Janspeed Monifold

[beefio]

Anyone have experience of this Janspeed Monifold?

Any performance gain to be had when adding to an existing performance back box?

What would be a reasonable price to pay for a used one?

Yes it makes the car feel like it has more low down torque

[beefio]

Is it very noticeable and worth the upgrade?

[Bigfootmgf]

Well my car 1.8mpi combined with exhaust & pipercross air filter now has around 130bhp & 134lbs ft or torque if that helps!

I brought the Janspeed manifold and will attempt to fit it myself and I have a few questions:-

- Will this manifold fit with my existing mk1 cat or will in need to replace with a mk2 cat?

- The manifold and flexi pipe are held together with a round clip which when tightened pulls the 2 sections together...anyone know where I can get one of these as it doesn't come with the one I've brought?

- The down pipe has a hole for what I think is the O2 sensor which isn't present my my earlier F, what's the best way to plug this?

Many thanks

Well, since none of the guys round here who really know Fs have come up with the model-specific answers, I might as well give you my 2p worth: you want to google for exhaust clamps and look at the pictures to find the type you want, then you'll find out what it's called; and for the O2 sensor I think you want to google for an O2 sensor blanking plate/plug. Measure the hole to check you're getting the right size.

It's called a V band clamp
You will need to reroute the O2 sensor wiring down the back of the engine so you can move it to the new location.

Thanks gents

So is there still an O2 sensor on the early F but it's just in a different position that inneed to re-route?

Correct it's in the down pipe at the front of the engine.

Do you have a mk1 or mk2 cat connected to the manifold?

Can it be simply re-routed without the need to extend the wiring?

I have a mk1 cat and bought to suit the car! All went straight on by garage that did it was a tight squeeze tho!

Simple reroute, the loom plug is clipped into a bracket, just unclip it an move it towards the rear of the block.

I spoke to Janspeed and it's a 69mm Manifold Clamp that I need and I brought one on eBay for £4

I also got a new manifold gasket and a rubber hanger just in case. The cat bolts and gasket are new when I recently change the exhaust. Is there anything else that I might need?
