how to swap a 2grfe V6 into a st204 - 6G Celicas Forums

Topic #93458 264 posts Started by njccmd2002
My cars now and my last car were all drive by wire.
I have to say I miss direct throttle cable soooo much. The only good drive by wire car i've driven extensively is the E46 M3 otherwise.

Are you keeping AC?
Yes. Everything will work. Crossing fingers

DBW is bad on stock ECUs. On standalones however it's nearly the same as cable throttle. It responds just as fast, but the direct link feel is lost, because the pedal almost always has less resistance to it.

True. But 275 hp in n/a. With spare parts stateside is appealing to me..

I'll bet you can take the pedal apart and install a firmer spring wink.gif

You are a crazy man. Crazy genius. But still crazy! I honestly can't even imagine the work just to do the pedal! I'm going to have to come to TN so see this beast when it is finished!

I will leave the pedal alone, i dont want it getting stuck.

the bracket itself took 7 hours, give or take 2. because i had no idea of the positioning of the pedal, so it was trial and error. now that i have a basic idea, should be quicker.

This swap is slow, because im collecting parts as i go. If i break one barrier, i move on to the next. remember, i had no idea the engine would fit in the bay, it would have been a 2700$ loss for me... ( there are cheaper, but not with less than 25K miles and complete with all accessories).

this is the bracket on the car...

DSCN1377


of course had to make sure that

DSCN1376


i used long bolts, and thread locker... Do not want to get loose on me.. Same went for the pedal...

DSCN1378


and next task, will be to find out if these go in with no problem...

DSCN1379


hate to take a loss on them.....

Man, I hope they fit! It looks crazy tight already!
Good vibes, hope they fit

The real question, how does the rear fit? tongue.gif

2001 Miata LS 5-speed
Won't you throw automatic transmission DTC's with the PCM for the 2GR, or did your 2GR come from a manual car?

2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
yes he will, the only car with a 2GR thats a manual is the Lotus Evora. Most of the AT codes can be defeated except one. The MR2 guys have been fighting it for years.

And that puts the engine in limp too, doesn't it?

2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
to answer the questions...

1. I know how the rears fit... wont say for now..

2. Yes i will throw a code..

3. it wont put the engine on limp, otherwise i would not have done swap.. (mr2 guys have all of it covered.)

I remember a fellow with a MZ in their MR2 that was doing funky things with an auto PCM, pulling timing at certain RPM's and I think it was related to the codes thrown.

At some point wouldn't it just be easier to use a standalone than to bother with the factory ECU?

2 points.

1. yes if you live in an area that does not do obd2 checks.

2. It has not been fully developed yet. So i would rather be safe for now, than sorry, than to blow an engine. I cant tune, and wont be paying hundreds to get it tuned, nor do i have a dyno near.

Easier? No. Better? Yes. Cheaper? Hell naw.

For this build the very least you should get is a Sport 1000 from Haltech. That's over $1200 right there.

Make the stocker work for now and you could maybe later on use a standalone as a fuel/ignition controller for tuning purposes. A cheaper one, like a Megasquirt.

Just move further south. tongue.gif

2001 Miata LS 5-speed
But you won't pass OBD2 checks with a trans code stored...

2000 Celica GTS 'slowest gts evar'1998 Mazda 626 FS-DE/CD4-E
well unless you guys chime in (i can pm my paypal), lol, no standalone guys sorry. And as far as the obd codes, working on a solution, possible to get around that transmission codes.

However i dont live in an obd2 check area, so no real worry for the moment.

I wont be spending money on tunes and dynos. period. but thanks for the encouragement.

so far so much money invested on this, that not really looking to invest more than i need to..

Just think though, you'll have the only one that we know of. That's exciting. redface.gif

2001 Miata LS 5-speed
well im going to post few pics here and there. obstacles to overcome....

DSCN1391


cut to this size to get more clearance

DSCN1392


then see this..

DSCN1396


bend to make this..

DSCN1397


unfortunately that tab, holds the power steering lines and will have to be relocated. But to answer everyones questions, smaller bolt is no longer in the way ...

DSCN1398


it does fit, and i have headers... (740 usd from Gouky)

couple of other things that i have to work... there is no space if you use the regular fans..

no chance for the a/c lines, and will have to use a custom combo...

DSCN1388


cant use the alternator with the stock fans and shrouds. need to get custom or creative..

DSCN1387


DSCN1390


relocate the dipstick, move it a little to the side

DSCN1383


clearance with oil cooler. but this one is ok...

DSCN1384


lower radiator hose, will probably have to come from the highlander, or a hybrid mix of both... because the celica hose interferes, so i need to get a hose union or something to mix em together

DSCN1394


upper radiator hose needs to be cut just a tad, careful where u cut it, so that it does not rub with engine..

DSCN1386


relocate the fusebox, you almost most have to it would be in the way of the hose..

DSCN1389


relocate power steering bracket for the reservoir

DSCN1393


then tackle the axle carrier bracket, going to have to weld something or go custom

DSCN1400


DSCN1399


as it is, the engine is 1 inch lower than the beams, or 3sge... so long plastic covers...... or maybe they will fit, only future will tell....

DSCN1395



so if this is not a clear description of what needs to be done to the car, i dont know what is...

Is the PS axle going to fit with the header there? It might be the angle of the picture, but it looks like a pretty close call.. Props on all the work though, absolutely amazing.

it fits, it is proven by guoky... that was never an issue. but i know the pic looks bad...

You must have the patience of a saint, I'd have set everything on fire by now.

My recommendation is to take out that double core radiator, keep the stock fans and a stock radiator. A good quality replacement.

Since you're going N/A you won't need a huge radiator at all, especially since you're probably using a GT-4 hood to clear the engine, right? The stock radiator is good enough for a 3S-GTE GT-4, should be good enough for a 2GR N/A. I'm actually considering removing mine and replacing it with a stock one, since I never really saw any huge improvements on cooling, my temperature problems turned out to be tuning related.
