Hey guys I have a couple of things on my mind that need some answers.

First thing first.

I have a 1989 Iroc with a 350TPI engine that has over 100k miles. It has hooker headers and a high flow cat. The car also has some tranny work done to it. With street tires and an elevated racetrack of 2640ft the car was ran a 15.9 best time.

My question is how can I get that 15.9 to a low 12 high 11?

I have a budget of $2000 that I want to incorporate to this project. I am open to any suggestions and am really seeking help. I want to be able to beat a s/c cobra at the racetrack and that is my goal.


Thanks Guys!

 

Thats exactly what i'm shootin for, except my budget is $2000AUD, not USD, lol. I have pretty much the same car, so i think i'm goin to buy an engine rebuild kit (bearings, rings, pistons, gaskets, etc) from someone like Summit, and a set of aluminium heads and matching cam from Edelbrock. Do some weight stripping too, i think. I might rebuild the auto (with a B&Mshift kit) as well, and maybe put lower gears in the rearend (i currently have 2.77's)....

Does this give you any ideas?

 

Nitrous,fuel pump, gears, sticky tires, good tune up.

^^^^^2nd.

 

would this really get me into that high 11's zone?

HSR (Holley Stealth Ram) Rebuild the motor to support high horsepower and maybe a stroker kit and some nawwsss. You would be in the 12's for sure.Good luck

 

So these TPI engine arent at all bad huh? I was thinking of rebuilding it with the HSR or TPIS intakes and make the engine support a twin turbo kit like a month after the rebuild. Think with the twin turbos ( t3/t4) would it make it into the 11's?

 

With enough boost anything is possible, the question is of course money. For $2000 you're going to have a tough time building the engine to handle lots of boost, doing the twin-turbos, new intake, strengthening the trans, rear end, suspension so it will hook, etc. etc.

 

to get all that done how much do u think itll take? The 2000 was just a random number

 

Yeah nothing simple is going to get you into the 11's. And plenty more then $2000.00. I know people always have high hopes for their cars, but it takes alot of time. And alot of money to get things just right. Not only motor wise but the drive train to put the power to the ground....without breaking anything. You can build up your motor all you want....but if your tires are spinning,that means you need traction.
Its hard to tell you what to do because I have a friend with a 2003 mustang cobra, he upgraded his supercharger, pullies, and a nice 200 shot of nitrous and hes over 600 rwhp. So slightly modded cobras are pretty quick.

 

A forged rotating assembly is in the neighborhood of $1500. Unless you plan on removing it and putting it together yourself, figure in the cost of labor there, anywhere from $1500-$2000. Master Power turbos run about $600 a piece. You'll need manifolds fabbed, BOV and a wastegate, easily another $1000. Holly Stealth Ram will run you about $600 for everything you need, TPIS TPI will be about twice that. And that's just the engine.

For the money nitrous is going to be the way to go. And to run enough nitrous through your engine to get you into the 11s it's not going to last you very long I wouldn't think.

Unfortunately power aint cheap, especially when you want reliability on top of that. To give you an example, I'm in the process of having my engine redone. I've bought heads, an intake off Ebay, and that was almost $2000 right there. Luckily I can re-use my camshaft, but I still have to buy a rotating assembly ($1000 non-forged) and have the engine pulled, taken apart and rebuilt. I'm going to have about $5500 in it when it's all said and done, and I'll probably run high 12s, maybe mid 12s on a cool day with great traction. Oh, and everything I've stated assumes you have decent gears, headers, exhaust, stall converter, etc. which if you don't, you'll need.

 

I think I am going to build the engine to run psi but Im still wondering whether to go S/C or Turbo. I saw this yesterday on ebay and was thinking it would be ok

I have the tranny rebuilt with a something stall converter and a shift kit with corvette servo and hi perf clutches. I need gears and I have hooker 2055 headers. Think that would help me out to reach my goal? If not I might just get some sticky tires and run nos until engine blows and just rebuild it.

 

12.2's on junkyard stuff here. Spraying a 150 shot should get a TPI with headers, good exhaust, good tune up into the mid 12's. Walbro 255lph fuel pump, Port the base, heads, and install a cam you're looking at near 11's spraying on a stock bottom end that should last quite a while.

 

RUN FAR AWAY FROM THAT TURBO KIT! My friend got stuck with one of those SSAUTOCHROME piles of junk that we can't even sell now, it makes a nice paper weight. Look up there reviews online, they explode.

 

thanks guys i think i am gonna go with the nos,fuel pump, porting the tpi intake,runner,base, and getting some gears and heads. Thanks!

 

All well & good. But if you're intending to put all that on a 100k short block,
keep up posted on when you have to do it all over again...

 

I did all the stuff to my block with just over 100,000 miles. I'm now looking into getting some dart heads. Why not, if its not broke, then dont fix it. I did do a compression test though, and all my cylinders are still in great shape. But remember....all the bolt ons, can be removed. If I blow up the 305. I'll rebuild a 350, and put everything I have on that block.

 

your first step should be GEARS!!!!!!!!! NOTHING will move your car faster for cheaper. just ask any old school hot rodder. a more agressive gear ratio in the rear and you'll think you put a whole new engine in the car. second should be a cam. and a chip to make the computer cooperate.

 

Forget the chip, cookie cutter chips may be better then stock in certain cases, but at the same time nothing will beat what you can do with your own custom PROM.

 

any cam worth putting in will REQIURE a custom chip obviously. but ideally the best plan is to scrap the POS tpi setup(thats probably going to **** some people off.) but were talking about being on a budget here.
