Any suggestions?
First off the car was suppose to stay N/A, but decided to get it turbo'd. I've bought turbo manifolds and plan on installing a T60-1 turbo. I also plan on staying at 6psi. The engine is somewhat modified as you can see in the sig. However im still retaining a Remanufactured fuel pump, SVO 19# injectors and Holley AFPR. I plan on installing the turbo kit somewhat next month when weather is great. I've also done extensive searching in this forum. However i was hoping to get any other ideas from those who are interested in helping. I've heard about the 7749 swap. This is a syclone or typhoon ECM correct? Are they puchased used? If so where? Could i just have my factory prom Burned and maybe increase my injectors? I'd like to stay w/ my MAF system. Im not really too familiar or in tune w/ computers,ECM's or upgrades so if you could be specfic that'd be great. Any info or suggestions would be appreciated. thanks

Wow, I dont' know where to start. You need to do some serious research before you take on a turbo project.
The 19 lb/hr injectors will only feed about 3 of your cylinders once you put boost to it. You need bigger much bigger.
The 7749 is a good swap, because it can actually see boost, unlike your stock ecm.
Keeping the MAF is not going to happen with the 749.
You can get this ecm either used on ebay, or new from a parts store.
Most importantly, "getting your prom burned" isn't going to cut it. It won't even get your car out of the driveway. It's going to take 100's of chips to tune perfectly. Don't let this scare you, a 100 chips goes fast when your doing it DIY. Thats the key with any nasty setup, hands on tuning is the only way to go. Some one 1,000's of miles away isn't going to have a clue as to what your engine needs. I suggest you learn prom tuning on the motor before you jump into forced induction, this may postpone your turbo install to later this summer. This may not be what you want to hear but if you go ahead and just slap some turbo's on your ride your gonna mess somthin up bad, like your gonna need a box to take your engine home in.

Thanks for the heads up. I was afraid of that. I was hoping it'd be somewhat an easy installation, Just fix and go i guess. So to stick w/ the 7749 i'd have to go w/ speed density which is another conversion. I should of done my research before the project as you said. Guess i should hit the books. thank you sir`
