I'm getting ready to buy a Electric Water pump.
I have very limited room ( about 2 1/2" ) .
On the CSR web site it says 2.75" Overall depth.
Do they mean the mesurement between the 2 red arrows ?

















Thanks.

Is that distance you're measuring stock? I put a CSR pump on my T/A a few years ago and have the radiator set at the stock location. If I remember right I had to trim the guard around the fan just a little bit. Nothing major at all.

I have a 1989 Mazda RX-7 , it's a bit different and not as much room as you guys.

PearlTA

Ahh, so that's why the pic looked a little bit different.

The CSR is pretty slim, but that's going to be cutting it close! A Meziere definitely won't fit, that's for sure.

I cant tell in the pic, As I am still half a sleep and have not had my coffee yet. But are you measuring the distance from the end to your stock water pump to the Radiator Shroud In that picture? If so, you might want to go measure again. A Friend of mine from TX has this EWP on his car. But its been a few years since I have looked under his hood. I am pretty sure it fit with no problems. Go measure from the block out to the shroud.





EDIT: Just seen its an Rx7. Man that might be cutting it close. What about picking up a slim fan and shroud?

I knew that , this is why I'm trying to get the CSR pump mesurement.

I just bought this brand new Taurus Fan for better cooling , I'll do all I can to keep my new fan setup.

have you called csr and asked them to measure one for you?

PearlTA

I have mine off the car right now. If you don't have what you're looking for by the time I get home from work (around 5:45 CST), I'll gladly measure and post the info.

Perfect...

I just ordered one.




One more question tho.


I'm going to Electrical water pump because mine starts to leak and also I have a oil leak where the shaft goes thru the Timing cover.
The shaft sells for $160+ usd + new pump etc.Looks like a regular problem with the LT1's , even if you change the seal it still leaks ( worn shaft )
Can I remove that shaft and plug the timing cover

Yeah you can plug it up, you'll probably want to remove the gear that drives the pump too. I just had a plug welded in the cover, but I've seen people that have done it with just jb weld and something to cover the hole also...

My timing cover has casting number # 10214196 on it so I'll try to find a used one and have it welded so when I'm ready to do the swap I won't have any down time.


Anyone has a used timing cover with this casting number on it for sale ?

Man, I bet that little 89 Rx7 Books like a bat outta hell with that LT1 in there. How much your car weigh?

....So 1 month after , I have received most of my parts to do the swap and I have started last Thursday March 4th.










I've decided to removed the radiator and fan assembly to give me more room.











Pump almost off.










Found my oil leak....Oil seal for the Water pump shaft was damage during installation . ( bought the car like that ) .





















After I removed the OptiSpark while it was in my hand , I shaked it and heard something loose in it.


Look what I've found :








One screw to hold the rotor was loose inside the case and the other one was completely backed off , enough to let the rotor move around and break the little plastic pin to center it and the rotor itself was rubbing inside the cover.









This was a faillure that was waiting to happen in a very short time.
Glad I'm doing this swap and found out that.
I put the rotor back in , used some loctite and the little broken plastic pin isn't bad , I think it is to make sure you "time" the rotor correctly , without the pin I can install it 1/2 way off.















Removed the water pump and gear.
















Stock timing cover bottom left.
Modified timing cover top left.
Stock water pump bottom right.
Modified waterpump with the electric CSR Pump top right.












It is a lot more work then I thought.
I had to removed all bolts from the oil pan to give me some room to remove the front cover.

I'm almost ready to put it back together , I'm waiting on some bolts for the timing cover and I have to order a new bolt for the hub.
I had hard time removing the hub.( wrong tools )

If you didn't do it already do yourself a favor now and put a thin layer of sealant between the ewp and the housing the o-ring doesn't always seal right

I can do that I haven't put it back in yet.
