Anyone Own an FD?

Rx7 with 20b NA built high rev engine by RE would be the blank check rx7 of choice.

It's hard to take your post seriously when you suggest an engine heavier than an LS variant.

In a blank check 20b swap (ala RE AMEMIYA, peter farell super cars, etc)
The Fire wall is relocated for the 20b.

Nobody cares about the engine weight difference between rotary or v8; its over hyped and not really an issue if your check book has no issues with a blank check build; one can order a small block Chevy with 0 chevy parts inside; all billet.



Have you ever owned a fd? The car is a handful with the twin turbo rotary stock engine- its a screamer high rpm sports car- 9, 000rpm top end screamer.

Ls varient can't do 9,000. Ive driven a ls7 z06 c6 all out- 7, 000rpm is all she has.

The c6 z06 body is GM's OEM fd reincarnation with factory ls7. Its so good......but way out of my budget.

Cool, relocate the firewall with an LS7 swap. Make it an apples-to-apples comparison.

Why do you seem to hold the RPM ceiling as more important than specific output and torque?

Owned an FD? No.

Tracked sport bikes? Yes.

no need to relocate the firewall with a LS7 swap; its short and similar in weight to the 2 rotor.

with the 3 rotor the popular heavy duty tuner method is to move the firewall back to make room for the additional rotor.


I've seen what too much low end torque can do in a average joe built LSX fd; gravel all the time. I probably do not have the skills to keep from crashing one built with an average budget-

I've battled wheel to wheel on laguna with my E36M with FD LS2; the car was ridiculously rapid but quite unstable.

Ive endurance raced wheel to wheel at both infineon and thunderhill with 2x full race FC + chevy 350 and also full race 944 + chevy 350, neither are very impressive compared to a 24v e30 full race; I'd dare to say the prepped stock driveline cars were faster overall due to cornering speed/ mechanical reliability.


I have seen the LS torque/displacement tamed in an un-limited budget 900rwhp local LSx+turbo Fd rx7 car; it was built by an engineer with the budget to purchase all snap on tools and a shop to build the car first.

Most people purchasing a drop in LSX swap into FD do not have such resources.

honestly the Original 2 rotor 13brew engine is excellent and cheap to rebuild.

So what you're saying is, because people build cars they can't drive, a rotary is a superior engine.

Flawless logic.

Flawless reading comprehension;


This is a FD titled thread not a Ls kit car thread.

Lsx fans/Kit car guys cant even afford a proper lsx usually; dont even think about the rest of the car. Lsx is very popular for e36 m3 among those who dont want to pay for a s54 premium baller swap.

To each his own; ill take 3200cc with 6 throttles and 8400rpm over 6200cc 1 throttle 2V / 6500rpm anyday. I feel the premium for high rpm engines is worth every penny even at less overal rwhp or rwtq- simply not attracted to the tractor lumpster v8 engines.

A crate motor $12.5k LS7 does not have enough RPMs to properly suit a fd body. No interest in the tractor range torque as the body of the fd is not designed for it.

7k is garbage compared to 9k (stock fd oem)-11k (built street rotary) or 13, 000 or whatever the busa engine cars have.

I have raced wheel to wheel with contact vs a busa engine car; it was pretty ridiculous what 4 wheels and 13k rpms could do;

A bike engined car is much more impressive than a bike.

Bikes suck at cornering but their engines are so killer.

He didn't say that, he's saying based on his experience the rotary is a superior engine in an FD. Pretty simple.
