Nice write up Carmela ! .
My 2.3 stage 3 has been faultless . Runng 750 bhp for over 18 months and only used on track .

I can recomend JAM 100% I'm in the UK and shipping was all sorted by Carmela..

 

same for me ,running ur stage 3 short block along wid ur stage 3 cilender head .
im very happy .
i 100% recomend jam .

 

impressive, even more so that you guys are located in MD

 

im in pakistan ,i got my stuff all the way to pakistan ,the stuff was well packed and carmele took a gud care booking the stuff on a very nominal charges .

 

damn some of those machines look like antiques!

jk, thanks for the write up

 

Great Job, JAM!
Finally, some good info about how hard you guys work to make sure everything is clearanced and machined properly.

Attention to detail, understanding the mechanics of these engines, and the right selection of parts that go into the build is extremely important. You have outlined points of comparison that people can now reference toward a price point.

The level of work involved to have a REAL blueprinted engine is worth every penny and every minute spent. Keep up the good work!

 

Nice write up JAM it was great to see the work that goes into building a shortblock. I cant wait till my 2ltr stage 2 is fitted and run in.
Also this is one of the reason's I wentt with JAM over other shops they are the only place that do all their work in house

I also liked how they had no problem answering all my questions unlike other shops where I got the impression they felt they were too big to be answering my questions.

Heres my lovely block I recieved from JAM last week.

 

Very nice write up Every time ive called there you guys have been very helpfull and fun to talk to Keep up the awesome work

 

Most everything you listed is included in one of our build sheets.

As far as I know, we are the only shop modifying the oiling system in the Evo blocks. We are also the only ones modifying the balance shafts to this extent. I've seen lots of blocks built by other shops advertised to be "blueprinted" and they haven't even been decked. Many shops out there assemble engines without thoroughly checking the parts before they're assembled. Often times, used cranks are installed without being checked over to make sure they're straight and not cracked. All of this is what goes into a TRULY blueprinted engine. My best advice is to ask whoever is building your engine to give you a list of everything that is being done. If they're leaving anything out, find another shop.

Often times it's not only what's being done to the block, but HOW it's being done. For example, we've spent countless amounts of time and money developing a honing procedure specific to the 4G63 which is unique to our builds. The proper cylinder wall finish is one of the most important aspects of a build because it affects everything about how the rings seal and wear.

Also unique to our builds are the balance shafts. We keep them in all of our 2.3's and believe that is the reason for the smoothness and longevity. As mentioned in the original post, the shafts are modified and we use coated bearings.

 

Thank you, Paul. Keep us updated

And yes, were are a machine shop. All we do is build engines and it is all done in house. We're a small shop with just the two owners and myself and we strive to give the customer exactly what they want. We speak with each customer at length to determine what their goals are for the build. Each build is tailored to each individual customer to fit their needs and goals.

 

Thanks Nick!!

Exactly my point. Call some other shops and ask what you're getting for the money. You'll soon wonder why they charge so much and get so much less.

 

As one of JAMs happy customers I can say after racing one of their strokers with over 500WHP for almost 12 months I recently had the block compression tested and leak down tested and it is completely flawless. Thanks to great workmanship and great tune (thanks Mynes).

Now I have moved to a larger turbo and plan on racing the block at over 700WHP for another 12 months. I recommend them to everyone I meet. Also Carmela you may get a call from me to build a 2.0 since my car seems to be heading down the all out drag path.

Oh I have one of their stage 4 heads, amazing, I can say it netted me an additional 40-50WHP compared to a car with the same setup.

 

Thanks for the info Carmela, The attention to detail It's amazing, and also the customer care.
Maybe that's why almost every tuned Evo in Chile uses your engines, and never heard of a problem or complain.

Wow, its a good thing the guy in this thread tried to tell everyone there is nothing to be gained by hand assembling and blueprinting a Japanese built engine...

Very nice JAM, very nice view into your assembly methods.

 

My mechanic was very impressed with the modified oil ways as you dont always see that being done.
