Power adders

[19GT92]

gonna throw everything at it but the turbo right know and then build another 3.1 block and turbo that one i want this na 3.1 to have some more pep untill i get the turbo 3.1 built and all the good stuff because here in fla no one has a turbo 3.1 so i am gonna have to build a na block to the lg5 specs

[Euro]

do they make roller tip rockers for the LHO 3.1L mpfi engine because i was gonna get them with bens chip with erg delete and the chip functions all tuned to max the engine out and a 2 bar map sensor for the LG5 along with the ffp under drive pulley to go with my custom intake and catco cat back exhaust and 160 t stat which should give that engine some pretty good pep i hope hell it will already light the tires with the mods i got already

 

longest single sentence ever...

 

and there isn't anything thats worth the time/money for performance on a 3.1.......cept boost

do they make roller tip rockers for the LHO 3.1L mpfi engine

- i have no idea if they make roller tip rockers for the GEN-II 2.8/3.1 MPFI engines. they probably do but will likely require modification. i wouldn't bother. just save your money and go with some stamped 1.6 ratio rockers from a '94/'95 GEN-III 3100. if you are rebuilding this LH0 for boost later on, add an aftermarket cam while you're at it (IF they are compatible with the 1.6 rockers that is (i'm pretty sure they are). and of course, choose a camshaft that will work well for a boosted application. personally i think the stock camshaft is fine though, ecspecially if you use the 1.6 stamped 3100 rockers. the LH0 and LG5 use the same camshaft FWIW.

- you won't want to buy a chip from Ben unless he started making chips with modified TGP (2-bar) code. last i knew he wasn't. if you want a good modified TGP turbo chip contact Dave (Invasion1) or Kenny (TGPilot) on http://www.tgpforums.com. Ben is very good (probably the best) at making performance chips for NA 60*V6 applications though. you might consider buying one of his chips if it will be a while before your engine is actually turbocharged. DO NOT USE the 2-bar MAP sensor until your engine is actually turobcharged. a 1-bar chip used with a 2-bar MAP sensor makes absolutely no sense. a NA engine will run worse with a 2-bar MAP sensor since the resolution of the 2-bar MAP sensor's 1-5v scale isn't as fine as a regualar 1-bar MAP sensor. as for EGR, consider keeping it. ditching EGR will result in NO performance increase, your gas mileage will suffer slightly (but then if you are building a performance engine, that's kind of a moot point), and you'll be polluting the atmosphere more and may not pass e-testing if you have that in your area. EGR can also cool the combustion chamber at steady cruise conditions, which may be beneficial if you are getting KR at cruise conditions (fwiw, EGR is not used at WOT). i only deleted mine because i wanted to add a distribution block there so i didn't have the vacuum lines running under the plenum, and i needed more sources in one easy to access location for things like MAP sensor, FPR, boost/vacuum gauge, BOV, hobbs switch for alcohol injection later on etc.

 

along with the ffp under drive pulley to go with my custom intake

 

- i haven't used the FFP UD pulley but i'd like to try that myself. as for custom intake; the GEN-II MPFI intake SUCKS (the lower intake manifold and cylinder heads do too for that matter!). don't bother building a custom intake. if anything get it extrude honed or maybe Ben can port it for you. of course, you really should consider ditching the GEN-II LH0/LG5 idea altogether if you want maximum performance. 3400 engine FTW! the big problem there is that the TGP's pre-turbo exhaust system doesn't work too well on the 3400. it can be done, but is far from ideal. if you were to consider the a 3400 to turbocharge instead, i'd recommend making custom turbo headers or log manifolds and a crossover pipe with a Garrett T3 flange. and some forged 9.0:1 Wiseco pistons, along with a larger T3/T04E hybrid turbo so you can run some REAL boost of course, that might be out of your budget.

 

and catco cat back exhaust

- as for exhaust, if you are going to turbocharge the engine, save money by buying your own mandrel bends and pipe from Summit. definately go 3"! get a Catco/Carsound high flow cat, no resonator and a Dynomax Ultraflo muffller(s).

 

and 160 t stat

the temp rating of the thermostat you choose will depend largely on the chip you have made, as well as the efficiency of the rest of your cooling system.

don't bother doing anything with a NA 3.1 period. save your time and money for turbocharging the LH0. the 3.1 is worthless without boost IMO.

 

as for turbocharging an LH0, read this thread

mentioning the Turbonator (or IAT resisitor mod for that matter) as a "mod" is a sure fire way to get flamed and destroy your credibility on car forums

 

buy anways, roller rocker gains probably all depends on the setup. for a stock engine maybe 5hp? for a modified engine that can take greater advantage of more airflow the gains will be greater. that's just assumptions on my part though.

 

there are only 3 real power adders:

 

- turbocharger

- supercharger

- nitrous

 

and those all basically do the same thing (i use that phrase very loosely) just different ways of doing it. they just add more oxygen to the intake charge.

 

or if you're a REAL man you'll cut holes in your floorpan and do it Fred Flintstone style for MaD P0W34.

 

If i do one of these i have to redo the motor. The stock prstens and valvetrain CANT handle the pressure. (even more so on a 2.8).

 

So about 10hp with rollers wtf??

 

The turbonater was something i found on google. Never herd of it thought "what the hell see what they say about it" Judge from that response i wont be getting it!

Ive just been looking for a few little adders to give the 2.8 more power so i can tell someone theat calls my car a POS i can tell them to settle it on the street!!

i don't know about nitrous really, but speaking from experience on the turbo (using 240,000 mile stock pistons with 3 of them that have been slightly knicked by valves due to a broken timing chain no less), i'm going to have to call BS on that. my 3.1 LH0 has never been rebuilt, and valvetrain is all still completely stock; even the valve springs. i doubt 2.8 pistons or other parts are any weaker. if anything the 2.8 crankshaft may even be stronger than the 3.1 crankshaft.

 

of course, maybe i'm just lucky. it's been turbo'd at 12psi for ~12,000 miles now and i'm pretty hard on it; delivering pizza in the car 5 nights a week and maybe having a little too much fun doing it it's very reliable (the only real reason i haven't driven it lately was due to rear suspension issues).

I just dont know if i can afford to risk it with my luck it would put hole in the piston plus i have a valve going on the back of the motor and i cant afford a new motor.
