hey guys im wondering, msa has this cam kit and a big bore kit that'll up ur engine to a 3.1. if i where to turbo this setup with a garret t4, will it work or will ther be engine failure. i gotta 82 na fi manual tranny btw. lemme no what ya think.

T4, and a stroker kit? You seriously have $6000+ to spend on building your engine right now?

as long as you go with low compression pistons then it's no problem to turbo the stroker. But you will have to put a considerable amount of money into the setup. You'll have to have the block machined to accept the bigger pistons and clearanced for the rods (needs to be done anyways). You'll either need an L28ET to start with as it's already set up for a turbo, or you'll need to do a lot of fabbing to make the turbo setup work with your non-turbo motor. Either way a little modding will need to be done to accept a T4.

If you're going to turbo it though then stay away from the cam kit. It's only worth the money on a non-turbo motor.

If you want to do a turbo stroker correctly, check this guy's L28ET Stroker: http://www.angelfire.com/extreme/280zxt/

Here's another thread about the stroker:

Do you have any money you could lend me while your at it?

lww

Jeff Priddy has well over $40,000 in his car and he's done probably another $100,000 worth of research and work on his own. When he's finished, he couldn't get his investment out unless he can get $200k out of his car.

Clearly, that will never happen. He doesn't do it to flip it at a Barrett Jackson auction.

Here's the most important quote straight from the ZHome.com link above:

"Bottom line, plan on over 5K to do it right. You can do it for under 2k, but you take some chances of reducing your longevity, power producing capability, etc... With stroker motors, it is a crap shot. For those looking at turbo strokers, I will tell you, NO ONE has built a good turbo stroker, because it costs too much to do both well. Well, apparently there are some getting close to doing both well, but that is still up in the air. Those that did try, skimped in the stroker part, because the turbo is what produces easy to see power. If you want a turbo, stick with the L28, unless you just have money to throw around, and want the ultimate power. In that case, throw a few grand my way! So what is important for the stroker? In order of importance, in my humble opinion:
1) The best machine shop you can find, (not afford, find, for if you can't afford it, then you are throwing money away).
2) F54 block. 3mm overbore is HUGE! Keep some of that strength.
3) Balance, Balance, Balance the rotating assembly. Enough said.
4) Money, lots of money.
With those, you will have a good start. Do lots of research, and pick the brains of everyone you can. You will start to get a clear picture when you do. - Good Luck!"

P.S.
Unfortunately, this will have to be my last post on ZDriver.com. I just realized I was at 1,999 posts and I don't want it to click over to 2000. The thought of having to post another THOUSAND messages is just too daunting... Thank you Mrs. Calabash - wherever you are. Good Night!

skittle

hahahaha lww very funny

Steven280ZX

well i figured id be spending about 6k actually... so if i got a F54 block and a turbo head w/e its called... 89mm pistons, new rods, crank, turbo, and hell lets throw in a cam, she'll work? and wait doesnt the garretT3/T4 hybrid thing bolt rite on?

jfairladyz

The T3/T4 hybrid turbo will bolt right onto the L28ET exhaust manifold, yes. But a standard T4 turbo will not. It needs the T3 exhaust housing to bolt to the manifold.

Steven280ZX

yeah on the setup i was thinkin about i ment a t3/t4 sorry guys i messed up there. but it'll work?

jfairladyz

The T3/T4 is a great turbo to go with. Great spool up and more top end. Nismopick is using a T3/T4 so he should be able to tell you how it works out on the L28. But it definitely works.

NismoPick

Indeed... but remember Steven: If you shove in more air, you also need more fuel. I'm still using the stocker 260cc injectors, and have them pretty well maxed out. I've got some 370cc's that I'll be using w/ a SAFC soon.

Proper A/F mixture is your best friend!

Steven280ZX

wow ur telling me this can work!?!? and all this time i thot i was dreamin!

Steven280ZX

oh yeah right i fergot about uppin the injectors i thot HKS 370cc would do the trick and wen i got rich again after all taht spendin id grab a custom fuel rail

NismoPick

You need to get out more There's lots of webpages of guys doing upgrades to their L28ET.

Steven280ZX

i no but do u really want me to do all that work wen i can create mi own thread where i get all the info i want in one place? come on

NismoPick

He that does his own research, becomes wise! HeHe... we'll guide you to build a monster Z if ya not careful.

Steven280ZX

isnt what i just said a monster Z?

Bleach

You seriously do need to do more research then ask quesions. You should be able to find 3.1 stroker articles online. I really don't see the point.
Its just to say you're using an L-series engine? If you want 500hp, buy an RB with your $5000 then you've still got money left over. L-series are old technology.

lww

Seriously, Bleach is absolutely correct. The amount of time and money you'll spend on a 3.1L Turbo, could be better spent on serious head work, custom exhaust & downpipe, a fat turbo and a custom baffled oil pan.

Skully

like yea eh....dirty manitoban.

SHADY280

silly manitoban, get yur head out of the clouds. actually, if your gonna build it, go big, then you will only have to do it once. the rb requires fabrication, so if your not up to that task, then go l28et. its really up to you steve, and the questions you ask. inform yourself on all the options, the you can make a very educated desision

Steven280ZX

ok ok i did sum looking around and......... u guys r rite i dont no wut i was thinkin... yet another question then i figure doin a turbo swap is appropriete, what is a reasonable thing to do to the turbo engine to improve performance?

duowing

One thing I don't understand is why is everyone wanting to go the way of the turbo'd stroker, etc. You can build some pretty nice power from just that turbo engine alone for way less and you'll be putting out enough power to pretty much outrun just just about anything normally on the streets/freeway, not to mention have a pretty quick drag car.

To improve performance in the turbo engine, you can get a boost controller so you turn up the boost, but if you're going to do that you'd probably want to get an intercooler. Little stuff like that will let you push out more boost and get more horsepower. Bigger injectors to support more boost. I believe even the Z31 ECU swap which can be done for pretty cheap would be a step on the right direction.
