Type IV Engine
Her's  my 2550 cc Type IV engine. Modified MSHP 6 stud heads, 44x38 Manley valves, 102 mm x 78 mm,  Eagle rods, FAT cammed, Torque Generator.
Haltech fuel injected using 914 2L. heads and modified runners, modified T2 plennun,
and a throttle body off of a GM 3L V6.

making every thing fit 
Getting all the parts to fit, making sure I have everything. Many of the parts show here have been either modified or changed as I found out what would work.
can you say BIG? 
102 mm Nickasil coated aluminum barrels and pistons from LN Engineering. Absolutely the best money can buy.
ooh, ooh 
The view a piston will get. 44 mm x 38 mm poppets
bits and pieces 
Getting ready to assemble the "heart"
oh boy 
Well, here it is. Starting the fit check of all parts just to make sure that no two parts try to occupy the same space at the same time.
more work to do 
Doing the fitting of a GM throttle body. I determined from this exercise that the Bus plennun won't work with 914 2L. runners and of course the 914 plennun won't let the engine cover close. So a Modified T2 was built.

The engine is complete and in the car running. It has a very sweet sound to it. Sort of a low authoritative sound that is well muted by the muffler. The intake noise is also a different than what I am accustomed to hearing coming from hot rod VWs, it is somewhat muted and has this urgency sort of sound. Very sporty car sounding. Click Here to view it. There is still some details to take care of. I have to finish the air cleaner and get it hooked up to the body air duct to ensure cool air. There will some minor wiring changes to clean it up a bit more. Already gone are the dip stick for the automatic transmission and the kick-down switch for it.
Zoomy!! 
Here's the view under the car of the right side of the exhaust. 1 5/8" tubing, 1 1/2" stub tubes, 37" primary length, Ceramic coating by Proformance Coatings here in the Seattle area. Not visible here is the stainless steel heat shield between the tubes and the bell housing. The outlet comes out in the stock location under the apron. No visible clues as to what lurks with in!!! Note: mock up engine in these pix.
 
Here's the view from the right wheel well. The collector has a bung for the O2 sensor plus the muffler section has a bung to run an outboard O2 sensor for tuning purposes. Gorgeous work done by Stan's Muffler Shop in Auburn, Wa.  They are noted for their custom hot rod exhaust systems. No, they ain't cheap!
the pipes This is a shot of the exhaust  just before installing it. When I changed transmissions to the 4 speed, I had to have a new #1 pipe made. The differential houseing offset caused this.

The tail pipe 
all alloy
Here's a shot of an all alloy T4 engine. Head studs are LN Engineering and extremly nice. I have been running .005 on my valve adjustment and so far it seems about right. I'll be doing some hot checks of lash.
