2j or not 2j....

So, I'm currently driving a Volkswagen Golf GTI 337....very rare "nice" car... I got rid of my 360rwhp 240sx SR 'vert to get a "nice" car, and then realized....I don't want a "nice" car. I want a high horsepower beast that I can beat the crap out of! I am planning on getting an FD and doing a highly modified 2JZGTE swap, and was kinda wondering what you guys thought of the idea....

that is the question, whether tis nobler in the mind...

I dig the thread title, but not the idea. Then only swap worth doing in a FD is an LSx swap, imo. A 2jz will throw off the weight distribution and ruin the handling of an FD. If you just want straight line performance, why start with a FD chassis?

Well, I don't want just straight line performance. And as far as the LSX...no thanks. We have already done both an LS1 and a 408ci V8 in a 240sx and I'm frankly kinda tired of it. I haven't done any intense research on the 2JZ into FD swap, to be quite honest, but I do know it has become quite popular. It just seems that such a popular swap couldn't possibly do too much damage to the driving characteristics of the FD? Besides, being a race car driver, I have all of the equipment I need to better balance the car should the swap throw it off too badly. I appreciate the feedback and I'm open to constructive criticism! Keep it coming.

why not do a 3 rotor setup instead of 2jz? look at this way you'll still have six plug wires too. i hate a piston engine in a rx7. just my 2 cents

I have never driven a swapped FD, but I would think a fully dressed 2jz would weigh alot more than the 13b. It has all the same turbo accessories plus an iron block. More weight up front throws off the 50/50 weight distribution, therefore, poor handling. I don't have hard facts though. I would be cool if someone could chime in on the actual weight of both engines dressed.

I am sure the FD doesn't just suddenly handle like a 'tank' either. Face it, the 2jz is always going to be an awesome engine. The FD is always going to be an awesome car. Putting the two together can't be all bad. It's just not my cup of tea.

Well, by personal experience, too much front weight could cause a bit of oversteer....not bad in my opinion but still not a well balanced car. To correct this issue, the suspension should be tuned accordingly. You could use a larger front swaybar, eliminate the rear swaybar, set the front suspension more firm, set the rear a bit less firm, all to compensate for the less than perfect distribution of weight. All of these things are easily done with a good set of aftermarket fully adjustable coil overs along with other angle adjustable links in the suspension you could have a 2JZ swapped FD that handles even better than a stock FD where the weight may be better distributed while the car is setting still. But overall, where it matters is on the street or on the track, where the suspension is doing work rather than setting idle...

And as for my argument about piston engines in an RX7.....just listen. Simple as that... For me it is the high pitched, raspy, throatless, non-intimidating, tones that pour from the exhaust that cause me to cringe in disgust and run far from the rotary and all of its woes.... NO AMOUNT OF POWER FROM A ROTARY WOULD EVER CHANGE MY MIND... period. (this is just my opinion, it matters only to me...)
