Difference in Compressor Sizes...

[rn240sx]

Ok here is my question...

The 1st one is a T3/T4 with .48 a/r and st 3 ex wheelThe 2nd one is a T3/T04E with .48 a/r and st 3 ex wheel

I bought this turbo from Adrian @ Fmax in march of 03 and this was the turbo they were using on the 240sx stage 1 turbo kit... I just cant remember what compressor size it was. I checked on turbokits.com and it claims T3/T04E but i dont think thats what they were using back then...Reason why im so curious is cause im running 370cc inj with the jwt ecu. My wastegate spring is an 8lb fixed spring and im reading 8 psi strong at the manifold. I just wana make sure that even if i did have that T04E compressor, im safe at the 8 psi level

Anyone out there purchase the fmax kit around the same time and can vouch for with size compressor they got providing they didnt upgrade from what they offer...

it should be a t3/t04b h trim wheel. Basically a hair smaller than a t3/t04e.If you dealt with Adrian at F-Max then this is the turbo you have.

Ok, i went to the garage to search deep and i found this paper that he had faxed to me. It was a copy of the 240sx sage 1 turbo kit parts list. On it says

T3/TO4B H-3 STG3 With .48 A/R (with a check mark next to it)

So i take is thats the one u mentioned above..??

i understand, i wasnt trying to be a **** man. you never said you called them, so i suggested to call them to get a definite answer instead of waiting for a response on here. but it looks like he is no longer there and you already found the answer to your question. time to change the sig.

buy a wideband (mine is for sale) or get a mdm techdom to calculate injector duty cycle
