my fuel pressure tester was leaking slightly when i quickly checked the pressure before i first tried out the new motor .i tried to get a new seal for the connector but no luck so i bought a new one .hooked up the FP tester and found out i was 9 psi light at idle .fixed that and went for a run and had almost no KR showed up on the scan , and i deliberately drove to induce knock .so i might not need the new injectors .it is still cold up here most of the time , worst april in at least ten years , so i will have to see how it runs in the heat but so far so good .

i have been trying to clean up the look of my charge pipe and got a few things installed to hopefully make it flow better and improve the looks ....



i found some used 40 lb injectors so i am going to put them in when i get them .i have now run the car up to 7000 rpm with no ill effects and the scans look good so i am ready to turn up the boost to around 10 psi and see how that works out .

put on a manual boost controller today and i am slowly increasing the boost level .i am up to 9 psi and starting to see an increase in performance .still running the old injectors , scans still look ok but i may have to go to a larger water meth injector nozzle .i keep turning up the boost and scanning to be safe .

when i put on the 20G i had to cut this hole to get it on .it only actually sticks in about an inch .

still waiting on the new injectors , but with a bigger water meth injector nozzle i have been running 10 PSI boost with no recorded KR on the scans .i think i can safely go up to 12 PSI even without the bigger injectors ,i have put on around 2000KM on the new motor and the only problem so far is a small annoying exhaust leak .it goes away when the car warms up after about 15 KM .i havent had time to track it down but i think it is on one of the bolt up joints on the cat convertor .

so i still am waiting for my 40lb injectors .turned the boost up to 12 psi and thats 2 psi too much for the tune i am running and the present injectors.in the upper revs it seemed to lose power and ran a little rough so i backed it down to 9 psi and it is smooth again .i did not bother scanning at 12 psi , i could tell it was not right .fixed the hole and insulated my trunk so now i can take grocerys home without having the food cook on the way home.

did a mild rewrite of my tune .by lowering the PE table AFR to 11 accross the board i can now run 10 to 12 psi even without the new injectors .i have the new injectors but it has been to hot too work on the car much .i also raised the PE enable to 2500 rpm up from 0 so that it does not kick in when i am just cruising around .i have had no problems with the new motor so i am quite happy.i have been running it fairly hard to make sure all is good and no problems .this winter i am going to work on the body , got some new parts to put on and then send it for paint .random pics:

took the car out for a 0-60 run and scans today .i only did one run and the time was 5.74 .i have done better than that but i decided to not push my luck .when i really let it rip the car is very loud and attracts a lot of attention .scans showed that i was pretty lazy shifting and that cost me about .3 seconds .launch was good but not great .need some practice .no KR on the scans and charge temp only hit 25 C with an outside temp of 16 C .i am still just running 10 psi boost and i have not put in the new injectors yet .i can safely go to 12 psi with what the scans are telling me but i am at the point where the car is more than fast enough for the street .if i put the new injectors in i have to change the tune to suit them so i think i will wait till spring to do that . i could also bump the timing up a bit .at high boost , wide open throttle situations , it drops all the way down to 14.5 degrees and with no KR showing there is room for improvement .

my next project for the car is to install the shocks i have always wanted on the front of the car .these are off my stalled lotus 7 project :


these are HAL shocks from QA-1 and are much better than the small body carrera shocks i am currently using. they use the better 2.5" OD springs in lengths up to 10" .the spring shown is a 7" 350 LB and will not be used .the other spring is a 10" 250 LB that i could use but i think it is a little light .i am going to have to mod my held tubular arms to make these work , maybe even lengthen them .my car corners really well already but i want it to be the best cornering car on the road.i am going to modify the rear suspension to add upper control arms and eliminate the struts .this will get rid of the bumpsteer and correct the lack of camber change through travel that plagues most strut suspensions .i may add a rear roll bar but i am not covinced it is needed .the other things i am going to add will be electric power steering assist.the car will feel much better with lighter steering .getting willwood front 12" brakes that are for the subaru wrx .these will not fit a cut down stock hub but will fit my street dreams hubs .wilwood part #140-9193 .these are 5X100 stud pattern .should fit under my 16" wheels .i will have to make my own adapter plates but that is not a big deal .

going on a little road trip this week .heading to cincinatti to see the Bills play the Bengals and then heading down to the tail of the dragon and whatever other twisty roads we feel like trying down there .i was thinking of taking my Gtech but i dont know if it is legal down in Tennessee and NC .up here you can not use anything that hangs off the windshield .anyone know? would be nice to see what cornering force i am generating but i dont want a ticket .

I would love to see your ecotec swap! I live close to Cincinnati, and could meet you.
