[TurboEclipes]

Ok guys need some help i have read all the threads about swaping these engines but none really didnt just come out and give a straight anwser ok here is the thing, I have a 90 Eclipse FWD GST and a 97 Eclipse Spyder GS FWD, My spyder has the 4g64 N/T motor in it and my 1G eclipse has the 4g63 turbo in in both cars has 5 speed trannys.I want to make my Spyder a gst by putting my 4g63T motor in it ok i need a simple anwser will this be hard thing to do and what do i need to do?You can also email me and give me info at [email protected] pls help guys thx

Did you ever park your to cars side by side and look over the motor mounts, and the relationship between other key components?

Anything can be done...with the right amount of money and a LOT of patience. But like 90laserRSfwd said...mounts and other miscellaneous things will need to be relocated and fabbed. For the most part, unless it's a 7-bolt to 6-bolt swap...DSMs aren't the car for engine swaps.

I did a quick search through photos and found the spyder n/a motors to be facing the same way as all turbo dsms (thought so but had to make sure). Now im not 100% on the engine mounts and such you will have to check that yourself but i did have a friend witha 4g64 turbo project that was running perfect. The 4g64 motors are 2.4 liter so if you turboed THAT then you could have an equivalent to a stroker But if the engine mounts do line up then swapping the 4g63 would be a good and much cheaper idea as well. Just something to look into

Just turbo your 4g64, its MUCH easier than swaping the motors but anyways everything bolts in (except the axels) for what you want to do. There is other odds and ends you have to do to make it work but I'll let you research on that.
But think about it...at 10psi you'll be making 20 more whp and like 40 more ft/lbs with the SOHC head... if you turbo your 4g64 vs a stock 4g63t. Honestly it doesn't make sense to do the swap if you have a perfectly good 4g64 already

I always love how some people here N/A spyder and think its a 420a enging instead of the 4g64.

Here is a very helpful link.

Its not easier to turbo actually.

Its not easier to turbo actually.

I'd would rather just bolt on an IC kit , downpipe, and turbo assembly and plug in a GST/GSX ecu tune and be done then pull two seperate motors and install AND do all that extra stuff to get it running.

 

[twoTSis]

Agree wit moneypit...turbo it rather than swap. OR buy another 4G64 built it and turbo then drop it in and sell your original 4G64 motor.

HOWLy crap!!!! Do you guys actually think a 4g64 is more durable than the mighty 6-bolt 4g63 he's tryin to swap into the spider????

1. weaker pistons
2. Weaker head bolts
3. Weaker rods
4. Terrible rod/stroke ratio
5. No oil squirters
6. More crankwalk prone (not this should be a worry, but I'm on a roll)

Especially considering he has a 14b on his 1g m/t gst!!! This turbo is 300+ whp capable. the stock 64 has done it. But don't think your next turbo option will see a durable STOCK 64. The 6-bolt 63 can push 450whp with ease and be very streetable at it's hp limit.

Back to the original question. Follow the link Cs4g63 posted. It's a cake walk compared to a honda b-series swap.

Hey this guys asking how easy it would be, not the power...

 

[dsm-onster]

You're suggesting swapping just turbo components for the sake of easy install. Picking up the pieces of a 64 block is not so easy . . .

It's really the easiest just to toke some nitrous. That's makes me laugh (no pun intended).

 

[98gsspy]

It redlines at 6 grand, its a bad turbo platform to start with. I wish I would have swapped sooooo much easier.

 

[twoTSis]

Get the man a thread to tell him how then!! The previous linked thread that was posted is more or less just a list.

 

[link16]

That "list" has the nitty gritty work and how to do it. If he doesn't know how to do a basic engine removal and install, then he should put down the wrench and back away slowly.

1. weaker pistons *no worse than an NA 6 bolt*
2. Weaker head bolts *no worse than a regular 2g*
3. Weaker rods *no different than a 2g*
4. Terrible rod/stroke ratio *same as a stroker, will rev to 8k no problem all day long*
5. No oil squirters *they rob oil form the crank, with forged internals it wont matter*
6. More crankwalk prone (not this should be a worry, but I'm on a roll) *pppffftttt*

now the corrections above being made, Put a 4g63 head on your 4g64, get DOHC 4g64 cam gears and timing belt, all the turbo components and run it.

If you guys still want to talk your normal BS, my friend has a 3g with a SOHC 4g64 and a 16g, makes about 285 FWHP and has been turbo for several years without issue.

Turbo'ing a 4g64 isnt that bad and can handle it, but its when you really want to put on a huge turbo that you will run into problems with the weaker internals.

He can't run good 16g power for long. A 14b can make 285whp. Why the laggier turbo? At 350whp, one bout of mild detonation and piston lands are cracked. I'm speaking from experience. It's reliable if you run a weak tune under 300whp. After that, possible detonation will lead to certain piston cracks. With a 1g or 2g turbo block, possible detonation will lead to possible damage. The stakes are simply VERY high with the 64 pistons. The original poster chose not to gamble under those odds.

The corrections can't be made for cheap. . . which is only really one. Forged pistons (since you can't put 63T pistons into 64 blocks). He can get a whole 500whp capable 6bolt block for the price of the pistons and not have to pull it apart. Then he'll have to add the cost of head gasket and other gaskets. He'll have a block still stronger than the 64 with forged pistons, too.

Nevertheless, this IS an option. And you'll have quicker spool and more lowend torque.

Running 10psi is the MAX limit, you will be lucky to make 220hp maybe.

 

[OddNotion]

A guy with the same car as I runs a 14b and occasionally spikes to 15PSI and he has been driving for years.

It is a fun street car. Bolting on a manifold and some intercooler piping and other things is going to be a lot easier than HOISTING an engine out. You won't even have to remove the transmission

OP, you ought to join the Yahoo 4G64 group and read up there before you make a decision. It's all about your performance goals.

Exactly!

 

[olschooltuner]

So after reading all this am i understandimg corre tly its better to run a turbo 4g64 as long as you rebuild the internals? Say..... A crower build kit.? Im new to the sohc 2.4 i have always messed with the 4g63s out of talon tsi. I actually just picked a 97 spyder gt and have both the 4g63 and 4g64 core engines just trying to decide which will preform better
