R33 Rb30 Conversion

[mr_rbman]

since Gav is showing off his motor i may aswell post up mine as i have just got mine back too, not quite as fancy as his though, hehe!

Just having a few problems with the oil and coolant lines on the VG30 due to the extra deck height but i guess that all the fun, will hopefully have it in the car and running sometime this xmas holidays!

Drop it in the rolla.

Tensioner bolting surface looks as it will do the trick rather well.. <picture saved>

[conan7772]

The cams have 9.0mm lift direct fits probably a bit of overkill for the rb20 but when everything comes on together is a good hit, should be nice in the RB30.

Where did you get your CP pistons from?

<{POST_SNAPBACK}>

TweakIt at Mona Vale, Sydney.

They're doing the build for me.

this is mine, although now the turbo is hi mounted on a 6BOOST manifold and has a CPC Plenum with 80mm throttle courtesy of ISL33P on these forums

engines are looking great guys - seems everyones getting theirs this time of the year.

Does anyone have a diagram of where the hell everythings supposed to go on the R33 plenum?

[SirRacer]

Are theese bearing numbers both big end like you have said, or is one a number for the mains(crank)?? If not what is the main bearings part number?

<{POST_SNAPBACK}>

sorry the bottom number is crank

[SirRacer]

does anyone know the biggest turbo that will fit on a stock manifold?

[conan7772]

Here's mine.

Not much to look at yet.

Next stop paint shop.

2BNVS,

Can you post a few close ups of the manifold.. It looks awesome.

[Cubes]

Platinum,

We will have to take eath other for a spin with once yours is in and running.

I'm keen to see the difference a higher diff ratio makes, I'm sure your also keen to see how mine drives with the 4.363:1, by the time you see it she will most probably have a 4.11 GTR mech shimmed center.

The VL being roughly the same weight as the R32 and the gearbox's having very similar ratio's it should be quite a decent comparison.

its a trust item and will fortunately be coming into my possession very soon

yeah no probs sounds like a plan. Just got to get this thing installed over the holidays, I seriously have no idea how the fark I'm going to hook this plenum up, I barely just had the VL one understood, this is like 50x more difficult.

whats actually got you stumped?

[platinum]

most of the coolent lines to be honest heh, it's okay I'm borrowing a diagram from someone now.

[Cubes]

Its easy pezy japanezy...

I need help re: injectors for my RB25DE head + RB25DE loom + RB20DET ECU.

I am thinking R32 GTR 440cc injectors might be suitable?

Will they drop into the same fuel rail? Will I need a resistor pack?

[Dahtone Racing]

use series 5 RX7 injectors the go straight in 550cc

you will need a resistor pack to use GTR injectors

[MarkE]

My understanding is that it is virtually impossible to tune RX7 Series 5 injectors with an RB20DET ECU.

[Cubes]

Martin Donnan hasn't had much luck with the RX7 squirters and the stock ecu. Bad idle.

Resistor pack isn't a hassle. R30 resistor pack ~6ohms, I've seen them as low as $5 (when they don't know what it is) and up to ~$30.

Works perfectly.

The RX7 injectors appear to work quite well with the PFC and the RB30DET.

Nice smooth idle and nice starting also.

reckon any of these would work/fit? Pretty cheap prices too
