need some oppinions

[masakari]

ok, i have the 95 ecu..and my tax return is filed...so before i send my ecu off i have some important decisions to make.

I am currently running denso 650 injectors...now when i send the ecu to dsmlink they reprogram it to operate stock with whatever injectors i specify...targer HP for my car is going to be 450-475...do you feel 650 injectors will be enough for this, or should i upgrade to something bigger....now is the time to do it, cause they only flash it for baseline once, after that it costs cash to have it modified

The following is guide for selecting fuel injectors corresponding to horsepower and stock fuel pressure (40psi at the fuel rail). The sizes were estimated using 90% duty cycle of the injector. The sizing of the injector is heavily dependant upon the air/fuel level the engine is tuned at (ex. 12:1 air/fuel will take more cc's than 12.5:1 air/fuel) :

310cc 200~220whp
370cc 220~280whp
440cc 280~330whp
550cc 330whp~380whp
660cc 380whp~425whp
720cc 425whp~475whp
880cc 475whp~525whp
980cc 525whp~600whp

this should help out 8)

Always helps to over shoot what you are planning on doing...

I went with 720cc injectors....

I personally think anything over 75% duty cycle for extended periods of time is unsafe, but thats my car. 8)

[narfdanarf]

I thought 80% was the recommended duty cycle

[Feedman]

I thought 80% was the recommended duty cycle

Yea...several people use 75%-80% as a good point of reference.

Again, I wouldn't exceed that...you are running a chance of damaging your injectors or worse, running to lean and lowing your engine.... 8)

what would a good set of 720 cc injectors cost for my car?

what would a good set of 720 cc injectors cost for my car?

$300 + dollars.

Depends on the brand...your injector clips should plug right in...

I think for your car you will need Peak & hold injectors.

Good luck.... 8)
