Turbo II or Turbo IV?

[The Pope]

by the look of it I think I'd look at getting a ATP 3" swing valve, sends the exhaust off the end of the turbo, instead of aiming it directly at the rear frame.

Also consider a plenum, yeah more power and RPM range, but allows the throttle body to be mounted just as easy on the passenger side if you want, of aimed towards the drivers side. Instead of aiming towards the front of the car.

With the ATP you could also run a TBI header that drops the turbo down a bit, could make routing the exhaust nicer with the ATP and better for power. Then It may be a matter of one big U bend 3" pipe and run the 3" muffler right under the rear frame with the outlet on the drivers side.

Thanks,

I'll tell the shop (SRD) about these ideas. Any cheap power/economy gain is a good one.

the ATP is cheap, the others aren't really cheap. The header doesn't fit too well in the FWD cars but in your case would make it nicer. Most I've seen also have both T3 bolt types too. All three I mentioned would make boost basically instant as a bonus.

I'm probably going with a bigger aftermarket turbo, would that change anything you were mentioning.

Also, where can I find these parts?

No rush here, it might take a few months to get it running????

Thanks!

What about using the cross-drilled 87 TII engine with a Garrett GT turbo with its roller bearing design, it spools up quick, makes good power, and very reliable.

FWDperformance.com may have the TBI and the turbo and the ATP, if anything they come across a lot of different parts. The TBI header though is cast, longer lasting than a tube header. Otherwise I would watch the for sale section for a TBI header and turbo, FWD has a used good Turbonetics turbo FS in the FS section here.

The plenum though you'd need to get from GLHNSLHT2 here if he has anymore.

Being a nitch market parts are all over the place, can't go to summitracing and buy everything lol.

also if your going with bigger parts you should have FWDperformance do a computer for you.

The X1/9 is coming along now. I have ordered an engine from Forward Motion, and the current engine is partially mounted, with the shift linkage mocked up and working. It looks like I'll be able to fit a 3" exhaust without much problem. Time to buy a new AC compressor and try to find a heavy duty alternator. I'll also be having a both custom radiator and evaporator made, and also a custom water-to-air intercooler.

The guys at SRD are doing a good job so far!

My X1/9 now has 3 motor mounts on it, YAY! Still awaiting the engine from Forward Motion (Turbo II). The front suspension is on (K-Sport Coilovers) and the rear will be going on soon. Linkage is mocked up. Will be making a custom radiator and condenser soon, so that we can continue with the hybrid Dodge/Fiat AC. Hopefully I can find a Dodge cruise control system with all necessary parts from '87. One of the custom half shafts fits, but one is a bit too long and must be modified. Last, I hope to find a good super high output alternator to leave my electrical options open.

going to do an air/water intercooler setup?

[heckdave]

Yes, air to water intercooler. We'll probably take some air from the side of the car, but the challenge is to get enough air for all three (radiator, condenser, and intercooler), and keep the car looking relatively stock.
