Zorst help please.

[NovaLad]

Ok after PM'ing about 4 people and asking people on msn and still don't have a solution to my question i decided to make a thread.

Ok AndyRacer is selling this - http://www.pngclub.com/forum/showthread.php?t=99022&highlight=ANDYRACER

IIRC it came off a 1.3.

What i want to know is will it go straight onto my car or would i need diff manifold/downpipe or welding done etc...

Give me my options if i was to buy it please.

My car is a MK2 1.2 merit Carb.

Thanks.

[Jack]

I vote: Fit.

[NovaLad]

Is that a guess vote or a IT WILL?

I have been told off Burgo that the 1.3 came with 2 downpipes or something and by others that it is same as 1.2 and will bolt straight on.

Burgo also suggested something about welding it onto the 1.2 flange or something.

[NovaLad]

lmao, i love how you dont read my replies properly

Explain lol

[CoolTiger]

like is said on msn im 90% sure it will fit but you would need 1.3 downpipes

[meritlover]

i have just got your PM so please dont be offended by my lack of reply. i have been working very hard this evening.

[mowgli]

Right, first off IT IS CALLED AN EXHAUST!!!!!!

Secondly, a 1.2 has a 4 into 1 manifold & a single downpipe.
a 1.3 has a 4 into 2 manifold & a 2 into 1 downpipe.
from there on, the systems are the same........

so to fit the ashley EXHAUST i suggest a quick call to ashleys to see if it will fit the std 1.3 exhaust downpipe or if it needs a complete swap.
if it will fit the std downpipe, then it will fit the 1.2 downpipe as well.


I think a zorst is a polish sausage

I was always under the impression that the 1.2-1.3 and 1.4 downpipe were all the same, and the sri, gsi and gte had a different maifold set-up. :confused:

[Rexy]

Has nobody thought about the exhaust port size yet, 1.3 sr's have round ports where as the 1.2 will be slighlty smaller. There will be a step for the exhaust gasses.

IIRC the 1300 exhaust manifold fits the 1300 and the 1600se as they share the same port size.

I've never played with the 1.2 cylinder head, best thing is to ask andy if you can try it. If it works it works if not..... Say your sorry for wasteing his time, or sell it on.

Jobs a good un'

Best edit this as i was under the impression it was for a Exhaust manifold,. not an exhaust system.

[mowgli]

the actual systems from the downpipe joint back are the same on 1.2 & 1.3.
the 1.2 originally had a one piece system all the way from the manifold to the backbox, so when it broke you had to buy the lot..
the 1.3 manifold & downpipe was a straight swap, & allegedly gave a couple of hp.
I don't know about the 1.4 carb, but I thought the port shapes were different, or is that only the inlets????

Then the 1.4i & 1.6i are identical, but the backbox trims changed.

my longterm project (cos I'm too skint) mk1 has a gte system & a std 1.0 backbox because I was going for the bog standard look & it fitted perfectly.
As far as I know, the factory backboxes are the same internally

[mowgli]

the 1.2 carb & 1.3 heads are visually identical.

[Rexy]

cheers mowgli, i knew that the 1400 sr was totally different but i wasnt too sure on the 1.2/1/3 head.

As saying ive never ever playing with baby engines.

[Rexy]

and i was about to say yes the exhaust system will fit his 1.2

[silvertornado_sr]

depends if its a catconverter system aswell the connections on exhaust are diferent on cat one if that helps

[Jack]

I thought all the exhaust flanges (lol flange) on the manifold/downpipe were in the same place, i.e. where they connect to the rest of the exhaust?

[craig green]

Seeing as its off a mk1 & you want it for a mk2. I'd say dont bother.

The tailpipe will exit at a gay angle from the rear bumper.

[ANDYRACER]

Craig i bought the wrong one, its a mk2 system :thumb:

[NovaLad]

So what people are saying is that the manifolds are different but the downpipes are the same so it will fit?

I can't belive no one seems 100% sure lol!

[loggyboy]

Heres the Gospel:

1.2 has a 4-1 manifold, that ends pointing down. The downpipe joins to this but its also the front pipe (its a one piece down/front pipe), that then goes allthe way to the middle box section.

its looks like this:

The 1.3 and 1.4 carbs (any 1.3 models and 1.4SR) have a 4-2 manifold that ends pointing down. The downpipe joins to this and goes from 2-1 just under the sump. This then joins to the front pipe (where is where the aftermarket exhaust will start).

it looks like this :

http://bodyshopwarehouse.co.uk/images/files/08821500.gif

The 1.4 and 1.6 MPi (sri gsi gte) systems use a similar set up but the 2-1 downpipe finishes at a different angle.

1.4spi and 1.2spi use a similar setup to the 1.2 carb but the front/down pipe is shorter as it meets the CAT.


So the simple answer is NO the 1.3 exhaust will not fit your 1.2 UNLESS you change the manifold and down pipe to an 1.3 setup (or you fit an aftermarket 4-1 manifold for a 1.3).

[DAN-F]

right ive done this loads of times ive never seen a 1.3 with a single downpipe thy all had twin downpipes from the manifold so you will have to fit a manifold and downpipe from either a 1.3/1.4 or 1.6 (not a gsi though theyre different cos of the cat) to make it fit from. the downpipe back theyre all the same

you won't ever see a single downpipe 1.3 cos it was only fitted on the 1.2.........

[mowgli]

novalad, ask your uncle, cos he will be fitting it!!!

[DAN-F]

you won't ever see a single downpipe 1.3 cos it was only fitted on the 1.2.........
which is exactly what i said,

[Adam]

And to now end this thread.
All 8v OHC exhaust ports are IDENTICAL. A 1.2 manifold will fit and match a gte 1.6 head....

And as Loggy said,
To fit a 1.3sr system onto your 1.2 carb engine, you need a 1.3/1.4SR exhaust manifold and downpipe. Fit that and the system will then bolt right up.
1.3/1.4 mani/downpipes are identical.

[mikey14sr]

1. Exactly as Loggy posted

2. As Adam said, exhaust manifold fitment to the head is identical across the smallblock 8v ohc range, I've had a 1.3 manifold and downpipe on a 1.2carb and both a 1.4carb and mpi head, although the size of the port openings on the manifold were ridiculously small compared with genuine gaskets for all three heads.

[mowgli]

the size of the port openings on the manifold were ridiculously small compared with genuine gaskets for all three heads.

thats because if the gaskets were the same size as the ports, the hot gases would burn them out, so they are larger to get them out of the way.......

[mikey14sr]

mmm, wasn't showing any signs of the gasket burning away after 5000 miles of pretty heavy abuse though, in fact the only real trouble with it at that point was the increased wear on the valves and guides due to them having done god-knows how many miles and suddenly being bashed further than ever before by the 285 camshaft!

[mowgli]

the genuine gaskets were designed for about 250000miles of use. its the manifold copper nuts & how to get them on & off that really annoys me

[mikey14sr]

me too, I ended up replacing all but 2 of the exhaust studs with stainless bolts instead, seing as the studs allways came out before the nuts moved.
