Sup guys !!

NEED YOUR HELP !!

when you guys bought YOUR STAGE 2 turbo kit..what was your wastegate size 50mm or 40mm ??my car is currently at PFS getting my turbo put on but for some reason there seems to be an boost crip issue and seems to be a problem with the wastegate. I've always believed that my wastegate is an 50mm since that's what it says on their web but I was told that time when I purchased ( two years ago..but always been in the box and i just put the car in the shop back in Febuary ) my turbo, stage 2 came with the 40mm. I misplaced my invoice and don;t really have any ground to back it up other than people who bought the same turbo kit from them...Thanks guys

 

I can tell you one thing, 40mm wg is TOO SMALL! I blew front and rear plates because of BOOST CREEP from that turbo. I had to fork out $600 more dollars to get the 50mm wg. So, just sale your 40mm wg and eat the difference.

 

That kit comes with he HKS standard wg. This wg is smaller than the HKS race wg which will fit SR's cast manifold on the Stage II kit.

I also had boost creep with that kit and we never found out why. When I was having a very experienced tuner/fabricator fab up the wg outlet to dp piping he commented that the standard wg should flow plenty for my application. Anyway, decided to change to the HKS race wg (thanks to Ray for the free exchange) and still had creep.

Looking back I was suffering from ignition problems and a failing fuel pump so I never did nail what the root cause of the creep was. Didn't find the bad pump till it took the motor out at high rpm. When it all went back together and I sorted out the fuel pump and ignition issues there was no more boost creep!

 

but why are they sending the 40mm in the first place ? according to their web site..Stage 2 COMES with the 50mm and Stage 1 comes with the 40mm.

 

anybody have a pfc map for this turbo or something similar?

 

Guys,
How much did everyone spend on that turbo kit? RESOURCE says that BI-STATE CUSTOMS sell that same turbo for $600.

 

Is there a turbo or knock off kit that Bi-whomever doesn't sell?

 

it is the holset turbo. he looked at mine when he made my manifold and thinks it is the same turbo. i think they are different inside.

 

Yes, we offer a twin T04E kit, T70 kit, t72 kit, t51 kit,t04s kit,t04e kit. We also build custom applications with many internal options as well. Why such the hostility?

 

They are the exact same basic holset hx35 turbo that costs 400 brand new(Inside and out, except SR grinded off the holset markings which is very obvious.. It's not a bad turbo..........Ernie T whoops butt with it

 

Just looking at the HX35 specs on the Holset site.

Seems like Compressor A/R is .7 and Turbine A/R is 1.2.

Can anyone confirm this for the SR ones, since they won't tell us.

 

Resource,

No ill will intended, just a poor attempt at humor.

 

One of the local guys here has one as well. It made 445 rwhp @ 17 psi on pump gas. As Resource says it is a holeset. The guy also had over boost problems, I was driving and it spiked to 23 psi . The car had the 40 mm wastegate which was the prblem. Quick spooling for the size of the turbo and with more tuning I believe another 30 rwhp would be easy. Don't know about reliability though, I've heard good and bad.
Ernie ran a 10.8 I think at 128 on a stock reman... ?

 

my greddy wastegate works well its off topic but it came with my T78 kit. holds boost down to 9psi! i was pleasantly surprised

on topic.......40mm is small. you can never get too big of a wastegate

 

When Ray first started selling the kits, he used the 40mm wastegate. He then changed after complaints to the 50mm. You many still be able to get the 50mm if the 40mm was never used. Explain the situation to him. But there is the possibility that you got the "stage1" and not the stage 2. It is a nice turbo. Reliability is questionable as I had to rebuild mine 8 months after I had it.

Vosko, thats EXACTLY right!

 

ErnieT - What type and size, if any, restrictor for the oil inlet to the turbo did you use?

Thanks,
Jim

 

I'm just waiting to hear from PFS as of now. I asked them to measure the WG so I should know if it's the WG. Only wack thing is I don't have my invoice anymore and SR seems to be missing my infos in their database...

 

what size WG did you get with your Stage 2 kit ? cuz I bought mine after you

 

i am using the hks 50mm with mine. if it is indeed the same turbo i spent $900 through sr rebuilding it. what a bunch of ******* crooks.

 

I got the HKS 50mm with my kit.

 

thanks guys!! ..I'll keep a note a that just incase mine is 40mm

 

yup !! come to find out..my WG IS 40mm

I'm going to ship it back to them today and see what they can do

 

I wouldn't buy anything from SR Motorsports. Very shady people.

 

true.
