Got a few expected issues with my 99 GSX.. Just did a bunch of work to it, Head gasket, timing belt and turbo swap with a rebuilt HMI Evo III 16g, IC piping, hoses, put back stock fuel injectors and MAF for SMOG here in CA... I started the car for the first time today and it fired right up but during my test drive i noticed a few things.
1. Fuel Cut at around 5500 rpm
2. Air fuel code P1103 pops up when fuel cut happens
3. Idle has slight surge sometimes from 800 rpm to 1200... When checking with light Timing mark is moving up and down when surging
4. Not great high end power, better low end.
I have "0" porting done to anything on the car...
When I purchased this car it had a bunch of mods (listed in my profile) on it, so in a way im down grading but still keeping some of the mods.. I had a SBR G50 50 trim turbo before..
I ordered a Boost Leak Tester a few days ago just incase I have boost leaks..
Im wondering if I have vacuum hoses wrong to my evo wastegate? Basically Im just using the stock vacuum routing of the hoses except im not using a "T" that went to the T25..
I have a Aermotive adjustable fuel pressure gauge, and it reads 40psi is that too much for stock injectors?
Also I have something stupid set up to hopefully pass the LAME (visual) smog inspection part of the test .. I am using the stock air intake,Air filter box and MAF. but on the top of the air intake it has the large 2'' or so spout that hooks to the stock IC piping.. I have the stock IC removed from the car and I have a FMIC..
Anyway i just plugged in the stock BOV to that spout with nothing hooked to it on the bottom ... from the top it looks alot more stock.. underneath the stock air intake I have a Blitz BOV turned upside down in the FMIC pipe and its out of sight ... Im wondering if that stock BOV that I hooked up for looks is giving me a massive boost leak at 5500 rpm..
As soon as I get my 2012 tags.. Im yanking out that stock air intake for my Injen, installing my 680cc injectors back, installing my new Wally 255 fuel pump, ordering a boost gauge and wideband, getting a fuel management system, and installing my MBC.. But till then im gonna try to smog it and see what happens, oh and I removed my 3" downpipe and installed my stock DP with cat..
Is there a better place to get vacuum from to run to my wastegate than how I have it set up? I dont have a nipple on my FMIC piping or on my J pipe..
