If you have the F22A4/6 exhaust and the F22A6 intake with either a pt3 converted to a pt6 or a pt6 ECU I would go for it and wire in the IABs if you haven't already. The new springs can't be in worse condition than my 20 year old springs.

Get a windage tray while you are at it. There is a lot of power lost to oil clouds in your crank.

Right now I don't have the butterflies set up but they are deleted with an H23 IM. I think I have more power in the mid and high range and overall its better for my set up with 0.50 OS pistons. The P12 ECU I have in it now is doing me good with the H23 manifold.

I have the windage tray its just I don't wanna mess with the oil pan gasket again I already have done that like 3 times since the rebuild. Anyways I wanna put this camshaft in but I don't wanna mess anything up. My brother last time had the neighbor try to change the lower spark plug seals and ended up destroying the rocker arm assembly by not re installing it correctly. It was a crack head move by rednecks who didn't know what they were doing, I don't know what I was thinking letting them work on it. My brothers really took the initiative to do it, they thought it would help. Didn't help at all, had to kiss the whole top of the engine goodbye. Now I have a rebuild head.

Anyways. This is the place I got the cylinder head from:

http://www.japanengine.com/products/...&search=&page=

It says it has "reconditioned/replaced" parts including the camshaft. The A6 camshaft I wanna put in has about 200,000 miles on it. Now I am sure this place did not put in a new camshaft but one which was used had more than 100,000 miles on it. Be that as it may should I still install this A6 cam even though it might have more miles than the cam it has on it right now? The A6 cam I got from the JY is in good condition. I think it could be an easy swap as long as I get the timing right and such... don't wanna mess that up. Also the rocker arm assembly...

Is it still worth it and will it give me more power? I am sure its easy to replace, all I have to do is replace the old A1 cam with the A6 by removing the rocker arm assembly. But removing the timing belt, that's not hard I did that before. All you have to do is loosen the timing bolt and removed the belt, then make sure its at TDC before you remove it, then install the new belt and camshaft. Easy as pie : )

What I wanna know is if its a good idea to install the more aggressive F22A6 camshaft to a F22A1 head that does not have the "stiffer" valve springs?

Yes. It works fine.

Will this set me up for failure in the long run and can the springs handle it?

They can handle it. I'm running a 272 delta with stock springs and revving to 7600rpm.

Mind you that the cylinder head I have on it now is a rebuilt unit and only has about 40,000 miles on it. I bought it from a place that said they put all new parts in it. This would include the springs no doubt. I talked to the guy on the phone and that's what he said.

I am thinking of either selling it or using it myself. Which one would you choose?

The head thats on it now is rebuilt. I got that. But why would you sell it? That part makes no sense.

edit- Now I see that your referring to the camshaft.

**2winRB25** · 07-27-2013, 05:06 PM

Is it still worth it and will it give me more power?

Yes, however the A6 cam is designed to be used with a PT6 ECU. I would not try and run it with a P12.

Be that as it may should I still install this A6 cam even though it might have more miles than the cam it has on it right now?

Don't be concerned with the mileage on the cam. As long as the cam is in good condition and not marred its good.

That maybe true but the P12 ECU makes 10 more HP over stock. I think I should put it in and see what it can do. I am just worried about the timing and such. I betya it'll be a good improvement over what I have in it now. Don't underestimate the P12 ecu, it probably can adapt to variations in the engine. The ecu will adapt you just have to have faith in it, it is a engine brain after all and it can think for itself.

The P12 is not tuned for an A6 camshaft. Plain and simple. I'm not saying it won't run well and you won't see gains. I'm saying its not optimal. They were not designed to run together.

I'm not putting down the P12 so idk where thats coming from. If your going to go with what you think is best based on your knowledge you had prior to creating this thread I won't waste my time trying to help you.

I don't have faith in anything. I go by knowledge and proven facts, not word of mouth, assumptions and guessing.

**wildBill83** · 07-27-2013, 07:26 PM

I'm assuming you are using the popular butt dyno to measure your assumed 10hp gain from a p12 ecu. Also you gain nothing by gutting the IABs unless you are running a forced induction setup. In reality you have never used IABs so you actually have no clue of the benefits you are missing, if you did know then they would be functional. Also you never discuss your exhaust setup, if you don't have a 4-2-1 equal to or better than an F22A6 exhaust then it won't be optimal.

If you ran that cam on a p12 ECU you might just be asking for a loss of power.

I'll make it easy for you. You should just sell the cam, and sell it to me. I'll use it as it is intended with a matched ecu, intake and exhaust.

ECUs don't think for themselves, they don't "learn" or write their own maps, if they did no one would ever need a tune in the first placed... SMDH

Okay so I just swapped the cam and all went smoothly except I accidentally broke off one of the 10mm bolts near the distributor. It broke off right where the end on the high side so I should be able to replace it easily. What I just used for now is jb weld on the bolt and on the seam where the dizzy is and hopefully it will be alright. I am sure its no big deal. Its just a 10 mm bolt where the dizzy is, there are already 3 dizzy bolts holding the rocker arm down to the cam.

**wildBill83** · 07-27-2013, 08:30 PM

What is with you and JB Weld? Epoxy doesn't belong there... Buy a bolt extrator kit and replace it correctly. That's not smart. It would almost be better to run without the bolt and fix it later than to epoxy down your dizzy end cam cap.

They do matter. All of them. They are all needed and are needed to be torqued to spec.

Is it one that is one of the studs on top of the bolt to the valve cover? That happened to me (because someone else had been in there at one time fucking around). If thats the case you got lucky because the bolt/stud can still be turned. If not that could be a royal bitch and it is a big deal. You broke a fucking bolt off in the head.

Like wild bill said. Get an extractor kit (if you broke a bolt off not a bolt/stud for the VC) and get that JB weld out.

Well the JB weld is only in the bolt hole and on the outside where the dizzy is and not where any oil is (inside the VC).I really wanted this to be a permantant solutoin cause I just don't have time to fizzle with it anymore i'm too sore.

No its one of the 2 bolts for the rocker assembly where the dizzy is. Its on the far left of this diagram:

**Mishakol129** · 07-27-2013, 09:24 PM

I just took it for a test drive and its definitely faster than it was before... The car breaths more than it did before.

**2winRB25** · 07-27-2013, 09:37 PM

I have only been into that part once and that was without any problems. So I can't be of much help.

Wildbill should be able to continue helping with this matter.

Good luck! Glad you happy with it!
