Right lads and ladies, I need your help once again....basically, has anyone got any useful tips on fitting my JP zorst from my 1.3 Antibes to my new GTE???

I knew from past knowledge that it wouldn't fit as the down-pipe and manifold are different, but totally forgot that very important piece of information, and ended up wasting 5 hours this afternoon with my Dad, trying to swap the JP from the Antibes to the GTE, and the GTE zorst to the Antibes! It was only when I came to bolt up the front sprung clamp that my memory came back...doh! :O

In the process, we had to cut off the standard GTE back box, cost it just wouldn't shift, so now 'cos the JP didn't fit the GTE, I'm left with the standard GTE centre section and without a back box!
It's a bugger, 'cos I can't use it now till I get sorted with a new Back box or what ever I end up doing!
I was even considering repairing my old Peco BB2 back box and put that on with the GTE standard centre section :O Noooooooo :O

The JP's back on the Antibes for now, but I really want to keep it for the GTE, so need a way to fit it.

This is what I'd thought about doing.........basically, the only difference in the zorst is the angle of the front part of the centre section, where it angles to meet up with the sprung joint on the down-pipes. I've thought about cutting off the end of the standard GTE centre section, as well as cutting of the end of the JP, and fastening the two together.....I recon this will be easy 'cos the JP is large enough for the standard GTE zorst to slide inside, and it's quite a tight fit. All I'd need to do then would be to add another clamp to hold the joint securely.

But, I know that you can buy sections of exhaust to combine together to make your own custom system....like the jetex parts as seen in the demontweeks catalogue, but are they expensive?? Would they be any better than my idea above??

I don't want to go and chop the end of my JP off and risk bodging it though...not good....so don't know whether to risk trying it or not. I could of course contact JP to mod it for me, but that would be loads of money I recon :( (of which I have very little at the mo!), plus don't they have a 2 to 3 months waiting list or something?

The other option is to forget about the JP ( :( ) and advertise for a second-hand Magnex or similar.....I really want a stainless 'cos I'm planning on keeping the GTE for the next couple of years at least, and making it a long term project.....Valver in the future :)

manifold will fit either
downpipe os totally different
middle pipe is different as it has an extra box and goes direct to backbox.
dunno if backbox is same?
cant u just swop the whole thing over excelt for the manifold?
i used a full sr system on a gte engine, worked fine.
Got a GTE+sr manifold+downpipe in the garage i think!

Antibes will have single manifold and down pipe gte will have double

where does the jp join the std system?

16v Nova - Toolkit, Trouble, Points and great expence all come as standard :)

e reg shell almost gone!!

Ste.....mines got a 1.3 SR engine in it, including the SR manifold and "twin" down pipes.

The JP joins under the back of the engine in the normal place for an SR.

The GTE joint is in the same place, but at a different angle, hence the JP doesn't line up.

I thought about fitting an SR manifold and down pipes to the GTE, but the manifold on the GTE looks like a much better design for performance.....it's a totally different shape and looks much better for flow, so thought that fitting an SR manifold/down pipes might reduce performance :(

I don't think that my current down pipes from the Antibes would fit the GTE manifold, as the GTE manifold joint is lower down....also, the GTE down pipes are quite a bit larger in diameter to those on the SR item.

I think what I'll have to do for now is just try and get a decent back box for the GTE and connect that to the standard GTE centre section.

I'll then re-fit my old Peco system to the Antibes to sell it, and keep the JP until I have time to try and fit it. I can't nick any of the zorst off of the Antibes, 'cos then that'd be left without a zorst!

Any more ideas would be useful though guys ;)

P.S. Mike....I'll let you know how I go ;)
Dicko......what zorst is it that you've got? Where are you? I might even be interested in a standard GTE back box for now, just to get it on the road!

Cheers lads :)
