7A exhaust manifold

[Jas11n]

Hope some one can confirm something for me.
Got a chap over on Audifans with a throttle bodied 2.0 16v. We already know that the 16v engine is basically a 5 cylinder unit with a cylinder chopped off. We also know that the S2 exhaust and inlet manifolds will bolt to the 16v head once a runner has been chopped off (popular conversion in germany for the 16v engine). He's thinking on doing this in the near future, but first wants to see what it would be like to use the tubular manifold from a early 7A engine. Question is; is the stud pattern on the 7A head the same as the 20v turbo head ? ? Looking in the family album, it's hard to tell but it looks to be the same only with less studs.

Thanks

yup AFAIK it is since people have fitted RS2 EM's to 7A's before

Thanks Greg, I thought as much, just needed a second opinion

does he want a 7a tubular manifold?

i have two of them

Yes, 7A manifolds only use two studs per cyl, where as 3B and ABY manifolds use three or four.

Will! you have a PM dude

Mark! thanks for the picture matey, very much appreciated The guy doing this, along with Tim Cooper of QRSport are currently working together on a throttle body setup for the 7A engine, junking the Hitachi management and using a system called Megasquirt

as in five individual throttle body’s? ...tell me more? Are they planning to sell it as a kit?

The 7A to me always felt like a great engine strangled and trying to get out, I’m sure it has a lot more potential with a nice intake setup.

My long term plan is to fit an ABY (if i can ever find one ) but i would be interested if the price was reasonable. ....keep me posted as that sounds very interesting.

Yep, five individual throttle bodies. The same sort of setup he is already running on his 2.0 16v coupe with the megasquirt management system.
They say it's not going to be too difficult to do the same on the 7A. IIRC he used the throttle bodies off a Suzuki GSX-R1000. Not sure if they plan to do a kit, will ask Tim and Paul if they are and keep you updated.
Read his thread on the whole process of the build, here.
