I recently had a few guys ask me about modifying the mpi intake so I dragged up this old thread. I have since also bored out the throttle body and had the intake full ported. Last time on dyno we made 1115 with the blower and 657 NA, Smitty

progress on my intake's ..... I guess this is first stab at it ...fuel rails are going to need some more work ...port side ended up too close to the Distributor .... I'm thinking now feed them from the front and put a return about midway inder each rail ....or ...open to suggestions ....
Smitty ... those are your Deka 80lb injectors .... No 1 long block should be ready in the next cpl of weeks and hopefully can start rigging the motor ...m

I modified my stock fuel rail by taking a long 1/2" drill bit and drilling all the way through the rail and then opening each injector passage to 3/8". I then tapped each end to 3/8 pipe thread. I also tapped the side hole to 3/8 pipe to use as a return. I will have to feed it from the front as there is not enough clearance between the rail and distributor in the rear. Wasn't difficult at all, took about 2 hrs to complete.

Is it really worth it when you can buy something like this, http://www.ebay.com/itm/FAST-INTAKE-...55b421&vxp=mtr

I would definitely say yes it is considering you have to buy another 500-1000 worth of crap to make it work. So yes a few hours of grinding is way cheaper and worth it to me I'm cheap deal with it.
