'91 TT owner.... Son spins out and smashes left side wheels into curb. lots of bent suspension parts, so after tuning up son with steel toe boot, I locate a complete suspension from a N/A zx.

Of course when I get the rear subframe in place it's only then I notice there are no mount points for the Hicas rear steering...

Can I just remove the Hicas and send the power steering fluid back to the pump by connecting the two hoses together. And if so is there a fitting that will do this without having to destroy the hose ends?

I've seen the rear steering eliminator kits sold but it looks like they mount up to the same points the Hicas does. I'd want the same performance gains on the cheap with the correct fitting if possible.

Get a non-turbo power steering pump.

And you know the NA rear end is 4.902, as compared to the TT's 3.692, right? More importantly, that your son's car will now accelerate harder... sounds like the opposite of what you'd want.

I did not get the differential, just the subframe, hubs and arms.

It's my car not his, so he won't be driving it anymore. Maybe I should locate the differential from the NA also??

I think you're best off leaving the stock TT equipment. It's stronger, increases gas mileage (the larger NA rear end means you'll be at a higher RPM for the same speed), and HICAS is an amazing system. But that's just me. Do what you want.

there you go. And if I remember right. the TT rear diff doesn't fit on the NA frame.

If memory serves the early q45's used TT rear subframes without HICAS. Do some research on it before hand though.

I was actually thinking the same thing, but I don't have the experience to back it up... I'm a fan of both the stock TT rear end and HICAS, so I never researched getting rid of either of them.

I'm tempted to drop my N/A protect entirely and see if I can find a nice clean TT the HICAS sounds interesting. Tho I've also heard some horror stories too lol

ZLover4Life

You've heard horror stories from bad drivers who wanted to blame the car. lol

For super-experienced drivers, it can slow them down if they're not used to it, and the weight becomes a serious factor. For poorly skilled drivers, it's a scapegoat. For everyone else, it's awesome. And I even know one person who frequents Solo II events and loved HICAS (Luke at Tire Rack... used to run his Z on their proving grounds frequently, until he switched to Porsche).

Thanks for the link. That exactly answered my question.

But, now I'm bummed that the Diff will not fit.....

Off to look for a complete suspendsion... a N/A diff, or a TT subframe, whatever is cheapest and available quickest.

Just so I'm not further surprised....
If I change out the complete rear suspension to one grabbed from a NA car, will there be any issues connecting to my existing drive shaft (length, etc.)?

Uh if you manage to keep your TT diff it shouldn't matter.
