I kinda wanna say something to li7in6 who has 20 posts...
Mind coming down off that high horse for a second?
The 2JZ is heavier than an LSx motor cuz the block is cast iron and not aluminum like the LS.
Stating the obvious does not make what i said untrue.
And we all know why the JDM motors got less power than USDM motors due to the late '80's "Gentleman's Agreement" to not exceed 280 hp.
once again stating the obvious about something I already went over.
No shit the motor's longer; it's a STRAIGHT 6 and not a V8, dumbass.
I'm a dumbass because I KNOW strait sixes are longer/taller than a pushrod V8?
It's not that tall if both motors can fit in a 350Z, 240SX, and an RX-7.
I see you're using the word 'fit' very loosely here. Not sure about the 350z but the 2jz does not 'fit' in either the 240sx nor the RX-7(FD, 3rd gen) without moving the steering rack, creating bump steer. Even after moving the steering rack, the engine is so tall in the FD that it requires a relief to be cut, or a custom hood. this is in addition to jamming the rear two cylinders down the trans tunnel. The LS1 by comparison can be made to fit with an angled TB adapter and clearancig the oil pan, retaining steering rack placement and keeping the car bump steer free.
He can run the manual R154 tranny from the MK3 Supra and still handle 700HP for ~$400 and not have to worry about shelling out $3K for the V160. The OP probably got that motor set for $1700; much cheaper than the $4k LS1/T-56 motor set that li7in6 is talking about. With the $2300 difference, the OP can put out just as much or more power than the LS1 can by replacing the JDM parts with USDM parts (like replacing the turbo and ceramic parts), and allowing the car to breath better with a better intake, intercooler set-up, and a 3" exhaust from downpipe to muffler.
Pure speculation here. You don't know how much he got his motor for, nor do you know what tranny he is using. Actually from the looks of it, he's using the auto. You can get a LS1/4l60e for cheaper than a LS1/T56 as well.
The USDM motors got 320hp to the crank in stock form, but some have dynoed more than that. With the basic upgrades, there have been results of up to 450hp depending on condition of said motor at the time. I think the OP knows exactly what he's doing and I give him props for it. Makes me wanna get a Tacoma and do the same.
You act as tho I have no experience with supra's. I know a BPU supra (with US turbo's) can make well over 400hp and a BPU+ can see over 500hp pretty easily. I'm not arguing modified motors here as he said he was going to keep it pretty tame.
If you want to go there, the LS1 can keep up till about 500hp on a horsepower per dollar scale. Arguably even after that due to the amount of work and costs involved with making a high power 2jz. Shit for the costs of some of the manifolds, turbo's and sheet metal intakes for those motors, you can build a mean ass LS2. and the LS will make more torque and not have the lag that supra's experience with big turbo's over 600hp. Beyond 1000-1100hp, LS motors are untouchable by the 2jz, but obviously that's out of the realm of reality of this swap.
Try not to come off as a snobby asshat. Just because I have 20 posts on a ranger forum doesn't mean i have no experience with performance cars and motors...
