Turboing A Lexus

[TomCooper]

Hi i dont own a lexus yet, but hope to have 1 very soon, just wondering if it is possible to turbo the 6pot engine, or would it be better for me to find a lexus with a different engine?

What modifications will have to do to the engine to run turbo? or can i run 1 with low boost without changeing to much of the engine internals?

also will i loose lots of mpg turboing the engine?

cheers

Tom

Two choices:

IS200 1G-FE which is good for 250bhp / 7psi boost without upgrading the internals

IS300 2JZ-GE which can be taken to 500bhp / 24psi

supercharge it, bolt on kit :D

[DAZA_W]

or do the internals and get 300bhp plus do a search there is a lot of talk on this

[TomCooper]

ok next question, how do i know which car has which engine?

All standard is200's have same engine :D

Check the bold bits :P

Another option is an Altezza RS200 - the 3S-GE engine, not sure how high that thing can go but a couple of the lads on here are pushing the 300bhp mark with a bolt on turbo or supercharger kit :)

i would, but hard to get hold of and as rare as anything...

so what engine does the is200 sport come with? and is it turboable?

All IS200's have the 1G-FE engine, as stated above.

Yeah basically mate the IS is only available with two different engines - as the boys have said the IS200 is the 2 litre version with the 1G-FE, and the IS300 is the 3 litre version with the 2JZ-GE, same as used in the NA Supras I believe?

The only mechanical differences between the IS200 S / SE & Sport models is that the Sport has slightly lower springs and the LSD - everything else is cosmetic stuff I think, apart from the radio, the SE & Sport both have an extra amplifier which is supposed to sound better - never heard the stock S unit so can't comment, and the Sport has rear tinted windows...

ok cool, is the is300 a 3 litre? or is that just a stupid question? never really seen them about?

[Mr Morse]

Yes it's a 3 litre straight six, the same engine in the GS300 MkII and the N/A Supra MkIV

[Rsarin]

go for a 300 if you can.you probably would end up being happy with the power for a while,im sure

[waddy]

The IS300 is a 3 litre. It is different to the IS200 unit, i.e. not just a bigger bore. The IS200 unit is a fairly old design which doesn't really push the boundaries - hence it is so reliable.

Mr Morse is currently tinkering with his IS300 - might be worth having a word.

The 300 is an auto however and produces 212bhp (or around that mark) as standard. They are more expensive though, think you'll still pay £15k plus for one.

Best people to speak to are TDI or Prolex - they are the experts.

[Rsarin]

you dont need prolex or tdi for this,speak to mr morse or scarface, go on the us forums to investigate the IS300.Prolex can source you a rotrex charger,or maybe Mr morses old one,but only once youve decided that its the right thing to do.Speak to IS300 owners,they are the most informed cats.The 300 is sequential(e-shift),so better than auto

[Mr Morse]

If you decide you want an IS300 and a supercharger, I have a complete Toyomoto kit with all the bits and pieces to fit straight on a 2JZ-GE and good for 320bhp

[TomCooper]

*******, alot of power there, 300 would sound better, im used to 250bhp from my rover, but i fear the insurance on a 3litre might kill me.

will the reliabilty be lost if i wacked a turbo on the is 200 1G-FE engine?

and how much bhp will i be getting?

[Rsarin]

are you 20 tom?if so,whats your insurance premium like at the moment on a 250hp car?id imagine its quite expensive.

[TomCooper]

Im 22 now, was 20 when i did that post, wow 2 years ago... on my rover insurance is £1500, well it would be... but i only pay insurance for the days i use it. like weekends or car shows etc.

What happens if the car gets nicked though - guessing basically it's uninsured, or do you have 3rd party fire and theft elsewhere on the car (if you can even do that?)

[TomCooper]

if its nicked them im screwed, but its behind lock gates and its not very easy to steal... well they might get about 1/2 a mile before it blows up... or they loose control, rover has big problem with over heating, ive always gotta top water up and have fans on before going anywhere... if i dont i blow the head very easily... lol

interesting, i wasnt aware you could do that

makes it about £3700 a year

might solve a problem i get occaisonly :D

how do you get on with buying tax for it ?

[TomCooper]

lukily i had it insured for few months over the summer when i got it taxed and mot'd so no problems there, but cancelled insurance cos was paying £1500 a year and used it less than once a week, not to mention it went about a month with no engine in it. Not the most realible car in the world.

Yup is handy www.dayinsurance.co.uk
