8G5L0T Posted July 10, 2006 Report Share Posted July 10, 2006 Sometime in the next year i am planning on taking my 13g out and putting in a 15g turbo. The deciding factor in all of this depend on where i end up going to college. I am buying all the parts taht i need from my knowledge. I am getting everything from a friend and some of the stuff in the package im going to buy is rather random. Paul the kid i am buying the stuff from said the 16t on the engine side has a flat flange and on the exhaust side it has a conical flange. Does anyone know if this willl just bolt right on. here are some pictures. exhaust manifold showing engine sidedownpipe (wierd story)injectors on the raildownpipe connection, showing the wastegatethe exhaust half of the turbothe hodgepodge of parts: intercooler piping, intercooler rubber pieces, downpipe, fuel rail, oil hoses, water pipes, injectors, and of course the turbo Link to comment Share on other sites More sharing options...
yangotang Posted July 10, 2006 Report Share Posted July 10, 2006 16T conical? Pretty sure those don't exist in the US.And no, if it's a conical 16T it won't bolt on. You need a flat exhaust side for something to bolt right on. Link to comment Share on other sites More sharing options...
maiku Posted July 10, 2006 Report Share Posted July 10, 2006 hmmmake sure it isn't a 15G conical that you're gettinglook on the turbo for it to say 16T Link to comment Share on other sites More sharing options...
paulr Posted July 10, 2006 Report Share Posted July 10, 2006 Evan, Come on, I told you it was a 15G . A 16T on the GLT engine would be a crazy, and a 18T it'd probably blow apart right away. This is the stuff I bought off r850glt almost a year ago when I wanted to Turbo my N/A. The stuff sat in my garage for a while, then I wrecked the car, and messed up my knee, and bought an R - so I figgured it'd be good to go back on VS. It was either that, or me turn it into a jet engine. I think the engine flange is the same between the 13G and 15G, but if not, there's an exhaust manifold in there, too. I'm pretty sure either the exhaust housing or the downpipe will have to be changed for the swap, and I don't know which would be easier / better in the long run. The injectors are 310cc, which should be enough for a while. Link to comment Share on other sites More sharing options...

paulr Posted July 10, 2006 Report Share Posted July 10, 2006 can you swap the exhaust housing (I think that's the name for it) between the 13G and 15G turbos? It might be a minor performance loss, but I assume it'd be less effort than welding a new downpipe. Only reason I suggest that is I know Evan's trying to do all of this on a budget, and I'm pretty sure this project will require an ECU remap, which will add a lot...

8G5L0T Posted July 10, 2006 Author Report Share Posted July 10, 2006 i was under the impression that it as a 16t i dont know if im interested anymore. lol jk. Link to comment Share on other sites More sharing options...
paulr Posted July 10, 2006 Report Share Posted July 10, 2006 Hey if you're not that's fine, I personally think a jet engine will be freakin' awesome. But I also think that a 16T with the 9:1 compression is asking for trouble (on stock internals). The 15G should be good through 17PSI boost (or more), which is like 21PSI on a Turbo / T5 / R engine.

paulr Posted July 10, 2006 Report Share Posted July 10, 2006 20 psi on my LPT block with an 18t. No problems, and I've been running this for awhile. How the heck a LPT block takes an 18T at 20lbs when they sometimes screw HPT blocks I don't know, but it seems you obvioulsy have first-hand experience. Seems as through I'll either be Ebaying my 15G or making it into a jet, unless Evan needs the cost savings of the 15G. For those of you who don't know what I'm talking about, it's possible to use the compressor / turbine elements of a turbocharger to make a home-grown jet engine. Not that you can do anything useful with them... other than shoot huge flames, and that's always cool. Link to comment Share on other sites More sharing options...

paulr Posted July 10, 2006 Report Share Posted July 10, 2006 lots of HPT blocks can take the psiit's the A/F that screws up the engines 20PSI on a LPT is over 24PSI on a HPT (I'm getting these numbers by comparing theoretical TDC pressure). And whether it's AFR or absolute pressure or who knows what that causes failures, I just know I've heard a lot about 18Ts and 19Ts bending rods, especially at high boost, and just find one being on a LPT block impressive .
