[Mk2] [Turbo] Rev 3 wiring conversion?

[kev_mr2]

so if i was to go down that route id need to change the injectors for say 800cc ones and then the pressure regulator aswell?

once i have done that i will then have to get something to control the injectors? Power FC or the SAFC or whatever it is?

i was cosidering using the Power FC but im gonna stick with the Rev3 ECU and setup just to get used to the big change over standard BHP figures

[tarmac terrorist]

mine runs 800cc with power fc you dont need the fpr thou

[kev_mr2]

cool

im hoping to get around 300 to 320 hp. would the standard rev 3 stuff cope at that?

[tarmac terrorist]

i thgnk it should be possible i got 355 flywheel when i was running standard rev2 ecu 440 injectors with hybrid ct26 & forged pistons

[kev_mr2]

hmmm i already have the CT26 hybrid and aload of other mods. not got forged pistons i dont think. any way of checking this?

what sort of pressure were you running at to acheive that figure?

[tarmac terrorist]

i was running 1.3bar ,im not shore the easiest way to check the pistons mate

[kev_mr2]

blody hell. im only looking to run 1.1 or so lol

maybe got my hands on a rev3 shell. uk model though. will wiring just be plug and play and no pin swaps?

[tarmac terrorist]

couldnt tell you on that one mate im affraid

[kev_mr2]

no worries mate

just had a peek and my pistons have "2E" stamped on them and are a funny shape lol

[tarmac terrorist]

2e sounds like the standard toyota stamp on them to me it normally determines there size

[kev_mr2]

so with my list of mods on this engine, do you think i should acheive the 300 mark quite easilly?

Rev3 ECU and fuelling setup obv
CT26 Hybrid (i think its the 48mm compressor wheel) if i set it to 1.1 or 1.2 bar
induction kit
Uprated intecooler
Blitz decat and turbo elbow into a 3 1/2" exhaust
Grade 7 plugs and KV85 leads

[tarmac terrorist]

i think it should be possible mate, before you start raising boost just get it on a dyno to check you fuelings ok,WARNING at some point thou if you have a standard rev 2 headgasket it will let go, the more boost you put through it the sooner it will go

[kev_mr2]

yeah the plan is to have it mapped and well ran in before doing so!

i aint taking any chances with it. The head is off and away getting ground along with the block so i have a super smoth surface for the steel gasket to go on

yeah i have ARP head studs which i removed from my last build that went wrong due to tensioner failure. I used a cometic MLS gasket on that.

Im going to get another one of these gaskets but should i retain the standard thickness or go for a 1.2 mm?

[tarmac terrorist]

the thicker the head gasket the more boost you can run but the less torque you may have lower down,(due to lower compression) although with the head & block face shouldnt be much different from standard i would go with the 1.2mm should be fine thats what i used to run, i now run a 1.6mm HKS

[kev_mr2]

ok turns out that the engine is a rev1 instead of a rev 2.

does this make it any easier/more difficult?

[kev_mr2]

Got the Rev3 engine loom yesterday.

was comparing the differences today and noticed that some of the plugs are different on the Rev3 loom compared to the Rev 1 loom. Fuel pump relay one and 1 or 2 others. can i just swap these plugs over from my rev1 loom?

also the rev3 loom doesnt have a single connector that goes to one of the sensors on the water housing connected to the head, is this needed as the rev 1 loom had it
