ENGINE CONFIGURATIONS
Turbo Mini Forums

well guys after much Deliberation by all, THANKS. on the
CAM CHOICE THREAD. it would be nice for every one to put their engine specs (ie) cam, CCs, valve sizes + types, compression, turbo size,boost ,power,outputs, etc on this thread.continuing from the camshaft choice thread.
it will enable ALL to juggle the configurations and make a better choices for future engine rebuilds. standin 1/4 times would be great also.
BENROSS: :cool:

Well I will put my planned spec up as a start to get the ball rolling. I have got it all now apart from the Pistons that are coming soon. Its not built yet so don't expect any power outputs etc.....

1293cc
15cc Forged Omegas
Group A Head Gasket
27.5cc Avonbar Head
1.4" MG Metro Inlet Valves
Std Turbo Sodium Exhaust Valves
CR 7.0-7.5:1 (ish...not sure of gasket cc or deck height)
Avonbar AR13T Camshaft (similar to Phase 1 I believe)
1.5:1 Roller Rockers
Garrett T3
Planning 12psi Intercooled Boost.
Hoping for 150bhp.

Well mine is still running in at the moment so i've no idea of the power, but as soon as its got enough miles on it the new head will be going on aswell.

At the moment its:
1293cc
11cc 21253 pistons
Avonbar phase 2 cam
ST2 morspeed head (29cc) standard valves (to be fitted)
CR is 9.25:1 at the moment....7.9:1 with the new head (cheers Karl)
Standard T3
Will be running 10psi intercooled

fuck me , i`m shitting myself .
All these high power motas , i think i might as well give up now , before i get blown away by them all.

Everyone knows that instructions only have to be read if the thing doesn't work....

heres my weedy little engine specs;
standard head
standard block bored to 1310(ish i think )
avonbar phase 1 Cam (apparently)
t3
running 6 psi (any more and it pinks its nuts off)
standard box with i assume standard innards
about 90bhp(at TM RR day running 4psi)

hence tital below

no longer a series, but still 1.3 turbo.

Home built engine:-

1293CC A+ block,
Avonbar Phase lord knows what head (its biig chambers with biig valves, unleaded and double sprung and with interesting valves).
Kent K500 cam (road manners)
From MED: Wedged, Nitrided, Crossdrilled lightened crank,
New ligtened con-rods (yay)
Omega Turbo cast pistons (dammit forged are expensive!)
MED special very lght billet steel flywheel,
Billet Centre Main Strap.
Orange clutch diaphragm, organic plate.
Full roating assembly balanced (the rods too)
Uprated cam followers + turbo oil pump.
VP2 Turbo Mainbearings.
Center oilpickup
Escort Cossie mk2 intercooler (sure i can do better?)
TurboTechnics rebuilt hybrid T3,
TurboTechnics 8psi actuator,
Diaphragm Dump valve modded *onto* plenum.
Mechanical boost controller (not bleed valve),
Modded fuel tank with turbo fuel pump and pre-filter(with inetia switch!).
Turbo Electronic Dizzy,
Metro Turbo V-grooved plugs (seem to do the job)
(EMS 5 Boost retard (when i get it set up))
Oil Cooler, Pacet Elecreic fan.
Maniflow turbo exhaust.
Running 8 Psi,

Very progressive and smooth, but needs a RR and some more engine steadies before tuning. But it idles *beautifully* (now)!
