Yeah thats a good one.... I have my old ECU as a paper weight on my desk now.

I have my S5 engine setup running with all the emission controls in tact. My engine actually runs now and let me be the one to say, modifying that wiring harness was a piece of cake.

Its not this gigantic headache that it seems to be. Hell when I started my project I didnt even know how to read a wiring diagram.

I'm currently working on my howto for modifying the S5 harness for a S5 engine swap. Its a piece of cake, theres about 10 wires that you have to fab up connections for, and thats it.

Mmmm-hmmm, no doubt. Tell you what...

From now on, when I get these idiots emailing me or calling me asking how to put a 95 TT 13BREW in their 79 rx7 with the 12A carb, using the stock electronics, Ill be sure to send them your way, and let you explain how simple it is.

I didnt say that things like this COULDNT be done, but I will say that a) 99 out of 100 persons could not accurately reproduce these results, and b) most of the time, the means do not justify the ends. So you successfully transplanted the stock s5 stuff into an s3 car...you gained a whopping 25hp, which could have been gained with other mods to what you had (see Mike's car).

Sorry, I didnt mean to come across like a smart *** like it looks like in my post.

I just wanted to point out that once you understand the systems you are working with, it doesnt become much of a headache at all. And using a stock S5 ecu and wiring is commonly known to be a gigantic pain in the ***, and I wanted to say it isnt.

But just so you know
well I had a 12a to begin with so thats 105 HP to start, the S5 N/A has 160 stock.

Looking over your post, with that 25hp number you probably thought I had an SE to start with. Sorry I didnt mention I had a GS.

I'm sure a 13B REW would be much harder to swap over the wiring, as there are many more sensors and such that go to the more advanced CPU. Now I didnt say that it couldnt be done, but you said that there is no way it can work.

Not trying to start a flame war here, and again I realize I came across as a smart *** with my comments, and I'm sure you have done this kind of stuff way more than me.

OK guys... this thread is rather old BUT...

Is it possible to do this "mod" successfully...(adding about 20-25 HP) and then add more HP with other mods such as RB headers, etc.?

i.e......Ok so you swap a 2nd gen. manifold into a 1st gen, remooving or wiring open the sleeves, and all the other stuff. What other related mods can you do on top of that, adding HP? It was mentioned that this mod was completed with a RB exhaust system. Does that mean that this TN guy did his "mod" that added 25 HP to the basically stock GSL-SE (with a full RB system)?

I know this is confusing... just trying to get some answers.

My exhaust system is the same now (except for the now hollowed out cat) as it was when Kevin did the mod. Stock mainfold with RB muffler. I plan to get to the track sometime to see what kind of times I have, but I'm Im the middle of break-in with the rebuilt engine (Kevin put in a mild streetport).
Hope that sort-of answers the question.
I suppose an RB header would add something, kevin has told me that a header pretty much adds more noise than anything else, others on the forum would strongly disagree.

First off, I know this is an old thread, but I just wanted to give a big thank you to Kevin for taking hours out of his life to write up that uh.. write-up..hehe. One thing though, headers make a HUGE difference. My Mindtrain headers have made the car quite quick and far more fun to drive. It is a lot louder, but it's a "nice" loud, if that makes any sense. I did lose a bit of low end torque, as they are quite big (2.5" extractors) compared to the Racing Beats, which are only 2". From my butt dyno they do pull harder up top, which in theory they should. I've driven another SE with RB headers, RB presilencer and stock muffler, MSD ignition, and K&N drop in filter and it felt better off the line (thanks again Dale!) but mine still felt a little more punchy up top. An SE with stock exhaust can keep up to me until 5k in 2nd, when I start walking. It should also be noted that my 6-ports ARE indeed working to my knowledge.
Sorry for the rambling, but this is a very informative thread and YES this mod works wonders (although I haven't completed it yet) according to several guys in town who have done it.

excitingleopard

I'll take both of your word[s] for it then. I shouldn't have brought up the question, I should have just driven to TN instead. I'll just do that sometime soon and let Kevin tell me what's going on. Thanks.

This is the engine that required ANOTHER rebuild because Kevin messed up the Pineapple post install, and they came loose?



Ahh, I'm just funnin. I know Kevin did a big write up on those to help others with the same part, since Pineapple didn't provide install instructions.
How long until the engine is broke in?

hypntyz7

Kevin didnt mess up a GD thing, I can tell you that right now...

excitingleopard

Well thank your for sticking up for your........



.....'buddy'.

To put this to rest, I ordered the sleeves myself, brought them to Kevin and asked him to install.
Nobodys fault that happened, just one of those things.
No harm done long term. I got about another 800 miles left for break-in, gotta drive like the old fart I am until then!

spoolin

bump for someone looking for this thread.

and how's the car running?

mwpayne

Excellently. Got about 2500 more miles on it now (just a fair weather car ), absolutely no problems.
I still say, you GOTTA do this mod!!
Just bought an 88 vert, saving the pennies for the eventual Landers rebuild..

I just had Kevin do this same mod to my car and I gotta say, the results have me impressed.

This is on a car with functioning 6-ports, full Mazdatrix streetport dual exhaust system, Mazda Racing underdrive eccentric shaft pulley, and cone intake. The emissions were still intact-

Since I don't live where any testing is required he removed/blocked off all the emissions, swapped intakes, and installed the infamous Pineapple Racing sleeve inserts.

Wow!

The car has so much more top end punch it isn't even funny! The low end grunt seems to be about the same as before, too. It may be a tiny bit less, but certainly not enough to really notice. The only noticeable driveability difference is a little shake at dead idle as the ecu hunts for a good mixture or something. The engine itself is just as smooth as ever, and the idle isn't an issue as it actually idles pretty smoothly, just a bit higher than before.

Gas mileage on my 1,000 mile trip home seemed unaffected. I'll have to see how it likes being romped around town this Summer

I don't know how much of the gain in performance to attribute to each thing done to the car, but it is most certainly faster than before. It pulls hard enough to redline now that I may start to worry about my 100,000 mile engine!

Oh well, if it pops I'll have an excuse to get it ported next time...

Enough rambling, but I had to bring this thread back because I would absolutely recommend anyone with a stock/mildly modded SE do this.

mwpayne

My experience exactly!

Your idle will smooth out (at least mine did) after 1000 miles or so. I adjusted the TPS after that, now very smooth idle at 800 RPM. Of course my sleeves are now totally removed, don't know if that has anything to do with it...

3000 miles later, couldn't be happier with the job!

The other cool thing is that the cold idle is only 1500 rpm's. I always hated that cold start assist...



It's a very clean install as well, I like the way it looks. The engine note at high rpm's is even better than before, too.
