ok guys and gals now that i have a stronger tranny and a strong rear end (for now i hope) i want to try to get some more HP out of the motor. i was thinking about getting a set of bare heads get them cleaned out new valves lt4 springs and lt4 cam. is that a good idea to do? are there any other options for me? all i am trying to do is get as close to 300 hp and at least 12's in the 1/4. i am more a road racer / auto x/ drifting kind of guy. (i don't live 1/4 at a time [ i know shameless fast and the furious plug])..lol let me know what you guys think

 

you don't have to pull the heads for 12's... just do the lt4 hot cam kit with some 1.6 rr's, headers, a tune, timing chain and some other stuff...

it's hard to tell without knowing anything about your car...

 

lol well the car is an 88 mazda rx7 with an lt1 in it. i have headers and a full exhaust. i am close to my goal of 12 but i need to shave off a second more. i am not sure what else to do to it i just know i want to see 300 hp on the dyno

 

You might consider a CAI too.

 

Full bolt-ons should get you there, full exhaust, cold air intake, PCM tune, 1.6 roller rockers, and an electric water pump.

 

e water pump didn't think that would do anything. so your saying roller rockets without changing the springs? man i didn't think it was going to be that easy to get to 300 hp to the floor i have an intake the full metal one no plastic arm. hmm so with a 500 to 600 buck budget i can gain 40 or so hp!

 

Are you sure that motor is healthy? I have a setup very similar to yours and run pretty consistant bottom 12's on motor. Whats your trap speed?

 

last i ran i didn't do so good 2.10. but i am hoping my new tranny would help me out there! the motor doesn't have many miles i think it says 1600 on the speedo

 

An electric water pump has been noted to give gains of almost 10hp at the wheels. And no, if you do roller rockers, you should change the springs as well. With your budget, it will be very tough to do all of those mods.

 

2.10 60ft?
What was the MPH?

 

What kind of tires were you running on?

 

215 55 16 is the tire size they are michelins, my mph i am going to have to look at my time sheet for it, your asking about the trap speed mph right?

 

Put on some drag radials and watch those sixty foot times go down.

 

yeah once i get that t56 in tomorrow i will get it all buttoned up and make sure all works well that is going to be the next thing i get. but i was looking for some stock heads to get cleaned out and new valves and get the lt4 cam setup i think i am going to be happy with that then when i get greedy next year go with some boost

 

You might even want to consider one of the basic setups from Lloyd: www.eportworks.com He can work your stock heads so they make some nice gains and can set you up with a cam as well.
