L67 or northstar TB ?

[2 loud]

Hi am about to swap my L67 series 1 engine to an L32 from a pontiac GT 2007 ,, gonna go with the stock ecm from my 1992 ssei and will need a new Throttlebody for the L32 engine but what do i want ?? a Series II TB or a Northstar throttlebody ? and iv also been told i need an adapter to fit either of these Y`TBs to the L32 engine/charger ,, so what do i want to use ? not looking for anything extreme ,, 400 + is the goal for this project

How do you plan to tune the PCM for the new motor and setup?

Northstar TB. Either way you need a throttle body adapter. But 400 is a lot for a M90 setup so you'll need the extra flow

well i can go pretty high in pressure since i will run it on E85 ,, ,, 400 is what im aming for but what ever it will deliver will be better then the series One L67 thats sleeps under the bonnet rigth now and to build performance on that engine isent worth ..

but what would you say in the diffrance between L67 series II TB and a northstar TB ,, since these cars are rare here iv havent got any adie about the difrance in size ,, could you guide me ? and IF the northstar TB it "da *shoot*" for what models are the right TB as i shall seartch for ?

L67 throttle body is 69mm diameter, Northstar is 75mm.

Which one will work?
1995-older: No

1996-99: Yes, can use either the 3800 MAS (might have to modify slightly) or the Northstar MAS.

2000+: Yes, but need a standalone MAS (such as the LS1 sensor).

great il think we mean the same as i call it massive airflow sensor and you spells it MAS but im used to call if MAF ?

It's the same but MAF is the most common in 3800 world.
