So basically long story short I was offered what I believe to be a killer deal on an FP Green. I know the owner of it and he said it has been reliable for him for the past 30k miles.

Anyways onto the main point of this thread. I have the following as my current mods and everything else is stock.

• Exedy Stage 1 clutch (the one that is a step above stock)
• Synapse LICP
• Greddy UICP
• Hallman MBC
• AEM Intake
• Prototype o2 dump downpipe (similar to the MAP o2 eliminator)
• Megan resonated testpipe
• Fujitsubo RM-01A

Before getting tuned I was looking at getting ARP headstuds, a GM 3-port (no resistor), and a Walbro fuel pump. Are the headstuds necessary or am I pretty safe with the stock headstuds that I have right now? I plan on getting tuned for around 25psi, maybe less so it will be more reliable. Will I see any gains from the MBC to the 3-port? Will I run out of fuel on 91 octane with the stock fuel pump? Basically I'm just trying to see what I can go without right now because I need to save money for Christmas and other expenses in the next two months.

Also will my clutch be able to hold the power that these mods will make? It has 34k miles on it with ~75 launches, probably a little more than that.

I think that's all of the questions that I could think of for now, thanks guys.

 

I don't necessarily think you'll see gains from MBC to 3port, but ability to control boost better may no be out of the question.

IMO getting a journal bearing FPgreen with 30k miles on it would NOT give me any confidence in how much life it actually has left...unless its almost free I wouldn't buy it.

 

30k on a taken care of turbo is fine.

You will see quicker spool from the EBC vs a MBC when its setup.

I would really spend the extra money on a fuel pump at the very least. Its 100 bucks and alot of safety. You will still run out of injector, but you will be able to push around 350whp on stockers I think.

 

Headstuds I think are not needed unless you are pulling the head off for service, stick with the MBC for ease of use. Get a fuel pump as soon as you can!

 

Cool thanks guys, anyone know if my clutch will be able to handle it?

 

Should be okay if you aren't launching

 

Nice! I can't wait! My car hasn't felt fast in such a long time lol.

 

I would definitely recommend head-studs if your running above 21 psi. You can run the 7-bolt dsm headstuds in the evo block, and they are actually a bit cheaper on most sites that haven't figured out they are the same part.

as far as the pump/injector argument.

I am not sure the evo's fuel pressure is the same. So take that into advisement when check out that chart.

 

I have been running 25 psi for the last 6 years in my evo, and have even ran 30psi a few times all on stock head studs.

 

how many miles does your car have?

I def. would recommend fuel pump and since your at it injectors to

 

Mine or his. Mine is at 78k.

 

This is one of the most mal-informed posts I have seen in a while... I was running 33 psi on stock block/head bolts... no issues

 

a 5-10PSI increase is nothing when you're talking about the pressures in the cylinders during combustion. The power you're making is a better indicator of what cylinder pressure will be like, and whether you need head studs. A black at 25PSI and a stock 8 turbo at 25PSI are completely different things, just saying a blanket amount of boost that's safe is silly.

 

Oh that is a good point. Didnt think of it that way. Im only at about 330-350whp right now. Gots to love crappy gas.

 

his.
sorry for the mix up lol
