If you had an evo with 104.5k miles, already making about 350whp on turbo, trans, engine. Compression of 150-155 across. Would you do a new turbo setup? I want to rebuild my engine eventually but i feel like its i good health to be able to push it a little more, just looking for opinions. Goals are roughly 400~. I dont want to push the 500whp until i do a rebuild. This is on 93 pump.

 

i have an 8 with stock turbo.113 K miles.pushing 360whp on E 85.compression is a little less than yours.but i recently purchased 9 turbo to achieve around 400.and i will do the turbo regardless of my high millage

 

Go for it. Worst case scenario the car will burst into flames and you'll just have to get another one.

 

LOL. Thats not funny.

Do it but be prepared mentally and financially to deal with a rebuild if you should need it. As long as the motor is healthy you should be fine but there is nothing wrong with being prepared.

 

+1
More power = more stress on motor. But if the motor has been maitained well, it should hold the extra stress.

Good luck and have fun.

 

What turbo and how do you plan to control torque? If you keep the torque reasonable and have a turbo that has the breath to get you to your goals then I see nothing wrong with that.

I have 140K on the stock block and will be getting a bigger turbo within a year going for 500+ HP with 425-450 TQ.

 

Put the money towards a new short block instead and enjoy it the way it is, in the meantime.

 

Does 150-155 across sound good for an engine with gsc s2 cams(ive heard that changes it).

 

I wish I have these numbers.mine from 120 to 145

 

I'll prob just run this setup for a bit, it fun on the street. Then upgrade to a buschur 2.3

 

Is that 425-450 torque you mentioned on a stock block? I have heard a lot of positive reviews on your tuning, are you saying that amount of torque is ok with a high mileage stock block? I always here how my engine is ticking time bomb with my torque. Sorry about going off topic op.

 

I take it those are your numbers in your sig. I'd have to see your dyno chart and logs to confirm. Also using a 3 port really helps the safety of the tune. There are many variables. Overall, I'd say enjoy it. If everything is up to standard, my standard , then it will be safe.

Back on topic. I like what people are saying here. I agree, save up for a build. That totally contradicts what I posted earlier. However, I think you should do both.

If you are going to do a build, aren't you going to do a new turbo set up? Then you'd have to save for both anyway. Why not use the new turbo set up on a healthy engine with a safe tune for awhile and save up for a engine rebuild? Better yet, get a spare 2.0L or 2.4L and start building it or gather parts for it.

Either way you're taking a risk, OP included in his current HP/TQ levels. We just have to be big boys about it and know that modding our cars can leave us Evo-less for awhile. To lower the risk, not eliminate it, you need to get involved with your tuner and with your mechanic and know what's going on and discuss the risk. Risk management is what it's really all about. Even at stock levels the engine is going to go at some point.

 

Your right. Im gonna save to do an fp black on an new buschur 2.3rpm short block. Im still grabbing parts for you to do my SD tune!

 

Worst thing that could happen is that it spits a rod out of it lol.

 

That just gives me a reason to start a new build lol. I was just wondering how good our blocks are with pushing limits. Im also scared to start a new build cause i hear pf alot of failures.
