Thought you guys might be interested in this

I`m currently in middle of building new motor for my car, hopefully should be built by middle this year sometime
Still waiting for some parts to arrive through post from overseas and couple other items are still in R & D processes
Anyway here are some of the specs:-

2.0 Beta II
2.2L Stroker Crank
Forged Conrods and Pistons
Main Stud Kit
Crankshaft Underdrive Pulley
Stage 2 Custom Ported and Polished Head
Custom Billet Camshafts
Adjustable Camshaft Pulleys
Head Stud Kit
Custom Inlet Manifold Mounting Quad Throttle Bodies (1 per cylinder)
Custom Tuned Length Turbo Manifold
GT28 or GT30 Ball Bearing Turbo
External Mount Wastegate
Front Mount Intercooler
550cc Injectors
Custom Billet Fuel Rail
Frontmount Oil Cooler

This is the main parts for build - Not included is the piping etc needed to connect intercooler, computer management system, blow off valve, catch cans etc etc etc

When i have the motor completely run in then i will look at setting up a nitrous system for drag purposes

I`m building this motor to hopefully be the first 10 sec Elantra - 11`s would be fine though but if it does go 10 then i`ll be ecstatic eek!

I might be bit too far fetched with my goals though rolleyes.gif
Not sure maybe it`ll only do 12`s not sure
All trial and error i suppose
What do you all think it`ll do?

Ok....

So your planning on running a qud throttle body setup with a turbo...

Why?

How are you planning on tuning both of these variables?

What kind of engine management system are you planning on using?

BTW... what pistons and rods did you get?

Also can you please be more detailed on your "stage 2" port and polished head?

Thank you and good luck

[note to visionz] get the flag ready [/note to visionz]

 

Answer to questions

Quad throttle body will give better response down low than a single

Tuning
All tuning is done through (haven`t decided yet) either a Motec M4 Pro or M48 Pro
If you know anything about these computers you will know what they are capable of

The pistons are ROSS RACING custom series
The rods will either be Crower, Carillo or CNK - Waiting till Chris from CNK finishes and tests his rods then i`ll decide

The head is getting done by RPW Performance have look at there page for more details

 

I'm with JAWS on this one??? so wait from my understanding the I/C piping has to go into the TB??? correct? how do you plan on making this happen??? and how do you plan on fitting a hood on there with the piping, since if I'm not mistaken the 4 tb's face upward, if you have piping somehow, the hood would not fit...

sorry man, but this sounds like someone a while back, that just posted a list of things, he had found on sites, and didn't know what they were for or what they did... I've yet to pull out the BS flag, but plus, explain your design...

P.S. also with that turbo and that manifold, are you keeping your stock fans??? sorry man, but there's tons of stuff missing... and for your info, with my setup, some calculators say I should be at 13 seconds or under, so with your setup how can you think you'll only be at 12?

yeah, have you ever seen what the quad tbodies look like? hmm... it's not gonna work. they bolt right onto the intake runners, and, umm..., where would you have the turbo intake piping then? are you gonna have some secondary intake manifold that goes from 1 pipe to four for your 4 (1 per cylinder...really?) throttle bodies? one or the other: turbo or qtb. also, you're getting a custom stage II p&p head. i thought a stage II would be an ALREADY benchmarked mod, as opposed to a custom job. how does this work?

 

This is only true for an NA engine when the air is being forced in it will have no effect whatsoever. Also its the lenghth of the horn that you fit to the quads that will effect where it has the most change on the power range. this is due to air velocity etc. So air velocity becomes a bit of a null and viod topic when you are talking about a turbo as the turbo itself forces the air in nothing to with quads.

 

