Hi There,

Just out of curiosity, is this an engine ( 2.9 V6 12v ) which responds well to tuning?
And if so, what could be done then?
I know that swapping it for a 2.9 V6 24v BOB or BAO would be easier, but that's not what I want ( for now that is)

Any advice welcome

Grtz

Ginge !

mate tbh the BEST way to work out the BEST value for money is to see what cars have these engines

they aint that responsive for tuning hence people stick other engines in stuff

Hi B, didn't know you were into the Cologne V6 engines. In what car you want to use it?

the v6 cossie engine is superior in almost every way, more powerful and has more tuning potential (as long as you stick with the right tuner who knows what their doing)

You can get about 170 bhp out of them with a chip, filter and exhaust and some claim to have had nearly 200 bhp with a new cam as well. However, the best bet is to either drop a 24v BOA in (200 bhp as standard) or fit a turbo technics twin turbo kit which uses 2 x T2 turbos. There were different level kits but the most common is the 225 bhp one and I dont think this required a head swap or anything else internal - you can just bolt it up. These kits produce a lot of torque and are pretty quick - but expect shite fuel economy!

you can get an extra 20bhp by fitting a uprated fuel pressure reg (Jonny Bs old red xr4x4 had this) and made 224bhp on RR IIRC....was by no means a slow car when I gave it a bashing (sorry Jonny ) once or twice.

been there, done that, lots of potential if you spend the money

n/a engines goes a little something like this

k+n filters for starters, the ones that replace the airbox
exhaust, full system with manifolds, the power engineering ones were probably the best all round options there were but others did do them, cheesemans, but they were about twice the price
cam with solid lifters, but this is an engine out job and you'll need to lift the heads which means:
head work, you really do need to get some headwork in there as the heads are a bit pap

considering you can do the cossie swap, if you know what you are doing, for less than the price of getting the head sorted, it's a lot of money to make less power and have worse ecomony

if you want to go the forced induction route:

pistons, rods and headwork are all required if you want to go above the 200 bhp mark
and you would need to find a tt kit in the first place to get it all to work
plus you will need the minimum of aftermaker manegement to get it all up and running as these engines really don't like running lean and will melt at the drop of a het when they do running regulation pistons

the easiest method to gain more power is to ditch the viscous fan and fit twinky sierra leccy fans in it's place

and the other thing is that these engines don't make a whole heap of power after they hit around 6k prm so it's all about the torque

bolt in a cossie clutch and cover plate to deal with that, even the standard one will do as long as it's for the 4wd cars as they used the same geabox

there is nothing like the turbo rush on the V6, it's immense and the power is there from as soon as you put your foot down, the torque curve is like a wall from around 1900 rpm when mine was making full boost, and 90% of my torque was available from 1400 rpm all the way till 5600 rpm on the 12V engine

one more thing though, my 12V tt engine made 351 brake and 392 ft/lb of torque at 12 or 13 psi, but did 4 mpg when i was hustling, and the trip computer regulalry read 1 mpg when the foot was down, in additio to not getting mroe than about 160 mpiles to a tank, regardless of how i drove it

i did 22 miles in half a tank once

Jimboxr4x4

They are very underated engines but all the 24v's i've seen have had oil leak problems. They all tend to drop oil really badly after a few years from various locations.

Jim Galbally

if you can get a twin turbo kit for a couple of hundred, then do this.

else, put the 24v in

ive done both, the 24v was the better option

Jimboxr4x4

Dojj, did you ever get your car back from Top Boss or are you still waiting. Wasn't it up there for like 3 years or something?

Jim Galbally

dojjs car was in top boss back before we even met jimbo. that was what, 5 years ago?

mark

would could get 200 bhp from the 12v f you put time and money into it
my old one had 189 bhp with head work filters and zorst im sure i could of got more out of it with a cam but thats life lol

just NOS it ? job done

foreigneRS

best place for that engine is where it was designed to be - on the end of a chain hanging from a large boat

ECOS95

I'm sure I read that somewhere, one of the top bods at Ford said it was all it was good for.Lol.

Jimboxr4x4

Its not still there?

tabetha

I agree but a bit heavy for a boat anchor.
I had a overbored, cammed, modded head 2.8 cologne V6, frankly it was an embarrasment, after going from a 2.1pinto with modded head(little mod) cam and 32/36 carb that was vastly faster, and automatic.
Anyway I gave mine 2000 miles to bed in, tuned etc and it was still crap, ran perfect just did not make the power, I have never ever seen one single 2.8i make what ford claim either, nowhere near it.
It was so good I scrapped the car with a 2000 mile new engine and gearbox in it, just lost all faith in it.
IMO if you are going to replace at some point do it sooner, but personally I wouldn't bother with ford V6.

Jimboxr4x4

The 2.8 is pretty rubbish and like tabs says it rarely makes anywhere near the quoted 150bhp. The 2.9 is much better and usually does make 150 or even a bit more, even on tired engines. Check out the couple of rolling road sessions in the magazines featuring xr4x4s and the 2.9s always did well.

Even so, its still nowhere near as good as a 24v.

Jimboxr4x4

Dojj, come on whats the answer? Top Boss haven't still got it have they? I remember it going up there years ago.

