I'm looking at getting a civic with a built GSR and 50 trim turbo. The guy is claiming it made 360hp and 330ft lbs at 12 PSI, but doesn't have the dyno sheet to prove it. I'm not a pro at these engines, but I do know that's a high torque number for these engines.

I know that there's a ton of unknown variables as far as build, dyno, fuel, tuning, etc., but I'd like to know if these numbers are at least in the realm of possibility for the few specs I do know. He claims its a daily driver, but I just want to know if it's something I should look into, or if he's lying. Any info you can provide would be helpful.

 

Have him meet you at a dyno of your choice, pay for the dyno run and determine approximate power, buy car if you want it and the claimed power level isn't an outright lie.

Just remember that different dynos will produce different numbers, and even the same dyno on different days / weather, but check to make certain it is at least close.

"50 trim turbo" doesn't tell much. Find the exact turbo, and check the forced induction forum for others people using that turbo and what their results were.

 

Yeah I know there's a lot of grey area there. His ad didn't have too many details. Thanks for the help.

 

330 Pounds of Torque? No Dyno Sheet? I'm calling bs.

A 50 Trim sounds like an Ebay Turbo, and doesn't sound like a large number, which makes 360 WHP on 12 Pounds a stretch, but very well possible with a good tune. 330 Pounds of Torque, I really don't see that, however, maybe he has put in a larger crank for the Torque.

Also, most people keep there dyno sheet as a pride and joy of what they built, and if they don't have it, its because they were disappointed with the number so if he tells you it makes 500 WHP, would you know the difference?

 

there is NO way he is making those torque numbers

 

330 is a ton of torque! No way!

 

yeah a 50 trim can handle the power but the number juts dont match up
ask what the tubo specs are and his whole setup

 

It's a bit far fetched with they high of tq numbers but there been a boosted d16y5 that made more tq then horse power lol

Just say it COULD have that high of tq .. but ... i'd have to see it

if memory served me right was like 200whp and 230wtq or something like that

 

that torque number isn't possible even if it was a 2.0

 

the 50 trim is a smaller turbo, I could see it making good torque numbers, but I dont know if it would make THAT high of torque numbers.

Whats all done to the GSR? Tuned on pump? E85?

My buddy made awesome torque in his D16 Turbo civic with a zex cam and E85. with a 57 trim he made 402/346 @ 25lbs though haha.

 

na it doesnt make any sense, if it was 360 and 330, that means it would only be revving to like 6500, impossible.

maybe he meants 230whtq?

 

The lack of dyno sheet, specific build info, and the simple fact i don't like the idea of purchasing someone else's "project" would make me stay away from the car. If the guy had a legit car he would be pimping it harder. He would be going out of his way to givie you tons of info about his build. I'm betting there is something wrong with the car which is also why i always stay away from stuff that has already been tweaked

 

I would be pretty skeptical of those torque numbers. It isn't unreasonable to think it made 360/230, but i wouldnt think 330wtq is a little far fetched...

 

Bullshit. The HP MAYBE with a large turbo on a dynapack. But Torque, no way. Not out of a B18c.

 

No way he made it. I wouldnt be surprised if those numbers came off the butt dyno.

 

my old setup i ran 12-13psi i was making 330 with my lsvtec(82mm) w gt35r and around 240 tq i think
18 psi was 460s and 330 tq

i call be also

 

BS as well!
The TQ numbers are very high and normally you'd see those from a built Ls/vtec or GSR making around 450 - 500hp or so......

My built, stock sleeved Ls/vtec made 410/302 if that gives you any reference.

 

Those are like 2.5 Litre Subaru numbers for a GT3076R (or about 52-55lbs/min) turbo. No honda will do that.

 

On a smaller turbo ya. My LSt makes 360/340 on a dyno jet. But on a GSR and a 50 trim, no

 

only way that could happen is if the turbo spiked way up and fell off to 12lbs by redline

 

 

Just some insight. A dyno measures Torque and multiplies by 1.4 to get horsepower. A car that makes 330ft/lbs would make around 450hp. I know this is an older thread but thought I would throw in my 2 cents

 

I really dont think so, but ok! haha

 

i second that. how do you explain motors making more torque than horsepower if this were to be true?
