" />i also found the source of the slight rattle and drone at some speeds. guess i have no excuse now not to have a 3" DP made. i might even "forget" to re-install the exhaust past the DP for a bit just to see how it sounds with the HE221W and a strait pipe.

" />the next step is to mount the new turbo with the w115 manifold. i would like to get the new head on however it still needs some work before its ready. i did get new valve guides and the porting but it needs valve sealing work and a little smoothing.[img]<a href=[/img]

" />[img]<a href=[/img]i think i removed around half a kilo with all the porting. the port walls are quite thick somewhere around 10-13mm.![[Image: IMG_20160729_185418_zpsfwizaqtl.jpg]](http://i346.photobucket.com/albums/p435/R-3350/IMG_20160729_185418_zpsfwizaqtl.jpg)
" />something some people might appreciate is the instrumentation i am currently running. this is the current dash with EGT, oil temp, manifold pressure, and voltage.[img]<a href=[/img]

" />i am currently in the process of replacing this one with another i made. i have a box of various aircraft indicator lights from things i have worked on before so i will be mounting those in the center for a few sub systems. (water injection active and stages, trans temp high, and maybe some others) I also have some guarded switches ill be installing for some of the aux systems. [img]<a href=[/img]

" />[img]<a href=[/img]i also managed to get a dual manifold gauge from a P-51 that reads to 100" HG.its new old stock and the serial number indicates it was manufactured in 1944. it is still calibrated i tested it not too long ago. one line will be fed boost the other exhaust drive pressure.

" />i got the w115 manifold in today. also i needed to replace my engine mounts so i got a new set an cast them full of rubber (PR seal if anyone is familiar with it. its horrible stuff its smell awful and gets everywhere but once cured its amazingly indestructible)[img]<a href=[/img]

spent most of today wrestling with the engine. i managed to get the seized nuts off the manifolds to pull the stock turbo after soaking them in ATF mixed with MEK. (this is the best penetrant oil i have ever used it even beats the Boeing stuff i used to have that was banned in most states for toxicity) also i just love the nice residue the EGR leaves behind in everything it touches.[img]<a href=[/img]" />
