Big Power RB30 Engine Build

[bernmc]

Sounds manic! Can't imagine what it must be like to drive - I've got 200BHP less and I think mine's out of this world !

Without wanting to restart the whole HICAS debate again, I'm not sure that it should be an automatic removal item (you certainly don't need the weight saving with all that torque ). Colin Hoad (CAT) commented that the GTR is still one the fastest cars exiting a corner ever - and I assume he's referring to a HICAS positive car. At Silverstone on Sat towards the end of the day, I was getting on the power earlier and earlier out of the bends and loving the feeling of the rear steering to line the car up...

Pupsi,

Have a look at the stoptech stuff, i have the 355 discs with 4 pots front and rear setup front and rear and they work brilliantly, brake ballance front to rear is perfect you stamp on the pedle and the car stops nice an evenly with no nose diving and no locking up even in the wet its very hard to get the abs to come in.

a mate has the AP Racing kit front and rear on his GTR they are 6 pot front and 4 pot rear from memory and he preffers my stoptech brake setup as it is more balanced.

have a look at the stoptech site in the us as they explain their thoery behind the stoptech stuff.

Very good on the road heat up quickly and dont fade. not sure about on the track, the ap stuff is very good still good on road but did fade at silverstone when i was out in my mates car, but that was under extreme use!

as for tyres i run falkens and a pretty good all round tyre but when i replace them i will try something a bit more toward a road legal semi slick.

My mate runs the avon road legal semi slick and is not overly impressed with them, not great grip on track in the dry, ok on the road but noisy when cold and obviosly crap in the wet

Car sounds awesome pupsi! Well done

I will be looking into the Stoptech brake set-up, there is a few different sizes available, which size is it best to stick to for the 33.
Also having a little problem with the oil pressure, from cold start my Defi oil pressure gauge shows 8bar, once warmed up or shall i say hot it show's 4bar, which I have been told is too high. So both Rob's (RIPs)+(Tweenierob) have decided the way to go is to fit an oil resrictor in the oil line and see what results that brings, dropping the car off to Tweenierob tomorrow evening and picking it up on Tuesday evening.
Where can I get some graphics made. If any of you guy's can remember the Pepperami advert on TV, I'me after a little graphic of the Pepperami guy and the slogan saying A bit of an Animal. Think that would sum up my car to the TEE.

[Stachi]

Cool idea for graphics! Show us some pics of your brake setup when you've got it. I worried about my new wheels, they clear the stock brake calipers on front by only 5mm
But I too want the Stoptech brakes..

I also run stoptech 355's. Great stopping power.

Do you have them on the front only or all round??

Front only

[pupsi]

On the suspension side, would upgrading the sway bars/anti-roll bars, be a good idea or is there something else which should be looked at first?? if so, in what order should the mods be done in?? 1st, 2nd, etc, etc??

Pupsi,

On the brake front, you can't get a lot better than the 355mm (monoblock) 6 pot Alcons at the same price (if not cheaper) as either the Stoptechs or the AP's. The discs are reputedly far better and they are British made , not to mention the obvious advantages of an F1 proven monoblock manufacturer. I put them on my R33 GTR at the beginning of the summer and - very happy with them.

A quick update. The turbo is passing a lot of oil through it, so its back with Rob (Tweenierob) and in the process of fitting an oil restrictor in the turbo oil line to see if that helps. If the turbo is not already f***ed. If it is, then its onwards to a GT42. The Jun oil pump is a monster, I get 8bar of pressure from a cold start. Warmed up its 4bar.

ref oil pressure,
hi pupsi, i get alot of oil pressure too and after looking in to it,because there is no oil squirters in th 30,s then less pressure is lost so more pressure is made.. ref oil feed.
this is always an rb30 problem, my gt4094r has a restrictor fitted actually in the turbo, i would have though your garrett would have too?.

[R.I.P.S NZ]

It did have a restrictor in it and its the same as every other one we have ever done so Tweenie and I are unsure of the cause at this stage, but whatever it is it'll be sorted.

Rob

[tweenierob]

I'm happy with the cause, easy fix.
