Hello guys currently im running a 10.5hotside evo 8 turbo with kinugawa 20g billet compressor wheel im on 323whp on 24 psi 98Ron fuel
with all single bolton (with bigger throttle body)except cams and injectors which i will be willing to add soon
will going fp 71hta give me any gains over my current turbo?
My target is 400whp on pump gas no e85 here and heard horror stories about wmi setups

 

On a low reader dyno the 71hta will do 360-370whp on pump 98 ron with a set of cams and 700cc injectors. There is no need for a larger t/b. I recommend using hks 272 cams. There is also no actual need to go to the 71hta as it has a 51,2mm inducer and your 20g is at 52,4mm inducer, both on very similar aero. The 71hta will produce a bit more hp due to its larger exhaust wheel, something in the range of 20whp or so. So in other words you'll be making 350ish whp on a low reader with a set of cams on the 20g, and 370ish whp on the 71hta on 98 ron.


Not worth the hassle in my opinion.

Dont do hks cams terrible advice

My hta71 made 340 whp when i was on stock injectors at 16 psi limited by 91 oct and stock injectors


When i installed 1000cc I made 400 whp on pump

 

Hks 272 are perfectly fine for the turbos mentioned here. You being ignorant does not make my advise terrible. There is no way an engine setup with either of these turbos will do above 370whp on a properly calibrated low reader dyno on 93 oct i.e, and it will take 1,7-1,8bar to do so, he also needs the 700cc injectors, the stock 560 won't cut it, there is also no need for 1000cc on this setup. Other than that I can make a dyno show whatever figures I want from a setup.




* HKS cams have an effective duration of 212 and effective lift of 10.8 at the seat with 10.6 at the lobe on stock springs. Their LCA, ramp, flank, nose characteristics are more than adequate for the CFM these specific little turbos push. These lose nothing on the low end in comparison to the stock cams and are more than adequate at the top end for this setup.




Use hks 280s or s2 cams on a setup with an fp red size turbo and onwards.

so what do you recommend as a turbo to hit 400whp on virtual dyno i just want that 80 whp difference between my current setup and the target one?

 

how much boost you were running for 400whp and did you do it on stock cams?

 

S2 around 26-27 PSI

I just wouldnt use HKS cams there are better cams out there. I would even consider S1 over HKS 272. If a local has Kelford 272 even those a great cams on stock turbo.

Come on its not 2006.

Get ID1000 the car will drive so nice and almost like stock. Dont cheap out on injectors and HKS cams if you buy them new arent cheap. If you get a steal I have had two sets and had to sell them off for like 200 bucks because no one wants to use these anymore. If cash is tight for the money used hks I guessare decent cams but even so there are BC 274/276 which are similar to S2 with 11mm/11.2mm lift for around 350.00 bucks brand new.

400 whp if you have quality octane on E85 or Q16 450-480 WHP is realistic.

HTA71
S2 cams
ETS or Muse LICP
Crushed OEM E9 BOV
ID1000
Walbro 255
Down Pipe

Maybe o2 dump and 3" or 3.5" fmic core.....Buschur or ETS.....but a muse core should do the job fairly cheap

 

The HTA71 is the perfect turbo for a 2.0L Evo, IMO

I made 450ish with S1 cams, Blitz FMIC (just under 3"..You don't bed a big one), 3" TBE, open air filter, 255 pump, and injectors. E85.
It doesn't take much. Super responsive and plenty quick.

 

not sure about quality of our fuel LOL.i already have a buschur intercooler along with lower and upper pipes the only pieces im missing are cams and injectors e85 isnt available so it doesnt matter to me how much i can take out of the turbo on it

 

Results on e85 means nothing to me as its not available in my country(wish we had it).the bigger comp wheel size i have is what made me concerned of swapping to 71hta and not seeing gains even though my car is slower then an 8 on stock IX turbo thats what is making me confused

 

Can you get vp racing fuels or torco?

Torco is good for 2 degrees of timing and an extra 2 or 3 psi


You pretty much have the most essential parts mparts maybe throw an o2 dump in there.

 

I have lived abroad and same issue. Usually people do q16, c16 or high quality octane booster such as octanium/torco/boostane.

 

are these boosters some sort of cans i add to my 98 ron fuel if they are ill try to search for them i have always heard of people on race fuel here while drag racing but never actually asked where are they getting them but im 100% they didnt get them from any gas station as these station sell some sort of trash products and call them octane boosters while they do absolutely nothing

 

Virtual Dyno in what mode and what smoothing. You can make 400whp in Dynojet mode and 0 smoothing or smoothing 1 by putting a set of hks cams in, a bit more aggressive map and boost, on good quality 98 ron.

But if you want true 400whp then you either need to at least use Dynojet mode in smoothing 6 VD in Virtual Dyno mode on smoothing 3 or 4, or even better Mustang mode in smoothing 3 or 4.



The best thing for you to do is use your current 20g billet compressor turbo, but upgrade the turbine wheel to the tdo6hr one, which will basically make your turbo an fp green htz.



Use hks 272 cams with the above turbo and do not listen to ignorant people and bull**** arguements. The hks 272 cams will give you the best powerband with these little turbos and are more than enough to take advantage of the cfm this turbo will be pushing.


With the upgraded tdo6hr wheel and the hks 272 you will see 400whp in VD in Virtual dyno mode.


The s2s are for at least fp red and onwards, fp black, 5858, 6266, gtx3582r, 6466 gtx3584r.


The s3s for 6766, gtx4088/94r, 6870, gtx42r etc.




And since 2006 was mentioned, I made 362 whp on 100 oct ron, on a low reader cartec dyno, comparable to a low reading Mustang on stock turbo and hks 272 cams.

The characteristics of the cams are more than enough for the suggested turbo. In comparison the stock usdm/eudm evo cams have an effective duration of 186 degrees and 9,8mm of lift.




On the setup I'm currently running on my car, self built/mapped, I've made 810whp in VD on Dynojet mode and smoothing 6, and 716whp in Mustang mode and smoothing 6 on 98+ ron very good quality pump fuel. The 98+ formula it is more effective calorific wise and anti-knock wise to the previous 100 ron formula the same company used to offer. So pump fuel can take you a long way if it is of good quality.



You can put whatever you want in your car, I gave you my recommendation and I have nothing more to add on the matter.

a bit defensive there is a reason why no one uses hks anymore....I have ran 300 whp set up to 930 whp.....

I have tried

S2
HKS 272
S3
STM650
HKS Step 2 274 278
Tomei 270
R2
Kelford 272
Kelford 280
Kelford 276 HL
Kelford 284 HL
S1
HKS 280
M2
BC 274/276

Pretty much have ran all of these on stock turbo up to a green besides STM650, Kel 280, 284 HL and S3 these are for big power set up.... HKS have been the poorest performing ones....

On HKS 272 to S2 I picked up 20 more whp on a stock 2003 Evo 8 turbo. HKS 272 cams unless money is tight or you are getting them for free should not be an option. Ill wait for other posters to chime in and enlighten.
