difference between vn/vp/vr buicks

[VryNeat]

i didnt know what section to put this in so i just put in general if its wrong i apolagise and feel free to move it

im sure this has been covered before but yeh just to clarify what are the main diifferences between the buicks of these series

i thank you good sir and i bow my head to u

[VryNeat]

thats power info but apparently theres a diff in compression and the ecu i think so just wanted to know that stuff

Hmmm, i know the cams are the same, but that's about all i can rememebr off the top of my head that differs from Wikipedia! I can't seem to find the manual on those older vehicles! Looks like i've oly got VS-VY now! Anyone with a manual want to post up?

vn has different cam, crank, balance ahaft, intake manifold ,exhaust manifolds and tune than vp.vp heads allso have an extra hole for the pcv valve which is moved into the inlet manifold on vp upwards.vr is the same slight mods to flow here and there different cam as well and if auto has a cam postition sensor in the front timing cover and a different tune again for vr engines

so in saying that is the vr engine better all together? theres a vr at work im buying thats got a ****ed head and rear seal so im just replacing the engine its belonged to a women so its been treated well but yeh will there be bulk issues if i drop a series 2 vn buick or vp buick in?

[delcowizzid]

if its VR auto there will be work require installing the vn-vp engine as they dont have the cam sensor and the vr tune is way off for a vn-vp engine as well would need a custom tune to suit vn-vp engine and vr auto setup if its manual sweet chuck the engine in and slap in a memcal out of the same series ecu all done.vn engines had the coolants sensor in a different place too and will require the wires being redirected to the sensor if you run vn engine on the vr harness

[VryNeat]

its auto so essentially ur saying i should just get the vr engine

[delcowizzid]

i myself would slap on some head gaskets LOL but yes better to just get a vr engine will save so many hassles in the end

[VryNeat]

the fact that the rear seal is GONE means itd be smarter to just drop in a new motor

vn-vp run 8.5:1 and the vr runs a compression ratio of 9:1
also apparently the vr came out with the supercharged rods from the states...

delcowizard pretty much explained it all (i think)
