300 rwhp safely

First allow me to apologize for not posting pics yet since I recently started posting, just got a camera & will get some up asap. I also forum searched and didn't find exactly what I needed, sorry if this is repetitive.... :D

I have a couple more things I want to do first (pulleys/suspen/shift kit/couple cosmetics), but engine mods are right around the corner for me. My goal over the next year or 2 is to reach 300 rwhp with no power adders. I want to do this as safely as humanly possible, the car still has under 70k and I want to keep the engine running strong for a long time to come. I'm sure I'll be in the position of collecting parts over time, it won't be an all at once deal to say the least.

What direction should I start in and what do youguys think will get me there in the end. Thanks for the help!

Start by researching cams then match the heads to that cam then match an intake that can support the air flow. Next move on to the fuel then exhaust then dyno then have a nice day.

thanks, and by fuel you mean pump & injectors I'm guessing, and by exhaust youguys mean I'll need headers? That's all I'm missing on exhaust.

Looks like there's no especially unsafe or especially safe way....but I'll start w/ the cam search. Is a chip going to be necessary before the tuning? I've seen similar setups on other cars around here only pushing 270-290 rwhp, think these things alone will do 300 after a tune? Sorry for the TONS of questions....
 
You and I have very similar plans for our '94 GT's (big fan of n/a power). Personally, I'm more of a Trick Flow person to an AFR, so I'd reccomend starting to look at the Trick Flow kits that summit offers.

5.0 EFI kit
Summit #: TFS-K514-350-370

5.0 Track Heat
Summit #: TFS-K514-360-350

Probably should run 30# injectors and a larger mass air (chip or computer reprogrammed).

You can get more power out of the Trick Flow heads if you have them ported by someone that knows what they're doing too.

Before you start running 300rwhp, you may want to upgrade some of your suspension starting with sub-frame connectors. The *proper* way to do performance mods is to upgrade the suspension first, then the drivetrain. That way you always have a car that can handle the power you're putting out.
 
A chip comes after the dyno is performed. A chip just keeps the tune in working order. Like other have mentioned a EEC tuner can be very handy "if" you plan on tinkering with things later on meaning you can swap out a part and use your tuner to reprogram the puter to that new part. But if you plan on hitting 300rwhp and leaving it be then a chip will do just fine.

I don't see how you could include all combos in that hp range together and be able to tell anything that would help you. There are too many things that can be misleading.

A combo would have to be pretty far off tune to go from 270 to over 300 with just a tune. I could happen but I would not count on it.

An example to the other extreme would be my car. A tad over 290 and the tune was right on the money but the tb & maf were too small to make it over the 300 mark.

Just search for all combos that meet your expectations and take a look at what they did to get there.

If you really want 300 or better then don't buy the wrong stuff, or stuff that is too small, and the like. Don't fall into the trap of buying something just cause you can get a good deal or you run across some heads that were used buy a guy that ran 10.xx in the quarter.

Have a plan and stick to it. You'll get to your goal.

Don't forget that it has to pass smog here in Cali... :( That will limit your selections, as they have to be CARB legal.

Gonna have to say that I've not found that to be the case with my car and others that I found on some of these forums. :D

We are talking about a street car combo that can pass emissions testing.

The egr does not cause a loss of hp.

A good cat pipe does not cause that much of a hp loss.

The smog pump can rob a good bit of hp but when I've seen others talk about that issue they usually said the pump was old and did not operate like it shoud thus causing a more than usual power loss. If the pump is is good working order it does not pull much power.

You being in Cal might mean you can't run lt's but you still can reach or break the 300 mark with smog legal shorty's.

IMHO you can reach your goal and still be smog legal but you might have to be a little different in your approach to get there.

btw ...... I run all smog stuff on my car and have passed the dyno roller type emission inspections since 1997. Every year the tech said my car tested much cleaner than the average car. :nice:

Good points Grady! :)

I probably should have been a little more specific. It definately can be done, you just have to be more picky about what parts you use, if you want to pass the inspection.

I have always thought it was a joke, when our cars are better maintained and run cleaner than some crappy grocery getter, but fail because of a "non-CARB" part! I thought the spirit of the law was to reduce emissions. :)

I was concerned the first time I took my car to get inspected after the custom cam, 30's, lt's, etc. After the tech at the inspection station told me it passed with very clean results I let a friend who used to inspect cars look at the resusts and he also said that it had very clean numbers.

Again I don't know if you guys could get away with lt's cause they don't have that CARB number you talk about.

i would look into the Trickflow kit as stated before. its a good kit with everythign you need except new lifters(i think). they say it makes 320 hp at the fly and 350 tq. which is very respectable and if you have enough suspension mods that will be all you need. unless you are just trying to reach that 300 mark just for pride. i dont know if you have an auto or 5-spd, partly bc i skimmed bc im taking a break from studying for finals. but if you have an auto you might want to look into gettin a 4R70W tranny with a 2200 stall. i believe i found one with a stall for less than 2k then like 150 for shipping and however much for labor.

the kit i think is the easiest way to go bc you get everythign at once and it is all matched. to me that is more important than finding the best parts of each. besides AFR 160s are almost 2k by themsselves. good luck!
