Prelude cam???

[od2681]

hey guys..one of my friends told me that a 87-88 carbeurated prelude camshaft fits perfectly in the 3geez. I was told that they have higher lift. Has anyone done this or knows that it will work... Would it be worth it
thanks in advance

I don't know about the carb one but the 84-87 efi one should. In fact I am relatively sure that an 87,88 will not fit

87-89 prelude cams won't fit.
if you have chilton manual, open to page 3-12 and compare the lifts.

[od2681]

so i should look for 84-87 efi cams then right???

[shepherd79]

you can get EFI cam, but it will be the same one.
unless you want to regrind it.

anyone tried an auto 3g cam into a manual 3g?

[pimp86LX]

isn't it the same?

[Grant2k]

the auto and manual are the same but the EFI and carb are different, so yes, they are the same.

[pimp86LX]

how are they different? Im just guessing but does the EFI cam have a shorter duration?

[anchovies]

Anyone really sure the auto and manual cams are the same profile or just looking at the numbers provided in chiltons? Someone go mic it an auto. I've got the manual.
