Re:Qs about disco potato (gt28rs) on JDM B20a
 

I wouldn't worry about the sleeves as much as the rods/pistons. From what I know about those blocks, they are fairly strong. Unless you're planning on breaking new records I wouldn't worry about the sleeves, unless you really wanted to. A nice set of forged pistons and rods will give you plenty of strength. Where is sean88accord?

Re:Qs about disco potato (gt28rs) on JDM B20a
 

can i give a lil insight to the mans project?

lookie here ppl...im not an expert but ive studied these motors up and down and have built them alot...ive even helped convert 2 of them to vtec but i havent done it myself due to $$ issues...my 89 lude has an almost stock b20a5 in it...i turbocharged mine with 8psi and it runs great, after i learned how to tune it better...its closed deck...walls arent the thickest but i tell you the block will love up some 15psi all day every day if you just tune it pretty good...doesnt have to be top notch either...now i would recommend rods and pistons....pistons wont take more than 12 to 13 psi daily driven...and the rods dont like more than the same as the pistons...14psi at track racing only and then turn it back down to 12...the key to this is just get an safc apexi box and learn to tune it good...get a wideband O2 sensor and you will be fine...the sleeves are good to about 17psi with a really good tune...now if you wanna get ballsy ive seen 19psi stock sleeves but that thing had an immaculate tune and it was a track car only...i wouldnt ever think of more than 15psi stock sleeves with rods and pistons....just send it off to golden eagle if you wanna push more than that...and for 300hp...you will reach your goal with 15psi man...for all those who think the b20a motors suck....hell you should see tony baker on prelude power.com...its built to the gills, one BIG ass turbo with nitrous and alcohol injection....and his ---- screams power....i seen his video of when he was only at 14psi...he dumped the clutch in second gear at 6500rpms and was doing a 50mph burnout...that ---- was bitchin....dont hate on our motors just because we cant rev to 8k rpms safely on a stock motor....all i gotta say is we got torque...and its nice....

my buddy has his lude with 10psi and a pretty good tune, 236hp 243ft lbs of TORQUE...gotta love it....

louie

p.s. transmissions are easy to find...especially in my garage...i have 6...and one of them i just finished installing my ITR LSD into my 91 b21a1 trans with 1st,2nd,3rd gear from my 89 b20 with the 4th from the b21 trans and the 5th gear out of a GSR...i wonder how this thing will do for me...i guess ill wait and see.

cool guys thanks alot. yes im planning on getting some new pistons and rods. so the disco potato would be the better choice for what i want. Ill check the fuel managment forum so please done haze me but I thought the Apexi Safc was only good for like 9 psi. ive already got one and the hks evc 4. I was under the inpression for anything over 10 psi or so id have t run standalone and not a hack. I plan on having everything tuned on the dyno by a pro thats not me ;D. Im good by the seat of the pants but thats about it

uncle lois if i found the gearing on the 3geez website would you mind looking at it too seee if its good or not the way it sits for like auto crossing and some street stuff. I know the b16 diff from quaife fits in it.
