Hi again, sorry for the delayed response, but here are some photos of the manifold and the carb, to me it looks like a standard-ish LCB manifold but it's kind of hard to tell from the photos?

 

Any other recommended upgrades that won't stress my engine too much but give a little edge? :P :)

One of the easiest performance upgrades, if it's been a while since the last one, would be to get the car over to a rolling road that knows minis, and have your mixture adjusted. It sounds like your car has various mods done, and if the previous owner didn't have it tuned, you'll get a gain there. Also, it will generally be healthier for your engine to run a good mixture.

 

If you do change the exhaust or other parts, do the rolling road AFTER those.

If you don't have a stub stack in your cone filter, you could see a slight improvement from that. A good service and a tune up is always a good idea. Your filter looks like it could do with a clean too

No disrespect Timmy but that Stub stack wouldn't be as good as the MED version: http://www.med-engin...med-stub-stacks which is the best design according to the yellow bible; I really didn't like all the drillings on the face so I went for the Pipercross version: https://www.somerfor...oducts_id=14708  which made a noticeable difference.

So those Med stubs simply screw onto the carb intake between carb and filter?

The minispares one was just an example, no offence taken haha! The holes drilled in they face line up with the air bleed holes from memory?

They all should mount like this:

Ah cool, I don't have a stub stack in my filter at the moment :) It seems to be running well but like recommended I think I should go for a rolling road setup soon :)

 

I'm considering getting electronic ignition just to help it through winter, I've seen on TMF that the Pentonix one is recommended, is this an easy fit? Does it require any wiring/soldering?

 

I think I'll have a think about the manifold... is I was to replace the exhaust manifold and the inlet manifold would there be anything else that I would need to get? :) 

 

Thanks for the help guys! Sorry for the million questions!

Unless the currents manifolds are particularly crap, you won't see much improvement by changing them. One of the most important reasons for changing from the original manifold is that the exhaust and inlet are cast as one piece and it causes a lot of heat to be added to the inlet manifold.

Ah I see :) I'll probably leave the manifold for now then and concentrate on other parts :) thanks for the advice :)

Just out of interest aha, in order to fit this would I need to remove the carb assembly or can the manifold be fed from underneath the car if it was on a ramp?

Will the longer pipercross stub stack from somerfield minis fit under the 1.5" air filter? Also are there hole for the screws to go into or does it just kind of 'slot in'? Sorry for my lack of knowledge aha I haven't fitted one since I got the air filter awhile back but I should do just wondering if the pipercross and the MED one have any advantages over each other? :)

Which 1.5" filter?  There are so many...

 

 The Pipercross stack that Somerford sell won't go under the K&N cone filter if that's what you mean.

Not sure on that.  MED do an ITG filter to fit though.
