First impressions...LS7 FD3S
Well, I've been running for the past month but I haven't reported on my car because of a pesky overheating problem and a hard to control oil leak. With the bugs worked out, I took it out on the streets for the past couple of days. All I can say is WOW. This was supposed to be my more reliable, daily driver car. My fast car is my 280Z with a twin turbo V8. While the Datsun is faster, the Mazda certainly gives it a run for the money. I have a Katech LS7 Torquer cam in it and the combo is supposed to give about 608 HP at a ridiculously low RPM. I believe it. What's great is how streetable the Mazda is. I'm sure it would pull away from the Datsun at first. No contest after that but there is no way I could stand to drive the Datsun day to day. What an awesome swap. I'll put up a video early next week. To celebrate, I'm going fishing in Wyoming over them next few days.

Well, these aren't very recent, but here's the latest photos I have of the RX7.
As you can see, it fits in there better than in an F Body, if the F Body were ever to have come with an LS7. Actually, it is an LS7 based shortblock I got from Scoggins that was set up for a wet sump. The car was saved from the crusher by me--it had a tiny amount of body damage and I thought it would be a shame to see it go to waste. I drove it around as a rotary for about 3 years. Then I met you guys and discovered the awesomeness of the LS motors. The swap was completed in just 4 months, with 2 months of that time sitting idle waiting for LS7 heads. I worked on it after work and it really wasn't hard.
This, on the other hand, was hard.
That's a 1976 280Z with a Chevy 383 and 2 Buick turbos. It took me 3 years and several configurations of the turbo plumbing to get it to work. It's pretty fast though.

Well as a matter of fact.....I'm having a difficult time passing emissions because of visible smoke. I may have to tear into the engine. If it's too much work, I may just get a Warhawk block since it has mounting points for a SBC, so I wouldn't have to change all that much. OK, quit dreaming .

hell, the heads dont even have to be ported, just some strong valve springs
and studs. a member on here made over 900 rwhp with stock 317 6.0
heads and a large turbo thru an auto trans. the motor is a 408 ci

nitrorocket on here made 850rwhp on 93 pump with a stock displacement ls1, stock crank, stage 2 or 3 tea 5.3 heads, little 224/228 cam, and twin 61mm turbos with a2a ic & th400/12 bolt combo. no need to go the high dollar route unless you plan on making a lot more power than that.
