As many of you know I have been at the forefront of the mission to find more power for our trucks. Various ideas from fitting V8's to the V6 swap have all been considered. I've received a fair bit of abuse for this from the other forum by people saying it's pointless, just accept the L200 is a slow truck. Bla bla bla bla bla bla etc etc etc......... Without deviating from the point I'm about to make, V8's and V6's went by the way side for personal reasons. Veg being one of them. Although I will say I know they can both be done. The Mitsi V6 especially should be a 'simple' plug and play conversion and good for over 300Bhp. But back to the point in hand, the 4D56...... maybe because of my attitude to things, being fairly new to automotive engineering but having a degree in engineering anyway, I was always taught to find a way. Not to think about what can't be done but to expand on what CAN be done. This is a principle ALL engineers should live by.

So, I've built this up somewhat, but with good reason trust me...........


I Found a guy on Pocuk who was determined to prove that any engine, including the 4D56 in his Pajero could be tuned. Knowing his way around a workshop and an engine, he started with custom inlet and exhaust manifolds. Soon came bigger turbo, custom hi lift cam, balanced rods and pistons (which were also machined for clearance due to the cam), larger valves, custom valve springs and a port match. Flowed the injectors and fitted a whopping great intercooler where his grill used to be.

He got it up to 200 Bhp ( but was limited by the pump, so was running slightly lean. His Paj does not have the ECU and pump that we have on our trucks. He did such a good job of cooling the engine that Inlet and exhaust temps actually dropped compared to a standard engine. The next thing on his list was to fit an ECU and electronic controlled pump like we have so that he could deliver more fuel. Enough fuel. He was also considering common rail'ing it as on the latter engines, again for more mapping scope.

Interestingly he never had a single issue with the aluminium head. His arguments here simply being that they don't have 'weak' heads as everyone argues. They have over heating issues. Which in turn causes gaskets and heads to go. However, agree with him or not, he proved a point with his temps. He also argues "what cars don't have ally heads these days?" (note here that even an LS1 has ally heads) He did have a couple of pistons fail. Cause seemingly being the injectors. But he seems to have solved this problem. For now the engine is shelved as he decides what he's doing with it.

He very much did it to prove a point.


Here's a pic of his Pajero He says it pulled like a train and the torque was quite impressive. More noteworthy since he's on 35's!! Also interesting that the gear box took the strain no problem. It could well be that our boxes are as strong as the fabled Hilux boxes.

I've been talking to him about the possibility of fitting his parts to my engine and getting a bespoke remap done. He's intimated he might want to sell it all. If not then hopefully he'll do the ECU mod himself and I will follow with keen interest.

I rest my case. The 4D56 CAN be tuned and for less than the V8 idea.

excellent - i`ve always thought the overheating issues was what caused the head gasket to go , not t`other way round. All my bonnet scoops and intercoolers etc may save me after all

Almost certainly they help Basil. You're twin scooped right? Regardless of how pants it would look, turn one of those scoops round. As per an American muscle car. I know now this will vent heat far better. If you do take your head off at any point, do a port match. This has been proven to lower intake and exhaust temps. Hence why I'm doing mine this week while my head is off. DO you have the Alsport large intercooler? I am now considering something like [URL=Almost certainly they help Basil.

should run on veg as well, as long as its not common rail

Iurn your scoops round Basil, quick screen deicer in winter

My last comment went a bit wrong, but I think you got the point. This is what I want to fit. Werbung: http://www.ebay.co.uk/itm/FRONT-MOUNT-IN...2#ht_500wt_1050

Yep, I would stop short of common rail. Knowing how his tuning efforts went i think our ECU and pump will solve his issues. Those mechanical pumps can't give what ours can with a remap.

Couls use an intercooler from a scrapped new shape its front mounted at bottom of rad.

Is it indeed?? Worth looking into then. But there is more than enough to be said for an oversize intercooler. But it's the front mounting as well that really does it.

I have this

interesting thought reversing the second scoop - it would prevent the ingress of water which was concerning me through the winter
BTW say everything twice, say everything twice! lol

HaHa sorry about that. Think I pasted my whole comment into the URL link. That's a decent intercooler you got there. If you're going to top mount that's the way to go. Assuming it fits no problem under the bonnet?

Yeah reverse facing scoops will vent heat for sure. Problem with both facing forward is that your forcing cold air in but all the heat and cold air coming in have no where to go. So yeah, by rights, you'll cool the hot air some what. But giving that hot air somewhere to go and getting it AWAY from the engine is a better cooling effort. Best way to do that is a front mounted intercooler and twin scoops facing backwards. Could even fit a couple of Demon Tweeks intake scoops into your plastic face plates in the bumper and angle them up wards with some pipe to assist in getting cold air in the front. Heat? What heat??

Ive saw his paj, its really good and i understand what he's done, BUT is it really worth the haslle, cash and the trouble!?

If i was to start again i'd go for a front mount cooler, a hybrid turbo and a few bits and pieces, wouldn't be spending a fortune on it. Does look a ncie engine bay though.

I think you can do a version of what he's done for less if you know your way around an engine. It will cost less and be less hassle than pioneering a conversion. Plus you can still run it on veg. Vince from elite4x4 will do a V8 but who wants to offer up their truck? The 6G72 V6 will drop straight in, wiring loom, ECU, pump and tank needed though. Add a couple of turbo's and she'll put out over 300BHP. So that's the obvious BIG POWER option for us L200 owners. But otherwise what do we have? A crazy one of cummins or 3.2 conversion? That's WAY more hassle.

I think the moral of the story is that anything is possible if you spend enough money to make it happen

Yep. That's about it matey. But it does prove it can be done. It's your choice to do it.

Same with that Supra motor'd L200, the bay will hold almost any engine, its big enough.

I've got a soft spot for old volvo engines. Can get plenty of power and bomb proof!

Stick...... it can indeed. Not forgetting though the issue of retaining 4wheel drive. Remember the "fitting a V8" thread....... For me I cannot look past the obviousness of the 6G72 if power is what you want above all else. Mitsi parts, Mitsi truck, it matches. No need to fabricate anything.

Rob.....good engines, but you've got the same problem as I just mentioned. My mission was to find a solution that we all could employ. Not one offs. So when people come along and say I want more power we can give them stage 1, stage 2 or stage 3 for the 4D56 or the V6 option. You know kinda how the hilux boys have it. There is no thinking involved. They want more power they buy off the shelf parts for a V8. At least we have solutions now.

It was all much simpler in the good old days, 1.3 Escort not quick enough, 3 litre Capri engine, box and running gear straight in, next to no wiring, no ecu,s
Turbos etc......where did it all go wrong

Around 1990 mate,

Twin 45's still rock over ecu's.

I must admit i would love a stonking cumming derv motor in mine but i dont have that much money.

I used to have twin 45`s on my mk1 mex - that did about 25 mpg too!

It was affordable then!!

I Must admit, i like the idea of the posh looking engine bay even though you very rarely lift the bonnet to show it off, lad at wrok has painted parts and chromed parts under his and it looks decent, just a little voice keep syaing, is it worth it!?

gonna investigate the reversing of the second nostril tomorrow- shouldn`t be too difficult, the bolts are symetrical on the template, so it should just be a question of turning it round and resealing round the outside

Yeah but how much fun was it I had 48's on my Burton pinto, don't think I even got 15mpg but I didn't care

Hi lift piper cam, double valve springs , 188bhp (as was) at the back wheels, mk2 RS2k axle with lsd, gussetted, all lines inside, recaro`s - it was mental - and died a horrible death
