2G Upgrade Path


The following is a suggested upgrade path as put out by Mike at Road/Race Engineering.

PLEASE NOTE that all prices are current as of 10/20/99, but they can change at any moment, so do not take them as gospel. They are a general guide only, to give you an idea of roughly how much the mods will cost.


This is the upgrade path that we recommend for the second generation Eclipse/Talon. Here is the current list and prices. There is a reason that we are using the parts listed here - they work. They have not been chosen because they are in style or fresh, just proven. If you build an "all GReddy" or "all HKS" Eclipse, or if you want a Blitz BOV just because everyone else has a GReddy, your performance will suffer.

Next you need a turbo that can actually make some boost, but most people will spend some money on other stuff first. A turbo is more money but will make more of a difference dollar for dollar. The following is a list of things you don't really need without a turbo, but if you get them you will be laying the ground work for the turbo.

OK, now you really need a turbo. With the turbos up to the the 18-G, you can keep the boost down and need only an upgraded fuel pump. To run over 15-16 psi boost on pump gas safely, you will need more fuel. Even at 13-14 psi, these turbos will all blow away the T-"Too Small" Garrett at 16 psi.

To take full advantage of all the air flow that you now have, you need more fuel and the ability to control it.

Fuel Apexi Super AFC  
This allows you to modify the signal from the MAS (air flow meter) 
to the ECU to help trick the ECU so that you can lean things out to 
make up for larger fuel injectors. The AFC will also help compensate 
for removed honeycombs to make for a smooth idle. 

With the stock injectors (450cc/min) running out of capacity at 
15-16 psi boost on pump (92) gas, you need to swap them out with larger 
injectors. 550cc/min work well on pump gas up to arround 16-17 psi 
on pump gas and with race gas up to 22 psi. With the larger 660cc 
and 720cc injectors, you can run more like 19-20 psi on the street and 
as much as your motor can take on race gas.

With proper tuning, race gas, and driving like a man possessed, the above parts are good for 11.96@115 mph with a 16G turbo and 11.8@118 on a GReddy 18G so far (proven at the track). Both cars were full weight and with stock 2G intake manifolds and stock 2G cylinder heads.

Prices good as of 10/20/99. Prices are subject to change without notice. Install prices are for local customers only. Prices may vary if your car is a star in the Dope Show. $100 charge for every time your alarm goes off unless we can cut the wires and stomp on it ;-)
No honda owners were actually humiliated during the writing of this price list.
