rb20det silvia

[sluggerS13]

hey all, i'm currently doing the rb20det conversion in my silvia, so i thought i would sign up here to get some tech advice and mod advice. it's being transplanted in the second week of september down in newcastle (jt autogas) so i'll probably be cruising the streets for a while before i head off home. look for the black beaten up silvia bloody trees. so are there any problems that anyone has experienced with the rb20 (out of an r32)? anyway, i'll let you all know when it's done and how it feels.

cs_180 might have some ideas, he's just done this swap recently

[Fro-Daddy]

ive heard of really really bad overheating problems, and thats in winter!! better suss it out a lil more aye...i personally think the sr20 is a better option, up to u in the end though

[CS_180]

the over heating problem is all about the way they put it in and set it up.........

i havent had any probs yet with over heating

[omp]

Yea rumours........ I had to get a new thermostat in mine as it took to long to warm up! Never had any drama's, allthough I upgraded the R32 radiator with a thicker core so that may have something to do with it.

[SmItLeR]

i havtn had any overheating probs in mine - although RB25 are known for awsome cooling

basically - have 2 thermo's and you should be fine...thast saying that everything else is in tac i.e thermostat, flushed radiator etc

[neil_se]

No problems with mine either. I've got 2 thermos, removed the aircon and spaced the rear of the bonnet.

[SmItLeR]

yeh spacing of the bonnet helps alot with cooling

[neil_se]

I had to do it to get the engine to fit, the cooling is a bonus

[SmItLeR]

yeh same... pits dont like it but i managed to get it all licensed

[sluggerS13]

it's getting closer, i'm so excited. what is the standard psi? what power does it put at the wheels? cheers guys

[Minorci]

std psi is about 7 i think, get around 120-140... i was putting out 155 at the wheels on 10psi with a semi melted number 6 piston ... btw.. DONT BUY PARTS FROM NISSAN OZ.. seriously..they are ****ing me around, might be waiting another 3 months for my pistons... going forgies now.. hopefully.. will be finding out monday.

R32 wastegate can is 10psi

[rhysRB20]

Use a VL radiator! , I did and never had a problem (only one 10" thermo in the FRONT of the radiator aswell)

VL heavy duty radator (although fairly weighty) fits straight in under the s13 bonnet and th holes line up with ur RB20 motor as well.

[sluggerS13]

Ii'm getting a half cut, so the r32 radiator will be included. this should be sufficient, wouldn't it? one of my mates just got a gfb boost controller and turned it up all they way, he said it's running 15psi, i don't know if he's shitting me as i havn't seen it yet. this can't be to good for his stock as a rock rb can it.

[rhysRB20]

I don't think ur supposed to boost stock turbs (with stock cooler) past around 12-13 psi, correct me if i'm wrong anyone!

I'ts only matter of time before his exaust wheel gets spat into his cat converter!! if not that, detonation will kill his block

*shrugs* Some People need to learn the hard way

stock r32 radiator should be fine, just use 2 10" thermos on the back of the radiator (sucking towards engine of course!)

I was going to use the r32 one but you have to cut the bits of plastic at the bottom of it to make it fit, when i did this i cut it too close to the radiator and it leaked grrrr

I heard about VL ones so i went ahead and just got one of them for $100 from *Common*adore wreckers
