^^^thats my point he's going to be putting down well over 300hp with this build. My spec stage2 was just fine on my 74 till I threw the 75 in and it took a hole 2 days for my 75 to tear thru it.

lookin good

True i was there when that shit fucked up. We did a few pulls not even 100% tune. Just a base tune to get it started. Could not hold the raw power.

Keith- what year eclipse ecu are u using? And what year big map version? i belive the more stable one is the 01. Club 3g is having problems with other ones because they are a few noobs that dont know what they are doing and start chaging values like crazy.

[keith6110]

I'll be getting the spec stage 3 clutch. Tj's seemed to hold up fine to his 530whp.

I planned on running an 04 eclipse gts ecu.

I can't find any solid info on mafs and I'm not sure the 501 maf will be able to handle the 12psi I plan on pushing with this hx40.

So this gives me 2 options. The evo 399 maf or go with a speed density setup. For tuning purposes, I want to do a maf for now and maybe speed density later. I was able to tune my brothers car enough to get rid of the backfire based on the evoscan results. I was hoping to be able to do my car the same way.

I have a feeling I'm going to put this setup together and not get it to run right when in boost. I know, cross that bridge when we get there lol.

[Galantman03]

Speed density FTW!

[keith6110]

daamn... I have no idea what I'm doing for speed density tuning either. I'm only familiar to the maf tuning. This sucks.

[Galantman03]

Well I plan on using it just because with the new tephra mod it can adjust based on barometric pressure. But thats on the evo 8 ecu

[Isaurio]

Bro. Eclipse gts maf i think is 462 it flows same as the evo 399. 399 it flows a little more but not much. Thats is the way to go for your setup.

Not a good idea to use speed density right at the bad specially for breaking. Since you still going to change parts along the way with speed density you have to tune every time you change something on the engine. Go MAF then why is no more mod made go with SD

[keith6110]

Bad news, then some good news lol. I wish I was able to find the answers on my own, thanks for the help guys.

Eclipse gts maf is 482*

Thanks bro.

[Isaurio]

Yes 482. Thats it. Lol

[keith6110]

haha, google was pulling up a mitsubishi 462 maf.

We'll talk more at the meet up, hopefully it will clear up some of the questions I have.

[Rach3T8G]

Here's a little something to look forward to

^That's Justin's 3G that I was mentioning on the previous page. I rode in that thing last weekend and it was amazing, even on only 4psi :)

[Rach3T8G]

I've been following his build on C3G even though i don't post there anymore. Makes me want to go boost.

[keith6110]

That.... Is awesome! I guess someone else beat me to the hx40 on the sohc v6. I guess the only difference is I'm starting with 12psi lol. Maybe I'll contact him about his tune.

Makes me feel better though, nice post man.

[Isaurio]

Im going for 20 psi.

Start low for break in keith. 5 is good to start

I forgot to bring my dslr to the garage, so cell pics will have to do for now lol.










Piston custom orders specifications




If you can't see in the picture, I had gotten the 399 maf from an evo. Came with an hks adapter so I can use a 4in intake pipe lol.

The pistons are a 10:1 compression setup.
I was worried about the stock rod fitment for these piston pins. They fit perfect, I highly recommend the kit I ordered if you plan to build the 6g74. It came with all gaskets, MLS head gaskets, and engine bearings/freeze plugs.


I'm planning on giving the block a pretty aggressive hone to help with the piston clearance for when the pistons get hot and expand. From what I read, the cast pistons don't expand as much as forged pistons. If done incorrectly I guess it can cause engine damage. So this seems like a pretty important step when using stock bore pistons.

You shouldn't be touching that block by hand, it all needs to be done at a machine shop. It takes a very expensive machine to hone the cylinders to your specification (they will do it piston for piston, exactly) along with rehoning the rod journals for the ARP rod bolts (which is a guaranteed must) and rebalancing of the entire rotating assembly. There is much much more that goes into the building of the short block, it is not as easy as simply putting the pistons on the rods and running a ball in the cylinders. Technically you can go about it that way but your engine will not last long or perform very well.

really? i understand what you are saying but this summer alone i have rebuilt 2 6 bolt 4g63s that are now over 450 AWHP one with a PTE 6152 and the other with an FP3065 both over 28psi and daily beaten. the way you mention will yeild slightly better results, but i have seen machine shops mess up plenty, even the best shops. i do completely agree with having the mains cut and honed for the ARPs, but honing the cylinders yourself isnt bad with some ATF and a hone and as long as u dont touch the bearing surfaces by hand you should be ok. for my built 2.4 i honed the cylinders and decked it, u did have the crank polished and the mains cut at the shop tho
