R33 Rb30 Conversion

[N I B]

11-1.5 and 12-1.5. 1.25 tread is wrong.

quick question,

how to remove the timing belt gear from the crank? any tricks?

[VHR32]

Im just looking how to do that myself right now! Ive heated it up and got it to move a few mm.......

[r33_racer]

The most common trick is to just drill a few holes in it through the radius of the gear and tap it with ya knocko and presto it should just crack and slide off..apparently they are about 40 bux for a new one. Others have successfully gotten it off with about 2 cans of your choice of oil lub/peno spray eg..wd40, crc or inox and a rubber mallet.

You could always heat it up with an oxy and knock if off, but id be abit worried about how much heat you would need to put into it to get it off...noting that the heat will transfer into the crank as well.

[Craved]

will try to get the bearing puller onto it tomorrow, if i cant, off to get a new drill bit and give that way a go.

by knocko im guessing you mean slide hammer?

[Craved]

any thoughts on using the: ROSS 2 PIECE BILLET TUFFBOND BALANCER FOR RB20/RB25

apparently 4.1kg vs 6.2kg from factory

would they be suitable for the rb30 crank?

[StockyMcStock]

guys i thought i'd post up some pics for you of my new engine setup. have it running on the standard RB25DET base map now, and it runs a treat! boosts well, is great off-boost as well.

after a 100km run-in, i put the foot down a few times today on some nice straight stretches of road. to me, it feels like it's making over 200rwkw on 10psi. dyno figures to come later, when it gets tuned.

[Bl4cK32]

yer im running the rb25 base map too, and its ok.

Nice job, i asume the super charger isnt on yet?

Manifold....did you make that yourself? Just looks a little funky *no offence*

[StockyMcStock]

correct, ze blower is not on yet. running a GT40 with a 1.34 rear housing only at the moment. very laggy, but immense top-end power.

yep made it myself - the surface coating is peeling from the heat already it looks funky because i have to fit a supercharger in front of it.

As always impressed with your efforts stocky but You should really get it powdercoated or whatever it is they do to exhaust manifolds.

[Cubes]

Definitely hanging out for this one.

I can't wait to see an incar vid of the boost gauge and tacho/speed. You are going to take one?????????

[StockyMcStock]

haha yeah i'll take one.

i ran over my AFM today (long story, stupid cooler piping clamps!) but got a new one tonight so i need a bit of new piping. should have it going again by the weekend i reckon.

i'll see if i can take some in-car vids of it at the moment. it's hilarious to drive, you could boil an egg in the time it takes to hit boost, but when it gets to 5psi you better hold on! whackiest turbo setup ever.

hint: there will be two boost guages when it's finished mmmm twin boost sources

[ISL33P]

good stuff neil.

it is refreshing to see something built by the owner instead with some different ideas instead of the run of the mill stuff coming out of workshops.

[R31 POWER]

Fark yer thats madness!

I hope to join the 30det club soon.Should be picking up r32 rb25de head tomorrow and got a stock botton end to.I'm going to see how the current set up on the rb20det goes on it.

I'll be keeping the hks gt2535 on it what do you guys think it will go like with it?run out of puff in the top end?

Probably but you will see full boost very early with lots of low down power, should be very drivable and quick on the street.

[Bl4cK32]

its wont be very drivable. ive got a similar sized turbo, and it sucks balls.

boost is very early -1500rpm. boost is instant wheel spin, first gear is useless, and there is no top end. Any car with a half decent op end will just pull away as u curse having to change gear at 5500rpm.

get a gt30r or gt35r straight up and be done with it.

[Cubes]

The GT2535's on the rb25's tend to make 240rwkw so I think it will be half decent. It won't hold much power over 5500-6000rpm as to do so the rb30's really need a nice exhaust manifold.

But it will be awesome to drive none the less, instead of selecting second to accelerate hard out of a corner you will be selecting third.

[gimpyr33]

Has anyone else noticed that the front cylinder's pipe is very close to the breather rubber hose? Please don't burn down that commodore.

[StockyMcStock]

lol yeah i did notice that - it hasn't melted......... YET. i'm going to try and get some decent fittings brazed onto there some time soon. but so far it's doing okay?

oh yeah, for you guys doing this on a budget, the above engine was built entirely by me. the car never EVER saw the inside of a workshop. i built the bottom end myself, the head got redone at a shop before putting it together. the plenum is a custom job of course, but i did ALL the piping and made the exhaust manifold. i wired it up myself and installed everything myself too. the engine revs beatifully out to 6,500 and just wants to go further and further but i'm not game.

i might see if i can take a few vids of the boost guage and tacho this saturday night - it's hilarious how laggy it is. the car is about 3 times as fast in 2nd gear as it is in 1st because it doesn't make boost in 1st really! it doesn't wheelspin either because you're doing 80km/h before it really starts moving. 3rd gear is just scary - you'd need to be doing 120km/h before the turbo kicks in. overall, i love this engine so far. can't wait to get the M90 on there :eek:

[gimpyr33]

So far so crispy, i mean good... JK! Doing well.

So to run it in you take it to 6 grand, not how i'd do it but time will tell.
