1JZ-GTE in to an IS200

[ellz]

Hi guys its taken me a bloomin age to get on here (roughly 4 months now) but thanks to cptsideways i can now come on and get the answers im in need of.

A quick bit about me, im currently doing a motorsport engineering degree so me and a friend has set up FP racing to get some racing experience to go with the course.

Have a look here on our webiste for details

http://www.preponderance.co.uk/Proje...cing/index.php

As you can see i'm dropping the 1JZ into the IS200.

Currently i know i need
- Rear sump
- Engine loom (ive been advise a JZZ30 one as the greedy e manage will plug straight into this)
- Engine mounts not sure on yet (i have been told i can use 2 passenger side GS300 mounts but it sits quite high and as the car will be track use only i may make custom ones to sit it low and backwards)
- Gearbox mounts i believe just need a slight modification.
- Drive shaft mated to a supra one which has the sliding bit in it.

O yeah will be using the R154 box (which needs to be built so am replace the weak point washer with the uprated land cruise one, is this the best option? )

Thats all i can think of now. I think "whatthe??" has done this conversion so he might be my best bet, any other advise is more than welcome.

Many thanks and its great to be able to finally be on here.

Cheers Elliott

whatthe?'s conversion was done by Brett (IS1000) so he may be your better bet... or you can save all the hastle and just buy the car off of whatthe?

Being in UK - that might be a bit hard

[Pimpin_1JZ]

Also speak to Koffe-Black as he had a 1JZ IS200.

meh, he lists his location is Brighton... how many of them are there?

EDIT: in reality, I completely missed the .uk in the web page address

Cheers for the info guy i'll leave it a day or so if those 2 dont see this i'll pm them. Should be looking at around 500hp at the fly as the race series has just put a power limit to make more competetive.

[TasCressida]

hey dude ......

this site has some good info.
worth an email to them.
its 2JZ but should be exactly the same as far as guidelines to fitting etc

once found a wbsite on him using the 1JZ into a IS200 but cant find it now.

hope it helps.

cheers

Was there meant to be a link in the above post ?

[TasCressida]

fark lol ....yep here it is...... dam beer fingers on the keyboard.....

oh and realised ur in the UK ......maybe u could pay them a visit!

hope it helps this time lol

[ellz]

Ahhh saw this a few years ago, i'll drop them a mail.

Cheers

Hmmm, whats the big deal here......... The US Lexus IS300 uses a 2JZ engine.

Yeah its the 2JZ-GE lump non turbo but there all autos

Yeah its the 2JZ-GE lump non turbo but there all autos

no they aren't......... 5 speed was available in USA. and if you look carefully at the photo above you'll see manual listed.........

[ellz]

Indeed you are correct, why the hell do we here in the UK get all the shit models LoL

Looks like i'll be phoning toyota/lexus in the next week to see what there prices are.

Cheers for the info

Be sure to lube up first! No foreplay or backrubs at lexus, just wham! right up to the nutsack!

- Rear sump

Nope - you need front sump.

- Engine loom (ive been advise a JZZ30 one as the greedy e manage will plug straight into this)

I think all 1JZ looms place the ECU in the cabin. The IS200 factory ECU position is in the engine bay, so you need to move a bunch of IS200 cables to the cabin to suit a cabin ECU location.
There are different JZZ30 looms - the VVTi ones have different connectors. JZX90 looms have the same plugs as the VVTi engines. If you pick the right engine the two IS200 chassis plugs will plug into the ECU (might need repinning).

- Engine mounts not sure on yet (i have been told i can use 2 passenger side GS300 mounts but it sits quite high and as the car will be track use only i may make custom ones to sit it low and backwards)

As others have said IS300 mounts are available. You may be better off making custom mounts to put the engine back. The 2JZ engine sits a fair bit forward in the IS300, so moving it back is not a bad thing, especially for a motorsports application.
The factory IS200 fans do not fit with the 2JZ - IS300 fans are thinner.

- Gearbox mounts i believe just need a slight modification.

