Beretta.net

Okay, I have a 1995 Z26, already have all of the turbo plumbing made and what not, have a 10:1 fmu for fuel management, and a new 3100 engine with roller rockers...the springs are yellow so maybe they're the good ones?

But anyways, since the engine i'm going to put in it isn't in it yet, cam/lifter ideas anyone? And does anyone have some 3400 plenums laying around?

Then a short little question with the fmu, on bstuff they think that my lines will blow up...even though how i'm doing it is disconnecting the secondary fuel line from the coupler, then i cut the steel line off another beretta where it couples in and flared the end so how im going to hook up the high pressure fuel hose that I have is by using the flared fittings and hose clamps. But ive also been told that stock injectors can't handle that sort of pressure... Any suggestions that way, and do you have of those laying around?

The crane 260 cam is a good turbo cam. Engle cams has some roller turbo cams also.

The fuel lines should be fine unless you know they are starting to crack. You however do still need a high flow fuel pump since the FMU will put more strin on it. If it lets you decrease the fuel pressure too..use larger injectors

Tried Engle cams, couldnt find anything on either of their online catalogs, sent them a message and they said they didnt have anything.

With Crane I'm not sure which cam you're suggesting. I'm guessing http://www.cranecams.com/?show=b....amshaft

Because it has 260 adv, but it says max rpm is 4200.

So im guessing im just slow.

Guess ill buy the Walbro 190 lph like it seems most people have, what do you do injector wise?

The 260 cam is a good mild boost cam, that was the last cam I bought. It was $100 with lifters from Delta

The new cam is a N/A monster with over 300* duration on exhaust and 290* intake O.O

Any roller cams though? I'm looking at this crane 260 but it looks flat tappet...im slightly anti pulling out a roller to replace it with a flat tappet.

You are absolutely right, I didn't think about you having a roller cam, they are more expensive.

For the roller cams, I would suggest talking to Ben at 60*. He has a lot of research done on them and isn't bad on cost considering most companies won't even do a roller re-grind

Once I get the next motor converted to roller, I'll be in the same boat.



What are tuning with? Widening the LSA will make more power, but is more difficult to tune.

Yeah...that's what I was afraid of. But I think im willing to spend around 500 for roller+lifters. But since you got me all excited when u said u got your cam+lifters for 100 ive started thinking cheaper . Yeah, it's a gm crate that came with roller cam/lifters, but I used the lifters on something else and now im about to put that new engine in but... Dont like putting used lifters on new cams . So was hoping to just do both at the same time and give it a little more pick me up, but since the lifters themselves are like 100, doubt i can get a cam for 200-300. But i'll send him an e-mail and see what's up.

Nothing yet on tuning, it's a 95 so I'm kinda stuck in the middle of everything, can't e-prom and cant re flash. After I get the turbo in and running (hopefully it wont take my pcm long to make it streetable...) I'll look more into tuning. Kinda plan on playing with the beretta until I get sick of it, but have a nice engine to put in something else, something lighter... Fiero maybe?

But the big thing im afraid of is passing emissions with turbo+bigger cam... stupid 95...

if you need to pass emissions go obd2. just have a program that will pass and a exhuast.

theres alot of guys that also run stock cams for boost app. not saying you should or anything just consider it.
alot of lsx motors run the 04+ls6/ls2 cam and there pump 800hp with no drivablity problems.

I would talk to ben or give crane a call. as i'm alittle limited on what i can do at this moment and time.

if you want to read up on what cam to run. go look at ls1tech and search the sticky. they have a good write up on boost cams and what to look for.

Yeah, im getting tested here soon... 2 weeks past due just dont want to do it. I'll end up doing an obd2 swap when i can find a 96 beretta around here for me to borrow parts from. Have 3" mandrel which will go back all the way, wanted to straight pipe it and just throw on my stock exhaust for the test, but too much work to do that so ill prolly end up getting a high flow cat and putting it in with a resonator and muffler. (both of which will prolly just be empty tubes resembling those).

I'm still thinking of maybe just buying some better lifters and sticking with the cam, but ill call up engle, talk to eric (if i can find out what his name is over there). If you still want to check out your crane bible feel more than welcome . But I wont and cant force you into anything . If push comes to shove I can call up either mine or my uncles engine builder, see if they want to hot ring my engine. Even though just calling them costs more than what i got. Hell, if im going to do it, might as well do it right (aka, drop way too much cash).

I saw the cams on engles old catalog. Could have sworn they had it available as a roller by ordering it as a roller by sustituding part of the part# with some numbers or letters.
Crane sells rollers too, You just have to specify what grind you want compared to the flat tap cams. Curtis Walker "TurboZ24.com" had his made like that. Malzy and the 60degreev6 store suppose to have some roller cams too.

I was going to say use Small block chevy 1.7 ratio roller TIP rocker arms but they're hard to find. THen just use your stock cam.

