2G heads on a 1G engine

[wings9191]

Tried looking for some info but couldn't find what i was looking for.
I am getting a 91 Tsi lower block to put into my 91 Tsi.
I need to put a head on it though.
I have a proper heads for it but it's been off the engine for 7 years and has 105,000 on it. No problem money is tight and the car MUST run very soon.
I also just blew the tranny in my 95 Tsi, which just months ago had it's head rebuilt.
I have read about swapping heads but can't find the particulares about it.
In a nut shell, can this go on there fairly easy and without tons of mods?
Thank you

Yes.

Just get the headstud holes drilled out by your machine shop and do the oil port mods and your all set buddy

You'll also want to use the 2g intake manifold too.

 

[ilco187]

only thing i would look at is the difference in port size, it been so long since i could remember what is what but 2g has smaller intake ports i thought.

 

[SpawnedX]

2G is smaller port, correct.

You will need the 2g thermostat housing

^Incorrect. The 1G thermostat housing will work just fine. Here's a pic comparing a 2G head (top) with a 1G head (bottom); note that both have the main "triangle" for the three mounting bolts of a 1G thermostat housing. If you are using a 2G thermostat housing you must use a 2G head.

Also, you can use the 1G intake manifold. Performance may suffer slightly but it will get you going.

Well that killed it right there.
Very limited on cash, i'll call and check but ya that will probably kill the deal.
But i will call tomorrow.

Ok so the intake ports are different sizes, when doing this swap you put on the 2g intake then?
Because i have the whole thing still sitting untouched in the 95.
So i have all the parts for both.

Ok so i assume this is the Mod you are refering to.

My only question is how far down do you grind as in the drawing?

Of course i don't want to go to far.
And this cross section is of course at the edge of the hole.
The images look as it is tapered off on the gallery of the head.

Ok did that make any sense?
Sorry it sounds right in my head

why are you using a 2g head?

 

[wings9191]

why are you using a 2g head?

Because my original has 105,000 miles on it and it's been sitting for 7 years.
4 months ago i dumped around 600 bucks in rebuilding the head on my 95.
Last week i fried the 95 tranny.
So i have a great head and an engine that needs a head.

Get a new motor from torontojdm.com best deals on motors hands down!

 

[wings9191]

Again as stated earlier, cash man.
I'm not trying to make an 8 second car, I'm looking for the quickest fix that will work.
If a 2G head works on it no problem.
Well except the drilling.
But i do know a bunch of people in the bussiness so i should be able to get that taken care of hopefully fairly easily.

I will need to use the 2G intake with this correct?

 

[19Eclipse90]

Again.

 

[wings9191]

Again.

So are you saying the 2G intake won't work?
Or the 2g will just be quicker and cheaper?
Thanks dude

 

[19Eclipse90]

Either intake manifold will work. The 2G intake manifold matches the intake ports in the 2G head which will perform better to a degree than a 1G intake manifold. Without many performance modifications, the difference will be tough to tell.

I would personally use the 1G manifold if you have one. It will mount the coil pack and power transistor unit where the harness can reach them for sure. The 2G manifold may not. You can do what you will though.

Cool, i just got done reading a huge thread that kinda missed the point of the topic and turned more into an argument
I have both manifolds.
I see the differences in the ports and understand all that.
I agree that a 2G will perform correct to a degree because the ports line up.
I guess my big question on the 1G intake is that port is quite a bit larger then the 2G.
I seen people talk about porting the head.
But some seem to not and just bolt it up......doesn't that cause some kind of air flw issues when the incoming air hits that 1/4 inch ridge all the way around the cylinder head port?

 

[SmoochDarling]

If you have the 2g IM use it with the 2G head, it has smaller ports to match the head for a reason. Drill out the holes on the 2g to accommodate the larger studs and your set. There is a TON of info on this site about the differences between the two heads, and of why to use either head setup.

Ok i think i am going to go that way for the moment.
I am burned out reading this topic honestly.
I think i am going to throw the 2G manifold just to get it running and go from there afterward.
Thanks for the help guys.
If you have anymore tips or info i would love to hear it though.

19Eclipse90, have you done this before?

 

[19Eclipse90]

It would cause a bit of turbulence; how much turbulence depends on how much air is flowing through. Again, on a near stock vehicle with few performance modifications, the effects may hardly be noticeable.

19Eclipse90, have you done this before?

I've never had to do it, no. I like convenience and will take that over power, but the 2G manifold will get you going just as well. Good luck getting it all together and running!

here is how to drill out a 2g head to fit a 1g block...

as far as oil port mod1 goes.. it dosnt have to be that deep... about .080-.100 and your good

 

[wings9191]

Thanks 19eclipse90 thats exactly what i was wanting to know.
Don't be suprised if i hit you up with a question or 2 but you nailed it dude.

Bogus, checking into that thread.
Thanks guys!
