So I haven't been on the forum alot lately--- the whole life thing is doing me good. I'm getting married and got a new much much better paying job. Its time to payoff some debt and get the car back up and going with a couple mods to reach a realistic goal.

The Goal: 205 HP 1990 NA

Current Mods:

• Basic DYI stuff.
• Removed Rats Nest & Air Pump
• Removed A/C equipment and pump.
• Removed P/S pump.
• True Dual Exaust, RB Race header,(dual 2.25" pipes all the way back, two resonators and 2 flowmaster 40s). Loud, but reasonably so. Doesn't hurt.
• Reworked electric 6ports and VDI. Using stock ECU for trigger times, Electric air pump for activation. *They do work properly!!*
• Removed clutchfan (it was locked) and replaced with efan.
  *NOTE: the clutch fan will either be reinstalled or a better efan installed during rebuild.*

Non Power-Related Mods:

• Automatic -> Manual Conversion
• OEM/Stock FW, Clutch, and PP (Disc probably needs to be replaced)
• 390 -> 410 Dif Swap
• KYB Shocks, Intrax Drop Springs
• Wheels and rubber
• RE Spoiler (needs repainted though).

To be done: Non-inclusive to budget stated below...

• Project84 is currently helping me with the rebuild.
• Front plate has coolant passage broken. Replacing plate.
• Standard rebuild including new side seals, apex, and springs
• New rotor bearings
• New Stationary Gear bearings.
• New counterweights.
• Injector Cleaning (OEM Injector sizes)
• CAI -- just for the hell of it, its been thoughtout, just never took the time to implement.

What Needs to be done to reach 205HP?

• Budget < $1000 (excluding rebuild parts-- already ordered).
• Would prefer to keep stock ECU/fuel-comp
• Supercharge and Turbos are basicaly out of the question for right now.
• Porting is a possibility, but can't afford to purchase ECU to control the engine after porting-- must rely on stock ECU currently.

Alright, so give me your ideas!

• Realistic goal for N/A without massive porting?
• Realistic goal for budget considering current mods?
• Realistic goal considering stock ECU restriction.

EDITS

• No NOS!

talk to kahren. I beleive he is around 200-205 with his NA

if you want that kind of power you're going to need some sort of fuel managment. Even if it's just an safc or something equivalent. and you are going to need porting .. really good porting

Tokyo-RX7

Some nice porting, ported everything... and IDA throttle body kit i would definately recommend after market flywheel too, a lot of HP is lost within the drivetrain. Im looking to make 200HP too, but im kinda goin a different setup.

If you want to make nice power, I suggest you look no further to having Kahren do you're porting. His stage 2 streetport will land you most likely higher than that HP goal.

Tokyo-RX7

does this Kahren have his own shop or website? i wanna see some work. i might be interested...

silly

wow... your shifter looks SUPER short

Tokyo-RX7

i have that same air freshner in mine too. haha yeah that shifter is hott man, what kind is it? is it still easy to shift. i want it

no. kahren is an enygma. he exists. but its like... hes super rarely seen. go look in the dynocharts or just search fir threads posted or started by him. lets just say he is very veru capable of making your engine go ZOOM ZOOM!!

RETed

Are we talking about 205 at the wheels?
I doubt this is possible.


I doubt this is possible.


Too bad.


Porting really has nothing to do with the stock ECU.
A ported motor would run on the stock ECU no problem.


With the stock intake manifolds, 190 at the wheels is doable.


Basically, under 200 is realistic.


Still the same.


You need to realize that the stock intake manifolds end up being a major restriction.
If you want 200+ hp out of a 13B NA, you need to redo the intake manifolds.
Now, if you just trying to shoot for a peak HP number, it all becomes a sacrafice.
High end power requires short intake paths - faster the air gets into the engine, the better for "breathing".
Long intake paths increase intake velocity, which aids in low RPM power.
The stock intake manifolds are designed for a compromise, but there is emphasis on low RPM power.
To run big power on a 13B NA, we're talking ITB's, but this hurts low RPM power.
Can you live with a motor like this?

Full bridge port plus megasquirt and wideband O2 sensor. Thats at ~ $500 dollars
My vacuum 6 ports and possibly VDI if possible. Porting on the intake manifolds as well.
Then a tuning session should be less than $300 and that should be it

damn it beat me too it

Also huge street port along with the bridge port. High pressure fuel pump, and tunable ECU or Haltech.

or maybe just get a TII! lol

Hope it's not a daily driver if you bridgeport. Been there done that and quite frankly it becomes a real annoyance after awhile...Fuel consumption is gonna be 5-7mpg.

Kenteth

-- Daily Driver, well... sorta. I refuse to bridgeport at this time.
-- I figured 205 might not be realistic. I knew saying something like 220 is just retarded though.
-- I wasn't considering at the wheels either, I didn't figure that would easily be possible.

-- Thie shifter is homebrew. I've recieved alot of crticism about it, all I can say is you'ld have to drive it to actually understand it. Project84 gave me alot of **** about too until he drove it :P

And, see the attatchment for reason for rebuild.

what the hell happened to that housing?!

Honestly?

Talk to Kahren, buy 550cc secondaries and a safc, buy a FD fuel pump and get abetter clutch. Badda-bing, dyno proven 185-200HP or so (depending on the tune). It's the way the car is ported and tuned. Not so much the "size" of the port. Efficiency is king. But then again, not having scavanging may hurt your performance all around, so talk to Kahren before hand.

That's pretty much it. Or go with ITB or even a carb (if power is your only priority) .

You needed a better tuner and I hope you were running a fuel injection system.

I have to agree with *gasp* RETed. 205 to the wheels aint gonna happen with a stock ECU. 205 to the flywheel is not too hard if you can do your own porting and afford an SAFC. Add a full exhaust and there you go. 205 to the wheels is about 245 to the flywheel ..... stock renesis territory assuming it is a real renesis and not the ones Mazda actually produced, lol.

haltech, ITBs, Good header setup, some porting, and some tuning. DONE strip the engine as much as possible.

Hey pm me on where you got that daul pulley for the altenator.

I was assuming flywheel too.
