would you say my engine is cool to turbo?
 

i've got a d15b7, and most of a turbo kit waiting to go on.

it has 115k miles,
runs good, but eats up some coolant(i have a feeling
thats the water pump though).

I just did a compression test
although the engine was only half warm(dont know
if that'll mean the results are higher or lower than they should be?)

but the results I got were this:
1. 197
2. 190
3. 190
4. 200

thanks

Turbo it, doesn't look too bad. And if it blows Hondas are crazy cheap. You could get a new D15B7 (used, but new for you) for under $200

Numbers look good, but the water pump will not "eat" fluid. If it's leaking that's a different story. Slight head gasket leak? :-\

yeah i've been trying to diagnose the coolant loss on honda-tech. Someone suggested the headgasket, and that I do a compression check, but I was thinking the numbers looked pretty good, so maybe the headgasket is good too?
which makes me think of the water pump.

Car doesnt ever leave a drop of anything underneath it.
and theres only one spot on the engine bay thats slightly moist, and I think that might just be spilled oil from when I was messin with the head.

i was thinking about re-torqueing the headbolts just in case. I heard that sometimese helps.

oh, and a bad waterpump wont eat coolant?(well not eat, but let some leak).

Re:would you say my engine is cool to turbo?
 

So, you can see the water pump leaking? It can't leak from the inside(well it can, but it won't result in a coolant loss. If you can't see water leaking out of the water pump it isn't the problem.

Those numbers look good, yes, but that doesn't mean that under WOT and a full load it isn't leaking at all. It could be a very small leak and under no load it doesn't leak. Have you looked at the oil?

you don't do a compression check to find leaking gaskets, you do a leak down test. They kind of related, but not in the info they provide. On a leak down, you put shop air into the cylinder, and then monitor the loss. Anything over 10% is borderline excessive. But you can also spot your leaks. Air out the intake, indicates that you have a leaking intake valve. Air out of the exhaust pipe, means a leaking exhaust valve. Air bubbling out of the coolant, is going to show a leaking head gasket, and air coming out of the valve cover, is going to show leaking rings.

thats a mistake

Re:would you say my engine is cool to turbo?
 

well I've only got the internet,
either that or pay a mechanic, and i'm broke so thats out :P

you guys are helpful too though :-*

Maybe i'll try a leakdown test if things get really gnarly.
i'm going to re-torque my headbolts and see if that helps.
the coolange leakage is small though, so I can sit on it for a while.
(not going turbo till i have $$ anyways)

Re:would you say my engine is cool to turbo?
 

you are never aloud to go to honda-tech again lol just kidding, numbers look good man, turbo ---- but fix ur coolant leak first

Re:would you say my engine is cool to turbo?
 

what do you think might happen if I just turbo'd it as is?
and kept a close eye on my coolant levels?
