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.

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...

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

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 :D

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 :D

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 :blush:

    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 馃槀 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
