Engine Performance
We offer a wide range of engine performance parts from internal components for rebuilds and tuning for ether NA or FI.
Please navigate trough our extensive catalog using the menu on the right hand side of this page.
Common questions:
What engine do i have? | Auto to manual conversion | How to increase power? Can you predict exact gains?
What engine do i have?
If your NSX was built between 1990 and 1996 you will have a 3.0L C30A
If you have a manual NSX built after 1997 you will have a 3.2L C32B
Please note if you have a automatic NSX you will always have a C30A engine.
This engine is not identical to the manual version, there are a number of differences resulting in lower performance.
An other common mistake is to confuse C32A with C32B, although both are C-Series engines they aren't interchangeable.
C32A are relatively low revving SOHC Non V-Tec engines these are used in Honda Legend, TL, etc.
Although design technically related the parts aren't interchangeable with exception of Oil filter and electrical components.
Fun facts on C-Series engines, NSX engines are very closely related to C27A Legend engines of the 80's and share the same design.
There are even interchangeable parts.
Early prototype NSX's even used the Legend C20AT 2.0L wing Turbo engine which constantly varied it's turbo blades being extremely advanced for it's day it minimized turbo lag.
The first V6 Honda car engine was designed in the late 70's as an F3000 Engine, Called the RA series it developed in to twin turbo F1 engines with 1500+ HP later in the 80's.
These engines sparked development for C-Series engines, C20AT 2L turbo's inspired on the F1 engine.
C32A and C35A Engines where designed after work started on the NSX, Although designed for luxury cars there induction system are more advanced.

I want to convert my automatic NSX to a manual one.
This is a rather more complex undertaking than with "regular" cars, and we generally advice clients to purchase a manual NSX.
Not only are the C30A engines different, you will also need to swap a number of electrical and interior components.
Normally we do have most parts to preform these swaps in stock used.

How should i go about increasing power?
This is a very common question and we have split up various options in to stages of tune.
| |
Naturally aspirated |
Rough Gain |
Stage 1 |
Air filter + housing, Exhaust system, ECU, Throttle body
(full exhaust system, air induction line, ECU, over bore TB) |
30-35 HP |
Stage 2 |
Camshafts, Valve springs, ECU (retuned) |
|
| Stage 3 |
Custom internals, storker kits, high compression, ITB's |
up to 300HP |

Can you predict exact gains?
NO, nobody can! each car has a number of unique factors that have direct effect on horsepower and how it performs on a dyno, you can only make a calculated guess.
To name a few of the factors:
-
Condition of engine (millage, condition)
-
Type of fluids and condition (oil, fuel, etc)
-
Environmental (temperature, humidity, altitude, barometric )
-
Dyno calibration (basically each brand of dyno will give a different figure, Specific dyno calibration factors also come in to play)
-
"package/setup" (all other modifications interact with each other in a certain way to produce a output)
