Custom turbo build help
Custom turbo build help
This is where a super/turbo charger comes in. I had originally planned on getting a TTE charger, but they're few and far between, and seem to have a fair amount of miles on them. Plus, a 50hp gain for about £2000 doesn't really seem all that great to me.
So I've decided to go down the more complicated turbo route. I'm thinking a reasonably sized single turbo, T3/T4 sized. However, having never done anything like this, I am trying to do as much research as possible, before I shell out for parts that I'll have to try and sell on when I realise I'm out of my depth.
Firstly, what exactly do I need? I'm aware that I need the turbo, BOV, manifold & wastegas, downpipe, intercooler & pipework. Will I definitely need uprated fuel injectors and boost controllers, etc?
Also, what in the way of tuning needs to be done? Say I fit it to my car, will a second hand ECU be alright, or since it's a custom build, will it need to be dyno'd and tuned before it can be driven anywhere?
Thanks for any help. I'm a bit of a noob when it comes to tuning, but I'm fairly handy with a spanner lol
Basically, I've got an IS200, and whilst the power was alright at first, it's starting to feel a bit lethargic... A common complaint, I know. However, I absolutely LOVE the car, I've spent a fair few hours and £££ on it already, so I don't wanna part with it just yet.

02-08-2019, 07:18 AM #4i did a turbo build 2 years ago..... lots of things you will need. big shopping list and money for it all.
As a stock engine, with the twin turbo set up, Wikipedia says they made 185-210bhp stock, but no idea which model/year the larger power version came in.
Just wondering, even if you got the 210bhp version, is the hassle and cost (no idea how much of either is involved) worth it for an extra 50bhp? I'm guessing, like the TT Supra 2JZ, if you want to run decent power through it, you'd need to mod it a fair bit; single large turbo, management, etc etc.
Or can the 1G-GTE be made to sit happy at about 280bhp all day long, and retain smooth power delivery and non-offensive drivability, for not a great deal of work/money?
Is a 1G-GTE transplant worth doing? I know Stav's done it, but his is also pretty modified too, no?

even think of a 2jz set up as there is one out there.

02-08-2019, 09:06 AM #6i think you can push the 1g gte engine upto 300 if you change to single turbo like the 2jz
even think of a 2jz set up as there is one out there.
And the fact the 1G is the same family, it should be a simple mount and gearbox mate, no? Whereas the 2JZ would need work to get it bolted up and the gearbox fitting?
Well that's what I was thinking, if I was to do a turbo conversion I'd do a single, but if I was to do a swap, with a 1G-GTE, I'd probably want to keep the twin turbo set up, as I understand the way it works is much like the 2JZ TT; it boosts from very low revs, and the second turbo doesn't cut in till later on? So it makes a decent amount of BHP, with a shed load of torque, from 2k and under, then pulls all the way to the redline with the second turbo coming on song at about 3500/4000?

Matt_C 300bhp would be nice, but not really needed. 260 would be perfectly sufficient; 280 would be more than enough.
250 feels quick - 300 is spot on.
