So I have owned 19 cars and built each to my standards. This being the 20th car and I am only 20 you can tell I have a passion for automobiles. With that said I am the proud owner of a 1990 Toyota Pickup v6 sr5. Now I have been doing research and I honestly cannot find much support for these trucks aftermarket wise unless it is all small companies where I get parts here and there. It is a 2wd truck and with all new vehicles(to me) I have questions. I have never owned a Toyota and never worked with their technology. So first this is first, the 3.slo has to go! I have read over the OBS tech article 3 plus times on the 3.4L swap. I believe if I do a careful check list and gather up all parts needed I can have the swap done in a weekend driving everyday my 100 mile round trip to work.

With that said I cannot find ANY aftermarket support when it comes to cams, pistons, rods, valves, heads, intakes, etc.

What are the weak points for these motors? I read a build up of one gentleman and it sais he used SAS stage 2 cams. I looked those up and found nothing! I am just frustrated that I cannot find anything concrete via a google/yahoo/bing/etc search.

How much power can the 3.4L block hold? Also being a 2wd truck, is there any weak point along the drivetrain I have to worry about. I am looking for 450whp give or take depending on aftermarket support. The 3.0 is great for a work horse.

Now correct me if I am wrong but I was told overall I can get better mpg, better reliability, and overall better performance out of the 3.4L. PLEASE CORRECT ME IF I AM WRONG HERE! Is so I will buy another "toy" to do the swap in. I need it to last.

Now the 450whp goal is F/I via a turbo setup. Plan do to a underhood mount unless there is a rear mount setup I like. My ideal build would be a nice DD that I can get 25+mpg highway but go to the track and turn it all up and go. And yes I know it pays to play. That is why you always have a back up motor :p

Now out of every vehicle I owned I have never not had a/c already working. Noob question, but howdo I tell if it is r134a and if it isnt, how do I convert and is there a kit made to do it

Edit: So no one bashes my idea or wants or goals, The first motor going in will be 100% stock and I will drive it until I build a separate motor and I will use the stock motor to mock up the turbo set up.

 

Welcome to the site, please do yourself a favor and search the forums everything your asking or wondering has been gone over plenty of times So post some pics of this 20th vehicle!!!

 

Way better off building a 2JZ-GTE if you want that kind of power. Gunna neet some serious meat to put that kind of power down to the ground. Good luck and welcome to yt.

 

Why waste your time with a Toyota.

You want that kinda power get a chevy build a small or big block what ever floats your boat.

After Market support Chevy wins hands down.

If your putting out that much Horsepower the drive train will need to be all pretty much custom built for A Toyota

Stock 3.4 maintained like it should be will last a long time doing the timing belt changes as needed.

weekend swap if your that good why do you need to drive so far to work.

considering you have to merge the vehicle harness with the new engine harness .

You have lots of research to do

 

I was being modest with power goals. Did not think it was that hard to get that much out of a Toyota boosted.

And I say a weekend because with 3-4 certified ASE people working on it, well enough said. Wont take long as long as I have all the parts to start with. Start a Friday afternoon, and work through Sunday afternoon.

And I drive so far because that is where the money is at. Sometimes my hobby gets expensive.

I'll get some pictures up today. Nothing special. 100% stock 2wd haha.

I was looking at getting another chevelle, mustang, Camaro, something sporty and classic but I happened to drive this little truck and well as stated, fell in love with it.

If I was to build a 2JZ-GTE I would expect 500whp all day with turbo upgrade, injectors, intake, exhaust, head work, and spring upgrades with a decent tune. After 650-700 it needs more work. Helped my buddy build his e85 daily 1500whp supra . You know low boost 18lbs at 950whp IIRC

I would do a SBF if I did a swap in this truck with a V8. Been wanting to use Jon Kaase heads for awhile and want a 3V 351W really bad. small stroke to 383 using a coast high performance kit. mounted to a t56 using an early 4.6L bell housing. That would be a dream but I am not looking for thatmuch work. I wanted a drop and go deal.

Now The electronics part is easy, ORS makes a plug and play system for the 3.4L

 

If I did decide to do a v8 swap, Northwest Off Road has a adapter kit to mount the stock transmission. And they have engine mounts that put it in the stock mount location with no modifications.

If I went this route, is a 351W deck height going to be to high for the stock hood? How much power can the R150 handle? Any performance upgrades available for that little transmission until I have time for a t56 swap and upgrade?
