pureboiracer 0 Report post Posted March 28, 2010 is it costly to get the 2.8 crank into the m20 block or is it a pretty simple job? Quote Share this post Link to post Share on other sites

c.robertson00 11 Report post Posted March 28, 2010 IIRC you need tha spacer for the oil seal on the front of the crank and the skirts on the pistons need to be trimmed down abit then be balanced Quote Share this post Link to post Share on other sites
1rotty 40 Report post Posted March 29, 2010 I discussed this possibility with Glenn a while back-can turn in to an expensive exercise to do properly Quote Share this post Link to post Share on other sites
APT 189 Report post Posted March 29, 2010 I gave Ray a call and it does look to be expensive especially if you cant build your own engine Quote Share this post Link to post Share on other sites
Mark 178 Report post Posted March 29, 2010 DCH Motorsport in Chch do a drive-in drive-out 2.8 conversion for $7000. That includes the fully reconned 2.8 M20 and ECU upgrade/tune. So yep, it's expensive unless you're awesome at rebuilding engines. Quote Share this post Link to post Share on other sites

HELLBM 1552 Report post Posted March 29, 2010 Cost my son about 1100-1200 to convert his M20B25 into a 2.8 stroker. All I donated was the crank and M20B20 rods. That included shortblock assembly by paramount engineering. Do your math around that and you come in comfortably under $2000. Pistons did not need to be altered. At $7000 the chch. place is making a shitload. Quote Share this post Link to post Share on other sites
Driftit 2078 Report post Posted March 29, 2010 It is a cheap and simple conversion. It is best to start with a 2.5 block. Then all you need is 2.8 crank with spacer and shortened (very easy) B25 pistons B20 Rods stock rings, bearings and anything else you want to do. 1.3 Motronic ECU and loom Reflash ECU by Gavin at Hi Velocity. So if you are starting with a 325. You don't need much. Once the crank is adjusted you just rebuild the motor as normal. Quote Share this post Link to post Share on other sites
