I do not want to double post but I had to start this in the Noob section. I have a few more questions so I thought I would start a new thread here. My origanal thread can be found here http://forums.nasioc.com/forums/show....php?t=1706494

There are tons of cosmetic stuff to do also.

So my first two questions are what belt to run after removing the power steering and will a stock fuel pump pull up and out of a 12" fuel cell? Thanks

To answer your fuel pump question, are you running stock injectors? If so, the stock one should be fine for this. Personally I would get a Walbro 255lph fuel pump so you don't have to deal with it later if you decide to run bigger injectors and a larger turbo. They're roughly $100 and most of the people on here use them for their projects, including myself.

This is a really cool build, keep us updated . I've always wanted to put an EJ20 in a 914.

I do not have a stock fuel pump. I will have to buy a pump, but I want to be sure the walbro will still work when pulling the fuel up and out. Where is the stock pick up and is there a transfer pump? Thanks

As long as you don't need to reset your ring and pinion set up it's doable for most home mechanics. There's a couple of specialized factory tools that are helpful to have, but if you check on the Pelican Parts forum you can find the work arounds that guys have come up with.

Feel free to contact me if you get into and need some guidance. Advice is always fee. Also, not only could we rebuild it for you if you decide it's more than you want to tackle, but let me know what service parts it needs. Or, if you want to regear it. While rebuilding and service parts are something we do, our focus and specialty is the special ratios gears, ring and pinions and LSD's.

I'm doing an ej25t - 05' Sti to Porsche 901 5spd that was just fully rebuilt with a longer 5th. this is all going to be hung in a bug chassis with a racecage. I was wondering, how low is your engine (ground to bot. Of oilpan) ? What ecu/wiring solution are you using?

And which adapter / clutch / flywheel are you using?
Nice build so far. Can't wait to see more.

Wow Matt way to talk dirty to a guy. I have been looking around at a few rebuild threads and it looks doable, but a hell of a lot of work. And I guess the LSD install will require the ring and pinion to be set up again? What type of LSD do you recommend? I come from FWD cars so I know very little about the clutch types or brands. I am hoping that the gearing is better with an EJ20 than a V8. I also have a friends 81 SC here that could use a rebuild....

are you going to reverse your intake manifold? It would make more sense to do it that way

Flip the alternator over in the ps pump spot before you buy the belt and turn the intake around and the turbo plumbing is a lot easier. I would still use at least the wrx ic though or you will be limited to about 5 lbs of boost because of the turbo heat.

Charliew Any links with how to do this? I looked at it and want to keep my AC,but I may change my mind. Thanks

I need help with the fuel system. The tank I have is set up to pull fuel from the top and return from the top. It is not set up for an in tank pump. The pick up is just a long tube and I know that high pressure EFI pumps are not built to lift/pull. So I am very worried about fuel starvation on the track. I am also worried about wiring an in tank pump. I am thinking about welding a bung or two into the bottom of the tank and using an external pump but I need a way to control the fuel slosh. I have about 6" of fuel foam to put in the bottom of the tank. Please check out the pictures.
And this is out of my budget surge http://http://www.hrpworld.com/index...action=product

awesome project! you'll get some downward glances from the porsche purists, but only love here!

how are you going to set up the intercooler plumbing? bet you could move the TB to the side and shorten your tract, or 90 down off the i/c, if you have it mounted the way i think you do.

I am having a problem with that now. Look at the arrows. The deck lid will not shut.

Ya my porsche friends love the car but the people with lots of money do not think much of it. And they like it even less when I am passing them. hehehe

i had a long discussion about doing a scooby swap into a porsche at an event at lime rock. the guy had a 90's rs america, and a new gt3. he was like "but why???" ... "well," i started off, "$$$, gas mileage, parts access, tuning, something different, power.."

he raised an eyebrow at that, and seemed a little flustered when i told him my 2.0 turbo would have no problem leaving his brand new 996 gt3 (in a straight line only, of course); and that a combination of the two might bring the best of both worlds to the table. the driving dynamics, experience, and feel of a porsche + reliable suby turbo power = win for less $.

he still didn't get it "something something, not a porsche, blah, blah, blah"

as far as the intercooler; it looks like if you flipped that end tank on the right you'd be able to clear it, and shorten your pipe a bit. or maybe leave the end tank as is, and just cut the aluminum pipe after it's been reduced, on a 45 or 60 degree angle toward the turbo... and weld on a new bit of pipe, with the new angle. got a good fabricator?

until i have my black/black 80's widebody 911/STi, i'll have to oogle at yours... which is great! keep it up man.

Cut the tank off in the middle and flip it over so that neck is on the other side and pointing in the other direction.

Just adding some more pictures for an update. I am having fun learning to TIG aluminum. There is still a ton of work to do but I am getting excited. Should I reverse the top coolant manifold?

I could be reading you wrong, but the way you are referring to your FP seems like you are going to mount it at the top of the tank... If you go with a walboro, find a way to mount it at the lowest point in the tank or you pump will be short lived. If you can, try to get your hands on a ls1(98-02) F-body sending unit, at the very least it will give you mounting ideas and you might be able to use the bucket that the pump sits in to prevent fuel starvation on hard turns/ acceleration. I'm sure other units are very similar but this is what I am familiar with. I like what you are doing here.

Are your exhaust pipes and turbo coated?? Are you having issues with belt longevity due to the heat radiating from the exhaust components??

Just curious. Cool project.
