What size wastegate and what manifold style is best?
Hi,
quick intro:
building a EG turbo track car for a bit of fun but am new to hondas so you may have to bear with me:
basic spec:
b18c4 darton sleeved to 84mm
CP 9.0:1 pistons
manley turbo tuff rods
lightened std crank
king bearings
ARP mains bolts
baffled sump
type r oil pump?? is this necessary? i hear you can get TODA gears? is there much difference to OEM? dont see many oil flow related problems
ARP head bolts
supertech nitride valves
supertech bronze valve guids
supertech titanium double springs/retainers
mild headwork
cams and gears undecided
hondata s300 ecu
custom GT30 BB turbo, .72 intake housing, .82 exhaust
i imagine ive forgotten some bits but that will do for now
What i want to know is what size wastegate will i need to run to ensure no creep? i am aiming for a reliable 500hp without over compromising anything. I have seen there are different styles of manifolds as well, the most common i see are the ram manifolds. what is the reasoning behind this? best for cost? best for flow etc?
this build is going to be done on a 'budget' so if i dont need to for out $1k for a full race manifold i dont want to have to!
Any input is welcomed!
Cheers
Chris

Re: What size wastegate and what manifold style is best?
as soon as i saw full race my wallet started crying 
haha
i have to admit i have just seen that top mount cast manifold a few threads away from this one so may speak so someone about that kind of style but need to think of intake capabilities and hood clearance . . . i dont want to run a filterless intake as i did that on my GTR and after about 2 weeks my intake wheels looked like they had been pepperpotted :S
