The problem with that turbo is that the waste gate assembly sucked on mine and would stick open and not close. May wanna get the boss550 rear housing if that happens. good luck grim!:)

Like that turbo spooling up sound dont ya....sounds like a jet plane about to take off.

Watch that wide band like a hawk.:naughty:

I found a source that makes the insulator, but got it from blackdevilsupra, and never kept it. I will find the info an post it.

I hear that bosch pump is top notch and works great period.......

I simi posted earlier in the thread about this procedure. If needed I ll see if I can dig up part numbers needed. Just take the stock hanger and drill out the return, nd put a 90 degree bulkhead fitting. I used this as a return and my fitting was a -6. The lines to the rail on the tank was...

Wise guy.....I get yours all the timme.lol:aigo:

Well now I gotta give JD the love back, believe it or not we have been adversarial a few times, but we respect one another it seems. Knowledge recognizes knowledge. You just need to chill out. The information all three of us are passing on to anyone that chooses to believe, and hear it is that 1...

The hardest thing was messaging the tank to a larger opening to accomodate 2 pumps. The outer edge I cut wih metal shears, and less than an hour was done. Get insulator to kill magnetic interference and install on stock hangar.Get 2 30 amp relaya and wire to battery, and original wires for key...

I found a company that makes nothing but inline connector check valves for air water and fuel. I got one to plumb to my idle speed control valve to keep the external valve from losing air under boost. The valves unseat at .002psi and can be used up to 1-2" inline connections. I just have to...

I got a heater hose that goes across the back fire wall and u turns and j's into the heater core to alleviate heat fracture failure.

I already sourced this out....finally found a place that has them 1/2 npt inlet outlet. Now to wire up a fail light signal as well.

Agreed.....Thats what I did dual feed lines isolator and adirect wire with relays and all.....:naughty: :biglaugh:

I have heard to do this you need to not have the internal pumps connected or the external pumps will eventually fail. Anyone ....Ian.....?

Welcome to the darkside of boosting gt4088 style.

dont do it 550-600rwhp on a walbro is asking for trouble. Its rated for crank hp of 500-550 which equates to about 425-475rwhp dude.

Well we know its rated for about 500-550 crank hp and if we get 600rwhp and blow up it still made it....So there Ian.lol:naughty:

Thats pushing it, and If you go in the tank now knowing youll need it later, and not put two pumps in is time consuming and futile. Do it once and forget about it. Same time a little more effort and no more worries until something comes up. Not to mention fuel pumps and injectors usaually are...

If you have a 3:" outlet on the IC use 3" IC piping. Why go to a large tb then restrict it with a 2.5" tubed inlet. It will be very responsive trust me.
