Goes on insurance friday (tomorrow)

Martino · 05-25-2015, 01:35 PM

So this weekend was an odd one. Got the car all buttoned up and put on insurance etc.

Drove it around a small bit.

Than this happened.

There's a bunch of money down the drain. I hit the limiter sliding around a corner and my rockers decided to end their life. After doing some research I've found that the AEM rev limiter his hard when running a lot of boost and should be switched to have fuel cut come before ignition cut.

So basically I'm now back on stock cams and cam gears. I've also converted the rockers to be dual guides vs. guides and shims. That should stop them from kicking sideways and off their position.

I drove the car to work today for the first time which was tense as hell haha. Going to go for a tune adjustment after work to make sure everything is running properlly now with stock cams and less lobe rollover.

Who's idea was it to build an SR again? I miss stock SR days....

Almighty So · 05-25-2015, 02:27 PM

ah damn that's a real bummer

I've always been a KA guy myself but I hear a lot about cam/rocker issues on SR.
At least you're driving again already!

Yea, hopefully with changing the rev limiter setup and the dual guide rockers now I shouldn't run into that issue again.

There's no time to waste! Gridlife is next weekend and I'm trying to prep for it but keep running into these little problems. Hopefully they've settled now.

slow40sx · 05-25-2015, 05:41 PM

Well god damn, I'm glad it wasn't something way worse, I need to do the dual guide set up for sure, I dunno why the fuck it isn't just like that stock, glad it's all ok

Martino · 05-26-2015, 10:35 AM

So here's my latest dilemma.

Everything seesm to be running right and back together well.
I went for a tune-up last night and made a substantial amount of less power.

I made 340hp/330tq.

I've lost 120hp and 20ftlbs of torque. I've ruled out most of all things and have narrowed it down to no damage to the motor (compression tested and valves seem to be seating).

Could I really have lost all that power in the cams? Could stock cams with the combination of my setup really make that huge of a difference? Are they choking that badly and can't make much power?

Ultimately I'm still going to drive Gridlife and hope it doesn't blow up. At this point I'm far fed up and just want to have some fun. Shit if I get in a few laps and a party weekend I don't mind. I'm very fed up with this SR at this point.

Martino · 05-28-2015, 09:10 AM

Put some vinyl on for GridLife this weekend. It'll come off once the car is back and in street mode again.

Still have a couple supporting decals to put on. Will look good in some tandem team-mate runs.

PoorMans180SX · 05-28-2015, 06:30 PM

Woah, Gridlife is 45min from me. Might have to come out and see this thing/meet you.

I take it you did a leakdown? that'll tell you for sure if the valves are seating.

Ignition cut should be softer than a fuel cut, you should be able to set how often it cuts the actual spark.

Yooo! Come out dude. Pm me your number and come kick it. I won't have my data on so text is best.

the vinyl looks strange. chrome would be better than white, but i'm much more of a fan without any at all

It was definitely a last minute addition. I wasn't even going to do the vinyl to be honest as time was crunching down and it was my last priority.

I decided to go with just white as ordering in chrome wasn't going to arrive in time and it's not necessarily cheap so I chose to opt out.

I actually just want to go with a simple chrome piece on the bottom on the door. Just our team name in it's cursive logo - nice and simple.

for sure! that will look good

Martino · 06-02-2015, 08:30 AM

There's a ton of pictures popping up. I'll just end up dumping them here probably.

Event went great...kind of. I think the motor pooched itself on my last session.
Did a leakdown test last night and it seems like air is escaping past the piston. Either rings are gone or I melted a piston on cylinder 4.

Hopefully It's just that and not a spun bearing or anything. During the run everything seemed normal and numbers were optimal. I'm kind of leaning towards my oil pump failing..ugh.

VE head and you can bounce to the moon and back on the limiter. With the added benefit of making more power on less boost. Car looks good.

After fixing the limiter issue, hard to soft now, and making the rockers dual guides everything seems to be holding up top.

I did a leakdown test and all signs are showing block issues.
I'm going to start pulling the motor out this week and see what went wrong.

The end goal once I decide to stay SR or not would be to do a VVL setup or just put in a 1j. We'll see how the budget holds up. For now a stock bottom end will probably just go on.

Almighty So · 06-03-2015, 10:43 AM

Car looked good!
Was just about to ask how GL was.
Hope the motor isn't in too bad of shape.
Would be pretty gnarly with a 1j or VVL set up though!

...or maybe I'll just put a stock bottom end in, drive it for a year, sell it and buy an S15 lol.

Almighty So · 06-03-2015, 03:38 PM

could be down for that

JRex · 06-03-2015, 09:45 PM

Bummer man, sounds like the SR is cursed. You should just go 1j lol

Lol, maybe I just have bad luck haha

Pic dump:

Devo took these

Martino · 06-10-2015, 08:03 AM

So I took the motor completely apart the past couple days. Found shavings EVERYWHERE.

It's definitely a spun bearing. I flipped the motor over and found that cylinder two rod had a TON of play and you can tell it was heat cycled as it's a little diss-coloured.

Going to take it to my engine builder later tonight and see what I can salvage and have him measure everything to see what is usable and what I have to replace (aside from the bearings).

My SR plagues continue....
