I'll be getting my car within the next few weeks. its got an rb24det with hks ecu, kkk k27 turbo, trust gate and manifold, rb26 style plenum, injectors, etc etc.

i have been thinking the k27 turbo will be too big, anyone had experiance with one of these on an rb20/25?

anyways i was thinking i'd down grade it and chuck on something abit more responsive. what sort of turbo choice would i be looking at if i still wanted to make approx. 240-250rwkw? can a 2530 make this sort of power? what about a 2835? t517z? etc.

i think the biggest concern will be finding somebody who can tune the HKS ecu (fcon?). You probably are best going for another ECU that can be tuned readily by a local workshop.

kkk turbos meant to be alright... quite popular in japan.. give it a try first!

2835 would be sweet, if you want to ditch the manifold you could go an internally gated GT-RS turbo. you will make easy 240rwkw with that. im looking into getting one of these for my internally stock RB20, and it makes over 220rwkw with the 2530. im hoping the GTRS will bring it up closer to 250rwkw.

the GTRS is still in HKS 25 series of turbos, is rated at 400ps like the 2835, but is said to respond more like a 2530. from all the articles i have been reading it is a very impressive package. only problem is they only just released it in T3 form (a bolt on for RB20/25 manifold) so it looks like the only way to get one is brand new... not many second hand bargains about.

gtrs would be the go if your after quick responce.. but being 2.4 that wouldnt be a worry at all! you mite regret choosing a smaller turbo later once you get use to the power.. keep boost down to start with and wind her up when ya ready..

as denzo would say dont be weak

yea mabye ur right, but i really hate laggy turbos :headspin:

but i'm definately going to change ecu, unless the HKS one runs awsome once i've put it all back on (i'll have to remove it all for a week or two for the rego inspection, so hopefully it doesnt loose its maps?)

what about getting another manifold and a second hand t28 gt-rs? probably budget 2.5k for a turbo swap as i'll sell the k27, manifold and gate.

so a new hks turbo is totally out of the question!

forum member Grepin has a 2835ProsS internal gate turbo on his RB25. It makes around 265rkwk at 1.2 bar of boost

I have been in his car, and it is very responsive and not much laggier than a stock turbo

      rb20de neo +t conversion - boost pressure sensor needed?

      By Neostead2000 · Posted

      Agreed with the rest. Also at least based on my own research, there are no readily available stock or close-to-stock RB20Neo maps that you could download and use as a base were you to buy a complete standalone ECU, and the regular 20DET maps don't really work well so you'd need to take it to a tuner if you have no experience. I installed an AEM V2 on my 20Neo+T and had lots of headaches until I got it to run and idle properly but I've yet to remap it fully. You have to start building up your timing and fuel maps entirely from the ground up; even the ones for a 25 didn't work at all.

      GOT SUM's RB34

      Got some decent progress after work yesterday and also today. Got the ECU all wired and passenger side interior all back together. Kept the wiring up nice and high to avoid people standing on it. Got the surge tank relays rewired and tidied up the pump wiring and cut a hole to bring the cables through.  I found a spare USB cable I had lying around so I decided to cut it up and see if I could use it for my CAN 1 bus. Turned out one of the pins I needed was to the shield of the cable so i cut it up and desoldered it and resoldered to the correct pins.  Had the issue with the powersteering hose hitting the A/C compressor and fan shroud. I pulled the bracket off and modified it to remove the front mounting point which now clears it all. Will keep an eye on it to see if theres any signs of fouling once it's up and running.

      So today I went well outside my comfort zone (again) to replace my valve cover gasket.  I have had a big leak over the exhaust leading to a lot of smoke and smell every time I drove it. The leak was in the rear driver's corner.  The job wasn't hard as such, just a bit finicky and time consuming.  The old gasket was rock hard and broken right where the leak was.  The leaky corner had so much sitting oil in it.  The good news to my amateur eyes was no buildup or sludge under the cover. It all looked fairly nice in there.   I haven't started it yet. I ran out of light and body when putting the coils and injector loom back in. Probs only 30min left for the morning.  I was so nervous putting the cover back on, I must have lifted it 5 times to make sure the gasket was still seated properly. God it's going to be nice to be leak free and not make other traffic light queuers think my car is about to explode.
