As for the engine in my M3, I love the M3 in it's stock form and I want to be able to have something with a little more power and some peace of mind that it is going to last the test of time. There is a good chance that when my engine comes apart it will be perfect, but in my opinion, once you remove the bedplate the engine deserves nothing less than a full build on the bottom end with properly specced clearances. As I mentioned before, I will never be parting with my E90 and I don't mind the investment since for me it will last a lifetime.

Yeah I understand your thing about the peace of mind as I come from a 09 STI with 4 blomn engines in less the 25k miles, 2 of them out of warranty and all that only because of a Cobb stg2!!

But still, if one absolutly need bulletproof reliability, I think the best option to not completly waste $30k would be to put a VT2-585 on a low compression engine! Again, that's just my opinion, but I would'nt be surprise if you had never drove a blown M3 before to say that you don't want a blower because you want stock like power delivery!

Anyway, different stroke for diffenrents folks they say. If I was building a muscle car, I would probablykeep it N/A since there's so many options to go fast, on the other hand, the S65 needs a blower to go fast!

Fast is not the only thing to a car! By adding a SC you will lose the beautiful induction sound of the S65 and it is a dead giveaway that it will be fast when opening the hood! I am going to do a stroker with Schrick 292 Cams and upgraded valve springs so that the thing can really rev and make power up top. I am hoping for 425+WHP NA if that is possible........ Now that would be a sleeper!

It would surely be a fun car to have an N/A M3 with 425whp. And I'm sure it's doable since some reach 400whp with only bolt-ons. Also, I completly understand why you'd like to keep this car forever and I also understand why someone with deeper pockets would still want to drive an m3 V8 instead of let'say, a new 991S!! Hopefully you will find everything you need in that stroker that you want to build but before you make your descision, please, do me a service and go drive a supercharged S65!

The only thing missing from a low compression build vs. stroker is the crankshaft. All other parts and costs remain the same. Not really saving much $$$ with this route.

I was under the impression that a low compression build would cost around $15-20k and from what I understand a stroker is nearly $30k so there's is still a big price difference, a difference that can buy you an other 100-150whp off forced indiction!

I'm really no expert but I thought that you could just drop pistons in the engine and a couple of other parts to do a low compression S65, that seems less complicated then taking a 4.0l and bringing it to 4.6l, maybe someone can chime in about that!

I know how great the ESS SC'ed cars work, even though I haven't been in one. If I wanted the fastest M3 dollar for dollar an ESS SC would definitely be in my future, since I like to be different a cammed stroker is in my future!

The only cost saving would be the price of the crank and boring the block........ You would still need to prep the bores for the new pistons/rings and replace the rods. While the engine was apart, it would be stupid not to set clearances on the mains and rods!

If you wanted your LC engine to be strong and last the build is still 85% as involved as that of a stroker build. Sure you could just drop pistons in but that would be half assed in my opinion, especially when putting boost in an engine.

[kiln]

Does anyone know the weights of the connecting rods being used? I was wondering what the difference in weight are between the three?

Carrillo A-beam vs H-Beam vs H-Beam-HD

Heard deez cars were monstas. Real Beece! Got dem Red Fox leather.

Probably driven both these cars, aight.

Yeah!! We need a Pkilla authentic review!!!

Absolutely Nuckin' Futs!! 201mph in ONE mile? DAMN!!!

So you guys swapped a DCT into a Lime Rock Edition?

I really love the one of Dinan's...
But that price you can buy a brand new GTI with 200hp...

[pkimM3r]

I personally like na. Its not gonna be the fastest but itll sure give a bump, delivery power nicely and be reliable. I wouldnt even be able to use the full potential of a supercharger on track anyways.

But i gotta say alekshop. YOUR CAR IS BEAST. If im ever in norcal i need to come visit.

If it is only 425 whp you are after than you can skip the stroker and just go with the cams and valvesprings and a proper tune from evolve or ESS. I may go this route and looked into it and from one of the reputable tuners on this site said 20-25 whp with cam's and the right tune is what they have seen (even more on the e46 m3). So if you are full-bolt on plus you do cams, you will be so close to 425 that the 30k extra for a stroker to maybe hit 440 hp would really be not worth it.

Cams on the stock S65 will probably hurt torque a little down low even with VANOS!

The stroker will allow the power gain up top yet still gain torque down low! Plus I am gonna use the stroker as an excuse to upgrade the rods and set the oil clearances.

[Longwong]

Well you are right there. If you want more low end torque a stroker is key. I guess I feel most that would be putting this level of performance would want to enjoy the power up top which is what I do and would continue to do but hey if you are really wanting to spend 30k than you will certainly get a bit more low-end torque. I guess it depends on the purpose of the car. If it were to use as a track car or a street car that you loved to rev it out than stroker seems to be a waste. For a better daily driver to some if you think low end torque is key than clearly it is a no brainer if you have the dough. I don't know I think you could add the cams, springs and upgrade internals and go for 9k rpms tune and really keep true to the car and have a monster above 7k rpms. It would literally keep pulling to the moon if we got it to 9k. It would be the longest wall of power ever. Just like stock, where else can you find a absolute wall of power straight from 6k-8400 that just keeps pulling and pulling.

Will be interested to see your dyno with stroker and cams

[Jonjt]

That US spec GTS build needs to spin faster.

[hyperboost]

I like those striker motors but the cost here is a big chunk of change. Those dyno numbers aren't impressive btw, especially the dyno is a Dynojet!

[MDIVISION]

I love my E92 M3 but yhis is another reason I'm looking forward to the M4. Almost same modification might cost $3000 instead of $30,000

wow
