Title: need some franken parts and advice
Post by: mean88 on April 15, 2011, 08:44:48 pm

I need a part number and place to order a good 1 notch head gasket.  I would also like to know what head studs to order and where as I dont want to use the stock bolts.  I am building a 1.6 HYD with a 1.9 HYD head on it. I am also adding a t3 turbo.  The pump is stock, just rebuilt with new injectors.  I was also wondering what the timing should be, I ve read as much as 1.25mm for extra advance.  Suggestions?  Thanks
Ted

I used a 2 notch head gasket. I played with timing for a long time until I settled on 1.00

With a aaz k14 an intercooler running 17lbs of boost, gov mod and pump tuning, I can do a 0-60 run in 9.5s and not be above 875f egts. Cruising at 60-65mph is 500-600 on flat, no higher than 750f on the steepest highway grade going 60mph. Hard to get it above 950f period. Now I am worried about slipping the clutch, it has a 16v clutch, but rolling in 2nd if I lay into it it will break the tires free. It pulls so hard in 4th that it hurts my neck if I do it a few times.

intercooling is what turned my motor from pretty good, to holy crap.

Lucky day if you act fast.
Only ONE left in stock - www.rockauto.com has them on closeout sale. One Notch - Beck/Arnley

$3.06    :o

If that link doesn't work - go to their website and use 85 jetta TboDzl as car input criteria. I was roaming through there the other night and spotted this deal.

Good Luck

ARP has ones that are made for the TDI now.
We used to use the ARP that is listed in the FAQ with the title ARP part #

I would start off timing it at the normal 1.00mm. From here all you can really do is time it by ear/performance. It will need to be advanced until it stops missing at idle and the smoke clears up but stop before the clattering gets worse. It's a trial and error thing when you are building a hybrid engine.

BTW - the gasket i linked is the fiber style 1.6 (stock).

Happened to wonder if you were actually wanting a 1.9 Multi Layer Steel head gasket.

The fiber with studs - supposed to be good to about 20-25 psi boost.

The MLS goes up to higher psi boost.
But requires very strait deck and head tolerances.

fwiw
