Can you elaborate on the citroen pump elec. pump conversion or even possibly do a separate thread on it? BTW Your big brake conversion thread should be archieved as well,excellent!cheers

 

That looks interesting. Did you build a scoop to direct air through it?

 

please elaborate on this electric power steering pump deal. that would be GREAT as i do need power steering.

 

Remember what the point of a BOV is: When you take your foot off the gas, the turbo slows down, and the engine stops consuming air, which means the pressure is going to try to escape somewhere. Therefore, it's going to push back against the turbo, which is exactly what you don't want. Personally, I'd mount it as close to the turbo as possible, because that's the area I would want to alleviate of pressure soonest.

 

man.... you guys and your small intercoolers.... ive got a 15row from greddy.. the front bumper had to be cut so it would fit..... i wish i could conceal that a little better..

 

here.. i photoshopped a pic so you get wat im talkin about.. and RX7 FC TII, hope you dont mind.. my camera is out of order at the moment.

 

I first did the electric PAS on my FD, I assume you get Citroens over there. The car is called a saxo, its a small hatchback that comes stock on their cars. Its basically an electric hydraulic pump that pumps the fluid to the stock rack.

It basically comes with 2 pipes and 3 wires with a built in relay.

The three wires are 12v permanant feed, earth and 12v ingnition.

The two hydraulic lines are 1 high pressure feed and one low pressure return. On an FD you will need the FD line at the pump end of the high pressure feed swapping with a citroen one but on an FC the RX7 lines fit straight to the pump and you dont need anything. I put the pump under the wing where the headlight washer bottle used to go.

I use a switch so i can turn it off if its not needed, ie drag racing or the ignition on without the engine running. you lose the speed sensitive part but the feel is really good and nice and firm with good feedback. You can pick the pumps up for about £70 on Ebay.co.uk.

 

i had a FMIC on my FD and i never liked the rad getting starved of air. With the I/C flat i get excellent air temps as per the Apexi Commander. It is ducted so the air either goes through the Rad or down through the intercooler. The fast moving air under the car draws the incoming air through the I/C.

 

we dont get citroens but the first power steering pump i see for sale, im jumping on it.

 

p.s. is this fine?

thats the one, thats the slightly newer one, the older one had a seperate resovoir connected to the pump by a pipe. It would be nice if they had the other end of the loom as it has a relay built in. Doesnt matter too much though. Its straight forward to wire in. Beware if buying from here though, they are quite heavy so shipping will be $$$.

If its an FC you have then your high pressure line will fit straight to it. You will just need to block of the smaller line. The low pressure return is the one that has the cooler loops at the front. you dont need that, just clamp a hose between the resovoir and the return pipe at a suitable point. You can just cut the metal return and clamp a rubber hose as its low pressure. As long as the high pressure is connected properly

 

what would be the bennifit of having a huge intercooler???

the stock ones is small, and even arc sellls one that fits in stock location, so what would the disadvantage of haveing a short one, esp for lets say a vmount or fmic setup???

thanks

this picture is really old:

this one is new:

 

see i dont like that...it looks like the car has retarded teeth in its mouth due to the tanks at the ends of the i/c.

 

I would doubt that you would find that pump in North America.I haven't looked too deeply into it ,but the later Toyata MR2's came with electric PAS.That was a low production sports car so I imagine difficult to source as well as expensive.

So if I understand you correctly,that pump runs continuously and doesn't have a speed sensitive or rpm cut to run just at low vehicle speeds?The toyota one has a ecu built into the pump for speed sensing,but getting it to work properly on a retrofit car might be a challenge.Although it could be as simple as using a PWM output from an aftermarket standalone.Does that pump draw a lot of power?

 

well...i already found one. lol. ebay.co.uk! they are pretty cheap too. if u need a new one, its like 200 pounds (the currency). a used one would run u abou 60-50 pounds.

 

I am sure there would be other cars that would use electric pumps, i just know that the citroen one works, I used one on my FD 4 years ago, I got similar responses from people in the uk, now loads of people are doing it, especially some of the cars used mainly for drag cos it means they can lose the stock pump, its quicker and easier than having the rack converted to manual because the FD didnt come with a manual rack and you shouldnt use a PAS rack without fluid. Here in the UK Manual FC Racks are becoming rare also and you can always switch it off.

I dont know how much draw it has but the citroen saxo is a very small car with a 1 litre engine so it cant be a lot.

It doesnt have any speed control at all and it runs all the time but i find the steering really good, i use a small steering wheel and its still easy to park but gives good feeling and responce at speed, its not too light like the early egi ones without speed control which were way too light. I use the car on the track and street.

A friend of mine has a TII and put a manual rack in it when he fitted a REW engine. He drove mine last month and thought it felt great compared to his stiff manual rack.

My Cousin has an FD with a 20b Conversion and the complete Cosmo JC subframe with steering and suspension with 19inch wheels and 365 mm brakes and the little pumps copes with it really well. Its been on my FC for over 2 years and on the 20b FD for 3 years with no problems.

 

how did you paint your IC? and what did you use? im thinking about doing that too...

 

How do you think a stock, early SRT-4 FMIC would fit in an S4? Im lookin to get a FMIC that I can fill the bottom grill on the S4 with, but not big enough that i have to cut the bumper support. Any ideas? What boost level is the ARC good to? Sorry to ge a little off topic. Thanks

be careful what u paint ur ic with reg. paint will fuxors with ur efficiancy!!

 

did u cut that bar out behind the ic core?? i have a core very similar and was wondering how to mount it lol didnt think it would fit there with the bumper still.....

 

did you paint your intercooler??

 

Here are pics of my self made v-mount
As you can see, I´m still going powersteered.
The tubes are 66mm and 70mm.



Its the intercooler that comes stock with the new BMW 535d,
thats a 3.0 l twinturbo diesel with about 270 hp



To make the vmount possible I changed to a electric fan ( also from BMW )




Just last weekend I´ve added the plastic cover over the radiator, it ends on the top of the oil cooler. Yes, I´ve moved the oil cooler, its now below the intercooler.

To improve air flow to the intercooler I´ve added a plate that goes from the
top edge of the front inlet to the top edge of the intercooler, seen at the top of picture4 and at the bottom of picture 1.



This is the view from the front air inlet, on top you can see the intercooler, below that the oil cooler, and behind them reaching the lower end the radiator with its fan.

I´m thinking of adding plates to the side, so the air flow tunnel is complete and air
entering the inlet has to move through any cooler.
And there are still some other things to finish/replace.

All i had to do was remove the bumper reinforcement and bend down a couple metal tabs to get it to fit correcty.

Yes i painted it, its just a very light coat over the fins so it does not affect cooling.
