Whats better?.....

A&Q about 350Z
Q:

I had my mind set on a 20vt engine transplant to a mk2, however my bro swears 6 cylinders are better than 4, and says I should do a vr transplant.
The car will be daily driver so I need reliability and reasonable fuel efficiency would be nice too. The vr would be cheaper, however the 20vt would be more powerful-tho im not certain of torque differences.
so, vr6 vs 20vt - whats best for daily driver????
A:

Ask yourself how much power you want, first.
A:

between 200 to 250 bhp, im not trying to turn it into the millenium falcon!
i want a car that can cope with traffic, then be evil on a track when i start to do trackdays.
A:

Small engine with big power potential.... less chopping around of the chassis , and more fluid handling with the smaller engine, IMHO.
A:

no replacement for displacement imo :D
A:

I'd have the VR, but if you want to hit 250bhp on the cheap, then the 20VT is the way forward.
A:

no replacement for displacement imo :D
Yes there is. Boosted Displacement!
A:

Personally I'd go with the VR but that's just me. It's a tricky one to say for someone else though because of the power you want.
Get a 2.9 Corrado engine and you'll be seeing 200bhp easy enough, but like Phil said the 20VT will be easy to get to 250bhp. I don't know how much more you would get out of a shrick inlet manifold on a VR but that would be within your budget if you was planning on a 20VT in the first place...choices...
A:

I went VR6 over 20VT for a few reasons - firstly, the cost of the initial transplant, the VR works out slightly less, and then, in terms of tuning potential, if your wallet is fat enough there's some serious power to be had from the V6.
Oh, and then there's the noise

Leave the VR6s for big 400BHP turbo terror, trye shredding applications
in a MK3, Passat or Corrado pefferably.
20V iT. Small Lightweight and Kompact. Go into corners like a rat and exit like a rat with its posterior on fire etc.
A:

what about ease of installing, I pretty much know what I need to do now with a 20vt, are the vr's any easier to put in? Im a novice at best with this sorta stuff, and these engine swaps maybe biting off too much for now, but I dont want to put in a 2 litre bottom end only to swap the full lump further down the line.
I dont really have a target power, I know I would be looking at 275 bhp for the 20vt swap which I think is plenty. It will be an ongoing project, I could definitly live with 200bhp from a vr if that was the option I chose.
What about reliability? is there much to choose between the two?

thats not replacing the displacement tho
Supercharged VR6 :D

The VR for reliability. there's stories all over the shop about 20 valvers going pop.
A:

i had a golf mk4 20v T and mine when pop the ecu bloow but dont get me wrong it was an awesome motor, iv went for the vr6 this time round

so its a case of less to go wrong on a vr then. something to think about.
are there many stories of 20vt's going pop, and were they highly tuned or pretty much oe?
A:

regarding the various claims of the 20vt being smaller, lighter, more compact. i think theres about 20kgs difference in weight between them when fully built with manifolds and all ancilliaries.
another thing to consider is the vr will be more user friendly in bad weather.
also if you look at the vw cup race series, the v6 engined cars have generally won more than the 20vts have.
A:

There is significantly more to go wrong with a turbocharged car, another reason to stick with a n/a motor.

turbo's not good in the cold?
vr's won more in the cup, is that based on the same number of races entered?
A:

no replacement for displacement imo :D You'd go far in the States!

Nope turbos are more efficient in cooler weather.
A:

r32 engine,

Quite right!

well lets face it - its colder up norf !
A:

its 10-6 to turbo.
A:

depends what you want and on what budget. As said you can't beat displacement for ultimate power (with some forced induction). but it all depends how far you want to go.
the 20v will be cheaper bang per buck (drop a TT engine in with a remap and have an easy 280bhp)
but if you're happy with the lower end of 200bhp then a VR will happily do that.
On the other hand you might be able to pick up a VR and fit it for a reasonable price and then get a supercharger for similar power figures.
Personally i've gone the 20v route.. ran my TT engine for 3years with a few track days + road use and nothing went wrong until the car met with a lorry.
only faults it ever had was a wiring snag (nothing to do with the engine was a loom that was made), a coil pack went, and i split my intercooler. None of which are catastrophic and could all be fixed relatively easily.
