i installed a GTX35R turbo from rx7store but ran into a little issue, the turbo seem to be touching the lower intake manifold... the turbo manifold is tight and i hope there no exhaust leak but i can't even put a paper between the two...

does any one having else having this same issue with this Kit? also, will i be ok leaving it rub like this?

 

Did you buy this turbo to upgrade an existing single kit or was this a full gtx35 kit including the manifold? If it was a full kit I would contact rx7store and have them replace it with a manifold that fits better...

When the engine torques back and forth during hard acceleration and shifts it could put a lot more stress on the manifold if its being pressed against the engine and potentially crack it... Or worse off your floorboard could fall off for no apparent reason

 

i got the entire kit from them, sad that i just got the manifold coated

 

Got a GT35R kit from them, and I have the same problem. Mine's not as bad, I got 1-2mm but still. We are trying to find a way to make it work, only way seems to make a spacer between the block and the manifold, or a block between the manifold and turbo. Definitely less then ideal, we also considered grinding some off the intake manifold and turbo housing to get room for a heat shield in between. My local rotary guru told me that's got to be fixed before I drive the car, otherwise it could heat that intake runner enough to pre-ignite.. not cool.

 

They must have changed their manifold design, my kit from a few years ago didn't have that problem. Looks like the turbo sits further forward than before. Also, i would be asking for my money back or a proper fitting manifold, installing spacers or grinding perfectly good parts is unacceptable.

 

I had that same problem but I thought it was because I was running an Excessive LIM. I had to grind down the manifold and coated both the upper manifold and turbine housing and then put a heat shield on the turbo. I have since switched from a 1.06 to .82 and have more clearance.

 

That is strange. I haven't had any complaints or issues on the standard gt35r kit or any of our other turbos. Give me a call on Monday.

Thanks

 

Nice. You now have an amazing heater just heating away at the air passing through that manifold lol

 

Definitely something that needs to be fixed before driving. It is always a challenge cramming a huge turbo into such a small space, but there does need to be some room for isolation of extreme temperatures. Looks like that turbo setup will be great once you can get this part taken care of!

 

Sometimes cars that have suffered accidents can have these fitment issues due to the frame being just a bit off. Just a thought.

 

im having the exact same problem,

i bought a exhaust flange to put between the manifold and the housings..

look

but now it´s hitting the other side, so i took it to a machine shop and they are shaving a few mm from it to make it fit

 

Frame damage wouldn't have any effect on this issue, the only thing that determines the location of the turbo in relation to the motor is the manifold.

 

why dont you heat the manifold and bend it back a little

 

Looks like the issue is coming from GTX35R. I'm going to mount a kit on a block tomorrow and see what's going on. The standard GT35r fits fine.

 

If you spend the money for a full turbo kit from a "reputable shop" then you shouldn't need to "fix" the kit in order to make it work.

You need to "fix" ebay products to make them fit because you get what you pay for..

 

None of this kit is eBay so thanks for input. I sold around 75 of these kits last year and this is the first I have had any issues. I will fix the issue for the couple that are having a problem.

 

any news?

 

definitely not good to leave it as is, the snail will heat that front rotor charge air in that front chamber a bit.

 

I cant get to it until tomorrow but will post something after I do. I can easily modify the manifold to correct the issue but want to find out why its hitting first.

 

i know its not always feasible/possible, but ideally each turbo of each variation should be test-fit at least once on the kit, its obviously not safe to assume that a new version is going to have the exact same dimensions. sometimes even the manufacturer paperwork says the dimensions are the same, but in reality they are not, theyre just too lazy to reprint brochures etc.

i think we can all agree that what separates a good company from a bad one is how well they respond to an issue and what kind of support they provide. jason is jumping right on the issue and providing ongoing dialog right here on the forum for all to see, and it sounds like hes going resolve the issue quickly. thats a huge plus IMO. there are way too many companies out there that hardly even answer an email regarding a faulty product, let alone participate in forums and resolve issues.

 

I agree with this about rx7store.com. I was trying to get a power fc for my car a while back (didn't work out) and rx7store was great. In fact, I think I talked to Jason a few times and he was really easy to work with.

 

Thanks for the support.

I called a couple customers that recently got the standard GT35R kit from me and everything fit fine. So its either the GTX version that is the issue or I got a couple of manifolds that were off when built. I will know more tomorrow.

 

Test fitted a couple of turbos today and they fit without touching but didn't have a GTX turbo here to try. It looks like the issue is the exhaust on the GTX. I will be contacting the couple of people having issues and resolve the problem. In the future I'm going to modify the manifolds to bring the turbo out from the LIM.

 

so finally got around to finish this single turbo project... Jason from RX7store.net did redo my manifold and now i have 1 inch on each side... i do give them prob for always picking up my calls and taking care of the issue.

new issue that i have... the turbo drain can't sit straight down because it hit the turbo housing... as you can see in the picture the oil feed is about 50 degree... do you guys think that this is ok ? will it hurt the turbo?

thanks for your input...

 

IIRC you want to be within 15 degrees of vertical
