Hi guys I have recently purchased my first soarer V8 from a member of the forum, and I am in love.
I am a Supra owner and have been for the past 3-4 years and which has gone through an extreme transformation from NA - TT and now to a Single Garret Turbo (which is still in progress) hoping for 400+rwkw.
I wanted a car to drive to work and back daily and what a choice I made by getting a soarer. However its no ordinary V8 Soarer.

When was that photo taken outside edge? I think that's me in the background. Anyway nice cars. I wouldn't charge it with a w58 though. Must be fun the 1uz manual.

Welcome Terence! I know your Soarer quite well (good friends with the previous owner)
And I've seen your Supra a fair bit at JAK motor-works. I get on quite well with Danny. I'm a member of the Vic Supra club too, but I don't actively post on there
They make awesome daily drivers. As you've got the e-manage ultimate, get Cihan to do a MAF-less tune, and replace the intake piping with some 3inch from throttle body to airbox. It works wonders and really opens the 1UZ up.

Thanks James Ye I was with Cihan on Saturday tuning my Supra and mentioned my soarer to him. In the next few weeks im going to put it back on the dyno soon ;)
Ill look at the mafless tune option with 3inch piping... Sounds like a good mod.
I also wouldn't mind throwing some extractors on her but I've been reading its quite an issue with the W58 box.

They need a little modification to fit Terence. Castle Hill make 1UZ extractors that are the block hugger type, and not the long ones like the Rush extractors are. If not you may want to look into a concentric slave cylinder.
Yeah def look into the MAF-less tune. When I was running the e-manage ultimate on my V8, I had the maf-less tune on it and didn't get round to fitting the 3inch intake piping for quite some time. So it came as a shock when I finally got round to it and noticed the difference with how much easier the engine was breathing.

The Supra and Soarer are two very different cars. They may share similar characteristics and share certain parts however they both feel and drive very differently.
Having said that my cars are both different to begin with. They have different engines, transmission, suspension, brakes, etc.
It may be better to compare a 2JZ NA Supra to a 2JZ Soarer.
However they are both awesome and unique cars for their time. Toyota knew what they were doing

The IMF extractors do fit , but it takes a bit of patience and creative work to avoid the Slave. Also fitted Hi-flow cats , and made up the Custom Merge Pipe from the V8-supercar thread. Opens up the 1uz from around 4500rpm onwards.
Interested to know whether the removal of the MAF is the reason or the 3-inch pipe , is the reason you feel the 1uz breathes better James ? Always understood that the Intake & more importantly the resonator allowed the engine to breath pretty freely. I though i read it was tested extensively and found that apart from more intake noise, changing the intake actually flowed less air, by deleting the resonator chamber. Just curious

Sorry James just realized your in a vvti, so totally different intakes anyway.Pretty sure the vvti doesn't have a resonator chamber ,and has variable length intake runners, so not really apples for apples.

That's right, I have a non vvti 1UZ, and a vvti 1JZ.
On my V8 Soarer, I had an e-manage ultimate, tuned by Cihan Aday. I had 3inch metal piping from the throttle body to the airbox (BFI-ed) with the AFM delete (as the AFM is a big restriction)
Quote from Cihan, which I 100% agree with. When I had this done, and the engine got up to 4,000rpm it really bellowed.
"The 1UZ-FE + MAF-less Emanage Ultimate combination is a big winner. There are significant power gains to be made by freeing up the standard intake tract. I've measured over 1.2 psi pressure drop over the standard intake manifold at full bore on a standard engine with an exhaust system. Thats 1.2psi out of a possible ~15 psi lost to the airflow meter, intake box, throttle body and air filter. AFM removal, with a 3 inch intake pipe assemble and high flow panel reduced the pressure drop at 7000rpm to 0.6psi. The net difference was 6rwkw from the AFM removal and revised intake setup on a standard engine after the emanage had already been tuned. Tuning + AFM removal combined released in excess of 18rwkw, which translated to a legitimate %15 power increase for this engine
Another aspect of engine performance that is significantly improved is 'transient' response, the amount of time it takes for the engine to achieve full torque output. I've found that when running with the AFM disconnected, using the TPS as a load source acceleration enrichment corrections are much sharper.
With the complete ignition table corrected for, the improvement coming off the line is significant. I've measured a hefty torque difference under stall, off memory it was over %15 increase in tractive effort <2500rpm."
You know how a 1UZ feels boggy off the line? And takes awhile to get into it's powerband? AFM removal + retune fixes that
Not bad just for AFM removal + tune... Combine that with a good exhaust, and you're laughing

172kw's that a nice result , before the afm delete and revised intake, so 178kw's very nice ! what else is done to it ? 180kw's is around a mild supercharged v8.
Terence check the build date on your car , as 1994 was the year they changed to the lighter/weaker rods , so charging may be a no go. Also a w58 will take 200rwkw if treated right.

Yep, before the AFM delete (it was unplugged but still using all the factory intake piping) So about 178 - 180rwkw once replaced. Rush extractors, highflow cats, big exhaust, e-manage ultimate tune was all I'd done. Not to mention stupid religious oil changes and fresh plugs. Before Scott Vim had an e-manage installed on his Supercharged V8, I reckon they were both around the same in terms of performance? What were your thoughts Scott?

I think extractors and ecu is great for the 1uz and cheaper then charging. Mine doesn't have extractors and possibly cats too. I think your revved out a bit better then mine but I had lots of torque down low. I've got a dyno sheet somewhere before it had the ecu. Made 175kw.
Saturday, November 17, 2012 - 09:56 am, by: Paul Lemming(Grey_hound)
mine was around 162kw's with a unichip and just a BFI3 and manual conversion. Unichip has been removed since but installed IMF extractors - 4 into 1 ,hi-flows, 10inch merge pipe, and straight out to JASMA stainless twins. So exhaust side of things is done , now looking to update the intake , but wasn't sure which way to go. E-manage and revised intake might be on the cards. Have seriously been thinking individual throttle bodies and an intake plenum, V8 supercar style. hoping to just touch the 200kw level , as I'm keeping the w58.

I've blown a w58 behind a 1uz. Years ago now. I believe the n/a supras came out with a beefed up w58 that would be the go. I had a piss weak one cause the 1uz was stockish. Flooring it in 3rd gear at.1500 rpm is a big no.

another good cheap upgrade Terence is the Twin turbo Brake upgrade from the standard v8 brakes. More poke needs better brakes , and the swap is real easy and cheap. Other option is the Ls400 brakes or Supra brakes , but not as easy , and the results are no better , probably just cosmetic going to one piece caliper over the clamp style.
