Thanks for all the posts, but i'm not quite sure about a few things.
1.What kind of bottom end should i be looking at. Me not knowing alot about cars, what exactly am i needing. From what i can [U]guess i would say it can't handle with more than 7 pds of boost. a new BE would do what for me and cost about how much? Also, is it hard to install yourself.
2. After reading the posts, i think i want to go with a procharger, meaning i need heads, bottum end, and a couple other things, but i also would like to put a smaller nitrous system on as wekk. What can i look foward to getting? what shot and problems that will probably come with the new found power.
Thanks again,
Chris... who needs to learn about EVERYTHING.

 

lol i like the last bit of that post "who needs to learn about EVERYTHING". Anyways i think you should just get a forged bottom end nothing like what i got but something like forged rods, and pistons, and a good set of heads, your cam is a good force fed cam that will work good with the nitrous and sc, so dont change that. I wouldnt go all out on just forged stuff, i would just get the basics for the boost you would want to run, then put at most a 75 shot on that then call it good.

later

what it looks like to me is your cam isnt "well" suited for nitrous or a super charger....
nitrous and SC's needs more exh. dur. than intake dur.
SC's typically i think 4-6 degrees more
nitrous can work almost with any cam but works better with more exh. dur.
SC need a higher lsa for example 114.... N20 will work with 110ish and higher...

so if you're looking to maximize your performance you would want to swap cams for a supercharger

 

You'd better budget for a new rear end if you haven't already...

 

With the financial limit you stated, I voted nitrous. If you had a very big budget, turbo. If you really want to go fast, plan on spending as much on drivetrain and suspension as you do for the motor. You'll be amazed at how quick you can go without a ton of power.

 

I got a question which pertains to both options.

I have only run NA (which is about to change -N2o). My Z is slower in the summer, which of course is to be expected. Blowers/turbos tend to be really affected by climate as well.

But is nitrous less affected by heat and humidity than NA or blower? I don't run in the summer because my times are ~.3 to .5 slower, which takes the fun out of it for me here in S. Florida...

 

I am now budgeting for a new rear end. Any suggestions on a specific r.e. ? And i wa thinking of maybe going the tirbo route,(though prolly not) what kind of $$ am i looking at if i go 1 turbo and are there weekly payments? I don't know, but i believe i'll go the supercharged route.
Thanks again all,
Chris
By the way, anybody have stuff for sale that would go on a 98 T.A.? im intersted in tires, chip, interior, and anything else that will make it go faster without alot of work. PM or leave a post.

 

Nitrous is less affected by weather.

 

Thanks Ed. Time to run in the summer?!

 

These cars don't use a chip anymore, now you have to tune the entire computer (hp tuners, ls1 edit). If you are looking for parts for sale, check that section of the site or put up a post on parts that you want. As far as weekly payments, what do you mean by that? Rearends, Ford 9", strange, and Moser 12bolt.

 

Thanks for the suggestion. I was talking to my friend not to long ago about alcohol injection, and was wondering if that went along with a turbo. I don't know honestly and was wondering.

 

If I wasn't such a cheap SOB Id go with the STS turbo set-up, you can set up with a methanol injection, bigger turbo than the base system and push 15 PSI without the typical lag of a front mounted turbo. For about 5K$ -Very Cool. but because I am the afore-mentioned cheap SOB. I will be spraying.

 

my personel opinion is buy a big cube motor (402 or 408 because they are cheaper, or if you want to go all out, 427 but that is like 4000 more) set it up at like 11:1 ratio which should be good for about 500-550 hp, then when you have the money throw a N2O kit on it. thats what i want to do. but as i said that is just my .02

 

Your asking $500-$850 vs $3500-$7000.
You make the call. Plus a stock bottom end can only handle so much. I dont like blue smoke in my emissions.

 

This actualy isnt that bad of an idea at all, a forged s/b runs about 3-4k these days but then you need heads.

 

I was in the same dilema and decided on the ATI kit until I forge the bottom end and run both the nitrous and ATI.

 

i am having a problem deciding to go and get a supercharger or just a quick fix nitrious kit...the place i was talking to about the blower wanted 5k for blower and installl...it was a v-1 sq i think..not too sure...but i am thinkin i will be getting about 125-160 added hp depeding on setup and spend 5 grand....then have to worry about my motot..b/c i would have it ona stock motor.... or spend 3 hundred and get a NX kit from my friend...and still have to worry but not as much....so i think im goonnaa go with the kit.....what u guys think is a safe amount to spray..i was thinkin about 100 and getting a window switvh and spraying through 2500-5000rpms...what u think
