Hello! I have a 2013 Chevy Cruze LT 1.4L turbo, I want to do a camshaft upgrade from zzp but I’m worried I’m going to mess up the timing, is there a way to do this without taking off the timing chain or having to reset the entire timing? What I’m trying to say is can I slide the cams out while keeping tension on the chain (zip tie it to something) then slide the new ones in?

You don't really want to be messing with the camshafts if you don't know how to time the engine.

That being said, what your wondering is possible with the proper tools and care. ZZP recommends upgrading valve springs as well. They told me that the stock springs will likely bind with the extended duration and lift of the cam.

I'm in the process of a rebuild and I upgraded the valvetrain with the head off of the car.

 

[David184]

Say I would try to upgrade anyways because I do understand the risk being it is an interference engine and all. I would buy the proper timing tools and the valve springs I did not know about Thankyou for that, how would I go about this?

 

[JLL]

I recommend buying a service manual and reading through it. That's good to be the easiest way to understand what's involved.

BTW the LUJ/LUV is not an interference engine, at least not with the stock cams and internals combination.

 

[David184]

Really? Could have sworn I read somewhere it is an interference engine. Have not read through a service manual but I have watched videos on people doing but they all had the engine out, will read up on a service manual Thankyou

Your welcome. The 1.4L LUJ/LUV is non-interference. The 1.8L and the 2.0L are interference engines.

I'm currently in the process of the cam fairly simple to time honestly if you have any mechanical knowledge. Be warned zzp claims only their turbo will work with the cam and hopefully you're tuned by zzp as well

let me know when youve installed new cams im looking to upgrade mine as well wanted to get them with the upgraded 72 valve springs so just saving up some more coin lol just bought some other parts

Who are you tuned by? Anyone other than zzp I wouldn't recommend.

 

[David184]

I’m tuned by BNR right now if I wanted to upgrade cams would that be an issue?

Yes... I as well am tuned by BNR also have zzp cam.. car doesn't idle for **** cold. Remote start just dies after running for about 30 seconds it's not been the best experience and I've been waiting for an update tune for about a month now and BNR wasn't thrilled when I told them about the cam told me it was pointless and a waste of money soooo

Vermont Tuning made it work for me. Share this article with BNR and see if he can help you. From what I understand the cams won't do much without a higher flowing turbo.

I talked to zzp about the turbo as well and they told me I had to buy the v3 because BNR's gtx250 wasn't a big turbo... I honestly just got the vibe they don't like each other

I'm pretty sure they don't.

Basically the cams increase the amount of time the valves stay open. This allows for the potential for more flow if the other components allow for more flow. I'll give you an example. My power goal is 300+ HP. I basically bought everything bolt on that I could including ZZP'S V3, and upgraded all the internals with the exception of the crankshaft. Right now, with the V3 I'm flowing ~180 g/s (~24 lb/min) at ~240 HP. That's maxed out. The V3 won't allow for more flow than that because of the housing design. So, I'm changing to a custom setup with a Garrett G25-550. From what I understand BNR'S turbo will flow more than that. They're website states up to 27 lb/min.

I think the main issue with the cam in our car is because of the variable valve timing... we basically have the same setup except I'm lacking e85 and the intercooler upgrade and I went with BNR's turbo

When I was talking to zzp about bnr not tuning their injectors they just said jerry (BNR) does not like tuning them and that they are good injectors lol

Hmmm I never had an issue with getting injectors tuned and I bought mine from zzp I only got the Bosch 42lb though so maybe that's why.. I will say not long after injectors I cracked the two middle pistons could just be coincidence not sure

I got the #60 injectors from zzp and he said he can’t tune them, not sure. Ouch 2 cracked pistons, that must have sucked

That's interesting to know 🤔 I'm trying to get on e85 and was going to get zzp injectors but I think I'll do some research now.. and yesss sure did! Sucked alot of money out of my bank account 🤣 but she's all forged now so hopefully we won't have any issues like that anymore 😁
