Search has been returning a blank page for me.

I'm your Huckleberry , although it is not an LS1 it is a Gen 3.

Here is an LS6 swap:

Won't a ls1 swap cost about the same as a 2jz-gte swap? If it is, why go with the ls1?

I guess I'm set in my ways . BTW, the LM7 cost $400, the most expensive single item was the TKO600 tranny. If you wanted to be really frugal you could put the Supra Turbo model R154 in there, or he might already have one if his car is a turbo.

Simplicity, inexpensive easy power upgrades, and ease of maintenance favor the LSx motor for me, this could be completely different for someone w/ no LSx experience (although the Supra was my third Chevy V8 swap into a Japanese car, it was my first with an LSx, and from what I learned I will use the LSx for any future swaps).

Also, these cars are heavier than one would think & the extra TQ of the V8 is helpful in that respect.

Simple. More potential, less weight, and cheaper to build.

The 2jz is not all its cracked up to be. There are plenty of other motors that perform just as well or even better.

For the most part... not true.
More potential? No. Does the LS1 have the potential of pushing 1XXX hp on stock internals like the Supra does?... No.
Less weight? No. Inline 6 compared to a large V8
Cheaper to build? Depends. Normal slap on this and that, yes. The LS1 is cheaper because the parts are so available. And going single in a Supra is a pretty penny. I guess about the same (maybe a little more) than putting a large turbo setup on a LS1. But then while doing so, the LS1 MUST build internals, as well as all other supporting mods. Where the Supra does not NEED to do, in order to be above the LS1's potential.
It's late so I'm sure I'm forgetting some things.
Also I own both a MKIV turbo, and 98 Camaro Z28. So please no flamming as I am not partial to either side. Well **** that isn't true... I am VERY partial to BOTH sides.

Getting back to thread, I would say it all depends on what you can afford, and what your power goals are. Under 500 LS1, over-2JZ GTE with single swap.

Complete 2jzgte motor without tranny is about 594 lbs

Complete, Wet, no trans,crate ls1 from GM is 458 lbs

ls1 is 136 lbs lighter


i agree with GTO

If your weights are correct the whole LS1/T56 combo is the same weight as the 2jzgte motor w/o tranny. My LS1/T56 combo was 596 lbs when I put it on the scales.

THE_SUPRA

this is old news into mkIIIs

superlsx

well i work at one the most known speed shops in the usa. we dont have anything for a supra motor. so thus everything would be at normal cost. ls1 on the other hand we have everything. so i get a better deal. and i know ls1. so puting is a 2jz would not be cost effecient for me. besides having a v8 supra. just sound sick...and yes my car has a single turbo. but i dont know much about. just has a awful crank chatter. bought it like that for 750 bucks..

Sent you a semi-detailed email about my swap. Glad to help out where I can, but the car is in my new garage hundreds of miles away.

That thread deals with the MKIV Supra, same type of situation between the 2nd and 3rd gen RX7s, similar but not the same. superlsx is looking to perform a swap into a MKIII.

Depends on your goals. Does the supra have the ability to run 9's on stock internals? (or 12's, for that matter ) And a forged internal LS1 > Supra



And again we return to what goals you have. Sure, a supra will make more power for less (even though they are about the most overpriced cars on the market) but ET is another story

superlsx

its not always about et. i personaly think that with a ls1 supra you will have a better power to weight ratio. but i am still looking at both sides of the world. but i have a lot of ls1 support behind me and the resorces since i was once an cadillac tech and my specialty was cts-v. so show what the 2j has to offer. im all open for opinions.
