hi guys...
im in the process of installing a new front mount intercooler. and was just wondering what the outlet size of the td04 is on a 4g61t... and the intake size... i thought it was 2.25 but after looking online im coming up with different measurements all over....

thanks

hey i just measured it and it seems to be 1.75 inches but i thought it would be 2.25 (measured with hose on ... idiot)

sooo my intercooler has 2.5 inch inlets... what i was thinking of doing it simply running 2 inch piping but at the outlet of turbo and intake ill have a 1.75 - 2 inch reducers and at the intercooler 2 - 2.5 inch reducers....
would that be to much of size changing or should that be fine?
is there a mod i can do to increase my intake and outlet sizes?

for example i was thinking of getting some pipe expanders and expanding the outlet of the turbo to 2 inches but iam unsure if i could do that with the intake to?

thanks

the stock J pipe coming off the turbo is 1 3/4" inside diameter (I have the pipe and turbo in front of me now) and the intake part going into the turbo from the air filter is 2"

my setup has the 2 1/2" IC piping also... I have a 2' to 2 1/2 coupler at the J pipe.. and all my ic pipe is 2 1/2.. it is loose fitting but I used 2 clamps and it seems to clamp down good and hold 16 psi.... but im sure you can buy a 1 3/4 to 2 1/2 coupler..

hey thanks for that.... so do you think stepping from that to a 2 inch piping then to a 2.5 inch intercooler is ok or is that a bit to big?

NEVERMIND!
you answered at the same time

by the way what about the pipe expander idea?

I personally wouldnt do it.. to many connections = more places to leak.
I would try to find a coupler either 2 to 2 1/2... or a 1 3/4 to 2 1/2..

slowdsm
do you mean run 2.5 piping all the way through to the intercooler?
so you think get 2 - 2.5 couplers as for the outlet on the turbo and the intake manifold... i cant find any 1.75 - 2.5 reducers... thats why i thought of expanding the pipe that little bit if it goes....

I am trying to avoid to much lag by pipe sizing if i can


one option i was thinking is...
get silicone reducers from 1.75 to 2.125 (all i can find)
stretch the 2.125 over the 2.25 (i think itll stretch)
run 2.25 piping to the intercooler go from 2.25 to a 2.5 then out of the intercooler go 2.5 to 2.25 then run back to the intake 2.25 all the way and use a reducer again 1.75 to 2.125 and stretch it over....

i was hoping that minimizes lag?


other thing i could do is expand the outlet of the turbo to maybe a 2 inch (i still dont know if i could do that never expanded a pipe but i found these on ebay http://cgi.ebay.com.au/ws/eBayISAPI.dll ... 1005098541 and thought that might work)

then go from 2 to a 2.25 run 2.25 pipe all the way through and just get reducers from 2.25 to 2.5 on the intercooler?


or does the pipe size from 2 to 2.5 not really produce much more laG?

yeah come off the turbo with a 2 to 2 1/2" coupler..then run 2 1/2" pipe to the IC and up to the throttle body...the 2" will clamp down onto the J pipe good just use 2 hose clamps on it..

this is the J pipe.. as u can see there are 2 bumps.. put both clamps in between them and it will seal up good..

as for the intake.. u can make it however u like.. im going from 2" up to a 3 1/2" filter.. this is not as crucial as the IC piping so you can make it however large you want to.. alot of people use a 4" filter

this part correct?..

if so most people upgrade to a 2g dsm one which is 2 1/2..

thats the one .......
2g dsm u say?
whats that part called? and where do i find one in australia ?
if i call a wrecker what car is that out of?

would a bigger throttle body be an idea with that or not worth it yet?'
such as this 1

thanks

stock throttle body is good..

part is called a throttle body elbow.. the 2g dsm is 95-99 Mitsubishi eclipse/Eagle talon.. with a 4g63t engine.
