Kinja'd!!!

A buddy of mine installed an aftermarket launch control kit on his turbocharged SC300. It did not end well. He just got the head off and sent me this. Amazingly it still has compression in 5 of 6 cylinders. He’s cutting his losses and swapping in a GTE long block that he’s already tracked down for sale. If (probably more like when) that blows up it will be LS Swap time.

Isn’t the GTE the one that can take like 500hp on the stock bottom end?

How bad of an idea is it to throw an aftermarket turbo on a 2JZ-GE? Asking for a friend.

Just tell your buddy to swap in the LS make more power for cheaper than he ever could have dreamed of with shitty I6

A $350 5.3 LS can take 1000hp on the stock bottom end. All these race motors just sitting in pickup trucks in junkyards everywhere and geniuses are still trying to fuck with other things...

For that kind of cash you could buy an LS motor and a turbo. Sure it would take some fab work, but you’d make a lot more power

Good point. This one does (or did) have forged pistons and stronger rings installed. He was actually able to limp it like around like this for a week. That wouldn’t have been possible on a stock bottom end.

Yes. This one is a GE that had custom internals and had been running fine at 400+ for a while now until the launch control fiasco.

Honestly this one had been running pretty well for a while. Plenty of 2JZ-GE’s are running turbos. The trick is to get it professionally tuned and realize your limits. Once you get above 300 hp you’re going to have to start changing internals which means serious cash and time.

It’s probably better to just start with a GTE, honestly.

Yep the one on the end has a chunk missing. There are also a lot of gauges. The scary thing is he can’t figure out where the metal went. Probably out the exhaust, but he took apart the turbo and the turbine seems fine.

As long as you don’t try to go crazy on power, it probably would be fine. There are a couple of local daily driven turbo GE’s.

Right now it’s become an issue of time more than anything else. He’s not wedded to Toyota parts (heck he swapped a Nissan transmission into it already) but he’s got some even it needs to get to in a couple weeks and the GTE should pretty much drop in. I imagine this thing will get an LS swap at some point. So much work has been done on the suspension of this car and the manual swap that I don’t think he’s going to be getting rid of it anytime soon.

You can mate an LS motor to a Nissan trans. They make an adapter for that.

It’s not about appreciating a “good” motor, if the purpose is going fast, and you don’t already have a coyote motor in the car, swap an LS in and turbo it.

Any motor given the same budget will fail to make as much power as an LS build. These aren’t wild ass theories I’m coming up with, they are facts. The 2JZ isn’t the world beater it once was. There’s quite a few better, cheaper options now.

You’re right, it’s not all about power, but when a built engine gets its shit kicked by a $350 200k junkyard motor with an EBay turbo it really makes you reevaluate your decisions.

Well Op already said the owner had a Nissan trans, which could theoretically handle an LS motor. I mean sure you’d have to do a little fabrication, but you’d probably still make more power for less. Plus the owner has already expressed openness to an LS swap, my point is just jump right to the conclusion, because the interim step is probably just a waste of time and resources.

If everyone just swapped an LS into their builds because they’re better on paper the car world would be a very boring place. Not everyone wants a simple V8 that billie-joe could build in his backyard.

If you could get the oil pan off. Drop it, remove the offending crank and install a new piston and rings. Hone in place, and assuming the valves are still straight it might just run....

Ps, check the intake manifold and head ports for the chunk, often that’s where they end up.

Yeah I’m not sure what his ultimate plan is for this. The valves looked OK but probably need new guides. You’re right that it does look very rebuildable but short term he’s just going for a used GTE long block because there is one nearby.

Yep, the dangers of distracted posting. I meant to say rod instead of crank..

It’s amazing how junk can go through engines and you throw new pistons at them and they are fine. Granted, other pistons could be hurt too. As such, changing a piston is more of a hail mary play, though if you can drop the pan a lot less work than changing the complete engine.

What really gets to be the hassle is if a part tags a valve. First, you need head work and if the valve stem is bent, almost always the guide cracks and breaks. I figure the piece of piston having melted is somewhat soft. The guide is carbide and is not.....

I cant find a stock bottom end 2JZ in the 8's.

I’m not saying for a PRO-MOD an LS motor is the best in the world, Id argue its actually a mod motor. But for a street/strip car on the cheap, its this or Coyote. Everything else is a waste of time, money, and effort.

Agreed. You can’t beat an LS motor for cheap speed. People have made tons of power with a completely stock 4.8 and 5.3. Even the aluminum 5.3's.

I sold a C5Z a few months ago so I’m pretty aware of LS potential.
