Looking for power on a budget... Nitrous???

[Chris_32212]

thanks for the tip on the wet system. i will look into. as far as the 415 conversion goes.. in my opinion its a waste of money. im sure its nice but for the price of the car + that conversion, 30k + 30k i could have a complete Ultima kit minus the motor (which i already have). another 30k would get the car delivered in rolling chassis form minus the motor. and like i said, it would dominate everything under the sun thats street leagal with 4 wheels at the auto x track. its even faster then the bullet bikes, not sure how it would fair against some of the highly midified bikes though but im guessing it would be close.

You do a stroker ZR-1 because you are insane and love the car. Nothing else. It is a disease/sickness that has no cure. People who do it never question themselves about doing. They forge ahead and never look back.

buy one already done with the stroker, you will be money ahead.

i can understand that, i hope nobody is questioning my loyalty or passion for the ZR-1. i LOVE this car and its heritage and its legacy with all the records that it set especially the 24hour endurance record that it held for 12 years. but it has its limits no matter how much power you put in it, no matter how much money you throw into it.

buying a Z with a 415cid is a good idea. i actually looked at that idea when i was shopping for mine last year, problem was that i only remember seeing a couple of those cars for sale and they were listed at twice what i paid for my Z. i specifically remember one that was for sale for more then 40k and i bought my 93 for 19k. it would have been cheaper then buying mine and making that conversion but 40k was more than i was willing to spend on this car for the same reasons i have already listed.

When I looked at your mods, I didn't see porting the IH's and plenuum. That is relatively cheap and goes with the standard model of air in, air out. You have the air out but limit the air in. Normally a Z with your mods plus the IH's and plenuum ported will get around 400 rwhp. To bring that to the 600 rwhp you mentioned, you would have to spray 200 - 225 shot. It can be done but you are taking a risk as it does put a strain on the engine. If you are careful, have a window switch, get a chip tuned and limit how often you use the spray, then the Z does come alive on the juice. Be careful though, it is addictive having that much power, even for short periods of time. Next, you want slicks and skinnies and things start breaking. Your goal of cheap power starts to fall apart about the same time as the clutch, trans, rearend, half-shafts and spindles.

i will look into having the intake porting done but i recall it being rather expensive for a minimal gain on my 93 with the better flowing IH then the previous 375hp LT5's.

Not talking about the heads, just the IH's and plenuum. Should be less than $1000.00 and you should gain rwhp. Have you had your Z on a Dyno? Like I said, with your mods and with the porting on the intake side you should be at around 400 rwhp SAE. I can feel that you are asking yourself, how much hp gain. It depends on what you have now and how restricted your air intake is now. Since you have a '93 you might even be above 400 as your heads will flow a little better than the older heads. Porting the heads is expensive. I did not port my heads on my '91 and it ran pretty good on the street, strip and track.

i appreciate the info curtis. no dyno testing yet. i will look into porting for the intake a little more. thanks again. really any power adding suggestions (that aren't cost prohibitive) are welcome.

Curtis, no difference between the 90 and 93 heads as they are all Birmal castings.

He should be in the 400 rwhp ballpark with headers, porting and tune. But elevation will knock him down to the 390 or less range.

i'm a naturally asperated guy all the way, so i'll stay out of this. people think i don't like power adder combos at all, & that's not really the case. i don't do naturally asperated stuff because it's easy...i do it because it's hard. adding 10LBS. of boost or whatever doesn't really present much of a challenge for me, personaly. on the flip side if everyone was doing the same as me...well the world would be a boring place. for me...nat. aspr. stuff is intellectual intercourse, what can i say, it does it for me. do whatever your comfortable with Chris & we'll support you any way we can. have you looked into that rear mount turbo deal the boys are doing? they have it R&Ded. should be a slick deal.
