Old news. Still sick though.

 

but this is all 4 parts. I thought only part 1 was out? When did I miss this?!?!

 

A while ago. Ive got the whole build book printed out, Have for 2 months?

 

OOPS< I'm an idiot, I thought you were talking about the Buld book, Not that.

 

That is not old news. It's the 300 HP LSJ build up. All 4 parts. It's a sweet read. I just finished looking at it this evening.

 

Sweet find!...thanks Tim

 

Yeah thanks!!!!!

 

I corrected myself, Thanks!

 

There, I fixed the title. That should help

 

Awesome find. I might use this one of these days.

 

definately sounds like the beginnings of a stage 3 kit...especially with the pulley they use that is smaller than the stage 2 pulley...just might be quiet an expensive kit...lol...its a thought though...i wonder how much those pistons can really take though. i know of alot of non forged pistoned engines making plenty over 300 hp...just curious

 

Nice find
I went looking for the last 3 articles the other day and couldn't find them

 

hey, y dont yo kill the spinning bmw symbol......it,s killing me. Whats a bimmer anyway?

 

Take a close look at the 4 part of the stage book. Anything over 230hp on the 2.0 LSJ needs better flowing injectors....this could be the reason why we are throwing lean codes. Just an FYI.

 

Thats a really good point there. hmmm

 

This gives me more reason to replace the stock injectors because we are throwing more air then fuel at the issue.

 

My BMW symbol stays unless Jonel tells me to take it off. And A Bimmer (pronounced BEE-MER) is Fan-speak FOR A BMW!

PS: My Name is Nate, Not Hey.

 

really good point...and im guessing they are talking 230 at the flywheel of course...but good point none the less...

 

I'm def thinking about doing this all. Not yet. Maybe after I get the whole IHE and stage kits. Looks like a fun winter project. Maybe next winter. Probably cost quite a bit as well.

 

indeed...im seriously looking into this, now i just gotta find a shop that will do it that i can trust...not enough time to do it on my own

 

The only problem I see on these build up's is
they seem to be using a 2.2. The 2.0 has most of these internal parts installed.

 

Thank You and take a bow
But please feel free to give credit where credit is due (or are YOU hosting these files??)

WOT

 

did u even read it??? it is painfully clear that theyre using the 2.0

 

.....please give me your opinion about doing the300+hp build. If upgrading the head on the 2.0 with the one listed in that bdwarr6's excel sheet says would the head already have the upgraded valve componets as described in the 300+hp build, seeing as it is an upgrade over what we have. The build says that our heads are good to 320hp and my plan is a bit higher still.
Also, in part 2 of the 300+ build it talks about the balancing shafts. It says that we lose 10hp spinning the stock ones and balance tubes cost some comfort. Can you explain the effect on the engine as well as the ride.
Your help is really appreciated.
Thank you,

*EDIT*
thanks WOT for the pm asnswering this question. I an adding it for others in case they are interested too.

Vic I'm not sure which head you are speaking about for sure, but the CNC ported head from the build book WILL WORK on the LSJ using different cams, but it might be better to just upgrade the LSJ head as it's actually the head recommended in the build book for the 1000-1400HP engines. The only weakness in the stock LSJ head is the valve springs, so if you upgraded them at least you should be good to 8000 rpm. It can be CNC ported as well, and would then be cheaper in the long run.

The balance shafs reduce tortional vibrations at lower engine speeds. So if you install the neutral shafts, the idle tends to be a bit rougher, with a bit more engine shake (not a big deal for a race car of course- but MAY be ibjectionable to some)
