well I finally came 2 my senses and realized im broke lol j/k

I have a 1986 Iroc z with a 305 TPI and a 700r4, all im lookin to do is eat up ricers around here, im not tryin to bulid the fastest camaro ever just enough 2 get me by. I am kinda aiming 4 more torque than hp becuz I love the feelin of a hard take off throwin ya in a seat.

I want to keep my stock 305 and 700r4, and dont want to spend to much, and I want to keep the TPI system, I was thinking about a new T/B and bigger fuel injectors, 2 start with? hows this sound, maybe a new cam?

I want my ride to be very able to drive everday and not worry about it breakin down on me. im shotin 4 350 hp and 400 ft lb's torque?? does this sound reasonable 4 a 305 with stock internals???

any info whould be apprecited, thank you very much

To be real honest with you, the TB & injectors aren't going to help you very much with that "seat of the pants" feel you're looking for - in fact, they could even hurt you, unless you were to change your ECM programming to reflect the changes. (I'm guessing that your car is essentially stock.)

If you've not been by there yet, check out thirdgen.org's tech section - there's a LOT of stuff there to answer just about any question you might have, & a lot of people there who can answer the ones that aren't covered in the articles!

Here's an example of what I'm talking about. (One guy's suggestions regarding the best way to start modding a TPI car - YMMV though, as a lot of people think that the airfoil & pulleys aren't necessarily worth what they cost...)

Good luck!

 

to get 350 hp outta a 305 your gonna need to revamp the whole motor. however you could get like 300 ouitta it and make a fun street car.

do some minor mods, and definately 3.73's, posi, and a stall converter will make the thing launch alot better.

 

If you dont tear down your engine, your not going to hit 350hp and 400lb's w/ a tpi 305. Simply put Get a different TB such as a stealth ram or super ram, etc, and you will be under way. But your not going to get a pulley swap and bigger injectors and call it a day.
In fact, like another poster said larger fuel injectors will probably hurt you if your stock, and will deffinenlty hurt you if your stock with the stock pcm.

ok maybe I came on a little strong with the 350 hp 400 ft lbs torque, u think 300 hp will cream your average ricer?? I read a big article on the tpi systems and the big mouth intake with big mouth runners seemed to be the best combinations?? is this true??

 

Cam, Headers, Cold air kit, TB, fuel pump and NITROUS? does this sound like something you want? it will get you the HP you want much cheaper than any other way.i wouldnt be surprised if a 100 NX shot puts you right around 250-290 RWHP.

 

Good luck getting 400 lb/ft of torque out of the 305 on stock displacement naturally aspirated. I really doubt that engine is capable of that kind of volumetric efficiency, and if you did get that much torque out of it, it would be way too expensive to justify.

 

All the previous posters made excellent points. Getting that kind of horsepower out of a 305 is difficult to begin with. Doing it with everything kept basically stock is impossible (without spraying).

My suggestion is go with a Holley StealthRam. I read a recent article (I forget the publication) but it compared all of the aftermarket TPI options, and the HSR came out (generally) on top. It will generate far more horsepower, keep basically the same torque (though push the powerband higher) and you will not lose driveability. This setup combined with decent gears (anything bigger then 3.42 is unwise on a stock TPI intake, but with the HSR and that TH700R4, 3.73's would be perfect. 4.10's if you do mostly street driving), a decent stall converter (2500-2800 should be about right), and some of the common bolt ons should put you about where you'd want.

With gears and a stall converter, you're going to have real solid launchs (to make up for the shift up in the torque curve with the HSR), and then with an aftermarket intake, you'll be able to continue pulling up top where the stock TPI falls down. This would be the best bang for your buck, as I see it. If you decided to go with heads, cam, etc you'd be better off just building a 350 as many others have stated. With just the HSR/Gears/Stall/Exhaust, you should be able to dominate the local import scene (save for the big dogs), without much trouble. Good luck!

 

300hp in a relatively light car against 100hp in a pos honduh?
It's back to kindergarten folks

 

For acceleration definitely go with a stall converter, gears, and nitrous.

 

Maybe "honduh"s are different wherever you're from. Here, there's plenty of respectable "rice" rolling around. Actually there's more stupidfast imports then muscle. EVO's and STi's are everywhere, and that's just the bottom tier of the tuner crowd. Sure there are plenty of slow imports, but there's more then enough snappy ones to make up for it.

 

Whoa.. I dont know where YOUR from, but I have raced two honduhs in my FULL SIZED BRONCO alone (and yes, I have won all 4 of the races; 2 against each honduh) so i wouldnt consider them fast

 

There are 10-12 second imports running around all over the place up here. We've got a lot of the typical, slow nastily-riced hondas too... but we've got two shops locally that specialize in JDM motors and turbo swaps. There's some really impressive stuff coming out of there. They just finished an SBC supra and an SBC RX-7. There's some vicious rice running around. Those cars are lightweight, so it doesn't take a hell of a lot of horsepower to make them end just about anything here. The only thing I've got to offer against most of 'em is a decent launch---and that's only against the non AWD ones. Having an EVO stutterbox launch next to you with a fully built motor, big turbo, and lots of boost will definately change your opinion on "pos rice".

 

Yup gotta give em respect, Hate to but gotta. If i had a 305 i wouldnt be ashamed to lose to a gsr teg. It just the way it goes. But there is alot of slow d16's rolling around which you could most likly smoke right now in your parents caravan. If it has a turbo pretty much ...dont race it with a 305 or at least not a stock 305. These "ricers" are laying down 190 hp or more stock then they throw a turbo and spray and they get up into 300hp realy quik. I have a neighbor with a 12 sec VW golf!! Its insane but impressive. He raced my buddys 900 rocket from a roll and took him up to 120. The golf ran 12s the bike ran 11's pretty insane!! exspecialy without nitrous.

 

Yeah, this man knows. The "base" kit these two shops make, produce 220 whp on a 1.6 liter civic. I'd like to say that they break after the first summer, but they've been running around doing terrible things to us muscle car guys. When they get the quaiffe limited slip diff in the front and put some nitto/yoko's up there, the damn things hook well at the light too.