If you can't find what you want...Just blow in it harder!

lol, yeah. I was looking at 3.8 roller rockers one day, not sure fi they would work on a 3.1 head, but they do seem bigger. Im thinking of just getting a 3.4 lower plenum and a 3.5 plenum. The 3.4 is basically a direct swap, what about the 3.5 upper? And what do i have to do to get a throttle body to work? Just order a bigger 35mm one? Was kinda hoping there was a way of just removing all the 3.5 electric stuff and putting my cable stuff in it's place, but that's prolly a hella lot of work. I'm thinking of just getting some new lifters and the plenums and calling it good for now... a new cam would be awesome, but i'll just build another engine if i like how this works. 3.1 or 3.4 block with 3.5 heads/plenums, then I shouldnt have to change the pistons to lower the compression. Then have it rely on boost, if I can get a good tune for it.

But im also going on a mission in a few months and ill be gone for 2 years, probably best if i just do what i listed above and worry about a cam/more boost when i come back. Just focus on getting the new engine/turbo in and trying to get it converted to obd2.

Ok, you got lots of questions.
Didnt you think of doing this about a year ago, maybe a little more.

My stock injectors failed to open at about 63 psi I think which gives you no head room with them BUT scott has had his open to 80 psi on his 3400 so maybe its just whatever you get.

The fuel pressure line on my car blew at around 100 psi.

No one makes cams except ben I'm pretty sure.

The 3400 TB bolts on to the 3500 with an adapter from 60 degree.

Your stock computer will not accept much more than a factory injector.  A set of 19# ford motorsport injectors may be too much and throw a code but it may work.  On a factory size injector (17 at 43psi) you will need about 104 psi at 5 psi of boost.  Not likely going to happen.  With 19# injectors you need 67 psi at 5 pounds of boost.  You can add an additional injector with an AIC controller or if your not to picky you can put the additional injector(s) on a pressure switch but the fuel curve is less smooth.  If jon can find out about hptuners that may be the best option unless you just want to copy what I did.  If I didnt have the injectors I'm using now already and knew what I did now I would have put in 21# ford motorsport injectors so I could run E85 instead of 91-93 when boosting.  The ford injectors are rated at 38 psi just so you know.  

Most all of this is in either the turbo thread or the 3500 top end thread.  Read through them there will be info.

Yeah, was over a year when I got all the turbo plumbing built, then asked questions, and instead of putting the turbo on, I bought a dragster.

Ive read the turbo thread/3500 uim thread twice each, but I like to ask questions on how other people like to do things, I like more than one persons opinion on a subject before I make my own . Ive read a few threads on what injectors to use, I've heard this and that. I've heard I can use 3800 injectors, Ive heard that accel injectors work (also heard they fail like mofos), Ive read about your ford injectors (they're rated the same but gm uses higher pressure (I think is what you said) which makes them an actual higher #) Been told to use a 190 lph pump, then to use a 255 lph pump. So no matter who I ask, what I ask them, im always going to get a different "opinion" on what to use. So thats why I send individual people messages and ask them exactly what they did. Ask IsaacHayes how much Ive bugged him .

Sorry, I just don't like being told to do what Ive already done...multiple times. But I do appreciate everything everyone has said and taught me.

So far im getting a LIM from a 97 trans sport so I dont have to change anything for the coolant hoses, Getting a UIM from a G6 that isnt VVT. Going to have a plenum spacer custom made, as well as an egr adapter/tb adapter. Sticking with the stock roller cam, who makes the best lifters? Stick with stock or go aftermarket, crane, etc? Going to try the stock injectors with a 255 lph pump behind it, rather go too big than not big enough. If I have problems with the injectors I'll have to look harder into finding the right tuner, still in R/D on what I want to do there. From what I can gather Mega Squirt is the way to go, but still lots...and lots...and lots of different threads on what to use. Have to find out more info on the DHP as well. But probably going to go obd2 after everything is in and running and see from there.

I sent you (wicked) a pm about pictures on how you routed your turbo drain/where you drilled the hole, was wondering if you read it? Didn't see any pictures on how you routed it and dont see you saying where you drilled it. But ill go and skim read it, because I probably missed it.

either 190 or 255 will work. ÂÂÂ Doesnt matter which. ÂÂÂ 3800 SII injectors (non supercharged) I believe are 22# and "should" work but I'm not 100% sure if the computer will be able to compensate. ÂÂÂ The stock work the best  ***** I meant lifters here******. ÂÂÂ Do you still have the 4t60-e? ÂÂÂ I'm sorry I dont have any pictures of that right now. ÂÂÂ I will take a few pics for you next time I see it. ÂÂÂ I drilled the hole right below the starter.

Yeah, I just recieved my 255 pump, if it's too much fuel, the excess "should" return to my tank. I've been told both sides on the injectors, so it seems to be a sort of shoot and miss thing. If I start running higher egt than I would like and start going lean, ill get some of those injectors and throw them in and cross my fingers...

Yeah, i still have the 4t60-e. If I start blowing up trans like loner does, ill probably try to round up a 5 speed fiero or 93 5 speed beretta and swap everything over. I'm hoping that if I build a 4t60-e-65hd hybrid it should hold together. Going to start bugging 3400 modified when he gets back from miami. Unless he's already back, then I better start bugging him now and see everything he did to his trans. .

I was thinking below the starter personally. I've seen a pic of someone elses set up and they were a little more to the passenger side and they used braided steel line. I think i may just raise up my car, take a look around and try to cut an identical spot in my new pan.
