Engine and trans installed

WTF, did you paint that block??

Hasn't this been covered already?

What about the inadequate ground for the fuel pump?

HE DIDN'T WIRE THE FUEL PUMP!?

Chris tuned my car today and made 309hp at the 15psi (wastegate spring). I think thats pretty good for $2.60 E85 fuel.
Before I was running C16 race fuel, which costs about $15 a gallon, and I made 319hp at 24psi of boost.
We were going to turn up the boost but after a compression test we noticed one cylinder was a bit low. We decided to leave it alone until I get the issue resolved.

Do a leak down test. Where did you get E85?

1991civicsi · « **Reply #184 on:** June 24, 2010, 11:06:20 PM »

I'm going to try and pick up a leak down tester from HF. I am pretty sure it's the valves not properly seating, because I just honed and re-ringed the bottom end.
Chris had 10gals on hand from a local gas station near his shop.

So whats the update?

I ran an 11.9 granny shifting at Raceway Park on Sunday. Car runs well and I hope to get some more seat time during the season at test and tune days.
BTW outside temps were over 90 degrees.

What kind of trap speeds were you pulling?

Stop granny shifting

Compression test today was bad news. Leak down test shows exhaust valve in #3 cyl needs to be checked. Gonna pull the head tomoro. Maybe its time for some Ferrea valves.

Update? Any thoughts of switching over to a 86-89 d16a1 trans?

I have 2 cable 5speed D Series Si trans. in good condition. One has MFactory LSD installed, and it works beautifully.

As far as he engine, not so good. I couldnt get consistent compression test results, so I bought a leak down tester. The tester revealed exhaust valve leakage. I pulled the head to find the guides were worn and needed to be replaced. Im waiting to get it back and put it back together and do another compression test to make sure the bottom end is tight.

In the meantime I sent out to have the block you sold me sleeved by Golden Eagle.

Nice hum are we looking at a 500+ hp build in the works?

1991civicsi · « **Reply #194 on:** July 13, 2010, 11:22:34 PM »

The turbo is good for over 500hp, but Ive been wanting to sleeve the block for a while now.
Once the motor is together, I want to turn up the boost and see what Chris can get out of it.

Joseph Davis · « **Reply #195 on:** July 13, 2010, 11:29:50 PM »

You should see if they can powdercoat the block for you.

I am still waiting for my head to come back from the shop. Dennis has been swamped. Once she is back together I wanna up the boost.

Are you going for over 400hp now?

1991civicsi · « **Reply #201 on:** July 18, 2010, 09:07:00 AM »

Because I have no cage, I would like to run 11.6 while pedalling.

1991civicsi · « **Reply #202 on:** July 26, 2010, 09:24:41 PM »

I took my head back from the machine shop b/c he hadnt worked on it since he was too busy. I have since lapped the valves and did a leak down test. The results were less than 15% loss in Cyl #3.
I will put everything back together to up the boost and get back on the track before the season ends.

Went to Island on Wednesday and ran a 12.1 in 90 degree heat. Car got hot so I let it cool down and ran another 12.1 which resulted in car running very hot. Coolant overflowed from the catch tank and I went home to work on a solution for the overheating.
I gotta find a spot to do some test runs without traveling so far.
I'm gonna head to HF to pick up a laser temp gauge to see if I need to do some changes to the cooling system.

That doesnt sound good. What does the data logs show?

Joseph Davis · « **Reply #205 on:** August 07, 2010, 10:15:52 AM »

Headgasket, or too much timing. Regardless, it needs a headgasket now.

I retorqued the headgasket. Im gonna see if it overheats again. If it does I will mill the head and replace the Head gasket

1991civicsi · « **Reply #208 on:** August 09, 2010, 03:04:22 PM »

Thanks for the replies. Because I know nothing, I had the timing advanced 8 degrees. This was because when I assembled the head I zeroed out the cam gear to index the motor.
When the car was tuned the cam gear was retarded 4 degrees.
I'm going to move the cam gear and take it to the track to see if all is well.
