So it begins...

Much more expensive than you'd think - more (reliable) power is easier with an LS swap.

The SRT kits didn't seem that bad, but I guess it depends one what you can do the LS swap for.

It's not really much cheaper, and passing emissions would be problematic.

How does the OBD check work running the dual ECUs, just uses the GM for everything on the emissions side?

The SRT kit costs as much as a used LS1 and transmission. That's just the kit. You've still got to tear down the GE engine and do some other work to make it reliable. 95% of the IS300's are auto's and general concensus is the transmission is good to 400whp at best. To get it to pass AZ emissions (CEL test) is much more work and money.

GTE swap won't pass emissions at all (no OBDII). Plus you still don't get the insta-torque of an LSx. One of the guys who was running a stock LS1 plus a 175 spray was running mid 11's on the 1/4mi. An LS1 swap is also substancially cheaper than a GTE swap. A used LS1 and T56 with all accessories can be had for $3,500. Add another $1,500 for the swap parts. GTE and Getrag is going to run you $7,000. Then you need to convert the GTE to a single turbo.

As long as the LSx is newer than the car (2001) and has all the sensors intact, it will pass without issue. They'll just read a GM motor instead of a Toyota.

you need parts 3,5,7,9,11. LH side headlight area looks like it can be useable. but better pics will be the judge of that also there is a center stay for the front that needs to be ordered as well that isnt pictured.

You mean in addition to the lock support (part 14)? Also, some of the bulbs were still good for the headlights and the igniters still work as previously mentioned. He either cut the wires for the fog lights or they got sheared clean off. Auto leveling motors for the headlights may still be good.

I want a manual IS300 + LS3, whar can I buy one? :awe:

Is that further than you were expecting me to get?

 

[phucheneh]

Why the hell would you LS swap? You can make more power with that stock-ass engine and a turbo (okay, and changes to engine controls).

Supra front brakes are a common upgrade for those. Add decent coilovers and sway bars and they handle pretty mean.

Price list to do it right? While remaining OBDII compliant - so no standalone allowed.

 

[phucheneh]

So you'd be swapping a GM V8 into your Lexus in the hopes of remaining OBD2 emissions compliant?

Eff that, sir. Eff that in its anus.

Way to dodge the question.

And actually no, it's not my Lexus.

 

[JoLLyRoGer]

I think this has to be one of the best ideas....ever... Bravo! Keep the build pics rolling in! Anxious to see how this turns out..

And you live in Mesa? I might just have to invite myself over to see this in person!.. Maybe a Friday night trip to Speedworld will be in order?...

This has already been covered, and no you can't. Not reliably. If you have data to prove me wrong, by all means do so. But I've spent a significant amount of time researching this so I'm pretty confident in this.

An LS3 with cams/bolt ons will get you to 450 whp, 470lb/ft with a power curve that will make a boosted GE cry. There's absolutely NOTHING stopping you from boosting or spraying an LS. One of the turbo LS builds was at 570whp, 590lb/ft at 7psi. Yes, 7 whole psi. A stock LS1 with a Procharger will get to roughly the same HP numbers as the SRT kit and have all of the torque. Which brings me to....

SRT Stage 3 Turbo kit. Starting at $6,749.99. Rated for 500bhp.

That does not include the $900 (plus shipping) of transmission upgrades so you don't blow it up. That puts you at $7,650. That's $7,650 to bolt on parts to an engine with 208k miles on it. $7,650 will get me a low milage LS1 AND T56 (which are rock solid at that power level) plus a good start on upgrades.

So you'd be swapping a GM V8 into your Lexus in the hopes of remaining OBD2 emissions compliant?

Eff that, sir. Eff that in its anus.

It's not a hope, it's a simple fact. As long as the LSx is the same year or newer than the factory engine and all emissions related equipment is intact, it will pass emissions as it meets or exceeds the emission standards of the original engine and will not have any CEL issues.

Yeah, we are a long way from the Speedworld point but definitely going to want to do some runs with it.

Right on man, planning on getting into an LS2 swap for my MK3 Supra soon myself!
I've learned a lot planning out this swap, let me know if you have questions!

I got your PM but apparently I can't reply until I have 25 posts. I'm aware of those other options, but right now it's too early to be debating those details as that doesn't change the overall build. Still going to need the same headers, mounts, etc. That can be debated when it gets closer to engine purchasing time.

take them out of the box and get them dirty! and i will be happy!

 

[XavierMace]

The thermometer already is. I can tell you the temperature of every device in the house giving off heat. LOL. The exhaust on my ESX box is 92 degrees.

I'm debating if I'm going to get a compressor this weekend or not. While I don't NEED one, I've wished I had one more than once already, even before starting this.

 

[exdeath]

By compressor shopping of course he means a ball bearing Garrett or two for the LS swap...

Then it's my turn to sit in the passenger seat with a goofy grin for a few hours :awe:

 

[XavierMace]

LOL. I have been looking at supercharger prices.
