Builds V8 Swap Project Begins!

Just for reference I have a GT35R turbo on my 4.5i stock '97 engine (intercooled) running 8psi. It is fast for a cruiser and has 3" lift and 33's and some armour.

I raced my friends 2001 GMC Sierra 2wd with a 5.3 (LS1 style) 100% stock from a stop light up to about 60mph. I built boost from the line and took off first with him spinning. He got out of it and then back into it and simply walked me once he got traction. In the 5.3 one can install a used Z06 cam ($100), upgraded valve springs/keepers $100, ported TB $60, headers $500, and tuning $400 and it'll pick it up 60-80hp.

The cost to do my turbo would be around $6K-7K having a shop do it. Parts alone (ball bearing turbo $1400, turbo cast manifold $700, intercooler $250, misc. 2.5" aluminum intercooler piping $150, Tial WG $250, downpipe 3" s/s material/Vbands/bends etc $350, blowoff valve $150, clamps/silicone hoses $250+. (approx $3500 in parts) A 5.3 (ls1 style) can be purchased complete with all accessories/wiring/PCM for under $1k all day long. Then you simply have to figure out the wiring and computer trans programming in addition to an adapter plate to mate up the stock LC transmission and/or GM trans and adapter plate to the TC.


amen
there are so many 6.0l motors with autos out there too. ready to go. the wireing makes me ill just thinking about it. i love wagoneers 4.7l he's adding to his killercruiser and because he already has a crawl box and is staying yota it is cool. but GM motors and drivetrain are plentiful, powerful, and cheap
 
Awesome Awesome thread. Great to see the time and effort put into the overall appearance of install.

An A442 controller what i have been dreaming of for years i must talk to the wrong people didn,t realise there was one available. Would i be able to find out the brand of the controller. Could i also get the wiring diagrams on the 1fz fe / A442 please. My 80 is a 95 model and has the tcu as part of the eng ecu have you come across wiring diagrams like this. Thanks
regards justin
 
Here are some pics of the mechanical fan mocked up. I never knew this fan existed, it is from a LT1 Caddy Fleetwood. Ironically it is in almost the same position as the 1fz fan is. I could use the OE fan shroud with minimal trimming.

I know this is an old post...FYI. There were mechanical radiator fans on LT1 roadmasters and impalas too. Kind of wierd setup with some type what looked like an off-set drive, some had mechanical drive fans while some had electric fans...depends on the year model.

Big update!

Since I was up here in Ohio, I figured it would only be right to help Kirk with his new idea regarding the 80:

More POWA!! :grinpimp:

Get rid of the LT-1/A442A combo....took us a long time to install....took Kirk and I about 5 hours to pull out last night.... :eek:

And Kirk has decided to go with this:

:cool:

2006 LS-2/4L70/HF2AV (via Mark's adapter from Oz). Now this is going to be a pretty epic build.

So what's the big difference other than the extra Juice between the LT and LS? LT has cast iron heads and the LS has Aluminum heads or some thing of that nature? It seems much simpler swap then going for the 5.7 iForce. The 4L70 seems like the biggest upgrade. Nice!! :cheers:

#1 its cool and i wanted to do it! other than that....

100 More horsepower and 75 more lb ft of torque than lt1 (Versus stock = +188hp,125lbft torque!) LS2 Trailblazer ss engine i used has intake manifold design for even more low end torque.

A tranny that shifts firmly and takes advantage of a v8 and the torque convertor matches the engine.

ALL Aluminum. Block heads etc. my estimates are 200lbs total lighter than stock

More reliable than the LT1. Runs Cooler!
 
Subscribed!!! That's where I'm headed.

Why 4l70 and not 4l65? Is the 4l70 from a 4x2 or 4x4 or does it matter for the adapter to fit.

A 2wd tranny tailshaft is need for the adapter. I am removing the 4wd tails shaft(shorter) and replacing with the longer one.

In GM terms the 70 stands for the GVW of the vehicle(7000GVW). A 4l70 is the transmission for the high power 1500 trucks some 2500 trucks, the suburban, and escalade vehicles. So the vehicles it is in are the same or bigger than 80 series rigs. GM also makes a 4l80 and a 6l80 4 and 6 speed 8000gvw trannies. They are bigger in size and tougher, but the adapting the transfer and also the engine to tranny tuning would be more work. The Allison is the biggest of course and that is way overkill for a 80.

My goal is to take a factory engine tranny combo and bolt the 80 t/case to it. Much more simple than the LT1 to A442F swap. The LS series 6.0 engine and 4l60 tranny are literally over flowing from junkyards. I bought mine complete ready to run from a 2006 trailblazer ss AWD(aluminum block), engine tranny wiring ac ps starter computers etc for $4000 delivered. It has 3900 miles and of course looks new.

An iron block 6.0 engine and tranny from a 1/2 ton or suburban would be even cheaper.

The adapter is about $1500
 
Nice find on the combo. I've been lurking on the ls1tech.com learning about these engines. I emailed Mark's to see if the 4l80 and the 6l80 to HF2A are the same bolt patterns. Cool tranny. They said, "We are currently doing an adapter for the 6l80e to cruiser transfer and should have it finished in a couple of months. The 4l80e is a different adapter. We will have the Kits available for release at the Melbourne Australia 4wd show.

Hope this helps and if you still have an interest keep in contact or check out our website for the release in September or before."
 
Subscribed. I'm leaning towards 5.3 swap, but don't know what combo trans yet.
 
That motor looks just like an LQ4, a truck 6.0L...but could just be the intake. Great combo...you'll be super happy with it!

Having run a similar combo for a few months, I have been having some cooling issues running a stock radiator, factory fan from the motor, and a custom aluminum shroud. I will eventually be going to an aluminum radiator with electric fans. I wish I would have done this from the very start, instead of having the aluminum shroud made.

Its a LS2 with a truck intake.

The LS2 was introduced as the Corvette's new base engine for the 2005 model year. It also appeared as the standard powerplant for the 2005-2006 GTO. It produces 400 bhp (300 kW)@6000rpm and 400 lb·ft (542 N·m)@4400rpm from a slightly larger displacement of 5,967 cc (5.967 L; 364.1 cu in). It is similar to the high-performance LS6, but with improved torque throughout the rpm range. The LS2 uses the "243" casting heads used on the LS6 (although without the sodium filled valves), a smaller camshaft, and an additional 18 cubic inches. The compression of the LS2 was also raised to 10.9:1 compared to the LS1s 10.25:1 and the LS6s 10.5:1. The LS2s in the E-series HSVs are modified in Australia to produce 412 bhp (307 kW) and 412 lb·ft (559 N·m). The LS2s in the Chevrolet Trailblazer SS and the Saab 9-7X Aero are rated at 395 bhp (295 kW) (2006-2007) or 390 bhp (290 kW) (2008-2009) and 400 lb·ft (542 N·m) of torque due to a different (sometimes referred to as a "truck") intake manifold that produces more torque at lower RPMs.

Put a Ron Davis Radiator in it and cooling probs are over. My Lt1 ran warm and after switching to the Ron Davis it stayed cool year round.

Good to know. That was my concern about putting a 4l60/65 in a vehicle that dry weight is 6,200lbs. So this had me leaning toward a 4l80. But I like the gear ratios better in a 4l60. So from reading the 4l70 is just a beefed up 4l60.
