Hi, I'm Chris Pauluk and I live in Eagan Minnesota..

I'm hoping to figure out the best way to eventually ditch a 4cyl engine for some LS action into a Toyota Tacoma.. I turbocharged the stock 4 banger only to be at around what a stock 1st gen LS1 lays down..

I came to a crossroad of building the 4 or swapping to a different drivetrain.

I crunched a few numbers and it seems I'll have more bang for the buck with the Chevy power.

My abilities are a little on the limited side when it comes to fab and electrical work.

I work at an Aerospace company and do heavy brazing on pitot probe sensors and work in a machine shop degreasing and deburring machined parts.

My project is a 2002 Toyota Tacoma extended cab..

As of now I bought a starter turbo kit for it, installed all the goodies myself.
I've expanded on it with a pnp Megasquirt standalone, intercooler, 720cc injectors, Supra W58 trans, Competition Clutch Stage 4 sprung hub.
4 link kit, QA1 coilovers all around..
I welded in all the 2.5" exhaust with my Millermatic 211 MVP..
My welds are not pretty.. But it functions and I just need to practice more.. Having 220 in the garage would be nice, but for now I just have 110..

I did all the mods on the truck myself while I rented a 10x30 storage unit.
It wasn't fun, but I made it work..

Ideally I'd love a complete LS1/T56 dropout setup to have in it...
Then I can enjoy is as mostly stock til I have the fundage to add a pet snail next to it at a later time.

So where do I start? I'm as green as they come..
I can turn a wrench and read..

Here are some pictures of how it's sitting now..
It developed a random lean condition that I thought was the tb gasket leaking..
I made a smoke machine and it seemed that's where it came from.
I replaced it, no change on the wideband reading..

Anywho, thanks

If you can turbocharge an engine yourself, you're in the right place.
Even the smaller 4.8 LS with a turbo can make insane numbers on a stock long block.

I would look for the cheapest good condition engine I could find and make sure I get the accessories with it. You can get the wiring/ECU, or skip straight to a turbo build and pick up a microsquirt since you are already familiar with megasquirt. Use the stock injectors, intake manifold, throttle body, etc. You could use the stock cam, springs, valvetrain. Cut the flanges off of some stock truck exhaust manifolds and weld on V-band flanges. Fab up a hotside and throw on a $200 GT45 turbo. Very cheap/easy recipe for ~600 HP.

Was there ever an aluminum version of the 4.8?
​​​​​​​What would that come in?

JoeNova

No, there wasn't an aluminum 4.8.
A 4.8 rotating assembly will drop right into an aluminum 5.3 block though.

ChrisD.

What vehicles and year spans had the aluminum 5.3's?

There are heaps of them and depends on the model of engine, there is not just one type of each size in many cases etc, e.g. LS3 and L99 same size just L99 has VVTI and DOD and lower compression.

What kind of gas mileage are you getting when don't have the trailer hooked up? How much money do you think you have into this build?
