Slowly but surely I am gathering parts for a tpi swap. I have almost everything, but my injectors are for a 305. I read that they are 19.3lbs @ 43.5 psi. Is this true? Is there any way I can use these in my 356 application?

 

if you get an afpr and boost the pressure, you might be able to fake it for a bit, but your best bet is to get some 22 or 24lb injectors.

on a side note, i just bought some type III bosche (rebuilt with 3 year warranty) from fuel injector connection. damn good prices, and u can't beat the warranty

 

Does anyone know offhand how uping the fp affects the flow rate on injectors?

 

More pressure more flow. There are calculators on the web/tgo, to figure the difference.

 

I just ordered today also.. I'm having them shipped for sat. delivery. i will tell you tomorrow night how it runs. Nice people very helpful..

 

put in the 3rd gen bosch.. big job because i detailed the engine. just got back from an hour drive.. car runs great.. easy starting no more hesitation
thanks jon!!

 

How much did the Injectors cost you?

 

i bought the flow balance set. 169 for all 8 3 yr guar.
heres the link of their store
www.fuelinjectorconnection.com

if you call ask for jon

 

the 19lbs injectors will WORK at an high pulse width and they will get bad faster.. It will work but you will shorten the life of the injectors, and also If you got an stock tpi intank fuelpump dont go over 50psi (because that will hurt the pump over a long time..)

If you have the $$$ in some near future, buy atleast 22lbs then (or bigger and change the injector constant in the prom.)

take care.
