4G63T (turbo eclipse) internals question

[bcjammerx]

Ok there's a likelihood that I may have access to an eclipse gs-t that a fellow coworker of mine had but got impounded. Something massive broke on the suspension and car isn't drivable...he left it at a gas station and isn't going to try and get it out of impound.

I'm not looking for insane power...I'm looking for a simple build that will give me some gains...just to get some exp. with turbo tuning. And I can't think of a better project then the dsm turbo setup. Also, I don't want to do anything to greatly reduce the life of my honda.

I know a turbo will reduce the longevity of the engine...so I'm not looking for a lot of power...maybe 200 area...why bother with such low numbers you ask? Well like I said...I might have the opportunity and I want to keep the accord running well...and I need more experience before I go for 300-400 range. Of course for now I'm just going to buy the parts. I won't install until I can rebuild the turbo and some other things anyway

I've done some searching and found that the bore and stroke should work out...but what I can't find is this...

How are the internals of the 4G63T built? Are they forged rods? How are the pistons built?

From the reply in this thread , I take it the rods don't go in easily or simply.

I doubt the junk yard that has this car (if it has it) would let me take JUST the turbo, manifold, and injectors...so I'm looking at the whole engine. If that's the case I'd like to use as much as I can, but ONLY if the internals are stronger than stock f22 and only if they go in without a lot of fabbing.


I know I'll need the turbo, manifold, and injectors for this swap...but I don't know about the internals of the 4G63T engine...and I can't find anything out about it either.



Next question...how will the stock honda internals hold up to 8-10 psi with this turbo?

[deevergote]

Which gen is it? 1st gen had the 14b, which is small, but works. 2nd gen had the t25 I believe (I could be TOTALLY wrong... double check me please!) and that was even smaller. The 2nd gen manifolds are reputed to be stronger, but the motors are known to have crankwalk issues (after 100k, if it hasn't happened, it probably won't happen).


It's been researched that the pistons will fit, but that's as far as I've seen. I haven't read on the rods, but I would assume that they might be an issue as well.

I don't know what they're made of, but knowing the Japanese companies of the early 90s, they were probably cast pistons. The stock boost pressure was 11psi, I believe, and that's still even within the range of F22A tolerances (on a good tune... which a factory tune IS) Hell, the Supra had cast pistons, I believe!


It's worth a shot, but all the little things involved might make it more of a project than expected. You might have an easier time just getting the 4G63t into the CB7! (always wanted to try to work in the AWD setup...)



The stock F22 internals will hold 8-10psi no problem, as long as the motor was in good shape when they went on. You'll need to tune to make sure things are safe, but overall, they'll be fine. Hell, straightedge is running 20psi (and making over 400whp) on a stock block with 112 octane race gas!

I think that the t25 was on automatics and the 14b was on manual trans cars, but I could be wrong.

Thanks for the replies!

I'm not sure if it's auto or manual, and I'm unsure of the year. The guy doesn't know much, but he knows enough to know it's stock turbo. Hell I'm not ever sure if the car is up for grabs

But since the internals are prolly not forged, I'll see what they want and what I can get...IF...it's up. Keep what I want, keep the f22's internals, and sell the rest

that's a lot of "if"s though


I know someone else I should ask...KeelesKustome...after all he does drive a gsx
