I am wanting to install an external waste gate on my ej25, with a TD06-20G. the up pipes out there with the flanges already installed are great but around $500 or so. on the exhaust header there is a cross over portion to connect the left & right headers to the collector, if a external gate is installed on a aftermarket cross over pipe. Will the postion of the external gate operate just as effective controling the boost? most of the time ext gates are placed just under the turbo on subys but on other cars i have seen ext gates every where! Like on the cyl #1 0r #6 exhaust runner etc. let me know what you think, maybe we can cut a little cost, cross over pipes are alot cheaper than ext gated up pipes.
I have not seen it, do you have a web site? what do you think about the idea, dp you think it will work?
