Looks like a fun project. I think it will be large for a 1.6 but with vanes closed it will likely spool faster than a K24 or T3 and be able to flow rod-bending boost efficiently with vanes open. As far as spooling as well as your last turbo, I can't really say. I can't really account for how your last turbo performed. I've used a couple VNT15s on 1.6TDs and with vanes fully open and close-to-stock fueling and they have a hard time making 7-8 psi of boost.
you said it yourself tho, that i am DANGEROUSLY over fueled.. and im going to buy an EGT gauge today, to see exactly how right you are..
my pump always made 20psi (with ease) or more with a VNT15, vanes fully open.
i hope it doesnt matter that this is a StreetToys 2000 hybrid turbo. i hope that doesnt make it a laggy dog.
rod bending boost you say? so, basically is what your saying, is that head studs are basically a requirement for this turbo?
should i do anything to the bottom end of the engine? its 100% stock right now..
I should have said that the only way I can account for your ability to produce high boost from a VNT15 with vanes fully open would be from excessive fuel. I think the Street toys turbo with vanes fully closed will spool as fast or faster than a VNT15 with vanes fully open. I think the head gasket will be a weaker link than the bottom end.
ok, well... i have one more question about this setup..
AM I ASKING FOR PROBLEMS??
is this turbo going to harm my engine?
(im actually going to be monitoring this engine, i got a 1600*f autometer pyrometer today)
i need to get head studs tho..
and lucas, i would think that my precups would actually like this turbo MORE. its going to be more efficient, and flow MORE air, so it should run cooler EGTs than my VNT15, or K24 ever ran..
BTW, dunno if the markings are accurate, but they say the cold side is a .45, and that the hot side is a .64, but being a hybrid turbo, and knowing ABSOLUTELY NOTHING about the actual specs, its kinda a guessing game, right?
i am planning for a set of head studs, and a metal head gasket if the fiber proves to be too problematic, im gonna try and run a fiber gasket w/ studs at first, and see how it likes it. VNT turbos should be/are actually easier on the head gasket, than conventional turbos. the VNTs have much lower drive pressures than the conventional turbos. the exhaust side of VNT turbos flows AMAZING at high RPMs..
please, someone tell me if im just stupid for wanting to run this turbo, or if it will be completely acceptable with the right fueling and mods? i dont want to set myself up for failure. i dont want to have a sob story to post, for you guys to laugh at..
