I rebuilding a 7mgte to put in my pickup. The motor I bought has a hand full of mods exhaust, intake, header, head-mods, Greddy piggy back, big trd cams, MHG JE pistons Eagle rods.

I'm trying to figure out what size turbo I should go with. It had TD07S 25G turbo that is toasted (previous owner) if you have suggestions please let me know. It ll be a daily driven truck I'm only looking for maybe 400-500 HP

 

Gt35r sounds perfect for you. Run the smallest ar. They come with.

 

^ totaly cant go wrong with anything in the Gt series turbos. I have a gt40 on my jz truck it spools great and fast as f*ck

 

^ good price on this one it the same one i have... Garrett GT4088R Ball Bearing Turbo NEW T4 GT40R 400-700HP Precision | eBay

 

i think a 40 will be to big since hes not running a huge amount of boost, thats why i bumped him down to the 35, spool faster and be a lil more efficient.

 

I was thinking a gt35 before I really only want to run the boost at 50-65% of it's max cuz I'm going for reliability... What's " ar."

 

It the rated volumetric efficiency of the turbos 2 sections more or less
