Just an update: I was changing the plugs out today and figured I'd check compression while I was at it. The car has been turboed ~2 years now running between 11-12 psi on 91 octane pump, and I've put around 35K miles on the setup like that along with numerous street races and trips to the dragstrip. Compression was 160 all the way across, same as they were before we put the kit on it (we're at mile high altitude, in case those numbers seem low to you sea level people)......while I wouldn't suggest running 12 psi on pump at sea level, 10 on high octane pump should be just fine with a good tune.....

With good maintenence and no stupid abuse, I see no reason why a turbo stock motor prelude would have any shorter a lifetime than a totally stock prelude. I know people post all the time with questions like "will my prelude handle xxx psi as a daily driver on stock motor", well the answer is yes, 10-12 psi should be fine. Granted, this is with no stupid abuse (prolonged 5th gear boosting, racing in 110 degree weather, running shitty gas, lack of maintenence of fluids, etc) and assuming you're running a real kit with real engine management......

Just thought I'd post that up, because I know people are always curious about how stock motors hold up...

Thats is some good info, hopfully some people might take that to heart and not abuse the car they have. What kind of turbo kit are you using?

 

I'm going back to 9 psi soon. I <3 my boosted H22.

 

Awesome to hear Firedrake

I might consider boosting my stock motor if I had more

confidence in the tuners around here

 

Tune it yourself.

If only it were that easy........

About how much timing are you running on the top end, Firedrake?

 

What's your setup?

Wow awesome power!

There are some days where I have the urge to sell all my NA stuff and go turbo.

 

380 WHP with only 12psi on a stock motor?
That's a good effort, considering the H22 Vtec has 190 crank HP.

thats awesome to hear brian, but here are the biggest things in my mind.

TUNING:

YOU street tune it yourself. therefore every time that you get into your car you are in control of EVERYTHING. if you sense something is wrong you drop by the shop and burn a new ROM, test it out, etc.

how many people here can tune a car themselves like you can? maybe four or five. i know i sure cant. i would have to go to the tuner, fork out a couple hundred bucks dyno tune it and then be on my way. even with an EMS street tuning for me by me wouldnt be as good as you.

ABUSE:

this will happen. people like me are stupid. we like to hear the woosh and we like to go fast all the time. personally i beat on my car every single time that i drive it. i dont think many people on here have the self discipline you have either. sure i may take care of my car, only giving her good Fuel, oil's, filters and such when she needs it. but come friday, saturday night i am going to beat on her for a few hours.


IF someone had the discipline and knowledge that you do, or enough money to pay a quality tuner like yourself every time they had a hunch then i would say sure, go for it. until then i would still only suggest 6-8 PSI for them.

 

Fly1865 - The kit is one our shop did, all custom except for the SFP manifold

LudeyKrus - I believe top end timing is like 21 degrees, but I haven't looked at the map in like a year so don't quote me on it

Doug - Once the car is tuned, you shouldn't need to make modifications to the map unless some aspect of your setup changes. I'm not advocating people tuning their cars themselves, just the opposite, take the car to a reputable shop for tuning. The biggest mistake a lot of people make is trying to tune the car themselves thinking all it takes is a laptop and a wideband. If you don't have a good local tuner, drive out to one for a weekend. We get cars in from CO, TX, AZ all the time.....
As for the abuse part, all I can say is if you don't have any self control over your driving, you shouldn't ever go turbo. The best setup and motor won't save a car that is consistantly abused. That's a problem with a lot of people as well, they bolt on a drag kit, go out beating on the car, and wonder why it's broken a week later. If someone is abusing their car, it doesn't matter how much boost you're running, something will break. The way I figure it, people who abuse their cars deserve what they get.......

I agree 100%. one thing that Todd told me I don’t think I will ever forget is,

"if you treat your car like a racecar it will act like one"

I am waiting for the day that my Lude breaks. I have had things go wrong with it and yep, they are my fault. That is one major reason I haven’t been too jumpy on finishing my DP NX setup. I know I am going to get stupid with it. Once I get it all on there when I get back I will take it to get tuned immediately. Then I will have you take a look at it if you got time when I am in albacrappy this winter.

Hopefully I will have the respect for it that I do now once it is all installed.

Pix, we want pix! LOL

Back to the topic, remember we're talking about *abuse*, which is different than just using the car for what it's designed for. Abuse involves mistreatment, which is what will kill a turbo car faster than anything. We have people bring junkbox turbo DSM's into the shop all the time with 160+K miles, and they always say "I just got it, and I turned up the boost as high as it'll go, and now it makes funny noises".

One question drake did you have to notch the block when using the SFP manny?

Yeah, I had to notch the block (shaved a bunch off the place where the block is stamped H22A1 and where the top right motor mount bolt went) but the part that was worse was cutting the **** out of the front motor mount (I probably cut off like 2/5 of the front motor mount bracket)....
The problem with my manifold was I got it before 4 bolt housings became the norm, and SFP had designed it for the old ford 5 bolt housings everyone was using. I bitched and moaned about it at the time and talked some trash about SFP, but honestly the manifold has held up great (no cracking or warping) and I couldn't be happier. They are now making manifolds for 4 bolt housings (we just got one for our shop teg) and I'd imagine they make them for the preludes as well now........

This is what I was talking about the mount:
