Mazworx or xsessive....opinions?

[omgshawn]

So, I'm in the midst of building my s13...getting the vh this week probably and now am looking at mounts. I've seen both the Mazworx and the Xsessive kits and was wondering what everyone's thought are on them? I do plan on going TT down the road so I want something that I don't have to worry about breaking, something I was concerned about with the xsessive flywheel spacer, but I like the solid mounts...and the price lol.

So pretty much what would you choose? Mazworx seems like a nice kit but they also seem to have a hard time answering questions about the parts they make...kind of makes me feel uneasy; I got a couple I don't knows from them..


Sidenote: I wish I could get the xsessive kit but with the mazworx machining...but I doubt it would work

Several members have successfully gone with the mazworx kit.

Hey bud, welcome aboard. I for one bought the full Mazworx kit and was very pleased with it and the customer service I had with them thoughout the entire process so I'm sorry to hear they are not really helping you, ill make myself available for any questions you have. I'm kinda biased towards the Mazworx kit as I have no experience with the Xcessive one. But will tell you the kit was as complete as they come, I did no extra running to the hardware store to pickup lil nuts and bolts...... They even include a nice lil instruction manual which is available for download on there site, id recommend taking a peek at it before hand.

C c c combo post.

Yeah I wish they would take more time to answer my questions. I think I've asked about 3 times what is used off the KA harness for the wiring they sell...still haven't answered my question. I'm curious as to why I have to send in the whole KA engine harness.

The kit does look very nice though, and is probably what I'm going to end up going with.

I got the mazworx trans adapter. The mounts and the rest I'm doing myself. I like the quality of the work they performed on the bellhousing and the adapter. I don't like the flywheel spacer that xcessive does.

[speedeast]

I have the Mazworx adapter and headers; the rest I have done myself. Check out my thread. I don't like the Mazworx mounts, the concept is too "iffy."

[gs14racer]

I had the first mazworx adapter made, and the second kit they ever made, good stuff and good quality. Nothing but good things from them mark has never done me wrong.

[omgshawn]

Ah, I wasn't sure if they did just the machining or if you had to buy the whole kit. Does anyone know how the shifter placement is with the xcessive mounts? And same here I don't like the spacer idea at all, and I don't like the design of the mazworx mounts. I was thinking mazworx adapter and xcessive mount kit/driveshaft, I'm just not sure how clearances/fitment are since it's from 2 different manufactures.

[speedeast]

If you use the Mazworx adapter, then the tolerances for the Xcessive mounts won't be correct. You have to either go with one kit or the other. Do you like my mounts? I can make you a set...

I'd be interested, can you post a pic?

[omgshawn]

What are you looking to get to have a set of them made? And what driveshaft/shifter did you use? I noticed you had to cut a little for the shifter to fit, is that something that is unavoidable? And how much farther back does it really sit?

[Dammitboy]

Speaking with Eric from X, you won't need to cut your shifter well using their kit. I'm leaning towards this kit, but still investigating the cons of the flywheel spacer. Also the fact they don't make headers is a -.

[DannyR]

Is there anyone here that is using the xcessive mounts? I know there a guy on here who has it and his car is running. But has not posted if he low the solid mounts on not. I'm very Interested in getting the xcessive kit but just want to know how the solid mounts are for street driving

[DannyR]

I meant to say if he likes the solid mounts or not.

[speedeast]

There is a picture of my mounts in my thread - the one in my signature.

I use the Mazworx Adaptor and driveshaft length. The shifter for the KA leans back, the shifter for the 300zx is straight up and down. I did have to cut some away and it is UNAVOIDABLE to do so, but the final shifter location is straight up and down almost directly in the center of the boot hole. It works out so great. I ordered a Ralco Z short throw shifter for the 300zx which, and correct me if I'm wrong, is the same one Mazworx sends with their kit. I like Mazworx and everything they've done, but I have trouble getting comfortable with the design of their mounts. My mount brackets are extremely rigid, and the mounts I use are forgiving to vibration, but very stiff none the less. The mounts I use have a lifetime replacement guarantee... if they ever fail, they're replaced. I can get them solid aluminum too. Email me if you have any more questions guys; I check it more often than this. If you want mounts and get them from me, I'll also make up a transmission crossmember so you don't have to modify your own. Again, just shoot me an email.

[DannyR]

I been trying to find your email so I can email you about the mounts. If you can email me @ [email protected] and give me so more info and prices on it all thanks.

mazworkz has all good things i personally like the xsessive alternator relocation bracket, but i had my own built, and for the wiring just contact carlh on here he did mine and i love it. i personally haven't had any issues with it!

[omgshawn]

I do plan on running the xcessive alternator bracket and maybe their PS setup. Does anyone know if the vh and KA PS pumps use the same thread pitch? I'm going to be doing SS lines for the ps system and can only find info for the s13/ka.

[newbissan-tech]

yeah their p/s setup was engineered by me and a couple other people on here a long time before they marketed it! kind of upsetting but such is life! they beat me to the marketing of it but props to them and they're alternator bracket is baller!

[hannibal]

What is Xcessive talking about here??

