My Yota has the heart of a Pontiac!!!!!
 

Here's the specs.....
Engine, 97 Pontiac Grand Prix GTP 3800 Series II Supercharged, stock internals, ported blower, 1" ZZP intercooler coming soon, 72 mm ported stock throttle body, deleted factory MAF sensor port, LS1 MAF, 3.4" blower pulley, custom 1 5/8" headers dumping to a single 3" pipe with high flow cat.

ECM, Same

Wiring Harness, modified 93 4 runner Harness (Mine had an accident when a previous owner tried to "fix" the air conditioning by putting a 30 amp fuse in a 15 amp hole.) New harness is from an SR5, so now it is wired for cruise and power windows, mirrors, and door locks.

Bellhousing, 99 Dodge Dakota 2.5 5 spd, 2wd (Has the correct bell pattern and used the same trans as yota.) with a new starter notch cut out on the drivers side.

Clutch, jeep plate, camaro flywheel and pressure plate.

Trans, Stock yota with a jeep ax15 input shaft, dakota front bearing retainer and flywheel.

The rest of the running gear is stock. (For now.)

Working on the oil pan today (Enlarged and modified to clear the differential.) then finishing up the wiring.

dang you need a shop, and a new bumper :D

Leave my piece of a bumper alone dammit..... Nah, thats the next thing getting fixed after I get her running. The bumper was just something to keep people outta my radiator. I will finish it up though.... The bumper is actually a really nice start, 3/16" wall 4x4 tubing with 1/4" mounts.

interesting choice for an engine... cant blame you for creativity :)

No belt on supercharger = no boost lol


I'm sure you have one lol Sweet swap man, +1 for creativity!

Actually for the initial run I am not running a belt on the blower. Still has the stock 3.slow fuel pump. Boost-fuel pressure+heat=new pistons.

Good call my friend:rockon:

So, I have been welding for a LOOOOONG time, and I must have forgotten every rule in the book. I used a stock oil pan as a base for the one in the truck. This worked great, it fit, did not leak when fille with water, etc. then I went to bolt it on and noticed how HORRIBLY the flange was warped. Worked for an hour to no avail, it was beyond repair. Soooooo. Dug thru my scrap metal supply, found some 16 ga, 1/8" and 1/4" plate. This is the beginning of my "bulletproof" pan. 1/4" flange, 16 gauge walls, and 1/8" floor.....

The tubes are to access oil pan bolts without removing the starter.

flux core rocks!! I was actually thinking of a 3800SC swap, glad to see it being done..

I dont know what that thing is....but its no longer a toyota.

To the original poster, you need to change the thread title. You truck has the heart of a Buick not a Pontiac:hillbill:

James

I was just thinking the exact same thing. : ) But seriously, good luck with the swap. ...And I am dreading my 3.4 swap, atleast I dont have to make an oil pan. : )

wow that seems like alot more trouble than its worth

Don't know about that..... When the eng was in the car, with 3.29 gears, 15 psi (Non intercooled) curb wgt of over 3800 lbs, she ran consistent 12.5 sec 1/4 miles and got 26 mpg highway. This engine is a torque MONSTER, and the truck will be doing triple duty as toy, daily driver, and towing. The motor makes sense for all 3, good grunt for playing offroad and towing, reliable and relatively efficient for a driver. Not more or less worth it than other swaps people have done in the past.

dont get me wrong, I love the idea of a bigger/nicer engine. but when it comes right down to it, the 3.slow isnt that bad. :) but then again I have to bad of A.D.D. to finish something like that ha

to each as their own but torque is better than hp in a 4x4 thats why I got both an 02 built/blown 11.67 stang and a 86 yoda with a low gear to climb a mountain.... best of both worlds and not compermising in either. Good luck tho hope it works out

no bs tho whats the point of the blower with no belt?

Read much?

BTW, Rather have torque? The STOCK numbers on that motor were 240 hp and 280 Lb ft of TORQUE, it should be near 400 Lb ft with the smaller blower pulley, extensive tune, ported blower, and intercooler.

Wow, What a good idea!

Kiwi

I'll tell ya, that's an interesting swap there my friend...So what you have like 3-4 different vehicle parts in that thing...

