I've been saving up for a TT build for my 08 HR and I have questions

1. I plan on buying my exhaust here in the next few weeks, and I really like the HKS Ti exhaust. Would the HKS exhaust be suitable with a TT and a built motor?, or would suggest something else?

2. For TT kits what would anyone recommend between the GTM and Greddy kits?

3. My overall goal is to have a car that can take the abuse as a daily driver and a weekend track car as that is slowly becoming my hobby. I am looking for something that can handle that until I get another car. Or better yet if this was your car with these goals in mind how would you do it?

I searched and flame suit is on standby
Thanks everyone.

Don't know too much on the subject, however I'll offer my 2 cents anyways. As far as the exhaust goes pretty much anything from HKS is going to be of very high quality. I couldn't think of any reason why the HKS exhaust wouldn't work for a car with a TT kit in it.

As far as the actual TT kit itself goes it depends on what you want. I know for a fact (because I've looked at both kits myself) that the GReddy kit is more of a tuner kit. It leaves out the fuel mods to you the buyer.

The GTM kit comes with Garrett turbos (have never heard anything except positive things about Garrett turbos) and the GTM has both a tuner kit (similar to the GReddy) or a complete (they call it a: turn key) kit that includes everything required for a good TT kit that the GReddy and GTM tuner kit leave out.

 

I have heard that the HKS exhaust can be raspy (read ricer). I am of the mindset that you can't go wrong be matching the exhaust to the turbo system.

Either kit should be rather capable, I think it matters most where your end HP goal is going to be and if you want to chose your components to get there or buy them as a package.

Lastly, budget is always a factor. If you start with just the basics and want to build HP over time then the Greddy may be the best choice.

 

Chi, next time your at the beach come listen to my car. I'm running the EVO TT exhaust with test pipes. It's loud, but not as loud or raspy as the HKS. As for the kit, I went with the Greddy cause I got a good deal on it. If I had to do over (and had a HR) I would defiantly go GTM! And finally, buy a beater FIRST!!!! I have a 98 Altima I use for a DD. It only cost me $1500, a drop in the bucket to what I put in my Z.

 

Tony of Motordyne has his 3" true dual coming out soon, which is what I'm waiting for now - not for more power, but because of the interchangeable components (best of all worlds hopefully, for DD and track). I know he is designing versions for the HR Z.

 

1- For the exhaust go with the greddy Ti-c (evo TT is discountinued) very nice sound ,, looks amazing ,, preformes the best ,, if u dont want the greddy exhaust go with any 3" exhaust will be good for F/i and also wil be fun with the HR ,,


2- the tt kits : i say go with the gtm turn key kit cuz it is a full kit

GTM: ( turbos , piping , intercooler, 600cc fuel injectors , walbro fuel pump, CAI using K&N filters, gtm reflash, blow off ) and cheaper than greddy ,, just order the kit, install it and ur good to go !!

GReDDy: no fuel pump, 460cc injectors, the quality of piping is'nt that good, no blow off , normal intakes, greddy e-manage for tuning isnt that good ,, the intercooler is smaller than gtm

so the gtm is better in every thing ,, cheaper ,, better service ,, and they have everything u would ever need to ur 350z ,, i did bussines with them once and they were more than great

i was gonna buy the greddy's ,, but now im going with gtm ,, more than that gtm has upgrades till Stage 5 !! ,, so in future if u want to have a 1000+whp car just switch the turbos with the stage 5 and thats it , maybe the turbo switching will cost around 2000$ only ! ( besides the engine, fuel system and transmission)


3- have a good set of coilovers for track ,, aim for 400whp at first ,, build ur engine then aim for 550-600whp and have fun with a v6 TT daily use monster

 

BaZooKa thanks god u went with GTM if ur crazy for more power its the only way to go, but the guy here is asking about the VQ35HR engine not the DE the GReddy Tuner Kit for the HR does not include Fuel System/Engine Managment Stuff only Turbos/Intercooler/Pipes :P

 

Thanks everyone

Well the HR block has been proven to handle 500+ in stock form and I want a built block. With that said I guess 700-800 would be an almost conservative goal with a block built.

I was looking at the GTM packages and thought the stroked 4.5 HR block would be nice.

John I can't drive yet so when I'm home I'll call you

I don't see any reason to not pull out all the stops when I start my transition

 

I wouldnt say the HR is proven to handle 500+whp in stock form. Just because a shop does a few pulls at a "high boost" and claims they beat on it doesnt mean its true. Every shop I know of lies about crap like that it's business. Soooo many posers on here claiming they rag their cars and they have trailer/dyno queens that never see high rpm/mph.

Id put any amount of money me driving an HR with 450whp the same way I drove my stock/built block set-ups wouldnt last long. No shop on here would test me on that and expect to win.

With that being said, I just want you to realize most people dont succeed with wanting a daily driver AND a weekend warrior (if they are in fact decent at the weekend thing). Eventually you come to find out that it doesnt work. If I had an HR Id run low 400's whp and hope it lasted, thats plenty of usable power that you can hookup with on the street. Good luck in your decisions.

 

Thanks Alberto....I'll keep that in mind

 

+1 on the beater, my 87 mr2 has saved my **** a few times now.

 

I have to agree, we just dont have a big enough sampling to know truly how much power a stock block HR can hold safely. I'd go for two different tunes, low and high, run low boost for a while and see what happens. Let others do the "testing" for you.

 

That was my plan

 

+1... get a separate DD..you'll enjoy the Z more.

 

10/4

Hows the knee?

 

I will only comment on the exhaust. I don't think the HKS will flow enough if you build the motor. It may flow enough if you are staying stock block, but even then, I would look at a greddy or APS exhaust

 

I would think that you would be fine with a Single kit. I have installed quite a few of them... All with great results! and seeing you are from Chicago... we (Sound Performance) are right near by!!!

We have a twin kit as well that you are more than welcome to come by and see for yourself. Give me a call at the shop and we can talk further about your goals!

If you go with big enough piping anything will work. I have retained the stock'ish muffler (for now) and I am making 769rwhp.

My Z had this installed two weeks before I bought it...glad I didnt have to pay for it...but it sounds wicked..I love it.

oh and this:AAM Comp 3 in. Dual Downpipes w/ Open Dumps (For GReddy Twin Kit)

 

You will not be disappointed with our Twin Turbo system for the HR.

I wouldn't go past 500rwhp on the stock block, the less power you make the more reliable the car will be, so that is for you to decide.

As someone mentioned, you really can't beat the value you get out of our turbo systems. If you have any further questions please send me a PM or give us a call at the shop.

Thanks!