"The flywheel pilot on the crankshaft does require a modification to allow the flywheel spacer to seat properly, this can be done with the crankshaft in the block. See picture #5."

[speedeast]

See the brass pin... pull it out or cut it off.

I realize this thread is old, but figured I would share some knowledge.

Actually I'm running the mazworx adapter and machined bellhousing with the xcessive mounts. I just got it all bolted up a few days ago. Xcessive provides plenty of adjustment in their mounting holes. Actually the longest part of dropping it in was measuring to get everything centered up.

[s13loverdrift1]

I personally think having the whole kit from xcessive that getting there mount kit since I like the solid with the adapter from mazworx would be a good idea. Because with the mazworx adapter and the shifter relocation from xcessive the shifter would be pretty damn close to stock location. I think I might go this route when I rebuild with the spare VH I have.

[DeXteR]

I've been scheming to put a VH in my vert for a LONG time. I've been looking into it heavily again recently. I was pleased to see Xcessive getting on the VH bandwagon a while back and like the idea of some competition in the market. Unfortunately, the prices probably won't be affected by another manufacturer's swap kit.

Anyways, after comparing and contrasting all of the different swap parts that Mazworx and Xcessive offer, I've come up with the following "kit" from the two and why I prefer it.

Xcessive adapter plate -
I don't like the idea that I need to ship a bellhousing across the country to be mutilated. You'll never be able to use that bellhousing on a VG ever again (no resale). If you ever need to do a trans swap, you'll have to swap the bellhousing too. I just would prefer to leave the bellhousing unmolested.

Xcessive shifter bracket - just because it's designed for use with their adapter plate. Otherwise I don't think there's a big difference.

Xcessive engine/trans mounts - I like the solid mounts and like that they offer the trans mount. Mazworx does not sell a trans bracket - I asked them. Xcessive also includes a one piece driveshaft when you buy their mount kit. It's a pretty good deal.

Xcessive Alternator bracket - convenient

Mazworx power steering kit - they include the pulley, lines, and fittings. For close to the same price, Xcessive only sends a belt and pulley.

Mazworx intake - Good price for all they include with it.

I was leaning heavily toward the Mazworx headers, but they're such a tight fit with their mount kit that I'm uncertain it will work with the Xcessive bits. I contacted Xcessive about whether they had any experience fitting the Mazworx headers with their parts and they did not. They did, however tell me that they are working on some cast shorties, but don't have a time line for completion. They said they could make some custom tubular shorties similar to the cast one they're working on for $1200. By the time I get around to needing them, they'll probably have those cast manifolds ready and they'll probably be close to the price for the Mazworx headers.

Just my $.02 on the matter.

[omgshawn]

I agree with most of that, except..

Xcessive adapter plate - While it is nice to be pretty much bolt-on, I just do not feel comfortable with the idea of a spacer for the flywheel. Yeah you have to send the bell housing out[to mazworx] but it doesn't get mutilated it gets machined so it will be precise. And you will still have a resale value because people would buy it for their VH swap, hell I'm sure you would be able to find someone will to trade a stock bell housing+cash for one already machined

[s13loverdrift1]

I agree with omgshawn because I have the whole xcessive kit I don't truly mind the spacer because I think it can hold. But if you were to have the xcessive kit with the mazworx adapter I think that will be a very great package just because there is no spacer on the mazworx adapter set up. Plus when you install the shifter it is a little far back but sits in the stock hole. The Mazworx adapter would forsure get it set dead center in the middle which would make it that much better.

Oh by the way sorry omgshawn I have been busy and haven't really had the chance to take good pictures and when I did have time I got a little lazy because of the whole connecting the camera to the usb port which is in the back of my comp and sometimes doesn't even work. Ill take them tomorrow since I will definitely be working on the car tomorrow. I want to have it fully ready for the infiniti meet at the Riverside dealer.

Sorry to bring up an old thread...but...

Has anyone used the Xcessive VH to Schassis swap kit with Mazworx headers yet? If so, how is the fitment. IIRC someone stated if you use one kit you can't interchange parts, then another member stated you can.

I'm wanting to go with the xcessive kit over the mazworx for one reason and that is I don't have to send my bellhousing off for machining.

Now for those of you are using the xcessive kit have had problems with the flywheel spacer, please chime in.

Also, what do you guys recommend for a clutch/flywheel upgrade? I would be using a twin turbo z32 trans.

The only clutch/flywheels i've used in the past on my other project cars were made by SPEC, and I used the stage 3 for the majority of the cars I had with great results and I got used to the slight chatter.

I plan on keeping the VH45DE stock other than the mazworx headers, intake and a Rom/chip tune. Then I will upgrade to Mazworx 272 cams and valvesprings and call it a day.

I just want a fun road racing setup, and I firmly believe an S13 chassis with a mildly built VH45de will more than please me lol considering I remember watching a youtube video of Godspeed-racing's S14 VH45DE swap running an 11.9 quarter mile and I think thru an auto trans... That is plenty fast for what I want to achieve.

I went to Mazworx website and added everything needed to the cart for the VH45DE swap into Schassis and came up to $3500 before shipping. Includes:


Thanks guys,
