no skylines are very nice cars and very tuneable but also cost alot too! and need to have more power than the cossie to be faster! as in a 500bhp skyline wont be as fast as a 500bhp cossie but the skyline is a much better car but cost more too buy and if u go past the point say 500 - 600 then i can only imagine how much it would cost to do the box diffs and clutch in one!

 

why wont a 500hp skyline be as fast as a 500hp sierra?

 

thats fair play mate im not digging at u everyones into different things i just think the yb is the better engine than the v6 if u are after performance

 

becase its a much bigger heavyer car and its 4x4 have u ever felt how fast a 500bhp cossie with the same torque spins up lol

 

hardly any difference in size? maybe a difference in weight but a rwd skyline like a gtst wont be much different bhp/tonne to a cossie. then theres the torque, then the power delivery
and no i havent been in a 500hp sierra. most powerful car ive been in is a bentley conti gt

 

From the quoted T3 per bank: yes (probably). The smarter people among us could probably work it out from compressor maps etc.

My point was it doesn't seem that far fetched to get 500bhp from a 3litre engine using 2 turbos.

 

my 300+ turbo v6 will make me happy enough and i can still pay my mortgauge for a three bed cottage and double garage!

 

whats different?your car has cosworth bumpers,skirts,wheels and interior!
if yb's werent as good as a v6 then you would pay Ł150 for a yb and Ł1500 for a v6.the vast majority of folk will have a yb over a v6 as its so tuneable,you can get power from it easily and the bottom end is good for 500+ bhp as standard.if you can get 300 bhp from the v6 with a Ł150 turbo and some home engineering and its going to be the best thing in the world then why doesnt everybody with a v6 have this done?
i have had a n/a 2.9 v6,was a great engine and i have had several yb cosworths and imo the yb is best.
the comparison isnt veyron w16 and yb,its v6 against yb and i like the yb best.end of.

 

id rather have a 4 valve per cyl cologne than a 4 valve per cyl pinto lol

 

 

lee , i couldnt care what you think, you will spend a fortune making your car go fast only to break it for less than it cost, then buy something else to do it all over again! i would rather save my money and do something worthwhile!

 

have u ever parked the too next to each other lol and a rwd cossie is 1206 kg and r32 rwd skyline is 1280 kg r33 4x4 1360 kg from what i can see on google

 

depends how fat the driver is

 

everybody doesnt turbo the v6 cos not eveyone has the skills and ability to do so. I am fortunate to know what im doing with this kind of thing, and dont need to pay someone to do it.

 

so if the sierra was two up with a full tank then the nissan would be much lighter, six and two threes i would think

 

im fat

 

either way, the skyline is the superior car but thats off subject lol
how does a twin turbo 2jz sound in a capri?

 

Just took a look at you link and come across this one http://www.youtube.com/watch?v=YN46R...eature=related


Thats one lucky driver

 

Thats like me saying I could beat a touring car round a track of it had 3 ton of ballast in it

 

fuck doing that in an old ford

 

......well, could you?

 

a person and 40kgs of fuel is not the same as three ton?

 

more like .140 ton, 21.42 times less than you suggest

 

my v6 bottom end is good for 500+ bhp as std, and my comparrison with the veyron engine was relivent because they are using a bigger engine to produce more power, thats how it has worked for years, turbos help both smaller and bigger engines to make more power. but at the end of the day a bigger engine will always make more power with the same mods (turbo, cams headwork etc) thats why the bttc and wrc cars have always been restricted, bigger engines make more power! am i wrong? take it up with the fia

 

You were suggesting that a laden down saff would be comparable to a skyline in terms of weight. That may be directly true, but it's not a fair comparison is it .

Both cars, same amount of fuel, same driver and a track would be better

 

lol, point taken, my saff would win it has the biggest engine

 

No disrespect (been following your build thread and like it! ) but 300bhp saff vs skyline GTR round a track.. NO contest imho.

 

and if the r33 had a full tank too subs and 3 poeple in lol swings and round abouts not to mention the 4x4 drag as im on about a rwd cosworth!

