ok so i was reading on scionclub.com or something under the internals thread and some guy got custom rods and pistons to build up the bottom end for a turbo. I remember reading that anything over 6-7 PSI and you risk a high chance of bending rods and stuff. So my question is with custom rods and pistons could i run higher boost and hit maybe 160 whp and still keep reliability of my car, this guy spent 1200 or so on rods and pistons to do a future turbo setup. I know for sure now that i want to go F/I within the next 1 1/2-2 years so this would be the first step? any info advice help etc? im not looking to swap a 1zz either, i want to keep the stock 1.5

 

yes. building the engine = more boost capability. but less driveability OFF boost.. (lower compression pistons means your car is gonna be a dog without some boost)

 

The parts will be stronger, but are they going to be strong enough to over come the problem EL Prototypes talks about:

http://elprototypes.com/1nz%20turbo.htm

These engines were designed for economy over high-performance. IMO, if you're going to spend all that money to build up and then boost an engine, it should be one that is better suited for it. ELP's page does have this listed, but was last updated a few months ago...

4e-fte engine install kit for xB IN DEVELOPMENT NOW !

 

doesnt that engine only have like 135 hp anyway? you can get there with an s/c

 

but if you start with 135ish
then boost it you will end up with 180+

 

I thought 4e-fte came turbo'd already, i must have been mistaken.

 

i think it does, but it has soooooo much more potential...

 

yeah the engine in stock form can take quite a whopping amount of boost..

just sucks to live in cali and have to worry about smog.. w00t for columbus OH and no smog! :D
