ok people i thinkin bout turboin my qg15DE, what do you all think? should i abandon the project cause it would not make sense?

IvanTerrors · Postby **IvanTerrors** » November 3rd, 2007, 7:49 pm

i also ha a qg15

u could probably safely run about 5-8psi on the qg wit stock internals but u'll need the turbo set up and bigger injectors, better ignition, more fuel, exhaust etc

...take it out and put in a sr20det less stress
and more power..u'll also need to upgrade ur brakes, fuel system and strut bars if u dont already have

true. go SR. alot more power for your $.

Only way i can see you doing this, is to be "the guy" with the Turbo QG15. Other than that, its not worth it.

It would be nice to have a QG15 turbo in the country for a change

. SR turbo will have plenty of power but the the turbo QG15 would be cutting SOHC Vtec arse

So you think.. all that money you are going to spend to end up with 30whp more ( if your lucky ) :lol:

^^^Exactly

t would be nice to have a QG15 turbo in the country for a change Very Happy . SR turbo will have plenty of power but the the turbo QG15 would be cutting SOHC Vtec arse

People feel turbo is magic. I'd love to see a "Mango tree turbo kit" QG15DE [sarcasm](knowing the "wealth" of aftermarket parts from HKS and GReddy for it)[/sarcasm] beat up a VTEC, MIVEC, or any "EC" any day. :lol:

Yeah right :roll:

I drive a QG15DE. It's a nice performer, but it's a grocery getter. Period.

^^And with stock internals too, QG18DE-T was actually reported doing 200hp with the 10psi boost, (TD04 subaru turbo).

HP is nice. TORQUE is the pull. What torque was he putting down? And where was his power band?

Picasso · Postby **Picasso** » November 10th, 2007, 9:53 am

^^^ A stock SIR got more tq than when you boost a QG15DE and QG16DE.. Their are guys on www.pulsar.org who did this and they were happy for only a while..

moti · Postby **moti** » November 12th, 2007, 1:20 pm

do mods like intake exaust plugs brakes etc. dont waste your time to turbo a qg
1.5 or 1.8.

you want turbo go sr20 or hr20

In Hungary at the moment is running 2 almera with QG15DE engine and turbo. It is also possible the upgrading the stock engine.

One is running with a KKK03 turbo, the second with T03/T04 hybrid.
The first engine go with 0,5 bar (approx 7-8PSI and produce approx 160PS), the second sometimes over 1bar and now is working properly.

Can somebody tell me, which size of injector use the QG15DE and the QG18DE? If I would change the stock injectors, which size should I take? (340 or 440)

The connecting rods are the same in the QG engines, and also in the GA16 engine (88mm stroke). It can support a little bit more than 200PS.

The weakpoint is the pistons. One of the MAZDA pistons are the same bore that the QG15DE engine (73,6mm). Maybe it can be usable.

Know somebody forged pistons for a QG15DE engine? (not a custom made)

^^^ do you realy think after spending all that money and you meet a honda guy or a Corolla lova with a high rev 1.6 with just a modified brain that makes just a lil less power than you but for some reason off the line you get 3 lengths in 1st gear, and a nasty 4 lengths by the time they pop 2nd?

I thought of doing this long time and followed nissan performance mag project with the QG18DE-T project which took some effort just to cross the 200hp mark.. A turbo charged SR18DE will give you more power, it's dam stronger, more options for aftermarket parts, more money in the bank ( proven and done millions of times you can't miss ) and better yet once done properly can leave you with the shaking right foot syndrome.

rallyequalsrace · Postby **rallyequalsrace** » May 22nd, 2013, 11:37 pm

sr is an heavier engine than a QG18....i have both in the same type of cars...all non turbo....the QG wins all the time.....looking to put the QG on 7 Pounds very soon.....just looking for more power when the ac is on.....

zcarz · Postby **zcarz** » May 24th, 2013, 12:25 am

So maybe a slightly related question.. I'm thinking of turbo charging and inter cooling my sr20de.. Td04 turbo on like 6psi. Problem is my car is automatic and don't wanna change the transmission just yet.. Will the auto tranny be able to manage with that kind of power (estimate maybe about 200 hp)

Ted_v2 · Postby **Ted_v2** » May 24th, 2013, 12:32 am

Yea. With a cooler. Pm the syndicate, a b12 guy. He has his sr20de boosted with a normal sr20det turbo, he is also running auto transmission

Thanks a lot man will do!

once you have good management you good to go

Postby **nervewrecker** » May 24th, 2013, 2:47 am

Already did my research on this, SR20 is the answer. Turbo Qg = waste of $$$ and effort.

so one might end up in the mera?
