Hi guys

Some of your superior wisdom needed for this uk r33 owner.

I have a t04e turbo ar50 (ext gated) and an hks cast manifold to fit to my 33gtst but understand that the compressor housing fouls on the engine mount, if true how do you guys get over this problem. Do you use nismo mounts or aftermarket fabricated ones or cut the sh*t out of the original lol.

Any advice appreciated

cheers craig

Someone please reply with first hand experience, I want to do a similar job witha TO4e on an R33 GTS-t, using the same manifold. What turbo did HKS intend this cast manifold to be used for when it was new, anyone know? I also have an RB26 version of this same manifold, anyone have this and know *FOR A FACT* what turbo clears OK on an R33 GTR? Cheers.

Really need some pics to make the problem obvious to all . That TO4E of yours , if its using a TO4 hot side the housings tend to move the centre line of the turbo away from the manifold and I imagine closer to the engine mount . If you look closely at HKS's GT30 style turbine housings the mounting flange extention is very short (if you equate housings to snails I mean the bit where he'd stick his head out if he was born in a foundry) and the turbine outlet smaller and more compact that TO4 housings .

That manifold would have been intended for GT3037's , GT3040's and GT3240's though if the external gate mount was blank plated a 2530 or any T3 flanged turbo may fit .

Yeah, need some pics of it all and how it sits.

I think the HKS one sits higher then the GTS-R... but pics will tell that story.

I had a GT30 .7A/R covered turbo low mounted using a GTS-R manifold on the RB25, and thats inclusing squeezing an 45mm turbosmart ext gate down there aswell.

I was very damn close to the engine mount (comp cover), but there was just enough room

Then once the gate was put in... no room ;)

Thanks for he replies guys. As far as i know it was a kit sold to suit the rb20/25 ,don't know if the mounts on a rb20 are any different. Will try and get some pics from a guy who test fitted one and told me of the problem.

cheers

I fitted a t300s low mount hks kit to my rb25 r32. It required some minor mangling of the engine mount (it's an rb20 mount though). However i have also seen a t04e mounted on an rb20 that only required the removal of the sheet metal piece from between the top of the rubber mount and the bottom of the engine mount (if that makes any sense?) The comp cover of the t04e is a .50 from memory and is a fair bit smaller.

The r33 uses a different mount to the 32 and appears to be a bit thinner and they mount flat at the base which should put them well away from the compressor inlet on a t04e kit.

Ive added a pic of the t300s and the slightly bent r32 engine mount to show how close it is but in all honesty i dont think you will have a major problem with fitting the t04e, also considering it is only a 2.5 inlet as opposed to the 4 inch on mine.

dont mean to hi jack this thread but ive just bought one of these hks low mount manifolds and i intend fitting it to a r33 rb25 with gt30 , a/r 70 comp compressor cover with rb25 internal wastegate exhaust housing am i going to have problems clearing engine mount as well????

I suspect, short of someone fitting this EXACT same turbo, that you will have to offer it up and see. i am becoming resigned to doing the same myself, and maybe having to make a new engine mount that clears it.

      Welp, good to know. Will have to wait awhile until steady hands with drills and taps are available. In other news, these just arrived! I will weigh them for posterity.

      100% the factory sender is tapered, that is how it seals (well, that and teflon paste or tape)

      Thanks folks - I've saved a few links and I'll have to think of potential cable/adapters/buying fittings. First step will be seeing if I can turn the curren abortion of a port into something usable, then get all BSPT'y on it. I did attempt to look at the OEM sender male end to see if it IS tapered because as mentioned you should be able to tell by looking at it... well, I don't know if I can. If I had to guess it looks like *maybe* 0.25 of a mm skinnier at the bottom of the thread compared to where the thread starts. So if it is tapered it's pretty slight - Or all the examples of BSPT vs BSPP are exaggerated for effect in their taper size.

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
