R33 Rb30 Conversion

[R31HOOCH]

Can the pistons or bore be changed to achieve a more suitable compression ratio???

[R31Nismoid]

Obviously you have not read even one page of this thread...

[R31HOOCH]

Yeah i have read some... Its just that its so damn big, there's so many different conversations about what i wanna know its all just a little confusing... Basically, i've got a perfectly good RB30ET block with f**k all km's on it, im planning on puttin the R32 RB25DE head on it with all aftermarket bolt on's... I just wanna know whether the E and ET blocks are basically the same and whether i just need to use the RB30E spec pistons to get the appropriate compression ratio??? If not, what would be best???

[r33_racer]

Get the guide, it explains virtually everything you need to know mate.

[Guilt-Toy]

If you are thinking about putting the head straight onto the rb30et block standard then it wont work. HOWEVER if you change the pistons to the NA spec then it will be ok.

The pistons in the rb30et are too low compression and the NA pistons should be used.

If you rebuild the rb30et block and put forged pistons in it to raise the compression up to the same for NA then it will be good.

Guys the RB30 vented coil pack covers are going to be cut soon any suggestions as to what is going to be on there would be great i have come up with at least a few say 2 or maybe 3.

"RB30 DET"

"RB30 DOHC"

"RB30 TWIN CAM TURBO"

"RB30 GODZILLA" for 4wd ones

"RB30 TORQUE MONSTA"

[paulr33]

GOT GATE?

[r33_racer]

I must be slow....i dont get it?

I would have thought maybe GOT TORQUE?

"RB30 TWIN CAM TURBO"

"RB30 GODZILLA" for 4wd ones

"RB30 TORQUE MONSTA"

Maybe a "RB30 DOHC TURBO"

or " NISSAN 3000cc DOHC TURBO"

What did it say on the stock RB20/25 covers before?

[FORZA-MOTORSPORT]

On the rb25 Says "Twin Cam 24 Valve 2500 NISSAN"

We have now cut RB30DET AND RB30DOHC

Now im leaning towards either "RB30 TWIN CAM TURBO" or lukits01 "RB30 DOHC TURBO"

[Sydneykid]

Mine needs to say;

Twin Cam 24 Valve 3100 NISSAN

cheers

r32 rb25de head stock with det valve springs big front facing plenum 80mm throttle body q45 afm. bottom end stockish rebuilt. shot peineed rods, and aftermarket rings, crank collar, either rb25 oil pump or n1

what would this turbo go like on it?

called a gt45

Inlet (Exducer/Hot Side) T-4 Flange 70.1mm x 82.55mm (2.76" x3.25").

*A/R 1.05 Exducer

*A/R 0.66 Compressor

*Cooling/Lubrication Oil

*Outlet (exducer/hot side) 4.25" V-Band

*Inlet (compressor/cold side) 109mm (4.25")

*Outlet (compressor/cold side) 86mm (3.38")

*Compressor major diameter 98 mm

my goal is 400-500rwhp. On a 20det modded manifold When would this size turbo start spooling and when would it hit full boost? 15psi. unsure of what exhaust manifold yet, either a 20det stock modded to fit the t4 flange or a whole custom mild steel one.

Can anyone help with some info on this? is this turbo 2 big?

Thanks

Too big, by a long way.

cheers

PS; Shot peening used RB30 rods achieves almost nothing, spend the money on a set of ARP rod bolts

mine says RB30 TWIN CAM 24VALVE

very nice mate. Carbon Fibre touch really makes it look good.

[Adriano]

where do you get the carbon fibre ones, how much?

[Dahtone Racing]

i got my stock covers coated

cost me $500 for the 4 covers

how about "hey mr. policeman, i want a defect"

[FORZA-MOTORSPORT]

how about "hey mr. policeman, i want a defect"

HEHE no

"I HATE cops"

Another thought

"GTR EATER"

[lukits01]

How about

"Torque * RPM = POWA!"
