a few pics of my friends car
he was going to go down the usual route of 2 litre cosworth turbo engine but i convinced him to use the s2000 engine

Very pretty car! Clean install, it appears.

As a child in the 60's/70's in England, the standard Escort were dime-a-dozen, a normal part of the automotive landscape. Like the Mini, Fiat 500, Volkswagon bug, they are a classic design that stands the test of time, IMO.

about time i updated this a little
ive been busy doing other things that have taken time away from the car but its slowly getting there

checking wastegate height,im hoping the bonnet will shut as the top of the shock banjo i had to cut the webbing in the bonnet for them to fit

need to get a stronger gearbox mount as this one is way to soft

Driveshafts get sent out this week for new custom versions
should finish off the downpipe this weekend when the egt and afr bosses turn up then make the exhaust fit

sold the old ecu and now got another with paddleshift and upgraded memory

quick little update

car is now running and mappedrunning 1.4bar

ive used it out on a circuit and it went pretty good,oil temps were a little high so i have an oil cooler going on

going to take it on track a few more times before i go to zolder in belguim in july
first trial with the paddleshift
trackday
electric waterpump is working well

slowly getting used to the paddleshift and slowly getting used to the car again,steering is still heavy
now running quite a bit of castor on the front so my 17" wheels dont fit in the arches as they catch on steering

Nice update, thanks for sharing @nigel b.

Sounds great. Which brand and control are you using?

Very nice shifter system. Do you know by chance how much torque the Quaife is capable of?

pierburg cwa400.controlled via pwm on the syvecs

Very nice shifter system. Do you know by chance how much torque the Quaife is capable of?

Havent got a clue but it handles how little im throwing at it
gearbox control is done on the syvecs so i dont have wrong shifts for the rpm,xap shifter for gearchange

Very nice approach. How does the ECT curve over load came out? My ECU controls it with a PID controller with 6 maps, among them e.g. pilot controllers for load, VSS, WOT time counter and other stuff to adapt ECT to knock and oil temperature control via oil-coolant-cooler. Works out nicely, from idle till harsch transient WOT I see only +-2 °C. That makes it easier to street tune it.

Thanks, may I have to ask Quaife.

You are a good man, well done engine consolation job! The Cosworth engine would have been a 2-Liter-YB engine? The Honda F20C1 route is a much better fit to the character of this chassis, which is so light in the rear. The torque is lower, but due to the revving capability there is so much power available. Much better turn in control and still fast enough. For Rally, AutoX and maybe slow hill climbs for me the better choice. The challenge to gain this F20C1 over 300 hp is not to high. I pushed the K20 to 310 hp and see potential for 360 hp for my next K-series engine project. The F20C1 engine still has the higher potential regarding peak power.

Yes it would of been the YBT, everything to do with them is stupid costs now.
Bare engine is roughly £8k
Driveability with the s2k is really nice, his one is a stock engine but as the car only weighs 700kg it is fairly quick

Yeap, they are really high quoted and dominated by collectors. I hope this will not happen the next 10 years to the K20 engine. Beside the price, the BDG engine, is really good one. It was used as highly potent 2-Liter NA engine in many race series, also in a FI'd version of the increased 1.8 Liter predecessor BDA for the Zackspeed Capri (600 hp) and has some F1 genes from the DFV V8 engine. The Cosworth BDG and the Opel C20XE are some really nice pre-90'ies engine beside the B-series of Honda, which did not made it properly into the 2-Liter area. B20 has a too low R-S-ratio, which is in the area of the K24, not the best for racing. All of them: BDG, C20XE, even the EA113 from VW made it to 300+ hp in open racing series. If you compare their heads with the K20, you won't believe it. These guy did achieve this all by testing without much simulation, I do today.

My uncle had a competitor chassis of Opel/GM, the '74 Kadett C, which is loved by hill climbers and AutoX racers because of RWD, lightness and good controllability despite the rigid axis with the Panhard bar.

Similar model to the one my uncle had.

I remember the kadett,ours had a vauxhall badge
the c20 let engines used to be a popular swap engine,not as common now but still loved in rallying over here
ford st170/duratec/zetec are also popular still but are low powered

The thing with the k20 compared to the cosworth versions is they are mass produced around the world and they havent got the cosworth name attached to it
The ybt was based on the pinto engine!

Very nice, I didn't know Vauxhall had the Kadett or brother of it also in the program like e.g. the Vauxhall Astra 1st Gen, which corresponds to our Opel Kadett D, which is the successor of the Kadett C. Was there also a sports version like the GT/E with 2-Liter 115 hp to compete against the Ford RS2000?

I love this engine, which is an engineering genius strike compared to the other GM/Opel engines of the 80'ies. Cosworth designed the head, which was and still is the heart of that 86x86 engine.

ford st170/duratec/zetec are also popular still but are low powered

These are also used here for racing in lower weight cars, but not as popular maybe as those are in UK.

That was a high potential 2V-engine, very good R-S-ratio, huge bore of over 90 mm and an high speed capable around 77 mm stroke. A very famous race engine from the 70'ies. David Vizard learned much of his 2-valve head knowhow on that little 2-Liter engine. He wrote in many publications about it and his success in racing with the Chrysler Avenger (looks like a Ford Escort RS2000 or Kadett C Coupe) with a TL16 Pinto engine. Cosworth did now that block has huge potential and build a 16V head for it, which became the YB engine from Cosworth. A very smart approach.
