    Is there a difference between the Turbo and non Turbo 4g63's. Just curious and what are the difference if any? Would they work in a Turbo car? Are the heads the same? I don't know kind of dumb question I know.

    Yeah I know the difference between 420a and 4g63. I have a awful talon as well as my rs. I have access to tons of non Turbo 4g63 engine's. And a friend of mine has a no Turbo head I will buy if it will work on my 96 awful talon. I bought it with a broke t belt for $300 I also bought a 90 6 bolt Turbo engine come to find out it has bent valves as well I just want to get this car back on the road. I'm putting new bearings and all gaskets in it while I have it apart as well as all fluid change all u joint and all that stuff matenince wise.

    your fine interchanging the heads. The compression ratio is not the problem with the non turbo pistions its the thin ring lands. Non turbo block is okay with turbo pistons. you won't have oil squirters and there is some debate on that but lots of people run without them.

    As for the head, yes it will work. You may have to swap out cams for turbo cams, and the bolts are bigger on a 2g

    Sweet that's good to know I might just have to start buying them to have as spare blocks as I plan on drag racing and at some point would like to breakers 1000 HP at the crank so a spare block or two wouldn't hurt.

    the only difference between Turbo and non Turbo 4g heads is the exhaust cam is "bigger" in the Turbo head

    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.

    I have all the 6 bolt parts to do this then as I bought a complete 6 bolt even have all the plugs for the sensors and all. Thank you guys for clearing this up. I don't plan on using the non Turbo pistons at all.

    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.

    Why not just buy new valves? You can get new ss valves off 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
    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

    Not unless the guides are worn. But honestly, considering how cheap you got the car, i wouldnt complain too much about a couple hundred spent on the head. My personal opinion would be to stay with the 2g head. Then you dont to worry about the cas, buying a 1g intake, etc. Then build that 6 bolt and drop it in later

    Yes. They are the same bore. The only difference in the n/t 4g63 and the 4g63t blocks is the absence of oil squirters

    another thing you have to keep in mine is the intake cam is differnt on a 1997-99,it has the slot cut at the end for the cam sencer,but you can use any non turbo or turbo head and it works .

    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.
