Need turbo recommendation for 4G63/4G64 head/block

[dsatchell]

I'm building a 4g63 head and 4g64 block to go into my Starion and I'm trying to decide what size turbo (and exhaust manifold) to get. I will be running a Magnus Street SMIM and Kelford 272 cams with adjustable cam gears for the head. The block will be a stock crank, forged rods, and probably Wiseco pistons but mainly the bottom end will all be stock dimensions so 2.4 liters (not stroked).

I am shooting for ~450hp but this will be a daily/weekend driver so I want a turbo that will have fairly good low end response but not choke on the top end. I know that I will have an advantage in that the block is 2.4 vs 2.0 so I will have more to get the turbo spooling. I would prefer to get a twin scroll but that will depend on the total price of the exhaust manifold and turbo.

So what I need from you are manifold/turbo recommendations. What I would really like to know is which manifold, a budget turbo, and then a upgrade turbo. The more recommendations the better so that I can have some items to research.

Thankx, David.

T3 60 trim could get the job done.

hx-35 should do it with a little bit to spare

Twin scroll hx35 could also be a good option

Yeah, that would be even more bad a$$ twin scrolled. The hx35 is so cheap you would be able to justify the cost of a twin scroll.

I definitely am going with the twin-scroll and either a HX35 or HX40. I've also modified my HP range to 450-650 since they are so much more affordable. I would prefer the HX40. What can be done to make it spool faster? I want to get the boost to come in as early as possible since I'm not planning on revving over 7500.

Get the superhx40 with a billet wheel. "The non-billet wheel spools as fast as the 8blade hx40 in the bolton bep housing and has done 653whp at 40psi" "20+ psi by 4100rpms with 272s."

With the billet, 2.4l, and twinscroll your spool time should drop considerably.

Edit: Realized i posted the wrong link, hah

You could do a twin scroll HX40 in its T4 divided housing and have a monster setup that could easily get you into the 600 range. A stroker is an option too but not needed.
