420A to 4G63 swap

[jwreed09]

hey dsmtuners...i figure this forum has been created before or it's atleast been thought about. But, as some of you know the timing belt on my 420A slipt off and the pistons bent and messed with the walls and the pistons. so yeah! but, my mechanic who has a junk yard has me two good deals! he has a 420A engine for 1100. But the thing that grabs my attention is the other surpise. his buddy is bringing a gst down to the junk yard for parts, it was wrecked in the rear or something. but the mechanic knows i wanna eventually go turbo, and he's gonna help me out hardcore! So were gonna swap everything we need: engine, catback, ecu w/ wiring harness, radiator and etc out into my rs! i'd just like to know what ya'll think about it, and how hard is it? i mean this guy has turbo'd naturally aspirated cars easily, and he's done many of swap. I'll find out exactly what's up tomo afternoon, with price and etc. but like i said he's givin me a good deal and the more i help the less the labor charge is.

don't worry about answering this thread anymore guys. it was a dumb question. i just got home and found other forums! screw the swap! i might just take the stuff off the gst to turbo my 420a...downpipe, manifold, turbo, catbcak, is there anything else? i'll prolly need an external wastegate and the fuel pump....then i'll need custom piping, and bov. what else?

ya dude like the guy above said, you need a manifold. there are few things from the 4g63t motor that can be used on ours. the turbo can, the intercooler can, and the BOV can. thats about it. your gonna need a manifold, downpipe, intercooler piping, among other essentials that you need when turboing a nt. your will also need to modify the wastegate in the turbo, because its set at 11-13psi, which is too high for your NT engine. trust me dude, i was getting the T-25, intercooler, and crushed 1st gen BOV for dirt cheap, and when the math was all done, it would cost me about $200 less then a star stage one kit, and i would have an undersized turbo, and probably many problems. your best bet is a kit, i hated hearing it to, but i realized its the truth.

^^ what he said

 

[jwreed09]

yeah i understand now guys. i prolly should have just waited til i got home to do some research. but i figured hey i'll post a forum and let everyone give me the solution. i honestly didn't think it'd be that difficult for the swap! so i'm going back to my 420A being installed and see what we can do with that! and maybe if that gst is a 97-99 model i'll just strip the rear bumper and side skirts off and finish my conversion...anyone think i should get the wing too? we'll see...maybe even some interior. haha, cause it only wrecked from the front.

didnt u say it was hit in the rear? yes def get the wing

 

[jwreed09]

yeah i thought i heard the mechanic say it was hit in the rear, but my buddy who was there said the front. I also called the mechanic yesterday to find out that it was a 96. and it's not a gst it's a gsx...maybe i can see about gettin that beast running! haha. yeah right, he'd prolly want like 4 grand just for the car itself...and i don't have that much money. haha. but that'd be tight! don't the 96 gsx have like that lip thing kickin on the sides and rear and front? maybe i can strip that off...and maybe whatever wing. did the 95-96 model gsx's come with turbo wings? i don't remember! but here's the deal...while the car's down there, i'm gonna have my urethane engine mounts installed, new engine, were gonna paint my hood and bumper, and possibly install my pillar gauges. but that all depends on how much...but were gonna concentrate on gettin the car runnin first!!!!! i'll let ya'll know what's up hopefully here soon. the car is suppose to be gettin towed down this evening! i can't wait til i get her back! i miss just driving it..haha. but i'm sure all of you have been in this long process of not driving the eclipse...if not, it'll happen! haha
