2.8 Options

[icydude]

I have been looking into 2.8L kits and it seems to be slightly slim for choices.

The tomei kit is not a full counter so i have ruled that out.

The hks step 3 is the only one that i am highly considering for 2.8's

Now i had a question as to how would the Nismo 2.8 gt crank hold up in a high hp application.

I have been reading about a company who ran the stock crank in a 1000hp car and did well over 44 dyno pulls and numerous 1/4 mile runs. This makes me think that the 2.8 gt crank would be as strong as or stonger but i have not seen it being used.

I have also been looking at the trust 2.7 full counter kit and the tomei 2.7 full counter.

I will not go OS 3L

Any help would be great.

So what do you want exactly?

[Beer Baron]

unless you want massive power then you are setting your criteria far too high. a step 1 or 2 HKS kit will hold plenty of power. It's only if you want the massive revs and massive power that you need even consider the step 3 kit. The tomei 2.8 kit is also fine for most hard core street/strip cars. In japan at the moment it seems the HKS kit has the slight edge on popularity though. They are both around the same price, and in my eyes good value.

as stated what is the purpose of the engine?!

stock crank and rods can handle 800hp (while given not indefinitly!), so any of the aftermarket cranks you mention should be fine. the step 2 HKS kit is ~800 rated, and as this rating is very much more than likely conservative, im sure if your building a street car that it will handle 1000.

Either way it sounds like fun, my HKS step 2 is nearly done!

I guess i should have worded that better my bad.

I am wondering what other kits are available and if anyone knows wha tthe nismo 2.8l gt crank can take power wise.

Crower's 2.9l will be out shortly in the new year.

I don't know if Apexi is still producing the 2.9L

The build will be tracked at around 1200 bhp and ran around 800bhp most of the time.

sly33 whats involved with the hks step2? i am considering going a tomei 2.8 on my rb25. just 8,500 seems a tad expensive..

[rev210]

The crower cranks will be very nice I'd imagine, and probably not to pricey for what you get.

77.7 mm stroke full fcounter forged crank, H beam 119.5mm rods and 87 mm pistons

[700HP-GTR33]

For the money.....

Would it not be wiser to spend it on a 3L bottom end , a set of oversized forged pistons,cams and

a decent head port?

I Find these kits to expensive.

What modes do you have and what power figures are you looking at?

[700HP-GTR33]

Sorry did not read your post and the fact you don't want to go 3L and over sized... .

But still waht modes do you have?

[icydude]

I wouldnt mind going with an rb30 holden block but the problem is they run for about 3500 aud here in Canada in somewhat iffy condition.

It will be 90% track 10% weekend car.

[Bass Junky]

Farkin.

Here they are like $150!

[700HP-GTR33]

Farkin alright....some-one buy him one and send it over to the South Park victims.....

And this is why you did not want to go 3L with oversize?

That is the most logical choice in Australia.

[icydude]

The os gliken 3l is over priced imo.

and the rb30 is not cheap and i know very little about it.

of course an hks kit isn't cheap by any means either.

[pnblight]

have you concidered the Jun 2.7 kit full counter balanced

[bubba]

The problem with the RB30 blocks is that unless you spend big dollars on a decent crank, they will explode at around 7500rpm.. my mate has a twinturbo twincam RB30 which he is pulling out to replace with a HKS Rb26/28 stroker.. so he can rev it to 10000rpm

[SLY33]

i love Rb26 stroker kit threads

Once i get mine running ill let you know if i can "feel" the dollars spent in terms of smoothness and response etc

Theres a few 2.7 2.8's running on this board, would be good to hear from.

u dont need to rev them (rb30) out to make big power, as they make the same power as other kits at lower rpm. plus u cant go expecting to rev a standard crank to nything near 10k like u could do with say a HKS, caus the HKS is full counter-forged, its like comparing apples and oranges

my rb30 is pretty much finished, im just waiting on the sump and my adapter plate to be ready (i've made my own adapter plate)

[bubba]

to make big torque or big power? as horsepower is a function of torque and revs, then yes more revs = more power..

and what exactly is "counter-forged"? do you mean they are forged and counter-balanced?

torque wins races, horsepower sells cars ...no1 wants a big power street driven car that when they smack the go pedal they gotta wait 6000rpm to go anywhere

and yes, i was being lazy
