I like and I don't like the spot for the trans cooler! Its a sleek heat resistant spot with airflow and tucked away, but at the same time.. Don't break a u-joint.. Its a toss up. Killer look with the LS1!! more pics!

... I did not have much choices to fit a standalone 10"x13"x5.5" brick somewhere ... and the derale direct fit kit is even more exposed I think.
I might think about a special skid plate ... or cage ... for that thing (if it can be helpful with a grenading driveshaft )

Oh ... more pics will come for sure

... actually shame on me ... it is not all DIY ... (actually most of it)
I did the reading, collected the right parts, did some decisions and am regularly checking on the progress in the workshop (yeah ... they like to forget about some details)

and regarding the drool soundclip :
I will upload once done

regarding exhaust I am more than curious as well ... a magnaflow Y pipe 2x2.5" to 3", a 3" moroso spiral flow as resonator and then a Magnaflow 12589 muffler.
The muffler body is quite fat and a tight fit (5x11x22) and I hope for a mellow "sleeper" growl and not too loud

Are you finished with the exterior? It looks good as-is.

exterior mods are not planned at the moment ... just a grille mesh and some small V8 decals on the sides maybe ! lol
Thanks

BUT drivetrain mods ...
Vanco 15" Big Brake (WITH BM pads) conversion recently done,
TNT rear upper spring relocation plates are already here,
Superior D44 bolt on truss already here,
Currie Arms,
Bilstein 5160's (for 3" lifted TJs),
Currie Trackbars,
and Currie Anti Rock
are on the way!

and hopefully the new Savvy modular UA (super drool) soon

hmmm .. just to give you some background infos how everything started 1 year ago:

last year i figured out i want a gm swap after finding out that magnums are only straightforward with older TJs because of dash bus and evap incompatibilities with newer TJs. Hemis would be plug and play with 05/06 TJs but here in the UAE a expensive and painful odyssey.

so in october i could make a good deal on a ls1 donor ... and started digging all information (plenty on pirate!) regarding 5.3 swaps (equivalent!).
Decided to go with ONE swap specialist to collect the conversion parts ... and Novaks website is generously informative and Ryan was great to deal with ... so I decided Novak it will be.
Tranny to TC adapter, mount/isolator, radiator/fan/shroud combo, headers, accessory relocation brackets (KWIK), engine mounts (not used in the end bc of strict frame no mod regulations here), Lokar cable operated transmission shifter, cable operated TC shifter, tach emulator box to run the last missing gauge through the retained jeep pcm and some intake tubing all ordered from Ryan.

used the elapsing time to figure out i need a fresh new standalone harness instead of modding my old dusty and dry donor harness ... so i ordered from speartech.

then until everything paid and arrived i figured out what exhaust and how i will run it ... and ordered some parts from summit including radiator hoses, clamps, bungs and fittings, Lokar shift indicator/switch kit ... plus a superior D44 bolt on truss to reduce axle tubing flex due to torque ... will save my diffs for a while i figured.

chromoly shafts front and rear and truetracs full carrier lsds plus inner sleeves for my front D30 were already in since my regear early last year.

then ... 3 weeks ago the build has started ... 4.0 I6L plus 42RLE already sold for 1700 USD ... remaining donor body sold for USD 500 ... so LS1, 4L60E and GM ECU plus all accessories and sensors cost USD 800
(complete donor was just USD 3000)
in total including labor I will have 6.5 k into the LS1 swap excluding the drivetrain mods to come.

regarding the donor pcm:

you need to reflash donor pcm for

- disabling VATS (security)
- disabling rear O2s
- gear/tire size adjustments
- eventually shifting behaviour/torque management
- eventually egr delete
- eventually evap delete
- eventually manual gear tune

the first two are the most important to get thr engine running!
the rest is to get it driveable

actually with HPtuner or EFIlive a matter of minutes ... or you can get the service done for you ... wayne hartwig at pirate4x4 offers pretuned pcms for cheap or a reflash service for yours ... but his tunes kick axx power wise as well.
( you need a built tranny and a bit more than a D44 in the rear to run his top tunes )

I got HPTuner and did the essential stuff myself... and will run stockish power and shifting with my beefed up D44 and still LP D30.


sorry for the long post ... only to illustrate that a slow approach is helpful to reduce down/build time of the TJ

small update ... not much done, but thanks God ... a bit:

Did I mention they started to mount the LOKAR cable driven automatic transmission shifter ?
Now it is in place ... just needs some adjustments and the electronic gizmos like my new digital gear shift indicator and park neutral safety and reverse light switch (and the manual shifter boot )
lokar_tranny_shifter.jpg


This is how low the engine is sitting now ... and how low the rad is located as well ...:
rad_engine_low.jpg


and finally ... did I mention what the biggest problem with beefy e-fans is (and especially here a la mussaffah fab) ?
exactly ... the RIGHT wiring harness (gauge!) and the CORRECT relais for the high ampere draw:
(note the huge NON mussaffah relay and the right fuse )
frh-ho-kit.jpg

