alex37211 Posted November 13, 2008 Share Posted November 13, 2008 If you start with a B18 motor, it would be safer. The b20 houses the weakest cylinder walls of any B-series motor. Block guard can't hurt, but the correct method would be sleeving the block (gets pricey). ARP rod bolts are a good idea too. Rod bolts are usually what break. Suspension? Yeah, if you have stock suspension, upgrade it. $400 or so should cover some decent struts and springs. But it's not necessary for the swap if that's what you mean. Dyno time and tune is like $300-$400 around here. Just to give you a rough idea. If you don't have the cash to have it professionally tuned, don't do it at all. Especially if you do go the B20 route. It only takes a little bit of detonation to crack those sleeves. I would have it towed to the tuning shop. You can do a lot of damage just driving it a few miles if it's not set up correctly.

chrisz232 Posted November 13, 2008 Author Share Posted November 13, 2008 okay cool. yea ive heard the blocks are weak. but i have also heard the produce tremendous power. cause my boys got hit and gone thru a t3/t4 turbo and now has the GT25R on it and never had a prob with the motor or the car. the suspension is what im worried about. i live about 10 miles from the shop im getting it tuned and dynoed at. i got another homeboy with a 93 rx-7 running 14 lbs untuned right now and he is pulling on 500 HP cobras. i mean granted its a rotary motor so its not as bad but... still... but yeah thanks anything else let me know.

Kastigir Posted November 13, 2008 Share Posted November 13, 2008 You can build a B20 block to handle boost well. All depends on what you're willing to spend. The CR of the B20 is perfect for boost though. Link to comment Share on other sites More sharing options...
