| Post subject: | Upgrading to a 6 cylinder engine |
So if no one buys my TJ because it's a 4 cylinder (see for sale section), I'm curious to know what is involved in "upgrading" my Jeep to a 6 cylinder engine. Besides the computer, engine, and fuel pump is there anything else? What about the transmission? Will the 6 cylinder connect right up to it? Any ballpark idea on expense for this type of work? |

Which 4 cylinder do you have the 2.5 or the 2.4? Besides engine, all computers and wiring harnesses, fuel pump, you will also need to weld in new motor mounts, IIRC a new crossmember, depending on the engine, you may need a new bell housing for the tranny, or a new transmission altogether. You'll also need a new radiator, driveshafts front and rear, and if IIRC a new power steering pump. Honestly, for the time effort an money... Forget the 4.0 it's a great engine, but it's performance gains over the 4 cylinder just aren't that huge. If you are going to do an engine swap, do a SB V8. It will be the same amount of work, and relatively the same amount of cash, plus the gains will be much better. **Edit - Looked in the for sale section, you have the 2.4, so I believe you just need the bell housing for the 4.0l NSG370 ** |

I am pretty sure that the NSG370 has an integral bellhousing that can't be swapped??? The 2.4 has more HP than many I6 jeeps. To me, a bigger concern would be the D35. |

I bet after he was down with all of us doing that last lift he just couldn't bear to drive the Wrangler anymore
