With 10 years of experience, ScienceofSpeed has designed,
tested, and put into use some of the most impressive NSX
engines. ScienceofSpeed has designed and built engines for applications varying between the street
driven NSX to the offroad NSX powered race car.
Our naturally aspirated engine program is intended for customers
who wish to repair their existing engines and retain factory
specifications - and for customers who wish to maximize power
naturally aspirated with out the addition of superchargers or
turbochargers.
about naturally aspirated tuning:
The factory NSX engine is fairly well tuned from Honda with 270
hp / 3.0L (90 hp/L) and 290 hp (90.6 hp/L). While the gains from
naturally aspirated tuning is generally lower than forced
induction tuning - naturally aspirated engines can offer
increased power and throttle response.
Naturally aspirated gains can be achieved in four ways:
increasing induction efficiency
increasing exhaust efficiency
increasing displacement
increasing pressure & energy use in cylinder
With these
engines, ScienceofSpeed recommends a high flow induction system,
header & exhaust system.
our process: through in house research and development, we
have perfected the best formula of component materials and
design, machining and clearances, and assembly techniques. Each
engine is built in our climate controlled engine assembly room
where each component is measured and recorded as a part of our
blueprinted assembly process. In addition to the high
performance components used by ScienceofSpeed, each engine is
rebuilt using all new seals, gaskets, and bearings.
engine management requirements: ScienceofSpeed recommends
programmable engine management systems for all engines except
engines that are built to factory specifications (3.0L or 3.2L).
fuel requirements: the compression of the engines can be
modified based on the fuel used. "Premium" 91 octane (rated by
R+M/2) is recommended for engines up to 11:1 CR. For
compressions above 11:1, a higher test fuel must be used.
Compressions can be increased for applications that will allow
high test race fuel or alcohol blended fuels to be used under
all conditions.
suggested options: Each engine is assembled with a new
factory timing belt. In addition to the options available to
each stage, we also recommend considering the following items
depending on age & application:
ScienceofSpeed Lost Motion
Assembly Kit
factory water pump
ScienceofSpeed Billet Oil
Pump Gearset
factory timing belt
tensioner or ScienceofSpeed
Locking Timing Belt
Tensioner
ScienceofSpeed Oil Pan

Engine Package Details:
It is ideal for customers looking to
repair damaged or refresh worn engines. The stage 1 3.0L engine is
designed for 1991-94 M/T & A/T and 1995-2005 A/T engines. It may be used
with the factory ECU and fuel system if compression is not adjusted.
Increased compression and upgraded camshafts may be added to increase
power by approximately 30 hp (high test fuel & engine management
required).
Precision
blueprinted assembly including pistons, cylinder head studs, and new
seals, gaskets & bearings. Stage 1 includes:
components:
ScienceofSpeed piston set (pistons, rings, locks, & pins) with Xylan
skirt coating
MLS head gasket set
ARP head stud set
complete new genuine factory
cylinder head seal set, cylinder block seal set, bearing set, &
timing belt
Engine ideally suited for original 3.2L
engines & 3.0L engines interested in increased displacement and power.
Engine designed for either 3.0L or 3.2L engines (3.0L engines will
be increased in displacement to 3.2L by the increase in cylinder bore
diameter from 90 - 93mm). Increased compression and upgraded camshafts
may be added to increase power by approximately 35 hp (high test fuel &
engine management required).
Precision blueprinted assembly including pistons, cylinder head
studs, and new seals, gaskets & bearings. Stage 2 includes:
components:
ScienceofSpeed piston set (pistons, rings, locks, & pins) with Xylan
skirt coating
MLS head gasket set
ARP head stud set
nodular ductile iron dry cylinder
sleeves
complete new genuine factory
cylinder head seal set, cylinder block seal set, bearing set, &
timing belt
bushing of factory
connecting rods for floating pin
precision balancing of rotating
assembly
blueprinted assembly: set ring
gap, measure and adjust clearances, record weights, provide
specification sheet
options:
36mm intake valve (for 3.0L
cylinder heads)
ScienceofSpeed Stage 2 3.2L Naturally Aspirated Engine - NSX, all years (list: $10,410)
[enpp-2292]
$9,250.00
The ultimate naturally aspirated engine for the NSX. Compatible with either 3.0L or 3.2L engines, the
3.5L stroker engine is the ultimate engine for your high end
naturally aspirated application! Increase in displacement achieved from
enlarged bore (93mm) and increased stroke (78mm factory stroke is increased to
86mm) provided by the 4130 steel crankshaft and connecting rods.
Up to 60 hp gains using factory induction, camshafts, and 91 octane. Up
to 140 hp gains using ScienceofSpeed Individual Throttle Body Induction,
Toda Type C camshafts, and high test fuel.
