Which bore throttle body to buy?
Hey everyone. I'm about to order a bored out TB from stroked jeep. Now my question is which bore do I order? Is bigger better? The intake manifold is only 62mm correct? So going any larger would be overkill? I'm still new to tinkering with my cherokee but am enjoying every moment. Thanks everyone! All advice and comments are appreciated.

Are you still running the stock injectors ? if so, might consider replacing with the neon four hole injectors for better atomization before you go with the bigger TB. Still have stock spark plugs/wires and coil? might consider upgrading to better handle the increased fuel you are ingesting. Restrictive air intake ? stock exhaust? might consider a set of headers before the TB install. A bigger TB by itself will not add the tire melting performance you might expect. It will for sure diminish your gas mileage, but so what, its a jeep! Low end thump is what we are after in most cases anyway.

I might know someone that has a couple used but good condition billet 62mm Rubicon Express throttle bodies that are available.

I was referring to my actual intake, not manifold. I don't do much offroading. Never mind river crossings or anything like that so I'm not afraid to do a cone filter intake.

I sent him an email and he said that he doesn't stock 62mm. So I would have to send mine in, but my jeep is my daily driver and won't be able to send mine. Now I've found a guy on facebook. Good reviews and he does 62mm TBs and it's 110 including a $50 core charge. So $60 when it's all said and done. I'm thinking about going this route
