280 bhp ca 18det

[200sex]

Hi all i ve recently bought an s13 it s a last of the line m plate, and i was assured it had the lsd diff but how would i tell bar stripping it down? also i ideally want 280 brake from the engine for some high speed drifting action, will the standard internals cope with this? (ca18det) i ve already got a gt28r garret and wondered if i should uprate internals? any help much appreciated ta.

Jack the back of the car up and spin one of the wheels, if the other spins in the same direction you have an LSD

280bhp shouldn't be a problem with the right bits, but CA big ends are made of cheese, so a high quality oil, with an oil cooler, and oil temp gauge would be big on my list of prioritys..

yeah, what Phil said plus, if the engine is an unknown, I'd be inclined to check the bottom end and fit new bearings anyway just to be sure. They'll do that sort of power on stock internals okay but you'll want a good quality FMIC (not a volvo one or the like) and a stage 2 chip.

budget for an uprated radiator aswell if you can. im running about 270 on my CA and the temp does get quite high when drifting.

Stoofer, you got a thermo fan on yours or still got the engine driven one?

I reckon if the stock oil cooler was swapped for an external one that would help get the coolant temps down a bit too.

I still have the viscous one.

I have an external oil cooler which definately helps with the temperatures (I have a jap spec engine so it had no cooler at all), but the water still gets hot (stock radiator)

one of my turbo water feeds is leaking slightly too, so Im going to completely block them off - Im not sure this will have much effect on keeping water temps more reasonable, but it cant do any harm.

The way I see it with the turbo coolant pipes is, if removing them drops your coolant temperature then they are obviously doing a useful job of removing heat from the turbo. If it made no difference then you may as well remove them but there would be no advantage in doing so. I guess you could fit some kind of cooler like a heater matrix in the return coolant line from the turbo, maybe?

I reckon it's well worth fitting a thermo fan

 

[stoofer]

I see what you mean but the way I look at it is that the water cools the oil around the turbo which does the real job of cooling the turbo. my oil temps are fairly solid since the oil cooler went in, and should be more than enough to keep the turbo happy

I guess when I remove them Ill see what effect it has on oil and water. everythings worth a try, especially as it also fixes my leaking water problem while I try it

thanks guys i ll get those big ends sorted right away, is the standard lsd any good then?

I wonder if you could use the pump and cooler of the S13 diff to make an independant oil supply for the turbo? That would be great as it could continue running for a bit after you switched the engine off.

The standard LSD is a viscous one and it's not a lot of good for drifting really. If you can't get a plate one then a welded diff is the next best thing (unless it's a daily driver)

Its ok to start off with but eventually it will piss you off while drifting.

Are you being tempted to change yours then Steve? I thought you were one of the bigger fans of keeping to stock LSD. Infact I remember you saying youd never get a mechanical after hearing the noise Matts made.

Finally having my Nismo fitted next week anyway, so Ill soon know the difference for myself.

Cheers

Definately tempted. I think the uprated VLSD is the way I'd go, cheaper, no maintenance and no nasty noises.

I still think the stock LSD works well enough to get into drifting but I'm finding that although its fine for mid/highish speed turns it sucks when it comes to tighter stuff, I was having a mare with it at the Doricar day slalomy bit of the track. Doesnt help that my car isnt properly mapped yet and has some serious low end power issues i.e. there isnt any.

I agree, when it gets hot on tight tracks, you keep on having to explore where the lock is as it keeps on changing.
