So even more reason to buy one on the cheap and bung in the ford!

Ask chip on here, he is clued up on them.

all this talk, all the time, of saab turbo lumps. has anyone successfully put these in a longitudinal rwd ford yet? or is it still all random rumours from ppc mag?

I still think YB, easy enough swap and reliable as long as it's a decent engine/looked after. Easy enough to go for more power too.

Obviously a V6 isn't really slow but whats the point when the YB can do 300bhp easy and will be much quicker.

big_wig_074

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

PileOfRust

Anyway he said he only uses it as a daily drive to work n back.. not chasing power figures so for that reason it'd be the v6 I'd choose

casper88

Well plan is to have it as a useable daily for couple years. Then in time get some power out of it. Witch if I have 24v I can always turbo it. As I plan to run it on standalone managment ment installing it anyway. I been researching and talking to a few people and I thinking that a 24v is the best bet for now and the future . The shell I am using is a solid as a rock with quite a few uprated bits anyway. I just want a reliable everyday sierra with abit of a kick. Untill a couple years when I can have a second car and go for some power gains .

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

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

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

orion turbo

what 16v have u got?

If you are lucky you can spend Ł500 and a weekend to do the swap with the boa

You'd be lucky to do it for the time let alone the money on a yb

With a 550 shot of gas?!

I'm not a fan of the 24 valve engine. Seen them make poor power on the dyno time and time again.

A YB is bullet proof at the 250bhp mark, so that's the way I'd go.

ajamesc

Dose the one you have now have a cossie front bumper? It totally changes the look of the car makes it look much better
And one other thing as you have had both. Would you ever ditch the yb and fit old v6 in again lol

opposite lock

iTrader: (3)

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.
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.

cossie4i+

iTrader: (15)

No the Grey 4i has the standard bumper.

As i can only have the 1 toy these days i would stick with the YB, but if i had to use it every day i would fit a 24v

Isn't a V6 cheaper than a YB?

I'd be inclined to go for the V6. Just because it's easier to tune a YB doesn't make it impossible to tune a V6. Go on, be different

Though this Saab engine idea sounds interesting., anymore info on it?

xr_craig

iTrader: (2)

Not really true is it

Marcyg

Sierra 8V bottome end, Scorpio 2.0 16V head, which flows better than the RS2K one, and Scorpio VIS inlet manifold-which will probably be done away with as there's no point with forced induction.

iTrader: (3)

In my opinion .....It is.

edit...ahh i get you lol, of course ybb is true race engine , its the sound i was on about in terms of the experience of the 24v v6

zippyobrien

iTrader: (2)

Depends on your budget, 500Ł go v6
5000Ł go yb

Personally I'd fuck it of and get a 200sx lol

Damocos

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

PileOfRust

Yeah the boa's and the bob's fucking scream, make peak power at about 5.3krpm but still rev to near enough 7krpm. They seem pretty similar to the old e30/e36 bm straight 6's noise n power delivery wise, they're relatively linear. My dads boa'd Capri only feels like its pulling in 1st and 2nd but you look at the Speedo and can see its still going well,
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

Better engine than both IMO.

orion turbo

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

I use my cossie everyday to go to and from work.The YB is the more tuneable engine.The Cossie V6 engines are a good engine though.

finding a decent 24v is hard iv been looking for about 2 months and there way over priced imo but soon ill need to bite it and pay for one was looking at about 500-700 for a good granada cos but they seem to be upwards of 900-1200 some even over 1500

tjRS500

Think there the same cams, said over on fordpower...

orion turbo

there a couple on ebay cheaps at mo.

750 with nos???? means big bangs???

you been watching to much fags and furious mate !!!!!!!!!!!

iTrader: (3)

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

Dojj your the man.You now your stuff about sierras.

iTrader: (3)

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?" )

robrs2

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've heard you can use the 4.0 ford explorer v6 block with the 24v cylinder head being as its a cologne lump..

orion turbo

the 24v heads on the 4.0 block make for very big dimensions and have been told would be a very tight squeeze. and impossible to force iduce in the sierra.

it has been done in the past, but it's only been "done" as in "heads bolted on"

don't think the fronts match up though

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.
