turbocharging 2.3 20V (7A type)

[Tom_]

Hi i wanna to asked you, if somebody have turbocharged 7A engine (2.3 20V) . Because in our country is too hard to find a good S2 car, so i thinking that i want turbochared this engine.

Thanks a lot

it has been done, in fact Carlos on here is doing this project right now

Depends low pressure turbo is an easy one, for the full blown thing it is a complete rebuild with custom pistons the works, but you will end up with a mega strong engine in the process.....

Oh yes, supercharge the thing!!!!!!

what about an eaton compressor?

.

Very popular conversion in the USA, go on the motorgeek.com site and also check out 034motorsport.com. for parts.

Error404 : Carlos? Has he got his project on Project Room?
Azman : i compared the low pressure turbo without changing pistons,conection rods,etc...
Skull23 : compressor is good,but the turbo is a turbo. Take ,that the engine 7A has his full own power from 4 000 rpm/min , so i think that the using the turbo will be better for the use full potentional of the engine...

Sry for my bad english

a 7a is a good staRT for FI.

basically a vw16v engine + 1 pot.

to do proper you need rods and pistons.

the most important part is the ECU. its all about fuel and air and timing. turbo is a turbo and turbos all do a similar job its all about compromise between top end and bottom end.

id go scats and wiseco's or JE.
tubular and a gt or a t3/t04e 57 or 60 trim with a stage 3 0.63 hotside.

stacked gaskets with arps will hold 400whp if the vw is anthing to go by but try t okeep torque below 350lbsft if you use the standard internals and 2-3 gaskets.

Just here...only a very slow head building project at the moment, collecting parts for the engine.

rods are same for s2 and 7a

i'm turbo'ing my 7a lump and fitting into my UR quattro, but i wasn't sure if crank journals were different size to s2 (ABY/3B etc). Is it just custom pistons for the bore increase that are needed?

rods crank are all the same just pistons are bigger

[Puglife]

solves my issues there then
Best get buying some heavy duty parts

carlos , nice looking project, i hope that you finished this project soon I want to go this same way in future,but now i must learned and save the money on it

which ECU do u use? Standalone or piggyback?Can you write a list what u all change?thx and good luck

so 7A rods,crank are same as a S2 ? really?
