    Have not seen or looked over the car yet but he says it's rust free and already has track brakes and suspension. Will be seeing the car next weekend.

      Steering linkage in the way for any bottom mount turbo manifold.  You can squeek 175rwhp out of a m20 n/a with a ton of bolt ons and megasquirt.

      Well that's a bummer. Was going to give you a call as I think for the money a sarge 1 kit would have been the way to go

        Also he does just does track days with it no competitive racing. He goes to the normal track around so small and big. Don't know if he uses it on the street or not though.

            I vote turbo! with that budget you could have an incredibly reliable setup, and even 300whp would be pretty insane in a 2002, and 300whp can be VERY reliable on an m20 on pump gas. very simple and at that power level nearly instant spool with the right parts.

              Problem being there is no bolt on kits for the 2002 which would make things more difficult and since it's only 2 of us at the shop we don't have enough man power to do a full on custom build and still keep up with the other customer work since we only work weekends

                A properly designed ITB setup will net some real, tangible horsepower gains. Packaging could be an issue though, as the runners tend to be pretty long when they're done correctly. The looks and the sound thoungh.... :eyesrollingbackintheheadfrothingatthemouthsmiley

                  It's most likely looking like it's going to be a 2.9L stroker with possible ITB's pending some tuning availability.

                    If the customer is a goofball and doesnt mind coming in periodicly for a re-tune and linkage adjustment then ITBs could be lucrative, otherwise it could be a hassle to the customer to not have it running consistently due to the finnicky nature of Alpha-N tuning.

                    The money spent on ITBs could certainly go towards the higher CR pistons and larger cam that will be needed.

                    The Metric Mechanic pistons have valve reliefs that make the M20 a non-interference engine, even while increasing the compression ratio which would be a huge selling point if I were a customer.

                      Very true on the ITB's. I'm still weighing my options. He saw a s50 2002 online and wanted to do that but after looking it seems like there is so much fabrication involved when doing that which I can not offer. Boy I wish this was a e30 at least. I don't think it's worth sticking $6k into it for a 2.9L stoker and ported head for at most 190whp.

                        24v swaps are boring. Get creative!

                        Oh wait, this is reality, not my personal fantasy land. Sorry.

                        Would get some good reactions when you popped the hood, and the transaxle would keep the weight distribution where you want it. 😃 Someday, when I have a nice shop and a crap-load of money and free time...
