h22a7 swap in my prelude type S

Dennis van dijk · Post by **Dennis van dijk** » Tue May 17, 2016 1:09 pm

In the time my type S block is going to be rebuild i want to swap a h22a7 in my 5th gen type S

How hard is it to rewire the a7 in the prelude

I want to use the type S ecu because of the immobilizer(type S doesnt have it)

Who has the info for me

Kind regards

It should be plug and play so long as you are using a gearbox that is not the Type-S gearbox. You will need to use the Type-S distributor (and maybe the VTEC solenoid), other than that all the other parts should be the same.

Got my type S wiring on the block

Difference

Iacv is differend --- rosko racing adapter
Egr valve has other plug (swap mine)

Temp sensor on the head (take it of the type S engine)

Feed line fuel on the rail on the other side

Guys any suggestions?

Why not use the Type-S intake manifold and side step these issues? You will be using the Type-S ECU anyway.

I am surprised to hear you say that the temp sensor is different, is that the temp gauge sensor or ECU temp sensor? Every H22 I have used has the same sensors for both.

Its the 2 wire on

Type S has a round one and the a7 a square one

But it was a test to check the difference

Yes the temps sensors are different. We're different on mine.

Ok than it isnt strage

Some guy here told me the type S intake wouldnt work on the h22a7 because of the extra holes above the injectors

Took it of today

Like i see it its a vent for the iacv

But the type S system works different so it will work

But what gasket do i need

H22a or h22a7 or it doesnt matter ???

I use the type S mani now

The type s isn't any different to other preludes on the intake manifold. I used both a 4th and 5th gen on mine as well as the stock type s. They were all the same apart from the injector sliders.

Came top put the h22a7 intake on and the two sensors would fit after I modified everything else.

I get the type S one on it

Can i get a normal gasket for the intake

And how about the vtec solenoind the a7 has the extra sensor

Get the a7 or type S in it
