Hi all,

I am looking at hearing peoples experience with these two turbos. I have heard a lot of good reports about both and still a lot of people are using both. The only person I know who has used both turbos on the same car is simon A31 but he didnt reply to PMs. So your experience would be appreciated.

Hi all,

I am looking at hearing peoples experience with these two turbos. I have heard a lot of good reports about both and still a lot of people are using both. The only person I know who has used both turbos on the same car is simon A31 but he didnt reply to PMs. So your experience would be appreciated.

Slide hi-flows fairly much just bolt on with you're stock equipment. kkr requires a v-band flange for the dump pipe and a screamer or plumb back pipe for the wastegate.

I do all my own work and they are the same price "fitted" so dont worry about the extra stuff that the KKR turbo will need.

I am wondering about longevity of the two turbos and spool up time and overall power output. Just a comparison really of the two turbos.

the kkr's usually come with everything you need to make a dump so fitting isnt really a problem (some come with oil lines). as for reliability - ive got no idea. im pretty sure theyre a journal bearing turbo (for around $900 they're not going to be ball bearing).

unless i had some solid results id be going for a slide hiflow.

Ive Pondered Both Options, ableit KKR480.

But decided to go Garrett GT3076. As Ive changed direction with the car.

If you want to wait I would go the Slide Hi-Flow, As Aaron isnt doing them for a while,

If you want a Turbo now go the KKR, HPI had some good results with a KKR 480 on their RB24 and the LS1 Edit Gen-TT systems use the 330s/380s and I havent Heard of anyone having problems with them.

The Wastegate flap is inside the Exh Housing so a split dump/screamer is out of the question + You can buy the V-band Dump Pipe To suit RBs now from Otomoto.

Hope This Helps

wouldnt be disappoointed either way, hiflow is probably safer option, i had one from gcg, geat turbo. and no problems selling it when i went larger either. theres always someone wanting a hiflow but as for a kkr430....well who knows.

Yep. SLIDE isn't doing high-flows anymore, so your left with no option there, unless you decide to go with a GCG high-flow which is a fair bit dearer than the prices which SLIDE was offering.

I prefer high-flows my self as they are guaranteed 100% bolt on, only slight modifications to oil feed line for greater oil flow but nothing more than that really.

Plus they look stock, and you can never get in trouble for having an after market turbo.

But it really comes down to want you want to use the car for. Do you just want heaps of power, or do you want to use it for drift/track/street/drag? Or maybe you want it to be really responsive with no lag? And it goes on.. How much power are you chasing?

Anyways, I am just a bit confused with this thread. Subject says KKR430, but in the replies people mention KKR430 and KKR480.. lol

Just wondering if someone can clarify which turbo is a good comparison in size to a SLIDE RB25 high flow for RB20.

Thanks :thumbsup:

no im not the wanker who didnt do the oil feed modification,infact the builder of the highflow turbos done my oil modification and sent it up with the highflow...so before u go and point fingers i aint that fkn stupid.like i said i wouldnt bother with a highflow.

lol thanks for the reply guys.

I already have a highflow on order and it is just taking way too long, that is why i am considering something else. So thanks for your help.

Seeing as there is some bad rep for the highflow turbo, Any bad rep for the KKR turbos?

So this is only on the KKR480? When you are saying wastegate flow problems I am assuming it is not flowing enough and over boosting?

My experience was with a KKR280, firstly had to replace a faulty exhousing, then had to mod it extensively to stop it overboosting, not much fun-pulled the turbo off 3 times on the dyno.

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
