Forge Internals?

[muchogarcia34]

So I've been gathering bolt on parts for the last couple of months to eventually install on my 34. I'm looking at making around about 250rwkw and not much more.

The bolt ons I've aquired so far are :

Plazmaman Plenum + TB

6Boost

GT3076 .82 External Gate

Turbosmart 50mm External Gate

Sard 650cc Injectors

FMIC

Koyo Rad

and some more that I've probably forgotten and more still to order.

Anyways, I'm coming into some extra money and am leaning toward forging the internals of the RB. But I see alot of people here are making this sort of power with no forging at all. How much can the RB handle? And also what is a forged good set up that I could possibly look at?

Any input would be much appreciated. Thanks.

To be honest forged internals for that sort of power really arent needed. I've read about way too many people going the forged internals route only to find out the engine was remade with a tin opener, definetly not a good one for resale value either.

general consensus is 270-280rwkw is the safe reliable limit. lots of people pushing 300rwkw with no problems tho. its different for every motor and setup.

17-18psi should do the trick

That is a fairly expensive list of bolt on's for something the stock parts could achive in pretty much the same scenario...

3076 will do 300rwkw, so you have the wrong turbo, 3071 is what you want for that power.

Or just a stock turbo with a hi-flow would be even better... but wouldnt make use of all your shiny parts...

lol @ 250...

you are gonna make 300rwkw with that setup.... just do it and enjoy it... if it happens to blow up, then forge it...

SHOULD make 300, doesnt always happen. I was dead certain i was with a similar setup, got rather dissapointed when it made 250, but at the end of the day its just a number

[muchogarcia34]

My aim is 250, if it goes a bit higher with these mods I'm not going to be dissapointed. I mean the engine is out of the car now, and i've lost my licence for 3 months thanks to loss of demerits, so thats why I'm sort of leaning toward forging. I just want to make sure it's reliable and I'm not gonna be thinking the bottom end is gonna blow on me everytime I start it.

If the safe reliable limit is 270-280kw I think I'll lean toward forging to be on the safe side, alot less hassles for later on if something does go bang

Does anyone have any idea on any good brands or set ups for forging? I'm not too sure of any really and what sort of prices I could be looking at.

All of your help and input is great. Thanks guys

if its already out of the car then chuck a low km rb30 block on there

[joeyjoejoejuniorshabadoo]

low km as in 300,000?

if that setup only made 250 it'd have to be a very bad tuner or a very tired motor....

expect don't expect much change from 10k for a decent build...

[JonnoHR31]

tune was a bit too safe but not bad. tuning it myself now but havent had it back on the dyno yet. was 17psi through an internal gate gt3076 .82 on stock manifold. look at the graph the difference between high boost (17psi) and low boost (12psi) was huge in the midrange but only 60hp up top, with the high boost dropping off hard after 6500. suggests too much restriction on the exhaust side. been looking at making a new dump but finding it difficult to find any pipe and bends larger than 3" that doesnt cost a small fortune

30's arent even run in properly until 500 000
