Thread: liners 17mm on the motor SR20

700-800 HP I'd go with the 19mm rod bearings from the GTi-R and have the work done to the main crank bearings so you can run the GTi-R versions of those as well, since they have better oiling capability and might be wider themselves.


Am I remembering that properly? The GTi-R does have wider rod bearings right? Or is it only the main bearings that are different?

Personally, I would not try to make 700 HP on an SR20. I just wouldn't attempt it.

GTIR has 19mm rod bearings Ben. Same oiling holes as 17mm

Mains are the same width for both GTIR and NonGTIR... the oiling holes are the difference.

Nevermind

Thank you-thank you.

Do you know what it takes to get the 19mm rod bearings to work on non-GTi-R stuff?

the rods need to be machined to accept the 19mm rod bearing. Most any machine shop can do this. Some of the higher hp rods come machined for the 19mm bearings.
