What would be better: 1. turbocharging stock SC300 engine and upgrading tranny or 2. replace with Supra engine and tranny. Looking for low 12 sec 1/4 mile and 0-60 in low 4 sec. What would be the costs with labor?

FLex,

I would think that if your engine is in decent shape and you are like most people, value conscious. Then option #1 is the way to go. For $6500 or so...you are done. Supra TT swap is probably double that or more.

You would get more HP out of turbo'n your stock engine than you would if you swapped in a supra TT engine. Plus, it is around 7.5k for a complete turbo setup for the 2jz-ge and you would probibly spend around 12k for a 2jz-gte and tranny. Not to mention you need the Supra ECU and other things. You can make around 450rwhp on pump gas and in the 500's on race gas on the sc300 engine. The supra engine will probibly turn out around 420rwhp with some tuning and uping the boost. This is on stock turbo's though....if you are looking for huge hp #' then you can always dump ANOTHER 10k and upgrade the turbo's.

 

Where are you getting your prices from you can get a motor complete for about $3500.00with the auto drive shaft and rear end $700.00 wiring $1000.00 if you are not handy with tools .
This looks like$5200.00 to me now if you get greedyyou can spend lots more, i personally am going the swap route as my car will converted to stick.

 

I think PHR charges $10k+ to do the swap.

I think the difficult is in finding the parts first. Turbo parts are alot easier to source.

Bean, is that you?

 

Nope

I dunno if I've ever seen a engine/tranny 2jz for $3500

more like $4500 or $5k... and the rear end usually runs around $700...


I'm a 'turbocharge the ge motor' fanatic remember?

 

I've seen a j spec 2jzgte for $2200 no harness and ecu, but I know of a place that makes harness' for $500 and have seen ECU's going for $350. The tranny $2000 and don't know about the other tidbits.

 

I got my engine for a good deal $1200.00 from my friend who imports engines inc trannywhich i sold back to him when i decided
to go 6sp which he has had a shift kit installed in it for hit turbo gs300. It helps when your friend imports stuff, i am waiting on my exhaust which should clear customs tommrow will take a pic it's
3"pipeing all the way through .

 

Anyway to get a "friends and family" ClubLexus deal with your importer friend for a Supra engine and tranny? I just had to ask.

 

what kind of exhaust you getting?

 

the jspec motor is pretty much inferior to the US-spec... smaller injectors... different sized turbos... and a less-wild cam profile (i think)...

not a good basis to start off of; might as well spend the same or similar money for a bigger badder US version

 

The j spec motor is not inferior has smaller inj and turbos but in my case it is not a problem as i am going t78 or t88 have both i will try the 78 first and see how i like it .So now i am selling my vpc
and e'manage with the inj and fuel harnes and the soft ware.The
the j spec is map already. my exhaust which i have been waiting onfor 3mths is still in customs should have it by tuesday.
I am hopeing to make decent power when it is finish 850cc inj and bliz 272int 272exh cams and some other litle tricks.

 

buy a toyomoto turbo kit for your car and be happy...on a stage 2 i went 11.90@115 on pump gas and good tires...you dont need the swap...and the swap needs alot of little parts that really add up fast....little crap like moving the power steering resivior...and alot of other little things....just turbo your motor and have a 400+ rwhp car that you can drive everyday...toyomoto can get you where you want for the right cash...if you have questions feel free to email me
