i will be goign with 450 cc injectors on a turbo LS
power output will be close to 200 at wheels, do i have to upgrade the pump
to keep that 40 or so psi at the rail, or will the stock pump keep up?

 

Check my sig, stock pump but it leaned out a lot at the topend. Not sure if its because of the pump or the fact thats its not tuned.

 

For what you want with the set up id say the stock will hold. But why even question the stock one . You can pick up a 255lph walbro for around 100 bucks. That would be a $100.00 well spent. Dont take any short cuts at all when it comes to fuel!!

 

I can understand where he is coming from though. The tank has to be dropped to replace it, major pain in the ***.

 

the car who i am building for is ona real budget, i am trying to go with the OEM stuff from other manufacturers to keep the costs down. as far as the injectors are concerned are teh stock dsm the best ones to go with with the resistor box, or is there somethign better.?

 

so no one knows?

 

I don't know if they are the best but they work pretty well. I run them and have had no problems with them at all.

 

how much power is the stock 91 integra pump good for
at 12:1 afr?

 

what about going with a turbo dsm pump? direct fit pretty much for a honda.. that's what I plan on running. My friend runs one now. Anyone know any problems with doing this? plus you can pick one up for like 20 shipped on dsmtrader

 

i have heard from dsm owners that their stock pump sucks, but i donno how much they know anyway so...
