i just got a 1990 DA rs clean in and out but it has 177000 miles on it the owner said it started to make alot of noise in the head and just park it for like 2 years now i pick it up but i want to turbo it but not spend to much money i would like to make over 250 hp now what parts do u guys think i should go for im going to shotpeed the stock rods and can i use the stock pistons or should i change them also i have good hook ups on dsm parts i was a former dsm owner of a 414 hp 1990 gsx so i know about parts and fab. thanks

You need to fix the noise problem first. After you fix the problem, do a compression test. You don't want to boost on a motor that will blow the minute you boost. While you have the motor tooken apart go ahead add some aftermarket pistons, add some arp rod bolts.

yes i know im going to rebuilt it i think its the rockers arms but dont know yet for sure thats why i was asking what parts do u think i should use for the rebuilt im going to built the bottom end somewhat like shotpeed the stock rods and micropolish the crank and balance it oh and arp bolt for the stock rod and head bolts i guess stock pistons and new rings i will be driving the car as my Daily driver like i said i would like to make over 250 hp and boost a little over 10 psi. thanks

I just tuned an b18b on 10 psi with a .53 compressor a/r and a .63 a/r and it made 260 on a pretty conservative map as far as timing is concerned on totally stock internals with 2 1/4 exhaust on a stock style muffler! Its all in the tuning my friend.

well i removed the valve cover i found out that one of the retainers in the intake valve on #3 cyl came off 2 broken rocker arms like in 2 cyl og timing belt as far as i know jump like 2 teeth on the intake side cam i removed the head and pistons have a little carbon but no piston damage no valve contact so the bottom end looks good so far going to removed the oil pan and taking the pistons and rods out what piston ring should i use and head gasket do u guys think i should use for turbo ho and i am going with arp head bolts like i said going with stock pistons and rods. thanks

I'd do a compression test before I took it apart to see how the bottom end was looking. Then I'd address the Head issue and when I put it back on I'd add some ARP head studs. Leave the bottom end alone, a stock LS bottom end is more than enough for the power you want to make, assuming compression is good.

hey thanks i bleedjdm i took the motor apart and putting new rod bearings and piston rings and arp head bolt but what headgasket do u think i should use cometic/stock/felpro/or what and water pump gsr pump or stock. thanks

stock head gasket if your sticking with the stock 81mm bore. Cosmetic if your going bigger. Just up grade to the gsr oil pump.

sorry guys i forgot yea its stock bore so stock head gasket and gsr oil pump then stock water pump i guess ?

use the ls water pump, gsr water pump has 22t. Use the ls gear where your oil pump is located.

hey thanks mp82 so get stock water pump and gsr oil pump and use ls oil pump gear do u guys know of any body that tunes ls turbo in california like in the san gabriel valley thats pretty good
