Anyone using a 20XE on throtttle bodies got a manifold without the water elbow on it ?? reason im asking is ive looked at several and some have the elbow and some dont, what happens if you run without the elbow ?? Obviously the water feed is blanked off but does this create any cooling issues as then the only way in /out is through the thermostat and out the pipe at the other end of the head, and advice gladly received
All the intermediate inlets for the xe/let should have the elbow, some are built into the casting other have a bolt on application.
You can't go without it unless you totally revise the cooling system.
DTH bodies dont have it, but they still have the smaller water stub by the alternator mount, all you have to do is swap the rubber hose for a normal 2.0 8v item as it dosent have the bit that joins to the manifold.
the engine does not over heat or have any other problems, my engine was like this for about 3 years and it was fine.
Reason i ask is because im building a bespoke manifold for my new turbo lump and was looking at using a throttle body manifold as the base, my existing LET engine warms up very qiuckly and only has to sit for a few mins in traffic and the fan is on, i wondered whether running without this elbow would create me lots of new cooling problems
Forgot to ask, if you use the small 8v type pipe, where does the other end go to ? Obviously it cant go to the back of the water pump like the normal elbow does ?
yea, it comes from the black plastic hose to the stub on the back of the water pump elbow, it dosent have a take off for the large manifold return, you dont have to get the hose, just block the smaller stub of with an old socket, thats all i did.
