i have an 88 rx7 GXL (non turbo), and i want to add horse to my car. I know it comes stock with around 145 HP, and i got a new exhaust system which put it up to about 160 HP. I'm pretty new to the car enthusiast world, and i am wondering what else i should do. I was thinking about a new intake and stuff. Any suggestions?

 

Intake with exhaust will make for a fun car. A tune-up would be a good idea aswell.

 

search for a thread called "how to make a beefy NA"

 

welcome to the world of the N/A. Almost no one is ever satisfied with their power .

And never will be... cause there isn't enough!!!!!!!!!

I'll never go back to NA

 

Naw... cause N/A's are FAR too reliable...

*tuning- the endless pursuit of the perfect explosion*

 

thanks. I got a new exhaust with new converters. And i want to get a new intake. Would that make it noticibaly faster??

 

You really want to ditch the cats if you can. At least go with just a high flow main cat. Then get a cone intake with some way of getting cold air to it(custom cold air intake, cold air box, etc). Maybe get an s-afc and get on a dyno. Can also advance the timing some to get gains, but ask around on how much to advance it to be safe. Oh, and weight reduction is your friend.

 

I have noticed the performance with our CAI.

God I can't wait till I have it back on and can do some more HIGH SPEED RUNS@!!!



To check our intake out just click on the picture below.

 

If it doesn't make it go, stop, or look good, take it out of your car. Losing 250 pounds is like gaining 50 horsepower. The difference in my car is unbelievable.

 

I tend to agree about loosing weight, i made a huge difference, and I like my n/a, I'd much rather have it then my roommate's tII, he seems to be fixing it for some reason or another every other week. But don't get me wrong there's alot to be said about a good turbo. but as far as the original question, yeah an intake is your next move if you've done the exhaust, it only mades sense, if you have alot going out you might as well have alot comming in

Hey Unsent, welcome to the board. You should come check out the Midwest forum sometime and come to one of our get-togethers. Where in St. Louis do you live?

 

Add a turbo....

 

haha TII's rock!

 

Can anyone say noobie. Strck RWHP is around 110-120 depending on how health the engine is. ALSO the 146 factory flywheel rating is with the FACTORY exhaust. Adding a higher flowing exhaust system will increase flywheel HP as well as Wheel HP.

 

Where did that quote come from 13bpower?

 

How the hell does an exhaust system only increase RWHP and not BHP? The only way to raise RWHP is to raise BHP

 

not technically. WAAAAAAAAYY better lubricants, lightened flywheel(i'm pretty sure) and things like that i.e. you get back power loss from friction

 

Better lubricants won't realistically net you hp, but they will prolong life. The only hp claims I've heard are Royal Purple and they get you about 2hp if you're lucky. If you want to add power, there's no sense screwing around with stuff like this, flywheels are icing on the cake stuff, you need to go at it at the root. Ie. turbo or a port job etc.

And what exactly would these "waaaaaaaay better" lubricants be?

 

Something alot better compared to the cheap generic shiet from 7-11 i see a lot of people putting in there cars. Basically what you said, Royal Purple. Two ponies is two poinies. And i know both of these are really icing on the cake and they won't give you much more hp to the rear wheels...i was just stating that it is possible

 

I don't think there's too many rotary owners that buy their oil from the 7-11 or K-Mart's in house formula.

 

there was a poll on this board earlier that stated otherwise...

 

ok there are lots of threads ont his so search, but basically heres how it goes:
1 exhaust
2 intake
3 weight reduction
4 internals...ie porting manifolds or engine
5 forced induction/ nos

the first three are realatively inexpensive and generally have no ill effects...better exhaust is extramely effective..guess u have that tho..go get cold air (or make it its not too hard)..if you are serious about it, remove all the extra **** from your car..ie power steering, ac, foam padding, maybe some electronics, spare tire (personally i think thats stupid, but if you want it does save weight) etc.
then comes the more expensive or complicated, although also more effective ****... porting your engine requires disassembly, but can net you lots of hp if done right, forced induction and nos are obvious, porting of intakes can get you 5-15 hp, but is kinda hard to do.

after that..use your imagination. its not hard to find ways to make your car faster. its generally not even hard to do it. basically it all comes down to how much time and $$$ u want to put into it.

but.. if you arent too crazy..the bright side is that i have about 4k total in my car (i do all my own work tho) and i would estimate 190 or so hp (maybe 170 to the wheels?) any more than that and ur talking some serious cash tho..or at least more than i have.

good luck
