also i looked at my SPI manifold compared to a standard one. hmm

tally ho!

Is it possibly to dremmel the inlet manifold out and then polish it up? how did you do yours??
 
wicked, i think ill do that when i put on my tricker then. just dremmel as much out as you can or is there a max diameter you can go?
 
Get a new gasket, line it up to the manifold and mark the maximum you can go, then dremel to that. Go as far up the ports as you can but do not leave a step in them, you must make it a smooth transition. Don't worry about polishing it up though, it doesn't need it otherwise fuel and air won't mix properly.
 
If you do dremel it out, theres many things to condiser, like, how wide to go before risking putting a hole in it, the finish it leaves, and if the mating faces are going to be affected in doing so. If you are doing it, you have to get all ports/holes, as close as possible to being symetrical to each other and leave a slightly rough finish to allow the fuel to not form as droplets (cant think of the right phrase) as polishing will do.

Its possible to do, its just care has to be taken as you can easily end up being down on power rather than up.

I`m not sure if you`ve sorted your clearance problem with your coolant pipe?
But i removed the angled pipe from mine and cut down the block it`s mounted to,
Then refitted the angled pipe.
Hope this helps

slighlty different approach, but acheived the same thing

and a few more pictures (ive not been avoiding working on it, much)

got the 75 head back, been taken to the same spec as my SPI head.

isnt it shiny! :D

had the 75 manifold matched to the head as well

and the mod done as you can see in the previous post.

this of course now means my old GSR prepped head will be for sale soon.

picking up the new custom brake hoses tomorrow (cheers Aaron)

these arrived this morning, addressed to 'Cento Lover' hehe.

stainless steel flexys for the brakes. Fronts, and then the custom rears so i can fit the GT rear calipers.
