r30 skylines

[Crimmo]

rsx84: I haven't bolted the cusco down properly yet, but it looks like sweet f***all!

Don't know about r33 calipers fitting, im not sure if the mounts are the same, and they are bigger also. Also be aware that most wheels dont fit on after this conversion, i have 20mm bolt on spacers

I have a vg30 on the rb20, and i have a vg30 turbo on my rb25 in the r33 i had, they work a treat, only a small difference on the rb25 tho

[Ghostrider]

Crimmo,

I only want the VG30 turbo for emissions and engineering, then it's off and on goes a Garrett GT35/40, FMIC, 272 cams, 550 injectors etc, etc.

[Ghostrider]

R33 and DR30 callipers have the same mount spacing 100 mm (4 inch), prior models like R31 and MR30 have 3.5 inch spacings.

For a 4 spot conversion it is much easier to have DR front struts.

[Ghostrider]

I'm looking for an RB25 stock exhaust manifold as well, if anybody knows of one.

RB25 Turbo Manifold

[Crimmo]

Ghostrider: should be a bit crazy in an r30, what driveline will you be using?

[Mike Cash]

hmmm no go on the sensor thing...thinking the timing is out

hoping anyways....

anyone got a workshop manual for an rb20?

oh and anyone wanna buy a vg30 turbo....?

how convenient, im looking for one at the moment. hows the condition on that

sucker? and what you askin?

crimmo: try InjectMaz for wiring. i know he's done a 30 to rb20 before and he can often beat or match prices but the best thing, he can come to you if you ask nice. pretty cheap for cash too...

also, im still in the dark with these calipers... should i get em and try, i mean if they dont fit, they can be made to fit without too much hassle, so it wont be a total waste? oh yeah, crimmo, what discs you using at the back?

anyone know the size of dr30 rear discs, the DBA thing lists something like 258 but apparaently thats wrong...

Initially, an RB20DET/HR31 gearbox and final drive 4.1:1 R200 Mechanical LSD with Cusco centre, approx 70/75 lb pre load, mainly due to having the Jenesis 260 kph Speedo.

If it doesn't handle the power, which I am expecting to be the case, I have an R33 GTS 25t gearbox as backup, but with this gearbox comes a couple of minor problems, the most primary being it's speedo drive; IT'S ELECTRONIC and am yet to work out how I can convert the electronic drive to an analogue speedo. If it can't be done I will get an electronic dash cluster assembly and sell off the 260 Jenesis Speedo.

[Ghostrider]

DR rear are same as Z31. 290 x 10, but you will need DR rear trailing arms for them to be bolt on.

As for the front calliper mounts, I was told by mates in Adelaide that MR are about 88 mm spacings, mount bolts centre to centre, where DR's are 100 mm centres.

Mike, send me an email or private message and I will put you in touch with a guy in Adelaide that has done it already, or at least looked at it.

[Ghostrider]

MR & DR front callipers are NOT interchangeable, they are different mount centres and the DR calliper is bigger and has to go around a disc rotor over 20 mm larger in dia. and 4 mm thicker

so end of the day:

is there any other way to fit 32 33 Z32 etc brakes to a hr30 2 door jap import without hr31 struts?

[Ghostrider]

Anything is possible. Just that DR30 not HR31 struts would make it a whole lot easier.

A fair bit of fabrication is needed otherwise.

if you use the speedo cable from the gtr its not electronic and has been used by a few r31 boys with the same problem!!

[tomj]

Anyone ever done it the hard way?

What would be involved in doing it

[Ghostrider]

Don't have a problem getting a cable, my problem is an R33 GTS25t gearbox uses an ELECTRONIC DRIVE for the instruments, but have got a way around it I think.

Will get back to you if it works.

I got your drift!

Bit slow today.

You mean use the drive assembly from the GTR, to convert back to cable.

I try.

[rsx84]

bingo! i should of used a few more discriptive words in the post!

[stu_r30]

looking at 3 hundy for the vg30 turbo.

bought it looking for big power....no just want to get my shitbox going so need the cash

nothing wrong with it, even went to the trouble of buying new banjo bolts for it.

i mounted it up to my manifold, fitted like a franger, didnt have the right outlet elbow tho

pm me if anyone is interested.

as for the workshop manual its ok im going to buy one to sort it all out, thanks tho.

Hi guys-thought I may be able to assist a bit.As you know,the DR30 has bigger brakes than the HR30,so diferent mounting holes,etc.I've had no experiance with MR30's,but believe them to be close(or same) as HR30.

DR30's have the 100mm mount hole spacing.HR31's(Japanese Skyline) also have 100mm spacing.

R31's(ausie) have smaller spacing,same as HR/MR30's.

R31(aussie) GTS have same struts/mounts as HR31's.

Type m and GTR 4 pot calipers have 100mm spacing.

Hope this helps (somewhat)
