I have a T61 turbo I was going to use on my 2jz motor for my lexus but I'm trying to sell the Lexus SC and the engine with the twin turbo stuff and I'll keep the T61 kit that I bought. It's a T4 67mm turbo and basically what I need to know is what would I need to run the turbo and make at least 400whp. I currently have

-255lph Fuel Pump
-680cc Injectors
-3" Full Down Pipe w/o test pipe
-3" Catback exhaust
-BC 272 Cams
-Stock intake with filter
-Upper IC pipe with 50mm Tial BOV

and that's pretty much it. I have an AEM wideband and a mediocre tune with an SAFC2. After I get some more parts I'll do the ecu flash. But I'd like to make between 400-430whp with the turbo. And would my stock internals hold up or would I need to upgrade my internals? I have a forged spidergear front differential and an ACT clutch so I think I'm okay there, but I never launch the car anyway lol. I'm more of a low roll race guy anyway.

 

Maybe up the injectors a little for some added comfort and obviously youll need a mani, 02 housing, WG w/ dumptube, downpipe to join it to

 

Youll also need patience for that thing to spool up. Lol. You can hit 400 hp with a ix turbo
Everything else is okay. There are a plethora of manifolds out there, but Id probably sell that turbo. No offense, its just me

 

Yah if I can sell it and get some money out of it and just buy a 20g Evo 9 turbo then that'd be fine with me lol. I really don't want to have to change out everything on my car just for one turbo haha. All that stuff above listed could easily turn into like $1,500 worth of extra mods just to run that turbo. I'm getting a FMIC kit and external o2 dump housing soon (my friend has one on his car and it sounds AMAZING!) so I guess I can top it all off with a IX turbo and probably a tubular manifold from Megan racing or something. That should get me by for a while.

 

I'd do the 61mm. As long as you're in the right gear, lag isn't that big of a deal.

 

Hmm anyone wanna trade a relatively new evo 9 turbo for my 61mm turbo? lol

 

If I were to put an Evo 9 turbo what all would I need to make 400whp? Will what I have be fine or will I need more stuff? I'm planning on getting the Turbo XS FMIC kit, one of my friends had that on his car and it looked really nice! I am also interested in picking up an external dump o2 housing. Unless I can get a tubular manifold and throw a tial wastegate on there, then I'll just get a regular o2 housing, but I love the external dump sound. My buddy has an external dump o2 housing on his Red evo and it sounds great going down the road.

Will I NEED an aftermarket manifold. downpipe, o2 housing or any of that stuff or will it work if need be the way my car is setup now? I know it probably won't make 400whp with the few amount of parts I have but I've got a good start I think.

Once I get a 20g turbo on the car, a bigger FMIC and piping, o2 housing and probably a tubular manifold just because I like how it looks I will get an ecuflash done, but probably just tune for driveability and such with the SAFC until I have everything on for the flash. I'd rather not do a flash every week as I'm installing more and more parts. I'd rather just do it all at once when I've got my car about where I want it.
