I think you should be prepared for a lot of attention and head turning whilst driving it.
Best of luck with it mate.
Thanks! Like I said, no intention of giving it up, and I want to be able to keep it on the road for years and years to come. Internal parts from a W136 aren't getting any cheaper. But I have requested a quote from the Classic Center for a new motor and trans for this car if I went the original route. No word yet.
I've been thinking about going a step up to the VG30DE, since they seem to be a bit more common around here than the non-turbo'd cars.
I just got out of a 91' 300zx (Non-turbo). I would HIGHLY advise getting the above mentioned motor. The Vg30DE is a spectacular engine with plenty of torque. They love high RPMs. 4000-6000 rpm makes such a beautiful sound. I Have owned 2 of these engines over the last 6 years, and I have been alternating between OM617 and VG30de.
I would not even fool with the older Vg30 Single cam/dual cam. The difference in design was IMHO much much better.
If you are looking to get the most bang for the buck, Buy yourself a wrecked Twin turbo, and use that. If you have room for a Vg30, might as well make room for intercoolers and downpipes.
I have a RLF who had his 95' TT Dyno'd at over 700 RWHP. He had quite a bit of work done to the car, but There is nothing sillier than having that much "GO BABY GO" under the hood.
I got rid of my 300zx due to my biggest driving fear being realized. Snow + RWD + Horsepower = telephone pole.
It was the ONLY car I have ever owned that scared me. Too light for factory HP, but on a dry road the car was very intuitive. It knew when I wanted to go sideways, and would always straighten out when I willed it to.
Im guilty of buying cars based on their power train, and the TT Engine and Transmission are some of the best ever made.
The idea is to get a running car, to use as a driver while I polish up the 500 again, then begin the swap over to the 170. This also allows me to verify that everything with the motor and trans is on the up-and-up.
I appreciate that at least some folks understand I'm not going for originality under the hood for the sake of extending the life of this car well beyond those who have their original drive trains. It'll be rare one day anyway, right?
I've started the search here for a 300ZX that's appropriate for me, knowing I can probably fit in the TT, I can look at the '90+ 300ZXs instead of stopping at '89.
