can any1 tell me the power figures of a standard sierra 2ltr dohc

 

125bhp I think.

 

slow as hell then lol,, pickin up a mint sapp cossie rep later was just wonderin wat too expect,,, got a granada cosworth engine sittin tho

 

then it's not going to be 125 brake then is it

if it's still got the 2.0 diff in it it's going to get to it's top end really really quick, but top out at around the 135mph mark

 

uve lost me????? its a 2ltr dohc,,,, i have a granada cos engine sittin at home whichwill be goinin

 

aha, now you aren't speaking scottish i can understand better

normal dohc 8 valve injection sierra will put out 125 brake
the one that comes with the catalytic converter, puts out 120 brake and has totlay different wiring
the carb'd version is very rare and very shit so don't bother with it

when putting your cossie lump in, use V6 2.9 front springs and upgrade the stoppers at the same time, 2wd discs and spacer brackets will do the job but you might as well get a big brake kit if you want to go the whole hog or get some 2wd standard hubs/suspension and stoppers if you want to wait a bit

you'll also need a rwd mt75 box that will fit the v6, not a lot around so look at the options for that (my way was to swap the bellhousing from the V6 engine'd 2.9 xr4x4 with input shaft onto the rest of the rwd mt75 box and be done with it, and everyone else followed afterwards)
if you get a 2.9 xr4x4 you can also swap the diff over, it'll be taller geared but not quite a direct fitment, so just swap over the whoel xr rear beam and get the rear arb to go along with it

while the box is apart for the swap, also consider the longer 5th gear mod, about Ł200 in parts from ford but worth the effort (another idea everyoens taken for granted yet first worked out, fitted and done by me and tony, mob)

you will also need the fuel pipes form the V6 as they are on the other side of the engien bay

you can also use the flywheel and pedal box from the V6 to mount a cossie clutch (with correct realease bearing) but use new flywheel bolts as the auto ones form the granada are too short for the manual flywheel, get it lightened at the same time and it will want to rev it's tits off

mark 24v wiring can sort you out with a plug and play loom and job jobbed

jus tmake sure that the rev counter works and you don't go beyond the redline as they tend to fall apart very quickly afterwards

 

but 2.0litre dohcs have 175lb/ft of torque according to the haynes manual thanks largely to the very heavy rotating mass of the bottom end, eg the massive flywheel!
slow to rev, hard to stall..

 

the fucking 2.9 V6 has 172 lb/ft, how is the little 2.0 4 pot going to have more

it's got about 130 lb/ft, but seems more due to the really short gearing

 

I had one of these engines in my old sierra.It was a bloody good engine i thought.Ims ure they are about 125bhp.I took the cat out of mine and fitted a cone air filter to make it go a bit better.

 

it was late, sorry for shouting and mocking

 

yea it certainly seems ok,, wont be there for long tho,, cant wait to get ma hands dirty!!!"!!!

 

im doing basically the same m8 but im putting a 2 liter pinto in better to ture up and you can run them on carbs if ya wona my mates have dohcs and they say there 165bhp but i really dont think it is

na wouldnt say so,, the one thats in righ now is a dohc,, replacing it with a cossie, the car its self is a cosworth but the engine poped n the guy b4 put the 2ltr dohc in,, just a case of replacing the engine, loom and bellhousing ( i fink )

 

yh i was thinking the same i dont think you can tune them as much enless you spend tons of cash on em but iv herd they aint all that anyway but they do have a alright top end iv defo been in 1 that went 135mph and im sure he only had a few mods

but good luck with your saff im currently working on mine

lookin good man,, ill take some pics and post them on here 2moz

 

sweet mate

and thanks

 

Heres a power graph for the 2.0 engine. God knows where I got it from though, Its in newtons a kilawatts so if anyone would like to convert to lbs/ft and bhp, be my guest lol

 

g

best one i've seen made 142 at the flywheel

considering that they red line at about 125 in 5th i reckon his speedo was telling porkies

 

113 bhp

 

this was mine in a 4x4 estate..............

 

a few from the sierra club rolling road day..............

137bhp @5893 rpm
130bhp @5994 rpm
130bhp @5666 rpm
142bhp @5780 rpm
131bhp @5700 rpm

the higher two were running four branch manifolds and chips, while there was virtually no difference between just cone filters and standard..........

 

thats wierd my 1.6 pinto on a carb goes 102mph and that wernt red lining lol but not saying you a liar just seemed very slow

 

it's about the power and the gearing overcoming the drag

the pinto has a higher geared set up than the dohc and less power, so it's going to be slower

on the other hand, i had less power than my mates car, about 10% less, but due to my gearing, i was able to go past him on the straights

 

had 130 on the motorway bout an hour ago !!!!!! is it fair to say theres no right answer to this then??

 

so its solved so get a 2 liter dohc and put a t9 box on wicked

 

seemenly the sierra is quiet rare because its 4 wheel drive ??? av always liked fords but never been that clued up to know if this is true, its a magenta sierra sapphire with 4x4

 

4x4 sapphires that are not cosworths are quite rare yes

 

the 4x4 sapphire and estates are badged as ghias............ not exactle rare but not what i would call common either tbh.............

 

considering that at 6000 rpm in 5th it does 127 mph means that your speedo is WAY WAY over reading

if you were to bolt in the 24V engine into something with the 3.62 diff's then it would do 143 mph

if you were to use the type 9 box you would gain an extra 2 mph at the top end

 

i was flat out in 5th,, maybe a tad out
