Finally my build thread worthy second stage has started ... after I got my latest TJ in 2010 and modifying it a bit (see my profile) I pulled the trigger for the power train upgrade
This was my toy in 2010:
after several bolt on softcore mods it became like this:
and this is the main play ground on weekends, a big sandbox
(during the week a street legal and well maintained daily driver!)
All powertrain day dreams started after some nasty experiences with my so well hated auto tranny (42RLE) in steep off camber situations, either not shifting fast enough, or not shifting at all or loosing the lower gear and stuttering between 1 and 2
So ... a long read and research excursion started ... the only reasonable alternative of swapping a AW4 in (yes I wanted to stay auto!) was quite expensive because of new manual PCM, solving some CPS issues and an getting the right parts (low mileage AW4 and TCM with cabling) was quite tricky.
And then at some point in time these 05-06 OPDA threads came up and I decided to go GM for the powertrain
In the Middle East we are in the lucky situation that Holden Australia is providing us with lots of LS1 V8 cars since 2000 , some of them to be considered granny limousines
like e.g. the Chevy Caprice which is a Holden Statesman WHII. It comes with full alu LS1 and 4L60E and is not overtuned and mostly used by seniors for their comfy and sovereign ride
So ... after some searching I could snatch a 2001, 45000 miles clean Caprice as donor last October for about USD 3k and drove it around to check for any hidden quirks.
Besides the typical coolant level sensor error and the A/C leaking gas everything was "smooth as butter"!
(oh ... and LM7 5.3s are same or higher price here!)
Since then I was reading here and somewhere else (pirate) every single bit of info about LS1 or LM7 swaps
Used the time to order some parts (hopefully the right ones) from Novak mainly and from Speartech (harness) and Summit for the nitty gritty small stuff.
THEN last week butchering the Caprice began:
extracted heart and kidneys
Two days ago my beloved TJ got into intensive care and is under the knife now:
degutting in steps
that much space is between (long) I6 and A/C condenser ... looks like a lot but is not too much
soon more to come
