[Rensselaer Corrado]

who has these and what are their experiences (install, maintainance, etc.)? what kind of gains should i expect from each of these kits and other important information about these set ups. please let me know guys because im about to make a decision. thanks

Re: z-engineering vs eurotech (Rensselaer Corrado)

all i know is the z-kit is sposed to b the best for the vr6. http://****************.com/smile/emthup.gif

Re: z-engineering vs eurotech (i need a corrado)

If that's all you know, then you don't know much.

"Best" is often subjective. There are almost no simmilarities between the Z and Eurotech kits, with the exception of the result - forced induction.
The Z kit is the prefered supercharger for the less mechanicaly inclined - It's cake to install, (the kit is very user friendly), and most significantly does not require an oil feed from the engine for supercharger lubrication. Since the kit does not rely on an oil feed, the oil pan does not need top be removed for drilling/tapping as with turbo/super kits that require an oil feed. HOWEVER - Z-engineering has had issues with the longevity of their units, with the majority of issues stemming from the lack of lubrication. They claim to have these isses resolved now. Power output is acceptable resulting in approx 250HP at the crank, but less than I would expect for the $$$.
The Eurotech kit is a copy of the AMS supercharger kit with some needed updates for OBD1 cars. For one, Eurotech seems to have solved whatever problem AMS was having regarding software, and can provide software for OBD1 cars. Based on the Vortec VSQ supercharger, The install is more involved with the Eurotech kit, and requires the aformentioned oil feed line to the charger. This requires a tap welded into the oil pan for the return line. HP figures for the Eurotec kit far surpass the figures produced by Z kit cars - 275+CHP

Re: z-engineering vs eurotech (mpaster)

I like the Vortech because of the higher boost, but the Z kit is easier to install/remove.
Check out this thread if you're thinkin of going Eurotech though, also I haven't actually ever seen an OBD1 vortech dyno... http://forums.vwvortex.com/zerothread?id=152670&page=6

Re: z-engineering vs eurotech (Rensselaer Corrado)

re Z-Charger: Actually, 250 CHP for the OBD1 Corrado is a bit optimistic. I heard of that number for the newer VR6's, but was warned ahead of time that the HP gain would be much lower for the C. In my case, the car dynoed at 187 to the wheel, so I am assuming about 210 to the crank. The Z-charger is the right set-up for my case, being "mechanically challenged"

, but mostly because my C is my daily driver, and I did not want a lot of mods to the engine itself. Aside from reliability and maintenance issues, I plan to swap in a new 24-valve VR6 when the day comes that he needs a new engine. Hopefully by then there will be a Z-charger for that engine, too! Something else to consider is the extra mods you need to do when adding horsepower. With the Z, you really only have to beef up the suspension. But with any more power, you would need to add a limited-slip differential, the best wheels and tires you can afford, bigger brakes. So as usual, it boils down to how much do you want to spend? One more thing: the Z charger's chip is not really 100% there yet for the Corrado. Low revs are cursed with stumbling and surging. They are working on a fix that involves the MAF sensor and new software, it's coming "any day now." Once that fix is available, I would recommend the Z whole-heartedly. Even an increase of only 35-40 CHP is enough to catapault the Corrado to light speed! (ok, slight exaggeration.) Hope that helps.

Wow.... I had no Idea things had gone so sour with Eurotech... After reading that thread I can only deduce that Eurotech must be the southeast division of HSM/Limited VW's

Re: z-engineering vs eurotech (mpaster)

Ha, yeah, looks pretty bad.
I've never dealt w/ them before so I'm not talking trash, just warning a fellow rado owner of what is going on...

Re: z-engineering vs eurotech (GKONYA)

how much is the eurotech supercharger? i am aware of the 4k the z-engineering kit costs.

Re: z-engineering vs eurotech (Rensselaer Corrado)

OMFG paul? have you researced turbo kits? i know you want it for auto-x but 4k seems like a lot, i talked to someone i just met and he said that the schrick manifold ended up being worth every penny... i dont know my VR's but i am just lettin'ya know http://****************.com/smile/emthup.gif

Re: z-engineering vs eurotech (Rensselaer Corrado)

OK, my turn:
My 1992 VR6 Corrado was the "beta" development vehicle for Z-Engineering's OBD1 kit. There were a few problems with both hardware and software, but I can tell you that it now runs PERFECT (both Nik from Z and Garrett from GIAC personally worked on my car). Z has released a fix for existing owners of the kit who were experiencing some problems with idling, stalling, etc. Take a look for yourselves, an extra 75 hp really turned my car into a beast! The next step is stage II (adding another 20-25 hp). Feel free to email me if you have any questions.

Re: z-engineering vs eurotech (fstedie)

So those of you who have the Z eng. would it be a good step after schirck intkae manifold and 268 cams, or are these two not compatible with supercharger?
how solid are superchargers, will you have worry about it blowing?

 

[hsd16vdub]

Re: z-engineering vs eurotech (NVmyVW)

i wanna do the schrick vgi+256 cams+ z-eng with cog setup, but there is no way i would ever buy a z s/c new if u think about it for a extra 2k u can get a matrix turbo kit and have over 300 whp

Re: z-engineering vs eurotech (NVmyVW)

if you take a look at DSR's website, you'll see that stage II for the z kit combs. the charger with DSR 256's (amongst other things). 268's are not recommended because of the longer overlap. the VGi on the other hand is the icing on top of the cake.

No disrespect, but in my opinion, the Schrick is a big waste of money. I've yet to see anyone with one post really good gains (I could be wrong). After the Z kit all you need is the stage II w DSR 256s. Use the money you'd waste on the Schrick and buy a limited slip or new brakes or something more useful.
superchargers are a lot more reliable today than in recent years, but of course you'll always have the chance of something going wrong. With a turbo, if things go wrong there is a lot more potential for internal damage, whereas with the SC if it breaks you just disconnect it and drive to shop like a normal stocker.

Re: z-engineering vs eurotech (fstedie)

i had sent you a email sometime last week and have not heard back from you.

im looking to do full work to the car: cams, valves, valve springs, vgi, bored heads and tb, maybe forge pisitons with higher compression ratio, exhaust, and i think thats about it (unless someone things im missing something here for more hp/tq). what would you think i would be putting out for hp/tq and could giac modify a chip to account and utilize everything?
thanks for the help guys

[HR][/HR]​

Wow, that sounds like a lot of work and a lot of money. The above graph for my car was with completely stock engine and exhaust. My guess is that with all that work you would get maybe 20-30 hp at the most, nowhere near the gains you would get with a supercharger or turbo alone. I am sure that for the right amount of $$ GIAC would burn a chip for you. That is what they do

 

[Rensselaer Corrado]

Re: z-engineering vs eurotech (fstedie)

what about if i buy a used one with about 5k on it? would it have the same set up besides the fixes they have come up with? please let me know. thanks
yea, i think that was where i sent the email. oh well, got hold of you now. no biggy.

Re: z-engineering vs eurotech (Rensselaer Corrado)

If you buy a used one make sure it is for the same type of Corrado (i.e. OBD1 vs OBD2, distributor vs none). You would then need to buy the "recirculation fix kit" from Z-engineering. Check out their website for details on it http://www.z-engineeringusa.com
Otherwise you should be OK. Just make sure you get the chip along with the used charger, otherwise you'd have to buy that too.
