hey just got to 2 questions

number 1

i wars thinking of making a rb20det with 500bhp to start with, becourse not many people have done it, and to see if it can be done. so if you have an idea to what parts i should use it who'd be great. i am going to use a HKS f-con v pro engine management.

number 2

is it even possible to run 2,2 bar of boost on stock internals, becourse there is a man in sweden that clams to run 550bhp and 2,2 bar of boost, here is the specks.

ported head with custom cams.valvs

stainless steel exh.manifold with T70 Turbo

700hp + turbokompressor.

HKS 60mm wastegate with screamer pipe

Jun style polished inlet manifold with 90mm billet trottle

Bosch 1000cc injectors

twin Whalbro fuelpumps

modified fuelsystem

GTR style large intercooler 3# pipes

Link Engine Managment system

water/methanol injected to support the 98oct std pump fuel

when going over 2 bar of boost

HKS ignition amplifier

Nos system

launch control/antilag system

sorry if my spelling is a bit off

Its pointless. A waste of money. It will be lag city like no tomorrow. Youd be better off going RB25. But if you want to do it, then do it.

2.2 Bar on a stock bottom end...you can try it, but dont expect it to last more than a couple of dyno runs!

Ive heard of someone running 2.0 Bar through an SR20. Its crazy!

here is a pretty crazy rb20 built by OHperformance i had on the dyno the other week the revlimit was 9800 and sounded sweet, real credit to the guys.... :) 490hp at the wheels.

it must be mental from 5000rpm to 6,000rpm!! lol it triples it's power in 1,000rpm! does it still make power after 7500rpm?

there is a reason not many people have 700hp turbos on RB20's... did some people go on school holidays early?

T70 turbo sounds like a piece of shit http://www.skylinesaustralia.com/forums/Eb...bo-t130247.html

5000rpm of lag does not sound like fun, IMO, if you want that power, RB30DET or a turbo LS1 :)

femno: i know that it is better going for a rb25 but here were i live they have some strict rules about engine swaps, the only way i can do it, is if the people that decide if it is going on the road or not, cant see the difference on the two engines.

They have strict rules about motor swaps...

Yet you can make the motor you have into a 500bhp item?

Sounds like laws there are dumber than here in Victoria, and i thought that wasn't possible.

500bhp would be about as useless as 1000bhp from a OS 3ltr :verymad:

Whats the use of the car? You would get far more enjoyment, speed and so on from a RB20 that has more response.

Such lag that would require would make the car slower

i am going to use the car as a every day car in the summer.

if i remove the cover over the plugs so they cant see on the cover if it is a rb20 or a rb25, but is there any other way they can see that it is a rb25, and not a rb20

If you buy an R33 RB25DET it is easy to pick the difference as the inlet cam gear looks completely different and the inlet manifold is clearly different. Get an R32 RB25DE and turbo it, nobody can tell the difference externally. I was going to put 25 internals in one for a cheater RB20 but am happy with the 340hp at the wheels my std RB20 makes so sold off the engine, rods, cams and pistons etc

300rwkw+ & RB20 in my book does not equal alright for a daily driver :P

250-270rwkw & RB20 IMO is about the limit, otherwise you just hurt resposne too much to enjoy it and you have to drive with your foot up the car everywhere you go

i Dont know Ash, 4 years ao people said anything more then a 2530 and 220rwkws was too much for a std RB20. A new manifold and some different turbo combos are getting thrown at Ben and we will soon know where we land, it will be between 260 and 310rwkws somewhere. Just have to find the combo that works best, cant wait to see if the std 20 can handle the extra power and more importantly revs :D

...walks off and starts singing "anything an RB25 can do, and RB20 can do better... :P

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
