Saxo mk2 decat how do you do it :( HELP

[lewigiepops]

lOOKING FOR THOSE PEOPLE WHO HAVE DECAT THE MARK 2 SAXO VTR I HAVE NO IDEAR AND NEED HELP I HAVE TO LAMBOR SENSORS AND WONT TO FIND OUT HOW TO GET ROUND THIS WITH A MK 1 MANIFOLD AND WILL I HAVE TO MOVE THE OIL FILTER IF SO HOW WOULD I DO THT CHEERS GET BAK TO ME ASAP

[RichM]

You got the black top looking at your 'Cars' info so the cat is under the car and not in the manifold. All you have to do to decat is swap the pipe under the car with a decat pipe.

[lewigiepops]

i have just got a mk 2 vtr 2001 reg

[RichM]

Is it the engine with 1 plug or 3 plug ecu?

[lewigiepops]

3 plug m8 its a mk 2 has cat in the manifold

[RichM]

Theres 2 ways I know. 1. Get a standard manifold from a MK1 and replace your manifold with that, I read that its a direct fit so won't need to relocate the oil filter. 2. Replace it with an after market manifold which most of them, you'll have to relocate the oil filter.

[Add91289]

supersprint mani is a good option as its a quality make and you dont need to move the oil filter

[RichM]

Yeah at a price though lol depends how much he can afford.

[lewigiepops]

with a standard manifold wot will i do with both the lamba sensors

[SteveWC]

no need to talk all in capitals

[chriswoodward]

Sleeve one and plug the other one in as normal, why is no-one answering his question?

[chriswoodward]

No need to post in this thread.

what do you mean by sleeve?

The supersprint and piper manifolds will fit on a mk2 VTR without having to relocate the oil filter.

If you still want the cat then go for a vts cat which is a pipe that fits after the manifold and get a centre section designed for a vts

Hes asking what to do with the two lambda sensors but know one seems to be reading it properly!

Thats why i said on a mk1 manifold you only have one hole for a sensor so sleeve one and plug the other one in! I cant be more simple with the definition of sleeving one of the sensors it is exactly as it sounds.

I was suggesting alternatives as a mk1 manifold is just as restrictive as the mk2 with the cat in so wouldn't be worth the time and effort

I asked what sleeving was but you didnt read my post properly lol - you just edited you post lol

[chriswoodward]

I edited my post 2 minutes before you posted yours! lol:p

What makes you think that?

[VTR_Craig]

What makes you think that?

just what i read

[chriswoodward]

O right well thats wrong mate thats like saying there is no point de-catting a mk1 because the manifold is just as restrictive as a cat. lol

[VTR_Craig]

ok mate

would you agree that a mk1 manifold is much more restrictive than a piper/supersprint manifold

[chriswoodward]

ok mate

Fuck yeah, but the bloke said a bit furthur up that he was using the mk1 mani (i assume for cost reasons)

[DaN90]

obviously not thats why they have have x amount of money spent developing them to be as less restrictive as poss compared to the factory item.

[DaN90]

wouldnt a mk1 downpipe fit??

[yorkie]

the mk1 manifold doe not fit the mk2 engine oil filters in the way i tryed it sunday lol

[ryza]

i tried doing this last night. failed.
the oil filter is in the way because right where the lambda hole is the oil filter is about an inch away from it and there is no way you are going to get that lambda in, so you need to do a mk1 filter conversion :/ i dont quite know how to do this but good luck, and btw it's very akward getting the manifold out because the car just fucks up the radiator.

[RustySkull]

Hmm I De-Cated a MK2 with a MK1 Piper 4-1... didn't have to change the oil filter. Fitted straight on and I cable ties the Sensor what would have been before the cat, to the master Cylinder with a sleeve on it.

[SAM-S44MDS-]

To convert the mk2 filter to the mk1 you need a M20 bolt (M20x1.5 - 37mm long) and a mk1 metal spin on oil filter from Citroen/Peugeot. It will set you back around £10-12. :y:

the 1st sensor i think you should have it in the mani because if not it might run a bit lumpy because that's what actually tells your ecu what to do unlike the 2nd one which just tells you if your cat is fucked or not.

i thought it was a m10 bolt? and i dont suppose you could explain where abouts the mk1 filter goes? becuase it's confusing when i cant really see where it goes :geek: and something else to do with the sensor and not much oil should drain out when u take the mk2 one out should it?

Yeh it does run lumpy, and over fuels a lot lol.

I believe it just has to read clean air.

but i bet as it over fuels u will probably get more unburnt gases and them more pops and bangs :D

That's why I did it lol, Flames like hell too.

People always call me a dick for doing it... But it's a 1.1... I don't really speed so I thought hey let's have some fun lol.

My VTR is set up right though... :fcuk:

[ryza]

haha good fun :p

[chappy10]

craig is correct. any aftermarket part is gunna be better than the standard one. Its like comparing a pot noodle and a steak pie.

[jeffchiz]

omg this thread could have been answered in one reply lol

to fit the manifold you need to buy the mk1 manifold (obviously) lol

and you need to change your oil filter to the mk1 set up with the following parts:
-mk1 oil filter
-oil filter adapter
-M10 trap and screw

and the you screw one of the sensors in to the manifold and screw the second in to this 'sleeve'

thats because some manifolds dont require to change the oil filter ...lol

[danny-boi]

tbh mate just buy the 4-1 as this misses the oil filter while a 4-2-1 hits its

[jayhull22]

mines de cat mate, never had 2 move the oil filter, but i have a 4 branch manifold and down pipe all in 1

[andymacca12]

just get a 4 branch with the 2 lamba points thats what i did :y:

[jeffchiz]

mines de cat mate, never had 2 move the oil filter, but i have a 4 branch manifold and down pipe all in 1

4 branch manifolds on n/a cars always include the downpipe, and as stated some manifolds are designed better than others iirc all 4-1 manifolds fit, the cheaper 4-2-1's such as raceland ones wont miss the filter

seriously the guys question has been answered let the thread die lol

[jseago]

Iv got a mk2 vtr 01 plate, and I de cated mine. I cut the cat out and replaced it with a straight piece of scrap pipe, was really simple and easy, only bad things with that were we had to custom make and weld a piece of metal which at one end was the same size as the old cat so you could bolt it to the manifold and then cut a hole the same size as your exhaust pipe.
