Building the best FI motor? Ok I need lots of help I want to build the best FI motor. I would buy rob's but it is tax time for me! But I am basically looking for the same thing. I want all the power but in a street car so I think I will just adjust the boost. Why bore it? and if so why not 427ci+? What is the Incon kit max boost (16)? So tell me what you guys think everything from cam,heads,block, and important parts. Any help would be great! Should I just call ARE? I have 73cfm 6.0l heads,5.7 heads,and stock ls1 & iron 6.0l blocks As well as 2 600hp turbos and 2 800hp incon turbos!

Re: Building the best FI motor? Oh I guess I didn't think about that, I have the walbro fuel pump and injectors 42lb. I want the best and if it can't run then I will change parts or turn down boost, as far as racing I am going into road corse, but street race every weekend so want the power. OH, I have a KTRE 12bolt with a 6speed and money doesn't matter after april!

Re: Building the best FI motor? It depends on how much $ you want to play with as well..
I plan on doing a cheap 346c.i. build up.... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
But it will handle 15psi..... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Building the best FI motor? Well I plan to spend 4000 for my motor build up, probably a little more all depending on what little parts I decide to add while I'm in there..
Always get caught up in the "while the cars in the shop I'll do this" type of deal... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Building the best FI motor? so the 346ci is the cheapest way go,no rebore/resleave! But power levels at what mid 600hp! That is about what harlen has a forged 348ci and Incon twins! That sound good for now... What can be done to NOT lift the heads and is ringing the heads to keep from blow out?

Re: Building the best FI motor? How come your converting your car into a drag car, or you still want it xcross?
you could do something like Harlan, built 348 with 700rwhp, this will keep the car lighter, but if you want 800rwhp+ you'd need 400ci+ probably an iron block would might hurt your Xcrossing ability.
Why not get another car and build that into a street/drag car?
or can make you current drag car streetable and use that.

Re: Building the best FI motor? 800rwhp = built motor, 83 lb injectors at least, and an aftermarket pcm to control it all. You will need a complete fuel system as well, like dual intank pumps or a big external pump like the Weldon 2025 that I will be running.
You can do a 400ci motor you will make more power NA than a 346ci and then can make less boost to hit the same number.

Re: Building the best FI motor? Hey I am still autox with that race and have my1000+hp drag racer but what lots of power for my street/autox car. Allright I will go with A LS6 348ci forged block with stock big ported heads. And shoot for a max of 700hp. Thanks guys!
