okay obviously besides the fact that the 4g63-t has a turbo and possibly bigger injectors, what are the main differences between the two? lower compression pistons? higher quality/better build? i can find more than plenty plain 4g63 motors for under $700 and a transmission to go with that for under $1000 total around here, and i rarely see a 7 bolt 4g63-t.

keep in mind i'm going to rebuild it while it's out anyways...gaskets/lower compression pistons for more boostability [yes that is now an official word], and maybe some other things.

thanks peeps

why do you want a 7bolt? i'd much rather look for a 6bolt 4g63

 

the 6 bolt is a much harder fit to my car- 98 dodge avenger. very complicated...or rather too complicated for me.

 

You can get a 6 bolt in there. I have a 6 bolt bottom with a 2G head. They share the same sizing btw, it's the way the the two motors mount that's different. The mounting shouldn't be an issue if you're thinking of swapping in that motor because you'll have to weld some motor mounts in anyway, so either one will work....hint, hint...6 bolt motor

 

Oh yeah, the difference between the two. The N/A 4g63 does have a higher compression and it's a 1.8L motor and it's also slower than the 420a and 6g73.
The 4g63 N/A and 4g63T are mounted the same exact way. If you're going to do a swap go with the turbo motor or you're really just "wasting" time, effort, and money. The physical size of both motors are exactly the same, it's the internal boring that is .2 liters different.

 

ah okay. i figured as such. silver, earlier you told me that the 6 bolt can still fit but there is a lot of modification needed, also the ecu needed to be spliced and i was told that it wasn't worth it. so i've been moreso set on finding a 7bolt. is it really that much harder? i'm really looking for ease of the install...i'd rather not have to do much welding/splicing/etc but i know there'sprobably going tobe atleast some of that witha 7 boltanyways. i just want to keep it to a minimum as i have 0 welding skills and i don't think any of myother college buds do either.

but as far as the swap goes, i'm going to be rebuilding whatever engine i get. new gaskets, lower comp pistons, etc before it even goes in. keep in mind this motor is probably going to sit for several weeks to a few months while i get the rest of my resources needed for the swap, as well as turbo/turbo upgrade eventually, but more than likely later on. my main plan is if i end up getting/finding a 4g63-t, i'll keep the stock turbo for nowand only redo gaskets and keep the current pistons, then an adjustable wastegate + boost controller, thenbigger turbo.probably up to 6 months later though. anyone know the compression of the cylinders on the stock 4g63-t? 9:1 would be great...even lower would be amazing. <3 boost. =)

anyways...this is a little off topic but i never could find an answer about one of the issues still in my head. i know that all of the pulleys are going to be relocated with a 4g63 from the passenger side to the driver side. i'm not concerned about the ones with flexible hoses/wires such as the water pump and alternator, however the power steering and the a/c compressor are my concerns as they have pressurized systems with non flexible hoses, and i'd rather not have anything to do with that myself...as i have no ideas of their inner workings. how difficult is that going to be or how much will it cost me to tow the car to a shop and have it reconfigured?

sorry for the long post, it's just that when this happens i want to make sure that everything goes as smoothly as possible and i'll be ready for what problems i will probably encounter. what should i expect?

but yeah, again i'm mainly looking for ease of installation, unless the 6bolt is just so much better than the 7bolt. i can live with a 1.8L since it's going to be turboed eventually and i'll probably have it bored if that's not too expensive either. so anyways: main advantages over the 7bolt with the 6 bolt, how much harder the 6 bolt is to install compared to the 7bolt, and difficulty of reconfiguring powersteering and ac as well as problems i should expect to run into when i do this overhaul.

thanks guys

where does 1.8 liter come into this?? both the 6 and 7 bolt's were 2.0L

 

There's two 4g63's. There's the 4g63"T", which is the 2.0L that everyone loves and then there's the 4g63 (out of the 1Gs also) which are naturally aspirated and it's a 1.8L.
The title above states "4g63 vs. 4g63T"
That's where the mention of the 1.8L comes from

 

yeah the 1.8s were the plain 4g63s. but again with my statements in my previous posts...what say ye silver?

also, how much easier would a 420a swap be? or rather, what kind of power (once turboed with replacement gaskets and low comp pistons) could i expect out of it?

 

[/align]1.8 was 4g62 sohc 4g63 is dohc
