Guys,

My Evo modifications is Stage one which are:

1- filter Intake
2- Downpipe
3- CatBack Exhaust
4- Bigger Injectors 720 + fuel Rail + Fuel Pump
5- HKS Cams Shafts 272 & Cam Gears
6- Tuned Apexi Power FC ECU

Anyhow, Im here to get an advice for turbo upgrade! Friend of mine recommended HKS GT3240 and I purchased it already but the issue now I’ve read and heard about its so dam laggy!!!! Is that true!!! Hope not…

Pls advice and shall be appreciated

BTW, Still have the chance to replace it with other HKS turbos!!!

Thanks

 

Why would you buy something without even knowing what it will do?

That's just one of the stupidest things one can do actually.

HKS GT3240 is about size of a Garrett GT3582r, so yes it will be laggy.

Would it be too laggy?

It depends on your supporting mods and how you define laggy.

To some people even GT37r, 40r isn't too laggy.

If you don't want lag, and only have choice between other HKS turbos, go exchange it with 3037s....that turbo won't make as much power as 3240 though. 3037s is rated at 470ps and 3240 is rated at 580ps.

 

Thanks for you advice evilbada, Oh my god your advice is so dam valuable non of Evo experts has said that, Oh God finally I found an Expert!

I bought this Turbo cuz an Evo master has recommended it and experienced it but he never mentioned a thing about lag!

If its about exchange then I would not seek an advice… Im here for Solutions for get away from lag if possible since this turbo has advantages than 3037!!!!!


Oh God, U such a smart Thank u again for such valuable info...

 

HKS's GT3240 is a real orphan , its closest cousin would be a GT3582R but with some significant differences .

Firstly its turbine , there's nothing GT32 about it . All it is is a GT35UHP turbine thats been cropped or clipped if you like down to GT32 dimensions ie approx 64mm and in 84 trim .
Secondly its compressor wheel is the same series as the GT3582R's (68mm BCCW 18C or GT40) but in 54 trim rather than the 3582R's 56 trim .

Could I possibly have the ID tag numbers off your GT3240 because its one of only two HKS turbos I don't have unit and cartridge numbers for .

Thanks , A .

Late Edit : I believe it was only ever sold with a bored out HKS T28 flanged GT30 turbine housing in 0.87 A.R

 

it will be laggy. as long as you have the supporting mods and a proper tune you can get pretty good performance out of it. hks' u.s. support is crap though. i called them one time about a problem and it took forever to get a repsonse so i ended up selling the item and bought another. you should definately do more research on something in the future before buying it. if it wouldve been me i wouldve gone with the new buschur hta35r. faster spool times and killer performance. i give them an a plus. im actually considering getting rid of my custom t3/t4 setup to get one. good luck with your build

 

The 3240 will spool faser than 35r. Turbine wheel is 32 size. Exactly half-way between 35r turbine and 30r turbine. Only HKS sells this size turbine. Compressor wheel is 1mm smaller than 35r as well. 707503-10 is one I have here.

nice thing about 3240 is all the sizes of exhaust a/r available for it. double what garrett typically offers.

 

Thank U all... so guys what do u think? which one should i go for!

I know u gonna ask me about what numbers i need. Ill say i wanna go above 500hp with possible tourqe i can get with that HP.

so consider my situation is urs, u r between two choices:

1- HKS GT3240
2- HKS GT3037

no complications pls!!!

Thanks again...

 

largest 3037s has 57mm inducer and 76.2mm exducer (56trim) which is same as 3076r.

The only thing different is various exhaust housing offered by HKS.

So with this turbo, you will have hard time making above 500whp.

Stick with 3240 if you must,

that will allow you to make 500whp.

3240 is nothing more than a fancy 35r made by HKS that will be more responsive than the conventional 35r with the expense of top end.

The HTA35r will be closer to 3240 responsiveness and still have crazy 35r top end.

 

2 important things- check your elevation ( the higher above sea level the worse for spool)
also contact user name 3240 - he ran this same turbo and now has the kit for sale

also conact this person http://custom.autos.yahoo.com/galler...view-car-14293

its better to contact people who have had first hand experiance first

i just waisted 5 mins of my life searching for you - next time utilize the search key and welcome to Evo M

 

Thank U guys, I really appreicate all this

thatsMR2u: Thanks for ur time dude... u r a good man

evilbada: Thanks again, I think I will stick with 3240, u r

all guys thanks for the info...

See ya after all fixed and will report u with results....

cheers,

Sultan

 

hard time, no. with race gas and good mods, 500whp is doable. i made 472whp with 25psi 93 octane and 100% meth with the ATP 3037s

 

So that would make the GT3240's CHRA number 707503-10 .
This would be possibly be the earliest GT35UHP turbine used in a small frame GT BB cartridge and IMO in a smaller comp trim could have been a better thing for 500 Hp .
Anyhow many of these HKS wheel/trim optional Garrett cartridges have been around for some time and would not necessarily be optimal with what is known today turbo tech wise .

Cheers A .

 

any updates on how this setup worked for you...?

 

holy dead thread. lol

He hasn't been active since this thread lol.

 

I made 456 whp on pump gas 25psi on the hks 3037s. but gunna switch to the gt3240 and ams stroker.
