Ok well as the title states, I am goin to boost my teggie in about a month. I recently did a compression test , and my numbers were 195-195-195-190. The catch is that my teg is about to hit the 200,000 mile mark, but the engine purrrrs like a baby, tranny shiftes like the 1rst day off of the lot, and I have no mechanical/electrical problems whatsoever.
Now I've heard that when it comes to boosting Hondas, the first things to go are usually tte rings and the piston rods. my question is this . I really didnt want to pull the motor and build it right now, I just want to hang the hairdryer up as it is and run no more than 8 lbs of boost (controlled by a wastegate spring). Even though my engine and tranny are completely mint, Do you guys think it is wise to boost on piston rods and piston rings that have 190,000 miles on them ? Also, what is the max lbs of boost that you would say would be safe for a daily driven, 190,000 mile teggie ? Thanks guys

 

It's really not the rods and rings that you have to worry about, at least at 8 psi. The rods are definately strong enough at that boost level and guys use stock rings on 400 HP cars. The problem lies in the stock cast pistons. The ring landings, the area between the combustion chamber and rings are not strong at all on the stock pistons. This area is usually the first place to crack and you'll start to burn oil.

I would say you'd be fine boosting your motor, but I wouldn't go higher than like 7 psi (it totally depends on the turbo) on your stock, high mileage block. The BIGGEST thing that you have to may attention to is tuning and fuel mgmt. Don't go the FMU or AFC route if you want your motor to last and have it running as best it can. If you run lean and start pinging then you're going to kill those pistons. Go with some bigger injectors and then, if yer on a budget, go with Uberdata, Neptune, or some other relatively inexpensive fuel mgmt. I would base what fuel mgmt you get on what tuner you are going to use. Finding a good tuner makes all the difference in the world. I good tuner will have your engine running as smooth as possible as well as being conservative in the fuel and timing areas. I don't know where you're located but in PA I would recommend Evan. He's got a nice website at http://www.boosted-hybrid.com. You can also check out his dyno plots from his tuning on his dynojet on there.

Also, search around the FI forum as much as you can. There is so much helpful information in there it's not even funny. There are so many guys that know their **** in there. Good luck.

 

thanks alot dude...any other opinions ?

 

start researching this from proven sources, they have some really good books on the subject, i like Maximum Boost but its expensive

 

sweet..thanksa for the info guys
