Trying to decide which turbo setup to go on my GTR, but dont know an awful lot about turbos or how each perform to each other as ive always had factory ones in my cars.

Anyway the 2 im deciding are HKS gt2530's or garret GT2540R's

heres the specs of the second:

#####################

Dual Ball Bearing GT25/40-R Turbo assembly with specified ar. T25 style inlet flange with 5 bolt style exit. Large 60- 1 style compressor housing with 4.00" inlet and 2.50" outlet.

Very Good response turbo for 4-6 Cyl applications.

This turbo has a flow capacity of about 450HP.

Turbine

-Wheel: 53mm w/ 62 trim

-Housing: .64 ar, .86 ar

-Maps: Not Available

Compressor

-Wheel: 60mm w/ 60 trim

-Housing: .70 ar

#####################

I assume alot of you know the specs of the hks 2530's so how do they compare and which would be better to go with?

hks specs are here: http://www.hksusa.com/categories/more.asp?id=1092

If you do a search, there are many comments on both turbos, well not alot specifically on GT2540, but a few on HKS 2530 and HKS 2540.

Summary, 2540 good for drag, not much else, 2530 killer on the street or track.

    • Why are you so adamant on going M12? Why not follow Brad (GTSBoy) suggestion. You're talking moving from a 1/8" size, to a 1/2" effectively. 4 times bigger. Why skip the commonly available sizes in between? The bigger you go, the more likely you are to strip the threads out at a later date, as guaranteed, someone will put a huge spanner on the M12 and really tighten it up, and you're only in thin wall, so not a lot of threads to engage!
    • Hi. Yeah thanks. Car is already at tuners and it staying there to resolve "many" issues they do not like. So it is in a good hands. Getting a good tune on that Nistune ECU too so the car would be good. Just needs a little tune up and love.
    • Probably gonna remove manifold and turbo. I’m not sure if I can get M12 x 1.5 air tight. Could use high temp Loctite 246 or something similar, but I don’t know. Maybe it’s just best to remove everything again and weld an 1/8NPT on there instead.
    • Yeah, saw the ratios, not impressed. Would like the punch I have in the first gears now. With those ratios it won't be the same.  Also want the h pattern gearing, or at least a quiet gear set that don't need to come apart for service each year. Looks like the only "reasonable" way Is a 8hp70 transmission, but where is the fun in that🤷‍♂️
