HSR Swap

Currently Im running larger injectors and fuel rails along with larger TPI runners. Im not really sure if anything was port matched or not since i didnt build the engine. My question is Would swapping over to the HSR intake setup be any kind of advantage to me. Im running a built 383 with a paxton and no computer mods currently but will in the future. Any suggestions?

How the h*ll does that work ; stock tune would be way off for that setup
How does the computer account for the boost ; do you have a 2 bar MAP sensor?

Im looking into computer upgrades and tuning hence my question about the HSR setup to compliment the engine when tuning.

It actually runs ok other than the surging at idle at the moment. I think that might have to do with the TPS and the IAC more than anything at the moment. I think i just need to take the TB off and clean everything really good then do a relearn for the base idle.

If that dosent help then im gonna have to sneak the piggy bank out of the house and order some stuff before the wife catches me. lol

your only running a 1 bar map you might want too look into that and start reprograming. Dynamicefi.com has a ebl p4. Depending on the cam you have and engine idle vacuum maybe causing the engine surge.

Yeah that would have been the PO but I kept it that way cause of the vacuum switch for the water/meth injection (Its ran off the back vacuum port) as well as the nitrous fuel line is plumbed in there also. I have been looking at the EBL flash but it looked to me like it was just for the 6cyl computers not mine. Could be wrong there. My plan is to run a 3 bar MAP and a wideband O2. When I do start tuning since everything i read for boosted applications says thats the most accurate. I am still reading up on it though and the more I read the more im understanding it. Im really leaning toward playing with the Stock PCM and updating it to flash somehow then later on Going with a fast xfi system when the budget allows. I really dont think i wanna burn chips.

Re: HSR Swap

The ebl p4 is a upgrade for your 1227730 ecm. what were you going to upgrade too nvsram ? I would be money well spent to just get the ebl.

How do you figure that?
$600 for a HSR intake
http://www.summitracing.com/parts/WND-7540/
http://www.summitracing.com/parts/HLY-534-186/

( + some misc plumbing costs) on a engine you already have vs
how much for a 5.3 engine + swap costs?

Re: HSR Swap

Not too keep going off of subject but since you have accel runners, Im sure a high flow intake , a paxton. I would put the money into tuning and decide if you are happy with the tpi at that point. If you add the cost of a ostrich and data logger you will still want to burn a chip when your done tuning so the best value would be the apu1 and a g1 and a few sst 27sf512's . another $100 too the ebl p4 would be well spent with the ve learn feature and use of wb o2s.

I have no idea about the intake base being high flow or not but I have convinced myself im going with the EBL. I figure for 500$ itll do most of what I want it to do and later on if i out grow it I can go with the fast xfi like i really want.

Went to the track last night and the bottom end RPM power was great but it had no top end power past about 4-45k. I know this is an issue with TPI.. I really think im gonna need some injectors as well though it seems to me its running lean but Once I get the ebl and wideband O2 and fuel pressure gauge Im sure Ill be able to tell alot more about whats going on. I think im kinda at a stand still till then though.

Thinking a TPIS miniram may be in the future.
