my car started off as a 1.0 45-s with only 10k miles on the clock, I reshelled my old uno turbo which was too rusty to carry on in to it, I have learned a lot whilst building it and have enjoyed using it in the summer, it made it to the nurburgring and back with 8 laps done. also a couple of trips to santa pod rwyb day where I managed a best time of 13.5@ 105mph,

the current engine spec is

standard 1301cc bottom end
standard head
piper 270 fast road cam and adjustable pulley
garret gt2554r roller bearing turbo
walbro 255 fuel pump
pace alloy intercooler
330cc injectors
punto gt management mapped by fcp in bristol
stainless steel exhaust
K&N air filter,
inlet manifold has enlarged throttle butterfly

future plans are to uprgade the engine with head work or building a larger engine either 1.6 or 1.9 sohc to make the car better to drive as there isn't much power below around 4krpm due to the turbo lag

I am now the proud owner of a GC 1.9l stroker engine

the power and torque is just brutal and is a massive step up from the old 1300 engine, I have done a excel comparison and the new 1900 has more than double the power in the mid range, peak is 302bhp and 303lbft of torque

engine spec is
GC 1864cc stroker cr 8.3/1
piper 270 camshaft
gc spec cylinder head with 39.5mm inlet valves 33.5mm exhaust
arrow precision con rods wossner pistons
garrett gt2560r turbocharger
bosch motronic 2.7 ecu
siemens deka 630cc injectors
walbro 255l fuel pump
radtech alloy radiator
pace alloy intercooler
mocal lamionva with remote mounted filter,
racetech oil and coolant gauges

Thank you GC for making it happen.

Amazing and i bet that would be absolutely awesome to drive. Wolf in Sheeps clothing just great.

I notice you take it on circuits, what do you do about oil surge etc. Do you run a baffled sump and or oil accumulator to make sure damage is not done in the twisty stuff causing surge?
Be a shame to wreck such a great engine.
Definitely see alot of work has gone in.
Enjoy the results

Just the standard sump is fitted, Guy has told me to fit an accumulator, which I will be doing very soon before it goes onto any track, there isn't much room left in the engine bay so I am going to try and conceal it in the passenger foot well or tucked behind the dashboard.

Hi Mark,

I see that you use a laminova oil cooler. Can you share your oil and coolant temperatures? Do they remain within the desired operating window under all load situations? (75 degC coolant and 85degC oil)

Best regards,
Charles

Yes I use a Mocal Laminova, its the medium size one which is supposed to be equivalent to a 16-19 row air cooler, so far I have never seen oil temps exceed 80 degrees and the large alloy Radtec radiator I am using keeps the coolant in the mid 70's and only creeps up to 82 when stationary then the fan turns on. I am yet to take the car on a track where I will find out if the cooling system is up to the job.

Before and after comparisons, superb photos, detailed spec, response to feedback....

outstanding really and what this forum is all about...

I'm so pleased to have been part of this with the talented, skilled and well-informed young owner Mark S Beresford, without whose amazing knowledge of the donor parts (crank, block, head to name but three) I would have been 'lost' with this engine!!

Well done MB!

Retro Show 2019 I competed in the 1/4 mile run what ya bring Class C which is road legal tyres and under 2000cc with turbo or nitrous and won the class with a best time of 12.9@109mph, my friend Ben in his twin cam 8v powered white uno which you can see below set a best time of 13.2.

Mark,
that's brilliant, the car looks and goes awesome. I really like the "clean" look for the unsuspecting.

Regards,
Steven

I have wanted to get the engine to run at 74 degrees for a while as the original thermostat is 82 degrees, I tried drilling a hole in the housing which allowed the engine to run cooler on the road but on the track temps were around 80, drilling the bypass hole out larger just made the engine run too cool on the road,

I eventually found a 74 degree thermostat which fits into the housing and works perfectly. First line Part number is FTS104.74
