How much HP can i make with these mods....
Its been a long time so hello again everyone.
I have just finished a 3 year long full restoration of my 88 760 B230ET and i have added some modifications along the way, these are as follows... 60mm Do88 intercooler Billet ZRP Crankshaft (28KG) Original 18KG Forged H beam Rods (Maxpeeding unfortunately) ARP Head Studs and ARP crank cap Studs Metal Crankshaft oil Scraper Ported and Polished inlet and exhaust ports 3-inch Turbo Exit with high flow waste-gate (Cosworth housing i think) 3-inch downpipe into a 2.5 inch high flow stainless exhaust (still has 3 mufflers) Chipped Motronic Ecu (Boost cut off delete) Manual boost controller (set to 16psi) 52 A/R turbo inlet housing (still 50 Trim compressor) AR Gauge ECU Fuel quantity switch set to +7.5% extra fuel Standard.. Headgasket injectors Pistons A Cam shaft ZF auto transmission (yeah risky) so with that being the case How much power could i potentially make with the stock injectors and T3 50 Trim turbo ? |

Hmmmm yeah i thought so, That's slightly disappointing. I was thinking the possibility of larger injectors seeing as it is still running stock green tops.

Is it 2.3 or stroked to 2.5L? Stock crank is decent to at least 500hp..?

Seemed you have increased the strength and not the power. You need air flow for power. A later block and crank is apparently good for 1000bhp. The main difficulty with the red block is the small head and limited air flow, you really need a custom head.
Fir now you need big boost, charge cooling and more fuel, probably a stand alone ECU and cam timing. |

When I read ported and polished that is always a worry as all good head places know that polishing ports is a bad thing and would explain that a fine ground finish is best.
Power wise is going to depend on how much boost you throw at it but 200-250 BHP would be possible. Slightly bigger injectors would be advisable. Cam are you still running the original A profile cam? |
