Default Good replacement turbo for EJ20G?

I just pulled my turbo out of my 93' WRX because it was whining once it boosted past 3psi and I was looking into trying to get it rebuilt but another thought popped into my head. Why not do a little upgrade? Do you have any ideas of a turbo that will just bot up with no problems? I will be doing down-pipe injectors and a little meth as well.

Thanks for your input.

well.. i think your turbo has a 90 inlet.... so if u upgrade you are going to have to get a 90 elbow, for the inlet... i think.

That is true. Thats why I have having a harder time looking for a turbo.

The rebuilding it into a 18g does interest me though. I have never heard of that being done before. Can some give me a little insight on this?

18g will be a sweet upgrade but turning it into a 20g will give you even more power potential. Depends on what you want out of your car... The 18g will give you more midrange and the 20 will hit harder up top.
Both the above upgrades are easily done on your td05 as they are both td05 based turbos anyway. The only thing that changes is the compressor section( wheel and housing). Some places can even use your existing compressor housing and machine it out for the bigger wheel. This is not the most efficient solution however but still a decent way to make more power while looking factory stock

Both would require larger injectors and engine management to work properly.

I have been doing a little research on the web the last couple of days and is it true that you can machine the exhaust housing to fit a 18g compressor wheel? or even a 20g? Does anybody have experience with this and how much power do you think I will make? I am looking for 270whp-300whp.

20g is stupid on a 2.0
an 18g will be laggy

think about a rebuild with a large 16G
had you considered the whine could be a boost leak instead of a dead turbo...

the charge pipe is prone to cracking

have you looked into some other upgrades before the turbo?

My current setup on a EJ20G is putting down 290+AWHP with the stock TDO5h with full boost of 16.3psi at ~3650 RPM. i think the turbo is still good up to 300 AWHP with supporting mods.

I would send your turbo out to be rebuilt, and maybe PNP, or some other small upgrades. but i would not start looking for a different turbo right off the bat.

"20g is stupid on a 2.0

ummmmm no!

I do agree with the rest of the above post..... Some people on here are soooo damn conservative. Greddy serves you the 18g for 1.6 civic si lol. I spooled the 18g with no problem with a 1.6 single cam. Do what you like and make as much power as you want. You are not stuck with a stock td05.... dont let anyone mislead you into thinking that.

The fastest spooling turbo on earth is not what everybody feels is most important and thats why god created an "upgrade" There are plenty of bad ass 2.0 ej20 out there pushing 18g, 20g and bigger... just search and you will find what you are looking for.

I would personally go with an 18g...... hehe actually that is what I went with . Will be installing in a couple of weeks... just waiting for the car to come out of the bodyshop(fresh paint job)

By the way the stock tdo5 16g will give you around 330 or so to the wheels at max depending on mods. If you havent maxed it out yet you might want to feel that first before jumping into big turboville. The weight of our cars(gc chassis) makes it a beast at that power level.

i think people need to put into perspective just how fast 280whp even in our cars is (super easy with this turbo)

rebuild it and pnp with a big or evo 3 wheel.

Well I looked into how much it would actually cost to rebuild the turbo were I live and it is going to be a good $850 so no point into putting that money back into that old turbo were I could just buy a new one. So that is the plan and Ill probably throw in a big evo III or something around those lines. Does anybody have one for sale? Lol

I just bought an EVO III from Kinetic and installed it today, I'm pretty happy so far - just need to let my car adjust for it. I have a feeling that the wastegate must be set around 10psi instead of the stock 7psi because I'm hitting boost cut now even after reinstalling the stock restrictor........

My car is auto and had a TD04 - I think I need a torque convertor to go with it, spool is probably 1000rpm later than stock, but mid range feels so much stronger and the top end is awesome until I hit boost cut........

I just went with a straight front entry turbo for a late model. The top coolant line needs tweaking to line up and I bought a 2-1/2" silicon 90 deg and trimmed it right down (2-1/4" would be better, but I couldn't find one) and then also cut a short piece of 2-1/4" exhaust tube to use as a coupler to mate up with the stock intake tubing.

Taken from the Andy Forrest page:

AFP5-16 - is based on the 90 degree inlet TD05 16G from the 93-96 cars and can also be converted to front entry to suit 97 onward cars. This turbo is very popular on installations aiming for up to 340bhp. It is available as a fully re-manufactured unit or new. This turbo will typically spool up to 1 bar boost by 3000rpm and full boost by 3300rpm.



320 exchange or 600 new outright (includes 12 months warranty)



AFP5-20 - this is also a variation on the TD05. This time fitted with a much larger, high efficiency 20G compressor wheel and compressor housing. The high efficiency compressor allows the turbo to run at a lower rpm whilst still producing boost. This results in similar spool up to the 5-16 but with a 50bhp increase in airflow capability. This was the turbo used on our own RA to produce 440bhp (running fuel additives) . Up to 400 bhp is typically achievable in conjunction with full supporting modifications .

This turbo is very effective on the 2.0 and also 2.5 conversions with 1 bar+ boost coming in around 2600rpm on the 2.5

795 new or 550 exchange (includes 12 months warranty)

If you require the exchange unit prior to removal of your old turbo then the returnable exchange deposit required on all TD05 based units is 200.




















Enough said.
