it really doesn't get more home-made than this:
. Standard japanese-spec CG10DE engine
. SR-20 internal fuel pump
. rev-limiter removed
. Aisin (RHB35 i believe) water cooled turbocharger from daihatsu mira
. standard CG10 injectors with 5th CG10 injector drilled into throttle-body
. GE pressure switch (0-10 psi.) set to 2-3 psi. ON.
. A/F and Boost gauges.
. Subaru EJ20 turbo fuel pressure regulator.
. 3-4 degrees static timing retard
. CG13 ECU (less ignition advance)
. 2" downpipe front to rear
. 6 psi wastegate actuator
. bleed valve (achieves no more than 8psi)
. NGK heat range '7' spark plugs
. HKS ssqv blow off valve
. standard manifold cast welded to flange and ported, gussets added.
yet to be added:
. suzuki samaurai intercooler (from tmic to fmic)
. cg13 cams and buckets
photo of assembly just before install:
these are photos of the engine before it was boosted. notice the GA15 airbox due to the alternator being relocated:
the engine ran very well before boost and gained alot of low end torque because of backpressure thru the turbo manifold. it was impressive, we then fabricated the boost pipe so that we could start sorting fuel tuning. our aim was to get it to work without management or even a remap! our initial idea was that ga15 injectors would suffice but this made the car bog down and idle poorly and lean out when going into more than 2 psi. we reverted to original injectors but relocated the maf thinking that it would help meter the air accurately and the ecu would do the rest.......wrong again, it cut out due to lost air via the BOV but this time leaned out at 3-4 psi. it was at this point we decided to keep standard injectors and use the fifth. off boost the car drives normally until 2psi where the 5th injector pulses and boost comes in really hard, the A/F is slightly rich above stoich throughout boost and i am very happy with the whole thing.
so what do you guys think??
