i have a 2001 neon r/t so far i have put the srt exhaust, afx ecu, aftermaket intake mani, 60 mm tb, and cai put into it i am looking to pick up more horsepower and make my car faster and faster over time. im not much of a motor head i know enough to get by and my friends helps me with whatever i dont know, can anyone give me some ideas of what else i can do to gain more horsepower and speed? thanks

If you have an AFX you have the advantage of increased RPMS. My suggestion would be a larger cam such as the Crane 14 or even one of their larger cams, depending on what your goals are. This is if you aren't planning going turbo or something. You would probably be able to sell your magnum cam on this site. Some folks have had good luck replacing their magnum header with a long tube. That would also be a good idea for maximum power, although it will be louder and reduce your ground clearance. Look around at some of the people who have magnums and what they have done on this board.

ok cool thanks i will look into it ..but yea i not looking to go turbo if i where to i would just swap the srt-4 into it but for now i am just trying to max out the power but thanks! if you have any other ideas let me know and if anyone else has anything diffrent to share i would appreciate it thanks guys!

You already have a decent head, but you can get very good gains from porting/polishing/milling it.

What "aftermarket" intake manifold did you put on?

Get a long tube header....$227 to your door from TTI.

Yep, a header would be the next logical step. You've helped it breath on the intake side, now you need to help it get rid of the exhaust. Header, free flow cat(or cat delete if you'd don't have emmisions checks in your area) and a good muffler with a nice tip would be the easiest "next step". A Cam would really help all the other bolt on stuff come alive though. I like the Crane 12. Of course if you can find a Magnum head and have the cam put into it that'd be your best bet but I guess they're kind of hard to find. Since you've got to pull the head to install a cam I'd just rather go to the junk yard, get a good used head and have it fixed up, that way you can install the new head with the cam and springs in a weekend instead of having you're car down for a week or more while the head is being done.
Something else you might check into is an Under Drive pully, that'll free up a few HP right there and don't forget the motor mount /transaxle bushings. They'll help take care of wheel hop and help you transfer your power to the ground where it needs to be.
You'll be going faster so don't forget the brakes and anti-sway bars to help you stop and help keep you on the road when you take a corner.
It really just never ends. You mod one thing then two other things need to be modded to keep up with the first mod, but then that's part of the fun.

I put on an r/t ernie boxstyle intake manifold which was ported and polished ...and what header do you guys think is best someone mentioned to go to tti but what type long tube or short or mid? and what make do you guys feel is best thanks for all your guys help this is great

Crazy...i'd be interrested in some pics.

I have the stock plastic manifold. =\

The TTI header I suggested is a Long Tube Header. Yields the best gains...especially up high the car pulls hard it feels good.

under drive pulley or header would be next choice. then u could always get a ported head and cam too.

AMM

underdrive pulley would be good and there relatively cheap. Again depends on your goals. Nitrous is the biggest bang for you buck.

but how much stress does nitrous put on my car im not looking to kill my engine or anything and how easy is it to put i nitro kit on

You should be able to run a 50-75 shot on a stock engine that's in good shape without hurting anything. It's when you get to 100 or more that you have to start retarding the timing and going with a cooler plug and have the bottom end built up to take the extra pressure.

You suggsted the crane 14 cam do you know if i can use the magnum valve springs on this cam

Guys this is my friend and hes using a lot of the old parts i had on my r/t he doesnt want to go crazy cause it is his dd. Maybe a nice 14 to take advantage of the afx r. BTW that was once canuck 2k's ecu for his 2.2 magnum was a prototype from howell i personally hit over 8500 rpm and never hit the rev limiter.

zandifam · Post by **zandifam** » Sat Dec 08, 2007 9:57 am

I know the post is a bit old now but to answer your question, yes I believe you can run a 14 cam with your magnum springs. I probably have over 30000 miles with magnum springs with the comp 400 which has even more lift than the 14. Some others on here have used the 14 with magnums and can chime in. I believe the 14s peak horsepower is a bit higher than the 400s due to more duration. A few dyno graphs floating around suggests it peaks at around 7200 or so. Your able to take advantage of that with the AFX-R. some people have had problems with idle quality with the 14 which may be due to air fuel ratio at idle. for me the 400 is barely noticeable at idle.

white2000neon · Post by **white2000neon** » Sat Dec 08, 2007 9:48 pm

Yea we plan to pull some fuel with an SAFC at idle. I know the 400 has more lift than the 14 and lift causes more stress on the valvetrain, but I want to make sure it will be able to take 8k+ revs.

zandifam · Post by **zandifam** » Sun Dec 09, 2007 12:35 pm

My valve train is definitely noisier with the 400. It probably needed lash caps with it. But so far so good. others have used the 14 to past 7500 so you shouldn't have a problem. Cam is a great upgrade to magnum in my opinion.

Plastic is actually lighter and better/smoother flowing.

Yea I think the 14 will do good especially with the added RPM's, but will the magnum springs be able to take the extra revs (8k+) with a cam that has a little more lift and more duration without getting any float and smack pistons.
