nova gsi

[steviegsi]

Hi
Anyone no if an exhaust manifold from a gsi wood fit my 1992 nova 1.2i?

[Riggy]

YES
but you would have to fit the rest of the system as the gsi is a 4-2-1 unlike the 1.2i which is 4-1

you could fit the gsi system (with or without cat) but cat will be neded for mot

Hi.Got a sportex cat back system yesterday and it supposedly fits a gsi too , so surely if i got a manifold and cat from a gsi it wood work ok?

[Chris]

that would fit but would need the front part of the GSi system to mate upto the manifold

So how many sections are ther that i wood need?
the manifold the cat and???

[Mike]

x3 sectoins altogether.

top and bottom half of the manifold and the CAT box/pipe. the CAT aint gonna be cheap tho unless you get it from a scrappy :|

[Chris]

to a standard nova system there is:-

Manifold (bit that bolts to head)
Down pipe (bit that goes from manifold and finishes at back of engine bay)
Front section ( this is cat or just normal zorst, goes up to just after handbrake handle)
Rear section (goes over beam)
Back box

Cheers. That was my plan any way. Because if i get it all , the cat will be comin off after m.o.t , and a cat replacement pipe put in. Anyone no if it makes the car much quicker?

yer get a GSI manifold downpipe and cat (needs to be from a C16SE so it has the lambda port) then fit the sportex cat back

it revs freer without the cat and with the 4-2-1 but u need to swap out the cam for the greatest benefits - a GTE/gsi one would be the best

i thought that no nova was listed as needing a cat for the MOT, therefor you can do away with the cat completley and safely ?

[Nick]

all cars 93 > are supposed to be cat equipped (i.e. injection models). I've heard that novas aren't listed on the guidelines for cars that require a cat? Don't know how valid that is though.

[Aragorn]

there is no fancy regulation that says novas dont need cats

ANY engine built after august 1992 REQUIRES a cat for the mot test

so if your 1993 nova has a 91 engine u dont need a cat
if your 93 nova has a 93 engine u do need a cat

similarly if u stick a 91 nova sr engine into a R reg astra3 u DONT need a cat

the regs go on which is older out of the car and the engine

my 92 k passed its test without a CAT on it

[Aragorn]

my bros nova passed an mot with fibreglass all round the inner wings and holes all over it

just because it passed an mot doesnt mean it should have...

[NOVA_JONO]

My 1993, k reg, failed MOT on emissions because it had beed de-catted. :x , so i had to have a cat put on. :roll:
