datzenmike Posted November 29, 2009 Report Share Posted November 29, 2009 change the bell on a ka trans It could be done but you would need a shorter drive shaft and modded tranny mount. The front case would need some mods and the counter bearing on the KA tranny exchanged for a 56mm one. On the plus side you have a pre '85 tranny so any: '77-'79 620 and '80 720 2wd truck. '81-'84 2wd 720 truck. Check length for 31.5" same as yours. '77-'78 280z and '79-'83 280zx non turbo. ... should fit by swapping your CA bolt pattern front case half without any mods. NOTE: You have a turbo motor with lower 3.592 1st to get the turbo spoolin' ASAP, and most of these replacements have a higher (lower number) 1st gear. The only one is the '79 620 truck with the same 3.592 1st. gear. The zx 5spds have the lowest 1st gear at 3.062 and a monster over drive 5th, not good for a turbo. Using the 'closer ratio' trannys with a 3.321 1st. will give you less RPM drop between shifts. Just sayin'. Quote Link to comment

LenRobertson Posted November 30, 2009 Report Share Posted November 30, 2009 I was at Pull n Save Spokane yesterday. One row had two blue 620s. I'm pretty sure one was a 5-speed. No idea on what ratios. Maybe you can live with whatever ratios in order to get the SX going. There may be another 620 in a different row, but I don't know what tranny it had. Also, there's an 810 with a stick trans, but I didn't check if it is a 5-speed. It seems like the blue 620s have been there awhile, so may be in the row due to be crushed. I wouldn't wait too long to check it out. And take a tarp if you might be pulling one out. It's muddy out there right now. Len Quote Link to comment
datzenmike Posted November 30, 2009 Report Share Posted November 30, 2009 Len, all 810/Maximas were 5 spd. Quote Link to comment
fisch Posted November 30, 2009 Report Share Posted November 30, 2009 Timely question as I was just on datsun1200.com, and they have some CA trans swap info. Scroll down. http://datsun1200.com/modules/mediawiki/index.php?title=CA-Series_Engine_Swaps Quote Link to comment
datzenmike Posted November 30, 2009 Report Share Posted November 30, 2009 Scott I actually have the '85 turbo 5spd. I traded the CA 'bell' for a KAE head..... (is that wrong?) I only wanted the guts with larger gears and bearings anyway. Quote Link to comment

I only wanted the guts with larger gears and bearings anyway. Nice! The thing I like about the mention of using a 'stumpy' l-series gearbox with the CA bell, in my case, is that the shifter location is more forward. That is if one were thinking about a CA in a '59 datsun.:D CA on top and L below. Mike does this look like a dogleg 5-speed to your trained eye? They only list it as being in a r30skyline or behind an l24. Photo from Datsun1200.com Quote Link to comment
datzenmike Posted November 30, 2009 Report Share Posted November 30, 2009 Top tranny with motor (what kind is it) is an FS5W71C, the other is a short FS5W71B. Strange but it looks like it has an L bolt pattern on it. They did come on the 720 trucks and I have one but it's a Z bolt pattern. In 1980 they used the L20B so possibly from an '80 720???? What side is the speedo drive on??? Someone mentioned there was a competition 5spd made for the 510 and was short, B type shifter and with L bolt pattern but I don't think so. The 510 was gone by the time the B shifter was out. Unless it was made much later. Quote Link to comment
LenRobertson Posted November 30, 2009 Report Share Posted November 30, 2009 datzenmike - Thanks for the 810 5-speed info. Do you think the ratios would be the same as the 280 of the same year? I have a flywheel from an 810 that is lighter weight than Z or PU 6-bolt wheel. Any idea if all 810s used lighter flywheels? I'm remembering the weight being between 17 to 18 pounds. Z and PU were over 20, I think. Len Quote Link to comment
