just wondering what type of pistons you are using and where you sourced them from?
What compression ratio is this car running?

um yes those pistons arent as flat as the TS pistons im going to use witch drop to around 7:1 as i plan to run 15PSI

Choderboy i would love to know more about your car.

Hey storm,
The factory Autodelta down pipe is 3".
I have a stainless steel 2 1/2" system on it after the down pipe.
The forged pistons I had made would easily handle 15 psi.
When I get the car out of storage for spetaccolo I'll take some specific photos for you if you like. Just let me know what you want photos of.


Sorry i ment piston rings.

Im just trying to think on what exhause i should use on my giulietta i get told all sort of things.

1st i was thinking 3" but iim scared t think it wont fit under the car, so then i changed my mind to twin 1.5 - 1.75" but i am totaly unsure.

im going 3" dump into 2.5" exhaust.
and going inbetween body and rack (body modified to fit 3" pipe), then up along the the driveshaft and out a side pipe.
just and example of what could be done ;)

choderboy, very nice car, i love the old school carby turbo set ups, where does the oil return to from the turbo? directly into the sump or into the block?

pi x R^2

2^2 = 4

2 x 1.5^2 = 5.5

2 x 1.75^2 = 6

2.5^2 = 6.25

3^2 = 9

see what I'm saying? Go 2.5"!!!

Oh - and one fat pipe flows better at high gas velocity than 2 skinny ones even if area is the same....

yes 2.5 has the higher number over twin 1 3/4. I just cant belive the jump between 2.5" and 3" is.

I was just thinking about the twin exhaust as my friend has a similar setup on his 1jz supra and has good power, but then the cost of the exhaust would be double.
