I am building a b234 block out side of the car on a motor stand to minimize downtime of the car during the motor pull.
90.5mm Wössner Pistons 147mm Verdi Rods Race Bearings 9-5 b235 Timing Cover 9-5 b235 Oil Pan Everything else... timing chain, balancing chain, guides... are going to be replaced with new... I may even do the balance chain delete.??? I am planning on having the pistons milled to utilize the b235 head gasket ... for the time being this will be the install on the stock head until funds provide.:. Also a lot less room consuming pulling the head as I have a t5 Spg project going on in the garage. My question is which turbo should I eventually go with? The most practical seems to be the gt2876r? Stock Location, new oil and water lines with a new manifold (GS) There is also the EFR7064... with a twin it seems fancy. I don't know how that would work in the space in the front... any intel? The powerband goal is a reliable 400. A fun in the mountains and track car... |

400 crank or 400whp? Pump gas 93, E85 or both?

400wheel, e85 or pump. I am currently running a 255lb Racetronix fuel pump and have access to e85 less than a mile away. I run a somewhat 70/30 mix. I've played around with a full tank of e85 but the purity levels seem inconsistent and altitude for me is a major factor.
I should also state the current engine mods: B235 Engine Maptun Stage 3 BioPower (e85) tune (91+) 630cc Siemens Injectors 255lb Racetronix Fuel Pump PLX Gauge OBD2 Touch (AFR & EGT Sensor Modules On The Way For Remote Tuning) VDO Voltage Gauge VDO Vacuum Gauge 3" Maptun Downpipe & Flex Pipe Remus/ Saab Resonator Tip do88 Crossflow Front Mount Intercooler do88 Aluminum Charge Pipe do88 Intake Relocation do88 Heater Core Hoses ITG Open Air Filter Forge Recirculating Diverter Valve PCV 6 Stock td04hl-15t Last edited by Elyk; 05-01-2017 at 02:48 PM. |

Hi Jameson, was just thinking to text you.
Sorry to hear you are not liking the turbo... ever get it on a dyno? |

Not yet, not until I install the wideband. I've been putting time in the M, when that cools down I will devote the energy back in the Saab.

I am looking into the gt3076 as a good overall render of power. I am wondering if the stock location is a possibility with this turbo also what happens to the cobra pipe? Can it be used with a upgraded cobra or is a adapter needed? And if so what is needed to make it possible? |

The GT3076 is a good turbo, but beyond the air inlet piping, something else to consider is the steel oil and coolant lines vs flexible braided hoses.
I haven't found any flexible braided lines that don't wear out over time and use--that's a high heat area. You can insulate flex lines to extend their life, that slows things down, or swap them at some time interval before they fail, but left alone flexible tubing will get hard and crack eventually. People run adapters with flexible lines all the time, they're not like instant death or anything, but compared to the factory steel lines that don't really wear out for the life of the car, you're adding unreliability and new higher wear/failure items if you go the flex line route.

The one and major thing I can't wrap my brain around is the cobra delete unless of course the updated cobra is adaptable... I assume to some extent all that is really needed is a stock location turbo and a coupler....? Last edited by Elyk; 05-08-2017 at 01:14 PM. |
