Worth the upgrade to 71HTA CHRA from stock 9 turbo??
Hey everyone.. so i've been looking into getting a turbo upgrade and ive looked into the FP Red, green or even the CBRD BBK-B however those are really pricey would require fuel system upgrades i would think. So i was looking into the 71HTA CHRA because it seems like an awesome bang for the buck. Question is, is it worth the upgrade from the stock 9 turbo? My car seems to perform really well on the stock turbo. Ive done 11.5@118.7 on this stock turbo and ive surprised so many people when i tell them that im still stock turbo haha.
Anyways, here's my current mod list:
Stock block and cams (96k miles)
Stock turbo
ARP head studs
Walbro 255
FIC 1120cc
Buschur 3.5" FMIC w/ IC piping
GS 3 port EBCS
Intake, TBE, o2 dump
E85 (413whp/425wtq)
Probably forgetting a few things but thats most of it.
I was planning on running stock cams as well. Would my fuel system set up work for this turbo? I see the injectors being fine but possibly maxing out the stock wally 255.
Thanks everyone!!

I figure might as well upgrade. Already did a mid 11 pass on stock 9 turbo which was my goal lol.
I know this might be a bad question, but what whp numbers should i expect out of this turbo on stock block/cams? i was hoping for around 460-470ish and keeping my torque where it is now (425 ft/lbs)

Nvm just found some info on it. So they're a 270 duration with a 10.70 lift on the intake and a 10.20 lift on the exhaust. Sounds comparable to a S1.

It's a do it yourself project. From start to finish it took me about 4 hours. No machining required. Just take off your intake and exhaust manifold, remove the oil and coolant lines, unscrew the CHRA clamp, remove stock CHRA, swap the WGA over, bolt the 71hta in, connect the oil and coolant lines, and bolt the manifold and intake back up and you're good to go.
