running a T3 - engine
Turbo Mini Forums

ok this might sound stupid but im gonna ask anyway.

from what i read, the T3 doesnt kick in untill 3k ish revs. so untill then, it drives like normal, right?

and its not like you HAVE to heavily mod the engine if you dont use much psi.

so based on all that ^ you can use pretty much standard internals. i know this probably been covered many times before, im tryin to convince myself into doin it without breaking the bank!

mic , a t3 with a stockish low duration cam will start to work at around 1800 rpm .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

IMHO if you run stock boost, you could run standard internals (ie non turbo) with no problems, and for long peroids, with carefull maintenance, however for added security i would still use an intercooler :) the killer from what i have heard is not getting CR right and fuel octane levels, both are crucial or the dreaded detonation occurs.

i think there are a few peeps on here who have used stock N/A blocks n pistons etc and ran high(ish) boost without issues, just got to do ure homework. you could run stock block and lower the cr by getting the chambers cut from BENROSS, this is not really an expensive mod (in the grand scheme of things) run 4 - 7 psi max boost with a cooler, keep everything else stock, u should be ok, but if you intend to 1/4 mile or throw the car around, be prepared for diffs and drop gears to eventually fail.

remember cheap build does not equate to not doing homework after all research costs nothing and can save you big bucks in the long run.

Hi,
What Richie said really. I'm going to be running 10psi on a stock Mpi engine and box, with IC and mappped ign.
This will push the box and drops to their limits. Don't leave home without a X pin diff though!
Cheers,
Gavin :)

My Mini build diary

i think this all comes down to how your going to drive it, ive stuck with the standard SPI gbox (rebuilt) and uprated my diff pin and planet wheels. i think this will be plenty strong enough for me running a max of 10 psi.
mines a daily driver and i dont think im colin mc crae though, but if your taking it on the track i would look into a few more mods.
only my opinion mic

'always keep a spare shot for a stray bird'

I'd be interested to know what BHP is coming out of stock(ish) lumps with the turbo between 7 and 10 psi max boost. Anyone tell me?

It's all fun and games until someone gets hurt... Then it's hilarious!

stock BHP from factory was around 90bhp that was with boost at 4psi i believe

my first proper turbo lump was stock ish. only had a rebore to 1293 with ae pistons and a ph2 cam, was running 120 bananas on 10psi and i think the last time i had it rollered it was 135 bananana's and 165 curly's at 15psi.

when i had my stock turbo lump dynoed it only made 81 bhp at 7 psi but 101 ft pounds of torque, completely standard

i also make things

i love coming home to chrome

I can't see the being a problem using standard internals upto 10psi.
