    Very interested. I looked on here (not too Thoroughly) but didn't find anything.

    My mind wants to do an LS1 swap but only if it can be done and keep complete functionality.

    It would depend on what you consider "complete functionality" to be and what else you want to swap into the truck. The great thing about the Toyota Pickup is its popularity and that most or all of the research has been done. Usually an aftermarket company has stepped up to make life easier for whatever you want to do to them. Through either adapters to run the Toyota components or adaptation to run the donor engine/car components, you'll be able to keep your power steering, A/C, Brakes (although I would suggest a serious upgrade) as well as even using your stock gauges and heater.
    In the case of a V-8 swap like the 5.0 or LS1, the main thing I would be worried about is the gearing of the diff and trans. Its proven that the rear diff and even the trans on out trucks are strong enough to take sane driving with a v-8 swap. However, you may not be happy with the results given the gear ratio's used to accommodate the stock 4 banger these trucks came with. You could get excellent low end power, fast take offs ect. but at highway speeds you may end up running high rpm's and killing your gas mileage. Not to mention having a almost useless 1st gear as the ratio would be too high to be useful. Everything wouldn't be "in tune" with each other, which is one of the things I really love about the truck in stock form.
    To help remedy this, I'm going to do a complete swap:
    v-8 engine, T-5 trans and an 8.8 rear. Basically, it'll be making it (drivetrain-wise) a 90's Mustang. And although I don't think the mustang was as "in sync" with all its components as the Toyota, it'll get it closer than trying to mish-match components together. That's my theory anyway. I'm sure there are lots of people who will disagree with me and they may be right.
    Hope this helps.

    Yes...A/C, power steering, DEFINITELY brakes. My plan (on paper) would be an LS1, 6 speed trans, narrowed Ford out back, quality static suspension, wide wheels (tucked-no rub, no sucked in, no poke, no extreme camber). It'd be geared a bit higher since the extra torque could and would move the light weight truck off the line much easier. Hell, I may not even bother with headers or performance exhaust since the more power you'd attempt to put to the ground on a RCSB 90's Toyota would only cause (more) traction issues. I've been trying to figure out what you could put out back over the rear axle to aid with traction...possible a centered gas tank and the battery. Other than that, I just wnat to keep it a clean and simple build. Ya know...other than THAT! Hahaha

    I plan a V8 swap in mine this summer. Going to use a dodge 318. They're potent and hard to kill. I've been building them for 20 years and know their potential. Aside from minor build specifics, I plan to run a W5* trans. If/when I grenade it i will upgrade to an R15* trans from the 6 cylinder cars/trucks. Still torn on the rear end. For now keep the stock 8" and swap to a 4 speed pumpkin. They are typically where you find the 3.08-3.55 gearing. The trans gearing isn't perfectly spaced but a its got a nicely spaced 3/4/5 for cruising. The 2/3 shift is my biggest complaint. The W58 has a taller 5th but I'm not too concerned since they are typically a different length than the others and I don't wanna mess with the driveline while I have a 4 banger. As for how to mount a Toyota trans to a dodge small block, well they built the parts for you. The 3.9l V6 from 87-91 had a bell housing, flywheel, pressure plate, ect that will work with the Toyota clutch disc, input shaft, and trans. Dodge used a crappy knock off of the W series trans. They later copied the R series trans for 92-2000. So find a junkyard Dakota and get the V6 bell housings. Either style is worth having an then go grab a Toyota trans. You will need a bushing machined to hole a Toyota pilot bearing in the larger dodge crank hole. I don't think the input shaft needs to be trimmed but some could be made with a spacer at the trans to bell mount. Hope this late night babble helps somebody.

    If you had your heart set on a stock type 8" rear end and think you'll break it, get the 4 pinion bearing style from a supra. Gotta guy the parts out of the IRS housing and into your pumpkin. Some say its worth it. I would also use the brakes from the rear spindle. Gotta move 1 of the 4 backing plate holes over 20* or so. Lotta info online for front upgrades but that rear mk3 supra setup is one I don't see talked about much so I like to tell everyone about it.

    The 4 spider diff is also found in turbo 4 cylinder and all V6 yota applications. The diff is slightly stronger but its big strength gain is in the extra thickness of the 3rd member and the extra ribbing of the case. What kills gears is the pinion deflecting away from the ring gear due to the 4 cylinder case flexing.

    This exactly wat I was looking for.
    In my Sonoma (before I sold it) I was considering an LS1. But I've always been a ford guy so a 5.0 swap into this would be awesome.
    THANKS!!!!

    Any V8 will make a fun street terror out of a Toyota. It comes down to brand preference, and to an extent, the transmission planned.
