Recommended Turbo upgrades
 

I'm looking for a reliable upgrade that bolts up to stock manifold. Anyone have any ideas. I have the old turbo out, just waiting to hear from people who actually have Rotaries and know what they're talking about...People like you. For an '88 Anniversary Edition RX-7
THanks in advance

stock turbo is compatible with T3/4 parts. this means that with minor modifications, you can bolt up a T04B cold side to the factory center cartridge. It is common to swap the front side for a 60-1 hifi or H-trim T04B and keep stock turbine wheel and housing, which gives you a fast spooling 300whp. While its out, you will want to port the wastegate also, S4 especially. search, there are lots of threads on it

Thanks for the quick response. Forgive me, but I'm new to this. The new turbo that I bought does not match the bolt pattern to the manifold. How do I over come this?

Piggers - The first questions you need to answer with any turbo upgrade is what are your goals for it, and what is your budget? That will help bound the solution for you. There's more to this than just bolting on a bigger turbo - it won't take long before you need to deal with fuel and engine control issues as well.

I went down the upgrade path last winter, when it was time to replace the worn out stock turbo in my '89T2. The following threads covered the questions I had and responses from this forum, might be worth reading thru:

Bottom line, I installed a BNR Stage 1 turbo, upgraded all 4 fuel injectors with Bosch 720cc injectors, upgraded the fuel pump with a Nippon Denso pump from the mid-90's Supra twin turbo (drop in fit), and sent out the stock ECU for the Rtek 2.x upgrade, which mods the ECU to provide enough fuel/air & spark tunability for my modest goals. Also upgraded my stock radiator to a Koyo AL part to increase cooling capacity (upgraded turbo = more heat).

Both types of stock FC turbo turbos are proprietary bolt patterns / flanges.
To makes any other turbo fit, you need to make a custom adapter.

I can vouch for the bnr turbo being a good idea. i have a stage 3 and my car will move. I love it, and it screams at only 10 lbs right now. bolts right up. and bryan at bnr is a really good guy.
