FP? I talked to Hollywood.

'vacuum pulls' can be done on any turbo, I reckon. He knows to leave the injectors the same...he had to borrow my stock injectors the last time around.

**Murlo26** · 05-27-2011

There you go

Wanna buy a black, I'll give you a good deal lol.

**Murlo26** · 05-29-2011

Soooo, thinking of switching a few other things during this build.

What are the thoughts on switching to the short runner manifold from MAP? They used it on their shop evo and made 722whp on it so I am guessing that it flows enough. I am only worried about it lasting as they don't make it in house.

I am almost for sure switching my downpipe out for MAP's external dump one for better boost control and maybe the HKS wga instead of my blouch for a few more psi.

Trying to dial in the "perfect setup", basically a wide ass power band.

MAP short runner = Tomei says a credible source, I wouldn't worry about the quality, plus I am sure they'd warranty it if it ever cracked.

Chris told me its made in one of the Asian countries, I can't remember which one.

It looked quality when I looked at it though.

After looking at my cars dyno graphs with it, it seems the short runner is kinda the best of both worlds. Especially when I don't plan to go for every last ounce of power this time...at least right away. hah.

i'd like my spool to be sub 4k rpms on the new setup and basically whp/wtq to be equal...hoping for 475whp/475wtq area...but will probably be closer to 465whp/440wtq area...but I can hope.

Just got off the phone with Seth @ ERL.

They got the block last week and they have it inspected and ready to go.

So ERL is checking my old crank out that was still in the block, they doubt its worth saving as the one journal is really F'd up...but hey if they could fix it i could sell it for a few hundred profit, worth a looking. The rod that had the spun bearing is getting replaced for sure, ERL said it couldn't be replaced and to me its not worth trying to fix and I didn't want to risk it. They are going to check the other 3 rods but they said they should be fine.

So gave em the CC number and its paid for now and ready to go. Checking with AMS now on my new pistons that hopefully are done or will be done this week. And hopefully ERL can get it pumped out pretty quickly and I get to move on...yay!

edit: I asked about the oil squirters and they said they will try to modify to make them work or just plug them if the modifications don't work. I am leaning towards just having them plugged but I will leave it up to them, they are the experts...my only line of thought was with them plugged maybe my chain when it stretches doesn't rape the squirter..not sure if thats a big deal even.

**Kracka** · 06-06-2011

Chain-stretch won't affect your piston oil squirters, only the one in the timing case. The newer 4B11T blocks don't use the timing case squirter though, since you bought a new block last year I wouldn't be surprised if yours doesn't have it.

**Murlo26** · 06-06-2011

Interesting...

Well regardless the 90mm pistons will probably have oil squirter clearance so they said they would try to modify them but its not a big deal if they have to plug them is what they said so we will see what they end up with.

My new pistons are just about done. JE said they are shipping this Wednesday, so that's good news...stuff is moving along.

I am just praying that DB by some act of God is less busy when my block returns lol

Maybe I will have to bribe Jim and Scheides with beer and cookies or something to help me go up there and work on it...which probably can't happen anyway as I am sure it would be an insurance thing for working in DB haha.

**mlomker** · 06-06-2011

They had posted an ad on Facebook to hire a couple people. Not sure if they have yet but maybe things will improve a bit.

**cmspaz** · 06-06-2011

I installed my injectors inside the shop, shouldn't be a huge deal.

Yeah.. Injector installs are a bit different then engine installs. Especially as far as an insurance liability goes. The only people who are going to let you know if it's okay would obviously be Shane or Danny.

Bingo...I am guessing insurance wouldn't happen. I am not sure how much time it takes to assemble a long block. I'd assume a few days to assemble and drop in and maybe another day to wrap up the little shit. Unless you are beast then you could prolly knock most out in 2 days working long ass days.

No idea though, it all depends on what problems you hit I think.

I'll stick to praying they can squeeze in the motor re-installation in a few days when the motor gets back.../praying.

**Murlo26** · 06-07-2011

I already found a buyer for my AMS downpipe as I have been wanting to switch out to an o2 dump one....want the most out of the setup etc etc and my car is already stupid loud anyway.

Regardless, I was talking to Chris Carey a bit today in emails and found this..

http://www.maperformance.com/product...oductid=101234

The thought is to run this with an external gate in conjunction with my internal gate. MAP did this on their 722whp stock frame evo 8 shop car and it worked great. It allows you to easily implement a nice external gate without sacrificing twin scroll. Just going to an external gate without keeping the internal one gets rid of twinscroll. The only other way to keep it is to use two external gates on your manifold which is like a 2k manifold setup...no thanks.

So I was planning to get MAP's downpipe anyway so I figured for a few hundred bucks I won't have to worry about my wastegate opening up as I believe it was before.

Everyone's thoughts? I know more boost != more power but for the sake of discussion ignore that and assume it will

I see no downsides other than possibly spending 200-300 extra dollars on something that may not work...otherwise it won't hurt anything else I don't think. It's the best of both worlds as Chris said and I believe its the same setup AWD motorsports uses to hold boost so well on their stock frame cars.

**scheides** · 06-07-2011

Nice! that would be pretty slick!

**Murlo26** · 06-07-2011

I think so, I think its worth a try for sure. If I could get the black to hold boost like it does on the evo 8/9's that could be worth quite a bit of power. I mean it is the same wheels and everything just a shittier housing I think so who knows.

**Shane@DBPerformance** · 06-08-2011

We run them that same way on some originally internally gated turbo cars. There is a possible downside and it is turbo failure. If your turbo fails and the manufacturer figures out you were doing that, then they might not warranty it. The internal gate is somewhat is a safety feature to help save your turbo, when the exhaust back pressures get way too high, it blows the internal gate open and slows the turbo back down some(boost drops). A lot of people try to push these bolt-on turbos farther than they were designed to make for boost and power for more than a few 1/4 mile passes and that's when you can see failures.

**Murlo26** · 06-08-2011

I am a 1/4 mile kinda guy, not endurance so hopefully I'd be ok.

Lets pretend the turbo in question was ball bearing, would the risk be reduced greatly?

I don't plan to push the car quite as hard as before, at least not right away until I make sure everything is perfectly working but the X turbos seem to really dump boost up top compared to their 8/9 counterparts.

edit: what kind of spring pressure would I need on the external gate? I am looking at the compgate ones that MAP designed their downpipe for and they go up to 26psi...I am guessing at least 20psi but maybe external gates don't need that high of a spring?

I'll remember you saying that next time something blows up and you're bummed about it.

Did you buy your car to go down the track a few times or to have some fun on the road?
