How long does a Nissan GA16DE engine last?
GA16DE does not have any hydraulic lifters, so you should regulate the valves every 30,000 miles of mileage (40,000-50,000 km). Valve clearance (cold engine): inlet valves 0.25-0.33 mm, exhaust 0.32-0.4 mm. GA16 engines have two timing chains. Their service life is about 150,000 miles of mileage (200,000-250,000 km).
What’s the difference between GA15 and GA16DE engines?
Its main difference from GA15 is cylinder diameter enlarged to 76 mm. New pistons are used, compression ratio is 9.5. The first versions were equipped with carburetor and 12-valves head (8 -valve cylinder head happens rarely) with one camshaft. Those were GA16S engines. Such modifications might have catalytic converter or not have it at all.
What happens if you ignore your timing belt?
Ignoring your timing belt can come with a high cost. Timing belts don’t often snap, but when they do, it can cause piston damage, ruined cylinder heads, and engine valve damage. Probably, when you think of your engine, you picture the valves and pistons, but you don’t think much about what keeps them in good working order.
What’s the compression ratio on a Nissan GA16DE?
New pistons are used, compression ratio is 9.5. The first versions were equipped with carburetor and 12-valves head (8 -valve cylinder head happens rarely) with one camshaft. Those were GA16S engines.
How to install exhaust cams on Nissan GA16DE?
Install the exhaust cam sprocket and bolt fin- ger tight with the chain mark aligned. Reinstall all of the bearing caps (reapply silicone sealant to the distributor mount cap). Evenly tighten 1/2 turn at a time on each bolt until all of the caps are snug (1.4 ft-lb and again to 4.3 ft-lb). The cams can break if this is not followed.
What should the ignition timing be for a blown alcohol engine?
Less ignition timing is needed for higher power ignition systems. For a blown alcohol engine with an old 2 primary ampere magneto, 38 degrees of timing was common. With a higher power magneto near 4 primary amperes, 36 degrees of timing is common.
How does engine speed affect the timing advance?
The engine speed operating range affects where the timing is the best. Increasing the timing advance raises the high-end power, reducing the low-end. Decreasing the timing advance raises low-end power, reducing the high-end.
What’s the ignition timing for a Drag Race Engine?
Ignition timing is a tuning tool for professional Top Fuel drag race engine builders. The spark advance in a 10,000+ hp nitro-burning engine is typically as follows: Idle/staging is typically 55 degrees to ignite the cylinders with a rich idle mixture. Launch typically 50-53 degrees adjusted for an optimum power at launch.
