Vauxhall Corsa C and Combo C have the ECM bolted to the column assy. They are plug and play..

Cheers 👍

Electric power steering is normally done on the column, not the rack.... So then you just need an unassisted rack of your choice bolted to the axle.

It is doable to get the column down to a rack on the axle, have seen it on a US racer, but it involved quite a convoluted path...

Hi from what i can tell that how it was being done earlier on, i think most modern stuff has the motor built onto the rack using a ball screw arrangement. Do you know if the column arrangements used an ecm or where they just simple power in jobbies?

How are you planning on getting the mechanical connection to the rack? Electric racks I've seen are only assisted.

Hi i intend to use a custom made spline arrangement, you can get any diameter up to 4m long made up using delrin a hard acetal plastic as a internal wear resistant sleeve with universal joints either end where it goes into a miter box then up to the steering wheel.

Has anyone on here had anything to do with electric power steering racks? 
my build has 16” coilovers and 4 link arms on the front allowing up and down movement only, unlike a panhard rod that moves in an arcing motion. To  eliminate bump steer i intend to use an electric steering rack of something heavy to bolt to the top front of the axle. What i need to know is do they require a module to work or can it be bypassed or something, maybe a potentiometer or resistors? Ideally the rack will come off something with the rack in front of the wheels not behind as i don’t fancy reverse steering😂. The truck is road legal so hydraulic is out of the question, and a conventional box would result in horrific amounts of bump steer. Please only comment if you have some knowledge of electric steering racks. Any info on this would be greatly appreciated.

Thats awsome red 90 thanks for taking the time to write all that out. I really appreciate it. 🤙 

[2.25 petrol cam specs for stainless exhaust build]

These are some of the bits i did for my 3.9. I loved making them and am ready  to do it all again. 🤙

[2.25 petrol cam specs for stainless exhaust build]

Just looked up the green bible its £50. I met a guy at a landy jumble that had a nice set of custom headers on a s2. He reckoned it freed it no end. You only have to look at the pig iron manifold and poor pipe design to be able to tell gasses aren’t going to want to go down it. 

Any info would be much appreciated. 

[2.25 petrol cam specs for stainless exhaust build]

I am contemplating making a full stainless system for my s3 lightweight. Can someone advise me further on these specs for the calculator. The ones i have used are from hours of googling so probably all wrong!

Many thanks joe

[4.0L THOR. What is required to make it run!!!]

What about the non thor 4.0L engine the one with the traditional trumpet housing. Was this one as complicated or did it use the same tack as the earlier 3.9s?

 

[4.0L THOR. What is required to make it run!!!]

Hi all 

I am looking into buying a 4.0l thor out of a disk 2. My question is what is required to make it run. Obviously it is going to need the engine loom& ECU, AFM,LAMBDA SENSORS ECT. Is there anything else like alarm, ignition coding? Does anyone have a wire diagram they could post. Cheers

Why do you care?

Sequential has almost no benefit apart from emissions at idle, and firing at the back of a closed valve is actually beneficial, it cools the valve / charge, vaporises the fuel and allows it to swirl.

I care because i like to know how things work and what i am dealing with. Hence joining this forum and asking questions. Although I appreciate the info. 

[Sd1 rover v8 3.5 efi flapper injector timing?]

So does anyone know if the 4.0 thor engine is sequential of not?

[Sd1 rover v8 3.5 efi flapper injector timing?]

Fair play i guess it makes sence to of preloaded the fuel instead of trying to jet it all through in such a small time frame. It kinda makes me think spray pattern shouldn’t be so crucial if it hasn’t got spray       Perfectly around the valve just dump the right amount in and then suck it through right? But then i guess a neat spray is the correct amount and anything other than neat is less fuel? 

 

Cheers for the info guys its much appreciated!

[Sd1 rover v8 3.5 efi flapper injector timing?]

Hi bowie69 so you are saying it just squirtes fuel at any of the 8 ports regardless of wether the inlet valve is open or closed. Then when the inlet valve opens the incoming air will drag the puddle of fuel through haha 😂. That has to be the crapest system i have ever heard no wonder they don’t just fire up on the first kick.  

Thanks for the reply🙂

[Sd1 rover v8 3.5 efi flapper injector timing?]

Hi all 

i am new to this forum business so please bare with me. I have a 3.5 efi and can’t for the life of me work out how the ecu knows wich injector to open. I know it picks up a pulse off the coil that comes from a halleffect sensor on the dizzy. But all the ecu recives is 8 identical pulses? How does it know to squirt on say cylinder 7 and not on say cylinder 2
