Subject says it all. I'm stripping the block (finally) this weekend and I need to order the rebuild kit for the 1.6NA I'm building. I'm converting this to a TD, so anything i should modify while I'm doing the rebuild?
Thanks
Rob
While it's already stripped, look into having it machined to accept some oil squirters from a TD, and notch your pistons to clearance?
There are quite a few posts on this mod in the archives. The biggest problem in my opinion can be sumerized into one catagory--Heat.
The NA should be strong enough to handle mild to stock boost preasures. Especially if you do a solid rebuild. Are you planning on reusing your pistons or replacing with new? If you are going with new, why not just go with TD pistons? Cut out problem solved. You would still have to have to have the block drilled and buy the oil squirter setup, but that would solve the lower end heat problem. Or themal coat old pistons.
Just had a thought, what year is this engine? I have read here that the difference between the TD head and the NA head is different by year. Late model heads may actually be the same. Thats just going off memory and someone will have to back me up on that.
Heat, back to it. when you add the turbo, it will need oil lines to the pan for cooling/ lube. New pan or drill and tap or weld. Ahhh.. man there are a bunch of other things to go with this but I need to go get some more coffee right now, I am still dragging ass. You need some more parts, control and moniter the heat, get the heat out. Do a search, make sure you put AND between you search words. Good luck

The engine is from an 84 Jetta. I had planned on taking it to my machine shop and having it inspected thoroughly before making determinations as to whether new pistons were necessary or not, but thermal coating seems like a good idea in a general sense, especially considering i plan on boosting this engine.
There seems to be some difference of opinion as to whether or not the oil squirters are necessary. I plan on running an intercooler and an oil cooler, both seem like a wise choice in any case, but if i do that do i still need the oil squirters? I don't mind spending the money to get it right, but at the same time i don't want to overcomplicate things either.
The idea is to build a reliable motor with off-the-shelf parts making smart upgrades as required for power and longevity.
Thanks for the tips!
