The 1800 race car is getting a 16 valve b234. I have aquired almost all the parts needed, thanks to some people here on Turbobricks. I know that most of the 16v info is turbo based. But I like n/a motors and I cannot run a turbo in the 1800, for a couple of reasons: It would put the car in a class called 'SuperUnlimited' and we'd have to run against Porsche GT3s and 500hp EVO9s, also, there just isn't enough room under the hood of an 1800 for all the plumbing, nor enough room in front for an intercooler or a big enough radiator.... No Bueno. My goal is a motor putting out about 200hp that will live for 25 hours of racing. This is going to be and endurance racer. I have 4 16v heads, one freshly rebuilt w/all new valves and lifters, a b230ft block w/oil squirters, a penta block, a b234 block and a penta 86mm crank. I also have 9mm and 13mm rods, Penta 2.5 pistons (lower comp height), Stock b234 pistons and craploads of stock b234 U cams. My plan is to run the 16 valve ECU with higher flow injectors and use a larger, relocated, throtttle body and a fabricated 4/2/1 header with 3" exhaust.
The car will weigh about 2100 lbs wet, gearing will be determined by the track. My calculations show that a 3.91 gearset will work well at Thunderhill..
I need input. I am going to start assembling this pile of parts into a motor next week. Well, at least start fabricating. The penta block and crank aren't here yet. I'd like to find a set of PZ cams or possibly get an aftermarket grind, I can't get the Cat Cams website to show anything, and I understand that they make cams for the b234.
Ideas, comments?? Am I going down the wrong path? Don't hold back, let me know if I'm making a idiot of myself. I know that everyone will say Megasquirt it... I like the reliability of the Stock Motronic system. Remember, I'm not after a peaky, monster motor, I want a reliable motor that has ok power and dosen't cost huge $$$.
The build up of the car can be seen here:

It is not up to date, I'll get it updated soon with higher res images
Thanks to Justin Silva and Phillip Bradley, both are on this forum and have helped with this.
Justin did all the work tearing down the motor and Phillip sold us with the Penta Block and is a font of knowledge when it comes to LH injection...
Thanks.
