Cheers! So i kinda been searching around for a locally, good conditions engine to swap my Celica. And today i found a what i think is a deal, It's a MR2 91' 2nd Gen 3S-GTE USDM 71k Stock Everything 200HP Stock Compression is 150plus cold/ 180 plus warm on all cylinders ECU and uncut harness Stock Intercooler, blow off valve and piping. NO TURBO INCLUDED (He was running a bigger turbo TD06 with a rom tune and 550cc injectors, and hes swaping a 3gen JDM 3sgte, so he's taking the bigger turbo) Engine still on the MR2, he haves started disconnecting everything, to begin removing, Those engines use a CT26, same as a 7MGTE Supra engine, i have found some good deals on ebay on that turbo,new, so if i get the turbo, i'm cherry http://www.ebay.com/itm/86-87-88-89...ruck_Parts_Accessories&vxp=mtr#ht_4854wt_1163 Pics Of The Engine: Price Is 800 Or Best Offer, i pick it up. So i have a few ? Does this is a direct fit in my Celica? What else apart the turbo and ecu, harness do i need? Fit my 5speed tranny right?
Yes and no. Using a motor from an MR2 is more of a pain IMO. Alot of your brackets are going to be wrong. Plumbing is going to be different, wiring will still need to be extended, and as far as the turbo goes...theres alot of "rebuilt" ones out there that are more likely junk. Doing a swap is more involved that what it seems. Not to be discouraging, but know what you are getting into.
jum.. yeah i kinda knew it wasn't going to be that easy :/ if i still decide, what can i do about the brackets and plumbing? And Thanks for your IMO, really helps Also, have this have been done? a swap form a MR2 into a Celica?
many many swaps have been done from mr2 to the celica and the other way around. it's possible but you're going to have to do a lot of research, for example your alternator is in a different place, trans won't work from mr2 unless you mod it to fit (the shifter linkage is pointing the wrong way), you need to use power steering from your celica...all sorts of stuff
It's been done plenty - I have one for sale here Basically you got to swap everything over but the headers, inlet, block & head. Even the downpipe is way different so you'd have to make one So if you already have all the parts and a good gearbox it's not a problem except for the harness It's expensive to do properly but worthwile depends on what your expectations are. I'd opt for a BEAMS over this and the result would be similar with a lot less work & money The reason I'm selling my MR2 GTE is the parts - there just isn't parts for these motors and most skip them and fit the ST205 or ST215 motor with upgraded rods, sump, lower CR pistons, head, cams, buckets as standard For a gen2 GTE you need to swap the harness, so might as well just swap to something more common/available?
I'm buying it in a couple of weeks, downpipe, can i just buy a mr2 3sgte one? or a a custom made one? can i still use my fuel pump, radiator, power steering etc? with the tranny, do i have to modify the linkage, buy an mr2 one or what? Thanks guys, and sorry for me keep asking :/ fist swap ever!
You'd have to get a GT4 downpipe or mod the MR2 pipe and change your radiator The MR2 box is useless to you, don't waste money on it or sell it quick, ie- To make the GTE box work you'd need to buy the axles and a GT4 box + axles to strip for spares. Youd have to swap the GT4 mounts and selector mechanism over and block the hole for the MR2 selector with a plug plus swap the speedo drive I have used a MR2 box to convert a GT4 box to FWD on my thread and the selectors I have for sale in the parts section but I don't have the linkages, cable brackets or shafts spare. Youd need to use Hybrid MR2 inner + 165 outer shafts, it's a pita to do I'm not sure if the V6 Camry/Solara shafts fit our cars, maybe Mafix can clear that up? Looking at the pics I'd say you need a Alu radiator, IC & piping too - it's not a cheap as you think
Thanks Stig! You cleared my doubts! I think is better for me to save those 800+ and save for a CELICA swap, or just fix the 500HP+ 3sfe :| i think is not worth it
