well twilight had his head ported and intake manifold polished and he says with tuning from a new ECU he is expecting 15-20whp, it is alot of restriction being freed up from that.
I think a good port and polish job should run between 500-800bux depending on if you have manifold and valve work done also.
and to what degree you port and polish has something to do with it also.
The theory is with the head ported, the mani polished, some valve work, custom ground cams and tuning you could theoretically reach a good 30-35whp gain. yes all that will cost you a grand at least but we are talking a 30whp jump N/A, imagine that plus boost, wow.
now I have to wait for Darin to chime in with his glass half empty/it wont work untill I see it work attitude.
bl0rt
I would pm twilight as he has had a bunch of this work already done.
As for forged internals, the crank is already forged, the pistons have been upgraded with a better crown and such in the newer engines so the rods would be the most important/beneficial forged upgrade to make.
I think a set of 4 pauter rods is like 720 plus shipping retail.
It depends also what you are looking to do, I like a partial N/A buildup with a SMALL boost application to put me between 200-220whp. Of course at that point I assume I will be greedy enough to want to make 300 at the crank.
also these are plans for over the next 1.5-2 yrs.
Most people would be happy with a spool stage2/3 or hiboost and crank it up if you have forged internals and good tuning.
GL with your engine either way you go man, sux to have random s*** like that happen.
I know it didnt happen during gas but how much of a shot were u using? 35, 50?
