73.5mm block and Accralite pistons
Turbo Mini Forums

1380cc makes the goods!

togeather with accralite 18cc dished forged pistons from
mr Avonbar


this will puff the T3 up a shade faster and take the camminess out of the Avonbar phase 2
this also with mapped ignition & a Larger intercooler, trick head and exhaust modds.

it should pull the skin off a rice pudding now. ...................lol

will keep you posted!

I'm sure that will pull the skin off several rice puddings !

Very nice piece of engineering. Must be close to the ultimate mini turbo engine.

What head spec / chamber size and shape will you be running with the 18cc pots ?

Keep up the good work, in admiration (much better word than envy lol !)

Cheers

Brocky

BTW - I took my buddy VTEC Pete out for a spin this weekend, and even though I am running her in, he gave it a name, the "Brocket"...cause I'm a brocket maaannn, nah nah nah nah nah nah nah nah nah nah nah....

looks spanking mate.

I'm in the middle of doing me sums to see if i can afford new pistons to go 73.5mm while i'm rebuilding. Looking at using the mega pistons cos i cant stretch to forged jobbies, having a bigger dish machined into em. trouble is it looks like i need 16cc in the piston to get me down to 8:1

What sort of CR are you looking at running mate? i want to run around 15psi but dont know if i need to go as low as 8:1, already got a 29cc head and megajolt, cossie cooler etc.

wasnt someone just saying on another thread that they were running 9:1 on 12psi?

Cant see the pics whilst at work though :(

I've seen the future and tbh its Pie

Where are the undercrown cooling jets Ben?

if you look really close you can see the wall between 2 and 3 flexing already.....

thats before you even run it!

Dont do it m8, your car will set on fire and the steering rack will snap and kill everyone.


*snigger*

very pretty!

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

Ben is that the block you got from moi ? if so i hate your piggin guts !!!!!

just looking at the pistons make you smile ! how much less do the accralites weigh in comparison with the standard pistons ?

also have you put em on pollished rods ?

is that a pre A+ block?

No it is A+, look where the alt mount lugs are.

Its looking great Ben let me know if you need a hand buddy.

good work, glad to see its coming together

is this the engine i funded steve?

looking good. them pistons are just like mine , well actually mine are a little smaller and probably arnt all that shinney anymore

no longer a series, but still 1.3 turbo.

That looks really really good Want to start my turbo build but ive got to build my mini first.

Manchester Minis

thanks chaps

dave errrrrrr.......... no jets buddy
its not a balls out racer would be better to fit some though!

not sure of the accralites weights but........these are quality to say the least even compared to the OMEGAS thes are far superior!!!!

but i have just weighed the 1275 OEM PISTONS with rings and these are 285 grams

with pin 383.3 grams

nic no its not buddy i have incorporated the build into the building work iam having done

its come out of the contractors budget ....lol

no problem tom, thanks buddy just waiting for my machine buddy to finish off some bits for me..but some ones playing silly buggers and nicked the drawings i have given him

so had to measure up again

budd666 8.3:1 at 8:1 you would piss! 18psi wit cooler and mapped

richi no its not you block or crank buddy

yours was sleved only good for a + 40 over bore maybe +60 at a push

Bores gap to next bores look scarling thin....

Looks great Ben. Those pistons look the business and a nice piece of offset boring! The wall between 2&3 looks thicker than mine, what offsets did you use in the end?

oh yeah, duh!!

Looks good! those pistons are a really nice bit of kit,

hmmm, maybe I should go the 1380 route, as I have 3 blocks @ 73.5...

Edited by Joe C on 16th Aug, 2006.

Vrooom they look thin from the underside its a bad pic, look on the block deck pic

spridged the 2 center bores pitched to the outside 0.015"

the two outside bores pitched to the outside 0.010"

this leaves 3.5mm center and the two outside ones 3.1mm

just right but .......... some may disagree?,
most blocks differ! from OEM boring

mini13, "the route to go is 1380+".... if you can ?

1380+ eh?

I do have some S rod too.....

there not there dave cos they aren't needed mate

Best 1/4 mile 13.2 seconds @116 mph

nice job ben those pistons you have did you need to modify the little ends or were they a straight fit.

bud you should be able to run 15 psi with a decent intercooler and good ign timing

im running 12 psi on 9.4 at the mo on mu 1380 and goes bloody well i must say with good mpg.

always looking for them bigger bunches of bannanas

hoggy no, superb fit what an excellent well engineered piston

excellent stuff, pistons do look the dogs!! Like the 18cc dishes, ive use smaller bowls for me cereal than those. Really look forward to the results of this one, all the best.
