Ls1 to Ma70 supra

[Mazda_DohC]

hi all ive been given a 1986 mk3 ma70 supra thats in pretty good nick .

i wanted to stuff a quad cam toyota v8 but have heard that the toyota powerplant is a tad wider than the ls1.

so im leaning towards the ls1 and t56 ..

ive checked the rta site and according to the formula the supra will be ok with the 5.7 motor.

what do you guys think ? I have also thaught of the 2jzgte with 6 speed but thats gonna cost more than what a ls1 6 speed package will cost.

anywhere that you can reccomend to buy good ls1 engines in sydney ?

cheers

the 2jz will be much cheaper in the end.

If your a cheap skate just match to an r154 or w58 as its the 6 speed in the package thats expensive. ebay special manifold and cheap single turbo will net decent gains cheaply.

I honestly think you will easily have a 350rwkw 2jz with a w58 installed and running for less than a 200rwkw ls1 setup

If cheaping out is the reason for going ls1, think again

[Risk10k]

Actually, the smartest thing you could do would be to use a 2jz and a t-56. A W58 box will lunch itself rather quickly..

If you put an ls1 in a mark 3 I will hunt you down and burn your car to the ground.

jeeze butthurt much?

agreed with marv why not, would be heaps of fun

[Mr Ed]

2JZ/R154/loom/ECU will be around $4k. With $2k of upgrades it will make 350rwhp.

LS1/T56/loom/ECU will be around $3k. Same sort of power out of an LS1 would cost..$4k?

Not a huge difference but the 2JZ would be alot less work. If you go 2JZ dont bother with a W58, cheapest/best option is an R154, if you wanna spend more go for a T56 or V160.

Im putting a 2JZ and T56 in mine. LS1 would still be cool, if I started from scratch again I would seriously consider it, but I already have a 2JZ/turbo/etc and I know alot more about them than those devil GM things.

Ha ha ha ... well mr Ed makes sense so I will consider it as its a unique and different conversion than anything else. 1jz 2jz has been dine to death..
I've allready had a twin turbo soarer and a vvti chaser..

First time in my life I purchased a Holden ... vy ls1 with 6speed.
and I enjoy driving it...

Then this supra pops up for a packet of chips!

The thaughts of twin turbo supra ls1 is too tempting....
I love my Toyota's but I'm nit fanatical to stick with toyota engine. The 1uz is wider than the ls1 so choice is easy to make.

Thanks for your input mr ed will keep researching but I'm leaning heavily to the LS1

[ga70tt]

i do like the sounds of this idea...

wont be the cheapest way though as ed pointed out...
i am however all for the idea to be different

and big single or twin turbo ls1 would be rather cool

space i think will end up being the limiting factor...

[TRD-RT81]

been done plenty, mate had a turbo L98 in his went very well!

[Mr Ed]

Ij?

[TRD-RT81]

yeah

A friend is doing a 5l Windsor into his mk3 atm. Why - cos he can, he's old school and knows that stuff best.

Pretty much agreed, but your prices seem a little off. $4k seems like a lot for a 2j/r154/loom and ecu. should be no more than 3k. I also think 2k of upgrades will net you more than 350rwhp.

[Mr Ed]

R154 packages are pretty expensive these days. Its half the reason I just got a T56.

Probably should ask, what is in the car at the moment?

[spiller]

Free Ma70, did well there.

Like has been said, 2JZ is the best option bang for buck, tried and tested. If you want to be different, put a rotor in it, I don't think that's been dome before (probably for good reason lol)

I sold my last r154 for $500. Guy got a good deal though and was a mate. But $1400 should still be pretty easy unless they have gone even higher? The price of the w58 is one reason I rate them. They can take a lot of punishment, more than people think.

t56 and 2j does make sense too.

[spiller]

500 is waaaaay below market value for an R154. Expect to pay a minimum of 1200, I wouldn't pay much more than 1300 for just the box and bellhousing alone though. They are the most overpriced piece of equipment out there (next to an unopened RB26) given the fact that most of them are 20+ years old and prone to first gear thrust washer failure...

are you serious best ive seen is 3.5k for an auto front cut

if you kniow where to get a 2jzgte and r154 let me know..

btw id rather have the t56 behind a 2jz as i have driven the r154 and currently own a vy ss with t56 and its a better box to drive actually I was quite surprised how good it was on road.

its pretty sad 7mge with a340 auto that is stuffed really have to rev the engine to get it to move....

im just waiting for my s14 sr20 engine and box to sell then ill have funds to buy engine for this project ..

(im just waiting for the 1st person to tell me to stuff the sr20 into it with a great big turbo)

this is so true mate you would need to address this problem before installing the gearbox to be sure !..

I was leaning to the ls1 as Ive fallen in love with the v8 rumble

[Mr Ed]

You should go 2JZ/T56....we can do a group buy on clutch/flywheel packages

seems like the easier option obviously not knowing what is required for the 2jz swap...

[Mr Ed]

A70s came with JZs and R154s from the factory, so if you get the right bits its a simple bolt in job, the only complication is the wiring but these days its been done so many times its not much of a big deal. Clutch/flywheel/etc is all available off the shelf.

T56 isnt a bolt in job. Ive been mucking about with mine on the weekend and it looks like there will be a bit of slicing in the transtunnel. Dont know the extent of it yet though, hopefully just loping off the passenger side mounting point. Clutch/flywheel needs to be modified somewhat, easiest way is using a W58 package and getting the clutch spline changed over to suit the T56 but I havent come across a W58 clutch that Im convinced is reliably strong enough for ~500rwhp.

[Mazda_DohC]

this is what it should look like
