vr engine in vn

[SUSS]

i know i have seen a thread on this sumwhere and i have searchd for the past 30 mins and couldnt find it. im thnking maybe it was on a another forum.

neway,

i have a vn exec manual, my plans are to buy a vr engine, rebuild it and put it in my vn,

now my first question is, will the vr eingine just drop in easily, as they are the same motor..so all the wiring and bits and pieces will b prety much straight forwrd, or will it be different?

secondly, wen i rebuild the engine, im looking at geting an upgrade of pistons, cams, rockers, port/polish heads. i only want to achieve roughly 140-150rwkw, what parts would u recomended? so i have a rough idea of what the boys in the shops are going to tel me wen i go down and visit them.

as u can see i dont know that much stuff about cars / engines.

thanks.

the vr engine is axcactly the same as a vn engine so it will drop straight in but you might just have to get another loom to suit but not sure, if you are thinkin bout doin a conversion just put a vs ecotec in as you will have more power from stock but there is just a little more fiddling, theres is heaps of info on the ecotec conversion too as hozy did it to his vn not long ago and made a thread on it.

If the heads are good and you run a Wade 992A cam you will make between 140 and 150 rwkw with a decent exhaust on it, no other mods needed

na not to keen on the ecotech, i would rather put the vr buick engine with a few mods so i leave the ecotechs behind

greenfoam, that wade cam im guesing is a very big cam? which would be very lumpy at idle? im trying to get as less lumpyness as i can get if you get what im saying.

if anyone has a stage 2/3 crow cam? could you comment on how lumpy your engine?

ive done a little browsing of the net ceen some folowing items.

ACL Race Series Engine Rebuild Kits - acl race series pistons
*crow came stage 2.
*Yella Terra 1:6 roller rockers
* port polish heads?

like i sed i know nothing about engines, would all this gear suit itself? or is it all un even?

I wouldnt bother with a stage 2 Crow cam mate. Go stage 3 atleast, but personally I would go with a Wade cam of some sort as suggested by Greenfoam.

NO the VN, VP and VR engines are not the same and are not interchangable, they just all look the same. Apart from a additional cam angle sendor on the VR engine, the VR engine has higher compresion thus would not run properly with the VN setup.

A bit of compression wont change anything mate you can run a ecotec off a vn computer so why cant you run the vr engine of it ?

if you read properly i said it would drop straight in but you might need a loom to suit but what i didnt write was also maybe the ecu cos i figured it would run differantly

Has anyone got a wade 1250 cam? what type of power is that and apparently you dont need the computer modded to run the cam, but if you get your computer suited to it will gain more HP

Is there alot of difference in the 2 as i dont really know much about cams
is it worth fitting?? and what is the normal cam specs of a VN V6 S1 does any1 know thanx.

[TrevVNVS]

Very random question, but i guess the guys on here are on the money for VN and VR's... can you run a VR inlet manifold on a VN series 1? Is there any difference in the block on top? I know the coolant pipe moves from the back to the front, but is this a problem with changing the manifold? Just looking to modify my VN and i have a spare VR inlet manifold kicking around the place (DIY twin throttlebody set up)

Cheers,

The coolant passages are different.

Gregories manual lists the reasons you can't but mines in my car and its 12:30am so I aint goin to get it

But nah it wont fit.

[padrickz88]

wow! a 992a gets you that much power? thats insane what would be the biggest you could use on the street? would the 992a be the biggest or a 1114a?

i find it interesting how a cam can make so much difference

[greenfoam]

I said with good heads the heads gain you half the power and the cam the other half. With cam alone or heads alone you would be looking at 125-130ish rwkw at the best case. But on a ecotec you could/should go straight to 140+ on cam only since the heads are good allready. The 992a is only a little cam really, just a bit of a lope at idle but it's a good cam maybe the best cam for a mild street driven V6 . There's a few different versions of it, that's the tricky part . I still have the tune from powerslaves car if anyone builds the same setup it's there fo you.

The VP/VR manifold does fit on the VN/VN heads but you need to whack some holes for the crankcase breathing in the heads (big drill bit with rags in the valley and strong hands ?)

so at the end of the day i can put a vr engine into a vn? yes.?

Yes its a bolt up fit.
