S62 e30 handling questions

[flyboyx]

you may notice there to be a slightly heavier front end but that can be fixed with suspension mods.

at the point you are at, i would say you would be crazy to not install that engine in your m3. you obviously already have the chassis and the engine. what more could you possibly want? you will add perhaps 100lbs to the front of the car but you are going to double the horsepower! who cares about a little extra weight in this trade off? unless you are some precision professional driver, you will notice the kick in the pants a LOT more than any lesser handling characteristics.

don't be a wuss. do it!

I have no experience with the swap, but, since you'd be adding a lot of power, could you ad some weight to the trunk to offset? Might even help with traction?

Had the same thought here. Do you think placing a fuel cell in the trunk and deleting the stock tank would help with distribution?

I'll bet the nose heavy feel won't be as bad as with some of the 24v swaps. If you go by the engine weight info seen here http://www.unixnerd.demon.co.uk/engines.html it'll have a lot less weight over the nose than an S54 swapped car, and even though the engine is a little heavier than an S52 the weight is further back.

I have an ls3 swapped vert. Handling is good with Ireland engineering race Springs. I had h and r springs but the car would squat so low under acceleration that the tires would rub. I'm now building a s62 swapped e30 m3 because I bought the chassis without an s14. My other e30 m3 has a 2.5 s14 and I can't stand having that little power plus I can't find an s14 for it. I will make a build thread eventually but need this handling input so I don't waste the money I wasted building my ls swapped e30.

I've tried my best to figure this out myself, and what I've come up with:

-general consensus is the m60 engine is just heavier than an m50, let's say with a 5 speed trans apples to apples maybe 20-40 lbs over that which is 20-40 over an M20. The m60 packaging advantage length and height wise is probably enough to be similar in feel to an M50. Every m20-m60 swap I've seen reports a little nose heavy feel, this seems to happen similarly with 24v swaps.

-according to Aquila Racing, the m60 is 10 kg below an ls series engine perfect apples to apples comparison. An s62 with all it's extra goodies should be comparable to an LS, even if the engine is a tad heavier remember the trans is 15-40 lbs ish lighter than a T56 depending 5 or 6 speed. The blocks weigh just over 60 lbs, m60 heads with gears 57 each (weighed heads myself). Crank is light at 41 lbs, so short block is not porky. Anybody with an LS swap will be valuable input.

In any case I absolutely wouldn't be worried as long as you're able to adjust a little bit with your springs and shocks, haven't heard any complaints from any aluminum block v8 swaps.

I'm in the process of building one also. Any input would be great.

So I am curious about how well the E30 will handle with the S62 V8. It is something I have been pondering for a while and if it handled pretty well it's something I may consider doing.
