Hello

I am ready to begin saving to buy a bigger turbo for my R32 GTS-T.

I asked a few months ago and I was suggest to try hi flow with Hyper Gear or similar company, GTRS, or one of the new Garrett turbos(dont remember which one).

My goal is 400hp. I want a responsive street car that will go on the highway and sometimes go to the track(no racing). But street car is the main.

Is it still a good choice to go with hi flowing a rb20 or rb25 turbo? Or should I look at something else?

Something else.

a lot has changed in the last few months of turbo tech for bolt on 20 year old engines. ..

Oh wait. No. That hasn't happened. And won't.

Meaning for the exact same reasons a Hypergear hi flow was recommend it is still the best option for you.

Street car, responsive and RB20 in the same phrase doesn't really get along.

I'm far from 400hp on my 20 and the car is not user friendly on the streets nor responsive for daily driving. Getting a better turbo could help but it won't make miracles. On track though there is no problem of responsiveness, but still far from 400 hp.

Good thing is, you can lend the keys to a person who never go above 4000 rpm without sweating. lol

Smaller HP goal, lower responsiveness goal or bigger capacity engine for street use with a 20.

HKS2530, GT2860RS, the smallest Hypergear hi-flow unit.

You may try an EFR 6258 if you can get a T3 flange welded on the housing.

All these turbo could be called responsive on a 20 for street use and will yield 220rwkw give or take.

Any bigger than this and you will degrade the fun on the streets.

Thank you.

I was waiting till I was ready for the stage of saving up to buy the turbo before asking more questions.

I will start saving now.

There are only 3 realistic options for an RB20 according to the 1998 issue of Hyper-rev

1. 350hp or less (response) 2530 or similar

2. 350 to 400hp (kills the entire bottom end) Trust TD-06 or similar

3. Increase displacement (RB2.2, RB2.3, RB2.4, or RB25)

They reached these conclusions 15 years ago; very little has changed today.

Lose some weight, you'll go faster.

Making 400hp & response from a RB20DET is not going to be cheap.

Making 400hp & response from a RB25DET is more cost effective and you'll spend less time & money.

More money for hookers & cocaine.

But then the tax costs more in Japan or some crap. That's his excuse anyway.

Which I find hard to believe. Why did Nissan bin the rb20?

IMO its a waste of time and money going to a 25 if you want 400hp when a bolt on 20G setup gets you there and is cheap, reliable and frankly my car was awesome fun like this for close to 10 years.

      S1 rb25/s14 starting problem

      By Dose Pipe Sutututu · Posted

      When you crank your car, and hit it with a timing light, can you see a steady crank timing?

      Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov

      yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
