Guest mikey_clark Posted August 3, 2003 Share Posted August 3, 2003 I've looked through a ton of the posts in this section and the V8 sections and I see where a lot of guys go for a V8 to get a fast and torquey car that's still very driveable. What I'm wondering is how much horsepower and torgue I could get and what I'd be seeing for 0-60 times if I build my z engine up so it's faster but still driveable for a novice (ie; my girlfriend) who very much wants to drive the car. Also I live near San Francisco and will want to take the car there reqularly and will need to be doing some steep uphill starts. I'm one of those guys that likes hearing a small engine rev but I also know I want something driveable. So chime in with those HP and 0-60 figures you'd expect for a driveable 240.

Guest dero Posted August 3, 2003 Share Posted August 3, 2003 with my mods a L series builder quoted me around 250hp Quote Link to comment Share on other sites More sharing options...
fl327 Posted August 3, 2003 Share Posted August 3, 2003 I drove a stock z in the hills of SF for years, no problems, just had to use the ebrake a little bit sometimes. I dont knwo 0-60mph I do know that stock z 1/4 time is like 16.8 and ive seen em at the track bust 17.1 or so. 250hp from an NA is pretty expensive, but very very fun.

Guest norm[T12SDSUD] Posted August 5, 2003 Share Posted August 5, 2003 Assuming you do not want spend a ton of money on engine swaps you could add a 3.7 rear end gear and stay with your 4 speed or drop in a five speed and a 3.9 or 4.11. The lower gears really pep up the Z's off line zip. Next you could put in dual K&N filters and a 2 1/2 exhaust. These mods were good for mid 6 sec 0-60 times and very low 15 second 1/4 mile times. If you still want a little more speed drop in a mild cam like a 262/272 Crane cam and add a header to your exhaust system. With the above items my old 240 was good for low 6 second 0-60 times and 9.4's in the 1/8 mile and mid 14 second 1/4 mile times. Later on I installed an N42 head which had been shaved .070" and had a 272/282 Crane cam onto the stock 2.4L block and the car ran 13.6 @ 99.1 mph in the 1/4 mile with low 5 second 0-60 times. Granted to get any of these times you have to be willing to drive the car HARD. If you drive it somewhat sanely you will need to add a full 1/2 second to all the above listed times. later Quote Link to comment Share on other sites More sharing options...
Guest mikey_clark Posted August 5, 2003 Share Posted August 5, 2003 Thanks for the info Norm. How easily driveable was the 240 after you put the cam in? Could my girlfriend who has very little stickshift experience drive it? I'm really leaning towards keeping the six as long as it doesn't need a total rebuild.

The small cam is not a problem, but the larger one requires a occasional blip at the lights or the plugs will load up and foul out. if I had an MSD unit that wouldn't be an issue though. if you aren't planning on racing the smaller cam is a better performing cam around town under 5000 rpm.

Guest norm[T12SDSUD] Posted August 5, 2003 Share Posted August 5, 2003 norm what should i expect with my mods? Depends on how ya drive it, but it looks to me as if you have potential to run low 13's with your setup. Get some slicks and high 12's should be possible. later Quote Link to comment Share on other sites More sharing options...

Guest Zcarsmakemyheadhurt Posted August 5, 2003 Share Posted August 5, 2003 When your looking for horsepower in a normally asperated engine cam and compresion can make you or break you. The bolt on's and tricks can free up some power but overall most mildly moded ricers will give you a run for your money. Gear it, headers, exhast and low restriction air filter assembly is first off on any engine that needs to breath to make power. Then the way to keep it drivable is by a powr adder i.e NOS, turbo, or a super charger. I like the Nos,it wont effect the daily issue and tuned correctly youll have a big burst of horsepower when you need it. The wear and abuse would be the same as a turbocharged or any engine makeing alot more power than it was desighned to, so don't sweat the "I don't want to hurt my motor" deal. Done right you will be OK and the little honey can also take part in the fun. Good luck Alex C Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted August 5, 2003 Share Posted August 5, 2003 Alex, WELL SAID Folks need to aware that they should not fear NOS, Turbos or S-Chargers. It is not the boost or NOS that kills engines, it is the detonation. Like everything else, there are limits to how far you can go and in these cases, the limit is when you reach the point of detonation. That limit can be extended by careful tuning, timing being most critical, high quality and the required quantity of high-octane gas and for the forced-induction, keeping heat to a minimum.
