1st gen street truck 2.7 Swap

Well, I'm a high-schooler with a growing addiction to these little trucks, got a hand me down 2nd gen, hence the 2.7L Swap. But anyone know if anyone sells a 2.7 racing block? Planning on running a big turbo, with a smaller to feed it. Think Civic drag racing build. Swap an old build with 700hp, which seemed to throw that truck around on drag slicks, which scares me a bit since I want to do a slammed/flush street build. Any words of advice? I'm broke currently, and this is currently a pipe dream, but hey, we all start from somewhere.

(Picture being a stance setup I'd like, smaller rims, 16s, maybe 17s, fats in the back of course.)

 

These guys are probably in the top 5 in the country.....probably only way to get better is buy all the parts from Lc engineering and build it yourself by hand piece by piece...

3RZ Stage 1 Series Long Block (1995-2004) (lceperformance.com)

Long Block- Toyota 4Runner & Tacoma 2.7L, 3RZ Engine Long Block 3RZ-LB-9504 (yotashop.com)


And these guys have the longest warranty in the business...

Toyota 3rzf-e 2.7 L4 comp engine (powertrainproducts.net)

but probably wont warrant if its turboed or supercharged....

and have a black friday deal of free shipping....if ordered in next 36hrs...



The balance shafts in these would just rob you power....so would need the delete kit.....

 

Gotchu, thanks man. I'm broke, and this really is just a pipe dream, but thanks. Will definitely keep an eye out in the future. I wonder why these aren't as popular as Honda Motors, like the K and B series for drag racing, or just performance in general.

 

These frames and bodies are so heavy....I've never heard of anyone using them for drag racing...

Tacoma and 4 runners oem engines target were for longevity, they are anything but a powerhouse.

They do supercharge well, but most utilize that for towing/hauling or if they live the mountains or 4-wheeling...

 

The 3RZ is a very stout engine with forged internals. I doubt you need a fancy block to make power but the question you should be asking is if the 3RZ makes sense these days if you want power. I would swap something else before I worried about the limits of the 3RZ block. If the stock block won't do it go LS.

 

They are heavy? Not by modern car standards. I think my 2000 4x4 short cab is about 3300 lbs. If that.

 

3RZs are very capable of making over 1000hp with significant amounts of boost at high revs. The iron block with square rotating assy works very well with the combo of boost and rpm. Even naturally aspirated you can get 250 off-road race-reliable horsepower out of a 3RZ. The street drag scene like the 2RZ for its balance-shaft-less bottom end. You can delete the shafts on the 3RZ but there can be complications with the cam sensor trigger at high RPMs. Some fun watches below…

Well the weakest link determines the strength of any system....

Doubt many drive around at 4000rpm....which is where you get the 158hp...
and about half the time the heads have cracks developing in-between the valves at 150K...
and thats probably at an average of driving around at 100hp....

So at 1000hp......what, maybe a couple runs....

Maybe nuclear harden heads? like anti tank missiles.

Any chance Los Alamos National Laboratory makes import heads for these....

 

In all seriousness would very much like to know how long the supercharged tacos are getting out of their heads...

Who has got the oldest one with the most miles...

or is it just a flatass money pit...


Probably not a fair question for 5vz......these most likely dissipate heat slightly better.......but would still provide valuable intel...


Buying a horse may sound like a great ideal......but in reality....that's just the down payment....

 

V8, six speed, and a Ford 9" if ya wanna go fast without tossing tons of money at a 4 banger. I understand doing something for the fun of it but if you are in High School you can afford a V8 swap a lot easier than a full boogie forced induction 3RZ. But do your thing! Lord knows I blew up a lot of Datsun LS series motors with turbos in the 80's and had a hell of a time doing it. Wasn't the best idea but I had a ton of fun breaking things and learning!

 

SS valves, stiffer springs and lighter valvetrain, shim under bucket, proper compression, .010" intake and exhaust, checked often, adjusted as needed these heads will last a very long time. I think you're not getting that these motors (making very high HP) run on a completely different engine management system with careful tuning. We (and the OP) are talking about racing engines that are built holistically for racing... or to the extent of their intended use. For example, Fire Guys in the off-road race truck... they make just under 300 hp naturally aspirated. They party at 8000 RPM! This truck is raced in endurance off-road races like Baja 500. Sure, after each race its tore down but they don't throw it away. Its inspected, cleaned and reassembled just like any other race engine.

The reason they don't last on everyday 3RZ beaters is because people treat their trucks like shit. You have to check and adjust your valves. Its not hard to do. I have 240k on my motor. Original owner. Recently rebuilt the motor (LCE Stage 2) and it was in perfect shape upon tear down. Goes to show a little maintenance goes a long way. And I realize most folks here on the Gen 1 forum are trying to limp by using the cheapest solutions and marvel mystery oil remedies, but there are some of us here that appreciate the high-performance capabilities of the RZ engines.

To the OP... You have a great platform to have a bitchen looking mini-truck that can easily run 12-sec 1/4 mile with just a turbo, engine management and smart tuning. Go for it!

 

Well, I wasn't looking for a super super High HP, maybe 400-500 for some nice cruising. Recently got into street trucks, lol.

But, for my daily, my 2012, do any of you know how much boost I can run? And what it would put me at? Looking for cheaper kits, as I'm in HS

 

I probably wouldn't venture more than 15psi boost with stock compression and head bolts and engine management. Any more than that and you're going to need bigger injectors, head studs and stand-alone fuel management. Also, there's no such thing as budget boost. Forced induction costs a lot of money. Period. When half-assed you will be paying 10-fold in blown motors. That's the school of hard knox. If you can't do it right I wouldn't recommend doing it at all. There's a lot going on with turbo charging. Not just a turbo, there's a lot of odds-n-ends that goes into it and that stuff is spendy. Best to work hard and save your pennies for a proper low-boost kit that's going to run around $3k+. Goals.

 

And honestly, I don't think tacomaworld or any of the other taco forums will be very helpful, mostly old grouches wondering if their frame is salvageable or why their blinkers don't work.

Call these guys and talk to people that do this every day. 928-854-1320

 

Im also a high schooler with one of these trucks except its a supercharged 2.4. Its a blast to drive but they can only go so far and speaking from experience you will want to go with something else. They wont make as much power as you want without throwing a hefty amount of money at it.

 

Correction, its fast but you can get better performance from other platforms for the price.

 

Customtacos.com is the site for street\performance Tacoma information.

I've got a 2000 2RZ, which doesn't have balance shafts like the 3RZ and has .3 liters less of stroke, making mid 300s for Hp AND Tq on 22 lbs of boost.

You do not need any kind of aftermarket block, or crank. The cranks are forged. But I did put in eagle forged rods and CP forged pistons, LCE stage 2 cams, and I'm currently running an AEM FIC 6 for fuel control. It does "ok" at best.

If you're interested I've got a thread on my project located here:

I like turning corners at speed though, not really into straight lines for a couple seconds.
