My 3.8L engine build - Florida's Mitsubishi 3000GT & Dodge Stealth Community!

ruben2566 · 04-09-2009, 11:58 AM

As some of you may know, i've had a new engine build in the works for a year now. I didn't want to jump the gun and say too much about it because there are custom parts made that could not be finalized until i knew they would all fit together in the block and balance out.

Now that i have the custom pistons made to my specs, the rods modified to fit the application and the crank modified, nitrided and polished, i can say it's a 3.80L light weight rotating assembly. I had the piston tops coated with a heat barrier and the skirts with a dry film lubricant. The piston pins are H13 tool steel and are casidium coated to prevent galling in the piston bores. They are a larger diameter than stock for added strength yet lighter for more efficiency.

I won't give specific weights or dimensions so someone won't try to copy and make money off of someone elses hard work, but i can say that if this engine had to compete, it would have all the best parts available.

I am building it to keep up with all the modern sports cars coming out at a fraction of the cost. It's not going to be a dyno queen, or a drag car, i already have one drag car and that's enough to keep a crew busy and send you to the poor house. It will be a daily driver, just a badass one!

I still have to make many parts, the headers, exhaust plumbing, intercooler plumbing, modified sidemount intercoolers, engine mounts, modify the oil pan, brackets for the accessories, i made adapters to relocate the oil filter assembly.

I know there are others building engines for different purposes with off the shelf parts, but i always like doing my own thing, because it's my hobby and it makes the project more interesting to me.

Here's pictures of some of the parts.

This is going to be a fun ass street car! What rods did you modify? What turbos are you going to run? Have any pictures of the machined block? Specs?

Master · 04-09-2009, 01:59 PM

that is just sick is going to kill any lambo out there or any other car a custom lightweight 3.8 TT AWD

BUT still what turbos are you going to put in there the td05s
but i think it will be faster easier and reliable to make it single turbo
