Cressida 7M into SFA

After doing lots of research, I have decided to replace my SFA's 4Y with 7M-GE from a Cressida instead of a 1UZ-VVTI with a 5 speed autobox.

My reasons:
I have always preferred a manufacturers OEM ECU over an aftermarket ECU. (I don't want to go into this too deeply, but I got burned by a MR Turbo unit once, mainly because I misunderstood some of the settings. I'm not foul mouthing any aftermarket part, I just prefer OEM)
For the above mentioned reason, I looked at front clips from engines and more, I saw some of the other resellers that sells these VVTI engines with OEM ECU's that can start, and I was very impressed by it all.
I was also advised to use the VVTI with OEM ECU but with the 4speed auto box running spitronics, but I didn't like the idea (see above reason).
I also need an adaptor to mate the SFA transfer case to the Auto box. The transfer box wouldn't move too far back if I used the 4 speed box, but the 5speed box is too long, and moves the transfer box so far back that you'll need to alter the propshafts. (See comment above about using OEM)

The cost factor also contributed to my decision.

So I decided on the 7M.
Their parts are still available.
The engine is reliable as long as it doesn't overheat or runs low on oil.
The headgasket problem can be avoided.
I was lucky enough to get a deregistered whole Cressida in a fair condition for R15000.



I'm using as much as possible from the Cressida including the ECU, but needs to source some parts:
Bellhousing and Flywheel (since the car is an automatic)
Clutch
Radiator and electric fan

Work that needs done:
Torque the head to 97 Nm. The gasket is of a high quality.
Do some repairs and modifications to the Cressida harness to mate it to the SFA's existing wiring. Also add a "Check engine" light
Alter the engine mountings to fit the mountings on the chassis.
Do a 25mm body lift.
Move the aircon radiator somewhere else. (I'm considering putting a scoop on the bonnet and fasten the condensor to the inside of the bonnet. There's enough space if a 25mm lift is done, and the pipes will make it.)
(Finally) Fit the long range tank that I bought a year ago and work out something to make an electric pump use the long range as a primary and the existing tank as a reserve.
Move the battery to the left hand side as the Cressida airflow box goes where the battery currently is.



Finding a bellhousing was easy, but the price was a problem. Gemini doesn't have stock, and people wants new prices for their secondhand parts. (Second hand at between R3000 and R3500 for one that has never been test fitted)
The Flywheel was a bit of an issue. The 4Y flywheel is the closest fit, but some holes needs to be moved.
I eventually realized that the 2.8i Cressida uses the 5M engine which is much similar to the 7M.
I bought a 5M flywheel and bellhousing for R1900. It's a perfect fit. The 4Y's fork works, and I used a KZ-TE slave cylinder.


I will add pictures as i go along.

The cooling system on those conversions has always been the biggest challenge. Good luck!

Ou maat ek hoop al is goed, want ek wil dit ook oorweeg in my bakkie, wil net weet waar het jy engine gekry en wat was die prys, dan wat gaan die hele storie jou uit jou sak ruk, doen jy dit self of iemand.
Dankie
Charles

Keep and use the auto box, mate it to the transfer case, we also have a 7MGE fitted to one of our Hilux's, does the auto box that you have, does it have low range auto lock in it?

Hi maat

Maak seker van jou verkoeling en jou engine mountings !!! As die engine mountings nie reg is nie gaan jy jou engine teen die radiator druk

Watter engine mounting gebruik julle?
Weet julle of die 3,0 liter 5L se flywheel en clutch op 7M sal pas

Hi

Simoan:
I am not comfortable with the custom adapter needed to attack the transfer case to the auto box, although I would love the comfort of the automatic.
I will check the model number of the autobox to see if it has a low range lockup function, although I believe that it does in fact have. I will probably sell it if you're interested.

Richard:
Ek gaan custom mounting brackets vir die enjin bou sodat die enjin so ver moontlik terug kan gaan. Ek gaan die standaard 4Y mountings gebruik wat op die chassis pas. As dit nie hou nie sal ek kyk na 5L mountings. Ek gaan 'n 3RZ (of 2.7 bullnose) se radiator in sit met 2 corsa lite fans. (viewtopic.php?f=3&t=29614" onclick="window.open(this.href);return false;) (Dankie Kaspaas!)

Charles:
Sien kommentaar aan Richard oor die mountings.
Ek aanvaar jy praat 3.0 diesel 5L? Ek het 'n 2.8 Cressida se flywheel en clutch gebruik met 'n KZ-TE slave cylinder. Die naaste ander flywheel match is die 4Y. As ek reg onthou moet jy 2 gate laat verander. Hou in gedagte dat jou starter se rat nie noodwendig lekker op 'n ander ring gear gaan pas nie.
Ek glo nie die 5L gaan werk nie, alhoewel die swaarder flywheel awesome sal wees vir 4x4.

Hi Jacques
Ek oorweeg ook om 7M in my hilux te bou, wil net graag by jou hoor hoekom gaan jy jou bakkie met 25mm lig, en het jy al iets uitgevind omtrent bellhousing, as jy iets hoor ek is ook opsoek maar is nie seker watter gearbox in my bakkie is nie, hoe weet ek vir watter bellhousing om te vra, het jy al Gilo Engineering probeer vir bellhousing.As jy kan sit fotos op van projekt.
Sterkte
Charles

Ek lig die bakkie grootliks omdat ek die aircon radiator aan die bonnet wil vas maak..
Dit sal ook bietjie help wanneer ek grooter bande op sit. en ek gaan 'n ekstra tank onder in sit. as ek 25 mm daar kan gebruik is dit net 'n score.

Die 2.8 Cressida se bellhousing pas net so tussen die hilux rat kas en 7M enjin. Ek het een van 'n scrapyard in Durban gekoop.
Die persoon by Gilo was glad nie lus om my te help nie. "Ons maak nie die bellhousings nie omdat die 'n standaard Toyota part is. Totsiens."

Ek het 'n paar foto's, maar vir ek kry nie die foto's vanaf photobucket aan die forum geattach nie. dit kla oor die foto's se grootte. Ek moet die foto's nog resize.

you guys just have to remember that the heater hoses run behind the engine cylinder head and thus there is not much space to bring the engine back, I will take a few pics of my 7mge engine in my Hilux and show you

In order to get the clearance right at the back of the motor it would be wise to do a body lift !

Ek het die 2.4 diesel radiator hys redelik groot en veronderstel om die van koud genoeg te hou maar kon dit nognie toets nie omrede hy nou staan
Die ebgine het in die radiator vasgedruk en is nou besig om daai probleem uit te sort

Ek gaan kyk of die 3.0 D4D mountings gan pas anders gan ek weer die 2.2 mountings gebruik ! Onthou net die yster cups wat oor die mounting gaan sy doel is daar dat die engine nie vorentoe beweeg nie

Ja, die diesel radiator is groot. Die BMW radiators pas beter, maar die 2.7 bullnose radiator is lekker dun. jy moet in elkgeval van die plaat voor weg sny en weer versterk.

Hi Jacques
Ek het ook die 7m ingebou in my SFA.
Het jy die diff standaard gehou met die engine conversion?
My diff moet oorgedoen word.
Verder moet ek my bladvere ook vervang.
Enige voorstelle?

How did your conversion go?

Nie so goed nie. Die enjin hang nou al meer as 'n jaar aan die balke as gevolg van 'n gebrek aan tyd, en verkeerde enjin mounting brackets.

Ek gebruik nog die standaard diff, en die bladvere is ook standaard. Ons sal maar plan maak as dit 'n probleem veroorsaak.
