HI Gareth,

Here is the thread on TurboSport where the guy kept the original inlet etc - http://www.turbosport.co.uk/showthread.php?t=164271

Though he only did this to be eligible to race in a rally series he was in. For the work and cost involved in making the OE system work, if you are considering changing to throttle bodies/carbs in the future it would be better to do it now, but this is purely my opinion :)

Kind Regards

Joe

Thanks Joe. I will have a good read at this. 👍

As I said in my message Gareth, bike carbs are nice and cheap, should be able to get a decent set for around 100 quid. Manifold will be the pricey bit, but people have used the ST manifold and cobbled it together with the existing rubbers.

Agree with Joe though, if you're going to do it, do it now........

Hang in there dude ;-)

Lol 

i bought the jenveys for £120 as no one else bid came with rails and throttle bracket not sure where to put the injectors yet

If mainly a road car, injectors as close to valves as possible - Track car or lots of high rpm use then further away will be of benefit.

So progress has been slow mainly due to getting the funds together for this. Combine this with the fact that brexit has added some additional shipping costs has meant I'm waiting to get all the money together then putting in 1 big parts order. I've been speaking to Dave and Luke at retroford (big thanks fellas) and have pretty much agreed on their stage 2 fitting kit with some additions. Swapping the flywheel for their lightened version and added in the atlas lsd. I've also started on getting the fuelling system started. 

The ST170 engine has been stripped and the block has been cleaned and painted. Just waiting now to get the breather on the rocker cover moved so I can paint it up. I hope to have a big update in about a month.

Looking good and got to smile at the line projects always take way longer than planned, I am on yesterday eight and always say the same thing - next summer 

 

always worth it in the end just, quick picture of my bay with the ST170 sitting nicely at home - running emerald ECU which is about to be upgraded to the K6 so I can run the VVT the way it was intended

That looks sweet as donka! Im loving the carbon fibre effect rocker cover and cam pulley cover. I'm painting my rocker cover orange to (hopefully) match the body colour and was considering running no cam pulley cover as im putting on a vernier exhaust pulley to try to eke out those extra few ponies. How do you find the 170 lump for smiles per mile?

She stated life in an estate, previous owner (Paul) spent a lot of time and money on it. Engine was built by Northampton Motorsport and it pulled like a train when in the focus

she still isn’t running in the escort yet but not far away as I have an electrical fault I need to remedy once I find it, hopefully it’s just the crank sensor as it doesn’t go green when cranking but just as a precaution the ECU has gone back to emerald for a health check as it’s been in the garage for nearly 8 years waiting for the transplant to be completed

I changed the standard Oil breather system for something tidier so need to see how that goes as I have seen some good feedback and some not so good. Worst case I will weld an AN fitting onto the original breather and retain it 

Routed the hose behind the engine next to the bulkhead, below the ITBs and into the catch tank, then it was drill a hole in the cam cover and connect to the tank, system complete I hope 

Used AN10 fittings and hoses just to keep it all the same as the fuel lines were all black braided lines as well but AN6 for the supply and return with AN8 from the tank to the pump

Amazing! So 8 years then to get your build complete? I'm hoping thats because you have done a complete restoration and not just an engine transplant! 😱 looking amazing though.

I've heard it takes serious money to get those ST170 engines over the 200bhp mark so for that one to make 215 it must be amazing! That will push your MK1 along just nicely! 😜

She started life as a black rs2000, the like many she must had had a shunt and was flat fronted. She then moved on and was running a cosworth till finally being totally stripped down and rebuilt from a bare shell with a vision of having a standard looking RS outside and inside with everything else modernised so starting at the rear she has a baby atlas rebuilt by RACE running an LSD, discs and cosworth rear callipers, type 9 gearbox rebuilt with taller first gear, heavy duty bearings and bigger oil ways, engine built by Northampton motorsport with ported head, piper BP300 cams, variable exhaust pulley, vernier pulley, competition rings, lightened and balanced crankshaft, puma speed oil pump, aluglide big end and main bearings, ARP bolts all round so well built
