im in need of new injectors soon, but i dont have the money to buy some big ones yet, so how well do the Se's 620 injectors work? do they pop on without any mods? i couldnt find much info in my search, just some mentionings.... any help is appreciated.

 

anyone?

 

i think there 680cc

 

A lot of places (Mazdatrix/RacingBeat?) recommend to use the 680's in the secondary positions if the exaust has been upgraded on a turbo car. Sounds reasonable to me.

 

exhaust has definately been upgraded.... but one of the injectors is faulty. im just thinking about getting some SE injectors to hold me over. but then wont i have to have my car re-tuned after intsallation? (microtech.....)

 

They are low impedance injectors, so it will only be drop-in if you have an 86 or early 87 car. Yes they will probably need adjusting, but if you already have an upgraded exhaust they would probably be OK without tuning them. If you wanted you could get a S-AFC or similar to adjust them.

 

GSL-SE injectors are 680cc injectors. Depending on where you have them tested and cleaned you may see flow rates up around 720ish. I have four that tested 704cc, 712cc, 724cc and last but not least 728cc. I recommend WitchHunter to service your injectors. They use a test fluid that is very, VERY close to gasoline in specific gravity, viscosity etc. Most other shops use Heptane which is a less costly fluid but will flow around 5% more than gas under the same temps, pressures and so on.
Check out www.witchhunter.com Gordon is a really cool guy and won't screw you over. I think I have several pairs of 680cc if you are interested in a couple PM me and we'll work something out.
