na turboed?

[soutahmk3]

ok i would like to know what kind of power gain i can get from a turbo on my na? i have the manifold but am looking for the turbo, harness, injectors, cams, and ecm....but any who what kind of boost can i expect to get from a ct-26?
i kinda want to go stock turbo?....oppinions welcome....

 

[boost fiend]

if the wastgate has not been modified or shimmed, you can expect about 6.5 - 8 psi of boost.

but if you then decide to shim the wastegate, you can hit upwards of 14 psi. but, with using a turbo ecu you have to worry about fuel cut off. nice design and idea!! keeps you from blowing your engine. there are many adapters and/or piggyback ecu's that can push f.c.o. farther.

and, iirc, the stock ct-26 is good till about 20 psi before it becomes too overworked.

but then again, your a n/a originaly. that can change a few things in the mix there, so i might be a lil off on my numbers there.

youre GE motor (if its in good condition of course) turbo'ed would make more power at stock boost than a GTE motor would make at stock boost.

 

[soutahmk3]

thats what i was thinking becuase the na is like 9.5 to 1 compression ration and the turbi is some where closer to 8 to 1 i m not exact on those numbers but i have been reasearching it.....i think i will go with a satand alone fuel management sys. i alrady have my laptop set up to do so i figured as long as i provide it with enough fuel i could get little more boost that way....

Yes this is possible. Yes max boost would be 8psi. Be ready to make around 285 on a HEALTHY N/A AND A HEALTHY CT26. The n/a needs to have a mhg or kiss it goodbye.

You also need some injectors and a way to controll them.

Last, make sure your fuel system is up to snuff - IE your filter is changed and you're running nothing but 93+ gas.

well its a jap motor i orders with everything on it i dont know if japanese engines come with a mhg or not but you think i should put one in just in case?
the car runs strong it doesnt have any emmisions or a cat and i still dont get a engine light unless i get bad fuel then i get an o2 sensor but with the three in exhuast i have it lives in the top end i originally installed the big exhuast to accomidate the turbo by the way if anyone has a turbo they want to sell let me know!!!!

 

[MDCmotorsports]

No 7m's come with MHG.

Put one in, alone with ARP hardware.

 

[soutahmk3]

arp head bolts or studs? probably studs right?

 

[Yellow 13]

Studs FTW. like 10 dollars more so just do it.

studs are better but they do come with a downside, if you ever have to take the head off while the motor is in the car itll make it a real pain in the ass with the studs.

 

[SublimeSupra]

I thought you couldnt use the turbo ecu with the n/a because n/a has distributor and turbo is coil pack.

 

[pimptrizkit]

it's the same head, just different cams,

im actulay running the n/a cames in my gte right now.


the cps will bolt right into the distributer, ( if planned to swap electronics...) only down side is there i sone knock sensor on a ge. so you will have to do some research about that..

i would also say make sure you get your head & block machined / prepped for the mhg, this way it seals perfectly and you dont havy any problems. like meeh.

 

[shaeff]

hte cps doesn't bolt into the distributor, it replaces it. if you run a turbo ECU, having adding another KS isn't difficult.

-shaeff

 

[pimptrizkit]

would you drill for the new knock sensor?


i have on last n/a block i think im going to start prepping for my performance build..

Turbo=8.4:1 stock but most are a little higher after block and head surfacing.

I don't see this happening. Don't get me wrong, with the support fuel modifications, you can pull off 20psi on a stock CT26...but don't expect it to last long at all. (I'm also assuming this is a brand new and rebuilt CT26). If it's a used CT26 that's got the life of 16+ years, don't plan on happy day of boosting. If you're willing to do an NA-T conversion, you would be so much better off getting a .57 Trim CT26. Reliable, Makes good power and will last longer than any of the other popular upgrades (60, 60-1, 62-1, etc).
If you are looking to just run stock boost or anything below say 12psi or so...You should be fine...Just make sure the turbo you use is in healthy condition. :icon_razz

thanks guys this stuff is really helping i appreciate all the info and help!!!
now i kinda know what to expect going into this..
i am also working on putting a turbo on my jeep cherokee just for fun....

 

[Yellow 13]

So...can you run a GE on CPS/Coil pack with a turbo ECU?

 

[amd_hcds]

Yellow my car blew it's turbo and i couldn't find any turbo to replace it and it was my only car so i just removed the turbo and installed an n\a exhaust manifold and it ran great a little rich but not too bad and then again the engine blew a hg and after that rod knock so i decided to rebuilt i had to replace the pistons so i went and bought ge pistons cause i couldn't find gte ones and i don't have a turbo so i would need the extra compression to help my car a bit until i find a turbo so technicly the car now is a ge running on complete gte electronics so i guess you can run a ge on cps/coil with a turbo ecu and i don't have an explination but after i went with the ge pistons the car ran great no rich.

So...can you run a GE on CPS/Coil pack with a turbo ECU?

And a GTE harness with GTE injectors and GTE airflow meter, etc etc...

Or search Ebay for the old HKS turbo kit parts and Cartech turbo kit parts. The HKS came with the PFC FCON chipped for the 7MGE. I think Cartech was using a fuel management unit.
