Sorry to bug you guys i did search but didn't find anything. Here is the deal:

I have a friend in another country who i am advising on an NA build (im a turbo guy myself), machine work in this country is non existent so I'm having a block built for him here in the US that will be shipped to him, my main question is how much will the stock (non-ported) head limit him? Is it safe, like will the stock valves be ok?

Here is the proposed setup:
-fully built/sleeved b16b shortblock 85.5x89 with 13.5:1 pistons
-skunk2 pro mani (open to other options)
-vibrant 4-2-1 header possibly 3" collector mod (open to other options)
-skunk2 pro2 cams/valvesprings/retainers in a 100% stock unported b16b head.

all this is going in a CRX that weighs 1800lbs and hoping to crack off 12.0's with street tires (class rules).

advice/opinions welcome and appreciated!

 

damn, anybody?

 

headwork will limit the power output but it will still make good power. the header choice will also hold you back alittle.
If it was me i would use:
victor x manifold
a better header
pro 3 cams
get the head work? imo

the header has to connect to an exhuast system or else we'd use an ANR side exit damn rules! you NA guys are using the victor X!!?? I've seen tests were the skunk2pro beat the victor X by 15whp on a ~300whp turbo b series, would the results be different on an NA motor?

Pro 3's arent the pro2's good for 260whp? this motor has to be pretty damn reliable...

 

d/d?
ssr street sweeper connects to the exhaust and has great ground clearence
"i" would use the victor x for your engine. i am not saying it is better that the skunk, but i would thing for the size of engine your putting together it will help out when you do the head work.
what gas will it be running?

dedicated drag car, i believe 110octane, the six sigma header is sweet but for that price i'd go for a custom hytech unit... ty for the info so far...

 

their are enough fakes out their.
i havent seen a case where pro3 lost power over pro 2
hytech big tube "replcate"header should be good for you. if you are running race gas why not up the compression into the 14 point range? 13:5 can be run on pump gas

if by pump gas you mean 91-93 octane then ehhhh not really, you can but your gonna pull so much timing it's gonna cancel out the gain imo... dont forget this motor has to last as machine work is non existent in the country this engine is going to, i cant have any premature engine failure or run parts that wear other parts really fast just to gain a few more HP, id rather this motor be down 10-20whp but last a long time ya know?

untill you take it to the track and put the race gas and race tune in it.
.
good luck with the build

 

also who will tune the engine in his country?