Yes they do suffer from leaks if not looked after properly, like the cam cover gaskets, theyre bonded to the rockers and are no longer available from fords (havent been for a loooooooong time either) so they get siliconed up and being a V6 they leak down the centre of the engine and it makes its way everywhere.... If you built one properly and took care to seal it all properly it'd be fine....get one with a leak and your just going to have to live with it

Hi Roy,

Not in my Estate for sure
Just checking possibilities, but the main project stays the 2.0 silvertop replacement for the Estate.
The V6 is something for the future

Thanks to all for their replys.

Keep it original then. Though turbocharging sounds great, hence the fuel economy :-(

i beg to differ with dojj about needing pistons and rods over 200hp.
my white one(that i used to race dojj with at the revs track days) eventually made 258hp out of a standard tt225 conversion,which as far as i know just had slightly lowered compression(done with the cylinder heads) and 2 extra injectors.
that was enough for 1.8sec 60ft's and 13.5 second 1/4,s. it would even light all four tyres up off the line,but due to crap gearing would only do 140 all out

iTrader: (2)

My daily driver 2.9 XR4x4 made 160bhp on Emeralds rolling road with magnex and K&N's............ probably be 170 on Power Engineerings magic rollers. 24 valve is a much better engine even if you ignore the bhp advantage, the extra mpg alone is worth doing the swap

Mark

dojj

iTrader: (3)

the cars been back for a few months now, but i've not got round to doing anything with it to be honest

the head work is the basis for the 225 conversions, the 200 ones were for the single turbo 2.8's with no extra bits required
the 280 ones on the later 2.9's were much more invovled

SillyFezzaMk1

iTrader: (1)

what is left to do? I thought you'd get it back finished?

Dan

dojj

iTrader: (3)

it was up and running, just needed mapping and bodywork

but i can't map it as i can't sort the prolem with the brakes out
and i can't sort that out until i've got the wheels off
and i can't get them off until i drill the lockers off
and then i want to fit the 355's to the front and relegate the 330's the rear
and then i want to get rid of teh leccy seats and bolt in some cossie leathers instead
and then i want to do loads of other stuff to it as well while i've got it in bits
and then i can get it back to fitz to get the bodywork sorted

it's probably only a relay or semthing silly that's fucked the abs up as the pump is running all the time, but i want to make it look good and tidy

besdies, talking baout leaks, the return from one fo the turbo's is weeping so i've got to figure out how i'm going to get that sorted by not undoing the whole crossmember to reach it

and then i've also got the problem of my rs2 being parked directly infront of the garage so i can't actually open the door to move the sierra out
and both cars have now got flat batterys

and that's before i tell the mrs i want to work on the car bcause she's already said i've wasted too much time during the paternity leave and didn't do the wallpapering until the last day

and i've still got the other garage to sort out as well because the old man wants to put a bed in there
for the guy who's currently painting the house
due to that fact that the old man is paying him in food and lodgings
which means the st lump has been relegating to living under a few sheets of tarpaulin outside
while i get that ready to take to bits

and then i've got the other spare sierra that i'm going to drop that lump into
once i figure out how to get the bastard gearbox off

and before i do all that, i've still got to sort out ALL the bumperes i've got that are cluttering up the place (% of them)
plus the 3 wings
plus the 2.5 engines that are in bits around the garage
all carefully being manouvered around teh pool table
so that i won't have to shell out to get it recovered again

and while this is being juggled, the old man says "can tyou get me one of the bit pots that i've put into the coke fridge, seeing as i've turned it off as it draws too much electricity and i'm a cheapskate, even though you are paying the bills"

so it's a bit at the moment

and don't even think about mentioning the newborn because the wife is still with me about it

Jimboxr4x4

There is nothing you can do to stop them leaking from the gaskets. You can get replacement gaskets as barry at XR4i spares got a load made up and was selling them for about Ł80. I changed them recently on my brothers one but they have leaks all over the place, not just the rocker covers.

ive had both the turbo technics twin kit and 2 24v`s and id say the turbo was better

i did nearly 40k in mine and kicked its arse everytime it was out and ever let me down

I never said it was lightning, and obviously if you've got or are used to 400bhp cars its going to be slow....It was about as quick as a std 3dr I had.

I'd bite your arm off if I still had a 12v XR4x4. Thats a good price for a complete kit.

of course he can - he is indian and lives in southall = anything goes

iTrader: (3)

damn straight mate, in fact, the only reason he's got a place to kip in the garage is that when he's finished drinking he can go directly to bed and, in the morning, the old man came open the door and tell him he's paying him to work, not to sleep

as for "employee" it's not as if the old mans paying his ni contributions and tax is it

I have 2.8 Cologne V6 out of an XR4i... I know its not the best possible tuning platform but I am seeking few more bhp before the engine will be put into a -73 Taunus as the old engine is dying. 2.9 and 4.0 V6's weren't really options, and neither forced induction as the car won't pass MOT then.

I already have steel exhaust manifolds for the engine, and plan to make stainless steel exhaust system for it. Carb will probably be 38/38 Weber and I reckon it could use some head porting as I've seen stock Cologne heads and they were horrific. When it comes to cam choice, would Pipercams 270 do the job? Im after nice fast road cam with lots of torque so no need to make ultimate high rpm hp.

With ported head, sorted exhaust good carb and nice cam, would I see power somewhere near 180 bhp and 250 nm? That would be enough for 1000 kg car as its just a cruiser not meant to do any kind of racing.
