Starting a new project/Advise needed

[NITROUSJUNKIE]

Hello guys Im new to this forum and new to working on imports. I have built many race engines mostly on american cars but Im starting to do import stuff for customers by request. I need some advise or suggestions on building an Eclipse for a customer. I appreciate any info, I like to do a lot of research before diving into something I know little about.

The car Im working on is a '99 eclipse turbo..

Customer wants to go big turbo air to air etc... wide band 02

So far he has a t/3 -T/4 ball bearing turbo..Garrett.. I plan on making my own downpipe..

I was looking at a walboro fuel pump and a DSM link for this one??

Any ides on the right size of fuel injectors? Other parts needed to maker it run hard???

Any suggestions on a good set up??

Thanks for ANY comments...

Rod... Denver, CO
Here are some of my rides
'91 ZR1 427cid DOHC LT5, titanium rods, LPE cams, 4L80E auto, nx direct port
'40 Ford 448 CID SB2.2 SBC (nextell cup heads) glide w/brake, NX plate
'92 Typhoon V8 now...406 cid, pontiac alum heads, TH 400 w/brake, still AWD with drag radials all the way around, 500hp NX plate..

6xxcc injectors should get the job done... Walbro 255hp with afpr to compliment. Good choice on DSMlink. Otherwise, just worry about getting air in and out.

Very nice garage of cars btw... you currently have all of them? or previous projects

Thanks goalieman.. Yes I currently have all those cars in my garage....my girlfriend is not too happy...

AFPR????

Aftermarket Fuel Pressure Regulator. You will need one that has 1:1 ratio since its a boosted aplication. AEM and Aeromotive make good ones. I would also suggest some sort of manual boost controller as well, after market boost gauge ( stock is inaccurate ) and you have wideband covered. A good wideband would be AEM 6 in 1 Uego, it logs well with DSMLink.

almost forgot, get some NGK plugs if you dont already know about that, dont use BOSCH from autozone. Go to NAPA. 6's will do if you are going to run stock boost but if you are going to crank it up, which it appears you are going to do, get some NGK BPRE7ES. They should do you good. Get the normal ones, not the iridium or double prong. They cost about $1.85 each. Also only use full syntethic mobil 1 oil, 10-30w, nothing less. In the trans, use syncromesh or mobil 1 75-90w gear oil ( same with transfer case and rear diff ).

I think this covers the basics of a DSM

Thanks for all the input guys! One things for sure the aftermarket has exploded on parts for these rides....it doesnt make it easy to choose the right parts. One things for sure from what Ive read up on the engine can take a lot of abuse ..


At what point does it become needed to run a different MAF (GM maf etc..)? or a sheet metal intake?


Oops AFPR..I was never any good with abreviations!!!

The stock 2g Maf is good for around 450+ HP, after that most people go with a GM MAF and a GM MAFT (mass air flow translator so the dsm can understand GM language)

dsms will definetly benifit with a sheetmetal intake manifold and a 1g TB (throttle body)

http://www.dsmtuners.com/forums/showthread.php?t=96388

but once your at that stage it may be better to go with ARP headstuds and a 4 layer metal, or cometic headgasket, first.

ported exhaust manifold, 02 housing is also somthing you will want to do.

(and dont forget a good clutch for the added power)

A 99 Eclipse does not have an eprom ECU, you can't put DSMlink in a non-eprom ECU. Before you install DSMLink, you'll need to get a 1995 E-Prom ECU. More info here - http://www.dsmlink.com/faq.html

If you decide to do with DSMLink, go with 750cc injectors. They are about the same price as the 650s and can be easily controlled by DSMLink.

Does the customer want a bigger turbo that the T3/T4 ball bearing garrett he already has??

For air to air intercoolers, there are many vendors that sell kits. I would go with www.extremeintercoolers.com, www.dejonpowerhouse.com or www.slowboyracing.com

Cheapest wideband is the Innovate LC1, I don't think (I'm not sure) if you can log wideband in DSMLink though. Here's the manual for DSMlink - http://www.dsmlink.com/DSMLinkV2.5 User's Guide.pdf

For fuel, get a Walbro 255 pump and an AFPR (anything other than the crappy B&M one).

Other parts, you'll need are cat back exhaust, intake pipe (www.dejonpowerhouse.com) sells them. Anything that you don't have that is listed on the Upgrade path - http://www.dsmtuners.com/sub.php?page=2gtupgrades

EDIT: If you want a wideband, I recommend the AEM UEGO.

You are right, sorry late at night and my mind got stuck on Aftermarket for some reason. .

Don't worry about it. Today I was trying to undo the fitting on my turbo oil line and was screwing it in tighter rather than loosening it. Took me 15 minutes to figure that out. Try and explain that one away! .

Anyway, for NITROUSJUNKIE, has this customer of yours given you a budget to work with? If we had some more solid numbers, I'm sure someone could give you a shopping list that would fit the bill. What goals does the customer want? Top end boost or quick resonse? Maybe somewhere in the middle? Street setup or full drag car?

Guys thanks for all the info..Keep it coming in!!!

The customer is going with the t/3-T/4..Right now the car is stock except for a boost controller.

He wants a street/strip car with 18+psi boost.. No real set budget Im trying to get a better idea on parts and labor for him. Right now I have a deposit for $4k.. he told me whatever I wanted to do to it...Got to like that kind of customer!!! I did an engine for his brother a while back..CNC ls6 heads, cam,n20 etc...they are very happy with it so he had me do the Eclipse.

Most importantly he wants to blow the doors off of his buddies (stage 2??) SRT10

Right now as it stands Im doing the..
DSM link
Garrett ball bearing turbo
Header
Air to air
Down pipe & exhaust
Walboro fuel pump
big injectors
Thinking GM maf..Is it hard to get it to work right?

Any ideas on normal labor for all the installation?? Just tying to get a cost together..

You need to be more specific than the list above.

Header - Which one? And why? You can get a cast manifold, it'll be more reliable on a street driven car.

Air to air - Which one?

Down pipe & exhaust - 3" O2 back? with or without a cat?

Walboro fuel pump - You'll need a Walboro 255 with an AFPR as mentioned above

big injectors - get 750ccs since you are getting DSMLink. There is no point in going smaller.

Thinking GM maf..Is it hard to get it to work right? - - No, it is not hard to work with. With the GM MAF you need a MAFT (MAF Translator) to make it work on DSMs. Currently, DSMlink does not have a MAFT. The new MAFT Gen II can support up to 660cc injectors (last time I read it), and it can automatically adjust A/F ratio with a wideband hooked up.

The stock 2G MAS is good for upto 400HP. If you really want a GM MAF, another option is ECU Plus - www.ecuplus.com/features.htm It has a built in MAFT and is a piggyback computer like an SAFC or MAFT Gen II etc, but you don't need to buy an e-prom ECU.

You'll also have to look at an upgraded o2 housing. www.122performance.com has good cheap ones. If you want a SS one, there are many vendors that sell them, look at the parts catalog link.

Thanks guys..nice to know some of these things before starting the project...

This car has 3 inch exhaust all the way back with high flow cat. I have made my own 3 inch downpipe out of the turbo, just need to weld in O2 bungs and decide on an external wategate.

What is a good fuel regulator to go with?

Good external wastegate??

What is a good launch RPM when specifying for DSM link?

Also will I nned to specify GM mas before ordering the dsm link?

The most popular choice of fuel pressure regulator would be the Aeromotive AFPR w/ a nice liquid filled gauge. Stay away from the B&M.
