If I want to put a 31 V8 into my 32, what had to be done?
Next, has anyone ever swapped the V8 out and put a turbo 6 into the 32? I know there would need to be brackets made up for the pump etc. but is it too big a job to do, as the 6 is much more economical and goes better for cheaper? Cheers John |

As far as i know, the V8 blocks are the same, you would just need to swap the PS/suspension pump, alternator, timing belt cover, harmonic balancer and perhaps the AC pump over as well from the old engine into the new engine.
If you put a 6 in it, you would need to find some way of mounting your suspension pump, or changing the suspension for coil overs perhaps. |

Hi Rob, the reason for having a 32 is the suspension. How do you find your 32? Just looking at the best long term solution to economy and power. Thanks, John |

'31 engine can be done, but big job. Upper sump is different as are the front plates on the engine. It's basically a strip back to a long block and change the parts over.
Turbo six will suck as it loses the low down torque where the '32 needs it. Will have a bit more top end, but will really struggle off the line.
6 will also need major fab work to make everything work as well as possibly major electrical work.
For the same sorta cost you could supercharge the V8. |

Definitely worth supercharging the stock V8 over anything. |

Thanks Dan,
that clears the issue about the 6 then.
I have 250+Ks on this baby and so am thinking ahead before I go and spend up on all the necessities to get the suspension in top shape.
If I had a low klms 31 V8 it would just mean putting the hours in, right? No big deal, just time. What gaskets would I need and where best to get them?
How about the ECU on a 31, will it work on a 32 or does the 32 have its own ecu and if so are the caps that fail the same ones as the 31? They must about be due by now too?
Thanks for the help and for the suggestion to supercharge Haydn but the cost of supercharging is over the top for me. I meditate about a rear mount turbo that I would make up myself, off guides on the net. They can be very inexpensive as long as you don't want to go racing. I just want some more usable horses at the lowest possible rate. Hope to get out of it for under $1000 with a second hand unit and all the work myself and waiting for good deals on blow off valve and wastegate.
Need to get a little mig and do the pipework myself with the right turbo for rear mount, which uses a smaller housing than would a front mount. There is no need for an intercooler as the system self cools under the car as long as I run it at about 6psi. No need for another ECU with this too.
I will need to learn more but feel that I am slowly getting hold of it. There are plenty of people saying they have made it work despite the early skepticism.
Thanks again and always interested in the opinions of those who have been there, done that.
Cheers John |

Use this link to navigate through the parts to get the part # of the gaskets you want to replace:

Here is a link to the engine overhaul gasket kit:

Ummm not sure how to order them after this. I think you need to ring toyota and get this ordered from japan. Prices are also on the links.
Not sure if this is helpful but i use it to find part numbers all the time  |

swapping a V8 and replacing it with a turbo 6 in a 32 ????
that"s almost as crazy as taking out a 351 from a XYGT and putTing in a turbo 6 LOL |

Try amayama.com or driftmotion for parts, also rock auto in the states is good for a lot of stuff, but you won't get any '32 stuff there (jdm specific)
32 ecu is different, but only marginally. It has a tiny bit more timing down low to help it off the line, and also has a rudimentary form of stability control that works through the 4-ws and trc systems. 31 ecu will work just fine.
Some gaskets, some FIPG. toyodiy.com for parts catalogues and find the stuff there.
Rear mount turbo is good in theory, but will have significant lag (even a small turbo) that will defeat the purpose of the exercise. A shot of nos off the line would help, but then you need the bottle filled when it runs out.
Caps are the same, I think and definately worth doing.
Be careful, Toyota •••••• up. Under the ashtray inside the car is the main accellerometer, super sensitive bit of gear and about 7k for a new one from toyota. The issues is that the plug on this is exactly the same as the cigarette lighter plug, and +12v will let the smoke out before you can say "where the •••• did that smoke come from".
If you're clever and patient then supercharging could be done for a couple of k. |

Thanks Haydn for those numbers.
Dan, thanks for the help. What is an accellerometer? I had the EMV out and fixed the caps on it with Tom Richards in NSW. The cigarette lighter has a blue connector plug, is there another blue plug there the same size, that was a big mistake if there is!!! Do you just know that the smoke will come out or did you plug it wrong one day?
I saw an M90 on Ebay for $675 brand new. Should I be buying this? The problem as far as I understand is that the fitting costs heaps, getting stuff made up, like a new inlet manifold etc, even without someone else's labour. How can I do it for $2000? Would that price on the M90 allow me to come in at that price?

