Bout time you started a thread on this.
You would have had quite a project thread if you had.

needs less turbos and more trumpets

[J-Calico]

damn,
i whole-heartidly(?) thought the sigma was gonig to be involved...
ha

But really this looks as though its going to get very interesting.
is '26 a 32 motor? going to do any refresh/maintainence on it?

[DJZ]

Needs 1 less turbo and no trumpets.

The motor has a knock, I bought it cheap. It's out of a R32, hopefully it won't be too rooted when I pull it apart, I've got an N1 oil pump for it and some ARP rod bolts. It will be getting new bearings but I don't really want to pull the head off or pull the pistons out, but we'll see what happens.

a v6 would pretty much make one of those mid-engined wouldn't it?

[mikuni]

So cool. Would be lol to retain the gearbox and front shafts, but yeah nah, don't do that.

Looking forward to this build. I would suggest doing a little bit more of a bottom end rebuild if it actually has a knock, because if its not a major yet, it probably will be if you just throw bearings at it then go back to boosting.

[k-trips]

Whatsthis?? You have a 320hp L28?
What are you doing with that motor??

[kyteler]

L28ET. DJZ is the man, refer to his avatar for further clarification.

[DJZ]

Yeah, the bottom end will be getting a bit more of a work over, the crank will need to be ground and the rod more than likely replaced, so I will probably just end up with another crank so I can stay with standard size bearings.

I'm investigating forged pistons and H/I beam rods but that's going to add $$ to the build.

L28 ended up getting split up which is a bit sad, I sold the bottom end and throttle bodies. I'll keep the head for the moment.

A VQ30 would end up pretty much inline with the strut towers, they are pretty awesome motors, my mate has a nearly standard one with a GT3540 that makes 430whp, it's going back for tuning in 2 weeks and will probably end up with 500+

[DJZ]

Oh and this was the L28 when it was running 278whp.

^^^ Zak-attack
Are cranks easily accessible? Pricey?

[k-trips]

Surely you can regrind it cheap enough - oversize bearing shells FTW!!

[DJZ]

Decreased surface area FTL

[k-trips]

Not necessary FTL cos there is less drag - well at least thats why circle track guys use small journal cranks..

Could also offset grind the journal and achieve a slightly longer stroke

[DJZ]

Yeah I don't think it's such a good idea doing it especially when RBs have a well known history of oil supply problems, anyway the crank will more than likely just be replaced with a standard one, looks like I can one for less than getting the rooted crank ground.

Looks like I've found some 2nd hand JE forged pistons and some Tomei Poncams for $1200.

[Damien!]

What HP figure will you be happy with?
Anything that'l beat Briceface?

[DJZ]

Well I'll be spending more on fixing the motor than I would like so will probably have to stick with the twins for a while, I've heard they are good for 400hp but I'd be happy with as much as the L series was making for the moment.

[Brock-Lee]

Mate was making 420whp @ ~20psi with stock twins out of an r33 motor. That was really starting to just blow hot air at those numbers

[Damien!]

Oh yeah, I did see the silicon everywhere.
Forgot to mention that.
