The first (and last) person to ever turbo their 5S-FE boosted so strong that the car dissipated and allegedly went back to the future.islandmr2 said:Hey guys, I am a little new heree and I have a big question, what would it take to boost a 5sfe without swapping the motor? Can I keep the same head and get a custom intake and exhaust, or need a head swap. All info would be great. Thanks
what he said.. high compression + high boost = failure with that setup.billwot said:The 3sgte was designed and built for forced incustion. It has all the appropriate sensors and controls, and the ECU is programmed to control a forced induction setup.
The 5sfe was never intened to be FI, does not have the necessary peripherals, or proper engine management.
So why don't you just do a 3sgte swap, and take advantage of the original Toyota engineering?
It has higher compression than the 3sgte.Epic| said:It's not compression. The 5S-FE is not a high compression engine. The problem is it's an economy 4 banger. Can it be made to work? Yep. Can it make good power? Yep. Are you going to break it? Yep.
I agree, you didn't compare the 5sfe CR to the 3sgte CR...but I did. :smile:Epic| said:I said nothing relating the 5S-FE's compression to the 3S-GTE's.
