Hey guys, I was just giving the heads up on my latest project Ive been working on. Its a solid engine brace, scca DSP legal torque supression device, for the KA24de s14 chassis.

Basically the scca states that a TSD can only limit the motion of the motor on one axis / one way. Its either a link with rod ends or a chain / cable. The down side is only one attachment can be used, so by using a chain / cable you only restrict .5 of an axis... Also only oem engine mounts can be used in dsp (nismo / solid not allowed).

So, I set out to fabricate something for the KA with these requirements in mind.-SCCA DSP class legal-as rigid / strong as possble-utilize stock mounting points (no pulling from my stb bracket) so that it can be mounted on other s14-quick and easy removal if need be

So then I set out and created this, the Enigmatic Industries (me and my friends group, we label all coustom / one off projects as EI projects, and hopefully buisness one day) engine brace v1.5 (explanation later). The only things I had seen prior to this where SR / S14 engine braces with a damper on them to limit vibrations of the engine. The mounting location was a place on the head the KA simply didnt have, plus I wanted a relatively solid unit for auto-x. I hadnt seen anything legal on a KA so, lets just say it was a b**** at times, hehe.

As you can see it pulls from 2 14mm eaxhaust manifold studs, and 2 14mm strut tower bolts. What you cant see to well is the triangulated strut tower brace that ties in with the 2 10mm bolts on the power steering resivior bracket as well (doing this removes any movement, and when you pull on the ST brace it pulls up on the car :) good stuff).

Originally it was the head mount, and a crude brace that tied into the stb bracket. It worked for a day (well would still be working but I wasnt happy with it) but I needed it better and rather universal :) (thinking that if friends wanted one I wouldnt have to redisign the pig). That was v.1, and v1.5 is this brace as it sits.

Its still not done and I hope to have v2 up tommorow or the next day. Changes are as follows:-finish grinding some of the welds for a cleaner apperance-overhaul head bracket utilizing square tubing also I will brace the angled bends where they meet the head as this is the weekest link.-use a reverse threadded rod end and center turnbuckle so that I can put on the center rod loose and tighten it to its current pretensioned state vs pulling on the head then adding the rod bolts to pretension it...

Its been a fun project and my gf and friend want one as well, but they have s13's... I test fit it today on hers, but the aiv will need to be removed (finally), heatshield trimmed to work on the stock manifold, and the lower bracket of the strut tower brace will need to be slightly modified as well. It made a decent improvement at my last auto-x on the 27th as well..

Hopefully Ill get it finished (probably not painted though, as the currect paint was a mock painting to see) tommorow or the next day (may not have the endlinks fixed though, Ill find out tommorow if itll be special order or not), and if anyone is interested Ill post the final images...

Also if anyone has any comments on it Id like to hear them.Good times...

what type of metal stock did you use for the fabricated/welded brace points?

Very cool indeed...any idea if it would fit a CA? I cant give you measurements right now as the engine is in the garage and the car is outside, and I'm 30 miles away :)

I dont know if I will market them... If I do it will probably a short run of them as It takes a bit of time doing them myself. The fact I havent seen one like this brace or a legal dsp (IT* as well iirc) brace for the KA, made it rather fun to fab.

I have to run in SM now anyway as some minor things like replicated nismo brace, subframe spacers (washers of course) and slotted rear brakes toss me out of dsp. So if I could sell a cpl to help with future SM projects (RUCA's and all metal rear spindle bushings as splparts charges 750$!!!) thAt would be cool.

Also this is one step shy from say solid engine mounts, so the target audience would be for people who know what this is for :) But unlike a solid mount the center rod is removable in 2 mins with hand tools "hot", and I may see if a cotter pin hold could suffice for a 30 sec removal hehe. Only other type Ive seen has been for the SR using a damper shock and from hpi, a japanese company... and for 18k yen.

I could definately pull out s14's with headers, removed heatsheild and oem manifold, or oem manifold and slightly trimmed heat sheild. As it should fit all, as I checked my oem mani today.

The s13's could only be applied to those with aiv's removed, and likewise with KA24DE (as the runners change on the E) and manifold / heatshield options. I will be fabbing up a ST bracket with a new lower 3rd mounting point and fitting it to my gf's 92 as that is all that differs between the two, along with possibly rod length. Ill find out soon enough, as I need to make 1 mabey 2 for my gf and friend. His may come now with a sr revision later but who knows.

