Cant find a reliable LSX builder. Anybody know of one? - Lateral-g Forums

69/RS · #1 03-02-2012, 12:20 AM

I have been looking for a reliable engine builder for a while now. I have called a bunch of places, talked to builders on the phone, even met people in person.
These builders either don't respond with an estimate after being asked at lease twice or there bid is almost double what it should be.
I was refereed a builder by the shop working on my car and they said there communication was poor but put out a good product so after communicating with them....poorly for the past 2 month .I decided to deposit $27K into the builders account but they will just not respond to my final 3 simple questions. I cant get them to respond when I'm about the give them a ton of money....I can only imagine what it would be like if they had my money.
I need this engine done pretty soon and looking for a guarantee build date.
I have the build sheet to make there job easier. Looking for a turn key built 427 LSX motor with F1R pro charger. I need everything! All the way down to the harness. Thanks in advance for your advise.

Where you located? Give JR Competition Engines a call in Escondido CA 760-745-4540. Talk to Shaun or JR. They will take care of you.

Without a doubt, Jason Pettis at Pettis Performance in Southern, CA. He is one of the sharpest engine builders on the planet with power adders. I found him to offer excellent service before, during, and to this day. Two years AFTER he built my engine.

I'm in Nor Cal.
I talked to them and ask for an estimate 3 times on 3 different occasions.
Been to the shop and met both of them. Both nice guys and look like they know what they are doing but after asking anyone for an estimate more then a couple times and not getting it make me a little concerned about paying for an entire motor in advance. I have read of horror stories on some forums and don't want to be one. Thanks though!

I'd advise you to call Jason for the best results. He has always answered my emails but it can take a few days vs. a phone call. His estimates are extremely thorough and he had my engine on the dyno by the promise date.

Here's some photos of his machine work:

You can also talk to Wegner Automotive. They do a lot of development work on the LSX platform. They were the official Spec LS builder for the NASCAR touring series as well. Call and talk to Casey Wegner. They are excellent to work with. 920-394-3558. They are in Wisconsin. Don't worry about that at all. I am in Pennsylvania and we got ours with no issue.

Wegner Automotive is a LS specialist all the way. They are responsible for and develop alot of stuff that GM uses today in the LS world.

So the builders don't know what it costs to build the motor you want? Or is it that you just don't want to pay what it costs to build it. If the people in the business are telling you what it costs to build the motor... and you don't like what you're hearing... I'd say it may be you that has to figure it out.

Billy Briggs Racing engines. He is very well known and reputable, just finished up this LSX for Pro-stock motorcycle rider Eddie Krawick. He's up in Michigan, but is the best and you won't be disappointed. Do a google search on him if you are leary.

If you are set on a pro-charger Steve Morris race engines is the place to go to. He works hand in hand with Procharger doing R&D work and recently released the Provolute which has had some serious gains in HP just by bolting it on to the inlet. He has a website and its...he is also a top notch builder http://www.stevemorrisengines.com/
