Most HP safely out of stock 7bolt

[jp91gsturbo]

The 14b if tuned right can make enough power for what you want. I personally run a 14b with a small 16g comp wheel. Dont have any actual numbers but I know it spools faster than a evo3 16g and should make atleast 300. I'd be pissed if I dyno this thing and it doesnt. It will leave some 5o stangs and ws6's pretty easy. Throw some 750 injectors behind it with a 255 wally, aeromotive fpr, and dsmlink and a blowthrough or vpc setup and you'll be thrilled.

The weak link turned out to be the rods.

Thats them cute little 7bolt rods for you

So, you have a small 16G turbo then, right?

 

[dsm-onster]

With a 6cm^2 turbine housing.

With your listed set-up, and assuming your engine is in good running condition and it's tuned correctly, a stock 7-bolt will laugh at the numbers you'll be able to make and take it just fine. But you probably wont be able to make much more than 230whp. But for what it's worth, I ran the time's in my profile on a stock 7-bolt with 125k miles on straight pump gas.

How are you figuring only 230 whp on a 7bolt when some guys that do slight mods and good tunes are in the mid to high 300 range?

What was the fix for yours if you don't mind me asking good sir?

The fix was accidentally driving the car into a couple k-rails out in front of Soldier Field after HIN.....

Like I said, I had a 6 bolt in a 2G, so the fix would have been a 1G CAS, which is irrelevant in your case. Random misfire codes can be from a number of things unfortunately.

Taken from an old post in 2005 -

A "random misfire code" (P0300) is even harder to diagnose because there can be numerous causes. A random misfire usually means the air/fuel mixture is running lean. But the cause might be anything from a hard-to-find vacuum leak to dirty injectors, low fuel pressure, a weak ignition coil, bad plug wires or compression problems."

Sorry I can't be of more help man.

You were actually pretty helpful, but I put new wires in, haven't had that code since but I just found out the wastegate solenoid was missin...

I was running 27 psi on my old 50-trim and flowing 47 lbs/min, all on the original head gasket and head bolts. The weak link turned out to be the rods. With quite a bit more boost, they all hooked and the head never lifted or pushed a drop of coolant. Right around 50 lbs/min is as far as I'd feel comfortable pushing the factory rods and head bolts.

As far as advertising flow and the associated turbo what else happened during this event were both of these rods from the same engine? Did you detonate? Are those stock rod bolts.

Let's be less vague whats going on here it's like you're holding up a shark you caught at sea.

I see some deep scratches and a very wet looking piston.

 

[dsm-onster]

deep scratching on the piston can occur when rods bend and send pistons against the walls. You see them at the skirt opposite the direction of the bend. detonation typicaly occurs on the exhast side of the pistons sending the opposite skirt against the wall. Or always in my case.

Regardless of your lack of trust of Paul, you've never seen a 7bolt take more abuse than a 6bolt. But the other way around by 80ish horsepower or so. There's no benefit for him to lie or intentionally fail to insert pertinent information, unless he has a hugh stash of 6bolt rods hidden somewhere. He not diagnosing the true cause of his engine failure is even less likely.

:sighs: the ''trust'' discussion I don't have time for that talk.

I asked for some more info frankly.

 

[GsXdSmKingGsX]

a 14b, injector, fpr, and a 255 pump And you could see 300. That is of couse only gonna be possible with something really good to tune with (dsmlink) and fix the boost leak

He said he didnt want to deal with J-pipes dude

 

[dsm-onster]

:sighs: the ''trust'' discussion I don't have time for that talk.

You saw in the picture the grinding of the pistons on the walls in the other direction. So it wasn't detonation. You've seen detonation damage within a 4g63 right?

As for the pistons being wet, suggestion would only be hydro lock. Then you had better know who you're talking too. If you don't have time for the talk then don't ask the questions. He said what happened. don't waste your time with any other remote possibility other than the rods bent because they arn't strong enough; the markings you've noticed prove no det. Guy's not an idiot. . . You see that right ":sighs: and overdramatic enterweb moan speak"

I CLEARLY said I don't have time to put up with some ''insert first name here trust him''. It's simple if the picture posted the question is asked you're not the owner of this picture then you don't have a clear anwser unless you are part of it. Also the '' had better know who I'm talking to?'' I don't care.

 

[dsm-onster]

You know it's not detonation. The markings clearly show that. What else is it? He gave all the details. 7bolt rods, a picture of the markings and results, no cracked ringland gaps helps confirm too. There's nothing more to know. You know that. You can decipher what happened with the material pictured just like every one else, right? You see all he saw. It is what it is.

 

[99gst_racer]

were both of these rods from the same engine?

Yes, I bent all 4 to some degree.

