More Power

[tim devlin]

Udhi,
I'm in the same boat i use mine daily and as it's all town work my mpg is poo!
But I will ask him and post his reply ASAP.
Keep you all posted,
Tim

Most of the companies that perform this type of mod (ecu) claim that it improves the mpg as they can tune the engine without making the compromises that the OEMs have to.

A question - does the 185 (3rd Gen) have an intercooler? they use the same engine dont they? I would prefer to keep the intercooler within the engine bay and add a scoop if necessary.

Yes they do but not all of them.

Ali,
I think the argument is that with judicious tuning, you are going to move more of the power downstream of the rev band. This essentially stops you from thrashing its nuts (Metric, y'know ) off to accellerate, drag heavy stuff etc etc. The implication might be that if you set out to use the 200 BeJeesus that Allard might get you, you will pay for the fuel burnt to deliver it all.

So engine efficiency itself may not be bettered, but Allard might have the secret to human perception of power - lots of go for very little pedalling so it makes us less rev-happy.

.....hope this makes sense, if it doesnt, I am really an escapee from the local loony bin y'know, wouldnt trust me

Two comments
1 - Do you think we can bring the other thread here (intercooler), It would be better to have all the info in one place.

2 - the use of an inter cooler, changes to the ECU and turbo gate CAN result in making the engine more effecent - which would produce better mileage for a give performance.

More Power - Total Mods

It seems to me after much reading here and on similar forums that if you are after more power, even a small increase, then the folowing will have to done.

Timming Belt
Unless you have (or had) replaced it recently they replace it

Cooling System
New water pump - it seems that the new ones are more effecent and shift more water (different impeller design) This also needs to be done when replacing timming belt.
Radiator Modification
It seems the the cooling system is only just capable of copping mainly due to poor radiator design - a/t cooler interference with water flow. Therefore a modified and/or larger radiator is requiored - especialy if you go for 200+ as more heat will be produced in the system.

ECU
remapped or plugin

Induction / Exhaust
Intercooler (get more air in)
Turbo gate (control of above and below)
Large dia (3") exhaust for freer spinning turbo

Any comments - is this over the top or is there more to consider - I also think that if you are serious about this then the torque converter and the auto box will need a good look at.

That is a pretty thorough look at modification Ali!

>Timing Belt

Mine is only 12K old. But I have no issues about changing it if its deemed needy.

Ditto the waterpump.

>Radiator Modification
Mine is a Manual, so there arent any AT stuff in there, playing gooseberry. Even with stop start driving, My Oil T has never risen to hit the mid point (most efficient) ditto for coollant Temp. Who knows increasing the temps by the tuning might actually increase the temps enough for the engine to hit proper working temps!


>ECU
>remapped or plugin.:

I think this is the plan With Allard or Aaken.

About the Thermostat.
The therostats might be different between Japanese and Uk models. The Jap models might run cooller than the UK as the thermies may have been set to open LATER in the UK ones.

The reason I think this is that I had a JDM Honda Del sol. It never hit the middle point of the temp range. So I changed the therostat to a UK model and Voila! it warmed the car up much quicker and was always on the mid level of the guage.

Now, if the Surf's Thermy is set to open relatively too soon in the jap models and hence maintain the vehicle at an overall lower working temp than is good for it, the increase in power is going to benefit us more than in the case of UK 4Runners.

Hope all this makes sense - I am running low on sugar

Udhi,

I think that the radiator limit is just OK with stndard manual and hence many more problems with autos. If you are serious about the power boost (200+ bhp) and not just an ECU/addin, then I think that the radiator will not be able to cope. I have seen threads on various sites where manuals have had overheating problems - OK these have been in extreem conditions but that level of power increase is going to produce a lot more heat.

Not sure about the thermostat bit as N Japan is a lot colder than here in the winter (the sea freezes!!) and S Japan is a lot warmer (30+C) and thats just within the main four Islands.

My main problem is that in the new year when I have some money to do some mods I'l not have enough for both a 4" suspension lift and engine work - and I'm not willing to compromise on either.

Oh well

Ali

[UKWolf]

Oh - and bumper mods for winch and tow point, roof rack, lights and snorkel

Were does it all stop

Ali

[ChasesDragons]

I Understand your point regarding thermostat and big diffs in temp over Japan - this was never mentioned when we examined the Del Sol prob. The Sol DEFINITELY did pick up in temp when we fitted the UK CRX MK3 thermy on. Might be type-specific.

I wonder how well controlled the car is gonna be with 200 BHP and an increase in Centre of Gravity from the lift. Would be fun to test

There has been no reply from the kiddy negotiating with Allard, looks like he might have decided against the job.

Well the only thing you need from Allard is the ECU - but there are other companies that do it, so we will have to ask them.

The rest of the work can be orginised by ourselves from other sources or DIY

This was sent to me by Jon Ogmundsson from Iceland.
QUOTE:

My car is a 1994 Toyota 4Runner 3.0 turbo diesel
The engine is 1 kz-t.
The diffrence between 1 kz-t and 1 kz-te is that the e stands for electronic controlled injection system.

When fitting an intercooler to these engines, both models need fuel system tune-up.

Now doing that for the 1 kz-t is easy, just tune the system to give more fuel to burn with the increased intake air density.

To do the same thing for 1 kz-te is a whole anoter story, a computer chip in the engine control has to be replaced to adjust the fuel system.

As many of you guys there have the 1 kzt-e engine, I know Toyota Iceland has been adding intercoolers to a lot of Landcruiser 90 models witch have this same engine.. 1 kz-te, and therefor know about the chip needed"

Webmaster/Forum ops - if these are too large, let me know if there is a better way to publish them.

just looking around and found this http://www.dieselbob.co.uk/ what do you think?

A bit late here, but having had experience of a Mk2 Turbo MR2, I doubt very much that a ram air setup will make an iota of difference to a turbocharged setup! The lower the restriction the better, but air being forced in at 60mph will make butter all difference. A small difference to a NA engine maybe, but turbo? Forget it. Cold air with as short a path as possible will be better.

Well thats a lot closer to home - I may have to give them a visit
