Choosing a 4G63T for a swap

[Morten Labo]

I have a 1974 Galant rally car that I'm doing an engine swap on.

Initially someone suggested an Evo3 engine... but it seems like a needle in a haystack.

So I guess I'm looking for a 4G63T... a VR4 (yellow 510cc injectors).

Is the VR4 easy to come by ?

Keeping in mind that I need an ECU and an un-cut wiring harness.

Or what's a better bet ?

I'd like to make 260HP with 260+lb.ft torque, and it needs to spool up early in the band.

Who knows a lot about these engines, could answer a question or 5, lead me in the direction of an engine builder ?

Another option is the 4G64 with a 1G 4G63T head and turbo... but I really don't know squat about that, and in fact don't know too much about the 4G63T other than it would make the 74' Galant into a great drift / rally car (I already have a 5 link Dana 30 rear end in it).

Help please...

Is there any reason you are ruling out just a regualr 4G63-t 6-bolt outta a 90-93 talon?? You could find one for fairly cheap, or get 1200 or so from a japenese used engines store.

Basically a 4G63T is a 4G63T.  There's not alot of difference between an EVO 3, Galant VR4 or Talon.  For the kind of mild hp you're looking for a stock MT ECU with a SAFC should be fine and allow you to run up to 660cc/min injectors.  550s will probably do what you want tho.  

A 14b with a big exhaust should spool fast and make good power but an evo3 16g is a really super all around turbo.  

I'd say do some reading on here and keep in mind there's really no difference between the engines with the exception of 6 bolt and 7 bolt.  The evo4+ are signifigantly different tho because they have the head turned around on the block.  Between the regular north american stuff tho there's just the essentially just the 6 and 7 bolt.  

You probably want a 6 bolt but I think some people are overly concerned with the potential for crank walk in a 7 bolt.  Yeah it happens, but then lots of times it doesn't.  I just rolled over 300,000kms on a 93 7 bolt.

Thanks for your help guys !

Does anyone know of a 6 bolt with ECU and wiring harness that's for sale... perhaps out of a donor car that's been smacked in the ass end (can I say "ass" on this forum, not wanting to step on toes already...)

Is this fairly accurate :

"A stock 4g63t and a 16G and 650 injectors with a 2nd gen mass air will see mid 350s HP. So with that setup drop the boost to a very conservative 18Lbs or so and you will be in the 300 range"

Pretty much.  My ol' 2.0 with a T25 was close to your goal of 260 HP on pump gas.  With a larger turbo like a small 16G, big 16G, EVO 16G, or a T28 you shouldn't have any troubles at all.  

For that low of a HP target you shouldn't need to do anything wild at all and should be fairly inexpensive.  I wouldn't even bother with cams, just concentrate on an effective but easy tuning mechanism (AFC, DSMLink) and monitor your criticals (fuel pressure, boost, Air/fuel mixture).