(missed to order that from summit, bc not available from them, BUT luckily mebar-auto/Dubai had the right SPAL FRH HO kit on their website ... ordered thursday and minutes ago the courier dropped it at my apartment ... wow, GREAT service!)

my time table is already messed up ... but there is still enough to drool on

the closer we get ... the slower

here some pics of the "work in slow progress"

1. steering box reservoir from a Holden Monaro (Lumina SS, Pontiac GTO) mounted beside the rad where the OE coolant overflow bottle was.
The guys at the shop did not want to mount it to the block/Kwik brackets to avoid steering fluid dripping on belt/pulleys (in case).
steering_reservoir.jpg

2. intake with original donor MAF sensor ... seperate IAT sensor is going to be attached to the aluminium tube (older LS1 pcm/harness pre 2002 had 3 pin MAF and separate IAT). Custom coolant overflow reservoir is going to get attached at THIS side of the radiator
intake_maf.jpg

Speartech harness is beeing worked in at the moment ... pcm is going into the cab below drivers side dash to the furthest left side wall of the tub. No pics yet ... but soon.
Standby with my adjusted base tune to flash in. graaahhh

still to do :
- shifter adjustments
- brake/TC lockup switch mods (reverse logic! GM needs ground when brake pedal down, Jeep logic +12V!)
- gear shift indicator Lokar CIND 1725 placement in front of shifter boot

- backup light connectivity from my Lokar CINS 17002 sensor kit
- park/neutral safety switch output from Lokar CINS 17002 to jeep pcm connectivity
(both according to the TJ wiring diagrams easy to splice into the connector of the OE 42RLE transmission range sensor connector ... but park/neutral has reverse logic! GM uses ground ... jeep uses +12V)

had to copy the right pages out of the FSM and drop them at the shop ... The guys are more GM specialists and needed a helping hand ... LOL (I am not completely passive)

- electrical wiring of the Derale 13960 primary tranny cooler / thermo switch placement
- efan electrical wiring / Spal FRH HO kit
- exhaust stuff
- A/C electrical connectivity and piping/dryer! (the electrical stuff will become interesting as well)

Announcement of Birth



My V8wannabe is not wannabe anymore
Please welcome Sluggy which stands for "Sleeper Juggy"

Today at 8:57am I got the SMS from Dr. Hisham at 7performance that Sluggy is alive and healthy ... a first strong cry cut through the sleepy garage this morning.

A new interesting and challenging phase has started:
Sluggy needs to learn how to get nursed. Changing diapers needs to be learned by me. We have to go through the difficult and sleepless time of teething ... and we have to go through all the vaccinations to prevent any serious illnesses.


The story:

Tuesday evening the engine harness was completely worked in ... pcm got programmed by me with a first basic tune ... we turned the key from Run to Start ... and ..................... nothing
(( I immediately remembered that for the Jeep PCM to turn the starter (Yes, Hisham wired the V8 starter to the stock Jeep fuse box!) the Park/Neutral signal of the auto transmission has to be set correctly to the PCM.
Fortunately the stock transmission range sensor connector was still somewhere below the tub and after identifying the right pin and grounding it the Jeep pcm could crank the engine ... cool ... but
still no ignition )) EDIT 16.9.2012 : meanwhile the fuel pump relay is driven by the GM PCM ... this is how it should have been from the beginning!

After checking the crank position sensor plug(good) and fuel delivery(good), Hisham started to disconnect the GM pcm to check the harness pinout and connectivity ... and I left the garage ... slightly emotional.

Of course I had to dig the wide web for similar problems ... and one "other" reason for cranking and not starting turns out to be the wrong connection of the harness "Ignition 12 V" wire! (The direct to battery 12V was fine)
Some guys were loosing the 12V after they turned the key to start ...

So Wednesday afternoon I visited the shop again ... and gave Hisham this hint among some others.
Late in the evening a phonecall with Hisham... BINGO ... Hisham confirmed he experienced Voltage loss at some engine plugs after turning to start.
But of course the battery meanwhile was drained ... so he had to connect a charger overnight.

Today in the morning ... the happy event

But to adjust expectations ... NO ... I am NOT joining a trip this WE ... still lots of "clean up" TBD ... the ToDo list of previous post is mostly still open!

But getting close

Thanks!

re "jealous": I was for a long time too ... reading about all those swaps in the different forums. So last year I made a move and started collecting "parts" and spending money ... a bit at a time ... so the spending was stretched and less painful.
But I can assure you: there were quite some moments where I was concerned if I ever will complete Sluggy successfully. But the more I spent the more determined I got.

Now I have to sort out all the minor bugs and make it a reliable full time DD and off road toy.

Good luck with yours and keep it up!

Welcome to the club. Very similar progress on mine. Just finished it last weekend. The small things really seem to bog down the swap but it is worth it indeed.

Thanks!
patience gets tested ... and homework has to be done!
can't wait to experience the "difference".

EDIT: just went through your build thread ... nice! (you are ahead with the rest as well ... LOL)
