AWESOME. And I bet you suprised him for sure.

He was cool. We pulled off a couple miles later and he threw me a thumbs up, and yells "Damn! I want one!"

Haha sure you do, pal. But thanks.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Too fun! and that was definitely not Mexico! I have driven that road too many times to know better! lol But I'd definitely like to take a run against you in my '67 when I get a better tune on her if you'd have for it!

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

I'd race John Force if he wanted to get down ;)

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Racing is fun. Racing John Force would be a He!! of a lot of fun. Racing you would also be fun! FUN. That's what we are here for! Let's race! That would be funny. Ha ha! Baby sounds nice!

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Looks like when i got greedy on the rough tune, I hurt 3 holes. Oops. You'd think it was my first rodeo...

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Jeez! Do 6.0s grow on trees up there? :lol:

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Pretty much. Lol.

As of right now, kicking around in the shop I have:

Two LQ4s
LM7 5.3
LS6 5.7
L33 5.3

Never hurts to have spares :)

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Do you have a milage range you like to stay within? 50,000 to 100,000 for example.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Nope, I ain't skeered of pretty much any LS. I've never got one from the junkyard with less than 70k on it, and most of them have been 150k or more. To hell and back.

It figures of course that the first LS engine failure I've had was with the 70k mile 2007 LQ4 that is in the blazer now...

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Where did you find your bulkhead connectors? I have been looking all
over for one like that. Thanks

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Loved the Video. Sure sorry it was so expensive.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Got them from the Cat dealer. You will also need a deutsch pin crimp tool and a whole tons of pins and sockets. It was f'n expensive all said and done, but super clean.

Caterpillar Plug 9X-0401 $46.39
Caterpillar Receptacle 9X-1343 $42.46
Caterpillar Receptacle 214-4208 $80.68
Caterpillar Plug 160-7689 $34.01


Haha thanks. Although the more I dig into it, the more I think that much of the damage was done early on in the tuning process, before this stunt with the GTR.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Looks really clean. I will probably go back to the mil-spec route, but I will see if my buddy at the cat dealer can hook me up. Thanks

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

The round mil-spec stuff is nice, but I needed a connector with more pins. I used one 70 pin bulkhead for the engine, and another 40 pin for the transmission and wideband, water injection, etc.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

How do you like the handling with that front end? I am also doing a unexpected motor swap this summer.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

I like it a lot. Rides nice, but I wish it would have come with a heavier set of springs. I have them maxed out for ride height on the adjusters.

Might go back this winter and put some 500 lb/in springs in to replace the 450s it came with.

What happened to your motor?? F'n hot rods....:lol:

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Do you have some sort of boost retart setup in your ignition? If so what do you have it set at and what are you going to change on your new motor. Also, how many pounds boost?

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Boost timing retard? The answer is "definitely kinda". :lol:

The megasquirt has a 3D timing table. Load in kPa on the Y axis and rpm on the X axis with timing values in the cells. I can set it to anything I want it to be. This one isn't mine, but it's an example of how it looks.

http://img715.imageshack.us/img715/1293/spark.jpg

I'm not changing anything on the motor...I've had really good results with turbo stock shortblock LS engines in the past...I just got stoopid with a rough tune. We were still sorting out a couple of random megasquirt issues, and I got greedy and beat on it too hard before I should have. Also, the knock sensors were not enabled yet. :mm:

So to answer your question, I'll have more patience next time.

Boost was right around 14 psi. Gonna back it off to around 10 until I get everything sorted out, then switch over to E85 and go to 16-18 psi. Shooting for 800 rwhp out of this setup.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

WOW havent been keeping up on your build lately, But WOW its nice to see it all together and that video was cool. Sucks about the motor but sounds like a minor set back for you. Love the conversion your build thread is a must read for anyone wanting to convert!! thanks for all the info and sharing this build with us.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

This is so cool! The video is awesome and sounds like a minor setback for your skills...great looking blazer so far.

Rob, I emptied out my inbox. Fire away.




Still been too busy/lazy to swap out motors, so I've been beating around on the hurt one.

I set up a local hot-rod cruise every week, and last night I got a couple of nice kills via some shennanigans on the cruise. :metal:

First up is my buddy's 996 911 Turbo. It's got a tune and exhaust and some other goodies and has been converted to RWD.