 

The skyline gtr not the new one weighs 1540 kg which is approx 333kg heavier than a 2wd cosworth so no a 500hp skyline wont be as quick as a 500bhp rwd cossie

 

Just buy the cossie V6 put it in the car try it if you like it leave it if not pull the engine out,sell it and stick a yb in.

 

I'm surprised no ones pointed out that there both prehistoric boat anchor engines with fancy heads

 

But one of them the yb still dose its job as good as any other engine out there tunned in a road car!

 

bin them both and sick a v8 (ls engine) as a 2 freinds of mine have got them in there es cos shells and have drove them hard for a few years now with 400 bhp at the wheels and never skipped a beat

 

agree!

or someone else said 2JZ supra engine.


anything but the gutless V6 cosworth engine!

 

I've had the 24v in my Capri and currently have the YB lump, there are pro's and cons to both. The 24v was quite a cheap conversion to do and a big step up from the old 2.8i it had but the YB is in another league compared to the 24v although it has come with the price tag to justify it, really its down to how much power you want and how much you want to spend. I am running around 360hp and it just constantly wants to go sideways, its borderline silly to be honest and if I could go back and do it again I would choose a nice lazy V8. If you do pick the 24v or YB feel free to PM me with any questions you have.

At 300 brake both engines are fairly stressfree, but if one blows up it costs peanuts to replace where as with the other one you will need to sell some kidneys, remortgaged the house, speak to the bank manager, etc to get it replaced because you'll simply want to have it with at least 500 bhp as only peasants drive yb poweed cars with anything less

Been there with both and the weight advantage the yb gives over the boa is very significant, at least in the sierra it is.

 

At least the last few posts spoke some sense...

Some right crap here, from both sides of the table.

The YB isn't the fantastic engine you all make it out to be. Very capable for it's day, but miles out of date, and the parts are very very over priced. And not for the reason someone gave that they're amazing, but simply because the cars have a massive hype surrounding them and are very collectable, which pushes the price of parts up. It is easier to get power from the YB than from the BOA/B, but that's just because of years upon years of development. The car was modified instantly as it was used in competition, so this soon filtered into the tuning industry, and it's gone from there.

The V6 is far far cheaper to fit, and is a great budget conversion if you want c.200bhp without getting raped by 'Cosworth Tax'. Nothing wrong with the engine, it's strong, torquey and reliable. Nothing light or clever about it, but it is old hat these days, so it's no surprise. I wouldn't say it's better or worse than the YB, they're totally different engines for a different purpose. But you can't say it's shit and can't be tuned. Of course it can. But it was never really developed for competition like the YB was, so why would there be loads of upgrades around for it? Most silohuette formula cars were restricted to smaller engines, so there was never any need to develop it. Doesn't make it shit, just means it hasn't had the engineers pouring over it for years like the YB has.

If the guy had to choose between the two, based on the fact he isn't planning to do the work himself, I'd go for the YB. Initial expense of buying the engine is higher, but you can bolt it it, and with basic mods, get decent power. But paying someone to fit the V6, then having to pay endless hours of labour to turbocharge it would soon see you spending more money I would think. It's all well and good if you can do it in your shed, but a lot of people can't, and that will make a BIG difference to final cost.

At the end of the day though, both engines are 20 years out of date, and there are far better ones out there if you look around. Just depends if you want to stick with a Ford lump so you can raid the parts bin for most of the parts to fit it, or get creative to fit something different.

 

whats the difference in weight then?

 

what engine has the motor got in it at the mo?

if its got a pinto, the yb will fit in, if its a v6 get the 24valver. dont forget both will need injection systems and the wiring plumbing in tho

as above, the boa is cheapest if you are just after 200bhp and not much stress or cosworth tax

v6 has timing tensioner issues and the big ends wear out, but thats about it really. what about the YB?

is there room for intercoolers and the associated pipework as well in your install?

 

what goes wrong with a properly built and maintained YB?

pretty bullet proof in my experience.

most problems cause by poor maintinence or tuning or OLD and knackered sensors and ancillaries or wiring looms going wrong if you ask me.
