Do I really need to change these
 

Here's the deal, I have a 93 delsol with the 16a3 and a greedy 18g kit (yea I know a kit) and its been on the car since 2001 and there are no problems at all. What I want to do is get rid of the 1 1/4 dp and put a 2 1/2 dp on, get 450's get rid of the piggy back and go with s300 and a wideband. right now we are at 225 whp and looking for 3-350 whp which is possible. My question is,should I change out the oil and water pumps just to be safe. Temp has never been an issue nor has the oil press, also there has never been any leaks the motor has only 81k

what cha think

no you are still quite good. Inspect water pump at 100k but these things rarely fail and your turbo is not stressing them any more then grandma would really.

i disagree on the water pump. i always change them with timing belts. i change timing belts at 90k. as far as the oil pump i would leave it alone. those things go forever

Re: Do I really need to change these
 

water pump if its hasnt been changed nor the t belt in a long time well time to change. A worn out belt rapping rpm's usually fail I learned that lesson the hard way with bent valves

Yeah....happend to me on the interstate doin 90.....
Fucked me all up....
I'd change the belt.....
do the pump anyways since you already takin that off
