If I replace the 13g turbo with a 14b, what else do I have to change along with it??? What SHOULD I change along with it???

TalonTsi97 · 02-18-2007, 02:12 AM

Change the injectors for sure, and i wanna say the ecu to a manual one but not 100% sure.

Do I have to change the manifold or the 02 housing??? I hope you don't have to change the ecu.

You dont have to change the mani and o2 but usuallu 1g peices crack easily and will need to be upgraded to stock 2g peices, and while you have the parts off i would port them instead of taking it all back off when your ready.
I wanna say you have to change the ecu but dont hold me to it, maybe someone else can chime in and verify it.

also i have a 2g exhaust manifold and o2 housing if your looking to upgrade, just pm me and we can work something out

I have heard that the mani's do need to be changed. You will need 450cc injectors and a manual ecu will compensate for that. The manual ecu comes with a more agressive timing map then the autos do. I would just do the a 2g mani and a 2g o2 hosuing while your at it.

Which ecu do I need?? Eprom, non eprom. I don't even know what that means but I see it all the time. Should I get the same year ecu as mine??

Since you're a 91, you should be able to use any 1g turbo ecu.... with certain years you have to change 2 wires at the harness... I believe it is if you use a 90 ecu.

SpendOne · 02-19-2007, 10:37 PM

Its up to you if you want to chip teh eprom. You can use any "turbo" ecu from 91-94.

assault187 · 02-20-2007, 01:58 PM

if you need i have the 450's if you need them

Thanks but my buddy just gave me a set for free.

You'll need a new manifold and coolant lines to bolt the turbo up. Injectors and a 91-94 turbo manual ECU would be a good idea also.
