Best set-up plan for 750 RWHP
Best set-up plan for 750 RWHP Hey everyone. I am going to work and build my car up into a street machine. My end goal is one sick looking ride with 750 rwhp. Heres the order of stuff ill be doing...... but i dont know what compenents would work best to get me there the safest/easiest.
-turbo kit, im going to get it, bolt it up and run 8psi for now on stock block
-forge motor or buy a new short block
-swap out 4l60-e for a built T-56
-12 bolt
-up the boost
Now.... i know the higher boost will require a much more adavanced fuel system so i plan on doing that when the forged motor goes in. So..... What turbo kit should i look for..... turbo size and specs on forged block or a new shortblock? Remember..... Safest way to reliable 750 rwhp on street car. Thanks

GAAAA, but could i buy that kit and safely run it on a lower psi?

You can always run it at a lower boost setting....The plus side to the twin setup is that you'll have a little quicker spool time compared to a bigger single turbo...there price is very affordable considering that it was JUST produced and how complete it really is...
Well could i drop that kit all the way down to where it would be safe on stock block? Also whats the cost for the full out 370ci forged motor plus Twin kit and fuel system all in car and tuned? Thanks

Expect the setup you plan to build to add up to alot of $$ first.I would figure $20g if you do most of the work.
The GMR kit look promising but I haven't seen to many people running them yet.
For a motor I would go with a bigger cubic inch setup so you can run less boost for more power on pump gas.
The fuel system will add up too.Big pump,line's/rail's ect.
For comparison we ran a 8.5-1 408ci with AFR heads,220 Cam and a T88 to 820rwhp on pump gas so far (14lbs) but ran out of pump.We expect a good 800-900rwhp daily driver and 1k+ race setup.
Now,expect alot of bugs to work out too when getting the setup to work and expect parts to break.

2500 for a 346 is about normal, along with 3000 more for a truck manifold kit(with air to air and S76), followed by the t56 which i have no clue on but that clutch is gonna be expensive, a new rearend should be around 2500 also, then the fuel system dual walbros, hardlined 1/2in line, new rails and regulator, prob around 1000. Then tuning so about 1000 more(includes fp, and wb02 guagues) then little things like, slicks, oil pressure guage, egt monitoring, driveshaft, spark plugs, dyno time, install($$$$$$).
Iono, thats what ive found so far. And switching from an auto to a manual will be expensive. your prob gonna want a ls6 intake and new tb, valve springs, heads. AND THEN TO TOP IT ALL OFF, YOU SHOULD DOUBLE THIS AMOUNT. If you wanna still go FI your a brave soul. 10k not including the T56 which will be at least 2500 more, or heads and cam 2500. so 30k with the FI 2x multiplier.

ok well i know the numbers for cash are going to be high so thats why i want to work into it. I want a nice kit and run 8 psi o nmy stock motor so its safe. Then i want to forge my motor or build one and upgrade driveline. So would you suggest a single kit or a twin? If i were to go with the single, my idea would be that to support 750 rwhp ill have to have a big turbo and a very pricey kit that wont be all that friendly on low boost. Would twins be better? I also got a quote from EPP for $4500 to pull my motor, forge it, put it back in, dyno/tune it.

The whole setup you're talking about will run you around $16K with GMR. I love the twins on the street, don't have to wait for the power, it's right there. I wouldn't ever consider anything but twins for the street. You could run it (psi) as low as you want if you're running the stock shortblock for now.
Ok so i could go to GMR, get the twin set up and basic fuel set up for now and run it on my stock block. Then later when more extra funds roll around, send my block somewhere to get forged and upgrade the fuel system so i can achieve more power.... Sound like a plan?

Yeah, but the $16 I was talking includes the new forged motor, install, fuel, twin kit, tune etc. The complete setup. Given that the stock shortblock is only reliable at 500-550rwhp, you don't NEED the 1000hp fuel system. You'd be good to go for the time being with a $100 walbro intank pump and some 42lb injectors.
Yep, thats what im thinking. I could probably get the twin kit and the street fuel set up they have have run that on my stock block for a while safely for under 10k done. Then i could swap out my 4l60-e for the t-56 and get a rear end. After the drivelines all set then ill forge my motor, bump up the fuel system and ill be all done. So this will ocme in steps so it wont seem too outrageous if i spread it out. lol. But then i will have my dream car and one of the best street set ups out there!

Or would i be better off/more reliable with like a Phamspeed single kit now on streek fuel system and forging motor and so on after? I think i like the thought of twins the best...... I hope GMR steps in here and can tell me how it will work on low boost for a while.

I say twin turbo and the GMR kit uses 2 44mm wastegates so you'll have no problem bleeding off all the pressure. Could probably run at 5psi if you wanted.....but once you get a taste of that you'll be wanting to triple that boost pressure! It's addicting!! lol
What about spraying a little nitrous into a big single (76) ? Wouldnt that work as well as twins.
What do you want to keep on the car? For a street machine for me i would like the ac ect.. Of course its a lot hotter here than there. The hi-flo /hp kit look good to me.

yea thats one thing im debating right now. With the twin kit i cant keep AC. of course car is not driven in the winter and will be driven only about 7 months out of the year. It doesnt get unbearably hot here in MI but i like to use my AC, however if its worth going twins..... i can do fine with just t-tops. I am not into nitrous and dont feel like using it. Any other options....
