Thread: ga15ds

we about to have fun with our ga15ds......but needs help..... here my setup
weber 32/36 downdraft, 272 cams (idles rought) custom CAI. the car revs up to 8g rpm but it revs slow all the way to 8g.......

Hi man!!!

In my opinion, change the webber for twin 40/40 mikuni (webbers) and put velocity stacks. Chec your BTDC cams timing. What exhaust you have?

Yea, sounds like a cam / ignition timing issue ..what distributor setup are you running ?? What is total advance ?? Should be in the 32 deg. area ... ignore base timing , just set it to about 28 total at about 4000 RPM with no vacuum advance, ... Make sure the vacuum advance is working that should bring it up to about 32 when connected ...

23/36 should work good ... I ran them on a bunch of cars ... my old L20 Datsun would turn 7K all day and ran really well with a 32/36 ....

ok i have a weber 40 /40 sidedraft but no manifold for the b13.... i have the stock exhaust still... i need to upgrade, what size pipe u think i should used?

sweet info man.....

Pacesetter 4-2-1 header with 2.25" exhaust. I tested and retested this setup .

im running the stock dizzy with internal coil for the time... i dont know my total advance yet..... i would let you know soon. thanks man

And that dizzy is from an engine that had a Carburetor stock ?? The GA15DS would have had a Carburetor ... But if your GA had Fuel injection and it was really a GA16DE then that dizzy will not work for a carbureted setup !!

I Just Have To Check The Total Advance Timing But I Not Getting Much Power At Low Rmp
