how much money do you have?whats it for?
a yb will cost WAY more and you also need the gearbox etc etc.....
a v6 can be done on a t9 box and will cost less but never came in the sierra standard so needs a bit of fettling.
do you like the feel of smooth power delivery or do you like a kick in the back?
how far do you want to go in the future?
for future tuning potential its got to be the yb, if you can afford the kit in the first place.
for nice sounds, smooth delivery etc... its the 24v

I have had both in 4is (and Cortinas), for a easy to drive everyday car the 24v is great. You can drop down below 1000rpm in 4th and it will pull to the limiter if you wanted. You can drive it like that or stir the box to speed things up. Instant power, so great around town, so much easier to drive in traffic.
YB is bulls out fun, but i would use the 24v daily with no worries
Crap pic of them both

That white one looked awsome! It just looked really aggressive with that ride height and those wheels

24V any day of the week. The torque is highly addictive ![Top](https://passionford.com/forum/images/smilies/smile011.gif)
I need to know more about the 16V turbo. I got a 2.0 16V in my Sierra and looking to turbo it next year

They are chalk n cheese but at that power level a 24v is so much more fun ime.
The mad thing is they did the 24v for refinement but soon as it see,s a nice free flow exhaust they become a different beast . I absolutely love driving my mates one i couldnt care less about the power tbh its the experience of it.
A YBB can be civilized with lovely refined sharp torque but will NEVER sound like a true race car.
They are old they are heavy lol but who really cares its the image which is so good and suits the Sierra perfectly.

Both can be reliable...... Depends on history on both engines and also what mods have been done. I ran a 4x4 cos for 4 yrs and the only time it let me down was a blown dizzy cap. 320bhp and a daily driver
Now have a 24v and these engines are good if you get a decent one, BOA is reliable providing the timing gear is ok..... These are the known week spots on these engines. I had BOA and was brill, now run a BOB which on paper is more power but slightly more difficult to get running. Have done 7 yrs with these engines now and i can honestly say that they are very good std but can still give trouble if they have not been maintained properly. They dont like mega revs and they need good oil, week spots will be bottom end bearings and the timing gear. Beyond that then you can have good fun with them, they sound great and are fast enough for a 200 brake car. I have turbo'd mine now and it did cost me a few grand to do but the results are impressive for the boost im running and it will match a stg 3 cos in terms of power and driveability. So based on that i would say the following.....
YB if you want a turbo
Cos V6 if you dont
If you do then its gonna cost you the same as dropping a YB in but it will be different and the sound will be epic

And so is a BOA , i've always thought they rev more than a yb in std trim , the torque they give is much more user friendly for a daily driver.

The mad thing is they did the 24v for refinement but soon as it see,s a nice free flow exhaust they become a different beast . I absolutely love driving my mates one i couldnt care less about the power tbh its the experience of it.

Bob cams are ment to open up earlier in rev range and add 10hp, 2.5 vectra injectors apparently add power.. and there's rumours that them 2 together with an emerald ecu can get you to 270hp+ but I'm not sure on that one.
One thing though, keeping the Granada cossie airbox and using that instead of a k+n cone filter helps keep the power up since the engine won't be taking in hot air from the exhaust

rs2k cams in the scorpio head is even better. did the head just bolt straight on the sierra bottom end with the scorpio manifolds?

when a certain tuning compnay said they had produced the magical 500+ brake with forced induction from the 24V everyone said it wasn't possible as "the standard inlet/plenum is only capable of flowing 280 brake worth of air"
cue loads of slagging of said tuner
fast forward a year or 2 and a certain mr kershaw from famous turbo making company unveiled his 500+ bhp 24V twin turbo
using the standard inlet/plenum
everyone started sucking his dick as "it was only a matter of time before someone pushed out 500 brake from one of these"
they don't like nos in big doses and they don't like big revs as there is too much flex in the block
but with forced induction pulling the powerband lower down the rev range, they are fine and dandy as long as you give them a freshen up before you start the search for big power

the big downside with the boa is it's weight
you need some properly sorted suspension to deal with the extra lump over the front because while it may have the power to drag you away you also need better suspension to handle the rolling plus better tyres AND better brakes AND better suspension top mounts (mine pushed their way through the strut tops after a while
strangest thing i've seen when it comes to the question of "my suspension is fucked, what could it be?"

24v for me. Had BOA to start with, big end failure got that. Couldn't find a new BOA so I changed to a BOB.
Much better engine.
Add some turbos to a 24v. Low pressure boost , up to about 0.5bar.
Or do this

I will try and speak to Terry my engineer and ask him what he did to the BOA to gain the extra power he said it made . I remember him mentioning it once but didnt take it in but it sounded weird . N/A spec he reckoned 320 from memory not sure but he dont make things up.
