Don't stick a power adder on it at this point. Sounds like you take good car of your car. I would suggest a compression test and a leak down test and that will give you a pretty good idea of the state of your engine. I'd drive it as is till you are ready to do a forged rebuild and put some real boost to it. Start gathering parts while you are waiting.

 

If you keep oil in it, no reason why it should not last for a real long time.

A S/C can be iffy at any age/milege but typically 60K is referenced as a benchmark. The real question is what are you going to do when something does happen to your DD?

 

When I get a chance I am going to grab an Aluminator short block, but I figured I'd have a little fun with it till then. I have a Vortech S-trim and wanted to use it before having to upgrade the engine. I figured 6lbs of boost wouldn't really be pushing it that hard and would make 2 lane passing a bit more of a hoot. Once the Aluminator goes in I'll bump it up to 10lbs of boost.

 

I put the blower on my 2V at 106K. There was no bad effect at all. That being said, on a 4V, you need to watch that you don't exceed the strength of the rods with a blower. If that happens you are SOL.

I am really not looking for anything more than 400RWHP, which from what I understand, is well within the limits of what this motor can handle. Does anyone think that this would suicide the engine?

 

Don't do it!

Get the new motor setup and sell this as a working motor and not a grenaded one! A lot of it comes down to having a proper tune but you're absolutely adding significant risk when you add the power adder on stock internals.

 

I bought my cobra with 98,xxx on her and immediately put the Vortech on. She now has 12x,xxx on her with no problems. Makes 380/361 a the rear. And its my daily. Drives great. Only problems Ive ever had from her were caused by me. If you have the money then go ahead and get a rebuild. if not then do what you want. As long as you use the stock pulley and have a good tune you should be ok. Thats if your current engine checks out good first.

 

Mine is similar, except probably not as pampered as yours. It has 160k and only uses a touch of oil between changes.

No knocks or pings, either, from the engine. Glad to hear I'm not the only one with a high mileage 4V that's doing well.

 

Blow it. You seem to take good care of your car. Most of the problems you hear about are from people who race their cobras. I would have the compression check done and if all is good...go for it!

 

I have 224-225kish miles on mine

original motor and trans with no rebuilds and still works purty
although she just recently picked up a head tick :/

but outside of that no problems!
engines last forever man!

 

hey man i put a vortech s trim on my stock 96 cobra engine with 143,000 on it np it made like 372hp and 345 tq. it was quick and ran great until the day i pulled it and sold it. to drop in an terminator setup. if yours runs good man put the blower on it and have fun with it.

 

im about to roll over on 70k so this is making me feel good. lots of life left..
