RE: (Tech)1.9L Head swap questions

[Randy Block <RandyB@E-Risk.com>]

Masun,
The 1847tt I am running is built on an EN (1715) block and is running a
modified 83-84 GTI (big valve/solid lifter) head.
The engine originally had 9.4:1 compression and with the head decked a
little it is now about 9.7:1.
If I remember correctly, the oil return passage on the GTI head had to be
welded shut and re-drilled a smaller dia. but fit as OEM otherwise.
As far as the Corrado head goes I guess you could make it fit, but what is
the advantage? (bigger valves-hydraulic head?) Have you measured the valves
on the head of the 1.9, are you sure it is an earlier head (1.6/1.7). If the
water inlet is on the passenger side of the head (near the cam sprocket
side) then it probably is, if the water jacket is on the drivers side than
it is probably a 1.8 head.
Are you sure it is 8.2:1 comp. seams kind of low for a tt motor.
If it was me, I'd source a GTI solid lifter head and use it.

		List, 
		I know some of you may be able to help me out with this
dilemma. I just got 
		a 
		90 Corrado G60 that has been hit in the rear. Car ran great.
147k on the 
		odometer. I bought the car for the seats which have been
transplanted into 
		my 
		78 Scirocco both front and rear fit with a few mods. I was
going to put the 
		motor in my 78 but I have a 16V I am installing next
weekend. So, I gave 
		the 
		motor, dash, and wiring to friend (inactive list member)
named Steve 
		"Ghengis" Min with an 81 S currently with a TT 1.9L block
and 1.7L (EN) 
		head. 
		According to the 1.9L specs it is at 8.2:1 which is a
perfect compression 
		for 
		a G60. 
		(Randy what head are you running on your TT 1.9L?) 
		
		1. Will the 1.8 (PG) G60 Digifant head fit on the 1.9L
block. The 1.9L 
		block 
		originally was a 1.6L block according to the TT paperwork? 




	No,it won't fit. The oil passages are different and the head would
have to be 
	modified. 
	
	

		2. If it does fit would it be worth the effort to swap the
head? 
		Any help would be appreciated. 




	It would be worth it,..but it is a PITA as one of the passges must
be plugged 
	or welded up. The other must be welded up and redrilled, or some
sort of a 
	reducer must be pressed in. What is left of the Corrado, anyway? Is
he using 
	the FI? brakes?
