Turbo 347?

I am getting my summer build plan going and need advice.I am thinking of building an good strong motor for the street with the occasional trip to the track.I want a turbo and was thinking of putting it on a 347.Is that over kill or would that work well?I am thinking afr heads(not sure on size yet),gt 40,forged bottom end.This is my first mustang and first ford so I am reading up but wanted some advice from the pros.How much hp do you think A well built turbo 347 would put to the street?

when i first started looking into turboing my mustang i was thinking of the same thing. i asked the same question and many people told me it was overkill. but i guess it depends on how much time and money you are willing to put into this and how street friendly you want it to be.

i suggest heading over to turbomustangs.com and reading up over there. you could probably build a stout 306 with a turbo kit and make plenty of street friendly power.

What are your power goals?

Its a good combination, but with just a stock block, you won't be able to turn it up much.

I will be upgrading the block also.Not sure which one yet though.I don't really have a specific power goal in mind.I would like to toast ls1's and some cobras on the street.Maybe have it in the 12's.

IF your goal is 12's, you can do that with a NA 347. I have been 11.82 at 121 mph with only a 1.96 60 ft times. All with NA 347. I have a turbo kit sitting in the garage right now and I am debating on whether or not to put it on. My CR is aroung 10.2:1 right now so I would probably limit the boost to around 6 to 8 psi. Whatever you decide to do, good luck.

So if I did do a turbo 347 I could probably throw myself into the single digets with enough boost huh?Maybe it is overkill.I would like a turbo so maybe I'll step down the cubes.

I would think that once I put the turbo on my car, single digits would not be out of reach. My only concern would be that I am running a Mexican block with a DSS maingirdle but I am sure the I would be pushing the limits of my block at that pooint. My goal is 10's with my car. I want to be able to drive it to the track, run low 10's and then drive it home. Now if I were to dip into the 9's, I wouldn't have a problem either...lol We will see.

Have you seen where some guys(Brent) are making over 1000rwhp with just 302ci turbo combos? If you just want 12s, heck even 11s, I'd really think things through because a turbo certainly is not needed for those goals.

11's would be nice.I would also like to drive to the track,beat a few cars and drive it home.It will pretty much be my weekend fun car as I all ready have 2 4runners and am buying an f350 in July.I don't want my wheels to lift off the ground or anything,just a nice powerfull car that can run with ls1's,vettes,vipers.

I think I would read around on kits from there. There are quite a few people complaining about the customer service from there.

Yeah, that's what I meant to say, I think I had a bout of ADD and just got distracted there

If you want a fast car to run with Vettes, Vipers, etc, go take your stock motor, and bolt on a turbo kit. When that seems slow, put some heads on and have more fun. My Wife's car is a Coupe, stock shortblock freshened up, stock AFR 165's, cobra intake, stock cam, T70 P-trim, 55 pound injectors, and a TKO. If you don't think 11.17 @ 126 on Nittos is enough to have fun with Vettes and Vipers I don't know what is Keep in mind that car will still pitch you sideways at 60 if you mash the gas, with all these 800, 900, 1000 RWHP street cars you see I think people are really underestimating just how fast 500 RWHP is. That's like 600 HP at the motor! Keep in mind that's a car she drives every day, it idles like a stock car and will sit all day long in traffic without stalling or overheating the fuel, it doesn't stink like gas, you can have a conversation inside the car fine at any speeds, the turbos make for a very streetable setup.

I most likely will buy a stronger 302 block and do the afr's gt-40 and then the turbo kit.Sounds like you have a good setup there.I almost got taken out by a turbo 240 sx the other day.I was starting to sweat it there.I need alot more power.

I am building up a Dart 345 (as soon as Dart ships the block, been waiting for 3 months for it). I had a 306 that I was running with 8-9# boost and turned the dyno 422RWHP at 466ftlb at 5K RPM. I was running the HCI that is in my sig. While I am at it to build a strong motor, it was almost the same price to build up the 345. At 422RWHP, that would put my crank HP near 500HP. I run the Mustang on open tracks for 20 min sessions. I didn't want to worry about blowing a block, so I decided to build it once and save $$$ in the long run.

What I would do, is leave the engine as it is and get the turbo. You will love the low end torque for a street car. Get used to tuning it with a fairly stock engine. This way if you hurt the motor, you are not hurting you wallet as bad.

1994 Mustang GT Chrome Yellow, Griggs GR-40, Tweecer RT, T4M0 with J4J1 Cal, 42# injectors, Pro-M Bullet, LC-1 w/XD-1, Dart Sportsman 8.2", 345CI, Edelbrock 6037, Cobra intake, Crane 2031, Steeda 1.7 Shaft RR's, Cartech Outlaw turbo, 422RWHP 466 FTLB at 8-9# boost on old and hurt 306. SAAC NW track days at PIR.
