Kinugawa Turbo Internal Gate Quality

[Roy]

Sorry... EBC. What brand?

[XRATED]

Looking into getting a kando turbo and recall int he past the internal gates where prone to spiking.

I have heard recently that the issue has been resolved. is this true?

or am i better off spending the extra on an external gate setup

For the sake of simplicity, fitting a stock replacement/highflow is by far the easiest option... a few hours, bam done! Hyper gear is a good way to go, I'm sure Sato can build you something to suit your application...

Being an Na engine, there is something to be said for potentially lower back pressure and egt's that can be achieved with the right external gate and turbo for the same power.

If you go a kando, you have to fabricate new pipe work and exhaust, so you might as well go external gate too... I haven't seen an internal gate kando work well n any set up I've seen yet.

Either way, it's going to be hard to get a much better set up for the street with a stock rb20det and an op6 rb25 turbo. If you want more for the track or a bit of fun, have a decent nitrous kit fitted and tuned for the same money.... another 70rwkw and less lag

Yeah i suppose it already makes more power than expected considering the fairly basic setup.

old dyno sheet below, made about 10kW or so more and everything ~200rpm earlier with the tune (coilpacks and slight map fiddle) last week on the same dyno.

realistically it is enough power for what i need. But we always want more
especially if i can maintain similar response

[XRATED]

Do you want more power or go faster?

I love rb20's with the best of them, but given the age and it's de of, I think you're right on the money at a reasonably easy 210rwkw.

To get more power with same or similar response will almost certainly create more exhaust back pressure and higher egt's which is bad news for your de valves and pistons as compared to a det.

By the time you are make enough more power to out weight the increased lag of a larger turbo, you'll be leaning on the de a bit too hard. A nice flat curve 210rwkw rb20 will in most instances just as quick as a 260rwkw rb20 on the street... on average, it's probably quicker up to legal speed limits.

Add to that, the couple of grand it will cost to go external.... you could find a stagea neo and sell your current set up to fund a high flow.

I bought a kinugawa td05 18g 8cm yet to be installed.when i bought it it took about 3 weeks to receive as the dude told me he was going to machine the wastegate port to resolve the issues.it looks like an awesome turbo.will be installing in about a month but if u want any specific pics of it let me know.cheers.

^^they are a good value-for-money turbo, I would certainly agree there. Mine has been on about 18 months... still in very good order

the 2nd lot of porting I did

I probably should have left more of a lip to funnel flow into the wastegate rather than smoothing it into the turbine, but, bit late now.

definitely some food for thought. i priced up the cost of going Neo with similar mods that i have now

$1600 motor

$900 nistune + tune

$500 splitfires

total = $3000 or so for very similar power (based of my mates rwd RB25 neo stagea thats stock ish + tune)

to ge more power add

$1000 turbo

$500 injectors

etc...

which is why i thought just adding a turbo to my motor might the go. But it seems the best course of action is just drive the car as is and be happy with 210kW

id like to see a before and after dyno even if its on a normal RB20det as it would give me a good idea

As the owner of a 240rwkw RB20 (op6 highflow) Id almost guarantee your car as it is would be quicker on the street than mine.

Not sure if its been said, but for what your after, id think a 21U highflow from hypergear would be the best solution, bolts on, reasonably cheap. Retune and your away. Proven results

Tao could possibly even swap your rear housing for a 21u when he does the highflow.

Id almost think a 21u highflow wouldn't have much response difference to the stock op6 turbo you have now, but should do 230rwkw.

Unsure on the kando response, never used one, but just adding my 2c regarding hypergear turbo's.

Put money where you think you won't be regretting it later. Everyone here seems to say where you are is where you want to be for the RB20+det

Some say going larger turbo.. not much faster.

I doubt very much you'd regret having a RB25DET neo in there. Even if it made 210RWKW. If you're going to move in a direction, move in one where you won't regret down the track, seems like a clear path to me.

Or if you do go hiflow, get one that's still usable on a NEO

[Dose Pipe Sutututu]

and the NEO has VCT, which makes a world of a difference trying to spool any turbo.

The earlier you can get torque, the more exhaust flow you'll have meaning your turbo will start to boogie quicker.