Got him from a 40-120 roll, and was reeling him in from a dig until my tires went up in smoke. :waah:

https://sphotos-b.xx.fbcdn.net/hphot...39851762_n.jpg


Next up was another buddy's 2013 SRT-10 Viper.

We went from a 50 mph roll, and from a dig, and I walked him pretty hard during both. Needless to say, I'm pretty happy how the blazer is running...even on 3 hurt holes ;)

Nice kills, we need some videos of it

Sadly I was by myself, and they were impromptu races...so no vid :(

However, there were about 10 witnesses behind us, lol.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

hows the bad cylinders holding up?

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

So far so good I guess. Haven't had any chunks blast through the turbo yet...haha.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Can you share some info on ms3? Does it have iac control? Do you need iac if not running ac? What came with ms3 I really like those bulk heads. Thanks.

Nice job should run real well when ya get a new bullet in her..

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Yes, it can control either a stepper IAC, or a PWM IAC. I'm using the factory stepper IAC with my setup, and yes, it is helpful even without A/C.

Everything you've never wanted to know about MS3.

The bulkhead connectors came from the local Cat dealer.

Thanks. Got a new custom turbo cam from Tick Performance waiting to go into the new engine. What's in there now is "ok", but i wanted a cam matched to my setup.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Do you happen to know the part numbers? i called local CAT dealer and they were lost. the ones they did price me were 45 for male and 45 for female.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

dream build! right on!

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Hey so how did that Heidt pressure regulator valve work out? I just ordered one after reading that the hydroboost likes 3.5gpm/1500psi and the Mustang rack likes less than 2gpm/800psi. Hmmm, and how did you find out about this valve? I've been searching for days for an answer to this problem until I stumbled upon some obscure write up someone did and then as soon as I saw a picture of the valve and then I remembered seeing it in your build. But nobody seemed to have an answer to this problem, not the place I got the booster from, the company that made the rack, companies I called about pumps, even Heidt said they wern't aware of using it to regulate the pressure after the hydroboost and before the rack. How did you dial it in? Just play with it until things seem to work best? Did you use a high output pump? My understanding is that GM type II pumps put out somewhere around 2.5gpm/1000-1200psi which I'm told is kinda low for the hydroboost. Anyway this seems to be this unknown magic solution to this problem.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

I didn't end up using mine...you should return yours and buy mine, complete with fittings. I'll cut you a deal.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

[QUOTE=Wasted Income;6044987]Well as they say, the devil is in the details. I had more time in coming up with radiator and heater hoses that will work, than I did in the whole hot-side...

Got the downpipe fabbed up. Turbo outlet is 5", and I reduced to 4" right off the flange. I used a band clamp instead of welding the last piece for several reasons. First off, I'm not sure if I want it to exit there for sure, long-term. Secondly, it may be way too loud and require a muffler (which is ultimately did....lol). Lastly, any rework is one less thing to cut apart.

http://i235.photobucket.com/albums/e...ps5aec8bf6.jpg

Had to get creative on the lower radiator hose, since the crossover and merge are fighting for real estate with the hose.
I ended up cutting the lower radiator neck back, and re-welding it...reducing it from 1.75" to 1.5", with a tight bend coming out to clear the exhaust. A nice benefit is that both end of the radiator hose are now 1.5" instead of being staggered. I went with the stainless steel flex hose for the bulk of the lower hose, to reduce the chance of damage or melting from heat.

http://i235.photobucket.com/albums/e...ps1d4e6111.jpg

http://i235.photobucket.com/albums/e...ps35effa87.jpg

Couldn't really go above the frame, or below the frame with the turbo oil drain...so I went through it with a -12 AN bulkhead fitting.

http://i235.photobucket.com/albums/e...ps7fc5c6bd.jpg

Heater hoses were a bit of a challenge as well, since the pass right between the downpipe and the manifold. The waterpump outlet is also very tight to the merge, which required molded hoses with 90s on them. I used a reflective heat wrap that is similar to what we use at work on our aftertreatment modules to shield fuel lines and such from excessive heat.

Lastly here's a quick vid showing one of the coolest features of the Megasquirt. Logging and tuning on my phone, via Bluetooth. Took a little vid while I was burping the cooling system.

Ooops, lol. Was trying to edit that post and ended up re-posting it.....doh.

Anyway, here's an updated video. Still on the hurt motor.....haha.
