yes they will all fit. if you look at your block you will notice that the block is marked 4.8/5.3 the block is the same so all external acessories should fit. i have the lm7

vinhZXT, do you have any recomendations on what to do about that ODBII connector? it would come in handy. do you have yours connected? and if so how did you do it.

yep, that was really my question, could you make it work for a 5.7? i would really save me some money.

Has anyone done anything with a 3.8l regal supercharger? they are very cheap in the jy.

would someone mind telling me what years of coverage for that taurus fan. i found a few but they are dual fans.

is the engine physically the same size as an ls1? are you using the JCI mounting kit?

great idea thanks

Getz, thank you. exactly what i was looking for. Johnc, thank you. info i needed and didn't even know it, i searched "coil overs" and "install coil overs" but did not see this tutorial must have missed it but thanks again. David

guys, I have been searching, and i feel i have found tons of useable info but i still have a few questions. I found these on ebay i visited the thread that gave the suspension upgrades in stages, and the only real reason i feel the need to switch to coilovers instead of just freshening up my suspension is wheel size flexibility( I read an awesome thread where a member is using 18" wheels) any way here are my questions: any one have pics of the coil over swap process? is the orig coil spring seat the platform that holds the threaded portion of the above coilovers from slipping down the strut body? if so do i have to trim the (width)seat down? i have not disassembled the orig strut yet, is the top threaded so that i could install a replacement cartridge? if so, why all the talk of welding? what is everyone welding? if not, even with all the talk of welding how will i get the top of the strut housing threaded? if someone can answer these questions i think i will be able to continue on my own. thanks in advance

thankx

what is the name of the product you used i am very interested.

well i am doing the same swap and my throtle body was drive by wire. i have retained the drive by wire feature because i am using the original harness otherwise the throttle bodies are the same size. i know because i purchased a ls1 throttle body spacer and i fit perfectly.

good job!!! That looks great ...would love to find out more about this swap. Elaborate! how did you do it? are you using Ls1 acessories like water pump? i notice you are using the ls1 intake. i am doing the same swap ad would love to hear more about it. Keep up the good work

Milesz, I am at the same point as you are in your swap and i am swaping the 5.3 4l60e into a 75 280z. I just finished extending the wire harness and figuring how to match it to the OEM 280 harness. I have not gotten my JCI kit yet and was just wondering how you cut that tab off of the right side where the a/c comp. mounts since our blocks are iron? according to everything that i have read that is a requirement for mounting the JCI kit. travrmk....you will need to use the lsx intake the injectors will not work so try to get the intake, rails and injectors. Oh, by the way the coil packs from the truck engine gets in the way of the fuel rail so get those also.

which mounting kit are you using? JCI?
