Kinugawa Turbo Internal Gate Quality

[CRSKmD]

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

[scotty nm35]

Unless they enlarged the wastegate puck and opened up the hole I would stay well away, stick to the products you know won't boost spike, such as Hypergear or Garrett, or going external gate is the best option imo if you can keep it looking stockish. There are some great gains to be had if an external setup is done right.

yeah currently making just over 210kw but was looking at stepping up to a bigger turbo/more power but with similar response.

i had heard the hypergear high flows where laggier than the TD05 18g kandos?

[scotty nm35]

Hypergear do a wide range of turbos with varying flow, some like the SS2 are very responsive for their power capabilities, and run a more modern CNC compressor, much more efficient than an old TD cast compressor. This will add to the cost of course, but I am sure he could make a cast version for similar pricing to the Kando with the same wheels.

Garrett do some nice GTX28 series turbos that would be perfect on an RB20, but you are looking at twice the cost of the kando.

I would contact Tao and speak to him regarding your goals, you have nothing to lose, and it's not something you want to jump into without researching all your options.

[CRSKmD]

definitely worth finding all the options and pricing before i spent the money!

i am getting a leak down test done in the next week to check on the engine health before i even think about buying something

[scotty nm35]

Good idea, if it's no good a stock RB25det Neo would get the power you are chasing with no lag at all.

yeah det neo would be the path id take if my RB20DE+T dies. but i love the 20's hahah

Another option is to run e85 on the turbo you have now, more power potential just by filling at a different pump, as long as you have the injector overhead. Obviously best if you have a servo nearby that sell it.

I have ported the shit out of my kinugawa td05-18g wastegate hole, it helps but still does creep up to 17+ psi around 5500rpm, on an unopened rb25 with usual basic mods. Although, it seems the turbo works best over 1 bar anyway. Electronic boost controller is used just to bring it on boost, and with the 8cm housing it is defintely not laggy. Have one of the new hypergear hiflows on the way just cos, am keen to see the comparison between the 2.

Currents mods not really ideal for E85. injectors not big enough for E85 and turbo is the bottle neck as it is.

RB20DE+T

RB25 turbo (0p6/neo)

R32 GTR injectors

Ebay plenum

R32 GTR cams with solid lifters

profec b spec 2

etc

would be interesting see a comparison of the results of the two! be sure to let me know?

[hardsteppa]

guessing you're not in Brisbane from your car pic there but if you are you're welcome to have a drive yourself to check it out before I swap 'em over.(td05 will be for sale cheap too , if you were considering one of them)

[CRSKmD]

Yeah from SA so not really ideal. a before and after dyno graph to see the response/power difference is probably the best i can do

What turbine housing are you running? Any pics? There are a few different versions now...and the latest offering which is a Skyline specific T3 "looks" right compared to the avomination housings they use to offer as their internal gate, T3 offering.

If someone wants a new 18G cheap I have one laying around which is no good to me since my 20 overheated

[STATUS]

Garbage, had more than 20 odd be untenable due to massive creep.

[Roy]

I get that these ones are RUBBISH

These ones Look as though they at least stand half a chance of not being junk

[hardsteppa]

Roy that 2nd one is the one i use, i have both the 10cm2 and 8cm housings. It is not a physically small turbo, turbine housing is much larger that stock, so i consider its response to be very good, it may not have any boost creep on a lower displacement rb20 with the wastegate ported out?

[Roy]

Got a graph? I would have thought an 18G would have almost std response and capable of 240-250rwkws and the problem being boost falling off both spiking

[hardsteppa]

it may well hit 240 with a decent ecu, I am using stock ecu with safc neo though and do my own tuning so no dyno sheets...

[Roy]

So you say etc is used... What type?

[hardsteppa]

Ummmm. Type of...?
