Frankline Engineering in New Zealand makes a nice kit for and EWP. They offer a water neck delete option with A/N fitting or hose barb attachments or a full filler neck delete and alternator relocation kit. Both for a very reasonable price.
If you have access to talented custom fab work, removing the large factory water pump housing opens the engine bay up quite a bit. Allows for more creative possibilities. Turbo placement for example has way more possibilities. Here is what I did with the extra space. The turbo placement gave me room for pre-turbo WB, backpressure and EGT sensors.

AGREED about the tidiness.... running DC EWP and Controller since it wasn't even sold in the US (2004).
Now with 'new and improved' flow and metal-bodied construction of the EWP130, PWM controlled by the ECU (via solidstate relay).
What drove the choice of the DC EWP originally was it's use in the 24 Hrs of Lemans winning Aston Martins. While I realize that a 24 hrs race durability may not indicate ultimate durability, I think it's a decent good proxy. TONS of plastic OEM coolant components since. Along those lines, the plastic bodied construction is often mentioned as a design shortcoming, but over the last two decades, I haven't noticed or heard of any actual failures. But all of that is mute given the recent DC design and performance improvements.
Unfortunately I can't comment about the Meziere other than to say they have an excellent reputation.

what a nice engine setup although im installing this engine into e30 bmw. I will have to reroute some of the pipe and stuff
also i want to ask.. since i removed the stock air pump and install the pulley kit from pettit. Because im using single turbo anyway.
Can i use stock bmw reservoir that is build in on the side of the radiator ?
thanks

I was getting ready to buy the kit from sakebomb along with dual oil cooler kit.
do we really need dual oil cooler ?
Sorry for out of topic.

I have been using Davies Craig EWP since 2000, pretty much when it was released from memory, as they were developed in my home city, Melbourne. The initial version pump did have some internal sealing issues that meant coolant passed through to the motor bearing and it would seize or leak. That was resolved by 2002 and they gave me a new one free of charge.
I have since heard many stories of the ABS body design cracking and leaking catastrophically. However, this was always in motorsport applications where the pump was solid mounted to the body and using motorsport braided lines. I would recommend always isolating the ABS style EWP using rubber mounting and rubber hoses. The aluminium versions probably don't suffer from this to the same degree, but I still avoid solid mounting the pump - or indeed any external pump. It just makes sense to isolate with rubber mounts in the same way as intercoolers, fuel pumps etc.
However, in general, EWPs have been used extensively in top level rotary drag racing and circuit racing in Australia for 20 years with great success. I have never heard of anyone in the rotary world using the Meziere pumps, so I cannot comment on them.

I don't see why reusing the BMW reservoir would be an issue.
I also forgot that I pretty much have a full electric water pump adapter kit for a 13B REW sitting in my garage among other things. This includes a Turblown water pump housing block off plate and thermostat/bypass replacement plug. Also have a slightly used Davis Craig EWP 150 pump, EWP friendly modified factory water pump housing and aluminum AST with previsions for the Davis Craig coolant sensor. If your interested, DM me your contact info and I can send you pictures.

Sorry for out of topic.
Rotary combustion characteristics and engine design places an extraordinary demand on cooling... especially on oil system cooling. ~1/3 of cooling is via the oil system. Combine that with the other rotary specifics demand on oil, and dual oil cooler become important.

Thanks i will probably go into it if i decided not to buy from sake..
Thanks sir

I have the original omp.. i think its the small one.. i believe there are two omp .. one is keihin one is i forgot. But one of them smaller.
mine is small one.
on your point of view.. should i keep the omp and make it work with haltech. Or i simply go delete it and mix on the fuel. So i can use syntectic oil into the engine as well.
because there is no way to test my oil injection working properly or not right?
would it be better for me to delete omp?
please advice

To expand on this, a dual oil cooler is not really necessary, but good oil cooling is. The FD used a dual oil cooler for packaging reasons; the front of the FD does not have a lot of space to pack a radiator, oil cooler(s), and intercooler, so oil cooling was split across two smaller coolers, which were mounted to the sides of the radiator. The FC RX-7 used a larger single cooler. Your best solution depends on the packaging in the front of the E30 chassis (which I'm not familiar with). It might be easier to use a large single cooler rather than smaller dual coolers; the important thing is to have enough cooling.

Yep! Dual oil cooler first, and if you need more cooling we do have our EWP kit... but for most cars unless they're dedicated track cars we usually recommend starting with our Dual Oil Cooler setup first and checking temps.

yes.. i saw otger shop sell a oil cooler which flow on both cooler and share the oil cooling job together
is this method better?

Dual coolers may not be required but I would absolutely NOT reduce both the capacity and the quality of what you're going to use. CX Racing is basically a junk ebay brand. If you're going to do it then you might as well use a high quality core.
Also, I'm not sure that a single cooler is necessarily easier to install. It's one more bracket and an extra hose to install dual coolers, but the major effort is otherwise the same.

Hey yes thanks..
I think i found 1 place with everything i need from fuel , water , and oil cooling
I will posted what i buy
Since sakebomb did not respond me for weeks
too bad