The JZA80 W58 factory insulator will bolt to a R154 and also fit the pattern on the IS200 crossmember - the only issue will be the distance - I *think* with the 6 cylinder the mount should drop straight into the correct position, but that will be a suck it and see. Whatthe?'s gearbox crossmember has been modified, but I'm not sure how much that's moved forward or back.

- Drive shaft mated to a supra one which has the sliding bit in it.

Not sure what you mean by that? The R154 is slip yoke, not flange, so no need for a tailshaft with a slip joint in it.

Enjoy the swap

Mos owns all with this ...take his word for it ellz.

Wops i meeant to put front sump ive got a rear sump on the block already.

Its not a VVTi engine, ive been advised to use the Jzz30 loom as im using a simple greedy E manage and they sell plug and play for the jzz30 so will be easy when i go big single.

I'm not sure if i'll go custom engine mounts as if i play with them to much then im guessing a new gearbox mount will be needed or made.

The supra's have a sliding part somewhere along the proshaft (ive been advised) that i will need to mate that part to the rear part of the IS200 proshaft to allow forward and backward play. Is this accurate ???

Cheers for the help this is going to be a steep learning curve

[The Last Streetfighter]

Not sure how much help this is, but here is a reply that I got to similar questions, from someone who has done it. (My question was regarding the 1jzVVTi convo.)
Off the top of my head here are some of the issues:
ECU - you have to run 2 ECU's - the Lexus one has to stay to keep the car functioning, and another one to run the actual engine.
Engine Mounts - custom fabricate or use IS300 mounts - I made custom mounts to suit.
Gearbox mount - I used the IS200 one
Tailshaft - get the front half changed to suit gearbox - I used Toyota Landcruiser parts to suit my Getrag.
Diff - would love to change it but haven't found one yet. Needs taller ratio to make the turbo pull harder.
Fuel system - you will have to upgrade the in-tank pump and then run another fuel return line back to the tank as the 1JZ pressure regulator is on the engine and needs a return line. I have a Bosch 044 in the tank. Carfull in there as there is a small lift pump inside the tank to pull fuel from one side of the tank to the other.
Fuel gauge will be wacky and no one has solved that one. IS200 counts for fuel injector pulses and deducts that from the fuel level. Every 1/4 tank it checks against the twin sender units in the tank and adjusts it display so fuel gauge stays still and suddenly drops 1/4 tank at a time.
Sump - You need front sump engine and even then it needs a slight modifcation to clear
Air-con - I used a mixture of 1JZ parts welded to the IS200 hoses and it works fine
Intercooler - I had a custom unit made to suit but I guess the Chaser one may fit
Exhaust - custom unit - I have 3" dump pipe and high flow cat & muffler then split into 2 x 2 1/2" just before goes under back axle with 2 rear mufflers and tailpipes.
Suspension - had to upgrade to Koni's to get the balance right. Felt very front heavy but now has nice balance again.
Other than that it is well worth the conversion.

Gearbox mount - I used the IS200 one.

Mine is just a stock one with some spacers to drop it down about 10mm.

Diff - would love to change it but haven't found one yet. Needs taller ratio to make the turbo pull harder..

All the after market diff ratios for these seem to be taller ratios to suit revvy atmo engines. I am keenly awaiting Mos's inverstigation into gear sets from other models that may fit into the case. A 3.9:1 ratio wouldbe very nice.

Fuel system - you will have to upgrade the in-tank pump and then run another fuel return line back to the tank as the 1JZ pressure regulator is on the engine and needs a return line. I have a Bosch 044 in the tank. Carfull in there as there is a small lift pump inside the tank to pull fuel from one side of the tank to the other..

There is no small pump to draw fuel across but a venturi system that uses the flow of your return fuel to draw fuel into the main tank.
I have used the stock venturi but until the car hits the dyno we wont know if it is going to cause a flow restriction and increase fuel pressure uncontrolably. I use twin walbros in tank so I suspect there will be significant flow returning to the tank. All of it will have to pass through the restrictive venturi.
