just spewing coz its got absolutely NO midrange

the hks2530 is known for its midrange torque so there definately must be something causing your turbos not to start pulling and spinning the wheels as soon as you stab on the throttle.

sorry hud let me clarifiy you need to keep the restrictor as it reduces the size of the hole the air has to travel through which increase the pressure holding the wastegate(act) closed ( think about a garden hose when u put your thumb over the end) Ive read that by altering the size of the hole in the restrictor you can change how the turbo ramps up on boost ie make it spool slightly earlier or later( hpi mag did a build up on a jap spec s15 which they did this on) if your missing the restrictor entirely by using pretty blue hosing instead you may get the problem you have as there is not enough pressure holding the wastegate(act) closed

damn so 1 bar @ 4,000rpm is resonsble..? i was looking at the hks line of turbos for my r32 (rb20) was thinking

- GT2835 pro S

- GT-RS

- GT2530 (KAI what the diff with KAI or not??)

was told GT-RS would be laggy get the 2835 pro and i guess there going to shit aswell so might be looking at 2530 now?? anyone have any ideas on what the other 2 would be like??

I remember reading in some post that the new 2530kai is rated higher than the old 2530 in terms of power...old 2530 was 320ps i think and the 2530kai is something like 350-360ps or something like that...try searching here...

    • I used to have Walbro 255's when they were a pretty common update. (or were they 044? 040?) In any case I had a dirty tank. I thought the tank was good, but I would find the filter would clog in maybe ~50km of driving. If the issue persists, well, your fuel system or tank has crap in it that the pump is sucking up.
    • Hi. Ok thanks for the info. I/we do not know what tune is on that Nistune ECU so it is why there is stock ECU and that Nistune is for later when the car is done. I have guy who tunes Nistune and other ECU so i will then take it to him to see and properly tune for the car   And for the update. On 99,9% it is bad fuel pump. Which is wierd cuz it is like 2 years old(brand new walbro 255) and that filter (also brand new) was dirty.  I was alwaya pumped premium(100) on very good petrol station so i dont know how is that possible...  
    • Dear folks My family members have 4 different cars : Triton 2015 and Corolla 2011 and Mazda3 2012 and Hyundai Elantra 2014 Looking to buy engine oil funnel spill free What I found are are below  https://www.amazon.com/gp/aw/d/B0BBTTJNKX?ref=ppx_pt2_mob_b_prod_image&th=1 https://www.ebay.com.au/itm/145553221359?srsltid=AfmBOoqYBU6Ptw0LU_bAp_k67U3qkF97HHvePkA7iHZw8vUmiwoIRaRr https://www.amazon.com/gp/product/B09X23TCS5?th=1 Is there a funnel with attachment that fits most cars ? Don't mind to spend for a decent quality  Thx  
    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here