The only downsides are s13 ka24e's and s-chassis sr swapped cars as I dont have those available. But if you are seriously interested in a s13/ka-e (but probably wont work for the sr in your plans) mabey I could work something out... If I did, it may be a while as I need to dbl check the mani and ST of one of those.

Like I said it was mainly a side project to get me off of this box, and give my laggy automatic a55 a little help in and out of the corners... Actually got to feather the throttle at the last event to got some controlled rotation, which was nice.

Im sure Ill have some other one off spins like my friends s13 with sr (getting a free 93 drivetrain from helping him swap it) and my ka with FI one day, even though everything may be solid at that point... What the **** Im a SM'r now ....

The points are all 1/8" hot (possibly cold.... its late and I cant remember) rolled steel bar stock. I was going to use 3/16" crs stock but the strut tower nuts would be one thread shy of fully on. The 1/8" works good with 1 thread to spare, even with a tanabe strut tower brace bracket as well, as Its more assuring to me. FWIW the stb bracket (tanabe) is 3/16" stock.

For the CA I have no idea if it would work as it would need to go above the hot pipe im guessing. This would require a different type of strut tower bracket, as well as a different head bracket.

Oh yeah thanks for the comments you two.

EDIT- I see 240-keyy is running a not so legal dsp car at the 4-13 event!!! All but one dsp car is a 240, but all are nissans.... Are you in agreeance with them for your mods?

nathan if you want one for the CA let me know we are starting some custom fab work on mine in the next 2weeks... we are goin to run off some exhaust systems and engine braces for the Ca18det and sr20s.. we are also goin to make a test pipe and maybe a tubular manifold for my ca and one for a 1.6 honda for a t25 turbo! we are goin to be really busy this summer and so so broke .. we will soon have up our first version of the our site!

If your not marketing it, someone should. I'd buy one for an S13 SR

I really didnt think there was a demand for a solid engine brace / torque supression device... I didnt see any readilly available so I didnt think there was much need....

For that sr issue I may have to see if I can some time in the bay of a local one.... If not Ill have one to play with in a cpl months...

Well off to fab v2 and possibly an s13 one.

Thanks for the comments again, its appreciated.

i wonder if it would clear the turbo on my nsport kit that is coming in? if it does i would take one in a second, ill test it out for you if you want.

Well I special ordered a left rand thread enlink to that I could pretension them, and later found another outlet for them, so Im happy. I also found some other things I needed to bring on new projects... finally.

But finding a 3/8"-24 left hand threaded rod is a *****. I found some in 6' length, and may get creative with it, or get the die and make my own studs... We'll see.

I might go to my college graduation as most of my class is grad' this year tonight. So I get the stock and work on the s13 bracket, then comes finding a s13 sohc to work on as the head studs spacing, and location differ. But if there is a demand for the s13 ka-e Ill make a few up.

For the N-sport I dont know as Im not 100% familliar with it. Ill look into it tonight possibly as I may have to change a few things, and It may work.

Thanks again for the comments and Ill see what I can do to fab some up, and possibly pricing per complete unit.

SHHHHH!!!!!!! :D

lol, we are real slackers at our events, I ran in DSP cuz all the rest of the people are my friends and they don't care. I took DSP by storm this semester though and got a pimp trophy. I have no idea what class I am really in now.

BTW how did you find the results?

profile > homepage > events / auto-x > auto-x results page > spring 2003 > auto-x #4 :) even though there where a cpl ka-e's your profile also gave your fist initial and last name :)

Brakes dump you out of dsp and into stx, but the spacers spherical rod end t/c rods, and lsd all put you in SM. The SR swap will keep you there as well. Unless you go drastic / remove interior (back seat can be removed in SM) you should be fine there for a while, just dont go into straight prepaired /modified as thats where the really big dogs play...

ahhh this is true. I am definitely going to run SM if I go anywhere else, but we have a class called Super Street Mod (SSM) that is a catch-all street tire class in which anything goes.too bads you live in florida, our autocrosses average about 1.3 miles :)
