Hey guys. So ive got all my running problems squared away on the mustang. I am thinking about a power adder, which I believe I want to Twin Turbo it. I can custom fab a fair amount and am thinking about getting a basic kit with 2 turbonetics turbos. Im not really sure. I want to run low boost (8-12lbs). But heres what I have going on the motor.

331 Stroker Roller motor
all forged internals
molly rings
trickflow track intake manifolds
.500 lift cam
GT-40 heads
stock block
high flow oil pump and cooler
and a few other goodies.

Has anyone heard of adding this setup to my mustang? Im just collecting information now, will probably make it happen soon.
If you can still hear to motor, turn up the boost.

8-10 psi should make over 500hp easy. Block go boom boom. :laugh2:

i agree with 1bad fox the stock block will be a very weak link , i have a 347 i would love to turbo but i didn't think about it at the time i had the motor built

Just go ahead and turbo it! Keep the tune and boost safe and the block will last longer than u think. Then once it does finally crack a block build a good block and crank it up!! Im running a stock internal stock block 306 with TFS HCI and Its been on 12psi with the blower for a year driving and running the piss out of it daily, the turbo setup i have now is on the same motor and its still running like a champ. :cheers:

Why not just go with a good sized single? It saves money as you dont need as much piping or two blowoffs etc. I know Twan on here 93blackfox, has a badass B&G setup, complete ready to bolt on with all you need.

I was thinking the same thing when I noticed he wanted to run such a low amount of boost.

We haven't broken a stock block nor had a customer break one in over 5yrs and have built dozens of 500+rwhp combos......

Tuning technology has come a LONG way and if the engine doesn't detonate and the RPM's are kept in check it will live a LONG time.

In fact if the engine is kept under 6000 RPM it would be very very unlikely to break a stock block with a turbo even at the 600hp level.

Thanks for the input guys. I guess realistically I would like to run 5-8 lbs of boost. low boost.
I thought about going with a single turbo, but 2 small turbos will spool so much faster and with low boost they will be more efficient.
If you can still hear to motor, turn up the boost.

Man O man. I would never buid a turbo car for only 500 horse and under 6000 rpm. Thats only 400 to the wheel and in a heavy car only low 12s..high 11s at best.

My stick car ran 11.1 @128 On 8psi, and its heavy, 500 hp can get u into the 9's in the right car, people do it with stock shortblock 302's in light auto cars.

Does anyone know were to get a decently priced tt kit? Nothing crazy just something good for low boost with prebent inter cooler piping?

For the best reliability and price i would get a properly sized single setup, Ive heard of some singles that spool as low as 1900rpm on mustangs and they make great power. Twin setups seem to be a lot more work and u will need a bunch more stuff to get it finished. Just my opinion on this, do some research and talk to people with setups you are interested in. :cheers:

Its not a tt kit, but check out On3 Performance they make a nice kit for the money.

Just think of this, originally set twin turbo cars always go to a single turbo, that tells you something

+1 on what rick says, my friend converted his stock tt 93 rx7 to a single big turbo. he had to many issues with the two turbo's then its twice the money and twice the parts. plus there is more engine bay room now and more reliable.
2nd place is the first loser
