Hey, im trying to figure out what (if anything) is wrong with my old r32

Compared to the corolla i'm driving at the moment it's quick, but compared to almost everything else it's slow.

It's a R32 GTS-T with a hi flow cat, 3" exhaust with split dump, walbro fuel pump, R34 turbo, the ecu has been remapped, and it's running 14 psi. it got 163rwkw on a cold night (before split dump and cat) (133rwkw before 34 turbo and remap)

As an example, an s13 with a totally stock rb20, the only mod being a cat back, absolutely slaughters the r32 (i know it's about 100 kilo's lighter)

Anything with the letters SS (anything at all, including VN SS's) leaves it for dead, vl turboes laugh at it and swifts, gti's protons and tx3's give it a good run for it's money (which is about 5k more than most of the afore mentioned), all on the drag strip of course.

What i'm trying to figure out is whether this is because of A) a bad tune, B) a dead engine C) a dead clutch

I have had someone say before that the tune was a bit weird, so it is possibly this.. The tune was done before a split dump and a hi flow cat was put on, does anyone think the tune could be slowing it down this much?

Dead engine i'm too scared to check as it's not my car anymore and if it's down on compression i will feel guilty and probably buy him a new one.

The clutch is going i know for a fact, and it IS the standard one. Slam shifts can result in free revving (as in 7k rpm in 3rd while only going about 70kph) but will this seriously hamper performance in gear? For example if 2nd gear is slowly selected then the boot is put on, the clutch will be properly engaged correct?, or is there a chance that it could still be slipping and that be where im losing power?

I've actually posted this before ages ago when i was the owner, ended up deciding it was just the car, but now i am interested too hear any suggestions (after getting in that little s13 and feeling how much faster it is).

thx

clutch is slipping badly.. have it replaced..

the power figures tell u that it is making power and the engine is not dead (unless sumthin has happened recently)

so it has to be driveline related, gearbox, diff, etc. I am guessing its the clutch by reading ur post

Ah, ok i just wasn't sure if it could still be slipping while in gear (i.e. whilst in second gear, cruising). It fries the tyres coming onto boost in 1st too so i wasn't sure whether the clutch would/could be a problem in 1st. Guess it's time to look for a groupbuy on an exidy single plate or something..

MODS:

Can this get moved to the clutch/drivetrain/gearbox area, as i have a clutch related question and it will save me having to write up a new topic

yeah mate get your clutch changed. its definitely slipping. as for frying the tyres on boost in 1st, all that means is that the clutch is still good for 1st gear and as yet to slip in first. but by the sounds of it...it wont be too long now before you will start to experience slipping in first.

my clutch was slipping badly. firstly it would slip in 5th, 4th, 3rd then finally it started to slip in first, in which case i was pretty much crawling along. mine slipped even in when the car was in gear. changed the clutch to see it was worn down to the rivets. NOT good!

hope that helps!

goodluck mate,

:P

    • I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!  
    • Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
    • I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.
    • I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?
    • I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
