1. what was the cause for the motor to blow??
2. how many miles you put on the motor untill it blew?
3. what mods you had when the motor blew?
4. what head did you guys use?
5. what ecu was you guys useing?
6. did a shop did the ls/vtec b20/vtec or you did with a couple of friends?
7. did it have turbo??

if you guys had a chance to do another sawp what motor would you guys do? a motor for F/I. im plaing to do a gsr turbo.anyone have any opintions about this set up? but of course i will build the motor up 1st to handle the turbo. if not a gsr turbo what motor i shoild be looking to get? but rember F/I and ima fully built the motor 1st. thnaks

 

 

any help?????

 

 

anyone here blown an engine an wanna talk about it?

thought not...

t..

PS do a GSR turbo.

 

 

TTT... There has to be people on here that have blown their B20/Vtecs up

 

This is "ALL MOTOR B20B" car he will post later I will try to put up some pics later to
It was an LS/Vtec!


1. what was the cause for the motor to blow??
Mis shift

2. how many miles you put on the motor untill it blew?
1500

3. what mods you had when the motor blew?
rods,pistons,I/H/E,cluch fly wheel and more

4. what head did you guys use?
B16 (gen??)

5. what ecu was you guys useing?
Skunk2 red line 10,000 rpm (I am running it now and I love it)

6. did a shop did the ls/vtec b20/vtec or you did with a couple of friends?
Shop

7. did it have turbo??
NO

if you guys had a chance to do another sawp what motor would you guys do?
Well look at his user name

Hope this helps
Mike

 

Sorry there so big! I don't know how to resize?

the motor was a ls/vtec in a 92 teg
1) misshift and blew the ring lands
2)2000 miles
3)skunk 2 valvesprings, crower cams, type R pistons, skunk 2 im, + basic bolts on
4)b17 head (92 gs-r)
5)skunk 2 p28 ecu
6)me and the shop where I work at
7)no

I love ls/vtec and would always stick with it. I now have a ls/vtec in a del sol. But in the future, I would like to build a turbo gs-r.

 

When I blew it I was racing a mustang at the illegals. I had'em out the hole by like 2 cars, I shifted into 2nd and it jammed. I had problems w/ the tranny earlier that week, and had it looked at. I was told to take it easy but ignored it and u can see what happened. The new motor i have is the **** though!!!!

****, can you put a rev limiter to stop blowing the engine when mis shift?

 

I don't think a rev limiter will help if you misshift.

 

If you use a soft touvh rev limit or spark cut, a missed shift will not cause you to over rev the motor. You will just hit the spark cut and the motor will only rev to where you want it to rev. Using the stock fuel cut is problematic due to the fact that it starves the engine of fuel once the rev limit is hit...Obviously no fuel is one way to cause detonation and blow your motor.

 

uhh are ypup stoiopid?
why dont you get one of those spark cuts and shift into secdond at 100 mph and tell me what happens. if the motor is being PULLED to higher rpm by the wheels, nothing is going to stop it from overrevving.

 

Nope. But it should slow down REAL fast!

 

yeah - because of all the bits of metal clogging up the exhaust pipe!!!!!!!!!

#1 reason people blow up their motor. And it does not matter whether its an LS CRV or GSR:

MIS SHIFTING AT HIGH RPM.

Nothing can stop the motor, mechanically from going to whatever RPM it can get to...as in 12k+.

Referring to CRV/LS/VTEC's....possibly bad oil flow caused by alot of lower budget setups with LS oil pumps possibly.

Honestly, to be real, there is no downside to LS/VTEC at all if built right VS a GSR motor UNTIL you start revving it above 9k RPM. Then the LS/CRV crank will vibrate more due to the higher piston speed. And YES, it still vibrates when it has a girlde...

I wouldn't know....mis shifting is like 99.9% of all the blown motors. I mean, thats not just flat out negligence like no oil.

Thats my opinion. I have seen alot and we build probably more than anyone here.

Even when we push 480 WHP through a LS block with no girlde, at 8500 RPM it stays reliable for a period of time I cannot measure, because its still running...I should say "THEY" are still running.

Look to the answer: MIS SHIFING #1 reason people blow up....

'nuff said.

As far as misshifting goes, I now have a msd 6al in my car with rev limit and I can honestly say it save my butt at least 4 times already from misshifting....I would strongly recommend getting one!! I have my rev limit pills at 8600 so when i misshift, it won't go past 8600....Just want to say to Jeff and importbuilders..Great whp # from your b20vtec and lsvtec

 

LS and CRV motors were not built to be high revvers (even though i think the CRV has the same oil pump as the gsr/itr) but even still. They have a longer stroke for lower revving bottem end power. Yup mis shifts are a killer

 

I think when they mean mis-shift, they mean downshift into wrong gear eg, 5-2 or up shift 4 to 3.

so any kind of rev limit won't work in this case.

It happen when you sleepy...
