My 242 I bought back in 2008 and my first Volvo I bought. I paid only $350 for the car. The car was left with a half a tank of gas for five years. After switching fuel tanks and pumps and some basic maintenance it was my daily driver through high school.
My goal was to do a resteration project with my dad that has great talent with bodywork. When it came to building a motor my first thing I wanted was a turbo motor. I begain to wanting to do something different but still volvo. I decided to do a N/A build.

Been doing resarch of what redblock based motor I'm going to use. I thought of doing a junkyard 10.3:1 b23f but I wanted to build a motor to my liking instead of pulling one from the junkyard. I found out about volvo penta redblock with 86mm cranks and decent flowing heads. Looked on CL and found a AQ151C and paid $500 for the whole engine.
When building the motor I've decided to use b230ft pistions instead of aftermarket and the same for the rods. The b230ft pistons required some machining because of the longer stroke on the crank.

Here is the specs of the motor

B230f squirter block
86mm penta crank
13mm rods
First OS pistons

531 marine head
38/46 SS valves
AGAP camshaft
11:1 CR

Nice. Love n/a. What hp are you aiming at?

Should make 170+ at the wheels. I'm sure I need a different intake instead of the stock b230.

What would anyone recommend on injector size I should run. I may run 50 shot of nitros with this motor for fun.
I'll be running LH2.4 to start with.
 
Pretty sure you will be fine with orange tops, maybe some from a P2 2.5T for better atomization.
 
you doing your own getrag driveshaft...if so I want you to make me one as well for me
 
Great build, nice to see a different avenue being taken. My uncle has been telling me to just NOS, ever since I started asking for help on my +T, very nice.
