Or a rebuild can be done with better than stock performance for under $1,000 including machine work. That's all I meant to get across ....

Very well put... And just to emphasis a different point... the eclipse was NOT made in japan. Never was and never will be. Or at least i don't see what would motivate them to ever make it in japan... Anyway, j-spec motors are nothings big. Engine is the same, aside from the possible chance of getting larger injectors and the 16g turbo.. but you don't need to spend $4000 to get that crap. As for the cyclone intake... there are a few people who have managed to get it to operate properly and it does wonders for low end. However there are many people who say its worthless and doesn't do a damn thing... results vary obviously because there isn't enough interest in the intake for anyone to actually create an installation kit for it to work properly. As for flow, i do believe it only flows about 2 cfm less than than our stock intakes here in the US. Whoop-de-####in-do. In the end its all about preference. If you've got the money and you're all about the "jdm" scene and whatnot, then go ahead and blow you money on it.

i want to be included in this thread due to me getting an engine in 3 weeks... i have a fwd 93, is it true that it cant take the 6 bolt engines? i have to use my stock tranny in order for it to work.... 6 and 7 bolt are read and silver differances, right? i would like to have my car running ASAP but if its better to rebuild, i will... thing is, i want a dsm colt in the next couple of years, and would like the old motor for then... comments?

the jdm 4g63t as higher compression,? right, so wouldn't be better than rebuilting your current U.S 4g63t?

 

[deezhybrid]

The JDM engines have the same compression as the 1g engines, 7.8:1.

 

[Tsi4eVer]

even the evo 3?

 

[deezhybrid]

From the research I did which was a pretty fair amount, the only differences of the EVO I, II, & III was the addition of the larger turbo and injectors. They may have upped the compression in the EVO IV but that is irrelivant as it resides completely opposite in the engine bay as ours. Your main benefits to using a JDM engine is cost to rebuild. You can get an engine for about a grand or rebuild for 1500-2000. Don't plan on using the turbo and accesories provided though. If they work, great. But remember that they are coming from cars around 10 years old. My turbo I got was good other that the compressor o-ring. You know how the are supposed to be rubber? Mine was so dried out it was hard like plastic. A new o-ring and it worked just fine.

I need info from you people with the purchasing experience. I want to know where (on the east coast) you got your 6bolt from and how much did it cost. I'm seriously needing this info because in a couple weeks I'll finally have the money to get the motor. My 7bolt finally developed a lovely case of crankwalk. I haven't quite gotten to the point of calling all the numbers on RRE's website yet, but if I can't get some good recommendations from you guys then that's what I'll have to resort to. Thanks in advance.

Because six-bolts are everywhere and junkyard guys are letting them go for a song and a dance everywhere you look. Right.

When my 1990 N/T motor crapped the bed on me two years ago, I looked around for a new NON TURBO motor for the car. I was quoted 1200 dollars for a USED NON TURBO MOTOR that I'd have to pick out myself in a junk yard. Thanks, but the car got sent to the wrecking yard. The car wasn't worth 1200 bucks to get it fixed, despite the fact I had loved it and what not.

When my seven bolt went to pieces on me, I searched high and low for a US motor. I looked up, looked down, looked all around. I was quoted 2k for a used motor from a bunch of junkyard guys, and told them to go stick it where the sun don't shine. So I decided to go JDM. I couldn't afford a built motor at the time, so I went for a used motor.

Any big 16G motor with yellow top 510 cc injectors you get, you're going to pay through the nose for it. Vendors of JDM motors have wised up over the years. EVO motors are going to be very expensive, as I called a few places up, and they all wanted over 3k for a 7 bolt, with a crappy 2G teeny tiny port head, and other crap. No thanks, guys. I already have a snazzy big turbo and goofy stuff.

So I decided to go sixbolt, with a Galant VR4 motor. Let me tell you something,DO NOT BUY ANY JDM MOTOR WITHOUT A COMPRESSION TEST RESULT.

Let me say that again in big huge letters, because this is the most important thing of any motor you buy:

DO NOT BUY ANY JDM MOTOR WITHOUT COMPRESSION TEST RESULTS!!!

If they don't give a compression test result, don't buy the motor. That's it. If they can, and it sounds good, you've found yourself a very good motor.

My GVR4 motor has a dead cylinder, and unless I pack up my motor, strap it on a crate, and ship it back to the company, I'm, put bluntly, up Shit-Creek without a paddle. Thankfully, it'll only cost ~100 bucks to fix, but that's 100 bucks that I didn't need to spend in the first place. My JDM motor was EXTREMELY clean, however. Barely any carbon buildup on the pistons (I've yanked the head), extremely clean valvetrain, beautiful looking bottom end, and a perfect condition 13B (Makes a great paper weight).

It's very heartbreaking to prep a car for an engine swap, drop it in, complete everything, and then have the car run like absolute crap, which ends up to be a dead cylinder.

i dunno man. i haven't had any trouble finding cheap 6 bolts for sale around where i live. sorry to hear you had such a hard time.

 

[cait sith]

No problem, it's just that some of us don't have junkyards/millions of dead cars to pick around...

I'd reccomend getting a used US motor over a JDM motor, if only because you can check it out yourself, but sometimes it's an option.

We cool!

It's all in the luck of the draw guys when you are dealing with used stuff. My JDM requires a little work but it's been pretty decent. I paid 1190.00 shipped to my shop. Guess what I bought this weekend?! '92 talon AWD with a very ggod motor in it. Head was rebuild 2,000 miles ago. Unfortunatly it is an automatic. But it runs great. The motor will make a perfect spare if this one ever goes to waste. I only gave 200 for the car. They let them go cheap after the entire passenger side had a disagreement with the guardrail. Nobody was hurt, so I don't have a guilty conscience.
