Turbo Question

[mr supra]

So a friend of mine has a set of stock turbos off of a MK4. He only wants $300 for them. I have a MK3. I was wondering if they would work well on my 7M. If so should I do a twin or single turbo set up? I'm not looking for massive horsepower. All I want is something a little more fun to cruise.

The simple answer is no. If all you want is a small bump in power then get a boost controller and piggy back fuel controller. When you do your fuel tune you should use a wide band AFR monitor to do the job. The stock narrow band isn't sensetive enough for tuning. You can push things up a bit, say 12-14 psi, and be ok. Make sure that you get an after market boost gauge to keep an eye on things. The stock one isn't up to the job.

Thanks for the advice. All that stuff wuold be great if I had a turbo already. Sorry, forgot to mention that this is going to be on a 7MGE. If I'm were to turbo my non-turbo would these CT-12 turbos would well as single or sequential, or would using a stock CT-26 be better. I also found a garret T-25 ball bearing turbo for Ithink $600 or $700. I don't have a lot of money, but I do have time, patience, another car to drive, and a friend that is an awesome welder and fabricator. Any help or insight on these turbos would be great.

Just swap in a 7MGTE and be done with it. They run about $900.

Don't crank up the pressure too high on that set up. The 7MGE has higher compression pistons that the 7MGTE, and will not be happy if you do.
