Does anyone have input about a high mileage car adding a turbo if it has been running fine with some newer parts added (fuel pump, wires, plugs, distributor). I want to do the dsm turbo project on my f22a1 prelude. I have heard alot of people do this project but I want to know if it will be safe and what the limit of boost will be I was thinking at max 8 psi. Ill prlly go with 6 or 7. Also I am going to use mostly all dsm parts (like the turbo off a 92 auto eclipse, 2nd gen ex. manifold, o2 sensor housing) except intercooler, piping, and BOV. ANy info would be awesome. ..
PS does anyone know if the DSM turbos need the coolant line ran if your running low boost like what i want to do , cause there are 4 ports on the turbo , 2 for oil in and out, then the coolant ones...not soo sure ????

 

i am no expert, but here's an example. My 5th gen prelude has 112k miles, nothing major done to it, except the normal maintenance (plugs, oil change, timming belt, etc) and it runs stronger then other ludes with low miles. Did i mention im boosting this high mileage motor

 

Telling us the mileage might help because to some people high mileage is 112k and to other 250k is high.

 

Auto DSM's had a smaller turbo then 5spd DSM's and aren't to much more.

The average folks would think anything over 80k is high mileage. I say do a compression check and if it turns out good numbers, mileage dont maan anything.

leakdown will tell more than compression check, but do both...then come back with the results, otherwise a 50k motor could be much worse off than a 100k motor depending on how it was driven and all kinds of variables

 

that turbo is way to small, what are you gonna use for fuel management? the DSM manifold/turbo requires you to cut webbing on the transmission, not sure if you wanna do that..

 

I think you would need the coolant lines hooked up to your coolant. SInce the DSM turbos are all watercooled. I have thought about this project on my H23 since I have a spare parts turbo DSM. I think 7psi with that accord engine isn't bad. I believe it is the best stock block honda motor to turbocharge.

 

Hey, It sounds like you know something about this kind of project and or dsm turbos?!!? I hear you can plug the holes for the water cooling and just use a turbo timer..?? I would love to hear what u think of it in my situation cause I really want to boost my car..... Im going to use the 450cc injectors off the dsm's and im not sure other than that, Ive been looking into alot information about that kind of thing, what would you suggest??? and the transmission cutting, where at would that happen ?
