ok when i bought my car it came with two spare engines, i was told that one is an Original GT-X L20 and the other is an L28 from a Z. these engines are pretty bare, basically only blocks /heads and internals, no carbs/manifolds. what do i need to look for on these to identify aside from removing the oil pans and looking at the pickup?? will the sump be in different places?
i will probably just keep the entire L2o engine and the L28 head/ crank, but ditch the rest as L28's are very readily available in the USA.
so can anyone post where the stamp on the block will be and what it will say?? i dont think it will be like SR20's or KA24's, or even honda engines are very easily spotted.
As with what 'datsunfreak' said. The block should have a flat surface that stamped below at the #6 end of the block (ie. where the transmission bolts to, underneath where #6 sparkplug is. It will look something like this;
Skylines are FRONT SUMP. The rear sump you have will be the motor from the FairladyZ.
also i have three different valve covers that all say something different.. is there any valve cover thats more rare than another (besides the S20 that is... HAHA)
Which covers do you have?
The 'standard' NISSAN OHC in thin font,
The NISSAN 2000 OHC in the same font,
NISSAN in big block letters.
NISSAN in small and TURBO in big block letters.
They're all variations of the standard shaped cam cover though. A rare cover is the one with a squared section above the cam gear that has "OHC" cast into it. Or "3100" you can imagine why, I'm sure.
