Hi Krazy27,
How much psi boost are you using them ?
Is it true they are spooling fast and it can be helped by the 12 psi wastegate setting?
Do you ride a stock short block engine with them ?
Don't know if it's your only experience with upgraded turbos but I have used Sylvia S14 turbos similar to Z1 GT600R BB turbos (I have built myself all mod parts) except use the huge body wastegate that requires me to clear out the passenger engine support too. I had 500HP at 18 psi boost with immediate spool-up from 4000 RPM but don't know really the open minimum psi these actuators were set.Garrett BB CHRA cartridges can't be rebuilt, only buying new ones expensive so sold mine worn out. The Garrett journal bearing CHRA can be rebuilt with available kit that is useful if your car starts to release engine bearing metal cips that will scrap your turbo journal bearings and housing bores that will need a rebuilt. The following cheap turbos doesn't offer rebuilt possibilities you better don't destroy your engine using them or you'll have to throw them to garbage I have bought a cheaper set than Godspeed one from China which specs are: Compressor: A/R 60,
Trim: 51
Wheel inducer: 42.8mm,
Wheel exducer: 60mm,
Exhaust Turbine: A/R 86,
Trim: 79 mm
Wheel Inducer: 46.2mm,
Wheel exducer: 53mm,
Wastegate psi around 8 psi (I guess) Godspeed list :
Compressor : A/R 60
Trim A/R 60
Intake side inducer 46.48
Intake side exducer 60
Exhaust A/R 63?
Trim 63?
Exhaust side exducer 47.12
Exhaust side inducer 53
Internal wastegate set at : 12 psi
Capable of 300 HP
4-Bolt Down Pipe Flange Pattern
Another one on ebay as cheap as China one sold in Ca State
Compressor:
A/R: 0.42
Trim: 40
Exducer: 59.7mm
Inducer: 37.8mm
Exhaust Turbine: A/R: 0.86
Trim: 73
Exducer: 45.47mm
Inducer: 52.90mm
8psi Internal Wastegate Setting
Capable of 250+ HP
5-Bolt Down Pipe Flange Pattern Would like to understand tose differences and capabilities on psi boost, lag time, HP output I'll probably post this question prior to make a final choice on cheap turbos
