50 Trim Stock motor

[HyperGSX]

Who is still running a 50 trim on their stock 6/7 bolt? How many miles have you put on this setup?

I was running a BB 50 trim on my stock 6 bolt for about 20k. I finally fried the ring in cylinder 1. But my compression was only 136 across the board to begin with well before the 50 went on. It was only a matter of time before i broke something in there. I did however make 363 awhp and 323 awtq with the 50 trim on that set up.

The previous owner of my current car had a FP green on the stock 7 bolt for 25k with no issue. The green finally died which is why it's no longer there.

I ran about 6-punishing-thousand miles on my 7 bolt before it gave out. I currently now have 2k miles on my built 6 bolt running 22+psi. This is on a pte 5031rle (ball bearing)

CanadianTSi is still on his stock 7 bolt and has gone 11.8@120+ on a 50 trim + SAFC.

 

[VTEC_THIS]

I got 113k miles on my stock 7 bolt, and just put my sb g50 turbo on about 3k miles ago. I'm running 23psi on 93octane.

^^ I'll let you know how this holds up...

Yep I ran a 50 trim on my stock 7bolt for 2 years and have since moved on to a GT3561.

I used to daily drive my stock 6 bolt with a bolt up 50 trim and supporters running 20 psi. Loved that turbo, spooled nice and quick and still pulled hard. Upgraded to a 60 trim and never looked back though.

Had my BB 50 trim for a year,but put cams and manifold and goodbye 7 bolt. Lasted 2 days.

I'm sure it wasn't the 7bolt fault. I've been trapping 125-130mph for 3 years on my stock 7bolt with no problems. It is all in the tune.

Nothing Special just a bolt-on Internal gate PTE GT3561, been running it all year.

Ran a 12.2 at 123 with driving issues and last time out at the track I ran a 12.1 at 113 with Horsepower issues, I have a feeling the stock 7bolt is down on compression but I haven't tested it yet, also the TOB took a dump so i can't even drive the car.

I May just have to do a Twin disc and Stroker over the winter...

50 trim stock 7 bolt here, 8k miles. 20-21lbs on pump.

I installed my PTE5031RE BB this past March and my 7 bolt gave up in September. However, it walked on me and I also think overheating might have had something to do with that, not the 50 trim. I have a JDM motor now and now my turbo is gone for warrenty repair. Internally, I also have ARP headstuds and BC 272/272 cams.

The turbo is great as I ran 22psi. During the winter, I am planning on installing a water/meth injection kit and also shopping for some meaty slicks to get the car to stick. I have FWD (sucks).

Wow an internal gated 3561 ran 123 on pump? how much boost were you running?

 

[CanadianTSi]

It was actually a mix of 110 and 94, I was at 26psi and maybe 15 degree's of timing. I was picking up 1-1.5mph for every degree of timing so the car had easy 125's at 26psi. Also boost holds rock solid down to the tenth of a Psi.

Sorry to dig up an old thread but I am thinking about going a 50 trim route over the EVO 3 16g. My question is when all you guys refer to your engine being "stock" do you mean it has not been built or modified in any way? Basically, are these engines stock everything including head gasket and studs? Thanks for any replies out there!!

I had a completely stock 6 bolt, stock heads studs, all that stuff. I have a scm 5031e and a fmic, fuel system, full exhuast etc. You have to have teh supporters obviously to make it work.

 

[silver bullit]

Completely stock 6 bolt with 50 trim, ran 25 psi for 7k on an the fresh 6 bolt rebuild with stock parts, ran great till i sold it.

 

[c4uldr0n]

I have no problems after 3k miles with my stock engine 1G 7bolt and my SBR G50 @ 20psi. The only things that I've "internally" updated are 3G lifters and 264/272 cams, other than that bone stock and 120k miles w/ 150psi compression across the board!

[drewvr4]

ive had my bullseye 50 trim on for about 5000 miles, the turbo has blown up twice and my motor is about the quiest 4g around, 150 psi across the board.


fyi Bullseye Turbos are shit

 

[HighPSI TSi Guy]

6 bolt is good to 600+ whp.. No limit really found yet
7 bolt is good to 500+ whp.. have yet to push the limits

I'm jealous

Let me clear this up before it goes any further. Although the guys on this thread have taken their stock 6/7 bolts to the max (or even just daily driving) with a 50 trim, does not mean yours will be able to take the same beating. Driving habits, driver ability, maintenance, compression readings (health of engine), tune, etc. all are equally important to the longevity of an engine. Hell, I bet if I could find a nice 150k 6 bolt, slapping a GT35R on it with a great tune @ 20psi, she'll hold up. The point I'm trying to make is don't base your goals on what others have done (although it's always insightful). Make sure your engine and your car is up to the task of a larger turbo and this way you can pretty much dictate if it can handle it or not.

Also to answer your question, I have gone 110mph on a bone stock (down to the damned throttle body) 7 bolt with just an ACT2600 clutch on the worst SAFC1 tune you could imagine. It's possible, it's happened, but it's risky.

I had a Bullseye T04b 50-trim on my car for a summer. Probably 3K miles. It held up fine on my stock 7-bolt longblock. I then switched to a full T3 set-up including a new T04e 50-trim. Dyno'd out at 403 WHP on the stock block, head, cams, intake manifold and TB, head bolts, and original head gasket. I pushed this pretty hard for about 700 miles over the course of one year, and eventually installed cams, Magnus SMIM, and a 1G TB. I ended up overboosted (roughly 40+ psi) and bent the stock rods.

If tuned correctly, you can comfortably push the 50-trim pretty hard on a stock 4G63 without any repercussions. I definitely had fun with mine.

 

[b00stedtalon2]

As long as you have a good tune, you shouldn't have any problems. Ive had friends with much bigger turbo's on a stock 4g63, and they have held up fine.

6 bolt is good to 600+ whp.. No limit really found yet
7 bolt is good to 500+ whp.. have yet to push the limits

You'll have to post a dyno pull, as no 7-bolt has pushed that far and not broken very soon after!

I've pushed a 60-1 (10 lbs/min better flow potential than a 50-trim) to 52 lbs/min on a stock 6-bolt w/ a cam upgrade. The block can handle pretty much what even a cam upgrade can give it concering a 50trim, if you're running 6-bolt rods.

The 7-bolt is underrated. Most don't push it because they can upgrade the 6-bolt rods for cheap. But, 400+ whp is entirely respectable for a stock 4-cylinder block! No one has really gone much farther than 450 whp on a 7-bolt and have made a positive response about the results.
