Planning on going old skool and building the motor! Now who makes custom pistons and cams and what not? I heard that the compression has to be almost the same and I was nervous about installing mopar pistons and rods. Aparently the old chargers could work too even tho its a V8. Any idea where to get these items done at?

Ummmmmm, okay. Custom internals are in aisle 5, right next to the headers. If you see the superchargers, you went too far.

Damnit the clerk told me it was in aisle 4! But seriously tho, if a single cam can have aftermarket internals, why can't we? Maybe I shoulld have said aftermakret.. anywho, throwing on the bolt on basics seems boring af and too much money for little gains. The supercharger is nice but I wanna make some true hp

If you want to make some true hp, you would sell your car and get something else.

The N54 has forged crankshaft, pistons and con rods. I'm not sure if the parts are a direct swap to an N52 but that'd be one way to do it. I don't know of any aftermarket company that produces forged internals for these cars except for VAC.

You'll spend thousands on all of the bolt-ons you could potentially buy and maybe see 20hp from them. Not worth it IMO, and no need for forged internals unless you go FI.

Nothing else handles like a bimmer. And I'm not gonna downgrade to a older year or get a 335 with cash I don't have.

What's FI? And I was thinking that early because I wanted to change the compression a bit and micro port and polish the block. I've seen a few all motor monsters destroy heavily boosted supras and other cars with nos with no sweat. I wanna be legit without being too outta the box. What happend to the tuning world were you can't even change simple things as cams and pistons?

[RupertPupkin]

It has been said that the cams we have are already the best they can be. Theyre light (hollow), strong, and an aggressive and optimum profile.

Personaly think a stroked N52 is the way to go. There are a few compani9es that make a kit but it is upwards of $10-12k

Gets you like a 3.2 or so liter car, but over 300 HP and probably sounds nasty.

go M3 V8!!! lots of "stock" parts and more power!!!

FI is forced induction. Really the only problem with building the engine is that the N52 is pretty good already. As a result you don't see much aftermarket support for things like forged internals and what there is, you spend so much money for such minor gains. If you want big power then Im afraid there are better engines.

Damn that's a lot of stroking and money, will our pistons be able to fill that voided gap after stroking it? I was looking for pistons in the first place and the old e46 pistons seemed to do it being that its already 3.2 any thoughts? And how would it sound nasty?

Lol I was planning on it later on but I wanna beef the n52 up and see how good it gets, if I can stroke it and make it spank on a m3, id rather keep the n52 and some money cuz the motor alone is expensive not to mention the new tranny, new wiring harnesses and I also have to weld on a m3 rear end to compensate for the powering being made and the cost of having someone install it. But nice idea tho

True, but I wanna see how much I was whip out before the motor gives out but ill keep your words in mind, thanks for the insight

You basically replace all the internals. The rods are probably different lengths, different crankshaft profile. Basically increasing the stroke of the engine and increasind displacement while maintaing a high Compression ratio.

I say it would sound nasty because I think it would have a bubbly angry sound if stroked. You tube some stroked motors.

No prob, personally I think that it's awesome that you are looking into this because this is the kind of tuning that I love.

[_Ryan_]

As much as I love building stupid motors, it will be more cost effective and nicer to drive if you do an S65 conversion.

Also gives you a good basis for further power, I know I get bored easily...

[mapleridge]

Great convo going here guys. Don't have a clue what stroking a motor is but I will research it after this. Main problem with AT it seems though is the inability to take a lot of extra HP. How, if at all, could the AT be upgraded with the engine?

True, but I wanna see how much the n52 can whip out, i d love to have a v8 but the cost of installing and getting everything new sounds too much for me, at least this way, the cops can't mess with me and I don't have to barr the motor to my car

Hey, well most people now think,"oh ima throw a boost kit on and be fast." True but why not build this motor and then throw a boost kit later and be even faster than the last guy. Id love to say that I have a full built n52 with micro port and polish it seems like I can hold my head higher

Ooo those are some gorgeous numbers! But I have a 328 lci would it still be able to work? And what company does that?

Stroking the motor is creating a bigger bore for your pistons and for the AT, id say upgrade your diff. And possibly your gears. I'm not too sure if they make aftermarket gears though? Then again you could learn how to drive stick lol its a lot of fun and many more possiblities without lag

[RupertPupkin]

Not to be an ass but you're wrong.

Stroking is increasing the stroke. Distance the piston travels. The bore stays the same
Hence the term "stroking"

My first car was stick. I have an AT though. I'm hoping like the E36 crew we will be able to swap AT for MT at some point.

How can the piston travel further? Is there additional room that is tapped with accompanying parts?

[Rotorocious]

You will end up spending far more building up a n/a motor than just getting a better platform to start with.

Good luck.

The crankshaft is more aggressive so the piston moves further down into the block. This creates a longer stroke within the same engine block. Boring the block is different.

Different rods, crank, pistons.

Ohhhh that makes sense, and you're not being an ass, you're just correcting me. But how neccesarily could you change the travel and add more liter versus the opening the bore?

Nicee, I love my car more that its a stick. Honestly so much more fun to drive

Getting an NA wasn't my choice really. But id rather start from an error free lighter platform than a 335 and a m wasn't gonna work in the long run being as gas prices suck and oil isn't cheap either. But thanks for the support
