Hi I'm about to go and buy a new turbo and was going to get the bw 83-75 s360. Is this too big for a stock block/cam 1jz.my friend with a 2jz is swearing I will regret it because I want to see boost asap with minimal lag. Keeping in kind I'm looking for 450 whp. Any people with this turbo on a 1jz please chime in. Thanks

 

That's the turbo i would put on 1jz for 450 whp goal!! It will be perfect for your application.

Go for it! Are you auto or manual?

 

5 speed Manual with 3.91 LSD diff. The t4divided .91 ar is what i want to go with. I'm afraid of having too much turbo lag or no response....I've read great things but mostly people with 2jz.

 

I think that would be perfect for your goal, even .91. I think you should add stage 2 BC cams and you will really be happy. JMO.

 

Thanks for the replys... Will be doing cams in the near future but may keep it stock for this season...will the s360 boost come on too late? Would I be better off going with the s256 or s257 which has a t4 divided 1.22ar...which seems quite big...anyone with these turbos on a 1jz please give me your thoughts thanks

 

I have that turbo with a .91 divided, and it is pretty laggy. I see full boost after 4k for sure. To be fair, I am on stock exhaust which I'm sure is not helping spool. I don't regret the turbo choice, I just know to keep it in the revs and not expect off idle boost. If 450 is your honest and true goal, I would go with a smaller turbo.

 

Well I know more power in the future along with many mods will come...however rite now at this point...spending under 700$ on a new turbo I want to buy something that is going to suit my needs now...if need be I will upgrade the turbo when I decide to upgrade the motor...hopefully not too soon lol I will be very happy with 450whp but wanted something I don't have to wait to4-5000 to be at full boost.

 

Adam- Dag that's laggy..Do you know exactly what rpm I am trying to do some comparison! And i know going with a .88 ar won't help either imo. What are you mods if you don't mind me asking?

Op then the S267 will be ideal for you setup, i you want something to will hit quick.

 

What about a S366?

I was recommended a S366 for a 500-550whp goal on stock internals with a auto tranny.

I'll be the first to admit that while I'm piecing this together myself, I'm trying to do the research so I only have to buy once.

 

When I bought my S366, I had no clue exactly the specs I needed for my setup. This was first setup and motor swapped turbo car. After my findings on here and talking to several people on here, the S366 was the way to go with my supporting mods. I honestly think it would be too big for stock internals for your power goals and stock injectors. JMO. Mine starts to spool at 3200 or at least you can hear it, but really comes on around 4200 or so. Pulls straight through the redline but I think the Soarer R154 gearing helps with this also.

 

Well I have the resistor pack and 550cc that I'll be running with an afpr...still stuck on ecu and turbo choice...starting to go a bit crazy now...knowing I was going to be doing a 3.0l bottom sometime (not this year) was making my choice 100% s360. But since I really want to enjoy my car now, And want as much response and as little lag as possible I want something a bit smaller but in the same line...so something in the s256 range is my best bet? With that huge t4 divided 1.22 ar

 

I wouldn't get a 1.22 ar, .88 will do just fine.

 

Interesting. That's my problem, I have no clue what specs I'll need for a moderate single turbo set up.

There a few supporting mods I already have in terms of 550cc injectors and 255lph fuel pump.

 

Spend a few more $'s and get a 400 series walbro if E is prominent get the 485 series.
jmo.

 

My mods are pretty much nothing lol. Stock fuel, even fuel pump. Stock ecu, 12 psi. The only things aftermarket are the turbo and front mount. I run a tr8 treadstone. I think the stock exhaust is REALLY hurting my spool. It's 2 1/4" crush bent, and is really more like 2". Plus it has a cat, a resonator, and a muffler. It's super restricitive. With that said, I did manage to make 337whp through the stock exhaust at 12 psi once it finally spooled
