Some vids of the pretty much finished truck!!


PM me for a list of parts. I also build swap wiring harness and pedal brackets!

drive by exhaust sound clip


shifting and cruise switch

cruise switch and whistle from intake not heard on video.. I heard it tough!

Special thanks to Current Performance and all there help on this project!!

Well after years of thinking..months of planning and thousands of dolars later, I am ready to go for the real deal! Today I started pulling out the old 2.8L 4 banger to make room for the 07 LS1 converted to LS2 4.8L V8. I still need to get lots of things but basiclly here is the list of what I have;

- 07 GMC savana 4.8L engine 13,292 kms
- Cp perf. engine mounts
- luk LS1 clutch Zo6 preasure plate, ARP bolts
- LS2 knock sensors
- 2006 SSR computer & gas pedal
- HP tunners
- E40 computer plugs
- bracket to mount trailblazer pedal
- advanced adapters bell-housing to mate jeep AX15/Colorado MA5 tranny to V8

Update Jan. 2nd 2010

And it runs!! Boy did I get a lot done in one long day! a lot still needs to be done, and some stuff was really "thrown"together... but it is a ""start"" anyway no pun intended!

Today I installed the LS6 valley cover, injectors intake manifold throttle body, finished up the wiring harness connections, made up the fuel lines, heat wrapped the wires and clutch line, installed the van dip stick, changed the filter put 5 quarts of oil in, battery cables (temporary)

Some issues electronically the gas gauge reads reverse.. no surprise, and for some unknown reason it says change oil???


Also added this to the first page.





The first vid is boring and not recomneded it is just a reference of all the gauge funtions etc.. and the stock truck running for the last time as a 4cyl.


here is some pics of my progress tonight lol 10:00 PM to midnight!

here is a vid of the progress tonight, lots of plastic crap on these vehicles today!



Update DEC 02/10

Well guys here is my progress from last night and tonight. Off the top of my head here are the issues;

- need different exhaust manifolds or some headers which ones?
- need transmsison bellhousing sapcer and longer pilot bearing, slave spacer?
- need to notch or hammer the firewall lip to clear the intake manifold or use a LS1 car intake
-I had to notch the bellousing for the starter and cut holes an notch for the slave cylender lines


I mixed the egine mounts up would have been nice if they were marked, add the pull engine and reposition, next time I will remove boht exhaust manifolds for clearance it is a tight fit! FYI easier to mount the engine mounts to the frame then drop the engine in, also easier to remove the passenger coils as it is tight against the heater outlets. The oil pan seems like it will work, just hangs down a little I don't think it will hit anything.

Here is a couple of vids first one engine removal, second one comparing bellhousings third one first fit up of the V8





Update DEC 13 2010

Well I took some pics, the proper way then engine mounts should be, and pics of the 06 GTO LS2 intake & fuel rails, 06 SSR throttle body, stock colorado fan clearance, and 06 OBX Trailblazer SS header fit problems; passenger side motor mount had to be cut about 1/2" on the back side, drivers side contacts frame, brake lines, steering shaft etc.. I had to bend the coolant crossover pipe down and over a bit to get the LS2 intake on, however there is now lots of space between the firelwall/cowl panel now!!

Re: making room for a V8 engine 4 banger comming out!

First eight pictures of the front of your truck are intense man! lol

Good luck on your quest
lol ya I might have been a bit excited, I will prob. slow down on some of the pincture taiking as I get going, I will try and take lots of the V8 going in, and any changes

Very interested in all of this, so thank you for the updates, vids and pics. Cant wait to see that baby run.... Just realized how close you live to washington state. I am in Port Orchard. When you get this thing rolling, I would love to see it in person. (Spring or summer) Maybe another NW meet or something. ..
Sounds good, I hope to get it done, for the NW met.. hopefully I don't run into any snags! Port Orchard is how far from bellingham? I go to blaine, and bellingham WA. for parts all the time!

Awesome best of luck man
Can't wait to see it done.

Thanks guys.. I can't wait to so it done as well!

HI, what gets converted to make a LS2 ??????????????
computer and computer plugs, LS2 knock sensors and LS2 knock sensor plugs, rewire 8 pin throttle body to 6 pin LS2 harness. I am getting code P2119 for throttle body though, I have a 4 bolt 6 pin LS2 06 SSR throttle body on order we will see if that makes a diffrence

Re: making room for a V8 engine 4 banger comming out!

What diff is there over a stock V8 computer setup from the factory.

Re: making room for a V8 engine 4 banger comming out!

I so wish I could do this myself....and that I had a garage to work in, lol. Gravel driveway swaps are not always the best when you have to work alone ;)

Re: making room for a V8 engine 4 banger coming out!

Also the LS1 was a 5.7 and the LS2 was a 6.0.......but the 4.8 is an LS based motor.

Re: making room for a V8 engine 4 banger coming out!

What diff is there over a stock V8 computer setup from the factory.
The factory uses a E67 computer Late LS2, I think LS3, LS7 as well, and what you get if you by GM performance LS2 computer and harness kit.

The E67 while not imcampatable would work with an older colorado 07' and down it would take alot more wirring then I am allready doing, The E67 is better suted for a 08' and up colorado.

Also the E67 uses 58x ignition, and my engine, as well as ls1, early ls2, pretty much all trauck engines 07' and down use the 24x ignition, and the two are not at all compatable.

What I like to hear man
yup gonna hopefully be the first V8 swap using the stck 5 spd!


those fans are a BITCH to remove! luckily mine was already busted so it made removal a tad easier

nice progress!!
Why did you remove your fan?

Haha!

Well my son is going to be born in the next 2 weeks or so............with that said its back burner for the time being. Once we have 0 debt(which we are close too) and have bought a house it will be game on!

But I held off because its going from a 5.3 to a 6.2 ....... Also the LS1 was a 5.7 and the LS2 was a 6.0.......but the 4.8 is an LS based motor.
haha if I new that I would have bought your 5.3.. maybe unless you are making a stroker out of it? LOL I don't know what to call it your right it's not a LS1, but verry simular electronically to a LS1 I spose it would technically be a Gen 3 vortec engine? Dosen't sound as good does it.. oh well! Hell I think I will name it frankenstine after all the wirring mods I've done to it, it is someware between a LS1, LS2, and a Vortec engine??


I so wish I could do this myself....and that I had a garage to work in, lol. Gravel driveway swaps are not always the best when you have to work alone
lol paver stoness and a R/V tarp = propane heater = red necks garage! I wish I had a bigger garage at home, so I wouldn't have to comute to work on my truck.. oh well at least I have a warm dry somewhat flat surface!

Re: making room for a V8 engine 4 banger coming out!

What's everyones take on electric vss. mechanical fans? I hate the sound of e-fans when ideling my 94 Z28 had them and it was anoying as hell. I know a mechanical fan eats a little power, but like what 5 hp tops? or is it more than that? Obouvsly the reall deciding fact will be if a mechnaical fan will even fit, with a V8?

back off to the shop! I got the rad pulled, intermedate pipe, drive shaft, fuse box, computer, tranny, center console, gas lines, heater lines all out! Hopefully I can yank the engine out tonight!

Re: making room for a V8 engine 4 banger coming out!

e fans just to save room and then you know they will clear unless u get a v8 colorado mechanical fan. imo go to an electric.
Good point
