Hi all.
Over the next few months I will be building an ALH to swap into my 2003 Toyota Tacoma. I'm currently in the process of cleaning up the motor I just bought to prepare it for performance upgrades. Among those upgrades will be a larger turbocharger and custom FMIC to give the engine enough power to move the truck.
One of the things I am frequently seeing on tuning sites is the list of necessary performance parts needed to support a given tune. In the case of say, a Malone stage 4, they list a VNT17 as being needed over the stock VNT15. What I am wondering is: do I need to run that exact turbo or will I run into any issues building my own turbo manifold and sourcing out a different, but similar, turbocharger? Does this same idea apply to the intake manifold (I hate the design of the stock one as it favors the two middle cylinders)? My ideas here are:
a) I love building stuff myself and have a shop fully capable of doing so
b) I'd like to build a manifold with a turbo flange that is more common, thus allowing me to run any turbo with that flange style, and
c) The stock turbo setup on the ALH interferes with the starter on the Toyota R150F transmission I will be running.
I have attached an image from another Toyota build/swap similar to something I'd like to do. I am just not sure whether or not I'd be able to run a tune with a different turbo than is listed. Any insight on this would be much appreciated. Thanks all!!
