grumps2JZ Posted July 12, 2012 Share Posted July 12, 2012 hey guys after saving my pennys for many months i have finally decided to go single!!! just wondering if anyone has had much experience in single turbing auto supra's? tried to find any relevant threads with no luck. i am aiming for 500whp (ish) as i understand that is about the maximum you can put through the auto box. any reccomendations about what kind of turbo, exhaust a/r sizes etc etc would be much appreciated thanks guys!!! was thinking about a garret t67 but thought it might be too big for such a low hp goal http://www.ebay.com/itm/Garrett-full-T67-HKS-T04R-Turbo-P-trim-T4-750HP-V-Band-/380099241555?hash=item587fae2653&item=380099241555&pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr also found a cheap T70 online but it has a .48 ex housing which seems really small to me... opinions? cheers guys Quote Link to comment Share on other sites More sharing options...
V8KILR Posted July 12, 2012 Share Posted July 12, 2012 (edited) Yes, 500rwhp (373rwkw) is really the max limit of the factory auto without modifying it. Also probably not a good idea to drag race it at that power level. It would not be any quicker at the drags then the factory twins due to more lag off the line, unless you get a high stall for it. A friend went with the Garrett GT3540R (61mm) turbo on his factory auto and it made 320 rwkw (430rwhp) at 22psi. A 67mm T04Z is capable of around 400rwkw on a stockish engine, so it would leave a bit in reserve if you ever wanted more power for a strengthened auto or manual setup. That turbo comes with whatever exhaust housing you want for it. A 0.70 divided would be best if no high stall. Check out http://www.mkiv.co.nz and email me if you need more info, as I'm in NZ too.

grumps2JZ Posted July 12, 2012 Author Share Posted July 12, 2012 cheers mate, funnily enough a mate of mine was asking me about 30 minutes ago if i had seen the "v8kilr" supra lurking around!!! and here you are!!! yes i was also thinking of the T04Z but thought since it had such a high hp rating it would be pretty useless in the lower hp range. are you in CHCH?

Jamesy Posted July 12, 2012 Share Posted July 12, 2012 The T04Z will kill a stock autobox in no time mate. GT35R is the best turbo if you plan on running a stock autobox Quote Link to comment Share on other sites More sharing options...
Kaan W Posted July 12, 2012 Share Posted July 12, 2012 I am running a garett gt35R with a .70 undivided housing on a stock auto box and it broke after 2 days of me owning the car at 579 bhp. When my builds done I will be putting in the Titan auto trans with a 3200 stall and shift kit with a couple of coolers. The stock auto box lastest this power for a couple of years I believe and many have had much longer but I like to know its reliable and wont leave you stranded. Go for a Titan if your going for that power and want to stay auto Quote Link to comment Share on other sites More sharing options...
V8KILR Posted July 12, 2012 Share Posted July 12, 2012 (edited) No, the Christchurch one is my mates "V8 KLLR" Supra. My "V8 KILR" Supra is in Auckland. It really depends on whether you want to drag race it or not?. The 0.70 should help it spool okay, but it will not be close to the factory twins on spool or launch. Justin got 20psi boost at 4100rpm with a T04Z 0.96 single entry housing to give you an idea of how quick it boosts. I would expect the 0.70 divided would get 20psi by 3500rpm.

grumps2JZ Posted July 12, 2012 Author Share Posted July 12, 2012 kaan i wasnt planning on exceeding the 500bhp limit of the auto box, probably aim for 480 to be safe.... no real plans to drag race but you never know, im sure i would be very curious to see what kind of time it would run. this BPU action just isnt satisfying me!!! haha mr v8kilr do you have any spare parts you wish to sell me? im a broke ass mofo trying to do things on a shoestring budget!!!

