First and foremost Ro sunny makes custom manifolds which will flow better again than these. But for one of my pulsars i have just had a standard manifold properly ported by a lad who dose headwork inc port n polish very well known with many years experiance also now dose alot of kit cars really knows his stuff done many one off custom conversions and was building engines for a few big companies who claimed to be offering engine builds they would send them to him. I just said i would mention he can port standard manifols now this is something you can do your self  just very time consuming but i am sure he flow tested mine so better than me attacking it with my dremel. I plan to send mine to get zircotec heat coated but its all money just thought i would mention this if anyone is interested i could ask for group buy price. I am sure he mentioned £80 so its not cheap but like i say he is very skilled and its time consuming.

The manifold is NOT masivly restrictive its more the elbow but every little helps and this will make a difference
THIS is not a forsale thread just trying to help people with things and put something back into a club i take alot of info advice etc from but if anyone is interested just ask if anything happens i will contribute fees to the club etc

I spoke to zirotec regarding ceramic coating on thursday and was quoted £180 for a standard manifold just to give you an idea mate
I also run a ported standard manifold

Bloody hell knew it was not cheap but thats a fair bit but i am great beliver in you get what you pay for. might wait and do it on my other R system. Suppose its long lasting and by the time you heat wrap and things. Thanks for the info

That was my thought haha 180 is alot i think but you are correct it is prob worth it, im still debating wether to get mine done or not.

I'm getting mine coated soon it's already been ported, Going to get the heat shields and new 3" elbow done too.

I think £80 sounds like a good price for a pro job,it took me a bloody age to do mine.

I did not do this and it would obviosly cost more to do but there is a large recess in the side of the manifold that can be cast welded up and then ground out from the inside to improve it even more.

this sounds interesting !
where is your friend based ?
i have a cracked mani (one of those old 2fast2cool jobbies) so was planning on swapping the original back in !
how much difference does a ported unit make ? is it a noticable difference - or does it depend on other factors - i.e. only better if running higher boost (and things like that) ?

Any mod that gets more air in  and gasses out faster  is money well spent in my opinion scotland but i have one spare but as said see if theres any interest i can pay towards the club and sell it/them 

I got two done just because i was up there and he says one was bigger at block end and other one  at the other both were standard manifolds 

It surly makes some difference and coupled with a elbow should be a good combo

yep as johnny said I did mine around 2 years ago now and its a lot of work and time plus all the dremmel bits you eat through.
never had mine flowed (that would be difficult to do as all 4 branches flow into one collector so cant see how you can flow it properly tbh unlike a head which can be done with valves closed on one cylinder at a time.

but even so £80 is cheap and saves 4-6 boring hours with a dremmel and countless bits lol

heres the one I did earlier which was fitted to my car and now glenn is the proud owner of
I opened the ports up on that by just over 1mm and matched it to the head

Did you not try using carbide bits bob they are not expensive....?

cant remember what I used now Leighton, no there not dear to buy but I did go through quite a few to do it.
its the time thing mainly as its a monotonous job to try get them all the same size and shape but does improve things significantly especially if the heads ported and you have a freeflow elbow fitted

Carbide bits are what the proffesionals use to port ...
