So I bought a mystery car... My lucky day... 2.2L experts please respond...

[s13eper]

So I bought a car with a mystery motor... Pretty cheap... Big turbo, please note the guy I was buying this from knew literally nothing about the car, it was a test drive and buy situation... Greddy FMIC, MR exhaust manifold, sewer pipe intake, JIC coilovers, cusco carbon strut bars... The seller claimed it was built as a 2.2 by the owner before him, head work, etc. The car is very fast, much faster than my previous s13 (sr20/HKS gt2540 .86AR/both manifolds/FMIC). The car was rusted through in lots and lots and lots of places... SCARY to drive hard... Busts out Dyno chart showing 375rwhp... $ exchanges hands, i bring it home... Where to start...

As i'm pulling off the valve cover, i notice only 2 of the coil packs are bolted down... man, i bet it pulls HARD with em nice and tight i'm thinking to myself... I pull of the valve cover, tomei cam gears, , upon further inspection, HKS cams, I could not find any other intelligible writing on the cams, I will rotate the crank tomorrow and see if the grind is marked... to top it off, crower retainers, and the valve springs look like they are made from larger diameter material, but I don't have a stock spring to check... They are not double springs...

Suddenly the story is getting more believeable, I still don't know what turbo is on the car though... maybe you guys can help, the markings on the compressor are ec1 m24.... thats it... i don't want to pull out the turbo yet, everything is going in another car soon, so I'll be able to see teh turbine then... in the next post i'll attach the turbo with a credit card fro size reference... Thanks in advance for any help comments or questions...

God it feels good to be behind a sr20 again...

No, I have no idea why they printed him a mph dyno graph, but its a 3rd gear pull obviously and shifting around 95 seems like 7k or so, I haven't driven a sr20 in almost 2 years now, so you guys can correct me if i'm off by too much... here's a few more pics...

for size reference

[s13eper]

it has a 5 bolt exhaust housing just like the t25/28 stuff fwiw... Thanks for any help iding that bad boy...

[s13eper]

what does that say???

Yup...

[s13eper]

does anyone have 2.2 dyno charts to compare, advice on how to tell if its for real, I know the answer to this question is take the heads off, but i don't want too, unless i need to. It does have a visible new looking metal headgasket... maybe one of you know the builder of the car, it came form minnesnowta... and it shows... right through the body...

[s13eper]

Ha i just noticed in the pics that it does say A/R .70 maybe that helps... I'll be searching again... tia...

The M24 is a T3/T4 hybrid based turbo. Its made by Garret I believe and cam in .68 and .70 AR

I haven't seen these on srs much... Are they common on dsms or hondas or something? just would like to learn some more about the turbo... google isn't helping much.

Anyone seen any other 2.2. dyno sheets?

TIA

http://www.turbobygarrett.com/...t.htmso messing around on their site, the only one that looks like the right a/r and compressor inlet outlet sizes is the gt2876r. rated at 350. It seems that dyno number of 373 on a relatively untuned engine (afc2) are pretty good for this turbo, could this be evidence toward the 2.2L ???

off to search more...

edit: my first search showed this is the gt25/40R, which is curious, bc i had the hks 2540 on my last sr20, and while it may have been a little different bc of hks branding, it didn't look quite this big, and i don't remember the ar on the old turbo...

ok, found two models

turbine .86A/R or .64A/R 440 or 380 rated hp respectively... That sounds more like my dyno graph... ok... now how can i tell if it's really a 2.2 other than opening it up... i could run it next to my old car, if the guy answers his phone and see if it sounds way different... hmm any ideas???

[spider_slayer]

taking jsut the head of wouldn't help much eathier.

since your pulling the engine out of the body anyway jsut drop the oil pan.

just curious...did you basically jsut buy a motor?

[s13eper]

nah, running car, but the body and 'frame' rails are rusted through in many places... luckily, my wife got me a 89 for my bday and its just been sitting til now. I just have to determine which is the donor car now... ha

reread the post, i drove it around and home... scary, bendy, twisty, fast, loose, holey, 240...

definitely a gt2876r... have to wait to find out if .64 ir .86A/R exhaust housing, judging by the lag, its the .86, but i don't know for sure...

if anyone sees this, i'm looking for whiteline sways, apex powerfc late model s13 blacktop, rear over fenders (20 or 30mm only), front usdm front over fenders (20mm), z32 alum calipers, hmmm.... what else... Greddy intake manifold... suggestions welcome here too...

[s13eper]

oil pan, remote filter, oil cooler...

heres an easy way to determine if its a stroker, but youll need access to another sr that is stock

take the coils and plugs out, put a magnet wand(extender magnet) into first piston at teh bottom of its travel and measure how much is out of the top. if there is a difference between the two, you have a stroker. specifically what kind will be the next question.

[s13eper]

brilliant my dear watson, I'll post tomorrow after work... maybe someone will be inspired to measure the distance in their sr20...
