Hello All
Happy new year
Anyone retrofitted another motor into to 4cyl Magnas TN-TP
Overseas they had a 2 litre belt driven cam motor and also in NZ they had the 3.0l V6 motor as an option they called them Mitsubishi V3000 instead of magnas.
Belt driven motors would have to be better than wearing the cam chains out all the time in the 2.6's.
Cheers vee

4G63T from an Evo 1-3 seems to be popular for first gens.

tr motor, i was lucky to get a real good one (20,000 off a professional reco) for free but they are a world better as they have a different timing chain tensioner and roller rockers. also have better flowing heads apparently and kidney shaped bores. all together they are much better then the earlier motors. ive got one in my tp and she is a beast. best thing is no engineer's cert needed as you use all original mounts ect.

So did you put in the TR injection system and computer as i know they squeezed a few more kilowatts out of the TR with higher injection pressure and some other changes. If not basically the motors are not that different. I think you can update the earlier motors with TR oil pumps etc with the better cam chain adjuster etc. TR motor should be a tad more economical if you have the injection system updated as well.
If you did change the injection as well did you have any snags with different wiring looms etc?? Cheers

Better motor and ECU is the TS 4g54. As if it has the M9 head they it will have higher compression and ECU has a better tune as well :)

welcome to the club another gen1 wagon
the tr ecu will need the wire loom as well to much work involved
best way to get more go is a 5speed conversion
shaune95 tried to fit a tr tb and injectors to a gen1 it didn,t work out

HAHA yer it dosent like the change in the pendlum and timing is a pain in the but, found out the isc motor had shat it self and the ecu might be stuffed as well.

tbh from my experience the first gen efi is better then second gen anyway. mine runs as sweet as a nut with just a home injector clean job using throttle body cleaner and general throttle body clean.
she has a great throaty sound too. and ill agree the 5 speed makes soo much difference to speed its unbelievable. ide highly recommend both if you want a little bit of a cheap project and much more speed and economy. i do better then 11km per litre (9 per 100) on city and about 13 / 14 highway (thats app 7 per 100 on highway). dont know how i get such good economy, must be a combination of first gen efi and 2nd gen motor. and i certainly dont drive it easy either.

Ok thanks for the info have found a manual conversion for $250 only done 124K the car is mint and should not be at the wreckers.
The better gear ratios on the manuals give better performance. What sort of revs does the manual do at 100k or 120k in 5th.
My auto wagon does 120km/h at 3000rpm in overdrive and torque converter locked up. 2750ish 100km/h 4th.
1st Gen EFI puts out 93Kw
2nd Gen EFI gets 98Kw or 103Kw with premium unleaded. (all carby models 85Kw)
V6 have 125Kw.

it should sit at around 2000 at the 110 mark. thats providing its a tn/tp box as the tm has different ratios. mine sits at about 1500 at eighty. great thing about these cars is you can either be in 2nd or 5th at 80 depending on how much you flog it. i often go from 2nd or 3rd to 5th anyway. 4th is overdrive and 5th is a higher overdrive so they dont rev too hard in the top gears and still pull well.
make sure you get the lay shaft and mount that bolts to the back of the block. its the small extension that has the left hand drive shaft slip into it. the drive shafts are the same but the bracket is not. also get all the mounts, the auto ones fit but are far from decent.
you can get away without changing the engine loom but ide recommend changing it as its easier then bypassing everything. the efi relay box under the dash also needed to be changed on mine. maybe a good idea to grab ecu too tho i didnt change mine. only thing you need electrically for the box is the reverse light connector and about a foot of cable off it. its easy to join in under the air intake. ill go and look at the wire colours to make it easy.

i did it in about 10 hours work, but i have the luxuries of a block and tackle and plenty of tools, drills, jacks ect ect. all depends on what you have to work with but it is basically strait forward.

any other questions dont hesitate to ask.

What ever did happen to the Red 1st Gen Wagon from many years ago with the 4G63T?

Goofed up Jay on the last post did a run on the highway yesty and auto actually sits on 2400rpm at 100k and not 2750 i said from memory.
Yup will grab the rest of the gear. ALso have a engine hoist and engine stand etc.
Last year did a Nissan Maxima conversion to manual and it was easier to take the auto out with three scissor jacks under it as only had around
5mm of spare room to slide it down and out so with three scissor jacks i could finely adjust it in three dimensions to remove. There was a tad more room to put the manual in but not much. Very tight indeed.Wiring is pretty simple most of the time. Sometimes the older EFI auto ECU's are ok to use in manuals the nissan did not throw engine check light or anything. I guess you noticed a nice increase in range going from auto to manual on a long trip if the economy is so much better. Vee
P.s I've had several generation ones and have converted two of them from carby to EFI and that alone makes a big difference in power etc.ALso changed the trannys in doing so etc to make use of the better ratios/ reliability in the later trans and get some benefit from the better power with EFI etc.

just did a trip down to magnaman89's witch is about 150km's and she did it in the wink of an eye. it sits at 2500 revs at 110km and 2000 in 5th at 80km. i got 470k's out of 47 liters exactly so thats good economy for a full sized car, but i have had better in her. i have my suspicions the clutch slips a bit up hills at high speed so i lashed out and bought the works, new clutch and pressure plate, slave and master cylinders for around $330 on ebay. with that she should see another 5 years and at least 100,000ks before anything major lol.

ive never had an carby but everyone reckons they are crap. i gave mine a few squirts tonight and she dam well moves for a little rice burner in a big car!

i love having a shed with 6 inch c channel trusses, makes lifting the engines out of cars a dream lol

the 5 speeds have great ratios because they are well suited to the wide mid to hight end torque of the 2.6's. mine does 1 - 100 in under 10 seconds and thats almost totally stock, apart from the g2 motor lol. personally i really wouldn't bother with second gen efi. never seems to run smooth and only a pain in the backside to wire in. as you know gen one stuff is a few plugs lol

good luck, if i think of anything else ill post it up here.

Would that happen to be the one i saw on ebay just before?
