what to do???????????

1987mustanggt · December 29th, 2010, 10:47 PM

ok i need to know what sounds like the best choice????? i was thinking of doing a 351 with twin turbo's but only cause the 351 blocks r cheaper but i heard its heavier and more complicated to install right????OR buy a boss block and stroke it into a 347.. BUT the boss or dart blocks r expensive and im trying to save some money...or should i just leave it as a boss 302 without stroking it....????? i want around 400 to 600rwhp... so can it be done without stroking it?? should i make it a 351???? u guys help me out..?

1987mustanggt · December 29th, 2010, 10:49 PM

THE things that i have right now r the turbo's,some headers,all the turbo lines.some msd wiring.and ignition system.mickey tires on the way.and some other small stuff just cant remember right now..

How much money are we talking here? And if this is just future fantasy build, please don't waste our time with these questions. There is a million and one ways to get to 400 rwhp, but 600 is lots more expensive. And there is one hell of a difference between the two. So, which do you want and what is your available funds that you have right now.

1987mustanggt · December 29th, 2010, 11:36 PM

ok the budget doesnt matter.....the way i want it is with trickflow heads a tremec tko600 trans and all the other goodies i need..i know imma spend around 7,000 to 8k but the more i can save the better... and its not a fantasy build its the real deal..heres pics of turbos for proof and this my car

Uber88GT · December 29th, 2010, 11:39 PM

Figure out your end goal, street/stip...what the headers are actually made for and go from there. What are your plans?

1987mustanggt · December 30th, 2010, 08:57 AM

just want something for street that i can use once in a while and the headers came with the turbo's they were on a mustang before they got to me..

your car looked better when it was white.

nolife · December 30th, 2010, 09:42 AM

I don't know much about turbos but those things look extremely small?

I liked it better white to. But the new paint job would look good if you had not painted your wheels. just my opinion

Go for the 351.

Av8tor · December 30th, 2010, 12:46 PM

400-600 is a pretty wide range to be shooting for. You should definately try and narrow your goals down and be a bit more specific with what you want. Those turbos may even be a bit small if your shooting for 600hp. Im guessing they are just 2 of the turbos of a 2.3L turbo mustang, tbird, xr4ti. A friend of mine made just under 400hp with those turbos and a mostly stock 351 just pushing a load of boost through it.

1987mustanggt · December 30th, 2010, 03:32 PM

ok fine i want around 500hp..what if i went with trickflow 170cc heads a tremec tko 600 tranny with a 351 and a trickflow intake not sure which one yet. and turn the boost anywhere from 12 to 20 lbs.with idk some 42lb injectors?? where should i be with that?

ohh the turbo's came off a silvia..

AdderMk2 · December 30th, 2010, 08:35 PM

why such small heads? If you are gonna throw down the cash for aftermarket heads, toss on some TFS FAC 190cc heads

StangBanger302 · December 30th, 2010, 08:45 PM

What adder said. And honestly, with a power adder such as a turbo, you can get a lot of power without serious motor work. Mild H/C/I fox's with a turbo are putting down anywhere from 440-500+ RWHP.

At least those on a 351...

nolife · December 30th, 2010, 09:43 PM

Anywhere from 12 to 20 PSI? That is a HUGE difference, night and day and probably about a 300-400 HP difference between them. The larger the engine, the more impact boost has, adding 10 psi to a 2.0 liter 4 cylinder will yield half the power increase that 10 psi more will give a good breathing 5.0. Again, I don't know much about those turbos but you may want to look at the specs on those and see what volumes they support.

Boost is what if left over that did not make it into the engine. The larger the engine, the more air it consumes. That is why smaller engines need more "boost" to get a good airflow and make power and larger engines need less boost to get the same % power increase. In effect, less boost still gets the same air flow increase. Turbos and superchargers are sized with that in mind. A small turbo that can make 20 psi on a smaller engine may only be able to efficiently generate only 7 psi on a larger engine. I pulled those numbers out of my ass but if you just wing it and assume, you may be highly disappointed.

A single correctly sized turbo 302 with good heads (TF/AFR) making 8-10 PSI can easily make over 500 RWHP and probably have over 300 ft/lbs torque at 2000 and at that HP, the stock 5.0 block is on borrowed time. That is why people are asking what your HP or $$ goal is, that is the only way to give decent advice.

1987mustanggt · December 31st, 2010, 01:19 AM

well so far u guys have convinced me to get 190's then.with a 351??? yeah i think 500hp is good i just want a fast car for street and maybe strip once in a while.money wise i would like to spend 6 to 7k if more i dont care..labor aint big problem uncles r mechanics..SO should i be good then?
