i could probably find all of this onfo if i looked real hard, but eh, i figured some of yall knew first hand. was wondering some of the basic specs on these 2 hks turbos. and what kind of power numbers youd see out of these 2 if you had them on the same car. well built to handle turbos of this size (1600 secondaries, 3 row fmic, all the ussualy works) running say 20-25psi... i was leaning towards the t51r but didnt know much about the t04 so i didnt wanna count it out yet. thanks

didnt specify what i really meant... im curiouse as to where each makes peak power, where it hits full boost, ect... not really physical specs like a/r and whatnot

Im still having a bit of trouble finding what i need. and i know some of you guys who have been around rotaries a while can help me out. I plan on making my car more of an interstate slayer rather than a strip car. so response isnt a big deal. so im still thinking maybe the T51R SPL, cause im wanting to hit in the 500-600 range, running somewhere in the 20-25psi ballpark, price and reliability is not an issue... this will be strictly a once a month fun car... so if anybody has any info to help me out, lemme know. thanks

yea i watched a vid of yours running that nice 10 second run . how does the kai run up high? hows the dropoff? and what kind of hp# you seeing?

LUPE

HKS T51R SPL/KAI are outdated turbos. You can find better turbos for much cheaper these days.

Plan on blowing up atleast 10-35 motor before you reach your goal.

LUPE

It pulls hard up top. You've got to shift quick or you'll bog between shifts. HP is around 533rwhp.

Going to turn it up to 30+ psi in a few months.

that unachievable huh? lol well what would be a more modest goal? cause im not looking for that much trouble haha. and what turbo would you suggest then if not a t51 kai/spl?

no ****, with a kai, whats the upkeep like on your car making that kind of hp? that sounds about like what i want to be close to... though my et will be a lot lower cause ill be running some big ole 3.9 gears

LUPE

It's achieveable. To make things easier, just send your car to someone and have them completely build it. Pick it up tuned and ready to go.

Upkeep, well I'm on my 11th motor if that tells you anything....

For you, I would go with Davinci Motorworks turbo, AF61R.

RETed

Don't mind these idiots...
The HKS T51R Kai and SPL are just rebadged Garrett GT42/45 turbos.
If they are calling the Garrett GT42/45 "outdated", oh boy...

LUPE

Like you know ANYTHING about making power. What do you have? Exactly.

TurboII RudeBoy

REted is this guy serious?

Brian7

Avoid both turbos. Your best bet is to purchase a 'kit' from one of the vendors here.

MARTIN

I dont know who's building or tunning your motors but 10-35 motors, thats fukin rediculous. I about there and this is the first motor with used parts....

LUPE

I was being sarcastic.... try getting good tuning info in the 90's. There was little to none.

LUPE

what do you think, groupie?

Ok. After reading all of this. If i go T51R SLP or KAI. 1600cc secondaries, good FMIC, Power FC, all of the other ussual mods to make big power, and run say... 22psi and have steve kan tune it... get it to the 475-525whp range... what would you think id get milage wise out of it before a rebuild? if i dont run the **** out of it and just use it as a once a month fun car? cause i REALLY cant handle rebuilding too often, but once every 50-75k miles i can handle... what you say?

LUPE

50-75K on a 500whp rotary? Dude, I know you're new to the rotary deal but......... no fricken way.

First, you're going to need to run race gas for that. Second, if you're only driving it once a month like you said............ it should last you a couple of years

TurboII RudeBoy

First of all you can make 500 rwhp with pump gas several people have done it , depeneds on ur tuner , o I see you've been told you can 't it's ok.I made 431 to the wheel's with a 13b-re ,t66 and drove it everyday for 2 years str8 no problem , pump gas. O and no need for stupid remarks calling me a groupie, just don't state dumb facts.

well thats good, well... estimate for me how many miles you think id get? and yea, i was planning on running a mix fuel anyway, maybe not straight race, but ill have to see how it turns out i guess, dunno till i have it all done. tuner will be kan, so maybe he can do something to let me keep it 93 octane, even if i gotta turn down the boost a bit and drop out of the 500whp range... or i could have 1 set for high boost w/ race fuel, and one for low boost w/ 93 oct. I DUNNO... but yea, bryan of bnr ran 435whp for a long *** time in his fd on 93 octane (almost possitive it was not race fuel) just fine, so im pretty sure kan can pull something out of his magical *** and get me to 500ish on regular pump gas

RETed

I wouldn't know.
I have him on ignore.

Those HKS GT-series turbos use Garrett GT-series off-the-shelp compressor sections, including the HKS T51R Kai and SPL.
The HKS turbos use some funky turbine wheel and A/R that are not part of the regular Garrett catalog.
Garrett produces those turbos for HKS according to their spec; those turbine sections are proprietary HKS only, and Garrett will not sell them to you as parts.

What are you trying to do?

Is this a street car?
An HKS T51R Kai is borderline streetable.
I would not recommend the T51R SPL - we're talking powerband after 5,000RPM.
BP?

Swapping in 1600's will not support that kinda power.
Stock 550's primaries and 1600's secondaries will barely support 420hp at the wheels at stock fuel rail pressure levels.
If you're looking to make over 500 at the wheels, you need something a lot larger than your stock 550 primaries.

How much money are you willing to spend here?
Unless the motor was rebuilt recently, this is not recommended on a stock block.
You're looking to DOUBLE the stock horsepower out of the motor.

I don't like a Power FC in this kinda application.
A full stand-alone is a lot more flexible.

It really sounds like you're grabbing a bunch of parts from catalogs and dreaming to put them together.
This is really a $10,000+ project, unless you got hook-up's for parts?

Mileage?
You're worried about how long the engine will stay together?
Man, this is not something most people worry about if you're shooting for 500+ hp.

Once a month fun car?
On the street???
