Hey this is my first post and I tried a search too, bear with me.

I have a few questions acually, BTW I have a 91 CRX si

First, before you turbo a B16/B18 what should you do to "bulletproof" the engine so that it can handel boost. Also what about bore? Also what PSI should I run if i still want the car to be a daily driver?

Second, I am going to swap the stock CRX engine out and put in either a B16A or a B18B engine. I don't know which is better but I plan on FI and the B18B has those low compression rates. I was just wondering what some of you pro's thought.

Third, I propably will anyways, but is it necessary to buy new axles, Shift linkages, and motor mounts?

I know some of these question might get asked a lot, but not in one place right?

 

You have no idea how many times this has been covered. I suggest you refrain from posting and use the search button.


Almost every question can be answered here:

the easiest way to bullet proof a engine, is engine management and tuning.

For low boost (less than 8) pair it with good reliable parts and good tuning and your motor will be bulletproof.

For high boost, there are many factors, pistons, rods, bearings, sleeves, headwork, TUNING etc...

You need to search, do alot of reading and alot less posting,

Either swap is fine, i wouldnt say one is better than the other.

 

just go to http://www.importbuilders.com They bulletproof a lot of engines. I think you need to read more about turbos before you get into this though.

 

what they sed,byt it doesnt really matter what motor comes with low compression stock because if your going to build it just get a set of low comp pistons.persoanlly i would go with the b16, check out the forced induction forum they can help out a lot.good luck

There's no way to "bulletproof" an engine.

The best you can do is prevent it from happening by:
1. proper tuning
2. strengten the block to handle higher boost
3. upgrade the cylinder head parts such as valvetrain to handle high rpm high boost. to prevent valvefloat with weaker valvesprings.


There's plenty of posts answering this type of questions. You just have to stay awhile on HT and absorb the information being shared here.

If you have any other questions specifically, feel free to PM or email me regarding race engine setups.
