How many here have blown their motors with your turbo?
i was wondering how many of you here have blown your motor with your turbo. what motor did you run it on? what turbo was it? how did it blow? if you could do it again would you try and fix the problems with the turbo on the motor or would you not turbo it at all? i am asking because i am debating about whether or not to turbo my jdm gsr because i am using it for my daily driver and i am worried about the reliability. i also want to here if how long you guys have been running turbo currently or before the motor blew.
I did blow my motor, but I had a rod knocking. It's a JG Fully Built H22 (not recommended to get a block fully built from them). They had the bearing clearances too tight, which starved the crank of oil and thus burned up the bearings. Trashed Crank, Rods, Pistons, Turbo (garrett T3/T4). I love JG Products, but I'll have my shop put it together next time instead of buying it built from them. $5000.00, still haven't got my car back, and it's been 2 months.
its all about self control.....
i wouldn't worry about blowing your motor on your gsr.
what kinda boost were you wanting to run, or how much more power were you looking for?
you can blow your motor just as easy as if it were turbocharged, it all depends how much you beat on it and how well it was tuned. but if you run say 6-7psi and dont get too boost happy you should be fine and your motor will have a long life.
i was looking to run about 1-8psi daily and then maybe turn it up to 10 when i try and run someone. but i have been reading some threads and they seem to think that i will get better power gains on a revhard or a drag but they also say that if i want a very safe reliable one then i should go with Greddy. i want to be able to run about low 13's in the quarter mile. i was originally thinking of going with Greddy but i just don't want to blow my motor.
Had a friend who blew the turbo piping off of the intake manifold and fucked up the turbine some how. he was running about 13lbs too so that could have been a factor. I'm currently debating also whether I should turbo my SOHC, or swap and then turbo later on.
it depends on what you want. going turbo is fun and can be a challenge at times. so many factors rest on reliablity but if you boost calm (5-9 psi) with stock internals you'll be fine. and not to mention it's best to run with an intercooler for that reliability and boost. people blow their engines cause of a lack of maintenance and not using proper engine management equipment and techniques as simple as a boost gauge, etc. you'd be surprised how many people don't know what they're boosting at.
turboing a sohc is fun and you learn alot, but if you're set on hitting near the 13's without too much effort, then a swap may be the best choice. it depends on what you want to spend and your speed goals. do it right the first time. good luck
Just for the record, I want to state the a nicely built SOHC turbo can run 12's. Costing nearly the same as a swap; and once having the swap not too many people can turbo right away due to lack of funds. Least I know I can't. So like themi6group said, it all depends what you're aiming for. In my opinion turbocharging and building the SOHC is a good choice, but the swap would be better. Granted if you have the $ for the swap and turbo go for it.
I know some guys in my neighborhood, who own this shop, and they have many 12sec civics. One of the owners has a SOHC turbo civic running 12.3 and thats a daily driven car. His friend 12.5 with a SI turbocharged as well. BUT: Sohc running 13lbs, and Dohc running 9lbs. Debate and explore your options. High boost or low boost. Boosting high would of course require you to build the bottom end a little. That's my $.02

Sometimes I wonder if people read the thread B4 they post...

your engine will not be able to handle 8 psi... first off USDM compression is 10.x:1 isn't the JDM compression 11.x:1?? correct me if im wrong please...
If i were you i wouldn't run anymore thne 4 psi on that high of compression... IF that. Get 9.2:1 pistons and rods then you can boost about 8 psi daily and 12 on track.
Well I think Dr. Drew is right to an extent. The Thread was about, "If any of us have blown our motors with turbos." However, he wanted to know because he was debating on wheter to turbo his car and wanted basically to see the downsides and upsides of a daily driven turbocharged car. We were just saying which ones we perfer over the other and why and what are plans for ourselves were. SO BASICALLY You were both right. But then again what do I know.
I blew my motor about 6 months ago. I have a B18C1 and I was running a Drag Gen 3 kit. I believe a JDM B18C1 has a cr of 10.2 to 1, not 11 to 1. Even if the cr was 11 to 1 turbocharging is still possible with lots of good tunning.

I was a mislead by your statemant. I thought you were refering to the original post. I stand corrected.

i have blown two motorz a b16a and a b18c1 i was pisswed off about the gsr , both i was boosting just 7 psi with the same set up i am running in my b20 and now it is running perfectly fine all i did different was get 310cc injectors,a EGT gadge, and get it tuned..... if you want a set up to last i believe tunning is the key to making it last ..... good luck though
