find o/s pistons for it.

In the meantime, I'll be put putting around in my other halfs half decent 1.5NA.....

i just put my turbo pump and injectors on my 1.5, and holy ***.. what a difference. my car used to struggle to go 100, but now you can just get on the pedal in 5th gear and your doing 100 mph in no time. i spanked a toyota solara a couple days ago. pretty sure those are the ones with the supra engines in them.. but needless to say, if you do all that stuff to your 1.5, it will go fast, thats for sure. cause mine flat out RIPS. i drove a newer VR6 jetta the other day, and honestly, i think my car is quicker.
