I am sure this has been covered before. MY Soarer was pushing close to 430whp untill I went for a retune today I noticed the turbo seal was gone or leaking on the Dyno.
What are my options for running twins and where can I buy them from ?
I am assuming mine where already upgraded do to the fact they where running 1.5 bar boost.
I would prefer something ball bearing but I have no clue as to what flange the ct12a uses.
The other option I am looking at is the Single turbo conversion considering my car already has every department upgraded. I am just wondering where to buy or check out single turbo 1 jz manifolds I have seen some on ebay but they are prob china specials that would crack.
Also is I go single what turbo do you recomend using there are so many choices and I want something ball bearing that car push 500whp
Hi Jason.. Thats my kit for sale. On 16psi i managed to get 350rwhp.
I was takeing it easy on the engine and those turbos and could have squeezed alot more boost out of them.(They have a 360 degree thrust bearing in them to handle high boost)
They should get 400rwhp out of them i'd say at about 20psi, if you have propper engine management and a decent fuel set up. ( i only had 440cc injectors which were close to being maxed out)

What mods are you running Jason? Stockies dont push out anywhere near that at any sort of boost so they must have been aftermarket unless the dyno is off by a considerable margin.

Heres the list of mods i found on his home page for you Cihan.
:- Aftermarket Additions: Significant aftermarket engine mods: Big Greddy Intercooler, Greddy e-manage, hardpiping, 2JZ mark 4 supra hybrid turbos, Greddy caps, possibly new engine and possibly built internals (engine was pulled), Apexi Exhuast, significant engine management equipment, and more to be listed in detail at a later date. Car is very quick, and is running 21psi. Additonal mods: 18inch Rims, HIDs, Fully adjustable HKS suspension, Momo Steering wheel.

So all in all Jason, Yes it seems your car was running some sort of Hybrid Turbos that must have been built from Supra based turbos. I guess you would have to find out who did the work on it to find out what type of modifications has been done to the turbos.
Id be guessing they are steel wheeled and High Flowed. To be able to push out 21psi they seem like logical mods.
Something else id like to point out.. It has No Battery Terminal covers. I was talking to a guy the other night, whos Battery clamp actually woprked its way loose, and it vibrated over onto the positive terminal and caused a massive engine bay fire.
So to everyone, i suggest at least having a terminal cover on your positive side. Wouldnt like to hear of another fire like that one. Guy said it burned out ost of the wiring harnesses in the engine bay and lotsa plastic things.

Thanks Daniel.
Jason, if you do decide to go completely aftermarket twins, twin GT2554R's with custom or modified standard exhaust manifolds would be a responsive start. You would also need new intake piping because i doubt they would line up. These turbos are rated at 270hp each.
One step up is the gt2560R (0.64), good for at least 340rwkw with cams if properly implemented. Used as direct swap overs for rb26's.
Now if you are talking 500rwhp... Let me just openly state that you are a long way from acheiving anywhere near that if you dont know what turbo you want If you have the money id suggest you scrap what ever you have now, sell it off and start from scratch. 2JZ engine swap, gt35R (1.02A/R), 264/264 cams and worked head, apexi powerFC, completely rebuilt auto with 3400rpm stall, custom this, custom that etc. etc.
It not going to happen unless you fork out the value of the car plus the value of the car to get it working reliably
Good luck though. Check out www.t04r.com for some inspiration and insight.

Thanks for the info I will be keeping the 1jz though i would love to run the power fc but it does not work with the auto tranny . Also there is still plenty of room left with the e-manage. The reason why I do not know what turbo to use is do to the fact that there are tons on brands and different style and sizes. I am start to consider the single turbo conversion. Do to the fact that I would have to modify my twin turbo manifold to make a decent size turbo fit that has good responce. I have desided to go ball bearing the major problem I am having is finding a decent priced good quilty single turbo manifold and what size turbo would suite me best. I already know the car has all of the departments up gradded do to the fact the car was pushing over 425whp with the twins. The only problem with the car is that I am not sure what all the mods are like injector size or if it already has cams. It is currently the fastest Soarer in Canada.

Oh this is on a dynojet, oh well that explains it. We use dyno dynamics in australia which read vastly different to a dynojet, so asking for 500rwhp here isn't going to be of much help.
A better way to go about this is what 1/4 mile time do you plan on achieving? From here work out the best setup to suit your needs.

Jason as ben pointed out mate thae 2jz manifold will not fit the 1jz head Number 1and 6 exhaust ports are in a different place. you can modify the 1jz manifolds to fit the 2jz turbos BUT....... the dump pipes between them will have to be custom made and it is a very good idea to use a front exhaust housing on the back turbo. it gives you a little bit more room to make the dump pipes EG: try to fit 2 ..3" pipes and bend them away from each other when you have only 4" between the turbos it is a real head F*^$K.