So getting back on track here....I certainly hope this thread doesn't break down again like it did.

Its friday, and its sunny for the first time in weeks. Don't make me come in here again.

^^^ Hahahaha...

On furlough from the compound this weekend eh :hillbill:

:guitar:

Yep, actually going out to wheel my junk this weekend!

To the O.P. I think this is an interesting idea. I am always looking for other options and possibilities for a future swap. I am very curious about the mileage and how the power curve works for the application. I may have access to a very cheap 3.8 out of a buick. Keep the posts coming.

Had a few delays, finished the pan today, gotta install the starter tomorrow AM, then install the pan, diff, and steering linkages. (Diff and steering links had to be dropped for pan access, pan has to be dropped for starter access.) Then I have to finish the wiring, and hopefully get the interior back together tomorrow PM. Still have to plumb and bleed the clutch, and install batt cables (Have new cables, all 2 gauge welding cable.) Will add a set of external charging/jump posts below the drivers headlight at a later date. Then gotta get some fuel to the motor, do a quick systems check, top off all the fluids except cooling system, and she SHOULD be ready to fire the first time.

Do we suspect sarcasim?
 

Hey Kiwi, Most of us know you are the pioneer on the 3800II swap (those who can read, lol). I know it has been a few years for you, but for those who have the 340h transmissions, a 88'-92' Trooper bellhousing from the 2.8L will mate up, as they are the 60 degree GM bolt pattern. (GM and Isuzu was in bed together in those days). I too, have a 3.slow that just died at 180k with head gasket issues. I have looked at a lot of possible swap possibilities, including but not limited to the L36, L67, 3.4 toyota2, Mercedes 616 and 617 diesels. Decisions, decisions? Really like diesel but like the simplicity of the L series(if I am correct on bell housing), looking to have a daily driver and high mpg. I will watch to see how this most current swap is going to see the out come of that home made oil pan. Keep posting!
:bowdown:

Nashvegas Yota,
Any pics on motor mounts, headers and finished oil pan?

Sorry for the long time since posting.... Went on Vacation, then work has kept me from getting anything done. Near 100 degree days, no A/C in the shop at work, and long hours. By the time I get off work, I don't feel like doing anything. Will get some pics of the mounts as soon as I can. The oil pan does not hold as much as I would like, but it does fit. I will get some pics posted this weekend.

BTW, Kiwi, you are one of the people who inspired this build. Your NA truck is a damned sharp swap.

I barely know how to change the freeking oil in my 98 let alone swap a gm motor into one... and then build my own pan! Everyone here is a Hot Rodder at Heart! And that's what's all about

lets see some more picks nash!... i use flux core meh self, good stuff will weld through paint and all sorts of crap.. almost looks like you stick welded it? good choice on the 3800, just keep on top of those pesky intake manifold gaskets arg i hated fixing those...

So just looking for an update here how is it coming along? I would love to do this in my yota It works great in fieros why not.

Subsribed! Starting to amass parts for my 3.8 swap in a few months, nothing as ambitious as this though. Good luck and keep the posts coming.

Any updates? Very curious to see how this works out.

Sweet!

Sorry guys, not much progress, just a lot of backtracking..... Had to rebuild the headers completely, they were routed out the pass side, and even with wrap were trying to cook the bushings out of the suspension. Haven't worked on her in a while, they are killing me at work right now. Gonna start back up on her in the fall when it is not so miserably hot. She has run though. Still have a few bugs to work out too, but it will get there one of these days.

I finally have had the time and resources to fire back up on the swap. I have redone the blower for the third and hopefully last time, I got a turbo outlet elbow from a junkyard detroit series 60 and it is the perfect size. Grafted it onto the blower after cutting the cast up like a butcher on crack. Made a new flange from 3/4" aluminum plate. (Freebie thanks to my local scrap metal buyer.) Unfortunately, I have taken a bunch of pics and just realized my work comp does not have a memory card reader, so will post them tonight. I cut the last 1.5 inches off my 72 mm throttle body and grafted a mounting plate for an LT1 MAF sensor to it to shorten the intake package. Hoping to finish the headers today after I mount the blower. Will get a few more pics today as I go.

sorry guys, double post.
