If your running a stock motor with all the bolt ons with the stock injectors with a new pump etc.. is 330whp out of the question if your running like 13psi etc on the stock twins with a good tune??

sorry just cant search right now dont have much time so ill post and check back in a ahour or so.. gotta get ready for the klitchko peters fight tonight!!

 

whats your list of bolt ons?

i wouldnt run more then stock boost through the stock intercooler. too risky, been down that road, stock motor goes pop

 

your fuel system is going to be the bottleneck as well as the stock I/C.

we need more specific list of your mods as "all the mods" dont count for a lot

 

Google sport compact car web rx-7 project car. 350 wHP IIRC. Bolt-ons (including intercooler), fuel management to keep from popping the motor, little bit of boost increase.

 

i ran 14lbs on my stock injectors back in the day, injector duty was pretty high though, upwards of 90%
had to upgrade the pump to do it

 

power fc and commander
greddy front mount 3 row with elbow and bov
3" full stainless exhaust to a carbon ti catback no cat just midpipe
greddy profec b boost controller
greddy racing suction intake system for twins
HKS twin power and 8mm magnacore wires
koyo radiator and aluminum AST

hows that for starters? i mean pretty much all the bolt ons that are out there for running the stock twins. im just wondering with this stuff can you hit 330whp at 13psi or do you need to push the twins more? and if the injectors will handle that much.. im really going to get the most out of the stock injectors while keeping it reliable..

 

Yes.... with an LS1...

NO way I would do that on stock engine management. With the PowerFC and water/alcohol injection, full exhaust, etc... I would think it could work out. I wouldn't expect it to be safe with the stock twins for very long.

 

LS1 = Loser Swap Number 1

Jk, my friend has an LS2 and I'm amazed by it and would love an LS2 FD, but I like my rotary.

I think 330 would be doable, but why not just get BNR Stage 2s or go single turbo if you already have all the bolt ons?

I also, think you should definitely upgrade your fuel system just to give you more leeway. There's nothing better than a secure Rotary right?

 

Though it can be done, but i would not risk it. You basically have everything there. Just upgrade your fuel pump, get bigger injectors and a good tune and you're set!

I was able to hit 330whp with boltons and upgraded fuel system. (850cc primaries & 1300cc secondaries)

 

Stock 2002 LS1 with headers = about 325whp...

I was just going off of the thread title. A stock TT rotary is like 225whp.

Obviously the thread deviated to a full "bolt ons" FD with stock - whatever...

First rule of modifying a rotary... Keep it cool! (ie. water injection, cooling mods, elimination of the precat)

Second rule... UPGRADE the FUEL SYSTEM!

Don't be cheap...it will only be more expensive later. If you are dumping $3k into all the bolt ons, put another $700 in and get a pump and some bigger secondaries.

 

That's pretty mush the same set-up as me. I made 300hp on a dynapack which read low (i've been told around 10% actually). But it's definetly fun though. I'm upgrading fuel system now so i don't have to puch my injectors so much but it's doable.

 

yeah already have a denso 255 fuel pump installed and a new filter.. just didnt want to mess with the injectors if i didnt have too at that power level. i mean if i have too i can toss in some 1300cc secondarys but if i dont need to why bother..

 

This is a basic calculator, but you can get a good idea from it.

IMO, you are setting yourself up to hate your car... Why? You are shooting for a "number" rather than just enjoying the car. I've been on this forum for quite a while. I've seen people who were perfectly happy with their car; they take it to a dyno and the car doesn't put up the numbers 'they expected'; now all of a sudden they hate their car and nothing has changed except for the dyno.

IMO, put some mods on the car and just enjoy it. Don't shoot for numbers that don't really matter. The people who truly enjoy their car, probably cannot tell you 'exactly' how much power their car makes.

 

That is sooo true.

if you're planning on trying to push the stock injectors as far as they will go, i would rewire the fuel pump. It's really easy and will add alot more fuel from the pump.

A pfc or other ems is required for the power your looking for, as is an upgraded intercooler and a good tune on higher boost. Those are the really important ones. Other then that the mods you listed should get you to 330. I think the stock injectors will supply enough fuel for this but at a bit higher duty cycles then what most people prefer. The larger pump and rewire will help keep the excessive duty cycles as low as possible under the circumstances.

 

yeah im just figuring 330whp is going to be plenty of power for what im going for.. just a fun street car with minimal racing except the occasional mustang that pulls next to ya.. win some ya lose some. anywho thats why i was like ill just throw a stock motor in it.. and 2-3 years later get it rebuilt and ported when i have more money and then go for more power.. till then since i havent driven anything other than a stock fd this should be a huge wow factor for me to begin with and get used too before going further.

 

I agree with Mahjik about just enjoying the car. Granted I don't own a FD, but everyone asks me if my FB is a fast car (yoopers *shakes head*). I'm honost about it:it's by no means a fast car, but every time I drive it, I have a stoopid grin plastered on my face. It's about enjoying your car, not a "whose johnson is bigger" contest.

 

+100 for captain links

 

nice.
reminds me of my FC
(not the shooting for numbers part...)

 

I had 315whp with CAI, IC, DP, CB and M2 ECU at 13psi and stock fuel system

Im sure with a midpipe and well tuned PFC you can hit 330 but you might need a stronger pump as I was losing pressure up top
