Another Canadian B23FT build

This is my car. It?s a 87 745 turbo that I have had since 2000. It?s an Alberta car so it came to me with zero rust and about 180,000km. The rest is TB history.

I read Mcbrooms and set up a plan. I have a long history with this car and several motors (too much boost and a broken heater hose). I will not bore you with all the details but this motor began as an idea after I was replacing a HG and found a crack between cylinder #1 and 2. The cracked motor was sleeved (very long story) and could have survived a little longer with the crack in the block (not in the sleeves itself). But I decided to pulled the motor and start from scratch. New block and newish head.

I began by sourcing a block. I didn?t actually think I would find a *new* block but after looking around TB I found foggyjames. Foggy had a new, never used, b23 block just sitting around. Shipping from the UK to Canada sucked balls. I got the motor in April of 2007 and started work.

Bottom end:
Forged crank and rods from my previous B23FT.



All internals were sonic checked then balanced.
New set of stock sized Mahle pistons.



Drilled and tapped the block for turbo return.



Stealthfti?s #5 thrust bearing chamfer trick for more oil supply.
Drilled and tapped for BMW oil squirters.





more to come...

great work mods move this to projects and restos

Cylinder Head:
530 with about 40 hours of bucket work.




practice head


MVP adjustable cam gear from previous engine

VX3 cam

lapped valves
Grooved with my own variation of the Somender theory. I used a 3 axis at work and built a program to make all grooves the same (no cameras allowed at work)




Cometic HG with some Hylomar spray

Turbo:
TD05-16g
I spent about 2 hours bent over a sandblasting cabinet cleaning and polishing everything on this turbo. Sand then glass till my back hurt.


The hot side has most of the work. Hot side turned on a lathe to open up the exhaust side.


Removed stainless steel WG cap and ported the WG hole (forgot the camera that day)
WG cap was machined thinner to allow it to open up bigger
Stainless steel cap was then welded on at an angle to allow WG to open further


Hot side inlet was opened up and ground smooth with air tools

Shaft and turbines were then balanced to perfection by Herman. Homemade BOV block off plate from aluminum

Wow.

How much beer would I have to lure you with to come to Alberta and teach me a thing or two about how to do things? Hell, I'd drive out there and give you a hand on your car if you'd like. Driving to Quebec in late July

dang good work man that works takes a good eye, steady hand a lot of beer...

those groves are beautiful. what fuel system>? with that turbo expect about 250hp hopefully

What Volvo came with a 16g? Or did you machine that Volvo compressor housing for the 16g wheel?

Looking good, can't wait to hear about it being all together and driving... Was the machine at work unable to go farther down in depth on the grooves as they enter into the chamber, or is that how you wanted them done? Curious as to your thoughts on what made you arrange them in those directions, care to elaborate?

Get'r done!

87 740 is lh2.2.

Setup looks great!

I'm in London town Ontario.

klr142 - I will elaberate when I get some time. I could have built the 3-axis program any way I wanted. I wanted to do it that way. Maybe I was a little nervous about cutting grooves in my head.

did you see that little blue behind my turbo....


Turbo is completely custom.

peek-a-boo, I see you!

Great looking 1800!!!

I ordered some bits for my exhaust. With the CDN dollar strong against the US I was able to get all this stainless for $95 shipped.


a few cuts and some stretching