#1. The beta 1 is known for better block strengh and relability. You might want to source an older (1997) block
#2. The 2.2L crank requires custom length rods and custom made pistions. The longer stroke of the 2.2L is suited to N/A applications, not turbo applications. The longer stroke means a very short rod. Very short rod means less pistion dwell at TDC and BDC and also poor cylinder filling at high RPM. Most turbo beta's DROP down to the 1.8L crank and rods. To have a better rod/stroke ratio and also to run flat topped pistions and keep a low CR.
#3. See above comments. The rods/pistions cannot be designed off the stock rod or pistions. The wrist pin/rod lenght must be done the hard way, math. You'll need to figure out how much rod length needs to be taken out, and how far down in the pistion the wrist pin needs to be located to allow for the pistion rings to be lowered due to the turbo.
#4 ARP studs are a wise choice on a boosted motor
#5. The stock crank Pully is also a harmonic Dampner. If you go with an under drive pully, go with RPW's. It is smaller in diameter, but the same weight as the stocker, and also contains a Harmonic dampner.
#6. Make sure the folks/shop doing your head work know that it is intened for use in a turbo vs N/A. N/A valve/head work is MUCH different than Turbo/forced Induction head work.
#7. Make sure the folks working on #6 know the specs of your cam. It would be a good idea to le the person building your exhaust manifold and intake manifold know about the cam specs so they can optimize the design of both to compliment/work with the cams.
#8. Not possible. You can get an (singular) adjustable Pully for the exhaust cam, but the intake cam is driven via a sprocket/chain off the other side of the exhaust cam. And adjustments you make to the timing cam gear, you make to both the intake and exhast cam.
#9 Same as #4
#10 and #11. The two are mutally exclusive. You can have Quad Throttlebodies, but not with a tuned intake manifold. You can have a tuned intake manifold, but not with individual throttle bodies. Also, the quad Throttle body setup is a N/A modification. it does NOT WORK with a forced induction setup. Also, normally, "tuned" intake manifolds are a N/A mod. They do not normally show much of a gain on a N/A Motor. Forced Induction intake manifolds should be short, and straight.
#12. Should get you to about 400-450 WHP
#13. Gee, that's nice? How about a Blow off Vavle? You didn't list that? What exhaust manifold are you going to have?
#14. What size? How are you going to mount it? How are you going to get air to/through it?
#15. A tad small, but they should be good for about 350 WHP safely. 400 WHP if you feel like living really dangerously.
#16. Gee, that's nice. What about your fuel pressure regulator? What about your fuel pump?
#17. Gee, that's nice. What temp is your oil now? How big of a cooler do you need? Where will you mount it? Where/how will you get air to it?

It seems you raise more questions than you provide answers to. I highly suggest you do some more research. Pick up Maximum Boost by Corkey Bell. Read it cover to cover. Then go back and do all the math in the book for designing a system. Then come back and tell us your new plan.

I didn`t do all the designing of the motor
RPW Performance did that for me, i just told them what i wanted

Random
I`ll try to answer questions here if i don`t know the answers i`ll talk to David at RPW and get them

#1 RPW have the block there and as far as i know it`s a Beta II
#2 and #3 All these items ARE custom designed - None of these products are available off the shelf
#4 Agreed
#5 RPW ordered the crankshaft pulley for me so go figure
#6 and #7 The head, cams and inlet is all getting done at RPW Performance
#8 Typo - hit s by accident
#9 Agreed again
#10 and #11 Your saying quad throttle bodies don`t work?? Hmmm have look at Nissan GTiR`s - Quad throttle turbo 4 cylinder and works VERY effectively
I didn`t say intake was tuned length i stated exhaust manifold was tuned length
#12 This is still in R & D area I`ll let you know what we decide on
#13 The exhaust manifold will be a CNK item
#14 Will either be CNK or TRUST item - Getting spesc from Chris at moment on his cooler and also looking into TRUST coolers to see if there`s anything better - Again i`ll let you know
#15 I have also thought about this and am going to talk to Chris about it - I have set of 750cc Injectors here out of my GTR so they might be going in
#16 #17 Theoriatically (don`t think i spelt that right) it should be able to be mounted between intercooler and radiator, after air passes through intercooler it will hit the oil cooler. Peter (from advan performance) wants me to mount it under one of the front guards with an air duct going to it so this is still undecided where to put it

I wasn`t trying to state an exact formula for building this motor i was just stating the MAIN components of the build.

Yes - There are a LOT of variables i haven`t mentioned but i didn`t intend on putting them in in the first place

Any other questions just ask - Don`t have to take piss out of me for christs sake, i posted because i thought you might be interested - Geez i`m starting to think i shouldn`t of said anything till i`ve completed it

 

Alright now i feel like a goose rolleyes.gif
I just talked to David at RPW and it`s not the 2.0 we are doing it`s the 1.8
We were building the 2.0 with 2.2 stroker before we decided on the turbo system upgrade
Everything else stays though
Sorry bout that guys
