Yes it is possible to put a 1.9 head on a mech engine.
Many have said that the 1.9 ports flow better, but I have yet to see a flowbench of a 1.6 head with the 1.9 valves in it and a 1.9 flowbench with its appropriate valves. IMHO the 1.6 should flow just as well as the 1.9 with the bigger valves. . . To answer your question there is room on the seats for the 1.9 valves on the intake and exhaust as long as nothing is hurt to begin with.
If you are going to bore it, which if I were you I would, I would just add the squirters in you block at that time. It is just a bit of machine work and 4 squirters.

The engine I am putting together came out of a 83 pickup but I think its a replacment engine from a sticker on the side of the block, also the block is black.
To me it looks like it is set up for sqiurters because there are plugs in threaded holes where they would go. I can try and take a good picture of it and post it.
Where can I get the squirters? Also would I need the bigger oil pump with them?

Hello, I got a Holset H1C turbo from a 94 Cummins 4BTA 3.9L for free, Its in great shape and was wondering if it would work on a 1.6 VW?
But after some searching I found out it has a 16cm2 turbine housing. Is that way to big to spool on a tractor like I am building?

Please tell the wheel sizes and A/R of that turbo. That it came originally on a 3.9 liter engine sounds about right for a tuned 1.6.

H1c is a big turbo I don't think it ever came on a 4b but I could be wrong, it was more common on the earlier 6bt cummins found in dodge pick up trucks, it is basically the same as an hx35 just a bit older. I don't see it working well on a 1.6 even in compound, but I'd love to be wrong since They are cheap and plentiful

Compressor wheel is about 43.5mm x 73mm with 7 blades. Turbine is about 60mm x 70mm. Turbo assy# is 3522900 serial# is H 284170. I have no idea on the AR number. They don't list it that way. It is off a 3.9 cummins I know that for sure. I can't read numbers on turbine housing anymore but looking up assy# says its a 3521927 turbine housing and is 16cm2.

43.5mm is a good inducer size

That compressor wheel is good as Trevbor said, should flow to about 200-250 hp.
That turbine wheel is huge. You will have spooling problems no matter what you do, other than feeding
it nitrous or running a compound setup.
Maybe you can get another turbine housing and wheel for it?
What is your power goal again? Fit that turbo with a ~ 50 - 52 mm exhaust exducer housing and wheel and you should have a good turbo for ~200-250 hp.

Power goal is as much as I can get without spending tons of money lol.

I am not set on using this turbo. Unless it might work on a compound setup as the second turbo?

I measured it with housings off and digital calipers.
I still want to find a T3 turbo to make a T3/T4 turbo. I found one for $200 but don't know what turbine housing is on it. Its from a small Allis Chalmers 4 cylinder, also don't know what shape it is really in. I want to get back there and check it out closer.
I have 3 TO4 turbos for compressor side but two of them are to big for our rules. can't be bigger than 2 inch at face of wheel.
I assume those cheap T3/T4 turbos on ebay are basically junk? Can they work if rebuilt with good bearings and thrust?

yes, they can be made to work if you rebuild them with garrett parts..
they still have casting flaws in the turbine wheel and shafts tho, so beware..
if it were me, i wouldnt use more than just the turbo housings off an ebay turbo.. seen too many horror stories from those..

That is what I figured. Like anything else you get what you pay for I guess.
