American with some 1kz questions

Joined: 21 Aug 2003

OK im intersted in maybe doing a 1kz conversion here in the US but need some info. Does any one here have a engine & chassis wiring diagram for a prado with the 1kz & 5 speed transmission? Also what transmissions came with this motor and what is the HP & Tq ratings on it in the prado? Thanks.

ill check for you tommorrow on the power rating and the wiring diagram should be available from toyota here, if not it will be in the work shop manual and if that is no good i could sell you a complete wiring harness if that is any use to you.

Nick prob wont be back on for a couple more days. He usually only gets on Thursday nights and Weekends.

Yes he should also be able to supply an engine and transmision along with anything else you need for the conversion.

This may interest you. Its a link to download the 1KZ-TE engine workshop manual. 14.5 meg but worth it. Genuine Toyota.

Glad these guys could help you TR!

I am sure there will be more. To my knowledge a Prado with a manual does not exist. At least not as a factory option, so the 5 speed may be difficult. Not interested in the auto??? Ill buy it and the chain drive t-case off the conversion probably. Id say manual conversion woudlnt be too hard!

there are two engines around one intercooled one not, the only other different this to ECU in the two engines other that that they are the same 1kz-te the intercooled version found in the prado (oz) is 96kW and 343NM the non intercooled but still has a turbo found in hilux (oz) you guys have the tacoma - 85kW and 315NM torque auto available on the prado motor but not the hilux engine. best of luck

Humm well a hilux version would be better cause i can always add a intercooler & do they make chips or any other aftermarket parts for it? Also i was looking on the net and found the 1KD-FTV engine. would it also be a good canidate?

BTW that PDF didnt have the wiring diagrams in it.

yeah they do an up grade chip here in oz its about 1500$ aus its called dtronic it is fuel management system that can be plugged in and out as desired to restore factory settings. - www.dtronic.com has a site about it made by safari - they make pretty good gear.

humm ok so the 1kz makes 114 hp and 232 ft-lbs of torque non intercooled. Ive heard that it comes with the R151F tranny with the 4.31:1 first gear. is this the same tranny that we have in the states and could i bolt a gear driven case up to it? Also the fuel system, does it use a low pressure pump to get it from the tank to the injection pump? and does it use a electric fuel pedal or a cable to the injection pump? Thanks again.

as for the transfer case not sure - i know that the landercruiser over here the base model with the naturally aspirated diesel has the same gearbox any help? - not 100% sure but i think that the line from the tank to the injector is low pressure you should double check with the throttle - its still cable on my model (sept 2001) i think that the new ones mid 02 onwards are electronic.

TR, the R151F is used on the Toy (Hilux) Turbo 4x4 in the uS. It is mated to a gear driven transfer but the rear output is centered. The input shaft may be different, I don't know. You're looking at the eBay engine? It looks sweet.

Goodsy you listed the final drive ratio as 4.556:1. Just wondering where you got this figure from. I have a 2002 hilux brochure that lists it as 3.727:1 for the 1KZ engine with R151F box. I am putting a 1KZ & R151F in an 84 hilux and am still wondering about diff ratios. (obviously not running yet but ready in next few days to try kicking her over).

Copied and pasted figures from carpoint. You are right final drive figure is wrong. Didn't think to check them.
