Hey guys, I have a 98 Accord LX. Just got an imported motor. The same exact one. f23A1 i believe with around 40-60k. The car has a turbo but since the the motor has no internal work done will it mess up? I have 3 friends telling me 3 different things.

Friend 1: You can run up to 7psi before you have to do internal work.

Friend 2: You have to have internal work done to it PERIOD, or it will ruin your engine.

Friend 3: You need to swap out your Cam or it will blow it.

I really don't want to spend anymore money on the car but if i have to I will. I would be using it for daily driving not racing, maybe just here and there on lonely night rides home from the gym.

Would it be possible to not do any internal work to it and be able to drive it daily? How much would the internal work amount to?



Thanks in advance )

 

1. Yes and No. You can run in a range f 1lbs-14lbs of boost depending on the size of the turbo...But saying 7psi doesn’t really mean anything. You can have a bigger turbo that runs at 5psi making the same power as the smaller turbo running 7psi....see what I mean?

2. Yes and No. No you don't have to work the engine over. Any turbo car will have a shorter engine life span than a all motor engine all day long.

3. Don't listen to that kid...has no idea what he/she is talking about. I have friends running stock cams on high hp builds. My boy spiker is running 650hp on stock cams. It can and has been done over and over again.



Did your old f23 have any internals? If so take them out to beef up the new low mile engine.

 

I honestly wouldn't care about not boosting. Is there a way I can disable the turbo? Or would I just have to run it at 1psi? Im not sure how that works. I do still have the old motor but the car was actually sitting there for 6 years so I don't know if parts in it would still work? It originally had a "blown head gasket" according to the previous owner.

How would I go about seeing if it has internals?

 

You wouldn't...It's a one of a kind build car..

 

Well basically I'm going to go with the friend that said to run it under 7 psi.
I'm not going to check for internals because he said the motor is basically done. Hopefully it won't mess up.

Since I am planning on running 4-5 psi and my wastegate has a 7lb spring does that mean it would never open? Can someone please explain this to me, basically I just bought the car for its shell and it would have been too expensive to remove the turbo when I was getting the engine swapped so I kept it and I have to deal with stuff I don't know about. I bought a 38mm Godspeed wastegate. It currently has a 7lb spring and the bottom nipple is connected to the turbo. I called where I got it from and the guy told me seal off the top nipple so I did. Is this setup correct? Can someone please help me through with this? I would really appreciate it. =)

 

I know that u can use eclipse, talon and lazer turbo manifolds on older civics. Is there any modle manifolds that will work on a 98 Accord with the f23 block or do I have to go aftermarket for it?

 

after market. The DSM turbo manifolds only worked on the f22a engines. Just had t drill out extra hole. But you will need to go aftermarket no OEM manifold from other make car will fit your f23 engine exhaust port pattern

 

Brian doesn't run an f series anymore and 650hp was not made on stock cams. Also the f series engines can handle 350 all day long on oem internals. More than enough for a person with limited turbo knowledge

 

I never said he was running a f series he has been playing with h series for years. That’s why the word "cam" has a “s” on the end
And yes a few of his high hp builds ran OEM cams.

 

My POS?

759 WHP 578 TQ @ 8500 RPM was made on Stock JDM cams on a T04ZRS 67 MM turbo at 35 PSI.

650 was made on Same setup @ 29 PSI before, but bore at 87.5mm vs the 89mm Im at now. This time around, car made 700 WHP at 30 PSI, and the 759 at 35 PSI falling to 32 PSI up top due to the compressor being PISSED OFF and done :O)


^The Accord has NEVER had aftermarket cams in it. Period ;O)