A lot depends on whether you have or are able to find the parts - cheap If you ditch the box it's worth a bit of money, it's regarded as one of the strongest FWD (style) boxes ever made and the fact it can be used as RWD/FWD is a bonus - On the Lotus and Mazda sites I've seen them sell for $1200-$2000, even the companies that convert these boxes just don't have stock. The LSD inside isn't as good as a/m, but considering the a/m are around $1000ea? The lotus guys will buy them and then spend another $1000 on shafts and bellhousing, mounts etc, plus $1000-2000 on a rebuild - to bolt to a 1800cc, a $5K box just doesn't make sense to me but it's the rage with those guys! If you tried to pre-sell it - it may/may not make your conversion a lot cheaper The way to convert is to study the options carefully and discuss them, decide what you want and then slowly buy all the parts you need cheap, till you are ready to swap. It's frustrating and time consuming - but SOO rewarding when it all comes together
some of the brackets from the 3sfe motor will swap over, like the power steering bracket. the 3sfe gearbox iirc has the starter motor on the gearbox side not under the exh manifold correct? (well the sv21 3sfe did) so you could for a cheap way just use that gearbox with a gen2 3sge flywheel and clutch. i haven't seen any difference between celica and mr2 down pipes from the same gen motor, the only major different one is the one from the gen1 3sgte which had the single entry ct26 like the 7mgte. but that gen2 mr2 motor will have the turbo manifold for the twin-entry ct26. you'd need the gen2 celica water outlet neck, and thermostat housing/neck you'd possibly need to fiddle with to have the temp sensor etc fitted on it.
Im sure the GTE flywheel will work too, I'm using a gen1 GTE flywheel with a S53 box The MR2 exhaust has a different shape, ours is near straight Either use a gen1 waterpump or find a GE gen2 outlet which has the sensor fitting Interesting anecdote - I noted that the badge on the MR2 GTE inlet says ceramic turbo while the GT4 doesn't. The MR2 club guys tell me all the JDM MR2 GTE's are ceramic where I think only the RC had it. Depending on who you talk to the ceramic version is either better or a piece of .....
gen1 3sgte has the same pcd where it bolts to the crank as the 5sfe, it's not compatible with the gen2+ crank. isn't he going turbo, so those NA haeders etc aren't what he's looking at, the dump/down pipe from the turbo is the same mr2/gt4. obv he'll have to connect his stock exh up to the turbo dump pipe as with any turbo conv. he has to use the gen2 gte water pump and housing as it has the oultet for the water-oil cooler off the pump housing. the thermostat housing does have a fitting for a temp sensor but the neck itself is shorter, i don't know if it's too short for the bottom rad hose to reach without fouling on the ac compressor. all JDM mr2's/gt4 had ceramic exh wheels(gen2/3) except the GRPA/carlos sainz/RC 185 GRPA/WRC205 and all ADM gt4's (st185/205) had the steel wheel turbos.
Correct, I'm using the gen1 + FE box. A gen2 GTE crank/flywheel/clutch should also fit? Pic was just to show the twists in the pipe, I'm not sure where the GTE downpipe ends I forgot about the cooler pipe, would need a longer hose or mod the GE housing/gen1 housing Interesting that the labels on the intakes don't say that?
you can use the gen2 3sgte flywheel and clutch cover but not the disc itself if you keep the s54 box as the spline on the s54 bo is smaller than the E15 box. the turbo down/dump pipe ends a bit in front of the sump, and you'll need to get an exhaust shop to link it up to the rest of the system. on the gt4 the "ceramic power" is written on the ATA intercooler. the GRPA/CS with the WTA intercoolers don't say anything about it.
Yes, I just used a S54 clutch plate with the GTE flywheel/p/plate, it's a few mm smaller but no problems after 2yrs of abuse. I havent checked but I think the GE/FE p/plate will bolt to the GTE flywheel Yes, exhaust mods are required. New exhaust is required as the FE has a meanie little pipe AAH, never seen that - so few of those ATA's around. So the MR2 guys aren't as clued as I thought!
What the mr2 guts said about all jdm mr2s being ceramic is correct. The difference in spool between ceramic/steel is neglidgable, but the steel is stronger. The adm and grpA inducers are also larger by the ones ive had. I think they may have used the 7mgte comp wheel for the steel wheel varieties. the part numbers are diff for the runofthe mill jdm gt4 turbo and the grpA/rc/various wide body versions
