740 Turbo project from finland

[J4nne_]

Hello D24 forum!

-Introducting the project
Greetings from Finland! I wanted to show you my 740 d24 turbo project. Project started when i bought my volvo. It had been sitting for 3-4years without driving, i decided to take the car and start project. Interior of the car was in very bad condition, its still unfinished, doorpanels etc small stuff is missing. Well the backseats were all moulded because finnish winters are pretty snowy and the car had sitted on the snow. Backseats i could recover just by giving them good clean.
Buying condition

Stock engine

Original spoiler and paint polished


-The motor
This is the part i like the most
Engine was in good shape, it did run just like new so i decided to take it part and make it my base engine for car. This car supposed to be kinda stock but then things went out of handle. I did buy big turbocharger..
Some reason previous owner had builded this engine Na even that it should be stock turbo engine.

I tell you the specs of the engine and drop some pictures
Base engine
-Stock d24t bottom end, oil sprays etc
-Stock rods and pistons
-Ported head (mild porting only)
-stock camsaft (not stock timing for cam )
-Elring metal headgasket
-rebuilded head
Ported head+lapped valves


Turbo and intercooler
-Gt35 Turbo, ar.70 compressor, ar.86 turbine
-Cummins style manifold
-50mm external wastegate
-600x300x76mm intecooler
-740 Na intakemanifold
-2,5” intercoolerpiping
-3” exthaust
Welded manifold



3" pipe

Starting to look something, the turbo looks so big on that picture




Gearbox and diff
-m46 stock gearbox (going to die very soon, some unhealthy sounds :/ )
-Sachs sre 763 clutch with stock plate
-1041 diff with g80 locker
Sre pressureplate


Fuel system
-Prototype injection pump, builded out of three pumps.
-6000rpm pulling
-Modded governor
-12mm disturbor head
-Atm stock camplate (3.1mm lift camplate waiting for some modifications)
-modded pump internal dynamic timing system
-facet external fuelpump'
-basic turned and gringed fuelpin
-Stock injectors, new heads+more pressure

10&12mm plungers

Pump teared apart

Diy fuel pin



Car is pretty angry right now, wheelspin on third gear with normal acceleration. My goal is get 250hp mark breaked on dyno. Spools up pretty good, 3000 pressure goes 0.5bar, 4000 rpm has full 2,0 bar boost.


My future plans are build that engine even more powerful
-prototype intakemanifold
-Heavy ported head, get a grinded cam for that and more agressive valve sprins and three angel valve job.
-Raise boostlevel (valve springs..)
-Modified valves to head
-Try different exhaust manifold, differet collector desing
-Gearbox upgrade
-Compound turbo (BIG MAYBE)




Overall picture of the car



So shortly, D24 with big turbo and aggressive fuelpump Now running 2.0 bars of boost and revs up to 6500rpm.
