Default Poll - stay FI or back to n/a

I am curious what you fellow FI guys would do with the knowledge you currently have. My situation is my stock 346 is going south and needs a rebuild. After getting some suggestions from several members I have some options. A forged engine is too much money at the moment, so it is out of the options.

1-- Find a used LS1 shortblock (stock), put some 6 liter heads on it and stay turbocharged. Make about 525-550 rwhp

2-- Sell the turbo kit altogether, find a used LS2 (stock) from a vette or GTO, drop a cam in it, port the heads and go back to naturally aspirated. Have about 450 rwhp, and hit it with a 100 dry shot to make 550 rwhp.


I am curious what you guys would do and why. The poll won't realy influence my decisions, but I would still like to see what other guys think. Pete.

Its all about budget bro. Do you have the money to stay FI? You already have a turbo kit and its running. So far, both of your choices involve FI of some sort. Out of the 2 choices, Id stay with the turbo. Both choices have you with a stock motor. Both have FI, but the turbo is the most fun without throwing more money down the drain to always fill bottles.

Not sure what you mean by saying both choices involve FI. If I choose to go n/a then the turbo setup will be gone.

As for budget, I don't think my 2 choices are very far apart in price.

id keep the turbo setup, and just keep the power level down to 500ish until your budget allows you to start pushing it again.

the stock LS1, assuming a proper safe tune, should last a long time at that level.

No votes for n/a so far? I figured you guys might be biased, but I thought 1 or 2 would vote n/a. Keep the comments coming.

i disagree, your not forcing any more air in there, just using a different molecular structure to power the motor. nhra lists nitrous as n/a btw

you could get a stock 5.3 shortblock, with the 6.0 heads compression is like 8.6:1
Mine seems to be doing fine and i was going to build a bigger shortblock, but its way better than I thought it would be. 5.3s are dirt cheap also. I paid $500 for the complete engine from LKQ on ebay.

Actually you are forcing more Oxygen in there... Off the top of my head, air contains 3.xx parts of Nitrogen per oxygen molecule. When you spray nitrous (N2O), you inject more oxygen into the engine since only 2 parts of nitrogen per one Oxygen is injected. This allows more oxygen to be squeezed in the cylinder. So yes, you dont force more air into the engine, but you force more oxygen into the engine (and oxygen is what is needed to burn the fuel).

OK, I would rather not have this an argument over nitrous being forced induction. Let's just nitrous is a power adder, just like a turbo is a power adder.


Anyway, let's add 1 more option to the mix. Since I don't know how to change the poll, just post up your opinion.

Option 3-- Sell turbo kit, but a 402 stroker with L92 top end and make about 550 rwhp n/a

The more radical N/A power you want, the more you will lose drivability and gas milage goes in the toilet. Benn there. You can have 500 hp with the turbo kit and drive around stock.

well i voted na w/ dry shot, here is why.. the cost.. ok i am done.
seriously ( for me at least) unless its a car you plan on keeping for the rest of your life(or a speciality car) , its easier to sell with and easier to take of the nos than an FI system , also quicker to sell the used parts. fun factor is still there, coolness , thats a matter of opinion.

Since you did bring it up, I do not plan to sell this car any time soon. I have wanted a WS6 for a long time. Even though I want a vette one of these days, I will wait until I can afford the vette without giving up the TA.

I'd stay with the turbo setup. You already went through a ton of BS to get where you are with it, might as well stick it out. A stock shortblock with low mileage can be had for ~1K and the LQ9 heads are about $200. So if you can afford the $1,200 and stay in the game, go for it. Of course theres still gaskets/bolts/misc stuff that adds to the cost, but I digress.

Off topic but I gotta add my 2 cents on the nitrous issue. Nitrous is not a form of forced induction because you are not forcing induction. The natural aspiration of the motor draws the nitrous into the motor. It is a power adder, but definately not a form of FI.

nevermind that N2O comes out at 1000+ psi....
