aint that the truth.
My small incons made 735-750 rwhp at 15psi
my 88 makes the same power at 8psi so size does matter
turbos are more hassle than a s/c. Just depends on what you want. A s/c requires headers and generally a littly louder vehicle than a turbo vehicle. Turbos are a little stealthier but of course once you go to the drag strip, all bets are off. There is no BEST option....just one that suits YOUR needs/wants best.

I want to take my 2600-2700lb ls1/t56 rx7 to 10s (9s if I can get any traction) at 140mph with room to grow in the future if I can ever get used to a car that fast.
Car has 26" tires and 4.10 gears. I know its going to be expensive but I dont care to spend more money than I have to. I built the ls1 rx7 so I have some ability but I cant fabricate turbo systems or anything like that. Seems like used d1sc and p1sc kits are the cheapest options

from a price stand point if you haven't the ability ro tooling should I say to fabricate a turbo kit for your car and one is not available, then yes a SC is going to be the most affordable option for you. it comes complete and making it fit over a turbo kit would likely be easier.
but you'll always wonder what the turbo would have been like!

Umm ati prices aren't that cheap anymore .No idea on vortech and not many options for twin screw or roots types in our f bodies..MTI is going a kit and though other sponsor on here?
My aps kit was 5500 shipped and they are a bit more now. The install is long around 100 hours but not that hard really. Just lots of little things to slow you down here and there but it was complete ,every nut and bolt. And now that its in there very stock looking and stealthy.
So again don't see why people think the supers are that much simpler to install.
A roots or twin screw can be simpler but he once its installed its installed right?
And you can get the new sts kit for think around same or bit less than super and they are pretty easy install and trust me they work great, sound great and think the new upgraded kit has worked out most of the bugs of the earlier ones and buddy has early ls1 kit and he loves it so can't be that bad.
Why are turbos so complicated. Install turbo maybe take off oil pan not that hard support engine crop kmember no big deal..almost as easy as some header installs. Drill out pan for returns or oil goes thru cap on the sts. Hook up some coolant lines if your turbos are water cooled. Install an intercooler and run your cold and hot pipes. Its not that bad really. With a decent aps or sts kit. Hearing not so good things about those hp kits too bad they looked pretty nice on paper and nice to have more options.

I can get a used P1sc D1sc kit for 3000-4500$. The Ls1 GTO kit fits the Rx7 with minimal modifications.

yeah with your platform no the aps kit is not for you really. And yeah used super would work pretty good not all that hot side piping .Agree for you likey a super is easiest.
Or forged up NA with spray..408 or 402 are nice sizes in 6.0 iron or ls2 aluminum or maybe l92.

I was pretty sure I was going to do a custom turbo setup but my tuner is well known in this area and on this board.. and even he seemed to like prochargers over twin screws and turbos. (he felt twinscrews were great but produced power in a manner that made it difficult for most people to get it to the pavement on a street car, and I dont really know why he didnt like turbos I forgot what his reasoning was) He felt that generally prochargers were easier to get off the line than anything else, they produce a power curve thats easiest to manage, and generally run better times at the track because of it. That kinda threw me through a loop because I wasnt expecing him to say it.

sounds like the profit margine for invoice/cost could be
hoodwinking the build for said project.
my money, my build,...i was never a fan of
hey, you should be greatful i would build this for you,
it's more like... ummm,? excuse me, but you should be thanking me
for spending my cheddar hurr'. ya~mean!?
but that's just me. nothing beats a turbo.
now if thats a fact, tell me am i lying?
cuz you my friend, are leading this build.
don't get swayed by opinion. do it once, and do it right.
good luck in all your future endeavourse!

Looks like you are just repeating what you heard somebody else say because it's not factual information and you obviously don't have any experience. My combo is about as simplistic as you can get as it's just a stock cube motor with a average sized turbo (T76). My powerband goes from 3700 rpm to 7000 rpm as I let off early on that graph I posted and that's on a non-loaded dynojet and it's better on the street/strip. During a race I am really never below 3800 rpm nor am I below full boost.

Um, yes it's obvious you have no real experience with turbos and lets add mustang dyno's to that list. A mustang dyno can apply more of a load than a non-loaded dynojet and that would make the boost hit earlier "showing" an even bigger powerband to a turbo car. But what do I know, I only tune turbo/supercharged cars and use a dynojets and mustang dynos pretty much every day. I think you should just leave the thread.

, but this was on my truck when I only had the 4.8 with a 210/218 .551 116lsa cam, meth and a MP T70 turbo on 11psi of boost and 91oct gas. Not bad for a baby motor and cam

I was there the day NicD made that dyno pull and it was hard me for to swallow that he made 800/800 with his setup, but I have to believe his numbers if I want to believe mine. This dyno sheet was of my truck on the same day. He had already left, so he probable doesn't remember a stupid truck guy, , but this was on my truck when I only had the 4.8 with a 210/218 .551 116lsa cam, meth and a MP T70 turbo on 11psi of boost and 91oct gas.
