ok well i got my 87 running and now im looking to get my car up the in the hp.so im woundering what all i can do and i want to drag the car and drift it and still take it to the streets for racing out there too.so any ideas just let me know.thnx.

 

If you want to be good at drag racing it will really suck at drifting, and if its set up as a drift car it wont hurt dragging as much as a drag-specific car would hurt drifting, but it still will not be optimal.

To set it up to drift you need to work on the chassis, get new wheels and rubber, and to set it up to drag you need to do it in the "other direction" of chassis tuning.

As far as the engine and turbos go, it depends on what kind of powerband and how much power you want.

Pick something and be specific or nobody can really help you except the sort of mods and "duh" things that everyone can do, like DTSS bushings, better tires, better brakes, BLEED the brakes, new exhaust, CAI, etc.

 

well, for drag and drift on a N/A engine, the best way to increase hp is to rebuild and port the engine(bridge port or a 1/2 bridge, etc). after that, make sure you upgrade your fuel system, and find a good way to manage it. perhaps an e-manage. get a good exhaust system(racing beat), and maintain the car. that should give you a good start.

 

turbo or non turbo, how much HP are you looking for 200whp, 250whp, 350whp, 650whp? 1200whp?

 

well im looking foraround 500 to 600 hp.and me and my friend want to really streetrace and drift it but i do agree with the porting and the e-manigement sys.but were looking at a stage 3 turbo system and and a streetport for the car.so do you think we should stick with the n/a or the 13b turbo

 

sorry but...... HAHAHA...... phew. 600hp is gonna be pretty tough, when I say pretty I mean... good luck. Look to spend a lot of $ and time getting it to that.

Id look for something more realistic like 400whp. Which with a large turbo and stand alone (with supposting mods) will make it pretty much one or the other.

With a large turbo your gonna be spooling pretty high and not make much hp down low which Im guessing would hurt drifting. Youll have a good drag car but only a fair, if that, drift car...

 

Get an LS1 the end.

 

is it a t2 or n/a

 

another dreamer

500 HP is not gonna happen, hell I doubt its even in your ball park to afford 250 HP... if it was you wouldn't be thinking of trying to make a non turbo motor do that... instead you'd be spending that $10-15K on a different car.

 

never going to happen that way, find a good shop and cut a check for 10k if you want 500+hp.

 

lol
if you look on ebay right now theres a fd thats making 603hp and its for sale for 28thou it seems that the low 200s are going to be more reasonable for you...unless you have a mountain of cash..

 

ok i over exagerated with the hp so how about 400 and what all do i need to do to get that.and why would it be hard with a n/a motor?

 

Even 400hp on an n/a is still pretty outrageous and out there... for an n/a engine id stick with a reasonable expectation of maybe 250-275hp. why is it hard? cause your just not gonna get those kind of numbers out of such a small engine. Even with a very agressive port job, and full out fuel system, ignition system and stand alone... and a good exhaust and intake, you still probably would have a max of about 300hp realisticly, and thats still pushing it imo

now 400hp on a tII engine isnt as hard. still a bit costly. youd need a stand alone ecu, fuel system upgrades, ignition stuff, large turbo, port is helpful but not a must. also exhaust and some other junk. so even going turbo, reaching 400hp is tough and costly. be looking to spend at least $6-7k to swap a tII engine and get it to 400hp

some of the highest hp street driven rx7's ive seen have been in the 550-600hp range. and they arent cheap to build or tune. so if you want those kind of numbers, like someone said, youd be better off either selling your rx7 or doing a v8 swap into it

 

400 HP on a stock trim Turbo motor is not easy or cheap...

400 on a non turbo is like asking for 400 HP on a 1.6 litre Honda motor. It is neither cheap, easy or at all reliable

 

ok well so how bout if i swap the 13b for a 13b-tt or the 13b-t?becasue were looking to get some good hp out of the car.and can yall please tell me were the fuel injectors are because im very new to the rx7's

 

13bt and 13btt will get you pretty much the same hp numbers, cause if you got the tt youd end up replacing them with a single large turbo anyway. it depends on what your looking to spend but the everage person with the "average" build sees anywhere from 250-350hp out of a turbo 13b. some see more with better tuning and larger turbo and more boost.

The "average" build is ussualy:

-Upgraded turbo ($500-$1500)
-Exhaust ($500-$1000)
-FMIC ($250-$1000)
-ECU upgrade ($250-$1200)
-Injectors ($250-$500)
-Sometimes a port job, which requires a rebuild ($1200-$2000) if you do it yourself
-Any other bolt ons or tuning equipt. they feel needed ($500+)

So if your planning on dropping a 13BT into your FC and getting 300HP+, be looking to spend anywhere from $4000-$6000+

the injectors are under the upper intake manifold. it has to be removed to get to them

 

If you can not just look and see where the injectors are, then a engine swap may be past your abilities.

Furthermore, you do know that the only reason to get to the injectors is to replace a bad or leaking one. On a non turbo motor the injectors can support up to around 225 HP, which is considerbly more than the stock trim motor will produce. Changing out the injectors to bigger ones will result in reduced power and fuel economy and increased emissions. The stock non turbo already runs way rich for most of its power band, and bigger injectors or fuel pump will just make that worse.

Unless there are major changes to the porting and flow of the motor and you have either a Standalone ECU or at very least a SAFCII or simular controller no changes to the fuel system (including the fuel pump and injectors) should ever be done and even then only with the understanding of what you are doing.

 

Okay, before you go any further you have to re-evaluate your goals. Instead of thinking "I want 400 HP," think of what 400 HP means to this car. Look in the time slips and dyno forum to see what people are doing with what results. Consider what you're going to do about handling because either you want your car to be a jack of all trades or you don't know what you want. Read more, learn more, then choose. Hell, I've had my car since February and I still don't know what I want to do, really.

With this in mind, realistically re-evaluate your goals and your budget.

 

Thats pretty good advice. Plan your goal around what you want to run in the 1/4 mile. 400hp in an fc is pretty mean. You might be happy with 300hp. I know I will be as soon as I get my income straight again.

 

ok well i will take the advice and the car has been sitting in a guys yard for a while so thats why i wanted to check the fuel injectors.
