Hey guys, I have started a small project and have been gathering some parts and research for some time now. Finally it has started coming together. The Project is about turbo charging a Nissan GA15.5DE. The block is a 1999yr GA16DE and the head is a OBDI GA15DE and I'm using the 1999yr GA16DE intake manifold with injector rail and TB.

The parts allocated for the build are: EMU: Greddy Emanage blue with 3 BAR MAP sensor, injector harness, ignition harness and USB support cable. Turbo: Garrett T28 (from skyline). BOV: Turbo Smart Vee Port. Fuel Pump: JECS (RB20DET pump). FPR: Mallory Ignition 4305m. Air filter: K&N cone filter. Turbo Manifold: Custom made (40 schedule steel). Oil lines - Braided stainless steel lines. Intercooler: FC RX7 stock IC. Injectors: 370cc side feed. Radiator: double core copper/brass. Fan: slim line turbo fan (for radiator). Spark Plugs: NGK IX (heat range 6). Muffler: 2.5" in (free flow).

The compression in the combustion chamber was dropped and the exhaust ports were ported for better flow.

The engine is going in to a Nissan Sunny 4WD B14. Pictures will be uploaded in time to come.

UPDATE

Nice project boss! You might suffer a bit with power because its 4WD but she will be fun! Is the car going to be manual or automatic?

Auto for the while, manual soon after Mr. Green

^^ could be a thicker head gasket or pistons were changed I guess..

AFAIK there are no thicker head gaskets for the GA 15, unfortunately.
The only low compression pistons that you can use that have the right length are from the E15 ET and the block needs to be bored some. The head when you look at it has little you can do either. Mind your boost and fuel my 15 graveyard full at teh moment.

Nice project.

Turbo looks a little big for the GA15 though....with low RON gas and all.
