Your going to run into quite a few problems with this build.

1st forgive me if some of this isn't spent right or is missng things.
I'm doing this from my phone while on vacation.

I have the build you are discribing.
98 PCM tuned with HP Tuners with a piggy back.
Its called a MAF T-Pro and it controls the fuel signal to the PCM.
I'm also runnng an injector driver box to control 96# injectors.
An iron 370 W/ a stock crank eagle rods and diamond pistons.
reworked patriot 317 casting heads and a gmpp carb intake.
A Stenod built S88 Turbo kit W/ there 4.5" thick A2A intercooler.
I'm runnng a rossler built glide after talking with him about the 1st gear in a th400 being to tall and a turbo caraking enough TQ that it loves the 1.80 1st in a glide.
Who ever tells ya glide can't be driven on the street the same as a th400 is full of ****.
Daily drove mine with everything im describing for almost a Yr.
Aeromotive Pro series fuel pump with the fuel pump cntroller
the pro series FP regulator also.

Now the problem you are going to have is what most Big HP guys have. Liftng the heads and pressurizing the coolant system. I started to around 20-22 psi. Timing has alot to do with it also. I have plans in the work right now to fix that.
Cheap and big Hp should never be in the same sentence ......
its going to take some $$$$$ t reach your goal. When I around
a real Comp and not my phone I can link ya to my build and parts I used on my site. Maybe someone else will for ya. LOL

Both engine builders i want to use do o rings so I hope with a s91 I can get over 1100rwhp and the car should be under 3100 pounds full of turbo stuff. I will build another motor after i teat this one up learning about boost. thanks for the reply nasty-ta

Don't forget to budget for the unforseen crap. Plan on an extra couple grand of expenses popping out of no where! I don't know where they come from but you'll just be sitting there one day thinking everything is going good and, BAM! Outta no where. They are sneaky little *****!

Thats what I have and I never had a problem. I've never tried to run anything under 7 psi with mine. I've run as high as 26 with it.

what about doing all the stuff bs3 160 pound injecters and everything top notch but the motor. I dont think I can afford a 10k plus motor right now. I was going to do everything but just put a stock 6.0 motor in it. I wonder how much boost a stock 6.0 motor would take with a s91. I dont know if it would take 7psi like they do with the smaller turbos. I just want to have it done by the end of janurary. any help would be great

If you do a stock 6.0 I would still do aftermarket head studs.

You can wired the BS3 as a standalone or you can keep your stock harness and pcm and just do some splicing. If you the latter you can keep your stock gauges all functional.

For the wastegate and blow off valve, I 100% recommend you go with both Turbosmart units.

The ProGate 48mm is a great unit and can withstand TONS of abuse. I like it more then the 50 but only becuase you can get it in the sleeper series which is flat black top hat.

The RacePort blow off valve is an excellent option for the BOV. It flows really well, but I would recommend getting two of them to help with possible compressor surge issues. This also comes in the sleeper series, which is nice.

Boost controller could be either the AMS1000 or the turbosmart EBoost2...I have been impressed by both, leaning towards the Eboost in my car.

I am going to try to keep the stock gauges. I am just going to go for 5-6psi if I do a stock motor. I am not spending any money on the stock motor. Now i just need to find one near St. Louis

well my tuner wants me to pin a 99+ computer in my car. I am thinking about running the 160lbs bosches with a aem converter with the racetronic harness. If it is to much injector I will just turn down the fuel pressure for now.

That is a cheaper way out than a BS3. I would just add up the cost of the parts to make the stock stsyle PCM work and then see how far off you are from an aftermarket solution.

It may have been the tuner at the time...but I tried that and it didnt not work. The car idled like a alcohol car and wouldnt restart (due to min pulsewidth I believe).

I agree. Mine would give me a lil crap now and then with 96#ers.....
Id just add it all up and if its even close to $2,000 then just spend the $400 more and get BS3.
