Alternative engine

[Dazza]

I have reciently got my first Surf, got it cheap with a knocking engine. I'm an engineer / fabricator by trade so was quite happy to change the engine. That was till I found this forum, seems that these are prone to problems. So I am thinking of converting to another engine, have done it to several landys. It's all a bit compact in there and I wondered if any of you have any experiance in conversions and know what fits?

I've now stripped the motor it has big ends gone bores shagged turbo unusable, heads ok!

TonyN is doing a conversion to a 2.4 as far as i know so watch this space for tips

Whats the 2.4 from? I was thinking transit lump but the 3ltr + would be better, I do like perkins.

We are actually replacing the 2.4 TD (with knackered head etc) with a Rover V8, and a BW35. We'll then convert it to LPG. Tony a similar swap on his old Hilux Pickup and it worked well.

The M series Supra engines fit quite easily with their own clutches, radiators and cooling sytems. The only slight problems are that the rear engine mounting bracket is a bit far back so you have to either weld over the mounting holes and redrill them or cut the bracket and weld in a 10mm spacer. The oil pan on the 5M and 6M Supras is at the front which is no good. There are other cars like the older Camry that have the right oil pan but they're rare here and you'll probably have to buy the MK111 Supra pan and oil pick up from Toyota (£160)

The M Series engines are all getting really old now and they have serious corrosion and cylinder head problems so you'd have to find a good one from an import. I like the 5M engine better than the later ones coz it looks like it was designed to be in a Surf engine bay and it has lots of ribbed alloy castings to polish:-) Although it's a 2 valve per cylinder engine its capable of much higher flow rates than the later 4 valve engines but tuning it costs HUGE amounts of money and the parts are very difficult to find too.

I wouldnt bother fitting either of the Toyota V6 engines coz they arent as powerful as a standard non turbo 5M

I like the idea of fitting a newish Lexus engine like the IFZ-FE (4500cc straight six similar to a 7MGTE) or a 1UZ-FE (4000cc V8) but all I know about them is that the V8 fits straight onto an R series gearbox. WHatever you get make sure you get the wiring and ECU as well coz otherwise you'll never get it to run on your own.

One small thing which might prove very annoying is that the R150 gearbox is designed for diesel engines and it has a really wide gap between 1ST and 2ND gears which sort of spoils the performance of petrol conversions. If you can find one the R151 gearbox from a V6 Surf or Prado would be much better.
