Im planning to do a stage 3 head port and polish. Is it worth it?
Are the differences noticeable?
there is no such thing as a stage 3 unless it is a mass produced profile used to describe the final flow increase (not even as a description on the port shapes).
Port matching, and a good enlargement with smoothing out the lines will increase the flow, which will definitely help the engine breath. I can't say how noticeable it would be buy itself, as you will only improve to the limits of the next restriction.
Stage 3 port polish means doing the head, combustion chamber, exhaust manifold. I think thats all.
And i searched stage 3 port polish in the internet. It exists. But thank you :)
You need have a goog header and a CAI I recomended and AEM CAI, that increments the torque, but you ned a good specialist to do it and perform the values in a 3 or 6 angles, if the work are bad you will risk a lot your engine, a bad work can make loss compression and oil loss, be carefull, and search a bank flow to do it...
The torke feels impressionant, you donīt have to push to much the acelerator to a good response, buth the car at low revs save fuel, but y you demand more for the engine, the gas increase a lot...
Do you have to boring your thorttlebody, but, don exceed more than 2mm of diámeter....
your exahust or cat back line donīt have to exced from 2" to donīt lose the back pressure, and damage the torque and power in low revs, the gas octanes you most increse too,depending the engine time tune, excuse my bad english...
Yeah, im getting all those stuff very soon. The workshop im going is very reputable. Got alot of good feedbacks and they have a flow bench to do it right. So i trust them to do it good. Do i really need to increase the gas octane? And do i need like a fuel regulator or upgrade the injectors?
Not because the flow dont increase too much, I have in other engine that mod witha FPR an stock injector, the flow gives the fpr, and I do not move, to much, only a 2% to the stock fuel flow, because when increase the mix in un 5% the mix are too rich, and the car drowns with te gas, and you nid it an wideband metter...Quote:

Consider and ECU tune...

Wich engine have?...
I actually would like to know as well which engine you have. Also are you planning on dyno-ing it? I'd like to see the results, give me a good idea how much gm has underrated these engines; they already have a history of that with the 60 degree V6. I may have a source in the states that I could try and persuade to work on these engines but I haven't talked to him yet.
I have the 1.5 E-tech engine, 2004. Yess, im planning to dyno before and after the port polish. We'll see the difference.
I have been asking alot of people that has done this and their response are positive :)
this is from my past car P&P job...

How was the difference?
