Who is this guy? And where did his grammar go?

P.S.

3.4L stroker kit sounds pretty manly. I'm curious as to what numbers the car will be putting down. Let's turbo it in the near future too, kay?

How much do you think it cost to get the parts and do the stroker upgrade itself?

Looks nice man!

What kind of intake manifold is that? Custom made one?

in his build thread he mentioned the parts were over 3k.

I supplied the core for the crank and an old piston, gave them a mold of my combustion chamber, and specified what C.R. to build to. This crank and piston set is made to work with stock length rods.

Just back from a weekend trip - Thursday on the first drive the A/C compressor pulley came partially off (looks like the bearing burned up) , shredding the belt. Need to get another compressor Monday and begin replacement , not an easy job in that crowded engine compartment.

I drank enough this weekend (went to St Augustine for some relaxation time)to temporarily forget the frustration. Always something with this car...

Can we possibly have any more info on the Coil setup?

They are the famous LS2 "truck" coils with built-in igniters and visible heat sinks on the top. After buying two sets of used Supra coils and finding half of them cracked, I looked for a different (more powerful/more durable) setup. Supra guys are replacing thier coils frequently, at 4-500.00 a set. And I don't need the HK$ DLI.

I bought the set of 8 new LS2 coils with harness on ebay for ~150.00.

I removed the brackets holding the LS2 coils together in groups of 4 and built 3 brackets to mount the coils in pairs directly onto the 2J head/plugs. I removed the rubber plug boots and interior plug contact springs from the (bad) Supra coils and used them to make the GM coils fit coil on plug. I then separated and rewired the GM harness for my application.You can see the setup in the picture earlier in this thread - I'll post some pictures of the brackets and coil mods a little later.

These coils' igniters work just fine with my Haltech PS2000 (use the same settings as the Haltech/Bosch igniters) , and I suspect most aftermarket ECUs will fire them. They work with a positive pulse, firing on the falling edge. I'm pretty sure that they will work with either 5 and 12 volt pulses in - Haltech is 5v...Dwell time can be set to 4 ms or so.

My setup uses direct fire, but to do a waste spark setup you can use 6 coils and pair their inputs from 3 coil drivers, ie, 1&6, 2&5, 3&4. I know this works well as I have done waste spark using these coils driven in pairs on a turbo
LS1 motor.

I got busy and replaced the compressor, charged the system and went out for a drive. The A/C condensor immediately blew out in spectacular fashion. No, I didn't overcharge it. I've removed the old condenser and will be getting a new one next week. Definitely too hot to be driving without my air.

I also was blowing big oil clouds at high revs - After major freaking out thinking my new engine was somehow hosed, found lots of oil in the air filter pipe - Turns out that I don't have a big enough restrictor in the turbo feed line. My .060" restrictor was fine in my old engine but the new one obviously produces more oil pressure. Justin at Comp Turbo says that a.020" hole is right, and is sending the correct restrictor fitting along with a small filter for the oil feed.

I was trying to make the Titan Dyno day Saturday but...

Well, the A/C is fixed and now it keeps the belt on - The turbo oil restricter (homemade from a .023" MIG tip screwed into an AN fitting, then filed down) is installed and no more oil blowing from the turbo, although there is still some oil smoke in the exhaust that I hope will be gone after rings have worn in...Idle and free-rev tuning resumed, and I find that the smoother I get the idle, the quieter my Tilton clutch's rattle becomes. That noise level is very tolerable now - it had me concerned initially. My LS2 truck coils -on plugs- working well. Before I can even pull out of the garage it overheats and the radiator overflow tube starts gushing. Damn electric fan has failed and put a nice mark on my brand new Koyo radiator. I've ordered a new Flex-a-Lite dual fan - should be here this afternoon.

Very frustrating - I have limited time to work on this thing and keep having stupid things to fix.

Delayed gratification sucks.

Getting There...

Finally got my turbo oil feed and cooling fan issues squared away (took Comp Turbo 2 weeks and 2 shipments to provide a restrictor -.014" - and filter) and did did some driving today. The engine was blowing lots of oil from the exhaust and breather, and the restrictor didn't eliminate as much as I had hoped. The quantity of smoke/blowby had me worried that I had a ring sealing problem.

After a few non-boosted light pulls/backdowns to wear in the rings the blowby is gone and I am greatly relieved. Now that oil is no longer affecting the mixture I can begin seriously tuning. I'm very impressed with Haltech's ECU Manager software for the PS2000, especially the VE tuning method. My first try at a base tune started the engine and ran it surprisingly well.

The inevitable small leaks and wiring glitches are fixed and for the first time I'm feeling good about the project. A totally new built engine, reworked harness, unproven coils/ignition system, and fuel management brought so many changes that there was lots to worry about.

I'll do a build thread with dyno when time permits.
