A little advice please

[YEEE85]

I'm about to go ahead and pulled the trigger on a 212 roller cam, champ heads, champ ported intake and convert to E85 with a hellcat fuel pump- I will be doing the ECU and scan tool plus broadband as well so I can do the job correctly and stay safe. At a later point I plan to get an engine built with all the good stuff and a built trans, but for the time being, this should be a lot of fun.

What I've realized lately is that I may be able to make a little more power with this combo than I probably should on the stock block, internals and trans/rear.

If I'm looking for an acceptable horsepower range, how will I know when I'm approaching that point? I will be doing the drive train upgrades later too, starting with TC, Diff, and trans cooler, than built trans, than built motor- but as we all know this stuff isn't cheap and I will have to do one thing at a time and I would strongly prefer not to destroy anything in the process- at least not quickly
I don't plan on beating on it too severely, but I will get squirrely
Would there be a suggested boost level I could shoot for, tune for that level, make it run good and have some fun while staying on the safer side?
Or am I worrying too much
Car is an 85 GN staying hot air, with 40k miles, new aluminum radiator fresh timing chain and gears otherwise stock,
about to get:
works 5857 turbo, 3" Down pipe 3" exhaust 87 ECU LT1 MAF 160* stat Champion ported heads and intake, Comp Cam 212 Roller Cam, Roller Rockers Hellcat pump, 90# injectors for E85 (Too much?) + Electric fans and whatever else I can think of
This does seem like a lot to throw at it all at once, so I'm taking my time doing research and seeking sound advice and I do listen to advice.

How much power and how fast do you want to go?
See parts are chosen for performance goals
Your lists reflects parts that aren't ideal for anything other than emptying your wallet.

For as much as you are going to spend, don't do it. Build an intercooled engine instead. Upgrading a hot air is not a great use of funds unless it is super important to you.

Other than the hot air part, where am I off here?

If I were keeping it non intercooled I'd be looking at spraying a bunch of alcohol into it to "intercool" it with chemistry. Unless you are having some kind of cam issue that isn't going to get you much if anything over a stock bumpstick. I didn't do any math but I doubt the 90# injectors are big enough to feed the e85 in a meaningful volume.

If you are just wanting a fun tire spinning unit a torque converter and more boost with the alcohol injection should do plenty with that bigger pump and injectors. A power logger or aftermarket ecu to be able to keep the rods and mains in it would also be a way better spend that cam and heads. Turbo Buick is different than that mustang/camaro your buddy has.

 

[YEEE85]

This is why I like this forum people keep it real. Also finding lots of solid technical advice from some folks with major expertise. Do you have a torque converter you would recommend?

There is no way to know because the op doesn't answer the question of how much horsepower he wants to make

 

[THensley]

I don't know hot air car. But hellcat pump and 90s is a bad combo
Like Mr spool ask how fast? I ran 5857 with 60 and 255 pump on gas and ALKY low 11s A set of 120 and a 450 pump for E85 is probably all in with a 58 mm compressor OE stick is small but should go 11.5 I think the works58 mm probably good for 450 hp rated 550 and that's asking a lot for hot air car

 

[V6sleeper]

Just state your goals with the car and everyone can help you with the easiest and cheapest way to do so.

we know pretty much what every combo will do before it is put together , think of us this forum as the Turbo Regal crystal ball office

I want as much as the stock motor and trans can handle under reasonable driving conditions. Am I going overkill on the parts to do that, or does the combination I listed not work well together?

The stock motor can take alot more than the stock trans can.

Makes sense. 400-450 is a nice round number that Ive had in mind because I know what 400 feels like. Nothing crazy. But I understand these things make lots of torque as well. it would be nice to have things set up where I can dial it up later with a stronger trans and rear.

 

[YEEE85]

Seems like everything below the intake should be the same so if I want more power than I can make within reason I will probably go to the 86/87 set up with a strong foundation already in place then really turn the screws. For now this seems like a good place to learn. Asking dumb questions is cheap doing dumb things isn't.

The block is different. 14 bolt pan and front cover on 84/85 hot air, 20 bolt pan and front cover on 86/87 intercooled. Also block is not tapped for turbo drain on 84/85. You can use the hot air long block and all but you will have to tap it if you replace the intake/headers/downpipe and convert to intercooled.

 

[Mr.Spool]

They make alot of torque at a very low rpm especially with higher boost and they will take out the trans.
I would recommend using the search function here about the various combos that many have run.
Also put together a budget that your willing to spend because it gets expensive quick with these cars now.
Prices are up and the cars are approaching 40yrs old.

Dude you need a goal for what you want to do with the car.

This is what I want to avoid- taking out the transmission. Maybe that's a better place to start. I've been looking at a stage 2 from G body parts. Not cheap but not super pricey either. This way I don't have to worry later.
