haltech on n/a...
pretty simple subject...is anyone on here actually running a haltech on their n/a?what kind of results?i would love to stick one of'em in my rex,but for 1300 bucks,i guess i would like to see some results[and,no,lets not turn this into another turbo vs n/a discussion].would love to see any results from any setup,but,hell,if it was close to mine,would be even better.[check my sig].and,what is everyones oppinion...i used to think it was a waste of money,but the more i look at it,the more it makes sense[i know,i'm trying to talk myself into it],but,ad up the cost of running a safc and having to replace a few aging stock sensors[as i might],mazda seems to think they are made of gold,you start getting pretty close to the cost of a haltech[well,give or take],heaven forbid your 15 year old wiring harness starts to give you problems,etc.and the damm 3800rpm stumble...

IMHO, I think you can gain some power with a Haltech, but not $1300 worth of power - you're at the point of diminishing returns. Seriously, I only think you're looking at a few horsepower out of a Haltech - not worth it, and not worth the pain in the *** the Haltech is to install and tune.
Get a Super-AFC and have some fun. Spend the $1300 on some Tein coilovers and have *lots* of fun .
NA's are quick and fun to drive, but they're never going to be mega-horsepower monsters.

good point...but,a s-afc,$320[or so]and 1 tps[wich, i belive is causing my hesitation]$180.-,i'm allready at $500.-.of course i would have to dyno tune a haltech,but,to really use the s-afc right,i would wanna tune it on a dyno as well.and,in a evil kind of way,ripping out all that crudy wiring sounds like fun..
any1 else?

Get a haltec. Why? because everyone who telz you not to doesent have one nor have seen the results from one. If eliminating the maff sensor and customizing timing , fuel and VDI actuation points doesent give you more than a few horses than what a waste. But Thier is big gains here and you shouldnt listen to anyone. If It was about HP ratings and or 1/4 mile than we would all buy V8s and Turbo miatas for not much money at all. But the point is to get YOUR car as fast as it can be. Why not go the extra mile and finish it with a haltec and sqeeze every little bit of hp out of it , because thats the point , Not just 1/4 mile per $ ratio. So far on my 89GXL I have ported manifolds to engine, TB mod , AFC, Custom intake , exaust , underpulleys , efan , weight reduction , clutch , Drag radials exc exc. My goal is to make a fast N/A for an N/A not compared to anything else. Happy rotoring.

von-glad to hear someone with a positive aditude about this.... essentialy,thats what i'm trying to find out here..what are the gains with a haltech,power wise.we all know t2 are fast,when modded.
i stopped by mariah motorsport,when i was in santa barbara a couple of years ago,i spoke to one of the guys in there,they where running a stand alone on their n/a racecar.unfortunately,i dont remeber what it was,wolf or microtech,i belive.they where running some pretty good hp #'s.its been a while,so i cant exactely remeber what he told me,but i was 220+[at the flywheel].anyway.figuered i would give this thread some more exposure time.
hailers-another good point.i actually have a spare set of injectors,i'm gonna send'em in and have'em rebuilt.that way,i can get them installed w/o any down time.plus,i think i'm gonna get some pineapple racing sleves and install them when i replace the primaries.

Where do you get $1300 from? You can get an E6K here for $1155:

And yes, it IS worth it IMO. Not only does your engine run better, but you also get AFR readings, barometric readings (senses intake restrictions and ram air effect), inlet air temp readings (senses effectiveness of cold air induction), datalogging, thermofan control, turbo timer (yes, it works with an NA too), rev limiter, and shiftlight output.

IMHO, it isnt really worth it on a N/A. Most of the turbo guys use it because theyre at their stock ECU's limits, not to squeeze extra HP. Or putting a motor into a car that requires some form of fuel control. I think you should get a distribustor, and a carb. Alot easier than a engine management system. Itll make you engine bay nice and empty too, with hardly any engine harness needed.

I'm going to say if you're willing to spend, go for it. It's all about what you want to do.
And I was going to bring up Evil Aviator's point as well (we've probably seen the same cars, I know Scott's is one). I've ridden in that N/A many times, it's only mods were some aftermarket mufflers, an intake, weight reduction (a lot!), and a Wolf EMS. It was one hell of a ride. It beats stock TIIs, and that's almost a second difference. With plenty of other mods, you could make good solid power out of an N/A.
Also, as previously said, those who tell you not to, probably haven't seen what results it can bring. It just seems like it would be a waste of time, but it's not.

BTW, I drove Scott's around the parking lot in all 5 gears without ever putting my foot on the gas. Try that with your stock ECU!

If your going to get the E6K I kind of suggest you wait a little bit for the newer version to come out. I expect the price on the E6K to drop, unless they raised the hell out of the price for the newer one(E11?).

Ah, you want the fully terminated harness and 1Bar MAP sensor. Yeah, that's $1306 at the link I posted. OK, I see now.

I say buy it... You will be able to run higer rpm and take advantage of your S5 rotating parts and your port... Not to mention it will be fun to tune it, and you will reeeealllllyy get to know your car. Any future mods you can optimize the tuning and know you are getting the most out of you engine.
I am in the middle of rebuilding my 7 from the ground up. stripping it down, repainting all of it (the body that is), already have the engine apart and cleaned, ready to port, header and new seals all in a box next to me.. I will be going the haltech route for tunability.. and as you said it would be nice to replace the stock wiring harness, I don't know about your but mine is super brittle, and the sevens don't have a great rep with their electronics to begin with...
Keep us posted on how the tuning goes... Do you know anyone with a base cal to start with, might be helpful and just tune from there for your specific engine.

Von and evil pretty much cover it.
Trust me I've seen daily street driven carb 1st gen NA doing low 13's. Granted, our cars weight 300lbs more than the FB, but hey you have more HP, plus you will get more power out of an EFI system.
It is NOT a waste of money, look at it this way; with a Halltech, you will have the ESSENTIAL to have a reliable, monster 13B. Want to go turbo later on?!?!? whay not, you already have the halltech,! Want ot bridgeport your NA?!? why not, if you already have a halltech.
There is a video around of a NA FC with a Jspec engine, Halltech (or something similar), auto trany, doing over 100MPH trap speeds. It is supposed to be a 13's second car.
With a well tuned Halltech, you should be in the low 14's at least. Not to mention the improvement on a road track.......
Again, I've seen the carb NA's, a EFI should be even better. I'll bne going this route as soon as I get the $$$. Maybe a less expensive brand would be a better option (Microtech?)
