SE-R or swap dilemma and questions.

I've been contemplating on whether to swap an SR20 for my 1.6 or just to purchase a B14 SE-R. I'm pretty sure I could do the swap myself, it doesn't sound to hard to me. I've just never swapped motors in an import. The wiring actually sounds to be the only difficult part of the swap (Maybe that and coming up with the money for parts). However my problem is finding either a.) a junked and running SER or b.) find a front clip.

I have also thought about just buying a B14 that already has an SR20. My problem though is that I haven't found a SINGLE ONE. The closest one I have found is about 1,500 miles away! That's a bit to far for me to just pick it up and I don't even wanna see the cost of shipping that sucker here.

Do I have any other options that I just don't realise? I don't want to just turbo my GA because it's not enough power for me. I want at least 250-350 horses, so I'd like to see anything from high 11's to high 12's. I'd like to either have an SR20'd car or the motor swapped in this winter. I was planning on getting a CF hood and then starting to save up the dough required to swap the motor but I'm not sure if that is my best bet.

Working on car's isn't hard for me, and anything I don't know I pick up terribly fast. I have a $6,000 sq-ft shop available to me to use and more tools then most shops. I swap motors in muscle cars all the time. But that's a little different because I just slip it into the tranny and drop it on the motor mounts and start tightening bolts. What's the average down time for a car doing the swap for a person that hasn't ever swapped the SR20 but has experience with other vehicles?

Also, I'll say it before someone else does. I have researched this, I have searched the board, and I have read TONS of posts on the subject. Hopefully these are specific enough questions for you as well and I'm not asking identical questions to those that have been asked previously. I'm aware of power levels, cost and all that other stuff except the above posted questions.

I was also curious on when turboing an SR20DE, do I need to drop the compression any? If so what is the easiest and best way to do this? I've never had to lower compression on a car. Raised (To 14:1 on an '67 Mercury Cougar that was used as an 1/8 mile drag car), but never lowered.

Thanks for any help and I apologize for the length of my post. If I got anything wrong feel free to let me know. I rather be correctly informed.

I don't understand. Do you mean swapping the SR20 in would be the ultimate sleeper? I guess that kinda would make sense. Right now in my car group, crew, team... whatever you wanna call it. I'm the slowest. With an SR20 with turbo I'd probably be the fastest, I wouldn't know for sure though unless I did it and we ran each other at the track. Right now our fastest is an SRT-4 and a Dodge Stealth R/T running 13.9's.

And PSULemon, as I said, if you would have read it, I can't find an SE-R. And for one thing I just finished fixing all the problems with this car. If I do find an SE-R I'm sort of afraid to buy it because I don't know what is possibly wrong with it.

I think it would be pretty sick to swap in an SR20 though. All my friends are pushing me to do it too because they know the potential it has.

Man, I wish this was easier.

if you can't find an se-r to buy, then why are you asking if you should just buy it. Buyin the se-r is a lot less hard than a swap. And doin the swap isn't goin to make it a sleeper. Things that make cars a sleeper is what is done with teh exterior and things like recirc BOV (if turbo) so people dont know what you are running. sleep is just low profile.the main differences in appearence are little from the se-r to the se. the se-r has skirts and bigger and nicer rims and rear disc. any car can be a sleeper. i just means stay away from euro tails and other ricey stuff concealing your intercooler and not running a BOV but rather a bypass

I know what a sleeper is. You didn't have to explain it. My friend used to have an 89 Galant. It looked like complete ass, but it had a turbo and was quick. It was a sleeper.

Mine is mostly stock on the exterior. I added some driving lamps to it. I also have some 17" rims and some black euro tails.

I actually managed to find a 200SX SE-R last night. That was actually amazing. Thing is, the price difference for the car is MORE then it will cost me to just swap a motor in. Also, if I just swap the motor it'll also cost me less on insurance and car payment. Because if I buy an SE-R my insurance will raise and my car payment will be more because it cost more to purchase.

I really think I'm just gonna swap the motor. It sounds like the cheapest route for me. It may be harder but I'm confident I have enough skill and experience to complete this project within at least a week if I devote enough time everyday/night to it.

I have a question though. For the wiring harness, I saw a place where you can buy it, I think it was JGY Customs. My question is, are all the wires labeled/tagged so I know what they hook to? Also, I know I need to get different motor mounts... but what about tranny mounts? Can I just reuse the GA mounts? I haven't seen any topics about it.

Before I forget, what place is the best to get a good low-mileage SR for a good price? I've been told and read about Nippon-motors. But I haven't heard anything about quality or service about them. I'm gonna start buying required parts for the swap next month.

Oh, thanks for taking the time to help PSUlemon.

You say you've searched but you ARE asking many of the same questions. JGY has the parts needed listed on their site.

No the harness is not labeled however the connections are self explanitory based on cable length and connector style.

Mount wise JGY has th emounts needed on their site.

SOKO is a good place to buy engine's from, I have seen three motors purchased from them and they were all in good condition.

if you have done other swaps before you can do this one, just make sure you research what all is needed sot hat you are not stuck ordering parts in the middle of the install.

I know JGY has the parts listed.. I have the page book marked. I just was asking if the harness was labeled and whether or not I need different TRANNY mounts because I haven't seen anything about it. I know that I need the MOTOR mounts and the brackets. I know everything else that I need... I think....

I'll also make sure to check SOKO out. Thanks.

The tranny has ONE mount, which is actually in turn a motor mount (driver side). That mount is the same, as are the rear and front (dog bone) mounts (same as your 1.6 mounts). The passenger side is different.

Actually I found one. It's some 60 miles away from me... but now it's mine. I bought it tonight and have to pick it up tomorrow after I give the paperwork to my bank.

So I don't have to worry about the swap now. But I believe the GTI-r should be an identical swap.

I was curious though. Will the JDM SR20DE bolt right in if I pull the USDM motor out? Or do I have to change trannies also?

the jdm trannies are awd for im pretty sure almost all the jdm sr20dets, so it should be a direct swap.

The biggest difference on the gtir swap over the bluebird, is you have to splice the gtir injector harness on to your normal sr20 harness...because the gtir uses top-feed injectors which use a different plug than the bluebird or sr20de. And if I remember correctly, on the gtir one of the transmission bell-housing bolts is no longer used(maybe all det's are this way?)...anyways, thats my .02!
