Z impressions from a GTR owner

Lug

Personally, I'd be a bit nervous running 660hp on stock internals on a Z. That's got to be really pushing it. I'd also be willing to bet that just upgrading the turbo's on the GTR is going to be a bit easier and assume the internals are quite a bit beefier.

Where do you find a track that you can drive on ? We live close ( enough ) to Infinion to drive there, and that would be an absolute blast, but as far as I know the only times it is open to the public is for drag racing, which will be nice in a couple of weeks when my wife's new 2SS/RS Camaro gets here ... but as far as I know they never open the road course to the public, which is a shame, because that is what I would really like to run. I tried checking the website for Laguna Seca as well but couldn't find any info for that track either. Both places offer racing schools, which I would like to take now, but I would also like to be able to take my own car(s) out. Anyone know of some tracks that are open to the public ? Maybe a road trip is in order ! : )

The gist is that someone rents a track for a fee, say $6,000 for the day. Then the organizer charges $250 per person for the track day. Quite a few groups do it and you should be able to do it at laguna or sears point. If not, buttonwillow does them for sure.

I would send you a link from other threads, but I'm on iPhone and it doesn't copy and paste.

The bolt on sports turbine twin set up for the Z isnt going to get 660. You can achieve maybe mid to high 400's but not 660. Going by the post you are quoting. There has to be more done to get above 500 than just bolting on turbos and an intercooler. You will be restricted off the rip from fuel alone. Stock injectors are only rated at 440cc......for starters.

The trouble you'll inevitably run into is trying to set your boost too high without having enough fuel....run lean......destroy pistons and rings. The internals themselves will handle the load, if the rest of the equation is correct. Burning rich wont hurt internals, but your power will be limited until cams are changed. Engine response wont increase until the crank is changed. The only stock engine part that will give without over boosting and frying a piston will be the head gasket. And that is a guarantee.

As far as what was said for bolting on different turbines to the R and getting more power cheaper......ahhhh dont think so. Its rated at 500hp already. So youll already have to go bigger than the HKS 2530's to generate that. Not just a simple turbo change out and get more HP. With the old inline 6 you could change out the manifold and run bigger twins with ease. Not with the current engine used. Gotta change fuel delivery, different manifolds, larger than just a sports turbine, and most importantly get rid of the rediculously small intercoolers. I think the water cooler at work has more heat transfer than those rinky dink things.

Thanks !!

I go with track masters and SCDA. Mostly NHIS, Lime Rock and Watkins Glen. I do indeed go through a bunch of tires. I have Nittos on the car now, we will see how they hold up.

How exactly is the GTR limited in upgrades?
