you should use the data logger and AFR meter try to put more boost step by step,then check the AFR, don't go too lean, and with the dataloger check the injector duty cycle. the safe point if You see "injector duty cycle" between 85-90 % and don't forget water injection & race gas will allow You...

check this link Pure Tuning the price is reasonable.i prefer the hx35 holset , it is 550 whp fast spooling turbo with under $1000 price :D or if you dont mind with turbo lag and looking for better top end, then go with hx40 its 600 whp class turbine

Currently using Tial on Supra and HKS SSQV on EVO, I think they are Good products, No Leak after 2 year Love Tial , better sound hahaha

Hi.. please check the sensor, whether is dead and please make sure to put sensor in 9 to 3 position, it helps with condensation problem and don't put the sensor too close to the turbin outlet or the sensor would be fried g luck

and also try to lean the AFR before it start to spool. usually more timing down and lean AFR helps spool up G luck.

I guess it's really Hard, unless You have deep pocket, why don't U use EVO ?:D It's still Mitsubishi :thumb:

any picture ? it's look awful

Yup evoscan and a wideband should be good enough, if you don't run extreme AFR, just run the safe AFR like 12,5 during spool up and 10,9 under full boost BUT if you want to use the race gas and lean out the AFR, You'll need this EGT the leaner the AFR (till around 12,5) = More Power = More...

The 42R is way too BIG for Your Engine It's gonna Lag like Hell, unless You Run on Nos or Compound setup and Heavily modified engine Currently I'm running this 42R on 2JZ,3.4 stroker, spool up at 4700 RPM Maybe You should start researching and ask Yourself, what's Your Goal

You can try to lean out BUT You didn't know where to Stop Yeah , Tuning without Wideband gonna be like walking in the dark, LOL You Have No Idea what's Going on, till You Hit something Don't Do That Dude.., Your Engine is much More Expensive than A wideband

Hi any result from the cam ? I think Rough Idle gonna be the main problem, WOT should be OK G Luck

I think Jun 272 is the Best

after pay, you should got an email with pin/serial number and link to download it If You got nothin, try to contact the vendor, just give him your mail address again,and soon he will give You a link and the serial number may help

Definitely, - Exhaust Diameter - Exhaust Length (from engine - Turbo) - Bend, No sharp bend - Equal length from cyl 1-4those will affect how turbo spoolin large diameter exhaust is good at high flow, but usually lack of mid range torque/spool up so it depends on engine/turbo setup

example please ... yes there are a lot of turbo out there

or maybe You can try compound setup, using td06-20G with gt42r :D

using 280 cam will hurt Your idle and drivability, especially when Your car is daily driven, just stick with 264 /272 if you like the midrange power or 272/272 if you prefer high Rpm trust me, i used to use 280 cam on my 4g63 :D, now I'm quite happy with 272/272 from cosworth, combined with...

4G63T EGT should be around 800 deg C till 825 deg C on WOT
