we have a custom paint shop, dyno pack rolling road, full engine build shop ect ect, so keeping the car running wouldn't be a problem to be honest.

So you have the cash, "the paint shop", the dyno, "full engine build shop" etc, yet you have no f**king idea how to build this engine thats not the right one for the job anyway?

I should move over there and set up shop methinks.

EDIT: just saw you went the right engine afterall. well done

350bhp with responce would be ace.

SR20DET with GT2530, 230-240rwkw (~350hp at engine) with *awesome* response

easy :)

good to see you went the right way and got the sr20 heh.. if your adventurous and have the money, which it seems you do, you can get the TOMEI SR stroker kit and stroke it to 2.4L - then run a GT2835 for even more power with around the same response as the first setup with the GT2530

edit: for more info, head off onto one of the silvia forums, besides ns.com :)

I've decided to do the RB20DET, not RB24 it, going to spend alot less, down to the fact this has to be a car for the company not just for drifting, i still have my other RS13 which is a drift car so it don't matter if this is not as good. Its more the trick factor.

I need a GTR style Plenum? any ideas were i could get something like that?

Yeah go a s15 front cut conversion like JMS in australia have done.

The SR's are proven too produce the goods and they are still within the weight/handeling capabilities of the cars supension systems.

A full blown sr will munch the RB at drift duties.It has a better flowing head,alloy block! Put quite simply it is a modern engine where as,sorry to say this guys,an RB20 is vitually a dinosour.

If you had an R32 then it would be a different story id say.Then you would start looking at Rb25's/26's.

You will want a light nimble car with loads of on tap power to burn on call mid way through a corner.

What sort of gearbox have you chosen for the car.Custom ratios all the way baby.

As i say the engine has been moved back into the bulk head so it should be very good. As for suspention i'm running on Coil overs so spring rates are interchangable.

Its goign to be built up with TD06 20G now anyways, started ordering th parts yesterday.

THE thing i need the most, is a custom intake plenum? does anyone know were i can get one from, i have money waiting!

unique autosports in sydney <--click here.             

          OR

subzero in brisbane.

Please tell me i'm wrong on this, but looking at there RB20/RB25 half plenum (no runners)

skyplazplenum2.jpg

Don't the RB20DET runners have the back two out of line??? so this wouldn't fit. do RB20 and RB25 stuff fit the same to the head?

I mean do i have to buy this then find a RB25 runners?

Edited by superclarkey

let me start by saying nice choice, i am a bit of a fan of the rb24 and will be building one in the near future, BUT like sydney kid stated i think your goals are a little off for starters are you after 500bhp or 500rwhp (as you stated 500bhp at the hubs?) as there is a big difference and i think both are a little high for what you NEED to go drifting (drifting isn't ruled by hp) i think a figure more like 400 to 450bhp or 340 to 380rwhp would serve you well and should be able to be gain with decent responce. The first turbo that comes to mind is the GT3071R as featured on the ATP web site on a 2.4 litre motor making 400bhp and full boost by 3000rpm

http://www.atpturbo.com/root/releases/release051404.htm

with the motor your building you might even get away with the GT3076R

As for the motor configuration i know your got the money to throw at it but it really doesn't need alot of big dollar engine parts to do what you want reliable.

New R34GTR Crank $1100 aud (good to 10,000rpm and seen 900bhp+)

New N1 oil pump $560 aud

GTR rods with new arp rod bolts (again seen run 800bhp+)

Tomei forged rb24 piston

Tomei gasket kit

Nismo main bearing

Nismo big end bearing

Solid lifter kit

Cams 260deg 10.25mm and adj cam wheels

600cc injectors

Nismo fuel pump for gtr

APEXI pfc and avcr

Z32 afm

gtr intercooler (i would not go big as its not need and would only hinder responce)

Greddy 48mm radiator

oil cooler with relocator(brand etc doesnt really matter)

you'll need to do some nice custom work aswell

exhaust

plenum

head porting

obviously you can buy nicer name brand gear but i just stated what i think you need to achieve your goals and the let over money might be wiser to be invested in suspension, diff, gearbox, brakes, cage etc the gear you really need to be a good drift car.

Lol, Its a case i know what i want to do with the engine, but i've got to convince the person thats funding me to also want to do it. I'm defo doing RB20DET at the moment, i picked up the crank yesterday from Abbey, New GTR34 Crank paid for out of my own pocket, because of the time scale to get this car ready for its car show at the NEC birmingham in Jan, something must be kept simple.

pnblight thats a nice spec and something i was very much looking at. I wanted a GT3071R turbo from ARP but i can't afford it under budget at the moment, so Greddy TD06-20G is were its at.

unique autosports in sydney (just contacted them they do not sell plenum for the RB20DET, RB25 only)

OR

subzero in brisbane. : can someone help me find a contact please for subzero as i can't find a website for them.

The plenum is the most import item at the moment, the engine will not fit without it, so please help me track one down.

MAny thanx

    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
