I've got a Nissan 200sx RS13 (UK spec, had the CA18DET engine in her) (just thought i would point that out so you know what car the engine is now in)

I’m planning to run something like 300-350rwhp, but I’m a little unsure of what I really need/want, I need friendly spool up and a healthy top end for long drifts, I think the RS13 is a little lighter then the Skyline but unsure once again (I’m sure you will tell me for sure :P )

I’ve been looking at the HKS GT-RS, I’ve been told it’s a good turbo and will do the job, but not having much people around here with RB20DETs its hard to tell how good this will be, I know you can’t really say for sure with out me pointing out the rest of my spec but if you can give me an indication of what would be best as its not all about out right power with this sport (as you know) drivability is the order of the day :D

I think i've read the bottom end is good for 450bhp, is that right.

If you can, tell me the spec i would need to run good power small lag?? I'm saving for a high spec rebuild :D

HKS GT-RS, HKS GT3037s, HKS GT2835 pro s, along those lines :D

Any help would be appreciated :D

if you want something cheap and nasty for drift a T04E with manifold should cost less than a grand. Its got a nice low RPM spool

On a best case scenario with an RB20DET running it at 15psi, you should get the following:

2000rpm - 5psi

3000rpm - 10psi

4000-7000rpm - 15psi

should be good for around 300hp.

An HKS 3037 is similar in specs I think. A lot of guys use the 2530 as a standard bolton upgrade for the RB25DET's.

Cool, this would be better then the HKS GT-RS :P

Parts i've got so far, Tomie Pistons and rods, HKS steel head gasket, head ported and polished Tomie 260degree cams, custom plenum, nismo 550 injectors, z32, trust massive intercooler, blitz nur spec, HKS filter, Power FC (sorting at the moment)...........you get the idea.

What are the spes of this T04E ??

cheers

my r32 is an ex drift car from japan and its has an rb20det with a td06....

this has huge top end power currently its only putting out about 185 rwkw on 10psi but the diff is screwed.... so should be about 240ish on 16psi hopefully

Interested to hear how you go at 16psi,

I was making mid 180rwkws at 8psi, with 17psi it made 222rwkws. I would have thought it could make a bit more power with the additional 9psi... but meh, its a dyno figure, it feels pretty damn spritely at that power / boost level:)

PMSL, most of my build spec has already changed :( (RB24DET on its way :()

Anyways just got my HKS exhasut manifold with T3 flange, was thinking of getting a GT3071R maybe in .64a/r with 4 inch outlet and 4 inch inlet, external wastgated (what size wastgate shoud i use)

whats your thoughts on that ??

the GT3071R with an A/R .63 would be ideal if u were building your engine as a RB24, otherwise a little more responsive would be the GT3071R with 90trim exhaust wheel. this is identical to the HKS GT2835R.

44mm external w/gate (Tial to be exact) should do u perfectly.

it sounds like it's gonna be a nice toy to have, enjoy

@Morgs

Yeah building it myself at the moment, put the order thought for the 82mm Tomei pistons just got to await for them to arrive :rofl:

The crank has gone off for cheacking and polish and should be back ready to start machining the block :D

I'm looking into how to go about having the head machined out too to take the 82mm pistons, so i guess i will be able to stick with near normal steel headgasket and it will lower the CR a bit :)

@RS500

Yeah seems to me to be a good turbo and nice map, i don't know if i want the .64a/r don't know if it may surge or not ??

@180bfj20det

Yeah the GT30R is a great turbo but i feel its a little big for what i want, i must say power is not everything for what i need.

Dude you have too much money :rofl:. But damn thats gona be one hella awesome engine/S13. People wont know whats hit them!

Im not sure what turbo, but if all is set up well even something of decent size should come on ok, just might have to drive the car a little different to cope :D

With the 2.4L and compression, and i recall you are goign to be runnign cams etc, then id be looking at a HKS2835. If your a Garrett guru like some folk here and know the general equiv then id be running one of the m with an external gate and nice tubular manifold wrapped up and bracketed off the block.

With this style of 420-450hp turbo you will have some serious stomp and make around 260-280-rwkws with good midrange.

If you want a bit more then i would be tempted to run a 500hp GT30, but having now been in a few GT30 RB25s id say the GT28 series turbo is the go for an all round performer. Basically because i have the Trust equiv on a std RB20 and im stoked with the performance, but a new BB Garret would on paper be a bit nicer

Yeah sounds good dude, only problem i've already got the manifold :Oops: i hope its to your liking as its to mine :D

Just fitted it as it only arrived from japan yesterday morning :D :wassup:

;)

I'm going to have to look into the HKS GT2835 as it pops up alot, is it the same spec then (or near) as the GT3071R from garret?

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
