Got my bumpstops where i want them. Now to yank the axles and get em re-geared.

 

 

Just re-reading your build what front bumps did you go with?

THOR intake installed. Renix adaptor and boot mates right to the tube. some slicing and dicing on the bulkhead. Does have an annoying whistle at partial throttle I'm going to have to track down. Had to get a 1/2" PEX tee to connect all the vaccume hoses. not bad overall. much better than the spectre kit. 

 

 

that's going on my xmas wish list   I've grown tired of listening to my throttle body whistle

[WyoCherokee]

Cav-Fab Skid installed finally. took some Grinding and Cutting. not what i expected from the time it took them to develop it.

The smaller diameter daystar ones correct? And how did you get the old one out of that cup? cut it and torch it?

Daystar, Jeep XJ Cherokee front 2" extended 5" tall polyurethane bump stop 1.57" diameter 2 per set, fits 1997 to 2001 2/4WD, KJ09114BK, Made in America , Black https://www.amazon.com/dp/B001GH1OCO/ref=cm_sw_r_cp_apa_i_OQOOCbNJHDMN6

 

Naw, just spray some wd-40 up there, give it a twist and it pops right out.

welp.....long story short, so begins the 4.5 poor mans stroker build.  Had a knock develop one day, got it home and checked for a collapsed lifter..no go, checked for a bad piston....no go. finally just yanked it out and pulled off the oil pan. found a bolt had backed out of the oil pump and got slung up into the #1 piston breaking the skirt all to pieces. I got lucky had no wall scarring and broken rods. I got a friends crank and rods from his 4.2 liter, and will be using those for the 4.5. all the parts are at the machine chop getting cleaned up and prepped for assembly. While i am at it, i am moving the alternator up to the AC unit slot using HO brackets and a zj alternator. additionally I'm getting rid of the EGR, evap canister. i rem oved the entire wiring harness and cleaned the engine bay and re-painted as well.

[WyoCherokee]

Parts have started arriving. 136amp alternator set on a H.O compressor bracket, with some ebay mounts. Will of course have to wire in a external voltage regulator.

any updates?

Engine is just about back together. Summit sent me the wrong valve stem keepers, so ive gotta get the right ones. That's all that's holding me up on assembly.

 

Picked up an HO exhaust header. i grabbed a renix manifold gasket since I'm still using the renix intake. will have to do a little port matching. went with a slightly more aggressive Comp Cam. 68-232-4 if i remember correctly. I want this thing to be a torque monster. I need to drop the tranny and t-case so i can mate them to the engine and drop the whole thing in as one unit.  life has been crazy latelly. start a new job in a month so between packing, moving and putting this thing together.....gonna be busy.

Teaser pics anyone

Well that sure is pretty!

Renix intake, h.o. exhaust header, h.o. head, renix gasket. Minor grinding needed.

Updates: 

 

[WyoCherokee]

Updates coming soon! Truck runs and moves. fighting an extremely lean issue and backfiring. hoping its just my injectors being to small. 4.5's call for 24lb at 39PSI

time to step up the power!

the stock 19lbs are a wee bit small. seeing some conflicting issues in that some folks run the (91-95) 21lb injectors and some run 24lb injectors. so I'm thinking ill jsut start with a set of 21's since they are cheaper and i  can keep em for spares for my XJ.

[WyoCherokee]

Verified i had 703 injectors in there already. So that tells me i need to step up to the 24's.

[WyoCherokee]

Ford Racing LU24 injectors ordered. Hopefully these work! otherwise ill have to go to figuring out the map voltages and wideband

[WyoCherokee]

Injectors installed, i can actually drive this down the road. The off idle torque is amazing. it pulls hard up past 4200 rpms. the old engine wouldnt pull past 3500. i still need to index the distributor per cruisers tips. hopefully that fixes the half throttle backfiring. need to put about 250 miles on it and then change the oil, and then run another 250 miles and change the oil again.

[WyoCherokee]

Did cruisers dizzy indexing. it felt so odd cutting the locator tabs. I still don't know how the dizzy doesn't move.  Makes a huge difference and idles smoother. no more backfiring, and it pulls like a dream. The before and after pictures of where the dizzy should be are really hard to come by, but imagine this....the distributor rotor rotates clockwise. You want to advance the distributor so the trailing edge of the rotor contact is  a paperclip width past the post on the cap. You do not have to cut the cap, i marked on the dizzy with a sharpie marker and used a small straight edge.

here's the best picture i could get.
