if you have a large external gate turbo it may help performance, it will also be very loud and a large defect.
if you have an internal gate turbo it would sound like crap and still get you a large defect.
give the machinist the pistons with the block to be machined. you don't want to just guess the clearances.
rips also do other modifications to their standard NA parts builds. they aren't just slapped together to hold 600hp
it helps bring on boost faster as the wastegate has no way of opening before hitting boost. its also useful in high exhaust back pressure applications (such as antilag) where the pressure can cause the wastegate to leak/creep open
the other way to set up the boost control is to run the solenoid the other way so that it is NC instead of NO so no duty = max boost and high duty = minimal boost. that way the solenoid is closed and off when the turbo is building boost and then starts opening once it is on boost. though this is entirely reliant on your boost controller/ecu being mapped by duty cycle rather than set a boost level and leave it also if the solenoid/controller fails you run unlimited boost.
My fluid level switch will be hooked up to an input on the ecu, when it triggers it will change to secondary fuel/ignition maps that have been tuned without WMI that way if the tank starts to run low the ecu changes maps early (there will also be a switch on the dash to manually switch to the non WMI maps)
Some people have been lucky enough to make more than 300kw on the stock bottom end and others have not been as fortunate. there is no guarantee that the stock bottom end will hold as is.
the issue there is he has said he wants a RELIABLE build for 300kw and you just cant assure that with a stock 200,000k motor that you haven't even opened.
bubba, i will be able to tell you what mine gets in a couple of weeks (GT35R 0.82 rear, 25/30 with 9.4:1 comp, ETM manifold, external gate) should be fairly comparable with your setup.
as much as i like a good honda bash.
The green dragon is the slowest, followed by the red dragon and then the yellow is the fastest unless its one of the other coloured dragons with a racing stripe and nos.
so in conclusion i vote that they will both do a 14.7 @ 98 unless they invest in a dragon.
it will have a chunky power band from 1500 - 5500 more than that and there is so much exhaust gas that the turbo cant get rid of it and backpressure starts killing off all the power.
there isnt that much difference between a GCG rebuild and a new turbo. you will find the power peaks and is all over by 5500-6000 on the RB25 highflow.