Depends on what other stuff you can find cheap or pre-loved and how handy you are. M90 is also fitted to S/Charged v6 commodores so easy to find.
The accellerometer basically controls the active system. It's what lets an active do what an active does. (along with the rest of the stuff, of course)
I can't remember if it's also blue, but it's the exact same shape plug.
It happened to my spare parts car before it became my spare parts car. (I didn't do it) |

Ok, I will put up a post sometime asking what I actually need to do the deal with a supercharger. It will be when I want to actually make a move on starting a go faster project. I have just fitted a sequencial LPG injection to my 31 in Melbourne and will drive back to Brisbane in another week and see what economy I get. It cost me $224 and 180 litres to get here from Caboolture, so hoping to go home for about $120 or less with a fully loaded car, will see how I go? Cheers John |

Maybe look at fitting a 97 V8? Different ECU, but better power and fuel economy.
I got 10.785 km/litre based on the speedo while returning from Victoria recently. Based on the GPS the figure was reduced to 10.367 km/litre - still better than what I would expect from either a TT or an early V8. |

Hi Peter, That is good economy hey, I got 9.5 klms/ltr from Brisbane to Melbourne on my trip in my '91 31 but I used XFT, which improved my economy about 5% from before. The XFT is supposed to increase economy with each tankful but now I will not be using petrol much in the 31 now as I just had sequential LPG injection installed. This will improve my Klms/litre too as well as the price of LPG being half of 98 and it has maybe 110 octane, so more power too.
That is all in my 31 but I am looking to the future of my 32 with the thread that I started, so how much do you think I can get a late model V8 for, with its better O2 sensors that give greater economy? The internals of the later models not so good, even though lighter, which probably contribute to the better economy too? With my thinking of going aspirated the stronger motor should be better?
Thanks for your input.
Cheers John |

Yeah, I wouldn't add forced induction to a 97 motor, unless you were going to change the con rods etc.
I always thought the choice was economy or power!
I haven't felt the need to get more from the 97, it's pretty lively anyway and I don't do track days with it. |

I guess that is the magic formula if you can get the both, hey. The LPG with the right injectors (prins type) you can get both economy and power together and keep up with the needed output for forced induction too if you want. The old solenoid type injectors can't give this kind of result. I will let you know how it goes after the trip back. Hope I am right . Cheers John |

86/8..97 Soarers have sequential injection as std also the 4 o2 sensors must help,shame about the con rods.

If you have a pre 1993 UZZ32 and want to fit a 97 engine in it stay with you old engine harness , there are a lot of things that will be different , been there and done that with my 1994 .I would think the 97 non VVTI would have few more things different to my 94 also .
I really think if you are going to fit a blower or turbo stay with a pre 93 engine so you don't need to change the con rods and all the wiring will be the same .
Gaskets / thermostat housing I think is o-ring ,a few o-rings on the front of the engine there are no gaskets to change if your taking the front engine plate off the 32 , sump I use 3 Bond , its the same as the Toyota sealer ,Dan said the upper sump is different , that i'm not sure about and i am sure he's right , A/C is the same but the High and low pressure pipe configuration is different , not hard to change .
If you are going to go a blower just go for a Whipple or the Eaton TVS first up , I had an M90 , it was good but no where near as good as the Whipple . Guys are making around 300Kw's on stock engines but with a good ECU , bigger injectors and sometimes water/meth injection just to help with the air charge so you can run some timing .
If your looking for a Whipple setup I have my complete deal for sale less the manifold . |

thanks Mario, Good helpful advise. I am a bit off doing anything at this point but will keep all this on file. Cheers John
Ps. Economy on my new LPG set up was not as good as I expected, so will look at the tuning this week. |

The rear housing on the '32 aircon compressor is different.
If you fit a '31 compressor straight on you will eventually break the oil pump for the hyd fan. |

Mario, you said "A/C is the same but the High and low pressure pipe configuration is different , not hard to change".
Dan said that you would break the oil pump for the hyd fan.
If you were to change the A/c comp to a 31 how would you change the high low pressure configeration?

Hi John, I'm not sure with what Dan has said but maybe right .
What i did years ago was I had a very good UZZ32 body without any electrics , I took everything out of the 32 , Chassis front and rear ,all the 4WS parts , brake booster, all the suspension lines and piping, all the suspension , all the brakes and lines , all the electrics , every computer and all the wiring until I ended up with two empty shells , then put all the parts out of a UZZ31 I had that had been in a stack into the 32 Body , the only thing i didn't change was the A/C lines and heater box inside the car because there were both 1991 models.
I found that the UZZ32 A/C hoses/Lines where they go into the AC compressor were different ,the problem was the header plate if i can call it that where the hoses fitted to the compressor where different and you couldn't get the pips back onto the compressor . I took the plate off the 31 compressor and fitted the plate from the 32 engines AC compressor , the hoses went straight on without any problems, I didn't change the compressors over from a 31 to a 32 and that what i think Dan is taking about . Just changed the top plate and its was still going 12 months after i got it back on the road .
There are so many things different in these car and a lot of it is in the electrics , all looks the same from the outside but its a big can of worms if you get it wrong . |
