My Rex rebuild
« on: December 28, 2013, 02:43:26 PM »
Well happy seasons everybody, I\'m back at home for a couple of days before the brown stuff hits the fan at work and I go back to live in my mobile tin can,
Just spending my 48 hours off chasing up parts and looking at spending more,

It\'s at this point I\'m after all the advice I can get,
Well the best Christmas present I had was checking my bank balance and still seeing 4 figures and no - symbol so it\'s shopping time,

My engine builder has called and told me my engine is done and sat there waiting so we are all go,
I have a shopping list as long as my arm still but for now I am focusing on getting the build running and then I can go handling and cosmetic,

Right advice time,
I have been speaking to Ed about turbos but I want to check with everyone else I am making the right choice,
As you know my engine is running a street port, I have purchased one of his divided manifolds and a waste gate that should be arriving anytime soon,

My main criteria to him was a quick spooling turbo that can get me well into the 400+ club as I am used to 350hp cars and they just don\'t cut it no more,
I don\'t want serious lag and at the moment he is recommending a t4 turbonetics item with billet wheel etc but I need a second opinion and maybe some other options smaller larger who knows,

I am also looking for reliability over anything,

The second thing I am after more info on is electronics should I invest in water injection, ignition boosters etc, I am going to be running a haltech ecu all going well,

I don\'t want numerous gauges so am looking at haltech stack dash consoles,
Give me some reviews and maybe a list of things I should be looking at, fuel pumps regulators etc,

If this was a v8 or a pinto I would know what in doing but obviously this is all very different,
Also anything you have for sale may be of interest to me now, what say you fine people

I have been doing a lot of research on ECU technology recently and up until last night I was set on the haltech platinum system with wideband module, stack dash logger and fully terminated loom, pretty much plug and play bar mapping,
That\'s where my problems arose,
I found plenty of people who claimed they could map it but they either had no rotary experience or previous customers had complained that it was a :censored::censored::censored::censored: map ,
When quizzing a few of them it turns out they just don\'t have the equipment to do a full road map, they just tend to bollock a load of fuel in and do full throttle "race maps"

Obviously with the rotary being a tempremental beast I don\'t want to take the risk,

Anyway I got talking through a friend to Dave at emerald and although his ecu is not as intelligent or have all the plug and play facilities it does tick all the boxes, triple maps which are switchable live monitoring and he has years and years of experience and most importantly has not tried a hard sell or bull:censored::censored::censored::censored:ted me,

Has anyone else had any experience with the ecu or have any more insight into this decision,
Obviously the haltech is the one to have but this route I will have a one stop shop, he can supply, fit and map in house and he is a guy I can trust.

All ECUs are essentially the same, but you need to take it too a rotary specialist. Boost and fuel are easy enough to play with but when messing with timing I believe that when people who don\'t know rotaries end up blowing them up.

Powergains would be a place to contact about mapping a Haltech.

I think tinker, v8 twin turbo FD, has an emerald ecu and he\'s running 1000+ hp. They seem to be prety good

Well the emerald works out a lot cheaper and I trust Dave, but a rotary specialist does swing a lot

Dave from Emerald is a mapping genius so will be more than fine in his hands. He wrote a book for Haynes on engine management.... if you understand internal combustion you can map anything.

Dave walker, he don\'t like rotories as far I know for past 25 odd years. I would not ask him anything about tuning the rotaries
He may be a genius to :censored::censored::censored::censored:ton world and to me and he\'s bit clueless

Dave\'s a brawbag anyway.

i am not sure jaydee at the moment i have just been looking for units compatible with a rotary or units that are rotary specific, every time i always end up coming back to haltech though

fully terminated looms, ease of use, all the extras that are available, ok the price is a little heartburn inducing but i want my car to be the best it can be and reliable


CAR PARTS!
yay more car parts thanks to ED
must admit this one kind of scared me, rather large, in fact bigger then my old turbo lol


think ED has become a unofficial sponsor on this build, already providing manifold waste gate and turbo and maybe soon the ECU

cannot recommend him enough people

right people, need a few parts and i need to find them in the UK or wherever at a price that won\'t make the vatican jealous.

first off i need blanking plates,
OMP,air pump imp lines etc etc , a full kit would be nice, i just don\'t want to pay £20+ each for something i could hacksaw out of a bit of scrap.

i need inlet manifold gasket and TB gasket etc,

i need exhaust and manifold gaskets and i could do with solid ones that won\'t blow apart at the first sign of boost.

planning on fabricating a down pipe without a kink and with a lambda boss, anyone made one up before or have one for sale?


braided brake and clutch kit,
etc etc

before the engine goes back in the bay i have tried to figure out why i was getting so much play through the steering wheel, i was able to turn the wheel 5\' before encountering any resistance or movement through the steering system,

my rack steering rack is grind or juddery but still got a quote of £95 for a rebuild which i may or may not do,

when i removed the column it all seemed nice and tight apart from the bit at the top just before it goes into the first UJ there is a tiny bit of movement and i mean a fraction, nowhere near enough to encounter that kind of play but i may be wrong,

anyway when looking up steering column replacements and rebushings etc i noticed my column doesn\'t look like any of the pictures, theres all seem to have a rubber doughnut bush, mine is just a sleeve (this has the movement) a UJ and a pin which also allows for the movement,

does anyone have a solid replacement or any suggestions on what i could do, i don\'t want to buy brand new and get manual racks etc but i would like tight crisp steering that won\'t kill me

Bit confused? You have a manual rack already? If your uj are backlash free than must be internal in the rack.

I don\'t know that\'s the problem none of it looks like the pictures, the steering rack itself looks normal all the hydraulics and coolers are still plumbed in but the column up to the steering wheel looks different and there is play in the UJ where that pin goes through,

I might just get a replacement column with UJs already in to try cure it but can never find them for sale

ok so busy day today before i got the phone call to go into work. spoilsports

woke up to a parcel, its a bag of studs and bolts and stuff fbut i have no idea who from or what for, the only thing i can think of is they are the mounting bolts for my sump brace i purchased off col
but i can\'t be sure, if you sent it though thank you



so i decided i was going to head back into the yard today and clean up the mess that has accumulated around my car, with it still being a live factory and all and me not touching it for months

also gathered a lot of the redundant bits i pulled off the system that i no longer need, thinking off setting up a for sale thread, things like vac tubes and solenoids etc. no use to me, and I\'m sure someone would pay a fiver for a bag of vac lines etc


also decided to try and pull the wings / fenders off to check for tin worm and check the state of the wiring. only managed to get one side off the drivers side lower screws are snapped or just spinning.

anyway get it off and notice something i haven\'t seen on other restorations, my car has some kind of fender brace fitted. I\'m guessing these are the reinforcement braces for when you jack the car up etc







either way RESULT

will be going in tomorrow to measure up some templates for my OMP blanking plates etc
