6.0 L L98 Swap Into R33 - Rb26/30 On Stand

[GTR_JOEY]

Man I love those cam & tune packages that add 100rwkw they are just the bomb!

It's just a pity they don't exist!

Dunno what mean by they don't exist cause they sure as hell did when I got mine done.

Stock vx clubby 255kw at the fly. Made around 190 atw

In went OTR CAI, mafless tune, cam, 228 duration ( can't remember LSA, 112 or something) exhaust was already done though headers wernt ideal and had standard cats

Made 285 rwkw out of an LS1 with 130,000 km

Pretty sure it can be done.

Happy dyno's in my opinion - I've tuned countless ls1 ls2 l98 all the way up to ls7 with varying sizes of cams and I've never seen that kind of power on our dyno. I've made upward of 350rwkw but it's always been with cubes (427) and large cams 238@50 and beyond.

STD ls2 auto with exh and tune will make around the 230-240rwkw mark with a cai and similar size cam 225@50 you will only see around the 280rwkw mark with low rpm torque loss!

I tend to agree,

Most Cam/Spring/exhaust LS1's I have seen make 280-290 and depending what cam are lopey as hell

L98's have much better heads though (bigger ports and valves than an LS2) So 300+ isnt out of the question imo

[bubba]

Happy dynos aside, if they run it up before and after and there is a 90-100kW difference, that's all that matters.. not the actual final figure.

[jet_r31]

my mates ls1 ute has a tune/exhaust/spring/ otr/ cam in the upper 230's at .50, it makes 270rwkw through a auto.

other mate has a vx with a l98 conversion, with same stuff but a 237/242 cam it makes 330rwkw on a mainline with a manual.

for the dollar spent compared to the old stuff they are great!

cheers

Reguardless, I have to admitt the LS engines sound tuff as fu$k with those big cams and a free flowing exhaust in them

And the idle mmmmmmmm orgasmic

They do have larger ports and valves but I've never really noticed any difference in power out of the box and they seem to respond the same amount once cammed as well. Its all about port velocity just ask nathan higgan what he does with the heads. Aspirated performance isn't about bigger is better - unless your talking about cubes!

PS - everybody's got a mate with LS that makes a sqillion hp. I just find it funny that cars I've tuned with similar mods to other cars but with 50rwkw less seem to keep up!

hah the V8 guys love a happy dyno...seen a few where MAFless LS1's with a cat back making 250+

I grew up around 4V clevelands...bigger definitely isnt better.....

[jet_r31]

The only dyno i care about is black and 400m long ..it never lies!

cheers

It sometimes does lol

I knew a guy with a 33 R with ~1000hp....barely ran a 12 at bugger all mph

Mega Lag FTL

[jet_r31]

maybe it didn't make 1000hp haha

cheers

Just use what you have

do it! there is a reason nissan went from the vq30tt to a vk45de in there gt500 car, and in gt1. sounds like arse but goes great. no lag, flat torque curve. and it will do 100k befor any rebuild is needed. t56 box is also tough as nails. abit slow shifting but strong.

also whats the go with engineering these days?

[T04GTR]

throw a double row timing chain at it. when i was with the ute team, we started snapping timing chains very regularly.

[DVS JEZ]

Ive seen 245kw jump to 346kw with a cam upgrade. Thats with a maf tune

[045HOW]

If you can pull it off, go for it. sounds good.

No Replacement for Displacement.

Price of engine Sounds so dodgy..

P.s i have nothing against the V8 Swap...apart from it being a dirty ChevGM motor lol

[Raysboostin]

its goin to cost ALOT of money for this conversion unless u can do the fab work yourself, but dont get discouraged as the benefits are worth the effort. the simpicity of an NA V8 means alot less stuff to go wrong and so much torque everywhere!

Couldn't agree more!

You did find a good deal but not a good swap.

Not if you have a rb25det under the hood.

Cheaper power is not always better.
