Newbie Forum - Beginner/newbie/general DSM modification questions. First mods, how to run 10's when you haven't run 12's yet, any tech question that doesn't fit in another tech forum.
Good point about the bolts. missed the part where you were putting it in a 2g that makes it more involved you need to use the 1g manifold to match and that raises more problems with the coils and sensors etc.
This was a very bad post on your behalf. If you do not know anything about the 2 engines then I would not be posting misleading information.
The non turbo 4g63 carries all the same parts as the turbo version minus the pistons and the oil squirters.
They are the same engine, same crank and the same rods. You can use the non turbo motor just fine without changing anything but keep boost on the low side due to the pistons.
The compression ratio really has nothing to do with it either.
Well there's the oil filter housing as well that's different. Mounts the exact same but the turbo's have either an oil cooler set up (90-91 I believe) or a liquid cooled filter housing (92-99).
Then use the 6 bolt with the n/t head and the turbo cams. One problem is wiring in the 1g cas. But you really need to read this http://www.dsmtuners.com/forums/articles-engine-fuel/152329-how-do-6-bolt-swap-what-you-need.html first before you decide to undertake this. And if you do, i would suggest freshening that 6 bolt up. Might as well since youre going that far
I want to use the 7 bolt for now and build the 6 bolt for power when I get the funds together to do so. I have read how to do the swap and plan to do so. Or is it really going to be worth just using the 6 bolt now? My talon is an auto trans by the way. With the factory LSD in it. If it will be a better set up to run the 6 bolt ill go ahead and do that but I have almost all I need to do a rebuild on the 7 bolt.
eBay for less than $100, lap them in, and install new lifters, and poof your done. Assuming of course that the valve seats werent damaged
I am assuming that I would have to replace valve guides as well. I've thought about that too. I've heard good things about the $100 eBay ss valves. Idk what to do. I can get the NT head cheap. Idk
Yes. They are the same bore. The only difference in the n/t 4g63 and the 4g63t blocks is the absence of oil squirters
The 1g 4g heads dont just bolt right on. The holes have to be reamed out for the 12mm headbolts, the 1g cas either has to be wired in or removed, the coils have to be relocated or swapped with the 1g intake AND tb
Its cool thats why i just suggested its best just to replace the valves on the stock head vs the trouble of swapping
You have the head bolts backwards... 1g/6bolt have 12mm head bolts, the 2g/7 bolts have 11mm
so a 6 bolt block with the 2g/7 bolt head has to have the head bolt holes enlarged.
Ohh oops. Thanks for the correction bogus. I get turned around sometimes
