Hello everyone. Hope all is well. So, I have a decision to make. Currently I have TA49 in my car. All mods done. Just picked up a set of "Champion Irons." 212/212 flat Comp Cam in the car as well. Husek 3021 convertor. upgraded fuel pump, hot wire, headers, downpipe, 62mm T.B., 42lb injectors with 93 oct. chip, [T.T.] "Dutt Neck" S.L.I.C., Engine, trans. rebuilt, [but not for 11 seconds and quicker!] Here is my question. I have an opportunity to buy a brand-new Precision 6262 B.B. turbo. By the way, I'm the guy that does not use "alcohol" yet! Running 17lbs of boost on 93 octane. If I were to swap out the 49 for the 62, what would I need to do in order for that turbo to work like it's supposed to? Assuming I have trans. built for more power and install "Alky-control" set-up so I can up the boost. Besides a different tune, which would include a different chip. Would I need say bigger injectors? Larger intercooler? How would the car respond to larger turbo? Would it spool like the 49 because of the "ball Bearing" design? Is that the right convertor? Please, your input is important. I do not want the car to be a dog around town! Thanks very much...
To answer your ? concerning modifications require if you upgrade from a TA49 to 6262 BB turbo- there are few changes required for a 6262 BB turbo in-order obtain reliability and efficiency of the turbo swap.
1. Every Turbo requires its own specific combination of bolt on component in-order to obtain the best efficiency of a combo.
2. The 6262 BB turbo requires a loser than stock torque convertor somewhere around 3000-3200 stall to obtain the best efficiency/performance. Dave Husek or PTC can help you obtain a good TQ.
3. Also the fueling system requires at least a 340 LB/hour fuel pump and hot wire kit to supply ample fuel for the turbo.
4. Need to upgrade from a stock intercooler to reduce ambient air temp due a higher volume of compressed air entering the engine.
5. I recommend at least 60 to 80 lbs/hour injectors with an Alky chip tune or an ECU GN for a street car.
6. Your 212/212 camshaft and champion ported cylinder heads are a perfect match for that turbo.
7. Also- if your stock ignition module/coil is not working 100%- it might need replacing with a TR6 module/coil due to the demand for higher energy ignition spark need.
8. As you mentioned in your thread- a more robust transmission will definitely be required for that addition power- Janis Transmission or Dave Husek can assist you with that issue.
9. The most important thing required with any combo is- the Turbo/Camshaft/TQ/Tune/ Intercooler/Engine compression must match in-order to obtain the best performance and efficiency. Without that your wasting your money and time.
10. Also if your stock headers is cracked or leaking- dont weld them up. Get rid of them and purchase a set of TA performance headers.
11. IMO these are the minimum required things to do in-order to have the most success with your combination. Good luck my friend.
