Let The Build Begin...

[MyÜberFastGSX]

I know that I probably shouldn't make a thread about this. But I can't hold in the excitement. I've been spending money for the past few weeks, and parts just started to show up last night.

So tonight the build begins....

6 Bolt Block from a 91 Galant.
Stock 2g head
Weisco Forged Pistons
Brian Crower Connecting Rods
ARP Head Studs
SlowBoyRacing Exhaust Manifold ported
Tial 38mm Wastegate
Precision SCM-6152 Turbo
Whalboro 255 lph Fuel pump
Precision 780cc injectors
Aem High Flow Fuel Rail
Big Fuel Lines

We also rebuilt the tranny while it was out and put in a new ACT 2600.

We only have limited time to work on it each night. So I'm hoping to have it done in about a week and a half. I'll keep you all posted with pictures, and what not.

Wish Me Luck,
Darrel

hope everything goes as plan man.....wish best for ya! whats your goals for this car??

 

[Cs4g63]

Sounds like you will be having a lot of fun starting here pretty soon. Good luck.

 

[whiteflash]

Vancouver, Wa? me too...where do you live? not too many dsmer's around here....

 

[kmoore]

What ever happened with that guy that was trying to sell you a GSX body for 9k?

 

[MyÜberFastGSX]

Ok so first night off to an ok start. We did the balance shaft removal kit, but the balance shaft cover is broke. So I'll need to buy a new one.

To answer your questions:

Yea, I live in Vancouver, I actually live right by the mall. My number is (360)261-9921. Hit me up sometime if you want to get together.

I talked to my buddy and we worked out a fair price. I'm happy now, and so is he. I think it worked out well.

Day 2 tomorrow. Hope all goes well.

My goals:

We're hoping to get 400+whp on C16.

I'll be happy with 350whp on Pump gas for everyday driving.

Anybody think these goals are unrealistic?

 

[Talesin]

Don't forget to get an AFPR... that Walbro will be very likely to overrun the stock FPR, making tuning the car a pain in the ass.

Speaking of which, you're going to be running 780s, what kind of fuel management are you going with? DSMLink? A standalone (HALTECH/AEM)? MAF-T? Hard-burned EPROM?
SAFC will be craptastic for normal drivability, if you're thinking that route... IIRC that's hitting the limits of what they can compensate for, and they do it worse the closer they get to that limit, as the global deadtimes shift.. which can't be compensated for on that kind of piggyback.

 

[MyÜberFastGSX]

Well I'm about $4000 into this build. So I've stretched the limits of my budget.

So for now I'm going to be tuning with MAF-T. Were just gonna go on the safe side since I'll be running pump gas. We'll put boost right around 15lbs to avoid Knock from the low octance pump gas we have over here.

Once I'm able to save up some more money, which shouldn't take long, then I'll get DSMLink.
Unfortunately, I just can't afford it now.

Speaking of knock. Do you think it would be safe to run 15lbs of boost on pump gas with my setup?

 

[LordZed]

I run 93 octane @ 15 psi with no trouble. That's just with a stock ecu, 510cc's, and a big 16G. I would think you would be fine unless your talking 87 octane

 

[Talesin]

87'll kill the engine. :b

And I used to run ~16psi on a B16G, with CA 91 craptane and stock 450cc injectors. The bigger concern is how much more air you'll be flowing with that larger turbo... the B16 could push at that pressure, but it made for pretty hot intake charge. Yours will be cooler (read: more dense) requiring more fuel to get a good ratio, but making more power.
Get a good tune on it, and those injectors should be fine, so long as you're putting in 91 or above... and far as I know, nowhere in the US provides less than 91 as 'premium'.

MAFT should be fine for tuning, but you may run into low-end drivability problems, fair warning. Again, same as with an SAFC, the MAFT just will 'lie' to compensate for the larger injectors, but can't do anything about the deadtime. You can tune with the MAFT, but DSMLink will provide a much better result, once you can afford it.

 

[c4uldr0n]

any reason to use the stock 2G head?

 

[Talesin]

Some say it flows better than the 1G head, especially when ported to match a 1G intake manifold. Something about the angle of the intake runners as compared to the cylinder.
I don't really buy it, myself, but that's the argument.

He could also be doing it to cut down on costs, if he has a good 2G head just laying around.

 

[UofACATS]

What i'm thinking. Should work just fine.

 

[MyÜberFastGSX]

I actually had read about the 2g head flowing better, with the intake angles on the 1g intake. But I didn't look to far into it. I just used the 2g head ### I had a perfectly fine one laying around. Lol.

I'll be running 92 octane fuel with octane booster in each tank (I just bought 30 bottles from my friend that works at a local parts store.) With the octane booster my fuel should be over 94 octane. So I figure I should be able to run 15 lbs around town on that. But we'll find out come dyno day.

I have to take the whole weekend off the build, because the shop we're doing the work at is closed on the weekends. So I'll be biting my nails this weekend waiting for monday.

 

[Talesin]

Should be fine on just the 92, with those injectors. Honest.

Additionally, you may want to look into buying some Xylene at a tool store... local handyman joints should have it in big five or ten gallon jerrycans. Those 'octane boosters' are mostly just xylene watered down, so people can see a bottle, rather than a dinky little capful.

Do a search for xylene... much cheaper way to bump your knock resistance.

While you're doing the build, why not swap to a 1G intake manifold/TB, and just port the 2G intake runners for smooth flow? The engine will breathe a lot easier that way.
