difference btw s13 & s14 front cover/oil pump?

[N.O. Accorderz]

can i use the s14 sr20det front cover on my s13 sr20det?

will the s14 sr front cover seal fine on the s13 sr block?

anyone have pictures of both?

i believe that you can't because the s14 SR cover is cast different because of a second oil port in the block for the vtc, the s13 SR dosent have vtc so castings would be different, now i am currenty running a fwd oil pump on my s13 SR, but there are three differences. the bolts that come through the head into the cover, the one under the cas gear dosen't line up. the s13 SR pump is a higher volume unit than a fwd or NA s13 SR, this is basicly because the factory turbo has no restrictor in it to regulate oil flow into the turbo, and the turbo SR's have squirters under the pistons. and last the timing mark is about 3/4 of an inch off which is about 10 degrees. other than those things it bolts right on.also i have been running the fwd pump since i rebuilt my motor have put about 8,000 miles on it in 6 months. also the turbo that im running has a built in restrictor because it BB. the timing part is easy if you have the consult port hooked up and know someone at nissan.