Jamesy Posted July 12, 2012 Share Posted July 12, 2012 The BL auto seems to be a bit stronger then the Titan one. Not sure how price compares though. Are you joking?? The BL is AWFUL compared ot the Titan trans... i melted my BL drag box within a few months. The Titan trans will run 800-900hp, no one has broken one even in the USA, yet~!

grumps2JZ Posted July 12, 2012 Author Share Posted July 12, 2012 but would also like the turbo to be large enough to support a bit more, maybe 600hp. incase i win lotto a :Pnd can afford a manual conversion sometime in the future Quote Link to comment Share on other sites More sharing options...

I cant tell you mate I just drive it. Ive got the dyno sheet if that helps. To be honest I dont even know how to explain what turbo ive got, I think the .70 is the compressor housing. Its this one - http://www.aptuning.net/Garrett_GT35R_Turbo_p/grt-tbo-006.htm As for the transmission everyone I have spoke to says the Titan is a stronger box.

V8KILR Posted July 12, 2012 Share Posted July 12, 2012 mr v8kilr do you have any spare parts you wish to sell me? im a broke ass mofo trying to do things on a shoestring budget!!! Sorry, no parts to sell at this time but I can get you a new MasterPower turbo at a very good price, which will be way cheaper then any Garrett turbo. I run a MasterPower T70 and have only good things to say about them. Also check out cast manifolds as they spool a lot better then the tube ones and are good to 800+ hp.

Perhaps everyone except the only modified OEM auto Supra in the world that does 8's (see 1320ms on Supraforums USA or his website) and he runs a BL auto. I'm running a TH400 as it is stronger then any of the upgraded autos. Only 3 gears but I was manual before so no real choice.

mellonman Posted July 12, 2012 Share Posted July 12, 2012 i have a auto runing a T67 68ar hotside ddb and makes around 530bhp at 1.3 bar , nice and low boost so less intake temp but at the cost of spool , a smaller 62mm turbo would be better suited to a auto for a 500bhp goal just at high boost Quote Link to comment Share on other sites More sharing options...

V8KILR Posted July 12, 2012 Share Posted July 12, 2012 So is it stock or BL? BL. By stock I mean originally OEM rather then a TH400 or similar. Quote Link to comment Share on other sites More sharing options...
Kaan W Posted July 12, 2012 Share Posted July 12, 2012 BL. By stock I mean originally OEM rather then a TH400 or similar. How much is the full upgrade for a TH400? Because these box's I can get for nothing or have they got some special components inside? I know its just a matter of welding a new bellhousing on right or is there more to it?

I know its just a matter of welding a new bellhousing on right or is there more to it? I bought mine already modified to take 1200+ hp. It uses a 2JZ bellhousing bolted to the trans after cutting the GM one off. Apparently cost around £3500-4000 to modify it to hold that hp. Here is a picture of it. http://mkiv.supras.org.nz/images/members/kevin_th400.jpg Edited July 12, 2012 by V8KILR (see edit history) Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted July 12, 2012 Share Posted July 12, 2012 To the OP, i think by what im reading its going to be hard for you to build a reliable auto single. People pull faces when i say to do a nice build your looking at 15k+ but it seriously dont take much adding up. Best of luck with it all. Im running 558bhp on stock autobox Quote Link to comment Share on other sites More sharing options...
grumps2JZ Posted July 12, 2012 Author Share Posted July 12, 2012 thats cool v8killr, do masterpower do anything smaller than a t70? i think thats a bit big for my goals and thankyou jamesy the first year of my supra adventure has been fantastic.... well up untill i lost my license for an "exhibition of speed" about 3 months ago ;( lol Quote Link to comment Share on other sites More sharing options...

grumps2JZ Posted July 12, 2012 Author Share Posted July 12, 2012 tubbytwo and mitchell9006 i know what youre thinking haha. but luckily i work in the automotive industry so can get parts cheaper and use my own labour to help cut build costs....

grumps2JZ Posted July 12, 2012 Author Share Posted July 12, 2012 why is everybody telling me i cant do a reliable auto box single conversion yet the people telling me this are running single's with auto boxes. mixed messages ARGHHHH haha :@ Quote Link to comment Share on other sites More sharing options...
