Installed 2JZ engine, few questions on brakes, etc

Greetings all.

First and foremost - this community has been an awesome source of knowledge and such a large collection of wisdom . It's been a massive help for a long time now. Thanks!

inb4 gO READ STICKIES.

I have a few questions about something most purists will think of as blasphemy, sacrilege etc etc etc, bla. If you don't like it, well..

anyways.

I bought an e46 318ci 4 years ago, did some minor mods (wheels,tyres, bumper,lights) . Recently found out it had some major accident damage before it was sold to me ..all repaired though. I replaced all the major senseors (gb,maf,cooling coil etc) when i got the car. Had lotsa lotsa dash light popups, which were solved with sizeable amounts of cash.

One day, i just realized that the engine was taking up too much of my time, and the performance wasnt worth it. I wanted a stickshift, and power to get out of tight spots - a full on bmw engine conversion was way too expensive, and we dont have GM small block V8s here.

SO I DROPPED IN A 2JZGTE.

with an R154 5spm MT.

besides the lifetime bits (water pump,plugs,fuel pump,clutch ) and some mods (silicone,SILICONE EVERYWHERE!, fuel pressure gauge, turbo timer ,(stolen) boost gauge (damned thieves),coilovers) the car hasnt given me issues.

well..except the time a friend tried to launch it from 6000 rpm and the right axle sheared off.. it's been a great daily driver, and also satisfies my 0-60 cravings every once in a while.

Yes, i do push the tail out on secluded empty U turns.

Right, anyways.

my questions are these :

1) [COLOR="rgb(65, 105, 225)"]BRAKES[/COLOR]
i need brakes (discs,calipers, pumps) which will be able to hold up about 350 whp ..thing is , its still a 318ci .
what are my options, besides custom fabrication etc? I know a 330's rear wont go in coz of the brake shoe size diff.
which other bmw brake pumps / brakes will work for me?

2)[COLOR="rgb(65, 105, 225)"]LSD[/COLOR]
what can I do? what can go in? please explain rear subframe too. will an M3 rear subframe go in?

3)[COLOR="rgb(65, 105, 225)"]axles[/COLOR]
can i get the e46 M3 / 330ci axels in? (axels = bits coming out of diff that spins yer wheels.. we call em driveshafts over here)

Thanks in advance for all your forthcoming answers.

Pics!

engine shot is somewhere in december, before xmas, to prove she was running fine. a lot's been done since.

second pic is her a week back.

Dammit, now I want to pick up a 323 and do the same thing!

Wasn't sure if this was a troll thread or not. I'm sorry I ever doubted you, that's a serious swap

DO IT ! But the mod bug quickly gets out of hand it's really cheap to mod up to 500 whp on STOCK engine internals.

No worries chief. There are a few running around. Patrick Weismann has one onhttp://************.com/2010/07/car_...6_bmw_drifter/ , and there's a guy in Florida who's also done it to his 328.

S pee d hunt ers in there

First off, Im assuming the 318ci is the same body as all the other CIs?

Brakes: I would think you could change out the 330 brakes by changing everything on the wheel hub. Not sure since i have the 330 and never looked into it. (love me them brakes!)

Diff: There are LSD options out there but for $$$$. Not cheap. A M3 Diff does not direct swap but im not sure about the subframe.

Axel: the shafts are different part numbers but dont know if they swap out. If the M3 Sub-frame does fit then just do a whole rear end swap if not do a swap from a 330CI and you at least get the bigger brakes and shafts.

Oh, and as for the subframe itself (the actual metal of the chassis) you MUST reinforce it. E46s are notorious for cracking subframes even with smaller engines under DD loads. If you're chucking 350 whp at the back, you'll need to strengthen yours. Good luck, I'm looking forward to this build A LOT

THANK YOU SO MUCH!

Os Giken is available in Malaysia. Lotsa European and American companies refuse to ship to southeast asia due to fraud and scams. sigh.

Thanks mate. Since the car's been sent to the shop, i'll ask my mech to go source one and start the strengthening. We nearly got a toyota 4pot front on there the other day (330mm) but the knuckles weren't doable. oh well.

This is awesome!

Please tell me you left the 318Ci badge on?

Unfortunately, it was debadged before I acquired the car. That woulda made her the ultimate sleeper.

I think 330 rear brakes would require the trailing arms to be swapped

supra motor? where dey do dat at?

First off, really cool swap! Not something you see every day, that's for sure.

1. I would just do 330 front brakes, or better yet a good 'ol fashioned BBK. Stoptech, Brembo, etc.
2. Reinforcing is a good idea, and OS Giken or Quiafe is a safe bet. You're going to spend some $$ here, not that it presents an issue.
3. Have you been breaking or twisting yours? I would expect the driveshaft to go first on these cars.

A complete M3 rear end might not be a bad option, but you're still stuck with a relatively poor viscous LSD, and you have to swap everything. You'd end up with big brakes on the rear, though, lol. Probably need a custom driveshaft on a 318ci, too. There is some info in this thread.

M3 LSD is a multiclutch unit, not a viscous coupling. What you're thinking of is the shear pump which controls how strongly the clutches lockup. It builds up more pressure the greater the difference in wheel speed is. In an extreme enough situation, the M-differential can achieve 100% lock.

Thanks for the pointers, chief. Driveshaft isn't an issue. Will get a better custom bit done further on when the subframe is done. Hmm. Whatcha think about a reinforced 330 subframe and a quaife or wavetrac lsd?

Turner motorsports claim there's a viscous element to the m diff..this is probably what they meant..still..a bit overpriced, M..

Brand new it will of course be expensive - it is a BMW part afterall. But you should be able to get an entire M3 rear end pretty cheap from a wrecked car. That would also enable you to put in M3 rear brakes at the same time.

I'm not sure what those Supra motors rev to, but you can also swap the R&P with the one from an E39 M5 or E36 M3 for a less aggressive ratio if necessary (3.15:1 and 3.23:1 respectively). The LSD itself is the same style as the ones found in all modern M cars. There's a reason BMW has been using it in all of their cars - it is a good unit.

In fact, the entire E36 M3 diff should fit in the E46 M3 housing if you don't want the variable lock. They're both "210mm" style differentials. The diesel E46s have a 215mm diff case, which may be able to accomodate the E9x M3 differential (also a 215mm I believe) if acquiring diesel parts is any easier.
