well my engine is blown, looking to go with fully forged internals now. need to find a shop in cali to do this if anybody knows of one, post it please. other than that i know i can get a fully built one from jbp, but that can take a few months. is there anybody else out there that is building lsj motors?

 

Is yours the 2.0 SC? If so you already have forged pistons, rods, and crank. Even if you have a 2.4 you still have forged rods and pistons! And those pistons are good for around the 400hp mark. I'd say get the rods polished and ballanced, have the crank spin ballanced, knife edged, chamfered, cross drilled, and relief cut. That crack and the rods will be good for at least 600hp! As for pistons if your dead set on new ones a nice hyperutectic set will do nicely and with out the possible knocking of forged pistons. Now I'd also run a set of total seal rings so you squeeze ever pony out of it you can! Keep your ballance rods as the car will be street driven and I'm sure you want it to last right? RIGHT! Port and polish the runners on the head, bigger valves with a 3 angle valve job. See if you can find titanium valve keepers and locks and maybe valve springs too. Remember get rid of any un sprung weight so it can rev like a ****! I'd run a nice set of stage 1 but no more then stage 2 cams. Then port the intake to match the gasket rubber band things closely and also port match the header flange to the gasket.

I think thats all but if you have any more questions feel free to ask.

Hope this helps.

 

Jack there are no forged pistons in the LSJ, 2.4 or 2.2

 

nope cast bitches lol.

I'm sure there are many shops in your general area man, just do some research, hit up some car shows or check out local speed shops.

 

No I said in the 2.0. I thought they did? Now I know the 2.4 doesn't sorry if I wasn't clear.

Are you sure the 2.0 isn't running forged pistons? I could have sworn.

 

nope mahle hypereutectic... damn too tired to spell

 

WHOOPS! I made another boo boo! The 2.4 uses cast rods not forged! Damn memory! Anyway cast rodes as long as they're polished can handle the same stuff as the forged ones can.

 

thanks jack, but yeah pistons are cast for the lsj. i plan on doing most of what you stated, but i'm looking for a shop to do it for me. thats my main issue. i found out whitfield racing is here in so-cal though, so i might be in for some good luck on the build.

 

Ever heard of Jasper Engines and Transmissions? You can have them build it for you custom ANY way you want it! They build NASCAR engines so I'm sure they can handle a little 4 banger. That and I had them build my over 600hp 427 Pontiac big block and they did an AWESOME job!

 

where they located, and how much did they charge you?

 

Jasper In. They have an exchange service thru shops all over! You'll have to check around to see if they're on the left coast. I worked for them when they did my big block or I NEVER would have been able to afford it. It ran me right around $10,000 but if I wasn't an employee it would have been over $40,000! I had TONES of machine work and an all titanuim valvetrain and the rotating ass was done at the NASCAR shop in the Carolinas and ballanced to 15,000 RPM!!! Not that it ever saw it tho. I had all 8 cylinders bored out stupid big and all 8 sleeved and then the sleeves bored to except 455 pistons and kept the 400 crank and rods and TA DA! That yeilds about a 427 ci engine. Man would that thing scream! All roller valve train (lifters and rockers) with titanium keepers, locks, and springs.

I miss that car

 

wow that motor sounds like a beast . but i think there a bit out of my price range. not looking to spend more than 6 or 7K

 

I said that once too

 

thats why i'm afraid to go with jbp, cost and time

 

JBP's cost is fine. They are actually the cheapest part of my project, and Mev is great to work with.
The wild build they offer is based on my engine build.

 

yah i was looking at the mild build, but i don't like the rods they use. oh and the "please allow 1 to 2 months for your engine to be built". thats the real reason i won't go with them. i would love the wild build though, just don't have the time or money, my car is a daily driver.

btw when they say crate engine, does that also include a head or not?

 

Heads are not part of those builds.
What don't you like about the Pauter rods that JBP uses??
The 1 -2 months is because of some ******** project taking up most of JBP's time right now

 

wonder who that would be

 

it's the sportsman rods i don't like, if they built the mild block with the cross beam 4340 cromoly forged rods, then i'd be happy.
all in all i figure i could toss them a few more bucks to upgrade to the rods i want, but the time factor still has me.

 

Likely the same guy who will rep you when the system lets him
They are an I beam rod. As well they now have access to H beam rods and they are all 4340 .

After looking at JBP's site I could be wrong on that sportsman rod but it is easy enough to get them to use the better rods.

 

well i may still go with them, if what i'm doing now doesn't work out and i get enough financing/reenlistment bonus. the biggest thing i want is those wiseco pistons.

 

I've checked into the engine prices JBP offers and that is one thing they are competitive with, they are very competitive with the prices considering what it is you're getting.

8.8:1

 

yah thats sooo true. i have been spending far to much time on there websight last couple of days for that reason

unfortunately it's only 8.5:1, i can live with that though, when the turbo is in

these are the rods i want.

 

900 dollars for 4 rods is pathetic. You can get 8 for 500 these days. Just use custom forged pistons and use the stock rods.

BTW - I paid 582 for my custom 8:1 SRP pistons

 

Jimbo how did you blow your motor?
