ill ask for ya mate

[WRCVR4]

Shit, any ideas why ?

[S15ETA]

id say it shit a bearing and went through the block and breaking the rod and smashing the piston to bits, but i could be wrong......here some pics....one of whats left of the rod i pulled out of the block and the others of the hole just behind the turbo next to the gearbox......shit pics but u can just make it out

sorry to hear bud.
the streets will be quiet again with the beast off the road for a while.
well that makes 2 of us now with fried motors :S

Harry,

What about using a 4g64 block and bolt on your head?
You'll need new pistons and rods
Apart from that, factory crank and get squirters in.

Perfect for the street and track!

yeh i was thinkin bout that baz....dougmo says the block is taller than the 63.....so im wonderin how it would fit......like the mounts and height of the sump off the ground, the 63 sump hangs a bit low as it is stock.....but really the 2.4 would be the way to go with a fuk load of torque:cool:

Use the 4G63 block and a stroker crank/piston combination instead - straight bolt in when you look at the engine bay side of things and no stress.

You get 2.3 litres instead of 2.4 - but who's really going to notice? :confused:

Money wise, it would be cheaper to go a 2.4 block instead of trying to source and buy an evo 4-9 block. But that said a 4G63 with stroker crank and all that would be the go i reckon, if money isnt an issue.

i just took off the head, and fuk me! theres another hole on the other side of the block, the cyl wall has chunks missing and theres a bit of damage around the valves.....the head might be repairable i guess

[bazeng]

The height of the block only affects the top part of the motor so the sump etc will stay the same (deck height will change).

Also, as for 2.3L vs 2.4L, one benifit in 2.4L over 2.3L is a longer skirt piston which will reduce the amount of piston rock in comparison to the 2.3L short skirt pistons. The downside is the additional weight of the full sized piston in the 2.4L setup. But both are good.

As for cost, its pretty much the same for both setups. The only change would be machining for squirters if you go the 2.4L block. As for sourcing the block, what Jstyle says is true. It'll be easier / cheaper to find a 4g64 block over a used evo6-9 block. All the other costs incurred will be much of a muchness.

Either way, 2.3L or 2.4L they will both be better than the 2.0L overall in your application.

If you wanted to, go the 2.4L block / 2.0L crank some long rods and custom pistons. You'll be able to rev that mother out to 10k without any issues!! (they call this the 2.1L destroked motor). The only problem with this is trying to shift at 10,000rpm.

i spoke to adam he may have something

[S15ETA]

ah well......sweet! let me know polo, brother!!!

[NASI]

Well if your block is stuffed and head why not go for 2.6L stroker?

a 2.4L can still rev out to bloody high numbers it is just people are more scared to look at the APC kit they rev theres out to 9600 so you could rev it out to 7000 with no issues or even 8000 with no issues as long as you have the mods to do it safe eg headwork

[DOUGMO]

the 2.6 stroker kits are pretty exy, especially after the bock work has been done etc... the bc kits are over 5g now with the exchange rates.

still not a massive revver because of the rod ratio though but as you say 7g is fine

[S15ETA]

i think going 2.6 is a bit of an overkill and is very exxy......by the time u get a turbo to match it, ud have stupid power then its driveline $$$$, well thats my understanding of it.......for street/track 2.3 would be nice.......but the destroked 2.1 is very appealing......would u guys say it would behave like a 2l b4 8000rpm????

[bazeng]

if what would behave like a 2L?
the 2.1L?

the 2.1 will utilise longer rods and lighter pistons therefor you would get more torque than a 2.0L and also be able to rev it out alot more due to the improved rod ratio.

The rod ratio on:
2.1 destroked motor will be 1.84
2.0L which is 1.70
2.4L which is 1.5
1.6L using a 1.6L crank in a 2.4L block gives us a ratio of 2.13!!!! This thing will rev its guts out!! somebody build an NA one of these, it'll eat the honda's up!

Ideally, 1.5 and up is what we should aim for.

and example:

Honda's a considered to be high revving motors.
The B18C integra type r has a ratio of 1.58
The B16A's out of the type R civics have a 1.74

So all in all, although the stroker ratio's aren't that great, it's still not too bad!

a 2.6L based one 102mm stroke / 150mm rods (stock length) and shorter pistons will work out to be a ratio of: 1.47. This is where we go downhill.

Now if the 2.6L stroker had 102mm stroke with longer rods ie 162mm rods, we would have 1.58. This is ok but the position of the pins in the piston would not be ideal.

I'm guessing the 2.6L stoker would have 102mm stroker and 156mm rods with some sort of stroker style pistons which gives its a ratio of 1.52.

So it would still be ok.

Harry, I think the destroked 2.1L will be able to rev well beyond 10,000rpm safely. I honestly believe alot of so called 2.0L guys are either running a destroked 2.1L or if sticking with the 2.0L block, they are running a long red setup. Having the standard 2.0L combo rev to 10k+ would be difficult based on the weight of the piston. Unless of course they have super strong rods / crank.

Go the 2.3 or 2.4L Harry.
They are the most practical as rods will be off the shelf, so are the pistons.

[NASI]

i might sell my 2.4L stroker kit and go the 2.1 option i love to rev out think of a gt3076 on a 2.1L or even a gt3582 on a 2.1L

[S15ETA]

how much u gonna sell the stroker for rob?????.......shit mate, if u go 2.1 then u can run as bigger turbo as u like......like a 42r yeh???? well, thats if u wanna go down the drag strip.......

[evopwr]

sorry to hear the bad news about your engine harry; hopefully the evo will be on the road sooner then later!

also, massive LOL calling i2obert irobot in earlier posts!! hahahahahhaa!
