hi, i saw one of your posts and notice that you have a 240 with the silvia engine swap. i have found a 1990 240 for $1k. it is in really good condition and has a clean record. i was considering buying it and then doing the sr20det swap. red or black top im not sure. but i was wondering if YOU actually did it, or bought it installed. if you did it, what where some of the problems and tips for doing it. or if you at least have help in getting the front clip of a silvia. anything would be extrememly helpful. thank you.

86.5mm, you'll need it bored by 0.5mm. Depending on the amount of boost you're running, you'll have to gap the rings differently. I had the specs in my rebuild notes for the CP's which I'll find shortly.

The Eagle rods may not have been necessary, the stock rods are quite strong. If you are reusing the stock main bolts, measure them first. If they're within spec, you're fine. If you're switching to ARP studs, you'll need to check the line bore on the block. If you do not have a bore gauge, go to a machinist, this is over your head. (Note: ARP's main studs for the SR20DE are too long on the #4 and 5 studs on the exhaust side. You will need to have them ground down)

Since you've already purchased bearings, I probably shouldn't bring this up, but you could have gotten your crank polished. Depending on how much material is taken off during polishing, you may need to resize your bearings.

Note: Remember to lube the rings and the cylinders prior to assembly, it'll make your life easier. Try using Redline's assembly lube for the journals on the crank, but it's a bit thick for the pistons, so I suggest using motor oil there. Also if you're in this far, make sure you've got that front timing chain oil jet. It's very important.

for OMG im sideways. I did the motor myself with a friend helping out. pretty everything is drop right in all you need is the power steering lines for the pump unless if you dont want power steering :p. anyways feel free to ask more questions.

my goal is 350wrhp to 400wrhp and i want my motor to handle it on pump gas safely. Will the stock rods handle that much hp or should i just go with eagle rods? i haven't purchase the rods yet but i do got the pistons. Do you think it'll be easier if i give it to a shop to do it? thats what i think too but my budget is short so i asking for informations and see if i can do it myself thank you.

The stock rods given that you didn't spin a bearing on them or some other outrageous stuff happen to them, the eagle rods are a waste of money. Get some ARP rod bolts and get the diameters checked. My ARP rod bolts changed the diameters so it was more oval than circular.

If you have not sized piston rings before, if you have not sized bearings, don't have a line bore gauge, forget it. Take it to a machinist.

i guess i'll just bring it to a shop since i have to bored my sleeve .5mm so thanks for all you help. just have to wait for 2 more months so i get all the cash. THANK YOU 180FAN
