Twin turbo 418ci
I am about to start a rebuild on my new motor and I was thinking about doing a twin turbo setup. At this point in time nothing has been decided yet and I am just after some good advice before I commit my self to the project. The motor will be going into an 1993 EB Fairmont and will be replacing my 302. This is a quick rundown on some of the parts that I am planing on using.
351 Windsor D4 block
Eagle Stroker Crank
Probe forgies (Was going to use JE but they don't have low comp pistons.
Total Seal Rings
1/2" Main Girdle with studs
AFR 225 Heads With Stainless Steel Race Valves
Hydraulic Roller Cam - Cam grind not decided yet but it will be mild
Compression will be around 9:1
Trick Flow R Intake Manifold With suitable injectors, fuel pump and maybe Vortech Fuel Rails if needed.
Autronic Engine Management
The turbos that I would like to use are Garett GT30 or GT35 units
The questions that I have are:
A. Is there any cutting of metal involved in the engine bay (eg shocker towers) or will the turbos fit without the engine bay modifications. I know this might be a dumb question but I really don't know how big or small these turbo units are since all the quotes and specs were over the phone or by email.
B. So far the best price I can get the turbos for is around $2600 each and I was wondering if this is a good price and if there is someone that can do a better deal preferably in Melbourne.
C. Anyone in Melbourne that can fabricate the exhaust manifold for me...I am more after quality and reasonable price then hunting for bargains and dodgy workmanship. I've read somewhere that someone has used 1966/67 mustang reverse mounted log style exhaust with a custom fitting to accommodate the turbos. Any suggestions?
D. Where is a good location for the turbos. I was thinking about removing the standard intake box and moving the battery to the boot and mounting the turbos there.
Money is and isn't an issue (I am willing to pay any reasonable price) as I will be doing this in stages since I am in no rush. I want to use all new parts so I don't really want to be tracking second hand turbos at the wreckers or importers...etc. The motor will be built first then I will do the turbos and intercooler followed by engine management, injectors, fuel pump(s) etc.
I am open to suggestions and any good and valuable advice will be appreciated. I would like to know if all the trouble will be worth it or not before I begin this project. At this point in time I don't really care about what bhp the motor will make and I have a self imposed bhp limit of 700bhp and 6000rpm maximum because that's as much as the stock block will take but in future If I get addicted to the power I might upgrade to Dart or SVO block.
Sorry about the big post.
