2013 sport build

synolimit · 10-17-2013, 07:14 PM

Garage line sold me a "prototype" LTH that's identical to the eBay OBX header and 99% like a Fast Intentions LTH. The only difference really is the scavenging star in the FI collector.

I installed these headers after wrapping with DEI titanium wrap and the fitment was perfect. The bottom center nut is hard to get on with where the pipes are but let's face it, LTH's are a PITA to install!

First thing I noticed on start up was the rasp! It was horrible! So I welded in some Helmholtz resonators in the X pipe right where the X pipe bolts to the header. This amazingly cut about 90% of the rasp but also if I had to guess cut about 20 decibels of volume which I didn't like.

Next I cut off my mufflers and straight piped them. The muffler I had, had the pipes 90 degree bend into the mufflers then 90 degree bend again out to the tips. I didn't like that flow design plus I wanted my volume back. Now I might have one of the loudest exhausts but just sounds insanely mean with zero rasp and zero drone.

I still have no tune and running rich so power can be made from a tune! I'm just happy the car is rich and not lean. After 6000rpm the AFR drops to 11.9

. If we target 12.5 AFR maybe, that's going to be some nice added power there.

Peak power was 13hp and 17tq but mid range gained anywhere from 11-17hp and 18-19tq. 293hp 243tq.

Just ordered everything for a DIY diff cooler kit. The gtm is $1300! This is the same pump used and a good $900 saved

Where the gauge will be installed to watch diff temps and pump on off switch.

synolimit · 10-26-2013, 12:22 AM

Gauge installed.

nice build dude! I live near westlake, have to check out the car some day!

synolimit · 10-27-2013, 01:33 AM

New race weight, 3083 lbs fully fueled!! pretty happy about that. SCCA rules state you have to use a certain steel and size for a roll cage based off of vehicle weight without the driver and a empty gas tank. That means I'll be under 3000 lbs (2965 lbs) letting me use thinner/lighter steel. Still planning on getting 2 piece rotors all around and the JWT flywheel. Since that's only about 51.5 lbs I'm still looking for another 31.5 lbs to get under 3000 lbs fully fueled.

Sh0velMan · 10-28-2013, 11:52 AM

FYI, the 3000 lbs is with full fluids, with driver and safety gear, with the cage already in it.

If you're saying the car as it sits is @ ~3080 with driver and a full tank, i'm calling you a liar or your scales aren't calibrated worth a damn.

Funny, says without to me

Also good enough for these guys, good enough for me

Sh0velMan · 10-31-2013, 02:55 PM

****, you're right!

Dunno where I got it my head that it was otherwise. I read the NASA GCR (or whatever the hell it's called) probably a thousand times.

Guess my cage is a tad over-engineered then, but that's alright.

I wouldn't trust a damn thing that the guy at Forged says, but that's just me (they have an extremely bad reputation as of late).

GL with build!

Great detailed build. Really like the DIY hood vent.

Works too! The heat that pours out of it is insane.

synolimit · 10-31-2013, 07:22 PM

Changed the diff cooler one more time after I got everything and test fitted stuff. Ended up getting everything but the cooler from summit because every order I placed they then gave me a $20 off for the next purchase over $100. Hence the buying in small groups and not one big purchase haha.

DatsunFTW · 10-31-2013, 08:12 PM

Great build Sy! Subbed!
