Whats The Cheapest Way To Hit 260-270rwkw?

[Beeble]

I got that Nengun deal a while back.

Very happy with it.

It's currently $4250 delivered, plus tax/duty of course

I think the 260-270rwkw with stock motor and GT-RS is more the exception than the rule though, and you'd need cams to get that power figure. I'd say 240-250 is more likely from what i've read and seen. They CAN put out up to 300rwkw - but if you are expecting to get 260 out of one you should prepare to possibly be a little disappointed.

For 270ish i'd go the 2835ProS; it seems to be reliably making this sort of power. If you want HKS badge, that is.

And to be fair with the GCG Hiflows - a lot of people only get 230-240rwkw with those aswell. Sure some are getting 260, but i wouldn't say it's a guaranteed figure. Maybe they have cams aswell?

IMO the GCG Hiflow and the GTRS are pretty similar in response and peak power. i did a LOT of reading and enquiring around this topic not so long ago. The GTRS possibly has more in it at higher boost (18-19psi) but i only run mine at 15psi, which seems to be what most of the hiflow guys run at, for what it's worth.

The 2835ProS is a slight step up again; bit more lag, bit more top end.

Hope that helps a little.

Yes it does, thank you beeble.

Im thinking the 2835 pro s or the gt30r are the best option for my power goal.

Does anyone on this forum have either of the two combinations with the .86 exhaust housing. Does the 2835 suffer from boost creep with an internal wastegate, or can you set whatever boost you want and not worry about it?

Im just leaning towards it now because I won't need the external wastegate, and i can hopefully low mount the HKS turbos.

Thanks everyone for the helpful replies.

^do a search for " 2835* " and you will get at least two threads with pages of info on that turbo ; the installs with pics and any problems and issues along the way. From approx oct/nov/dec last year

how about the gt3037/3040 turbos? how much power are they good for, and do they respond as well as these turbs mentioned or is there alot of lag to go with them???, im too looking to go down this track this year some time, but im looking for more streetable car then a top end lag beast.....

What power figure did you make?

^thanks

Made 230-240rwkw at 15psi with the GT-RS.

The tuner said he could have squeezed 250 out of it if i wanted the numbers on the dyno sheet... but i'm really just interested in a quick street car with lots of punch out of corners.

Turbo honestly is very close to stock lag-wise. Most impressed for what i wanted it for.

More than likley they havnt upgraded their injectors, so 220-240rwkw is the limit with a rising rate regulator.

I have the GCG and am very happy with it. At the time there were NO other turbos that came close for the price (and I didnt want to trust the second hand ones - who honestly sells these with only 2000km since upgrade? is that made up of 4000 quarter mile passes?? )

Dont forget to factor in the cost of mounting these other turbos. GCG is truly a straight bolt up, many others require fabrication of oil/water lines and modifications to dump pipes/exhaust etc. The GCG can be done easily by the home mechanic in the driveway, some of the others are not so easy.

hey im real interested in the 2835 and was wondering how much power you can push out of them, im thinking of the nengun kit delivered to door, as im aiming for 250-300 rwkw, guys who have this amount of power, how do you put it to the ground hehehe, or dont you!

Im hoping for a turbo upgrade with response close to stock as i would like to use my 25t as a track car and daily driving street

thanks

I dunno if people are just plain lazy or not... but who knows.

I have done all the work for you (read taking 30seconds of search)

A HKS GT2835 Pro S is more suited to 270rwkw than a GT-RS is. The GT-RS would be right on its flow limits at that power level, where as the GT2835 would be able to do it no sweat. This is because the GT2835 Pro S has a bigger trim compressor (56T vs 52T) and a larger turbine (56mm vs 53mm) than the GT-RS and thus is more suitable for a RB25. The GT-RS is more suitable for a SR20.

-IMO-

how much power can i put out with stock bottem end? just wondering if it will support 300rwkw on a very good tune?

[copycutter]

thank you r31 nismoid for all the links - they were very helpful, I can see how you have to constantly hover over repetitive threads like this to offer this kind of advice.

I cannot for the life of me work that search function but im a stoopid head :lol: whenever I type in a phrase to search for i get the red error message..

I appreciate now what these high-flows are capable after reading bullant47's thread in particular... It seems that vg30 exhaust housing made the world of difference - definititely something to consider if the GCG option is viable for me at the time.

im running 294rwkw on 18 psi on std bottom end.. seems perfectly fine and AFR's are good.. getting new WG and coils and trying to hit to 300rwkw mark with out any more boost.

BU5TER's old engine i think was running over 330rwkw and had std bottom end for years!

so it can take it..

Just wanting to figure out what turbo option would be the best in terms of price, response, and overall power band.

I was originally thinking a gt30r with high-mount manifold and tIAL gate' on about 17psi should hit the mark - not too sure tho.

I was having a look on the sticky thread about the rb25 turbo upgrade, and im wanting to find out more about the hks 2835 pro s... i tried searching the forum and the net and couldnt find any rock solid specs or real-world figures.

I'm just leaning towards the internally gated turbo now because its cheaper to bung one on. But would one of these fit low-mounted in a 180sx? And also, what other mods besides the obvious ones are needed for this power. I dont really want to have to do cams unless i really need to..

Cheers, Guys B)

Hey Tuna,

I will let you know how mine goes. Power FC, injectors, cams, GT3540(better match apparently than 3040 with no worse lag), fuel pump, 48mm pro-gate, split dump with removable pipe to screamer. All getting done currently and should be ready early april.

Cheers

ah thats pretty good, im looking at running 300+ rwkw with a std bottem end or if it blows on the way. Im just testing what the rb25 can take really.

[R31Nismoid]

no problem tuna

im a search expert lol.

As for the RB25 bottom end, up @ the 300rwkw, just hope you dont ping.

All it takes is a bad batch of fuel and things can get costly.

How long have you been makign that pwer for? Did Bu5ters engine run for years? It ran a hell of a long time considering the use it got what seemed most Wednesday nights

Guys, it made that power but it sure-as-shit didn't make it for long...especially the way Brett used to rape it.

I think the best results in terms of longevity have come from guys running a sensible tune to about 300rwkw.

HOWEVER, everyone knows that the CHEAPEST way to 260kW is to cheat

It wasnt years, but it didnt die a bad death, in fact i wonder how long it would have lasted if the tuning was left alone? And the revs and runs that engine did with that power...

..anyway
