Hydraulic Lifters

I found a link for lifters (part of the cylinderhead that is pushed by cams)

http://cgi.ebay.com/ebaymotors/ws/eBayI ... 2457331748

'76 - '77 4 cyl 1393cc
"Chevy" 1.4 eng w/OHC: Chevette, Chevette Scooter

'91 - '93 4 cyl 1598cc
"Korean" 1.6 - 6 (L73) eng w/OHC: Lemans

'76 - '87 4 cyl 1599cc
"Chevy" 1.6 - 6 (L73) eng w/OHC: Chevette, Pontiac T1000

'82 - '86 4 cyl 112 (1.8L) J & O OHC
"Pontiac" (Brazil Engine) "O" eng fuel injection; "J" eng fuel injection, turbo

'87 - '94 4 cyl 122 (2.0L)
"Pontiac" OHC "H", "K", "L", "M"

What I find really interesting here is that the 2.0L "M" engine is the C20E turbo engine, the "K" is the LeMans 2.0L engine and the 1.6L L73 "korean" motor is also from the LeMans.

This means the L73 in the LeMans (Daewoo product) is in all likelyhood the same as the Lanos 1.6L A16DMS.

This is good from the standpoint of being able to replace the engine.

It's kinda funny that the 2.0L and 1.6L Daewoo engines are simply updated versions of early nineties GM engines.

Given in the early nineties GM was the primary owner of Daewoo I can see why our engines are found all over the GM family of vehicles.

are these lifters better then the stock lifters??

and what are the advantages of having better lifters?

I don't know if they are better, I just wanted to show that the lifters crossreference to all kinds of engines.

The advantage of lighter lifters is less weight in the valvetrain which results in the ability to run at higher RPM.

Basicly the inertia of the valvetrain is what limits the RPM levels.

If you used very exotic materials like they do in Indy cars you would be able to achieve way more RPM before you had any problems with things like valve float.

Valve float is when the valve doesn't close like it's supposed to which can lead to damaged pistons,valves,cylinderhead.

Basicly if the valve stays open too long the piston slaps it and whamo your valve bends and your cylinder head cracks (happened to GsiTurbo last summer)

This is interesting...I did cross reference on the Opel EPC (Electronic Parts Catalogue) and

Lifters C16NZ engine
GM Part #: 90295215
Kat #: 6 40 051

Lifters C20NE engine
GM Part #: 90295215
Kat #: 6 40 051

So both the 1.6 and 2.0 engines are using the same lifters

do you think that maybe cams and rods might be the same part??? for the 1.6 and 2.0??

The 2.0L is about 3/4" to 1" longer so they probably don't share the same cams and I doubt the rods will work either (but you never know)