Did you detonate?

I overboosted badly (zero wastegate control), and this was the first and only time it ever happened. I wasn't datalogging at the time though, so I don't have actual data to show what happened. But I was tuned for around 25-30 psi, so with it running 40+ psi, I assumed that I had some preignition issues at that point. And that level of cylinder pressure coupled with some preignition helped shed some light on my weakest link.

Are those stock rod bolts.

Yup.

Let's be less vague whats going on here it's like you're holding up a shark you caught at sea.

I'm not hiding anything here, just sharing my previous weakest link. I overboosted. The stock head bolts and factory head gasket that everyone is always so worried about, held up just fine. The factory rods couldn't handle it. The pistons, spark plugs, and factory rod bearings all looked fine upon disassembly. This engine only had 75K original miles on it and was pulling 185 across the board before this happened. And it's worth noting that it still ran fine after bending the rods. I drove all the way home on them.

I see some deep scratches and a very wet looking piston.

The rods bent enough for one of them to make contact with the lowest most point of the cylinder wall. And when the tang of the piston was at it's lowest point in the bore, it was being scratched and scared up from the damage to the wall. The pistons looked wet from sitting upside down on the engine stand.

UPDATE
Now wondering if my BOV isn't adjusted properly OR my FPR or FPS is jacked, It builds up to 5 lbs and either bogs down and starts "2 stepping" is that still boost leak or would that constitute as a fuel issue? The last fix was a fuel press. solenoid and that as well as the fuel press. regulator were both used, I'm wondering if one of them may have crapped out on me again...

 

[TheMitsuGS-T]

you'll be lucky to make over 200 whp with t25

thats funny ### when they come off the line at the factory with the t25 they make 210 hp...

 

[sax_man]

thats funny ### when they come off the line at the factory with the t25 they make 210 hp...

They make 210 at the crank. He's talking about power to the wheels.

 

[donniekak]

At the crank, not the wheels.

 

[jjrock5]

[MidShipCivic]

You can make a t25 put down 200whp it's preschool to do so.

 

[dsm-onster]

Post links to the proof or to the varification by you yourself plesase. No disputing the possibility, but appealing for more than simply trusting your word for it. You're not Paul

I will say that the t25 shows about 27lb/min on the compressor map. Which is why I say it is possible.

 

[project1g]

Sorry I havent been posting much lately I started a new part time job... Anyway I somewhat fixed some problems on the car.. Now my little T25 is pushin' 8.5 lbs which someone told me I might have an Automatic trans. wastegate.. Or another boost leak. My 2 step problem was about 6 destroyed couplers and some a** backward vaccuum lines.. Problem solved Ordered a Fuelab 515 AFPR (still not on due to some trans issues) Boost controller isn't in yet.. aaaaaaaandddddd now I'm wondering about this set up idea.
Because my ECU is metal. no *E* anywhere on it I assume its non eeprom
EVO 8 ECU (or eeprom)
510 EVO III Injectors
The AFPR
Boost controller
New FP manifold
BC 264/272 or 264/264 cams
Some sort of datalogger
and best of all a 20G turbo and new custom Intercooler to go with it.
With this setup and DSM v3 Lite should I not be able to make more than 300WHP and get into the 12s?
Safely over all.
The guy who built the motor told me that I'm voiding warranty with this BUT it should more than likely with a good tune handle over 450whp in his terms ( Just like any other 7 bolt bottom end ) which I don't know if thats praise or not good to hear But thats my set up that I'm going to hopefully save up for once I know that hopefully it'll get me a good bit of numbers.
What do you guys think?
This all came from a buddy of mines Colt thats in the 10s with 288/288 cams same turbo set up but with slightly (h-beam rods and 9.0:1 cp pistons) set up on I believe he said 18 or 22 lbs of boost I'm not sure ...

I'm sure if he said he rubbed some sweat off his balls rubbed it on a T25 and made 500whp with that you'd believe it.

205.2 WHP/ 196 TQ @ 10-11psi

D16Z6: Stock
DSM T25
STD Manifold Cast iron SOHC manifold nothing special
DSM 450's
DSM BOV
Custom dual core IC
2.5" straight exhaust
Uberdata
all on a Motor with 260,000km's on it. (about 160,000 Miles).





This is a smaller Honda 1.6 SOHC engine, The foundation for 90's civic's and integras is 200whp = 13 second runs. All Motor or Turbo. I believe this was a DX Coupe with is 2,231lbs factory.

Everyone knows the ball sweat trick only works on ball bearing turbos.

 

[project1g]

Maybe if the sweat came off the balls of a compound turbo owner... Not pointing any fingers But seriously that set up above should get me well over 300 correct?
