The head will be off to do the valves and springs; so no better time :P

Silvabullit, CHA54 or even Tighe Engineering would know where to go for head porting. Just make sure they flow bench before and after so you know if you gained or lost anything in the process.

when you say that is there a chance i could be going backwards?

what would a reasonable price be to do this work? just the porting? and will polishing make any noticeable difference?

polishing is a waste of time. the basic port shape in the 2ZZ is very good. There are a few 'nasty" spots left over from casting, but radical changes are not needed. on heads like this, you will hardly measure any change in maximum flow. you will however get gains from detailed valve & seat work. depending on what valves you bought, some improvements to their shape & flow may be possible. There are real problems with fitting oversized valves in these heads

Hey Dylan , what was the total cost of the job ?

It's a bit lean down low. I'd have that enriched by about 1 point.

If you have a baseline graph can you provide that too? The gain is the important bit, the final number isn't.

i haven't picked it up yet so not sure of the total cost plus there is a few other little bits and pieces 999 are doing for me. The car has 55,000 km if your in the area i think they may be tuning it tomorrow so you could have a look.

Dave that was the last run they did when i got the PFC put in. We'll have to see what they do this time around...

Anyone want to have a guess at the gains??

thanks , might drop in tomorrow if i go up that way ..

My car has 142xxx km hence the Q about ks. I will need to get work done on it at some stage so knowing the costs help.

In terms of peak power, I got similar values to you, but with the headers must be easier to drive everyday. As SD has said a little bit lean downlow more power and torque to be had down there. You should be gaining around 10kw but don't let the numbers get to you.

lol . i will try if i happen to rock up when all this is happening but not too sure if they will just let some bloke in the workshop taking photos especially when i'm not the owner ..

Maybe whilst i'm at it i should ask for a Test Drive as well ?? :spiteful:
